Description

Brush Coat is one of the various exterior textures offered by Durabond Products Ltd. under the trade name of Durex Architectural Coatings. Brush Coat is a high build protective coating 100% acrylic based. It is the most versatile of the Durex Architectural Coatings products. It is primarily roller applied, resulting in a light, uniform, sand textured finish. It can also be applied by brush.

Advantages
  • Exceptional exterior durability.
  • Excellent water repellency, protects wall from moisture penetration.
  • Breathable coating, allows water vapour within the wall system to evaporate.
  • Excellent adhesion to substrate.
  • Abrasion resistant.
  • Colour fast (not affected by ultra violet rays).
  • Heavy duty protective coating.
Uses

Brush Coat in a two coat application is an effective long wearing protective coating for concrete and masonry, for new as well as existing structures. Brush Coat provides a uniform appearance in both colour and texture. Brush Coat in a one coat application is an effective primer for all Durex Architectural Coatings.
