How To Paint Different Surfaces

June 24, 2025

When it comes to painting, the first image that comes to most people's minds is painting their walls with a roller.


But did you know there are actually many different surfaces that each require different painting techniques, tools, and even
paint types?


If you've got a bit more DIY experience, you may already know that trim calls for glossier paint and an angled brush.


For most people, the walls and trim are the main areas that they ever paint, so even experienced DIYers may stop there.


But there are actually a few other surfaces, such as your pipes or fireplace, that, while much less commonly painted, are still good to know.


You might not need to paint them now, but one day you might.


So put on your reading glasses, and let's begin.


1. Walls And Ceilings


First up are your walls and ceilings. These are the most commonly painted surfaces, so you might already know how to paint them.


If that's the case, feel free to skip this section and any others that you already know how to paint.


With that said, let's get back to painting walls and ceilings.


For your walls and ceiling, before you start painting, you need to prepare the surface. This involves repairing damages, cleaning, and applying primer if needed.


Before we go any further, a word on repairing damages. You could try to DIY the repairs, but if it's anything larger than a tiny dent or hole, we highly recommend that you leave it to the professionals.


Repairing wall and ceiling damages is a deceptively tricky task that most homeowners just don't have the expertise and skill to tackle.


Any DIY attempts usually result in an even uglier sight than the original damage.


So trust the pros, and leave it to the pros.


After repairing the damages and cleaning your walls and ceiling, you’ll need to apply primer (2-3 coats) if:

  • You're painting relatively new drywall or plaster
  • You're painting a light color over a dark color
  • You've removed wallpaper
  • You've patched the area. Note that you can apply primer over only the patched areas if you didn't have to patch too large an area. But if you've had to patch a large area or many areas, it's best to just prime the entire painting surface.


Once the prep is complete, paint with a roller using the “W” technique.

DIY house painting guide.


2. Wooden Surfaces (Trim, Doors, Cabinets)

After your walls and ceilings, your trim, doors, and cabinets are the next most frequently painted surfaces.


If you're looking for professional cabinet painting in Raleigh, NC, contact Renewed Walls Painting today at 919-759-6676 today. We'll get your cabinets painted on time and within budget, every time.


For those painting your own cabinets, note that this section is on painting wooden surfaces, which is the most common material for trim, doors, and cabinets, but if your trim, doors, or cabinets aren’t made of wood, please don’t apply the advice from this section. Instead, check out the next few sections to find the right section for your surface.


For painting wood, the process is similar to painting walls and ceilings. Before you start the painting, prepare the surface by filling up holes and dents with wood filler, then clean the surface.


An additional step that you have to take when painting wooden surfaces is to sand them before applying the primer. This is to remove gloss and imperfections so that your new layer of paint adheres better.


Then, once you’ve prepped the surface, you can begin the painting.


For your trim, doors, and cabinets, they’re high-touch surfaces, so the paint you use needs to be tougher than the regular paint you use for your walls and ceilings.


Make sure to use glossier paint, and paint with an angled brush so that you can reach awkward angles easily.


When painting, paint one way and follow the grain, and aim for longer strokes. If you’re still unsure of the technique, check out our guide on house painting techniques and tips, where we break down various
painting techniques in detail.


3. Metal Surfaces (Pipes, Frames, Radiators)

Metal surfaces don't absorb paint like drywall and wood do, so you can't use regular paint, as it won't adhere to smooth metal surfaces properly.


When painting metal surfaces, your paint and primer need to be specially formulated for metal so that they're rust-inhibiting and have stronger adhesion.


You’re also going to be dealing with rust, as well as expansion and contraction since metal is a good conductor of heat.


As such, your surface preparation will also need to be slightly more tedious.


For the surface preparation, start by scrubbing away rust with a wire brush.


Then, sand the surface to create tiny scratches. Metal itself is smooth and hard for paint to adhere to, so by creating a rougher surface with paint scratches, paint is able to “grab” onto these scratches and adhere better.


Note that this is the opposite of trim, where the purpose of sanding is actually to remove imperfections like small bumps.


After sanding, you'll need to clean off any remaining dust or dirt. It's important that you use a dry or slightly damp cloth for this. Don't use water directly, as that can cause rusting.


