I stripped my deck, power washed, and used neutralizer. Then I sanded the deck with a square buff sander and the railings with an orbital using 60 and 80 grit. The deck is 17 years old and is made out of cedar and the railings PT. I let it stand for a couple of weeks. I was washing it down with a hose to get any dirt the had built up on it as I was planing to stain it this weekend with twp 1500. I noticed some spots on the deck and posts and rails where the water was beading up. Will this prevent the stain from absorbing or cause blotchy spots? What would cause this?
Do I need to clean it with something else before I stain or wait longer?
Thanks,
Jim

any thoughts on this?

Not sure what would cause this except some remnants of old stain or sealer. Other option is over sanding? It is possible that if you stain that the TWP does not absorb in those areas and you can have shiny spots as it dries on top of the wood.
I do not think you can do much now about it and your prep does seem thorough. We would stain it.

I apologize ahead of time for this thread hijack, but I wish to ask a question in a new thread, and I can't see anything that would allow me to do that. No buttons to push, no "Start a new thread", nothing. Is there a waiting period for new members?

Hi, I have the same question as Skip above. How do I start a new post? Thanks

I purchased a condo which has a seven year old deck which is made of pressure treated lumber, (looks like pine) and has a fair amount of green mildew on the floor area. It also appears to have a recently replaced top rail of non-pressure treated white pine which has not been treated, just new wood and it has turned gray. The deck is exposed to full sun in Northern Virginia. There is no cover over the deck. What is the best way to get rid of the gray on the new wood and the best way too "treat" it after getting rid of the gray?
Also, what should I do about the green mildew on the floor and the best way too "treat" it after getting rid of the mildew?
Thanks in advance for your advice.
