This weekend, I’m planning to build an exterior crawl space entry cover to replace one that is falling apart. I’m building this both to abut the masonry closely in order to keep the insects and rodents out, as well as be as water-tight and UV resistant as possible. I’m pretty new to this, and trying to learn a lot of DIY skills and woodworking. I’ve purchased the lumber I intend to use, have the tools, etc. but have some questions about how to treat it in order to get the most mileage out of it (I live in the Southwest and this cover will get a lot of fairly direct sun).
My father in law, who will be helping me with the basic assembly, recommended staining the wood and then painting over it. From what I’m seeing from stain manufacturers in doing some research, they don’t recommend painting over the stains. Is this the case, and if so, how can I treat the wood for both water and severer UV resistance that will make it last as long as possible? I read up about water repellent sealers that are paintable according to some DIY websites, but even the manufacturers of these products on the retail page Q and A sections say they shouldn’t be painted over.
Thanks so much for the help!