The final step after cleaning is to apply rust-inhibiting primer formulated specifically for metal. This not only helps paint adhere better, but also helps prevent corrosion.


Moving on to the actual painting, like we mentioned above, you should be using paint made specifically for metal that will help inhibit rust and can adhere to metal surfaces properly.


If you're painting radiators, the paint also needs to be heat-resistant.


Then, for the painting technique itself, paint in thin coats. Since metal is smooth and paint won't adhere easily, thick coats may not be able to adhere properly.


In summary, when painting metal, prepare the surface by sanding, clean with a cloth instead of water, and use rust-inhibiting paint that's specifically formulated for metal.


4. Brick And Concrete Surfaces

While they may not look it, brick and concrete surfaces are highly porous, so when you paint over them, there's likely moisture inside.


If you use non-breathable paint, you'll end up trapping this moisture, which will over time evaporate and turn into water vapor. Since water vapor is a gas, it takes up more space than liquids, so the water vapor will exert pressure on the paint as it has nowhere else to go.


Eventually, this pressure will lead to blistering and peeling.


To prevent this from happening, you need to use breathable paint specifically designed for masonry.


These types of paints only let water out and not in, so you won't have to worry about water damage underneath the paint.


For the surface preparation, as usual, you'll need to clean the surface, though a little differently.


Brick and concrete are rougher and have tiny holes and crevices, so to get rid of the dirt thoroughly, you need to use a wire brush or vacuum.


If you're cleaning bricks that have soot on them, you'll also need to use a degreaser to remove the soot.


Once you've thoroughly cleaned the surface, apply masonry primer before you start painting.


Then, from here, all that's left to do is to paint with masonry paint.


5. Wallpaper


In general, it's usually best to remove wallpaper before painting, because all wallpaper eventually peels off.


When your wallpaper starts peeling off, your paint comes off with it too, wasting your effort and all the money you spent.


What's more, wallpaper that's been painted over is messier to remove, as you'll also have to deal with chipping paint.


A lot of times, wallpaper usually also has small bumps that become much more noticeable after they're painted over.


As such, most of the time, it's best to just remove the wallpaper before painting.


Having said that, wallpaper removal can be a tedious and costly process, especially for older wallpaper or more stubborn wallpaper.


As such, in very specific cases, it can make sense to paint over wallpaper. Specifically, if it fulfils all these conditions:

  • The wallpaper is firmly attached, so it's unlikely to come off anytime soon
  • There are no bumps and the wallpaper is smooth
  • The seams are tight and flat against the wall
  • There isn't any kind of water damage, mold, or staining


Even if it does fulfill all these conditions, it's still better to remove the wallpaper before painting, but if you're trying to keep costs down and don't mind a shorter lifespan for your paint job, here's how to paint over wallpaper.


First off, there shouldn't be any loose seams, but if you're moving ahead with painting your wallpaper even with loose seams, glue them back tightly first.


Next, sand the edges slightly so that they're flatter and less raised.


Then, apply a shellac or oil-based primer. This will keep moisture out and help prevent bubbling or peeling in the future.


Make sure to avoid water-based primers, as the moisture can soften the wallpaper glue, causing it to loosen and peel off.


From here on, you can paint as usual for normal walls.


Ending Tips


Before we end off, one last thing to note is that if your home was built before 1980, make sure to test for lead paint first.


Lead was added to paint up until the late 1970s, so it could be on any of your surfaces. If it is, and you disturb it by scraping, sanding, or cutting, it can release lead dust, which is extremely dangerous.


Lead dust is highly toxic, particularly to children and pregnant women, and can cause brain damage, kidney damage, nervous system issues, etc.


In short, lead dust is extremely dangerous, so don't take the risk. Make sure to test for lead paint if you're staying in an older house.


And if you're still unsure of how to paint any of these surfaces or you're not sure what surface you're even painting, don't hesitate to give us a call.


