Paint, laitance and other poorly adhering particles must be removed. Fine hair line cracks must be widened with V groove upto 1 mm minimum and then filled. APPLICATION For filling Sika® Cracksil Acrylic Paste on the cracks of internal or external surface, existing POP or Sika® Wall Decor (wall putty) must be removed till plaster surface is exposed.

Press Sika® Cracksil Acrylic Paste firmly into the crack with a spatula or putty knife and level with the surface. Care must be taken to avoid formation of cavities or bubbles during application.
