Features and benefits for specifiers and clients

• Range of finishes for grip and aesthetics : A range of different finishes can be achieved using textured coatings, quartz aggregate, chips or a surfacing aggregate. Textured coatings provide long-term good grip both on parking areas and access stairs. The application of a self-levelling PMMA-based mortar increases the amount of mechanical stress that the system is able to withstand.

• Ultimate design flexibility : Apart from the standard range of colours, almost any RAL colour can be provided with no minimum purchase, subject to the minimum 10kg package size. Also, special formulations (eg, with modified viscosity) can be supplied for specific projects, if required. The finishing coats are UV resistant.

• Range of guarantees: our systems are guaranteed up to 20 years, depending on the number of resin layers used, and are covered by our insurance-backed Sopracover Warranty Scheme.
• Reinforced systems substrate cracks bridged: The PMMA resin technology, in conjunction with a polyester embedded reinforcement fleece, gives the Alsan systems the flexibility to ensures that any cracks in the substrate that might appear in the future will be safely bridged.
