An efflorescence-curing liquid additive for cement and masonry mixtures that permanently stops both primary and secondary efflorescence. Guaranteed. Use in concrete, masonry, brick, block, mortar, pre-cast and poured-in-place concrete. For best results, mix into the (batch) water before mixing with cement.

• Concrete, masonry, brick, block, stone, stucco, poured-in-place, pre-cast and any other cementations products
• Great for use in virtually all concrete mixes
• Recommended to be incorporated by ready-mix plants, architectural block, concrete roof tile and paver manufacturers, makers of integral pigments, and other specialty mortar, micro-topping and overlay manufacturers

"NewLook’s EFFLOCK™ is an chemically engineered water-based solution containing nano-binding composites that react with impurities such as calcium and mineral based salt that can be found in mortar mixes, cement products and aggregates. This reaction binds these impurities permanently and prevents efflorescence salt from leaching out to the surface. The nanotechnology of EFFLOCK’s chemistry is approximately 100,000 times smaller than even the smallest cement particle." -Retrieved 1/2/2015 (see Technical Data Sheet via product link)
