Param Micro50

self-leveling micro underlayment

Param micro50 is a self-leveling micro underlayment formulated using very latest cement-polymer technology that allows to be very fluid (anywhere between 30%–40%) as compared to any conventional premium self-leveling concrete toppings. It is designed for interior applications where a super smooth surface is desired. Concrete overlays or micro-toppings or other hard surface flooring coverings such as ceramic tiles, porcelain tiles or natural stone can be applied within 6–8 hours after application. Flexible floor coverings such as carpet, VCT, rubber and engineered wood plank can be installed in as little as 16–18 hours.
