Before you start

Before you start you will need to consider the following?

  • What is the surface being rendered?
  • What thickness will the render need to be applied for the desired finish?
  • How do you want to apply the render, either by trowel or roller?
  • What sort of finish do you want to achieve either a smooth fine coat or a sandy finish?

Use a Dunlop Multipurpose Acrylic Render as a base coat and then use the Dunlop Multipurpose Fine Coat Render or Dunlop Ready-to-Go Render as a finishing coat.

Handy Hints

  • Keep mixed material out of direct sunlight to extend the pot life of the mix.
  • Never add additional water to reinvigorate a mix, this could result in the render shrinking and cracking.
  • Always wash tools in clean water before the material dries.
