Cornerstone Promix Coarse Basecoat is a dry ready mixed render and plaster designed as a coarse basecoat or float coat within an appropriate render system. Available in the colour white.

Engineered with precision, using 100% pure natural hydraulic lime, natural sands, and conservation-appropriate additives to create a high-performance render and plaster. Enhanced plasticity supports a decreased likelihood of slump and improved adhesion. Further, a longer open time makes this render undemanding to apply, level and finish. Available as standard with Saint-Astier® NHL2 or NHL3.5. Other binders and mix ratios are available upon request.

Well-suited for projects looking for a modern feel or a textured topcoat.

– Conservation appropriate additives
– Vapour permeable to support moisture management
– Features the feel of a modern mortar
– No-fuss levelling and finishing
– Increased water retention with decreased slumping
– Minimised likelihood of shrinkage cracking
– Enhanced workability for those behind the trowel
– Extended working and finishing time
– Promotes even curing for an improved bond
