What it does
Redispersible polymer powder — spray-dried vinyl acetate / ethylene copolymer that, once redispersed in water, gives cementitious mortars their flexibility, adhesion and deformability.
Typical applications
- C2-grade tile adhesives (flexible)
- EIFS / ETICS adhesive and base coats
- Self-levelling floors
- Tile grouts (CG2)
- Repair mortars and waterproof slurries
