Biokil Crown Integral Waterproofer - Concentrated Liquid Waterproofing & Plasticising Admixture

Concentrated Liquid Waterproofing & Plasticising Admixture for Mortar, Render & Concrete. A highly concentrated integral waterproofer and plasticiser for use in cementitious mixes. It enhances workability, reduces water permeability, and provides long-term resistance to water ingress—even under freeze/thaw cycles—while maintaining breathability.. Key Benefits. Waterproofs & plasticises mortar, render, screed & concrete. Reduces shrinkage, cracking & bleeding in fresh mixes. Improves freeze/thaw resistance with stable air entrainment :contentReference[oaicite:1]{index=1}. Reduces water absorption & permeability, including under hydrostatic pressure :contentReference[oaicite:2]{index=2}. Air entraining, non-corrosive additive—won’t affect steel reinforcement :contentReference[oaicite:3]{index=3}. Product Details & Coverage. Form: Concentrated liquid admixture. Pack Sizes: 5 L and 25 L. Coverage: Dilute at 1:40 (0.6 L concentrate to 24.4 L water); approx. 2 L gauging solution per 50 kg cement :contentReference[oaicite:4]{index=4}.
