Being familiar with Concrete Efflorescence How It Leads To Ugly Foundation Walls
At Permaseal, we all answer customer questions on concrete problems on a daily basis. Just about the most popular, and most puzzling for home owners, is what they should do once they find layers of white, flaky deposits on their basement walls. This kind of powder is very popular on cement surfaces -- especially in basements and crawl spaces -- and it is referred to as efflorescence.
What Can Cause Efflorescence?
Cement is a permeable material -- and it has been since the day it dried. As a result, it's going to take moisture from the soil outdoors, steadily releasing some of this moisture into your dwelling. This really is most significant reasons that basements are notoriously damp, humid areas.
As this moisture moves through your cement, it brings a small portion of minerals from the soil outdoors along with it, along with the lime in the concrete itself. When it evaporates into your cellar, it leaves these minerals behind. With time, they create the white, flaky dust that you notice on your walls right now.
Cleaning Efflorescence from Basement Walls
There are several products currently available that are exclusively aimed at getting rid of stains from cement walls and flooring. One great way to get rid of efflorescence is to rent a power washer from a local home improvement store and to combine it with these chemicals to effectively blast efflorescence off the concrete.
For a more economical solution, however, you could substitute these customized chemical substances using a solution of bleach. Combined with a power washer, pressure washer, or just by applying with a scrub brush and some hard work, you will be able to thoroughly clean off the majority of efflorescence problems.
Phosphoric acid could also be used not only to remove efflorescence powder but also rust, grime, stains, and hard water build up. However, phosphoric acid, as well as other chemicals, must be used cautiously and with great attention.
Safeguarding Your Basement from Efflorescence
At Permaseal, we suggest protecting your concrete types of surface from efflorescence before an issue comes up. However, if you thoroughly clean already damaged concrete, protection can be applied afterward.
Our suggested way to prevent efflorescence is by sealing your cement walls with a cement sealer. This product works deep in the pores of your concrete walls and floors to create a glass-like silicate bond in the cement.
This barrier halts the movement of moisture through the basement walls and flooring surfaces, protecting your cellar from both efflorescence and the water vapor transmission associated with basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it dries out in 2-4 hrs. It is harmless for indoor use in addition to external use, and can protect your basement in several ways.
