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.
