Painting concrete block walls is an ultimate way to get rid of those dull looking gray walls. Most commonly, the basement areas, play rooms, and storage spaces have such walls which you may have not worked on. You can add your own ideas too and give it a decorative touch.
Prepare the Surface
Start by cleaning the concrete block with pressure washer. Use pressure up to 2,000 psi on an unpainted wall to avoid any damage to the mortar. Use soapy water and a brush or scrubber if required. Next, get the damaged or missing mortar repaired. A premixed acrylic mortar can be used to fill up such patches.
Seal the pores and holes, and make a plain surface by using acrylic block fill primer. Prime the entire surface including the recently filled mortar. Make the surface plain and let it dry. Fill all the cracks and gaps using a good quality caulk before starting the procedure. Once the cracks are repaired and the wall is ready, move on to the next step.
Choosing the Paint Color
Choosing the paint color is an important part. If you are painting a game room, go for vibrant shades like purple, red, orange, and bright yellow. If you are painting the basement walls, use neutral shades of bright colors to make the room appear larger. You can opt for a classic combo of gray and chrome yellow for a bright looking area. For a neutral look, pick lavender and off-white or lightest gray. You can use shades of beige. Also, a white color painted all over will look great on a wall, with just the pillars and columns designed in stencil prints. Moreover, faux painting one of the walls is an ultimate idea. With a number of techniques like ragging, sponging, combing, brush, color wash, or other special effects, you can convert a dull area into an elegant space. If you are remodeling the basement, don't forget the steps that lead to the basement.
Painting the Block
While painting the walls, make sure you pick a quality paint. Epoxy paint is known to be very durable, lasts longer, and is best suited for blocks. Mask the areas that need not be painted, like the windows, wooden frames, etc., using plastic sheets and masking tape or painters tape. Use a wide brush, roller or spray gun, and work carefully on each area. Make sure you don't overlap color layers. Wait between application of each coat so that it dries off completely. 2 - 3 coats are enough to complete the project. Usually, a third coat needs to be applied only if the first two don't give the desired color effect. Let the entire area dry off thoroughly before you start using it.
By painting these block, you can instantly spruce up an unused space surrounded with concrete walls. While painting, make sure you prepare the surface properly so that it does not get damaged easily and lasts longer. Also, you can get the desired effect of colors only if the base is well prepared and plain. If your basement flooring along with the walls is still unfinished, you can consider painting the basement floors as well.
