  • For filling large static cracks and deep holes
  • For making good and filling electrical wall chases
  • Can facilitate ‘dot and dab’ plaster board to walls
  • For smoothing and plastering raw masonry, concrete, aerated concrete, lightweight building boards, softboards and insulation boards

The extra fine formulation can help to achieve a feather edge, ideal for achieving a high quality, smooth finish. It is tension free with a non-shrink formulation and even at very thin bed depths, the product creates a hard, crack free sound surface which is not affected by wallpaper adhesives, water or solvent based paints.
