25kg Thistle Bonding Plaster

The 25kg Thistle Bonding Coat Plaster is a high-performance undercoat plaster designed for use on a wide range of backgrounds, including low-suction surfaces such as concrete, plasterboard, and painted walls. Manufactured by British Gypsum, this versatile bonding plaster provides a smooth, level base ready for skim finishing, ensuring a professional-quality surface every time.

Product Features/Specifications:

This lightweight pink undercoat plaster offers excellent adhesion and workability, making it ideal for both new construction and renovation projects. It can be applied by hand or machine, bonding securely to most internal surfaces that do not readily absorb moisture.

Detailed Product Benefits:

Thistle Bonding Coat is specially formulated with fine aggregates to enhance coverage and ensure a consistent, even finish. Its superior adhesive properties eliminate the need for mechanical keying on low-suction backgrounds. The controlled set time provides flexibility during application, allowing plasterers to achieve a seamless surface before final finishing with Thistle Multi-Finish or similar topcoats.

When fully cured, it delivers a durable and stable underlayer that resists cracking, shrinkage, and surface imperfections, ensuring long-lasting results.
