£5.35 ex. VATThis premium quality, non-corrosive, 5-times stronger concentrate additive is designed to increase frost resistance and accelerate the setting time of cements by improving hydration rates. It is specially developed for bricklaying and rendering in low and sub-zero temperatures, enhancing workability, strength gain, and resistance to water penetration. The additive will not degrade steel wall ties, reinforcements, or other steel items, making it safe for use with metal structures. It is CE approved and should be added directly to the gauging water at a rate of 500ml (half a bottle) per

£4.37 - £19.42 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.

£7.11 ex. VATSika MaxMix® Concentrated Accelerator & Frostproofer is a chloride-free, air-entraining admixture designed to accelerate the setting and hardening of mortars and renders. Formulated for cold-weather construction, it provides frost protection at temperatures down to -4°C while eliminating the need for a separate frostproofing additive. The product improves workability, reduces water absorption and penetration, and is safe for use with embedded metal components such as brick ties and reinforcement. Its concentrated formula delivers economical performance, with 1 litre treating up to 100 kg of

£54.51 ex. VATThe use of ARDEX E 25 Mortar Admix in conjunction with ARDEX sub-floor smoothing compounds is advisable in specific situations: when high abrasion or point load resistance is necessary, for temporary wearing surfaces, when a floor paint or thick coating will be applied later (ensure compatibility and conduct a trial application), and when the floor has underfloor heating. For floors with underfloor heating, it is essential to turn off the heating for 48 hours before applying the screed, leave it off for another 48 hours after application, and then gradually increase the temperature.

£22.24 - £1,112.24 ex. VATTopcem is a specialized hydraulic binder that, when combined with graded aggregates and water, creates mortars that harden in about 24 hours and dry within approximately 4 days. It is ideal for forming bonded, unbonded, and floating screeds on both new and existing concrete surfaces, facilitating the quick installation of various flooring materials, including PVC, linoleum, ceramic tiles, natural stone, carpet, or timber. Topcem is suitable for both indoor and outdoor applications, making it a versatile choice for projects that require rapid drying times. Key Points:Select options This product has multiple variants.
