I like deck stain to work with the floors inside ideally the same color but at least a color that is coordinating. IMO a deck should look like an extension of the interior . Waht was the reason for the indent on the left?

Is that decking pressure treated? Are you planning to use semi-transparent, or solid? You really should wait a good season or two if that or pressure treated to give the liquid a chance to come out of the wood.

Thanks we are working on a plan for a few months before staining with a transparent or semi transparent stain. The decking is pressure treated.

Go with Penofin stain/sealer (UV sealer is what you need).

I think the Natural or the Mission brown would be pretty w/the siding

They do have other wood stains. this is the Red Label before/after.

I've used the deck stain and have had to repaint it every year! used both the semi and the solid colors. they do NOT last. I would never recommend them. plus, it doesn't age well

I did the deck around my pond w/semi transparent in a blue shade. this was barely one year! looked horrible.

Thanks for the comment
