HP14 Base Coat is a preparation coat for K Rend top coat finishes. HP14 Base Coat can be hand or machine applied. It uses “High Polymer” technology for an enhanced performance onto a wide variety of insulating substrates such as enhanced polystyrene, phenolic and mineral wool. It is designed as the ideal background for thin coat organic resin render such as Silicone TC. Alkali Resistant Reinforcing Mesh should be used in conjunction with HP14 Base Coat at stress points such as door and window reveals.
