New Concrete Admixture Puts an End to Efflorescence
EffLock from NewLook International permanently stops efflorescence by binding with sodium-based impurities within the concrete. Only about 8 to 10 ounces of the liquid admixture are needed per 100 pounds of cement.
Nothing ruins the beauty of decorative colored concrete more than efflorescence, that ugly, white powdery substance that can form on concrete slabs when water-soluble salts migrate to the surface. Sealing the concrete can help prevent the problem by blocking moisture penetration, but sometimes it's not enough.
The EffLock efflorescence-curing system from NewLook International does more than just seal the concrete. It works from within, using nano-fusion technology to react and permanently bind with sodium-based impurities in concrete to prevent efflorescence from forming. EffLock’s nano-chemistry is 100,000 times smaller than the smallest cement particle, so the product actually passes through and becomes part of the cement or sand it reacts with.
“While other products try to minimize water intrusion, EffLock uses the presence of water to its advantage,” says NewLook vice president Jacob Webb. EffLock reacts when hydrogen is present, so it needs water for activation. It stops reacting when the concrete mixture dries out. Webb claims it will continue to react each time the concrete gets wet, which prevents the formation of efflorescence for the life of the concrete.
EffLock is also said to improve the performance of concrete densifiers and penetrating sealers.
It binds contaminants and other salt-based minerals in the concrete that can inhibit a sealer's ability to absorb and react. “The overall quality of concrete is tremendously improved when treated with EffLock," says Webb. "The cosmetic appearance is improved as the concrete cures, resulting in a more uniform finish. And fewer air pockets and pinholes appear during the finishing process.”
EffLock can be used with all cement types and admixtures. Cure-and-seal products can also be used on treated concrete. It is available in liquid or powder admixture form and as a topical treatment for existing concrete. An efflorescence remover to clean off existing surfaces is also available.
