Renderproof Render Additive is a salt and water resistant admixture. Dilute it for use in sand and cement renders. Use the mixture to plaster walls after treating rising dampness.

What does a Render Additive do?

  • Moisture evaporates after rising damp treatments. A waterproofer helps to hold it back as the walls dry.
  • As water evaporates, salts remain. An inhibitor helps to stop salt transfer to the plaster surface.
  • A plasticiser improves the render's workability.

Use triple-action Renderproof Render Additive in plaster mixes. It removes the need for separate admixtures. Add one part of Renderproof to 24 parts water. Use the 25 litres of diluted fluid with 50 kg of cement in a 3 to 1 sand-to-cement mix. Use our lightweight Renovating Plaster if you need a less dense render coat.
