How To Get Mold Off Concrete Patio

I Have A Major Moisture Issue Along One Wall In Basement Particularly Behind Furnace Duct

EASIEST Way to Clean Moldy Concrete Patios, Driveways, Sidewalks // Pressure Washing Concrete

The white, fluffy substance is efflorescence and the black spotting on the wall is mold growth. Efflorescence occurs when moisture moves through the concrete and deposits minerals/salts on the surface. In a basement, this can be a complex issue. First, I recommend looking at your downspouts and ensure they are moving the water far away from your home. Your goal is to reduce the moisture load in the soil near your home.

If this doesnt solve the problem, youll likely need a sump pump and possibly an interior footing drain. While expensive, they are often the only way to completely solve the problem. In most cases this will involved removing the wall in the problem area so the footing drain can be installed at the very edge of the concrete slab.

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!

How Do I Remove Mold From Concrete

Thankfully, because of the extreme durability of concrete, removing mold growth is a relatively simple process. Unlike sheet rock, framing or carpeting, you dont need to worry about damaging the underlying material.

If its a large area, a professional should perform the remediation. Theyll setup containment and HEPA filtration to ensure the spores dont spread throughout your home during the cleanup process. If the area is relatively small, you can likely tackle it yourself.

The removal process typically requires the use of both a fungicide and physical removal of the mold. The fungicide will deactivate and kill the mold spores, but staining and discoloration will likely remain. This is often addressed with HEPA vacuuming, scrubbing, steam cleaning, sandblasting, etc. In large commercial settings, dry ice blasting is occasionally used to remove mold from concrete.

A note about expectations

While cleaning the active growth from the concrete is relatively straightforward, some staining will often remain. This is especially true when dealing with black mold growth. The pigment left behind by the growth can be difficult to remove. Its important to remember, this staining is not a health hazard, nor can it regrow. Its simply a byproduct of the original growth. If the discoloration remains after the initial cleaning, paint the concrete with a stain blocking concrete primer.

Homemade Mold Remover Spray Recipes

Use the spray suggested for the type of surface youre cleaning. Do not use these sprays at the same time or immediately after each other since their ingredients should not be combined. Do not store unused portions theyll lose effectiveness after 2-3 hours. Keep the sprays away from children and pets, and use proper ventilation at all times.

Cleaning Mold Off Unsealed Drywall

* Concrete Paver Molds

Unfortunately, its not so easy to clean mold off unsealed drywall. Drywall is porous, which means the mold may be visible on the surface, but its also growing inside the pores. Without water-resistant paint, its very likely that by the time you notice the mold, its already inside the drywall too. You can look for mold by cutting inspections holes into the drywall. Remove the insulation and use a mirror to inspect the other side of the drywall.

If mold is growing on the insulation, it will need to be removed and replaced. Likewise, if you find that your drywall has mold beneath the surface, you will need to remove and replace it as well.

Unless youre trained in mold remediation, the most you can do is temporarily reduce the overall mold growth by using a mold removing cleaner and scrubbing the visible mold away. You will need to contact your local mold experts for an inspection to discover the full scope of your mold damage. Even if you clean away all the mold, if it still has a source and some mold remains, it will continue to grow back.
