It is CE approved and should be added directly to the gauging water at a rate of 500ml (half a bottle) per -
£3.65 - £12.95 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. To apply as a primer, shakSelect options This product has multiple variants. The options may be chosen on the product page -
£7.42 ex. VATA range of easy-to-use, chloride-free cement colourants made with high-quality oxide pigments for permanently coloring mortars, cement, concrete, and renderings. The pigment disperses easily for uniform shades per batch, with adjustable color depth for varied tones. CE Approved, the dye should be pre-mixed into the dry sand/cement mixture before adding water. For accurate color matching, always weigh the cement dye and cement rather than gauging by volume, and reduce dye for lighter shades. Key Points: Formulated for easy incorporation into the mix.

£10.64 - £105.13 ex. VATSBR Admixture is a styrene-butadiene copolymer latex that enhances the flexibility of cement screeds and mortars, improving their water, chemical, and abrasion resistance, as well as their durability. It is ideal for both internal and external floors and renderings in areas subject to continual or intermittent water and chemical exposure. The product acts as an excellent waterproofing admixture, improving adhesion and reducing shrinkage and cracking in floor screeds, and is perfect as a bonding agent for new-to-old concrete. It can be used as a bonding agent, admixture, or general-pSelect options This product has multiple variants. The options may be chosen on the product page -
£4.96 - £23.11 ex. VATBond It Frostproofer & Hardener is a high-performance building chemical that enhances frost resistance and accelerates cement setting by improving hydration. Specially designed for bricklaying and rendering in low and sub-zero temperatures, it increases workability, strength gain, and water resistance while allowing up to a 15% reduction in gauging water. The non-corrosive, chloride-free formulation ensures it does not degrade steelwork or wall ties. CE-approved, it also reduces curing time and shrinkage, with hot water recommended below 4°C and usage discouraged below 2°C if tSelect options This product has multiple variants.

£4.47 - £107.12 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.

£3.14 - £15.37 ex. VATBond It Liquid Mortar Plasticiser is a chemically balanced plasticiser based on synthetic air-entraining agents, designed to enhance the workability of bricklaying and plastering mortars while increasing resistance to freeze-thaw cycles. It eliminates the need for additional lime, reducing the risk of cracking and crazing. Suitable for use in brick mortars, cement renders, and pointing mixes, it ensures a smoother, more durable finish. Simply add 100-150ml per 25kg bag of cement to gauging water for best results. Also available on request in the original wood resin blend (brown). CESelect options This product has multiple variants. The options may be chosen on the product page -
£5.71 ex. VATEVERBUILD OPTI-MIX 3-IN-1 RENDER ADDITIVE is a highly concentrated, triple-action formula designed to enhance the performance of render mixes. 25 times stronger than conventional render additives, it acts as a waterproofer, air-entraining plasticiser, and open-time extender, eliminating the need for separate admixtures. The additive forms stable air bubbles in the mix, improving workability for a smoother, “buttery” consistency while preventing shrinkage, cracking, crazing, and frost damage. It also reduces water absorption, minimizes efflorescence, and enhances resistance to fre -
£5.89 ex. VATEVERBUILD OPTI-MIX INTEGRAL WATERPROOFER is a versatile, all-in-one solution that functions as a plasticiser, waterproofing agent, and salt inhibitor. This concentrated formula is easy to use and ensures consistent results with no waste, providing 25 times the coverage of standard waterproofers (1L = 25L of standard waterproofer). It improves the water resistance of mortars, enhances workability, and offers protection against freeze/thaw cycles, making it an ideal choice for construction projects. Key Points: Improves Water Resistance – Boosts the water resistance -
£1.83 - £50.05 ex. VATEVERBUILD 501 Universal PVA Bond is a versatile, medium-viscosity bonding agent and adhesive, specially formulated for the building industry.
