Thistle Bonding Coat Plaster 25kg

Thistle Bonding Coat Plaster is a gypsum-based undercoat (base) plaster made by British Gypsum. It’s designed to be used on a variety of surfaces including low-suction backgrounds like concrete and masonry, as well as plasterboard. Thistle Bonding Coat is particularly useful in drywalling situations where levelling is needed before skim finishing. It improves adhesion on surfaces where standard base plasters struggle and leaves a durable, impact-resistant undercoat that helps prevent cracking and delamination. Thistle Bonding Coat comes as a fine pink powder in 25kg bags, which can be mixed with water to the needed consistency.
