How Do You Prevent Mold From Growing On Concrete

The best way to solve a mold problem on concrete is to prevent it from happening in the first place. One way to do this is by eliminating the key element mold needs to grow, moisture.

For concrete patios, driveways, and walks, cut back foliage that creates shady areas on a driveway or walk that never see the sun.

Also, check for cracks in the pavement that can collect water and cause mold growth. Fill these cracks using a concrete repair product.

For areas where this isnt possible, consider treating the concrete with an acrylic sealer designed for outdoor use. This prevents moisture from penetrating the driveway or walk, eliminating the environment mold needs to thrive.

For indoor areas, fix leaky pipes that are causing mold growth. For basements that flood, consider using a product such as Drylok to prevent moisture from entering the basement when it rains.

If that isnt an option, a dehumidifier is also an excellent means of keeping the humidity level in a basement in check, preventing mold growth. Remove materials that can get wet and breed mold growth, such as cardboard, wood, cloth furnishing, and area rugs.

Also, check the areas around the foundation of the home. If the earth is not properly graded to cause water to flow away from the house when it rains, grading may be required. Keep leaves and other debris from piling up around the foundation, which can trap water and direct it through the foundation and into the basement.

What Is White Mold

White mold is often found in cool, damp environments such as in basements on walls and other structures. It is often confused with efflorescence, which is a mineral deposit that forms on foundation walls and other masonry surfaces due to water seepage. You can test to see if its mold by spraying it with water. If it dissolves, it is a mineral deposit if it does not, then its most likely white mold.

Will Vinegar Remove Oil From Concrete

Yes, cleaning concrete with vinegar will remove oil from concrete. You wouldnt believe it, but if youve had an oil spill in your garage, it will work.

Vinegar will remove mild oil stains from concrete. You might be able to remove even the deepest oil stains if you mix vinegar with dish or laundry soap.

To do this, mix half a cup of vinegar with soap and water. Pour the mixture onto the concrete and sprinkle it with sawdust. The sawdust will absorb the oil, and you can wipe the oil and sawdust carefully away after all of the oil has been absorbed. This will take about 30 minutes for unfinished concrete.

How does this work? The vinegar eats away at the cement in the concrete that binds its molecules together. The oil gets leached out of the concrete and absorbed by the sawdust so that when you sweep it away, most of the oil will be removed. Be careful not to sweep the dirty sawdust onto your clean concrete, or youll be cleaning that with vinegar next!

Prepare Your Room And Clean The Walls

We recommend that before you clean or treat the wall with any product, you wear protective gear. Safety glasses, rubber gloves, and a mask will protect you from exposure to the mold. You should also ensure you open windows and doors while removing the mold.

Once youre ready to start removing the mold from the walls, clear the area. Remove any furniture, fabrics, and electrical equipment from the affected area. Cover the floor with plastic sheets for protection.

Use a damp sponge with dishwashing liquid and clean the affected area to remove any dirt.
