- ›Let plaster dry fully before painting or it will peel.
What a plasterer does
Plasterers skim existing walls and ceilings, float and set bare masonry, dry-line with plasterboard, and render external walls. A good plasterer leaves a flat, smooth surface ready for decoration. Skimming is a thin coat over board or sound existing plaster; a full float and set is two coats over brick or block.

Questions to ask and common mistakes
Ask whether the price includes board and materials and how long it will take to dry. Common mistakes: painting before the plaster is dry, booking second-fix carpentry before the plaster is done, and leaving furniture in the room.
- ☐Does the quote include board, beads and materials?
- ☐How long will it take to dry before decorating?
- ☐Will you clean up and remove waste?
- ☐Can I see a recently finished room?
Frequently asked
Skim or board and skim?
If walls are sound and flat, skim. If they are badly damaged or uneven, over-board with plasterboard then skim — faster and flatter.
