What this product is for
Thistle Bonding Coat is a base coat plaster for internal walls and ceilings.

Common substrates include concrete, ceramic tiling, plasterboard and surfaces pre-treated with Thistle Bond-it primer.

Compatibility and surface preparation
Thistle Bonding Coat bonds effectively to concrete, plasterboard, ceramic tiles and pre-primed surfaces. Before application, ensure the background is clean, free from dust, loose material and contaminants. Low suction surfaces such as concrete and tiles may require treatment with Thistle Bond-it to improve adhesion and control suction rates. Always check that the substrate is structurally sound and stable.
