Understanding Concrete Efflorescence How It Contributes To Ugly Foundation Walls
At Permaseal, we all respond to customer questions about concrete issues every day. Just about the most popular, and most perplexing for home owners, is what they should do when they find layers of white-colored, flaky residue on their basement wall surfaces. This powder is very popular on cement types of surface -- particularly in basements and crawl spaces -- and it is generally known as efflorescence.
What Can Cause Efflorescence?
Concrete is a permeable material -- and it has been since the day it dried. Because of this, it is going to take moisture from the ground outdoors, slowly releasing some of this moisture into your home. This really is most significant reasons that cellars are notoriously damp, humid spaces.
As this moisture passes through your concrete, it brings a small percentage of minerals from the soil outside the house in conjunction with it, combined with the lime in the cement itself. When it evaporates in your basement, it leaves these types of minerals behind. With time, they create the white-colored, flaky dust that you see on your wall surfaces right now.
Cleaning Efflorescence from Basement Walls
There are several products currently available that are especially designed for removing stains from cement walls and flooring. One great way to get rid of efflorescence will be to rent a pressure washer from a local home improvement store and to combine it with these chemicals to effectively blast efflorescence away from the concrete.
For a more economical solution, however, you could substitute these customized chemicals with a solution of bleach. Combined with a power washer, pressure washer, or simply by applying with a scrub broom and some work, you ought to be in the position to clean off most efflorescence challenges.
Phosphoric acid may also be used to not only eliminate efflorescence powder but also corrosion, grime, unsightly stains, and hard water deposits. Even so, phosphoric acid, along with other chemicals, must be used very carefully and with great attention.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete areas from efflorescence before a problem arises. Having said that, if you clean already damaged concrete, protection can be applied after.

This barrier stops the movement of moisture through the basement walls and floors, protecting your basement from both efflorescence and also the water vapor transmission linked to basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, or any other ways, and it cures in 2-4 hrs. It is safe for indoor use in addition to outdoor usage, and can protect your basement in a number of ways.
