The exterior front door is weather damaged. I'm taking off the top layer of veneer/wood. What do I do next?
If it's a solid wooden door and you've sanded it, then you can paint or stain it. If you stain it, add a poly coating afterward for protection. If it's a veneer, you would have to replace that in order to stain.Paint would be your only option.
First you need to use sand paper removed old paint and smooth the surface. Second paint with all weather primmer before the final exterior paint you design. Hope this helped
