Quick Tip: If you’re working with an interior concrete wall or floor and there are signs of water damage on it such as it is beginning to peel, painting over it will only provide a very temporary fix to the situation. It will be back to the damaged state in no time flat. The underlying problem will still be there. In this type of situation, it is best to hire a professional to check out the situation and in consultation with you, come up with a plan to fix it. Before proceeding to the next step, let the concrete dry – very well. You don’t want any issues with trapped moisture in the future.

Patch Holes And Cracks

Addressing holes and cracks in concrete surfaces is a crucial step in ensuring a flawless finish for your painting project. To effectively patch up small imperfections, utilize a putty knife to apply concrete compound into the damaged areas. Following the application guidelines and drying instructions provided on the packaging is essential to allow the compound to cure properly and achieve optimal results.

While filling in the holes and cracks, it is normal for the surface to not be perfectly smooth initially. This is where sanding comes into play. Use sandpaper or a sanding tool to smooth out any rough edges and uneven surfaces, ensuring a seamless transition between the patched areas and the rest of the concrete surface. By taking the time to address these imperfections and ensure a smooth foundation, you can pave the way for a professional and polished paint job that enhances the overall appearance and durability of the concrete surface.
