Can I Use Masonry Paint on Wood?

Masonry paint can be used on many surfaces, including wood, and is an excellent way to protect the structure and increase its longevity. Often used for decoration, masonry paint is actually very good for insulation and energy-saving purposes as well as aesthetics.

You can use masonry paint on wood, but you need to follow specific steps regarding its application for maximum benefit. The steps for preparing the surface you wish to paint and applying the mixture are important to maintaining the wood’s appearance while gleaning the benefits are very important.

Masonry paint is an excellent way to preserve the quality of wood by not allowing dirt or fungi to obtain a hold, thereby increasing its longevity. It also helps to insulate the house and save on the electric bill while eliminating cold and damp spots or corners of the structure. Continue reading for more information on what masonry paint is, the proper way to prepare the structure, and best practices for applying it to wood.

What is Masonry Paint?

If you are new to painting in general and aren’t certain, it is important to know what masonry paint consists of and when it is used. Masonry paint is an acrylic-based paint that can be applied to almost any surface. There are colour options when purchasing it, and it is designed to adhere to most surfaces.

Masonry paint has multiple benefits, from curb appeal to practicality. It can add a specific look to your property that is appealing, and it protects the structure from the weather. It also can be used to insulate your home and save on energy costs.

Curb Appeal and Creativity

Masonry paint gives you options to be creative while practical. You can paint over masonry paint to give the structure a certain kind of feel, but different varieties of masonry paint come in various colours should you decide to go that route.

Masonry paint also increases the curb appeal of a home or structure by protecting its integrity. Wood can rot, splinter, or even break, and masonry paint will help hold it together and even keep out pests.


Rain, hail, snow, wind, and debris can all damage wooden structures significantly over time and reduce the life of the frames. Masonry paint helps the structure withstand the weather by sealing cracks and covering the wood so that moisture drips or bounces harmlessly off of it.

Insulation and Energy Efficiency

Just as masonry paint helps to keep out the elements outside of your home, it helps to keep the heat or air conditioning inside the home as well. Cold spots and drafts are eliminated if masonry paint is applied to the entire exterior of your home, and you’ll find that your energy bill will decrease while your comfort level in your home will increase!

Essential Preparation

In order to paint over wood with masonry paint, you’ll need to follow some very important steps before you even begin the application. Since wood is porous, applying masonry paint directly onto the wood would cause it to seep into the structure and possibly damage it when it dries.

A primer is necessary before applying the paint, and before applying that, you need to be sure the surface is as clean and smooth as possible. You also need to be sure to have the essential tools for the task and that the conditions are right to paint.


You need to have a mildew-resistant primer such as this one for the surface you wish to paint. You’ll need:

  • Ladders if you’re reaching
  • A brush with an extendable handle
  • Old clothes you don’t mind staining or discarding will be very useful as well

Be sure you decide on a color or type of masonry paint and that you have enough to cover the surface area you wish to paint as well. Make sure that you have enough of both the primer and the paint, keeping in mind that rougher surfaces may require more than normal based on square footage.

350 square feet typically needs a gallon, but if it’s a rougher texture, a gallon may only cover 300 or even 250 square feet. Be sure to read the labels on the back for help deciding the quantity.

Be sure that if you use a latex primer, you also use latex paint, as mixing oil and latex may cause the two liquids not to stick together.

Outdoor Conditions

The outdoor conditions for the duration of the paint job need to be optimal. Be sure that the forecast looks promising from the time when you plan to start to about 24-36 hours after you finish.

Of course, there is no perfect way to plan for the weather’s unpredictable nature, but the more you can ensure that rain, sleet, snow, heavy winds, or frost won’t occur during the time you’re painting and allowing the structure to dry, the better. Be sure to keep an eye on your weather forecast for an optimal window to get the painting done.

Clean the Surface

In order to properly apply the primer and the masonry paint afterward, the surface needs to be free of things like:

  • Dirt
  • Ice or frost
  • Insects, spider-webs
  • Liquids and oils
  • Natural growths like moss or ivy
  • Other debris

Really be sure to pay attention to corners where things tend to fester and go over the surface a few times before breaking out the paint. Remember that wood is more fragile than brick or cement, so be careful not to chip or splinter it while scrubbing the surface clean.

You will most likely need a power washer to get rid of heavy stuff like old paint, and a scraper with a wire brush will also help after the surface has been rinsed. A wet sponge with dish soap is good for dirt and grime if the surface is relatively clean.

Applying the Primer

In the case of applying primer, always check the manufacturer’s instructions before you begin. While the application process is usually universal, you want to ensure that you are following application instructions. You should also always:

  • Avoid inhaling or swallowing any of these liquids
  • Be aware of the chemicals within these paints and primers
  • Have proper protection
  • Make sure that you aren’t allergic to the chemicals
  • Take breaks while applying if you get light-headed or start having vision issues

After checking the manufacturer’s instructions, using a roller, start to apply the primer to the wooden structure’s surface.

  • Use extended even strokes
  • Start from the corners and work inward
  • Be sure to cover the entire surface with one coat and let it dry based on the manufacturer’s recommendation before applying the second coat in the same fashion

Be sure to give both coats ample time to dry, and wash off the roller while you wait as you’ll be using it again when applying the masonry paint itself.

Ensure that you leave a smooth surface after the primer is on so that the new paint application is easy. You can use sandpaper to smooth down the surface after the primer has dried.

Applying the Masonry Paint

Much like the primer, apply the masonry paint to your surface in long smooth strokes. Without endangering yourself, try to work hastily such that you aren’t covering dried coats with fresh ones, as that would risk flaking. If you want to apply two coats of masonry paint as well, be sure to sand down the surface in between coats. Much like the primer, always check the manufacturer’s recommendation before starting the application process and follow their instructions.

Enjoy Your New Look!

The work you put into your exterior walls will pay dividends in the form of financial savings and aesthetically pleasing appearances. You will preserve your structure’s life and insulate your home after having completed the job, and now all you have to do is watch the savings compile!
