Cornerstone Wintermix is a dry ready mixed multipurpose natural hydraulic lime mortar, render and plaster formulated explicitly for work in challenging cold environmental conditions. Available in the colour off-white.

Engineered with precision, using 100% pure natural hydraulic lime, natural sands, and additives to create a high-performance winter work multipurpose mortar, render and plaster. With improved workability, an accelerated set, and an enhanced cure, this mortar is designed explicitly to combat frost damage and limit the impact of frost crystals. Once the initial strength is achieved, strength development slows in line with a standard NHL mortar. Free of synthetic polymers and Portland Cement. Available as standard with Otterbein NHL2 or Saint-Astier® NHL3.5. Other binders and mix ratios are available upon request.

Well-suited for winter work applications which require additional support to combat the risks associated with winter work in challenging conditions.
