A Skim Coat is a thin layer 1-6 mm of cementitious plaster which is “Skimmed” , e.g. applied very thinly onto interior and exterior of plustered and concrete surfaces. Skim Coats can be applied to concrete, light weight concrete, blockwork and rendered surface.
- Improved surface durability; no cracking
- Improved bonding to the base coat
- Covering of pin holes and surface unevenness
- Excellent weathering resistance
- Excellent, smooth or sanded surface finishes
- Reduce paint consumption
The substrate must be clean and free from loose particles, dirt, grease and traces of foreign material. For loose plaster areas, remove any defective materials and re-plaster the area. If the job site is hot or windy, dampen dry surfaces before application.
Proportion of Mixin
Skim Coat Sanded 3.4 kg per water 1 liter or Skim Coat Sanded 2.7-3 part: Water 1 part (by volume)
1.3 kg / 1 sq.m (Thickness 1 mm.)
Using a steel trowel, apply Skim Coat evenly to the desired thickness. If it necessary to increase the thickness of Skim Coat, apply a second coat after the first has set (approx. 15-45 min). Skim Coat Smooth thickness varies from 1-6 mm. The surface should be smoothed with steel trowel. Sanding may be used to obtain an even higher degree of smoothness. Once Skim Coat has dried, a final coat such as a sealer and decorative paint may be applied.
