Plaster bonding agents

Plaster bonding agents are used to ensure a strong, reliable bond between new plaster and the surface you’re applying it to. They’re designed to improve adhesion on smooth or low-suction backgrounds, such as concrete, painted walls, or tiles. Traditionally, plasterers relied on roughing up surfaces or using sand-cement slurry for better grip, but modern bonding agents are far more effective and save time.

Whether you’re applying a bonding coat on challenging substrates or preparing a surface for finishing plaster, using the right bonding agent is crucial for a long-lasting, crack-resistant result. Options include adhesive bonding compound that can also be used as a plasterboard adhesive, as well as bonding agents and bonding plaster.

Whether you need a bonding coat for a renovation project or are tackling a new build, choosing the right bond aid for plastering will ensure a smooth and professional finish.

Bonding agents FAQs

What's bonding plaster used for?

Bonding plaster is commonly used as an undercoat to create a stable base on difficult surfaces before skimming with finishing plaster. It provides an even, textured layer that helps the topcoat adhere securely. It’s ideal for low-suction surfaces and can be used on everything from concrete blocks to old painted walls.
