Everbuild Opti-Rend 3-in-1 Render Additive 1L

Everbuild Opti-Rend 3-in-1 Render Additive is a highly concentrated render additive that is 25% stronger than conventional render additives. Our Render Additive saves you both time and money by working as a waterproofer, air entraining plasticiser and an open-time extender so there's no need for separate waterproofing and plasticising admixtures. The workability of the substrate is improved as a result of highly stable air bubbles being formed.

These improve the workability and consistency by helping to prevent shrinking and cracking. It will also provide long-term protection against the freeze/thaw cycle. Pore blocking additives work to reduce water absorption and also the salt formation while also extending the open time, allowing large areas to be completed in one go.
