Prep work is an important aspect of achieving the perfect UPVC spray painting finish.
Here’s what you need to know about it.
If the UPVC is cracked or chipped, it will need filling with a suitable resin that is weatherproof and long lasting. The resin can then be sanded down with a fine grit. When painted, the repair should be unnoticeable.
The UPVC surface needs to be completely clean. We will wash the UPVC with soap and water to remove dirt and grime build up. We then use mineral spirits or white spirit to wipe down. This cleans the surface completely. After cleaning, any imperfections in the UPVC will be visible, which can then be attended to (such as filling).
After a thorough clean and inspection, the UPVC units are masked off. The surrounding area, such as brickwork and glazing, will be masked off with outdoor masking tape as well as plastic or paper sheet. Masking is necessary to collect overspray and it ensures we achieve a fine line right up to the end of the units.
We do not use a plastic priming paint as the base layer for our paint. Instead, we use our normal paint. We can do this because the paint we use is solvent-based and acts as a primer itself, bonding perfectly with the UPVC. Some companies use a primer, but we have no need, and we’re so confident of that all work has a 10-year guarantee.
Although it isn’t preparation work it is finishing work. As a finishing touch on all windows, doors and built-in units, where required we replace old sealant with a new sealant which is a perfect colour match for the new UPVC colour. This will give your units the appearance of new built-in units. In other words, they won’t look painted.
