Do I really need to waterproof my redwood deck?

Question

My husband and I bought a house with a redwood back deck, and with winter approaching, we were going to waterproof it, as we'd heard that was what you're supposed to do...Then this weekend I read an article by a carpenter/contracter and he said that there's no real need to do it, in particular the flat surfaces of the deck. He said that the flat surfaces in particular will simply wear unevenly and spottily, and we'll have to do yearly reapplications. I don't care if it stays new-looking, I know it won't.

So, if you have a deck or install decks for a living, what's your opinion? Thank you!!

Answer 1

Redwood will not rot, so you don`t have to seal for that reason. However, if you live anywhere it freezes and thaws, you DO need to seal it. It will absorb water, and when those wet boards freeze, they will crack and split. If freezing is not a problem in your area, you don`t have to seal, as long as you don`t mind it weathering and turning grey.

I stained my deck for years. It is necessary to keep them from rotting. Stain will last about 2yrs and it comes in lots of colors. If you just want to protect the wood use 50/50 turpentine & linseed oil. It really penetrates the wood & lasts quite a while. However I got tired of treating my deck every 2 or 3 yrs. & painted it with a high grade exterior gloss paint. It really looks great & is easy to wash off. If you primer it first it will last 6 to 10 yrs. Redwood will defenatly rot if any water stands on it. I have replaced a lot of redwood decks that have rotted!

It depends on the region. Here in Idaho, the sun is pretty harsh. I have never seen a decking stain last beyond 3 years and most do not last much past 2. I've always preferred the Cabot's or Superdeck lines of decking stains, better oils and metallic pigments that do not fade. You can reapply without stripping off the old as long as the deck is clean and dry.

Redwood does not need waterproofong unless you are in a climate where snow is there and freezing is frequent in winter.
The best thing to do with rot resistant wood is to clean between the boards where they meet the joist every year.If you have dogs that shed then 3 times a year or that one time will be trouble.[husky owner here]
But if your boards are not gapped and you live where snow comes every winter then treat it,trust your gut,not the internet.

Answer 5

I don't install decks, but at one time, I had one. I have always been told you should apply a protectant coat on your deck to prevent rot. I also understand that yearly applications are needed.
I hope you get some more answers.

That is very interesting news to me and one I will remember.

Thanks for the opportunity to respond.
