Problem Solver - Painting a composite door
Composite doors are finished in a Glass Reinforced Plastic (GRP) coating of a specified colour which is designed not to fade or wear for the life of the door. GRP isn't made to be painted, but when chosen the following steps can be taken.
Stage 1 - Preparation
Wash down the surface to remove any surface contamination with clean water and a mild detergent, then rinsed again with clean water.
Use a fungicidal solution to kill any mould, mildew or surface growth and rinse with clean water.
