Composite doors are made from glass-reinforced plastic (GRP) which takes very well to paint. When the correct paint is used, the finish will last for many years and will be durable enough to cope with heavy use.
The right paint for a composite door is solvent-based paint. This paint forms a durable paint film over the surface of the GRP.
Now you may be wondering what a solvent-based paint is, bearing in mind all paints have solvents in them. The answer is quite simple: a solvent-based paint has high levels of organic compounds – higher than any other.
It is this high count of organic compounds which makes solvent paint stick to GRP better than any other paint. The solvents in the paint facilitate good application and bonding, to ensure a long-lasting, smooth finish.
Paint application technique
GRP is a smooth, perfect surface and therefore any imperfections in the paint application will show through in the finished project.
This eliminates roller, sponge and brush application – unless you want air bubbles and brush marks all over your composite door.
The most reliable technique for painting a composite door is in fact spray painting, which should be performed with a spray-painting gun.
Most people don’t have a spray-painting gun or the skill to use one, which is why there are professionals out there who can do the job for you.
We’re one such company. We specialise in spraying plastics like UPVC and composites like glass-reinforced plastic. The equipment we use is specialised and we custom order our paint to ensure it is engineered for GRP.
The paint we use is such a high quality we can use it as the base layer, or primer. The paint itself is sprayed in at least three coats, evenly, to cover the door. We spray both outside and inside to give your door that built-in look.
Plus, all our paint work comes with a 10-year guarantee.