Whatever surface it is, you can trust

A homeowner painting his interior home walls yellow during winter
November 1, 2025
Yes, even during cold weather or winter, it’s safe to paint inside your home as long as the conditions are right. Even though you’re painting the interior of your home, which should be much warmer than the exterior during cold weather, if it’s too cold or humid, the paint still won’t cure or adhere properly. During cold weather, your windows will also likely be closed, so you also need to make sure there’s enough ventilation. This is essential to ensure that the air doesn’t become too humid, as well as to ensure your safety, because even low-VOC paints can be quite toxic if trapped in an enclosed space. As such, it’s important to take the necessary precautions and ensure the conditions are right before you start painting. As long as you control the temperature and humidity and ensure there’s adequate ventilation, indoor painting is 100 percent safe, even during cold weather or winter. When Is Indoor Temperature Too Cold For Painting?  Anything below 50 degrees Fahrenheit is too cold for painting. Below that, the paint may take much longer to dry and cure, and even after drying and curing, may still not adhere properly, leading to peeling later on. It may also develop streaks, blotches, or an uneven finish. While 50 degrees Fahrenheit is the absolute lowest that you should go, ideally, keep it to 60 degrees Fahrenheit and above. This will help your paint dry and cure faster and better. Indoor Painting Tips
Wood stair railings elegantly painted with semi-gloss brown paint
October 7, 2025
Your stair railings don't take up as much surface area as your walls or even your cabinets, but just like how adding a vase can elevate a dining table's aesthetics, painting your staircase railings can improve the overall look of your home. For example, painting your railings a sleek black can instantly change your home’s vibes from farmhouse to modern and contemporary. Painting stair railings is generally less tiring than painting walls and more straightforward. You do need to be a bit more careful, as you'll have to manoeuvre around various tight spots and corners, but overall, it’s a lot less painting to do, and it’s relatively simple, with fewer things to take note of. Here’s how to go about it. Gather Your Supplies  These are the supplies that you’ll be needing: Mild detergent and degreaser Sandpaper (Medium and fine grit) Painter’s tape and drop cloths Wood filler Paintable caulk Angled brush Primer Enamel trim paint in satin or semi-gloss finish Step 1: Carry Out Repairs Whatever you’re painting, you should never be painting over damages. Otherwise, when those damages worsen, they’ll compromise your paint and lead to issues like peeling and bubbling. Here are the various damages and how to fix them: Loose spindles: Secure any wiggling spindles with wood glue at the top and bottom if the gap isn’t too big. If it’s too big of a gap, use wood filler instead, let it dry, and then sand it smooth. Cracks, dents, and holes: Fill them up with wood filler slightly higher than the surface level, as it’ll shrink as it dries. Then, once the filler has dried, sand them smooth. Rust (for metal railings): Scrub the rust off with a wire brush or sandpaper, then continue scrubbing until the surface is smooth, and then apply a rust-inhibiting primer before painting.

