Plasterboard in New Build Houses: Can Paint Cause Smell?

Q.

Five months ago we had my daughter's room decorated with ordinary emulsion paint. Initially it smelt of paint, as you would expect. But after two or three weeks a bad smell developed in the room. It is a gaseous smell, not like paint at all. It seems to come from three of the walls that were painted white. The other wall that was paintd a different colour does not smell. Leaving the window open doesn't help. I have also tried leaving a bowl of vinegar in the room which seems to help temporarily.

I have contacted the decorator and he agrees with me that there is a smell but does not believe it is the paint itself. He says it is more likely to be something in the walls being drawn out by the paint. We live in a new build house where most of the walls are plasterboard. Is this common? Is it likely to be harmful to my 6-year old daughter and will it go away eventually?

A.

I would have to disagree with your decorator and say it is much more likely the white emulsion paint is to blame for the bad gas-like smell experienced in your daughter’s room.

What’s more it’s not a smell that will simply go away in time or be relieved by any of the familiar remedies, such as using vinegar or onions. I’m afraid that for the room to be made habitable again, the walls will need to be completely redecorated.

The problem could be either due to poor quality out-of-date paint – buying new doesn’t guarantee new paint - or, more likely, a bad batch of paint that reacts with underlying coat.

Re-Coat with Alkali Resisting Primer

One of the well known paint manufacturer has recently been bombarded with a number of consumer complaints that recount dilemmas very similar to yours. Common symptoms include the smell becoming worse when doors and windows are left open or when the room warms up in warmer weather. The smell has variously been described as sulphur and ammonia-like. If this matches your own experiences then you likely share the same trouble.

Ask Decorator to Rectify the Problem

If they are unwilling to concede the responsibility then you could try contacting the trade organisation Painters and Decorator Association to ask them for advice on how to proceed.

Complain to Paint Manufacturer

The company has reportedly not officially acknowledged the problem as being due to their paint, but have nevertheless offered unhappy customers vouchers for alkali-resisting primer and more emulsion paint. If the paint manufacturer is at least willing to offer this kind of compensation then you may be able to come to an arrangement with your decorator that won’t leave you out of pocket.
