FrameWrap UK are industrial contractors specialising in spray painting and the vinyl and film wrapping of commercial properties using architectural vinyls. They have a history of working with large commercial ventures such as Aldi, Premier Inn, Crowne Plaza, Williams F1. FrameWrap are innovators in painting old window frames during residency as well as after dilapidation renewal.

Recently, they were contracted to revitalise an industrial office space in St Albans, just around the corner of Promain’s head office in Hitchin.

Contractor: FrameWrap UK
Location: 45 Grosvenor
St. Albans
Substrate: uPVC window frames
Coating Used: Selemix Direct PU Topcoat
Colour & Finish: RAL 7016 Anthracite Grey in 30% Gloss (Satin)

With previous experience applying industrial coatings commercially, FrameWrap were open to newer and simpler paint technologies. After contacting Mark in Promain’s technical team, Charlie at FrameWrap was looking to find a simpler to apply, more cost effective solution to spray paint window frames and flat panels than the company had previously used.

After a discussion with Mark, we found they had previously used Kolorbond’s K2 coating. However, Kolorbond K2 requires more preparation before application can commence. For application on to uPVC, Kolorbond K2 requires application of a solution to allow the pores of the plastic to open up. On larger projects this all adds up to expense in man hours, scaffolding and time the commercial property needs to  be available.

Promain’s Window Frame Paint Advice

Promain suggested the use of Selemix Direct PU Topcoat. Selemix Direct PU Topcoat benefits from not requiring a primer. This means that Charlie and the team could make the most of both theirs and their clients time in a more cost effective manner.

Before Painting

The Grosvenor building originally had brown and light grey accents. The client specified the modern shade of RAL 7016 Anthracite Grey for the new coating.

Selemix Direct can be mixed to any RAL or BS shade and is also available in a various gloss levels. 30% gloss (the equivalent to satin) was chosen due to it’s soft sheen aesthetic and ability to not retain as much dirt as matt coatings.


Before application of the coating, firstly clean the window casement with Centrecoat R09 Heavy Duty Surface Cleaner. This is to remove any surface contamination such as traffic film, dirt etc. Afterwards, abrade the surface thoroughly with a Scotchbrite pad or equivalent. Perform a further cleaning with the Centrecoat R09 to remove any dust.

The Problems With Painting Plastic Window Frames

Typically, uPVC is a difficult product to paint. This is because uPVC is plastic. It can take up to a year for weathering to completely remove the solvents used in the manufacturing process. Because of this, if you paint plastic before this process has completed, the paint will more than likely fail and be a costly, unattractive mistake. The solvents within the plastic will try to escape. Inevitably, the product will suffer from solvent entrapment. Bubbles appear and eventually they will burst. Then the paint will peel off in sheets…not an ideal situation!

It is important to bear this in mind when a potential client contacts you. Especially when it comes to industrial commercial properties, being liable to come back an rectify a poor job is expensive, shoddy and unprofessional.


Giving Your Business The Edge On Professional uPVC Window Frame Coatings

Residential customers are also looking for cheaper and more eco-friendly alternatives to replacing old window frames. At anywhere between £200 to £900 per window, replacements are simply not viable for some end users. As technology advances, coatings that were beyond the reach of the general public are now cost effective solutions. Now it is possible for anyone to upgrading the aesthetics of their property in a professional way.

In recent years, anthracite grey (RAL 7016) and black (RAL 9005) have become fashionable options for window frames and conservatory renewal. Adding kerb appeal, having the professionals in can really make your property stand out versus your neighbours.
