Buyer’s Guide
Color
Most paints for concrete walls such as masonry or epoxy come in limited colors like grey, white, or black as they’re most commonly used in garages or basements that are used for storage and not another reception room.
If you are going to be using your basement as a room to spend time in or even as a gym, then we’d recommend going with darker colors as they won’t show marks or dirt as much and will not clean less frequently.
If you do intend to use your basement as a room to relax in and want to paint in a color of your taste, then you’ll need to make sure the concrete paint you’re using allows you to paint a topcoat layer over the top.
Some concrete paints won’t allow topcoats to adhere to the surface so you’ll need to check the product descriptions before committing to your choice.
How Do You Apply Paint to Concrete Surfaces
Before painting your basement walls, you’ll want to make sure the surface is as clean as possible. You can do this by using a wire brush and mortar stain remover to get rid of existing remnants of paint or grime build-up.
Make sure the surface is completely dry before you move onto the next step which is sealing up any joints or cracks in your concrete walls.
There may be some cracks or holes in the concrete of your basement walls that are letting water through. You’ll need to seal these up before painting to ensure you have a smooth consistent surface and also to prevent water from damaging the walls.
You can now begin applying the paint to the concrete, a paint roller or spray gun will be one of the most efficient ways to do this, but the application will depend on the brand and base of paint you use.
Apply your first coat and give a sufficient amount of time to dry (according to the paint manufacturer) and then go in with another coating to make sure the concrete has sealed the surface.
