A product based on  fluoropolymers and special additives  in aqueous solution specifically formulated for application on  extremely alkaline substrates.

CALCEFRESH  can be applied as early as about 36 hours after lime application It effectively protects lime-based surfaces and finishes  from damage caused by heavy rains that can indelibly mark the surfaces themselves, especially before the lime has finished its natural carbonation process and has thus become stable. The special formulation allows excellent penetration of the product  into the substrates to be treated,  affecting neither their breathability  nor their chromatic appearance. It also possesses  high resistance to UV rays and weathering.
