British Gypsum Thistle Multi Finish Plaster 25kg

British Gypsum Thistle MultiFinish Plaster 25kg

Plasterboard on its own isn’t a wall. Undercoat plaster without a finish coat isn’t a wall. This is what makes it a wall — the finish coat that covers everything else and gives you a surface you can actually live with. Pre-mixed gypsum, 2mm application, and it produces a smooth finish that doesn’t scream “freshly plastered” or look utilitarian or raw.

Works on plasterboard directly, works over undercoat, works on concrete, works on surfaces treated with bonding agent. Versatile in a straightforward way — not trying to do anything fancy, just reliably finishing walls and ceilings the way they’re supposed to be finished.

Specs, straight up

Pre-mixed gypsum finishing plaster, 25kg bag, pink. 2mm application, ~1.5 hour setting, works on plasterboard and undercoat backgrounds.

Where it gets used

Last coat on walls and ceilings in homes, offices, commercial buildings — anywhere there’s plasterboard or undercoat that needs finishing before decoration. Professional plastering work, renovation projects, refurbishment, interior construction where the surface needs to look finished instead of raw.

Mix about 11.5 litres of clean water per 25kg bag. Add the plaster gradually while mixing — don’t dump it in all at once. Apply 2mm finish, let it set, sand lightly if needed, then paint or paper. The smoother you get it the easier the decoration is afterward.

Why this product

A finish coat sounds simple until you’re trying to get it smooth and you’ve got plaster that won’t cooperate. This one does — pre-mixed so the formulation’s consistent every time, good workability so it applies properly, reliable setting so you’re not waiting half the day. Works with plasterboard directly which saves time if you don’t need an undercoat. Works over undercoat if you do. Produces a surface that looks finished and ready for decoration instead of raw or textured. 25kg per bag is practical to handle and mix without waste.
