One tub that does the taping coat, the finishing coat and the patch-up on a plasterboard wall, so a small repair doesn't mean buying three different products.

GSA's own instructions are to bed the joint with jointing tape and a thin coat on a 100mm knife, let it dry for 24 hours, then fill level on a 150mm knife and finish with a wide feathered coat on a 200mm knife. Once it's had about 24 hours it sands back smooth with 150 grit, and it takes paint. It also works as a top coat over a base coat if you've already done your bedding, and it's handy for filling cracks and holes.

The 1.5kg tub suits a repair or a room rather than a whole house, and it cleans up with water. Full specs are in the tabs below, and if you're not sure what your wall needs, call us on (08) 8536 4333 or come in and chat with us at 34-52 Milnes Rd, Strathalbyn.
