Paint Doesn't Protect. Learn how to seal your door.
I recently purchased a custom wood screen door, so how do I protect it from the elements?
Using finishing techniques like a proper exterior wood stain, Marine Spar Varnish, a layer of primer, and quality paint ensures your door withstands the test of time. However, the lumber you choose is just as important as any sealant.
At screendoors.com, we pride ourselves on the quality of our handmade wood screen doors. However, to ensure your door withstands your climate, we need to seal the end grain to prevent moisture access to the lumber.
We offer an optional white latex primer that serves as both a protectant and a base coat for whatever paint color you may choose. If you opt to showcase the stunning wood grain of your sturdy door, you may choose to stain it instead!
Wood staining is a relatively straightforward process that allows you to show off the wood species of your door. Pick the one that you like and apply coats to your desired color and finish. To seal your stain, the only product we can wholly endorse is a marine spar varnish. We provide more detail in our Finishing Your Door section. Following these guidelines helps to keep out water and add protection from the harsh sun out for longer, allowing your door to shine through any weather! It is always a good idea to inspect your door when the weather changes to maintain your quality finish.

We're getting ahead of ourselves with our sealants, though. Picking the right wood is just as important as how you protect it.
Your environment and the location of your door should dictate what lumber you choose. For exposed locations, our Sapele Mahogany is a great option regardless of climate, combining strength and beauty that shines through any stain and works well if painted, too. If you experience harsh seasons, this will withstand them like none other.
Selecting the right wood, stain, and position for your custom screen door guarantees that it will impress both you and guests for years to come!