Freshly sealed black asphalt driveway
September 9, 2025
Your driveway is one of the first things that passers-by and visitors see. It's also the first thing that greets you when you return home. Granted, most driveways aren't there for aesthetics, but a worn-out driveway can give your property an overall rundown and neglected feel. To prevent this, you don't have to splurge on an expensive driveway replacement — all it takes is some simple repairs and a new coat of paint (or technically coating). In this article, we're going to cover how to choose the right coating, how to apply it for both concrete and asphalt driveways, and other important things to note when painting a driveway. Here's how to ensure a smooth and successful driveway paint job. How Much Of An Impact Can Painting Make?  It's not just about looking nice — a new layer of coating is instrumental to ensuring the longevity and durability of your driveway. UV rays, moisture, and oil are the main culprits behind cracking, fading, and staining. A good protective coating shields your driveway from these damaging elements, adding years to its lifespan and dramatically reducing the amount of maintenance and repairs that you'll need to perform. And don't forget that with the huge facelift that it gives your home, it also brings up its resale value by quite a fair bit. It's not uncommon for a driveway paint job to yield a return on investment of 50% to over 100%, especially if you’re DIYing to keep costs down. On top of all these, consider that by protecting your driveway and helping to stave off any significant damage, the protective coating delays a $5,000-15,000 driveway replacement. So the impact a coating can have, particularly on your finances, is certainly more than enough to justify the time and capital costs. Here’s how to protect your driveway with a coating. Step 1: Choosing The Right Paint For concrete driveways, since they’ll be subjected to stressors like the weight of cars and friction from car tires, you need to use an extra-tough coating. And there’s no tougher paint out there than a combination of an epoxy base coat with a urethane top coat. These are two separate coatings that you’ll have to purchase on their own, but it’s necessary for maximum toughness. Alternatively, you could also opt for acrylic concrete coatings. Those are less durable, but much easier to apply. Layering an epoxy and urethane coating will give you solid protection. You’ll have: Strong UV resistance Excellent moisture resistance to prevent moisture damage Great abrasion resistance to resist wear and tear from tires and foot traffic Chemical resistance for protection against oil, fuel, brake fluid, etc By layering those two coatings, you’ll keep your driveway well-protected against the main damage culprits — UV rays, moisture, and oil. In comparison, acrylic concrete coatings still protect against UV rays and moisture, but they don’t hold up well against friction, chemicals, and oil. Consequently, if you opt for acrylic concrete coatings, expect to have to recoat about twice as often. Moving on to asphalt, asphalt is petroleum-based, and petroleum reacts poorly with most paints. As such, regular paints won’t stay on asphalt. Instead, you’ll need specialized asphalt sealers. These specialized sealers will soak into asphalt and restore its deep black color, as well as help keep out UV rays, moisture, oil, and chemicals, while also improving the asphalt’s flexibility. Step 2: Cleaning And Repairs If there's debris and dirt all over your driveway, your coating won't adhere securely, so cleaning is an essential preparation step. Cleaning
Applying waterproof coating to a roof with a roller
September 2, 2025
We live in an amazing time where new discoveries are being made every day, and technology can now do things we’d never have imagined possible a decade ago. In today’s world, your paint can do way more than just make your home look pretty. There are now paints and coatings that can clean themselves, heal their own scratches and scuffs, and even regulate temperature! This means lower energy bills, cooler homes, less maintenance, and safer and healthier living spaces. And that’s not all. There are even more amazing and advanced technologies in the works, and we’ll be covering them in this article too. Ready to find out what these smart paint technologies are and what they can do for you? Let’s begin! What Are Smart Paints And Coatings?  Before we get into the actual smart paints and coatings, let’s clear up a common area of confusion first — what actually are smart paints and coatings? Well, there’s actually no strict definition or a single quality that makes a paint or coating smart, and the technologies behind each smart paint and coating can vary quite a bit. In general though, paints and coatings need to be able to sense and react to the environment appropriately to be considered “smart”. So when there’s a change in the environment, whether it’s temperature, light, moisture, or even bacteria, a smart coating would sense it and react in a useful way, whether it’s changing its color, releasing a chemical, or some other reaction. However, a paint or coating can’t be considered “smart” just because it has a bit more added functionality. For instance, there are paints and coatings that reflect more sunlight and keep your space cooler, but those wouldn’t be considered smart since they don’t actually sense the environment, and they don’t react . The definition of smart is still slightly vague, but you get the idea — it needs to sense and react to be “smart”. Alright, now that we’ve cleared that up, let’s jump right into the smart paints and coatings. 1. Self-Cleaning Paints

