FAQ

What is skimming plaster used for?

A fine, smooth plaster used to skim gypsum board, joints, screw heads and surface imperfections — giving a perfect, paint-ready finish on walls and ceilings.

Do I need to skim the whole wall or just the joints?

Both options are valid. Use jointing plaster to fill joints and cover screws only, or use skimming plaster for a full skim of the entire surface — a full skim gives a superior painted finish.

How much do I need for a 3m x 3m room?

For a full 2-coat skim: 2–3 x 40kg bags. For jointing only: 1 x 20kg bag of jointing plaster. If it’s a small job or touch-up, Metacote is also available in 10kg. Bring your room dimensions and we’ll calculate the exact quantities.

Can I use skimming plaster on old painted walls?

Yes — scrape off any loose or flaking paint, apply bonding liquid as a primer, then skim. The bonding liquid prevents the dry surface from pulling moisture out of the plaster too quickly.

Can I skim over fire board or moisture board?

Yes — both fire board (pink) and moisture board (green) accept skimming plaster directly. Prime the board surface with bonding liquid before applying for best adhesion.

Is skimming plaster the same as cornice adhesive?

No — cornice adhesive is thicker, stickier and sets quickly for bonding cornices. Skimming plaster is finer, smoother and designed for flat finishing. Do not substitute one for the other.
