How do you paint new plaster?

Paint new plaster only when the plasterer says it is dry, the dust is off, and you follow the tin for a bare plaster surface rather than for a wall that has been painted before. This guide is that order of work, and it does not print a thinning recipe.

What is this guide for?

Setting up a skim is the plasterer's sequence. This guide starts when that plaster is on the wall and someone wants to decorate it. It is not a guide to skimming, and it is not a guide to old painted walls.

A new skim in Crewe, a replastered chimney breast in Nantwich or a patched ceiling in Sandbach still needs the same question: is this surface actually ready for paint? The drying question is the same on a Cheshire wall as on any other. Anyone in the UK can post the decorating job.

The word latex on a tin is about labels. White ceiling paint is about choosing a ceiling finish on a ceiling that is already a painting surface. Neither of those is the first coat on bare plaster.

How do you know the plaster is ready?

Do not invent a calendar. Ask the person who put the plaster on.

  • The colour of the plaster often goes from dark and damp to pale and even. That is a clue, not a rule this guide can time.
  • A wall that still feels cold and clammy in one patch is not ready, even if the rest looks pale.
  • Closed windows and a heater blasted at the wall can dry the face and leave the back damp. Ask the plasterer about ventilation before you turn anything up.
  • Dust on the surface should be brushed or wiped off when they say the wall can be touched. Paint sticks to dust, then the dust sticks to nothing.

If the job was a skim over a textured coating, this guide is the wrong one until that coating has been dealt with by someone trained for it. Textured ceilings is that subject. Do not sand a textured ceiling to make it ready for paint.

What should the first coat be?

This is the part people want a ratio for. This guide refuses one. Tins differ, and a ratio copied from a forum is how a wall flashes.

What you can say, without a number:

  • New plaster sucks moisture out of the first coat. If you put a full finish coat straight on, it can dry in patches and look shiny in some places and flat in others.
  • A thin first coat is the usual decorator's answer. Whether it is a primer, a thinned emulsion, or a product sold for new plaster is a question for the tin and for the decorator.
  • The regulations define primers as coatings with sealing or blocking properties designed for use on wood or on walls and ceilings [S1]. They define matt coatings for interior walls and ceilings as coatings designed for those indoor surfaces [S1]. Your tin should say which it is. If it says neither, do not guess.
  • VOC content, if you are comparing tins, is the mass of volatile organic compounds in grams per litre in the product ready to use. Compounds that react during drying and become part of the coating are not part of that content [S2].

Write the product name into the quote so two decorators are not pricing two different first coats.

How do you work on a wall you can reach from the floor?

For a wall you can reach while standing on the floor, the order is simple. This is not a stairwell method.

  1. Clear the floor and the skirtings. New plaster marks everything it touches, and so does paint.
  2. Confirm with the plasterer that the surface is ready.
  3. Remove dust.
  4. Cut in the edges with the first coat the tin describes. Do not invent a mix.
  5. Roll or brush the open wall with that same first coat.
  6. Leave it for the time the tin describes. This guide does not print that time.
  7. Look at the wall in daylight. Patchy sheen means it was not ready, or the first coat was too heavy. Ask before you pile more paint on.
  8. Apply the finish coats the tin describes, in the finish you actually want to live with.

Keep the room aired. That is ordinary care while a coating dries.

What about a stairwell or a high ceiling?

A landing ceiling is above the floor. HSE says work at height means work in any place where, if precautions were not taken, a person could fall a distance liable to cause personal injury, and that you are working at height if you work above ground or floor level [S3]. The same page says work at height does not include walking up and down a permanent staircase [S3]. Decorating while you are above the floor is the part to hire. The regulations place duties on employers and on those who control the work, such as building owners who may contract others to work at height [S3].

Do not paint a stairwell from a chair. Hire a decorator and ask what they will stand on. HSE: work at height. QuoteZila is not affiliated with this organisation. The sequence above is for walls you can reach from the floor. Our painters and decorators page is the trade, and plasterers are who you call if the plaster itself is wrong.

What should the quote say?

Citizens Advice says to get written quotes, that a quote is a fixed price and an estimate is a rough guess, and that some traders charge for quotes, so ask about this first [S4].

Ask the decorator to write:

  • which rooms are new plaster and which are already painted
  • the product for the first coat, and the product for the finish
  • that they have spoken to you about drying, or that they will check the wall themselves
  • whether ceilings are in the price
  • who protects the floors

A price that says "emulsion throughout" does not say whether new plaster is included.

Jobs you might post

These are examples, not taken from real job posts.

  • "Dining room skimmed last week. Plasterer says ask them about drying. Please quote to decorate walls only, name the first coat, and do not include the ceiling."
  • "Ceiling is new plasterboard and skim, walls are old paint. Please treat the ceiling as new plaster and the walls as already painted."
  • "Stair wall was patched. Please say what access you need. I do not want anyone standing on the stairs without agreeing it."

Posting the decorating

Photos of one wall in daylight help. Up to five matched local businesses can send a quote [QZ2]. QuoteZila is free for customers and local businesses [QZ1].

What else are people asking?

How long should I wait before painting new plaster?

This guide does not print a number of days. Cold rooms and closed windows slow drying. Ask the plasterer what to do with the heating and the windows, and wait until they say the surface is evenly dry. A tin for bare plaster may still say to wait. Follow that tin, not a habit from another house.

What is the first coat for?

New plaster is thirsty. Decorators often put a thin first coat on before the finish coats, so the later coats do not flash and go patchy. This guide does not print how much water to add, or whether to add any. The primer definition in the paint regulations is a coating with sealing or blocking properties designed for wood or for walls and ceilings. Use whatever the tin in your hand tells you to use first.

Can I use the same tin as on the old painted wall?

Only if that tin says it is for new or bare plaster as well as for already painted walls. Matt coatings for interior walls and ceilings are coatings designed for indoor walls and ceilings. That definition does not say they are the first coat on fresh plaster. Read the bare-plaster line before you open the tin you used in the hall last year.

The plaster has a crack. Should I paint it?

A hairline that the plasterer expects can be filled when they tell you the wall is ready. A crack that opens, or a ceiling that sags, is not a painting problem. Ask the plasterer back before any coating goes on. Painting a moving crack just draws a line in the colour.

Does QuoteZila check decorators and plasterers?

No. We don't check insurance, qualifications or registrations, so please check these yourself before you hire. You can report a quote or a business from your job page.

This page is general information, not professional or legal advice. QuoteZila does not check Gas Safe, WaterSafe, NFRC, NICEIC or other registrations against the register on your behalf: look them up yourself.