Looking to revamp your mobile home? Or maybe you're just tired of driving around a relic on wheels. Either way, repainting your mobile home can make it look like new again, and turn it from a tired, weathered ride to something that you proudly show off to others. It also helps protect your mobile home’s exterior from the elements, and can even help maintain interior energy efficiency. Before you start painting your mobile home though, you should know that painting mobile homes requires different preparation techniques and steps, as well as different paint types from normal wall painting. The painting application method is the same as for normal walls, but given that you'll be painting either metal siding, vinyl siding, or fiberglass panels, you'll need to prepare them differently for the paint to be able to adhere to them. Since your mobile home will also be exposed to road debris, you'll also need to choose your paint carefully for toughness. And that's not all. There are a few other things that need to be done differently throughout the entire painting process, and it’s important to get them right for a successful mobile home painting project. You’ve got nothing to worry about though, because we’re here to walk you through the entire process. Let’s get started. Tools & Equipment
Clean white themed home office setup
August 19, 2025
When it comes to designing their home office, many people focus on the desk, the chair, monitor placement, plants, and so on. But one crucial aspect that people often miss out is the color of their walls, usually because they don’t think it really matters. However, multiple studies have shown that colors do affect your mood and productivity. Even putting studies aside, just ask yourself, would you be able to work in a completely black room? Or how about one with rainbow colors? Those are extreme examples, but just imagine yourself working in those environments, and it should be apparent that colors can definitely affect your mood and focus. To be fair, colors won’t double your productivity or magically make you smarter, but they do have very real effects on your creativity, decision-making, stress levels, eye fatigue, and so on. These effects may not be particularly noticeable, or perhaps they might not even manifest themselves, so sometimes, it can feel like your choice of paint color doesn’t really make a difference. But no matter what, the possibility that the right colors could help you complete your work quicker and produce higher-quality work should be enough to warrant some serious consideration for the palette you surround yourself with. And the more often you work from home and the longer your working hours, the more important this becomes. Either way, whether you work from home one day a week or you’re fully remote, here’s how to choose the right paint colors for your workspace at home. Color Psychology: What Can Paint Colors Do For You? Why is the blue sky relaxing? Why are sunflowers and the sun associated with happiness and cheerfulness? Certain colors just never fail to invoke certain feelings and moods. That's the power of colors. Here are some of the amazing things that colors can do for you Blue: Improves concentration, stimulates thinking, and provides mental clarity. Green: Similar effects to greenery in nature — rescues eye strain and lowers stress, enhancing comfort when you're working. Yellow: Sparks creativity and innovation, and also energizes your mind. Neutrals: Reduce visual distractions, thus helping maintain mental focus and concentration, and facilitating thinking. Red: Boosts energy and can also increase heart rate. Once again, these likely won't be very keenly felt. You’re probably not going to walk into a yellow-painted room and suddenly start getting a ton of fantastic ideas for your novel. However, if you’re mindful enough and observe closely, over time, you’ll probably notice the subtle influences of each color on the way you feel or the way your mind works. You might even notice them from the first moment you step into the room if the shift is strong enough or if you’re very self-aware. So now that you know the impact that paint colors have on your mental and physical state, and your productivity, the next question is, how do you go about choosing the right colors for your home office? We’ll now be going into more in-depth breakdowns of each color and explain when, where, and how to use each one, so that you maximize its positive impact. Best Colors For Calm And Focus A lot of times, calm and focus are the number one priorities for workspaces, so we’ll be starting with the best colors to achieve those — blue and green. These colors keep you calm and steady while at the same time helping your mind stay sharp and concentrated, which is why they’re so popular for workspaces. Blue
Leftover cans and buckets of paint after a completed house painting project
August 12, 2025
Nobody ever buys just the right amount of paint to use, unless they're really really lucky. In most cases, you'll end up with some leftover (or a little short if you're unlucky). What most homeowners do when they have leftover paint is usually to just store it away, and that's a smart move, because you may need it later on for touch-ups, repairs, or color matching. The problem is, a lot of times, after a year or two, when they eventually have need of the paint again, it's separated, crusted, or unusable. This is often because they didn't store it properly, but it could also be because it's past the shelf life of the paint. Whatever the case, knowing how to dispose of paint you no longer need or can use is important, because improper disposal can not only be very harmful to the environment, but is also illegal in some regions. If you're wondering why something as seemingly harmless as disposing of paint can be illegal, that's because it's not harmless, far from it . We'll go deeper into their dangers later on, but for now, you just need to know that they can be extremely dangerous if you just casually throw them into bins. And if you still choose to go ahead with improper disposal, you risk facing fines of hundreds to thousands of dollars, being liable for cleanup costs, and even being criminally charged. So don't just chuck your unused paint into the bin. Here's what to do instead. Why Proper Paint Disposal Is So Important Starting with the environmental effects, when you pour paint down drains, it can clog up pipes and disrupt wastewater systems. They won't be filtered out by wastewater systems either, since these systems aren't designed for paint, so your paint will get past these systems and go into waterways. Through these waterways, they then flow to rivers, lakes, and oceans, harming aquatic life and contaminating drinking water. That’s not all though. As if environmental damage wasn’t bad enough, improper paint disposal can also severely wound workers who’re working around it. In the best case, workers may only inhale the VOCs and experience symptoms like headaches, dizziness, and nausea. But in the worst cases, since paints and thinners are flammable, when mixed with hazardous waste like batteries, they can easily ignite or even explode, especially under heat and pressure in compactors, landfills, and trucks. This is exactly why it’s illegal to dispose of leftover paint without taking the proper steps first. You could end up costing people their lives or causing huge fires to break out. It’s also why the punishment for unsafe paint disposal can be quite severe, ranging from fines of hundreds of thousands of dollars, to even imprisonment. These punishments may seem severe just for throwing a can of paint away, but they’re necessary to deter the unthinkable harm that could happen from that mere can of paint. How To Not Waste Paint
Worker spraying white paint on the bottom of a balcony in Raleigh, NC

