£5.04 - £121.77 ex. VATThis high-strength cement waterproofer is ideal for both internal and external applications, including rendering, roof screeds, swimming pools, tanks, retaining walls, basement walls, and reservoirs. It improves the workability and plasticity of concrete and mortar in their wet state, resisting water penetration even under pressure. The product reacts with free lime in the mortar to form hydrophobic crystals, which block the pores and enhance water resistance. For best results, it should be added to the gauging water with minimal water in the mix and a properly balanced cement and sand aggregaSelect options This product has multiple variants.
