How Do I Paint External Composite GRP Doors
Composite GRP (Glass Reinforced Plastic) doors essentially have a compressed plastic surface with either gloss or wood grain effect finish. The plastic is designed to provide a durable pre-coloured finish that is not usually designed to be painted. The colour pigment within the plastic is treated to be UV stable so that it lasts the life time for the door. However, with the right approach and preparation you can achieve a new look !
