Varnishing a house deck? [deck refinishing] (2025 Update)

Jul 15, 2003 Last reply: 8 months ago 12 Replies

We have hired a company to refinish our deck. When they sent us a proposal, they specified two coats of their sealant. When workers came, they acted all surprised when I requested that they come again to put the second coat. I had to talk on the phone to the "manager" who tried to convince me that I do not need two coats, that it was a mistake etc. Their sealant, upon close examination, appears to be an oil based stain diluted with solvent such as mineral spirits. They said that second coat of that product will not penetrate and the deck will forever remain oily.



My general and limited woodworking experience suggests that for a 20 year old and dry weathered wood, it will absorb an additional coat. I requested that they leave a little bit of their sealant and tried applying it again today, and alas, it was absorbed by the wood after I wiped off the excess. I am sure that a second coat will make the treatment last longer.



So I do want a second coat. Any thoughts on my decision making process?



The color that they applied is called california cedar, but is more reminiscent of baby s*it. That's to say that it is brown and not very transparent. But it looks not so bad and it was our choice.



What I am thinking about however, is VARNISHING the deck on top of coating. Both the treatment and varnish would be oil based. I will thusly benefit from their sanding of the deck, and their treatment will allow me to use less varnish. I tried varnishing one rail with captain's spar urethane, and it looked frankly pretty good. Has anyone varnished a weathered deck? Is that a crazy idea? Maybe I should varnish rails only?



Thanks!

If they bid 2 coats this is what you should receive , I dought if it will remain sticky, it will dry as the first coat did. If they come back out be sure they are new unopened cans , so they dont just thin out your product. or deduct for the second coat, to hell with them.

the second coat will make it last more than twice as long, he bid it, of course it will help. He is a crook, the oldest trick in the book, you are not supposed to be looking , while he rips you off. If he gives you one bit of s*it dont pay , hire someone else for the second coat, pay him minus the second coat around christmas, he has lied to you twice already, on the bid and saying it will stay tacky, screw him, he is screwing you,,,, get it....

I did not read all your post,, dont varnish your deck or railing, when it fails you will have to strip it and sand , just stain it

What do the instruction on the can say, you have not said what product you are using, call the manufacturer. multiple coats of transparent stain will not peal or flake or scratch as someone has said

They say they make that stuff themselves. And what I think they do is, they take some oil, add some mineral spirits, add some stain, and mix it together. Of course that stuff will not flake or peel -- it is a liquid. But two coats may give me more protection.

They make it themselves, HAAAA HAAA HAAA seriously , they dont. ,they just buy it in a 5 or 50 gallon, I will bet this is their 3rd lie to you. put a little on your deck see if it dries..Good stuff has chemicals in it no painter can buy in small quantities,and todays modern chemicals and chemists do wonders no garage Idiot can match. With a warranty,and life expectation. In all my years painting I have never heard of that one. I would not use some s*it made in a garage, How are you going to get more to match the color... I think this guy is a rea scamo hacko and is playing you for a sucker, You dont believe me , call the paint stores in your area and talk to their managers abot this.

And what does the article say?

Don't use _anything_ on a deck that sits on the surface. You will have to scrape and sand later to refinish. It's just not work it. Perhaps some type of absorbing oil would be OK, but not a surface finish like a poly.

The same general advice should be used on houses, but since houses do not often have horizontal components, and since restaining has to be done more often than repainting, many folks paint their house. For some reason no one seems to mind redoing the deck more often, perhaps it's the relative size issue.

Are you saying that paint will last longer than stain? painting is usually re-done every 3-5 years I can't remember the last time I re-stained anything though!

M.C. somewhere in Ca.

Yes, I am. Paint is usually good for 5 years, vertical stain for about 3 years. Much less for horizontal. At least, that's what we typically see in the NorthEast.

If you lived around here, your deck would look bad in two years, your house in three.
