£3.75 - £18.20 ex. VATAlphaChem Accelerator, Frostproofer & Hardener is a heat‐generating accelerator for cement-based mixes. Its principal uses are to facilitate the production of high early strength concrete, cement render and mortar. It is suitable for use as an aid to cold weather working when the heat generated will offset the retarding effect of low temperatures. AlphaChem Accelerator, Frostproofer & Hardener is based on calcium chloride and surfactants and is therefore not suitable for use in structures that are reinforced with steel. Neither should it be used in mortar in contact withSelect options This product has multiple variants. The options may be chosen on the product page

£3.64 - £12.32 ex. VATA high-performance acrylic dispersion designed for use as both a primer and an additive to enhance the adhesion and flexibility of cement-based tiling products. As a primer, it stabilizes porous and dusting surfaces before tiling, improves adhesion on challenging substrates like vinyl tiles, timber, asphalt, and terrazzo, and prevents swelling in materials such as timber, plasterboard, and MDF. When used as an admixture, it increases the flexibility and bonding strength of adhesives and grouts, making them suitable for areas with slight movement or vibration.

£6.13 ex. VATSikaBond® SBR is a styrene-butadiene co-polymer with versatile applications as an admixture, primer, bonding agent, and sealer in areas exposed to humidity, dampness, or direct water contact. It enhances the water resistance, durability, and flexibility of cement and concrete mixes, making it ideal for renderings, floor screeds, and general bonding or repair works. Containing anti-foam to control mix density, SikaBond® SBR can be used for concrete repair, external rendering, tanking mortars, corrosion protection of steel, silage pit lining, and as a primer or sealer in tiling. It also improv

£51.63 ex. VATARDEX E 100 is an acrylic-based dispersion designed for enhancing screeding and rendering mortars for both internal and external applications. By incorporating ARDEX E 100, the compressive and tensile strengths, elasticity, and bond strength of modified mortars are significantly improved, while workability and plastic properties are enhanced without increasing the water/cement ratio. Additionally, ARDEX E 100 effectively reduces the formation of early-age cracks. It is also suitable for use in bonding slurries and grout mixtures with ARDEX A38 Rapid Hardening and Drying Cement for fl