At first glance, using a paint sprayer seems like a much easier way to get your house painted than rolling. You just spray over the areas that need to be covered like spraying a hose, and voila , you now have an evenly covered, smoothly painted wall. No need to go through hours of rolling, and no need to make sure that you maintain consistent pressure and cover every spot on the surface evenly with your roller. However, in reality, it’s a bit more nuanced than that. Spraying is undoubtedly a much faster and more efficient way to go about painting your home. But while it sounds straightforward, spraying paint is a longer and trickier process than most homeowners realize. It comes with its fair share of additional steps and demands, which you need to be aware of before you go out and purchase a paint sprayer and start spraying your walls. Now, we’re not saying don’t spray paint your home. In fact, there are various situations in which you should definitely be spray painting instead of rolling. The key is to know when to spray paint and when to roll. Both spray painting and rolling have their pros and cons, and in this article, we’ll be breaking them down for you, as well as going over when to use each paint application method. What Is Spray Painting?  Spray painting works by atomizing paint into fine droplets, so that when you spray the paint, it comes out as mist. When done right, it not only allows you to cover large areas quickly, but also uniformly, and it gives you a smooth, professional-looking finish. The downside is that it requires much more preparation, and the technique is harder to learn than rolling. Without the right technique, you could easily end up with ugly streaks or even have to redo the entire paint job. As such, while spray painting can be faster, its speed also means that it’s harder to control, and when things go wrong, they can go downhill fast. What Is Rolling?

VOCs (volatile organic compounds) are chemicals that help traditional paints dry quickly and adhere well. If you can smell that fresh paint smell, it means that your paint contains VOCs. These chemicals are necessary for paint performance, at least for traditional paint, but unfortunately, they also pose health hazards and environmental risks. VOCs can cause headaches, dizziness, nausea, liver and kidney damage in the long term, and various other health issues. And kids, seniors, and those with asthma or allergies are more prone to those effects. This isn't usually a problem outdoors since they dissipate quickly, but indoors, in an enclosed space, with possibly poor ventilation, VOC levels can get quite high, leading to negative health effects. According to the Environmental Protection Agency (EPA), after a paint project, indoor VOC levels can be up to 5 times higher than outdoor levels. Obviously, this is less than ideal, which is why it's worth paying more for low or even zero-VOC paints. Still, some would argue that it's only a one-off painting project, so as long as there's proper ventilation, higher VOC levels won't pose an issue. We're here to tell you that's not true. But we're also aware you won't just take our word for it — and you shouldn't. Instead, read on to learn about what VOCs are, why they're needed, how much lower-VOC paints cost, and how to actually find them. Then, decide for yourself whether they're truly worth it. Let's begin. What Are VOCs?  First things first, let's go over what VOCs are, because if they're so harmful, why the heck do we put them in paints? VOCs are organic compounds that evaporate easily at room temperature. As paint dries, VOCs get released into the atmosphere, a process known as off-gassing. In other words, after the project is completed, the paint continues to release VOCs for days, weeks, or even longer. The thing is, VOCs are essential for traditional paint to adhere well and dry quickly. Without them, you could be waiting hours or even days for the paint to dry, and it wouldn’t adhere well, which means it’d start peeling in no time. Thankfully, the good news is that with the advancements in technology, today’s paints no longer require such a high amount of VOCs to function well. Some don’t even require VOCs at all. Here’s how modern low-VOC paints perform. Performance Of Low-VOC Paints Lower-VOC paints are every bit as high-performance as high-VOC paints, and can even beat high-VOC paints in certain aspects. Here’s how they match up. Application & Ease Of Use
