Evo-Stik Evoset Frostproofer is designed to accelerate the setting of mortar mixes year round but particularly in cold weather and during the Winter months. Suitable for use where calcium chloride accelerators are not permitted and is ideal for bricklaying, rendering and blockwork. Evo-Stik Evoset plasticises the mix to improve its workability and frost resistance making it suitable for mortars and non-structural concrete with embedded metals.
