Sandex is a high build, multi-coloured, protective coating consisting of coloured quartz aggregates embedded in a clear, 100% acrylic resin. It is one of the coatings in the family of the Durex® Architectural Wall Coatings.
- Exceptional durability.
- Excellent water repellency; protects surfaces from moisture penetration.
- Breathable coating; allows water vapour within the wall system to evaporate.
- Excellent adhesion to substrate.
- Colourfast, not affected by ultra-violets rays.
Sandex is used as an effective long wearing protective coating over all types of solid substrates. Sandex is mixed to match selected colours.
