£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.

£2.85 - £85.57 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

£7.60 ex. VATSika MaxMix® Waterproofer is a highly concentrated waterproofing and air-entraining admixture for sand and cement mixes, delivering improved workability, enhanced water resistance, and long-term protection against shrinkage, cracking, and freeze/thaw damage. Sika MaxMix® Waterproofer forms extremely stable air bubbles in sand/cement mixes. Its concentrated formula means 1 litre provides the equivalent performance of 25 litres of standard waterproofer. Key Points - Improves water resistance and helps reduce efflorescence. - Enhances mortar workability with a smooth, plasticised consisten

£5.14 ex. VATSikaMix Frostproofer and Hardener is a chloride-free admixture designed to accelerate the setting and hardening of mortar, concrete, screeds, and renders. It provides reliable frost protection during the curing period in temperatures as low as -8°C, making it ideal for cold-weather construction. The formulation also enables faster finishing times, improves productivity by optimising mould usage, and can be used as a plugging admixture where rapid setting is required. Being non-corrosive, it is safe for use with metal components such as brick ties. Key Points: - Accelerates setting and har
-
£3.49 ex. VATSikaMix Frostproofer and Plasticiser is a chloride-free, air-entraining mortar admixture that combines frost protection, acceleration, and plasticising properties in a single product. Designed for use in cold weather, it improves mortar workability, speeds up finishing times, and enhances resistance to freeze/thaw cycles while reducing cracking, shrinkage, and efflorescence. Key Points - Provides frost protection and freeze/thaw resistance down to -8°C. - Improves mortar workability, trowelability, and ease of brick alignment. - Reduces shrinkage, cracking, bleeding, and efflorescence.

£61.48 ex. VATThe addition of ARDEX E25 Mortar Admix to ARDEX subfloor smoothing compounds is recommended for applications requiring high abrasion or point load resistance, such as temporary wearing surfaces or when applying floor paint or coatings (with compatibility testing and trial applications). It is also ideal for floors with underfloor heating, ensuring the heating is off for 48 hours before and after screeding and then gradually brought up to temperature. Additionally, ARDEX E25 is used with ARDEX K 15 Rapid Drying Self-Levelling Compound to enhance strength and durability, particularly w
