Being familiar with Concrete Efflorescence How It Contributes To Unsightly Foundation Walls
At Permaseal, we respond to client questions regarding concrete problems on a daily basis. One of the most frequent, and most puzzling for homeowners, is exactly what they should do when they find layers of white, flaky deposits on their cellar walls. This particular powder is very common on cement types of surface -- particularly in cellars and crawl spaces -- and it is often called efflorescence.
What Can Cause Efflorescence?
Concrete is a permeable material -- and it has been since the day it dried. Because of this, it'll accept moisture from the ground outdoors, steadily releasing some of this moisture into your house. This really is most significant reasons that cellars are infamously damp, humid spaces.
As this moisture passes through your concrete, it brings a little portion of minerals from the earth outside the house along with it, along with the lime in the concrete itself. When it evaporates in your cellar, it leaves these types of minerals behind. With time, they create the white-colored, flaky dust that you observe on your walls right now.
Cleaning up Efflorescence from Basement Walls
There are several products currently available which are specifically geared towards removing stains from cement walls and floors. One good way to remove efflorescence should be to rent a pressure washer from a local home improvement store and to blend it with these kinds of chemicals to successfully blast efflorescence off of the cement.
For a less expensive solution, however, you may substitute these custom chemicals with a solution of chlorine bleach. Combined with a power washer, pressure washer, or simply by applying with a scrub brush and some effort, you will be competent to thoroughly clean off the majority of efflorescence problems.
Phosphoric acid could also be used to not only eliminate efflorescence powder but also corrosion, grime, stains, and hard water deposits. However, phosphoric acid, along with other acids, must be used very carefully and with great care.
Protecting Your Basement from Efflorescence
At Permaseal, we suggest protecting your cement floors from efflorescence before a problem arises. Having said that, if you clean already affected cement, protection can be applied afterward.
Our suggested way to avoid efflorescence is by sealing your concrete walls with a concrete sealer. The product works deep into the pores of your concrete walls and flooring to create a glass-like silicate bond in the concrete.
This barrier puts a stop to the movement of moisture through the basement walls and floors, protecting your basement from both efflorescence and also the water vapor transmission connected with basement humidity.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it cures in 2-4 hrs. It's harmless for inside use in addition to outdoor usage, and can protect your basement in a number of ways.
