The process of painting uPVC
When painting uPVC windows and doors, we take every care and attention to ensure the process is carried out in accordance with our paint manufacturers guidelines.
Your product is checked into our storage area.
Preparation for painting uPVC is carried out using our specialist cleaning solution and meticulously masked (where applicable).
Once in the spray booth, the colour is applied by our highly experienced technicians in a controlled environment.
We can coat single sides or complete profiles. We can mask off product as required for each project prior to painting uPVC products.
Once the paint has been allowed to dry on our purpose built drying racks, a protective film is applied (where applicable). We then carefully package your product ready for collection.
Our uPVC paint
Firstly it is important to understand how our product works. It is different to most 2K products that are normally baked on after application. Our product produces a chemical reaction with the substrate to which we apply it onto. Thus saving the time and cost of baking the coating on, making this product very quick and cost effective in use.
This means that if there are any contaminates left on the surface of the PVCu the chemical reaction will not take place and the coating will not adhere to the substrate. Providing that the PVCu is clean, the chemical reaction will take place and there will be no problem with the adhesion which is exceptionally good.
We remove the protective low tack tape only from the side that requires painting.
We always check the general condition of components. I.e. cracks, marks, surface contamination, dirt, grease, silicones and any other defects.
Masking is usually required when less than 2 faces need painting. This can be achieved using standard masking tape. Masking off open hollow channels in extrusions. If co-extruded glazing gasket is required to be masked, there are tapes other than standard masking tape that will adhere to these.
These products should be cleaned with a 100% cotton lint-free cloth soaked in the AVKOTE cleaners. It is particularly important to ensure that all surfaces to be coated are prepared correctly. This is because the coating adheres to the PVCu by way of a chemical reaction with the surface, so if there are any contaminates (such as soaps and waxes) left from the extrusion process, the coating will sit on top of them and the chemical reaction will not take place and the coating will not adhere. Providing the surface is cleaned properly, the coating will adhere every time and will never come off.
When all preparation stages have been completed, our spraying process commences in our spray booth. Using a quality HVLP spray gun. A three-quarter coat and full topcoat are only required for most colours allowing the first coat to flash off before applying the top coat. We allow the component to flash off for a period of about 2-3 minutes prior to applying a clear coat if required, or entering the curing stage.
Once the sprayed components have cured they can be packed. Protective low tack tape is applied to any raised or flat surface areas that have been sprayed. All goods and documentation are now ready for dispatch.
