A crucial bonding primer for all CEMHER Microcement and CEMHER Claystone systems. Primer100 creates a residual tack (up to 8 hours) that CEMHER coatings chemically key into, delivering superior adhesion, flexibility and long-term durability on both porous and non-porous substrates.
- Engineered residual tack: forms the bonding interface our systems are designed to grab.
Adhesion & longevity: reduces delamination risk and supports the system’s flexural performance.
System integrity: ensures correct bond to substrate and between layers (with/without mesh).
Do not substitute or omit. Third-party primers are not compatible and can compromise adhesion and system performance.
