Bedroom Celing bumpy

Question

Hello,

We have a bedroom ceiling that is looking bumpy and the finish from the last paint is showing up marks so not a smooth finish.

Paul · Answer

If not flaking sand the bumps with some 80, grit quality sandpaper once smooth apply some diluted ceiling paint  to sanded area once dry recoat whole ceiling maybe twice dry between coats at least 3 hours open windows doors to allow air to flow.

Robert · Answer

You need to sand the surface and peel stop the surface were needed ,fill were needed and apply two coats of paint.

Kashif · Answer

I can take a look at the bedroom ceiling for you. It sounds like it may need sanding, filling, and proper preparation before repainting to achieve a smooth finish.

If a painted ceiling is bumpy with visible roller marks, the fix depends on what's causing the texture:

Light roller texture or paint build-up: Sand the ceiling with 120–180 grit abrasive on a pole sander, remove the dust, then apply two thin coats of quality ceiling paint using a medium-pile roller. Keep a wet edge and avoid over-rolling.

Filler ridges or uneven patches: Sand smooth, apply a finishing filler where needed, sand again, then prime any bare areas before repainting.

Heavy texture or multiple thick coats: Sanding alone may not be enough. Skim the ceiling with finishing plaster or a smoothing compound, let it dry, sand lightly, then mist coat (if needed) and repaint.

Poor previous paint finish: If the last coat was applied unevenly, a thorough sand followed by a high-quality ceiling paint often gives a much smoother result.
If the ceiling feels very rough to the touch or has lots of raised paint, sanding and skimming are usually the best long-term solution.

Common possibilities are:
Poor previous painting – Roller marks, drips, or thick coats of paint can leave an uneven finish. If the ceiling is otherwise flat, it may just need sanding, filling where necessary, priming, and repainting.
Poor plaster finish – If the plaster itself is uneven, no amount of paint will make it look smooth. The ceiling may need a skim coat of finishing plaster before decorating.
Old textured paint or multiple paint layers – Over time, repeated coats can build up texture and highlight imperfections.
Movement or minor cracking – If there are cracks or raised joints, these should be repaired before repainting.
A few questions will help narrow it down:
Is the ceiling plasterboard or solid plaster?
Are the bumps spread across the whole ceiling, or just in certain areas?
Is it simply rough-looking, or are there cracks or flaking paint as well?
Is the property older (which can raise the possibility of textured coatings such as Artex)?
If you're hoping for a perfectly smooth, modern finish and the ceiling is uneven throughout, the most effective solution is often to have it skimmed by a plasterer, then mist-coated and repainted once fully dry.
If you can upload a photo of the ceiling (taken in daylight and another with the light shining across it), I can usually tell whether it just needs better preparation and repainting or whether it really needs re-plastering.

Aaron · Answer

If the ceiling is a painted plaster finish you need to sand down the area or the whole ceiling to the required finishes then prep it all and repaint.

Simon · Answer

Sound like it might need another coat or maybe sanding or some repair work.its hard to tell without seeing it.

Graham · Answer

Without seeing the bumps its hard to say....it could be that the paint was contaminated and bits have been rolled onto surface, or the plaster underneath needed sanding after the mist coat, before applying top coats. Either way I'd sand smooth, potentially use a product like Gardz to seal surface and then top coat with a flat Matt.

Scott · Answer

Hi - this would suggest that the surface was either not prepped correctly or paint applied incorrectly.

Errol · Answer

Slightly difficult to say exactly without seeing it but sounds like initial prep previously before painting may have required more sanding and making sure that the area was free of all dust etc & if marks are showing, that could one or two things causing that but the most basic reason could be that the ceiling may have required a further coat of undercoat or a stain removing coat if that type.
