Preparation & Application

Surface Preparation

  • Remove any efflorescence whilst dry using a stiff bristle scrubbing brush.
  • Clean the cracks - remove dust, dirt and all other foreign matter.

Suitable surfaces

  • Brick, mortar, screed, concrete and plaster. Please test other surfaces for suitability.

Mixing

weber.tec Barrier Waterproof Crack Filler should be mixed clean water. Allow mixture to stand for 5 minutes. Remix thoroughly before use.

  • 1.35 litres of clean water per 5 kg bag
  • 0.54 litres of clean water per 2 kg bag
  • 0.27 litres of clean water per 1 kg bag

If weber.tec Barrier Waterproof Crack Filler is used in permanently wet areas where food or cosmetic staining may occur, e.g. kitchens and bathrooms or if increased flexibility is required, the water in the mix should be replaced with a bonding agent (diluted 1 part to 2 parts with water). Mix as above. Note that the crack filler will dry a shade darker. Do not add too much water or attempt to extend the working time by adding more water, as this will cause the set crack filler to be weak with a tendency to crumble. It may also cause surface discolouration and variation, especially with darker colours.

Application

  • Wet cracks, holes and indentations with clean water.
  • Fill the cracks, holes and indentations using a scraper or putty knife.
  • Apply to depth not exceeding 5 mm. For deeper cracks, holes or indentations, apply in 5 mm layer after each layer has been allowed to dry.
  • Even out the weber.tec Barrier Waterproof Crack Filler level with the surrounding surface.
  • Allow to dry for at least 4 hours (drying times may be longer in cold or wet weather) before sanding, drilling or painting. Apply a universal undercoat before painting.
