I have an old deck, about 12 years old now. It has never been sealed. I would like to seal and stain.?

Yes they do make a stain and sealer as a one coat application, it is available from Home Depot. I would suggest you not put a glossy coat on as it will become very slippery in moist or wet conditions. Once you slip on your butt you will soon regret applying a glossy finish. In order to get your color back you will need to remove the old finish as well as the deteriorated wood. This can be done by using a power washer and then a light sanding as the power washer tends to leave an uneven surface.

I just did this to mine. Basically the water-seal is mineral oil. Some are colored, but it isn't like a finish or something, it's an oil that sinks into the wood and helps to repel moisture. Keep in mind though, that the oil can cause your nails to loosen and/or slip if they aren't nailed down real well. So you may end up having to reapply some nails or screws depending on how old.

The oil will sink into the wood over a period of a couple days after you apply it. I don't recommend over application. A light spray on each board is good enough as the oil will spread and blend as the hours click by.

Pressure wash your deck, Unfortunately short of spar varnishing or actual

painting the gloss finish you desire will not materialize. The deck is

wood untreated and it will suck any finish up like a sponge thus leaving

a matte finish of sorts. If you decide to put spar varnish on the deck it will

bean every year ocurrance to keep up the appearance that you desire.

Go with either a transparent or semi-transparent deck finish they are

oil based and will last a few years if properly maintained.

You need to pressure wash it first and let it dry for several days.

They have tinted sealers by Thompson's Waterseal.

You can get this at home depot or lowes. I used a garden sprayer to spray my decks.

Use the modern acrylic waterborne deck stains. They fill cracks oil will not
