Opti-Mix Integral Waterproofer Available From Greengates Builders Merchants Accrington, Lancashire

OPTI-MIX INTEGRAL WATERPROOFER is a highly concentrated water­pro­ofing and air entraining admixture for sand and cement which is 25 times the strength of conventional products.

OPTI-MIX INTEGRAL WATERPROOFER forms extremely stable air bubbles in sand/cement mixes. This improves the workability of mortar/­render giving it a “buttery” consistency and helps prevent shrinkage, cracking, crazing and mild frost damage during the curing process, as well as providing long term resistance to freeze/thaw cycles, it also contains pore blocking additives to reduce water absorption and reduces the chance of efflo­res­cence (salt formation). OPTI-MIX INTEGRAL WATERPROOFER extends open time to enable large areas to be covered in one go.
