OPTI-MIX 3 in 1 RENDER ADDITIVE Available From Greengates Builders Merchants Accrington, Lancashire

Product Description

OPTI-MIX 3 in 1 RENDER ADDITIVE is a highly concentrated render additive which is 25 times the strength of conventional render additives.

OPTI-MIX 3 in 1RENDER ADDITIVE triple action formula acts as a water­proofer, air entraining plasticiser and open time extender which eliminates the need for separate water­pro­ofing/­plasti­cizing admixtures.

OPTI-MIX RENDER ADDITIVE forms extremely stable air bubbles in render mixes. This improves the workability of  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 RENDER ADDITIVE extends open time to enable large areas to be covered in one go. This product is fully tested to the requirements of EN934 Part 3 Table 2
