Joint Compounds & Adhesives – Clean Joints, Lasting Strength

Finishing plasterboard walls and ceilings to a high standard begins with the right jointing and adhesive products. At Blacktown Building Supplies, we stock a full range of joint compounds, finishing compounds, cornice adhesives, casting plaster and stud adhesives, suited to both new construction and renovation work.

From base coats to finishing layers, our range helps you achieve smooth, durable results—whether you’re installing plasterboard, fixing cornices, or levelling walls. With trade-trusted options from Knauf and CSR, you can count on quality performance and compatibility across your interior build.

Solutions for Every Stage of the Plasterboard Process

Whether you’re bedding joints, skimming over imperfections, or adhering cornices and studs, our product selection supports every phase of plasterboard installation.

Choose from:

• Base Cote 45 in both 10kg and 20kg for quick-setting base layers
• Final Cote and LiteFinish for smooth, paint-ready top coats

• Casting Plaster and Masonry Adhesives for specialised repair and bonding

All products are designed for easy application, reliable strength, and a professional finish.

Alongside jointing compounds and adhesives, it’s important to use the right accessories to complete your project. Our Plasterboard Accessories section includes everything from paper tapes to corner beads and sanding tools, helping you streamline your workflow and maintain quality from the first coat to the final polish.
