No, you should not apply urethane over deck stain. You should sand down the old deck stain first before applying any other type of finish.

Can you use a roller to stain a deck?

Yes. The roller can leave stain and make it uneven or leave lines. You should back brush to even it out. Back brushing is going over an area with a brush while the stain is wet. This brushing will even out the color and remove heavy deposits if stain. Do only a few boards at a time. Don't apply too fast. Remember to immediately follow with a brush to even out the color and spread any heavy areas around.

Can you stain a vinyl deck?

Yes, you could stain vinyl, but I wouldn't. Actually, you could stain nearly anything it just wouldn't always come out the way you hoped. Vinyl would not take a semi-transparent stain the same way wood does. There are no pores or grain patterns to absorb the stain. The results would be a little odd looking. Every nick, scratch, blemish or other imperfection would stand out 100 fold. Your best bet, if you just want to change the color of your deck, would be to apply a solid, non transparent exterior stain or a quality exterior paint. The trick in doing either of those is in the prep. Because the vinyl will oxidize over time it must be removed or sealed out completely before applying a finish. If you take your finger and rub it on an area that gets a lot of sun, you will see the oxidization on your finger. First thing to do is power wash the deck. After it dries you apply a coat of exterior primer/sealer and let that dry. Then you can apply the color of paint you desire and you shouldn't have any problems. Remember, if you want your new deck color to last don't take short cuts in the preparation. Good luck!


How do you stain over water damaged wood?

Try using oxalic acid, also called wood bleach, on the water damaged area before attempting to stain the wood. If that removes the stain, sand the surface, use a wood conditioner or a clear stain as a first coat, then apply the colored stain. Once that's dry, apply a clear polyurethane for interior use, or a spar varnish for exterior use.
