Ironstone Mineral Primer
A high-bonding mineral based primer to control high suction backgrounds whilst remaining vapour permeable.
Description
A high-bonding mineral based primer to consolidate problematic surfaces, internally and externally, whilst remaining vapour permeable. Developed in partnership with Heidelberg Materials Socli.
Suitable for lime, silica and clay plasters before applying Ironstone top coat Renders and Plasters.
Ironstone Mineral Primer creates a permanent bond on highly absorbent and low-pore, smooth, or organically modified substrates. The primer’s gritty texture creates a key for a new plaster or render to bond to.
Benefits:
- High adhesion on smooth and porous substrate
- Grippy grain texture with 0.4 mm texture grain
- Evens out differing absorption and texture defects
- Highly alkaline-resistant
- Solvent-free
