Base Coat
Base Coat is a foundational compound used in plasterboard finishing systems. It’s specifically formulated for bedding joint tape, which reinforces the seams between plasterboard sheets and prevents cracking. The base coat also helps build a strong, stable surface for subsequent layers of compound, ensuring a smooth and durable finish. Its adhesive strength and workability make it essential for achieving long-lasting joint integrity and preparing the surface for top coats or decorative finishes

Top Coat
The final layer in a plasterboard finishing system, designed to create a smooth, flawless surface that’s ready for painting or decorative finishes. It’s applied over the base coat and joint tape to conceal any imperfections, feather edges, and ensure a seamless transition between boards. With its fine texture and easy sanding properties, the top coat enhances visual appeal and delivers a clean, professional-grade finish that meets industry standards for interior presentation.

Stud Adhesives
Stud Adhesive is a specially formulated compound used to bond plasterboard sheets directly to timber or metal framing. It provides strong, long-lasting adhesion, ensuring that the boards remain securely fixed and stable over time. Applied in daubs along the studs, it works in conjunction with fasteners to reduce movement, prevent warping, and improve overall wall integrity. Stud adhesive also helps absorb minor irregularities in framing, creating a smoother surface for finishing. Its reliable bonding performance makes it a critical component in achieving a professional, durable plasterboard installation.
