Atlas Cerplast Topcoat primer is designed to be used in conjunction with any of our renders.
Increases adhesion – strongly adheres to the substrate and the applied renders.
Limits the absorbability of the substrate – prevents excessive transfer of water from the freshly applied renders into the substrate.
The main characteristics of Atlas Cerplast Topcoat Primer
- ensures ideal adhesion of the render
- reduces absorbability and strengthens the substrate
- facilitates render application and texture forming
- unifies the substrate colour
- can be used as primer ( new tiles on old ones)
- • available in 480 colours
Main properties of Atlas Cerplast Topcoat Primer
Contains aggregate – improves bonding owing to significant broadening of the effective surface between layers (forms rough surface).
Protects substrates against adverse effects of the new coat – forms chemical barrier between substrate and render, limits their interaction – reduces colour penetration from substrates and occurrence of stains on the render surface.
High bonding – min. 1.0 MPa for concrete.
