Delivery detailsChloride-Free Liquid Admixture for Enhanced Mortar Workability
Biokil Crown Mortar Plasticiser is a chloride-free liquid admixture conforming to BS 4887, formulated to improve the workability and durability of bricklaying and rendering mortars. By entraining air into the mix, it enhances frost resistance and reduces the risk of shrinkage and cracking. This admixture is suitable for use in cement, sand-cement, and lime-sand mortars, providing a more cohesive and workable mix.
