Fassa Base Coats for Lightweight Block / High Suction Backgrounds
Fassa Bortolo base coats or primers recommended for use on lightweight blockwork. Lightweight blocks tend to have high suction characteristics and they are low in strength so it is advised to only apply render finish coats after the application of a primer or a base coat.
Fassa SP22 is a high-performance cement-based rendering mortar designed for use as a bonding undercoat on brickwork and concrete substrates. Suitable for both internal and external applications, it provides a reliable base for subsequent plaster or render finishes.
