Choosing plaster

Undercoat for the background

Hardwall suits high-suction backgrounds like brick and block; bonding suits low-suction backgrounds like concrete or painted surfaces.

Finish coat

Board finish is made for plasterboard; multi-finish suits most undercoats and board.

Fresh stock matters

Old plaster sets fast and unevenly. Order it close to when you need it and keep bags dry.

How it arrives on site

Bags come on a pallet or with a mixed load; keep them dry and off the floor. We agree the drop point and offload method when we price your order. Read more about how delivery works.

How much do you need?

Skimming 25 m² of walls and ceilings at about 2 mm takes around 3 bags of 25 kg finishing plaster, plus angle beads for external corners. Coverage varies with the background, so allow a spare bag.

Plaster & Beads: questions

What is the difference between multi-finish and board finish?

Board finish is designed for skimming plasterboard. Multi-finish works on plasterboard and on undercoat plasters, so it is the more flexible choice.

How much plaster do I need to skim a wall?

A 25 kg bag of finishing plaster covers roughly 10 square metres at a 2 mm skim, but coverage varies with the background and thickness. Check the bag.

Why does my plaster go off too quickly?

Old or damp plaster sets faster. Use bags within their date and store them dry.

Which undercoat for a brick wall?

Hardwall is the usual choice for high-suction backgrounds like brick and blockwork.

Do you sell render?

Yes, sand and cement render materials and bagged renders on request.
