Efflorescence Control

Efflorescence Control  by Redimere Surface Solutions

Efflorescence is a common problem seen with concrete flooring. Efflorescence is the white powdery substance on the surfaces of unsealed concrete and the white blush seen with sealed floors. It is caused by vapor migrating through the slab bringing soluble salts to the surface of the concrete.

There are some efflorescence reducing measures that can be taken. Without these, you will surely have some degree of efflorescence occurring. You need an experienced concrete contractor like Redimere Surface Solutions, which will install the proper site surface drainage, mix a well graded concrete with a water reducer to minimize paste, and concrete that is well consolidated.

If you already have efflorescence on your concrete, no need to worry. There are a few tests such as the Plastic Sheet Test and the Calcium Chloride Test that can help determine the source and the rate of vapor transmission before prescribing a remedy. Most common solutions in stubborn efflorescence cases are light sandblasting or even a mild acid rinse to wash off on unsealed concrete surfaces.
