Surface preparation

Ensure the existing plaster surface is in reasonable condition, is well consolidated and is not crumbling or coming away from the background. Any loose plaster should be removed, and the surface should be in sound condition before overcoating.

If the existing plaster surface is smooth, consider applying a coat of breathable gritted primer to add a key and provide grip for the new plaster.

Dampen the existing plaster surface by misting or brushing clean water onto the face of the plaster. This helps control suction and ensures a good bond for the new plaster.

Recommended plaster application

  1. Base coat of Universal 2mm.

  2. Top coat of Universal 2mm.

  3. For a smooth finish, moisten the surface of the plaster with a fine mist spray bottle to help polish the surface with a trowel. For more textured finishes, lightly apply a damp sponge.
