A friend sent me to this website and I was interested to read some of the causes and problems involving uVPC turning pink..........I live on a Taylor Wimpey estate now, of some 600 properties and am currently in dispute with them. A minority of properties, blocks of flats and terraced houses were fitted with grey painted uVPC whilst the vast majority have either steel or aluminium powder coated finishes . The uVPC was used on properties built jus before and after the crash (2007) and although they deny it I am certain it was as a cost cutting measure.
After five years some doors and window frames developed the "pink plague" a chalky secretion from the substrate which covered the paint but can be wiped away.........now after 9 years we have the colours of the rainbow, pink, grey, green, white etc.15 years ago a large supply of uVPC was dumped on the market the problem was that the chemical make-up was wrong (incorrect amounts of chemicals were used in the production process) which is where the problem lies.
I experienced this with white window and door frames and under warranty men were sent out with highly toxic chemicals to put matters right. To work they had to wear what at best can be described as space suits with breathing apparatus. I thought no more of this until I moved and my current problem.
I called in a paint specialist who confirmed to me that what I had done before had not worked and subsequently he was used nationally to supply specialist paint which would solve the problem for 10 possibly 15 years. He will only guarantee his product for 10 years.
Currently Taylor Wimpey are playing hardball and it looks as though we will have to take them to court and sue under the Supply of Goods and Services Act 1982. There are about 100 properties involved.
The only way to solve the problem is to replace the uVPC during the warranty period - Taylor Wimpeys supplier has gone bankrupt so in Law they are liable.
