Can I paint my composite door?
Yes, where the existing surface and coating are suitable for refinishing. The door must be correctly cleaned and prepared before applying the new coating.
Do I need primer on a composite door?
Not every composite door requires the same primer route. The requirement depends on the substrate, existing coating and condition of the surface.
Can I paint over the existing colour?
A sound existing coating can often be prepared for overcoating. It must be thoroughly cleaned, degreased and suitably abraded first.
How should I prepare a composite door?
Clean and degrease the complete surface, remove any loose or failing material and abrade the existing finish to create a suitable key before painting.
Can I spray the door while it is fitted?
Yes, provided you can safely access and prepare all surfaces and properly protect the surrounding area.
How many aerosols will I need for a composite door?
The number required depends on door size, profile, number of coats and application technique. Our How Much Paint Will I Need? calculator can help estimate the quantity.
Which finish should I choose?
Choose the finish that best suits the appearance you want. Matt, Satin and Gloss provide different levels of sheen, so consider the existing style of the door and the look you want to achieve.
