Purchased purple haze paint for the bedroom, quite pleased with the result at first then came the warm weather, my wife and son complained about a smell which they thought was cats(we have not got a cat) or possibly a gas leak. Following investigation it turned out to be the paint which gave off a foul odour when the bedroom wall got warm in the sunlight. Communicated with Wickes who said their supplier thought there was nothing with the paint, it was possibly a bacteria which was already present in the old paint, but we have never experienced this problem before.
