A CHEMISTRY drop-out has used his rudimentary knowledge to design a revolutionary paint which changes colour on the wall.

Chris Bramley's invention could transform DIY nightmares, with bright blue paint in the pot turning gleaming white once it dries on the wall.

The paint has a chemical additive which changes the colour and allows you to see where the second coat has already been applied.

Chris, who dropped out of a chemistry course at Newcastle University more than 20 years ago, said: "The additive changes the colour so you can see where you've applied the second coat.

"As the paint dries, it slowly returns to its original white, leaving a surface with no gaps in duplicate layers.

"After having to apply three coats on numerous occasions when painting rooms in the house, this is a huge help. I could not believe nobody else had thought of it first.

"I scanned the Internet but I could not find a similar invention."

The 40-year-old, who lives in Gateshead, said: "I thought computing was the industry for the future, not chemistry, and I switched to computing at university.

"I work as a computer networker, but I retained enough chemistry knowledge to change the colour of paint."

Chris is hoping his invention will be picked up by a major manufacturer.

He said: "I have applied to have the Colour Changing Paint patented, and I am waiting for some more additives to be delivered from Japan, the one country where I can get the stuff I need."
