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

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.

Areas For Use:

  • External renders.
  • External pointing.
  • Structures below ground level.
  • Pool and tank linings


Add Optimix Integral Waterproofer to a 10 bucket of water and stir/mix well. Dry mix all other ingredients and add sufficient quantities of water/­Optimix Integral Waterproofer solution until the desired consistency is achieved. Never add this product directly to the dry mix, always let down into a portion of gauging water.

  • Do not exceed recommended dosage rate range and DO NOT overmix.

  • Selection of correct materials and mix design relative to the substrate and exposure levels are of paramount importance.
