upvc frames turning pink
« on: September 02, 2008, 11:11:31 pm »
I have a few customers with upvc windows, where some of the frames seem to have turned pink.
It looks to me as though the windows have been made with a different batch of plastic, which over time has reacted to the sunlight differently.
Anyone else come across this, and have an explanation, cos' I would like to be able to explain what is going on.

Blessings

yes I have had a few like this - a good quality PVC cleaner will take the oxidised coating off restoring the pvc to white - there's a product, can't remember what it is called, that you apply after cleaning to protect the plastic.

Celulose thinners will fix it. Be careful with it and do a very small area at a time. Apply and then polish it off straight away.

Do you use a red scrubbing pad or a red bristled brush by any chance? The reason I as is that PVC discolouration is often due to the lead content of the plastic, which turns the frames grey,... but not pink!

Just remember that pvc frame parts turning pink is a sure sign that those sections are made from recycled pvc and there is no U pvc protection in those parts so they will break down quicker.
Ask any owner with pink sections and I would warrant their warranty is useless.

Better still don't ask.

Thanks guys.
 I knew someone out there would know something about it.

The odd thing is that, it isn't all of the frame, just some sections of a frame.

I use the sill brushes, which are red.

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.

An old lady on my round had this some 10 years or more ago, frames turning pink. She got on to the company who fitted them & to my surprise they replaced the lot under warranty. Not sure of the company though.

I came across this once.  The house was fitted with replacement windows.  They started turning pink.
PLEASE NOTE: This was before WFP, although it wasn't a customer's house anyway - it was her neighbour's place.
The person told me it was because they used recycled UPVC.
