British Gypsum Thistle Bonding Coat Plaster


British Gypsum Thistle Bonding Coat Plaster is a versatile undercoat plaster that can be used on smooth or low suction backgrounds such as tiling, concrete, plasterboard or surfaces treated with Thistle Bond-it (a bonding agent used to pre-treat smooth and/or low suction backgrounds). 

At its core, this lightweight, retarded hemihydrate is a pre-mixed gypsum plaster that comprises exfoliated vermiculite aggregate and only requires the incorporation of clean water to prepare it for application. 

Thistle Bonding Coat Plaster boasts a fine mix that ensures improved workability - rendering it hassle-free when it comes to spreading, ruling and Darbying. Thistle BondingCoat makes for a smooth surface on internal walls and ceilings, as well as serving as a substantial base for a range of decorative finishes. Although, it's important to note, that pre-treatment is required for painted surfaces.

  • Durable base for decorative finishes

  • Undercoat plaster for low suction surfaces

  • Suitable for new walls/ the renewal of old walls

  • Applies directly to plasterboard where dubbing out is required

  • A hard-wearing base coat for Thistle finishing plasters

Frequently Asked Thistle Plaster Questions

How Thick Should Plaster Be Applied? 


Undercoat plasters are typically 11mm and the majority of finish coat plasters are 2mm thick.

How To Store Thistle Plaster? 


Bags should be stored in a dry environment, away from moisture - water exposure can result in lumps forming within the mix.


If you plan on storing the bags on a concrete floor, we advise that you use dry timber platforms to elevate the bags away from the potentiality of moisture. 

Can Tiles Be Directly Applied to Thistle Plaster? 


Yes, tiles up to 20kg/m2 can be applied directly to the Thistle finish. If your aim is to provide a background for tiles, ensure you don't polish the surface beforehand. Should the surface already be polished, you should make sure to roughen this and make use of a suitable primer.
