Palace Chemicals Fast Flex is a polymer-modified, cement-based, protein-free, sub-floor smoothing underlayment, giving a consistently level screed up to 30mm thick. Fast Flex incorporates specially blended cements, graded sands, built-in polymer, anti-shrink agents and organic super-plasticisers, which when mixed with water give the ideal properties for application over a comprehensive range of floor surfaces such as tamped or worn concrete and sand/cement floor screeds, plywood and dense impermeable surfaces. It is also suitable for heated sub floors. Palace Chemicals Fast Flex will give improved adhesion to all types of substrate and provide enhanced abrasion and point-load resistance. This product is not suitable for external application.
Palace Chemicals Fast Flex when applied over a smooth even non-absorbent floor at an average 3mm depth will cover at a rate of one 20kg bag per 5.0M². Adequate ventilation is essential during the drying process and any draughts or exposure to excessive heat sources must be eliminated to ensure consistent drying.
Palace Chemicals Fast Flex when applied at 20°C & 65% RH under ideal site conditions will allow for a working time of up to 20 minutes and then reach the initial set after 1 hour. Under
the above conditions it will rapidly cure to allow light foot traffic after 3 hours and will be ready to receive tiles after 4 hours and soft flooring after 24 hours.
Palace Chemicals Fast Flex is supplied in 20kg moisture resistant bags and should have a storage life of not less than 12 months if stored in dry, un-opened and frost-free conditions.
