Methods For Cleaning Painted Cinder Block Walls Inside?

Cinder block walls can quickly accumulate dirt, dust, and mold, making them dingy and dull. To clean them, rinse them with water to wash away dust and surface grime, use a 500-PSI pressure washer to remove peeling paint, and combine 1 cup trisodium phosphate with 1 gallon of hot water in a pump sprayer. Spray the surface with the TSP solution, wetting it thoroughly. Scrub the cinder blocks with a stiff-bristled brush, and rinse them with clear water.

Identify the wall paint and finish to avoid interference during the cleaning process and prevent paint from adhering properly to the walls. Wipe the wall completely dry with a clean towel. For painted brick walls, create a cleaning mixture with mild dish detergent and warm water, but avoid adding harsh chemicals like bleach, ammonia, or trisodium phosphate. Use a pressurized tank sprayer to apply a detergent solution (degreaser) to a small area and allow about 10 minutes of dwell.

Pressure washing is best for real stains or removing paint. Use Xylene, apply straight, let sit for 5 minutes, then light rinse. Apply baking soda on the sponge before scrubbing gently to prevent any damage. Lay down a heavy plastic sheet or tarp and scrub with a solution of muriatic acid, which is used to prep concrete.

Can water seep through cinder block walls?

Cinder block foundations, also known as concrete block foundations, are susceptible to water seepage due to their hollow construction and mortar joints. These joints, which are weak points in the wall, allow water to seep through and collect within the walls. The rate of expansion and contraction of the mortar and blocks differs, resulting in the formation of cracks and spaces between the blocks and the mortar, allowing water to seep through the foundation walls. It is crucial to address this issue as soon as it becomes noticeable.

Can you waterproof a concrete wall from the inside?

If a foil test confirms water seepage in basement walls, remove existing paint and seal the interior with a waterproof product. This creates a watertight bond, preventing water seepage. Gutters and downspouts channel water away from the house, maintaining structural health. If you lack gutters or sump pumps, consider adding them. If already installed, fasten metal or plastic extensions to capture runoff or excess water and drain it away from the base.

How can I make my interior cinder block walls look better?

Painting is a simple and effective method for finishing concrete block interior walls, especially for those who prefer a bright, colorful coat. Priming is the only complex step, and a water-based latex primer is recommended. After priming, the wall can be treated like a blank canvas. A liquid membrane is another alternative to painting concrete blocks, but it may be necessary if concerns about water or moisture passing through the block or if there are cracks in the block. In most cases, painting is sufficient, but if there are concerns about water or moisture passing through the block or if there are cracks, a liquid membrane may be necessary.

Scrub a solution of water and a cleaning chemical onto the surface, let it dry, and use a dry mop to clean. Remove loose or flaking paint with 120-grit sandpaper or floor buffer. Check for curing compounds, which appear as small spots below the paint. Mix denatured alcohol and hydrated lime to form a paste, apply it to spots, and allow it to dry and harden.

If a thin crust appears, use a bristled brush to remove the dried paste. Seal and priming for concrete surfaces is crucial to prevent water from entering the concrete, causing issues like increased moisture and mold growth. Sealers, such as film-forming or surface-coating sealers made of acrylic, polyurethane, or epoxy, help protect concrete, prevent stains, and minimize clean-up and maintenance time. Two types of sealers for concrete surfaces include film-forming sealers made of acrylic, polyurethane, or epoxy, and penetration sealers.
