My 4 panelled front door suffers from extreme exposure to the weather. The previous door rotted through so I fitted a solid reclaimed door, but quickly the paint began to flake off. I don't think underlying paint had been prepared properly at some stage. I'm now burning it all off. My plan is to sand down to bare wood, and repaint. I thought it would be easy to choose what products to use, but not so. Ideally I need something where I can complete the painting part of the job in no more than two days. Ronseal 10 year weatherproof paint for example looks ideal but from the reviews dries much too fast and the finish is not great. Do we have any professionals out there who can tell me what they use?
