Can 600x300mm porcelain tile be fixed to plasterboard wall with ready-mixed adhesive?
Not advisable. Porcelain tiles have extremely low porosity. Ready-mixed adhesives rely on water loss through the joints, background substrate or tile to achieve full bonding. As the tiles have low porosity and joints are reduced due to the large tile size, ready mix products struggle to set. Instead, prime the plasterboard with neat BAL Prime APD or BAL Primer, and then use highly polymer-modified adhesive such as BAL Single Part Flexible or BAL Rapidset Flexible. These set via a chemical reaction.
