What is the best treating product for outside wood products such as decks and trellis' to preserve and protect against intense weather conditions, such as snow, sun, rain and wind?

There are a few products you can use but none are one shot applications and forget it. There are products such as water seals that usually have to be applied every year or so. Paint usually peels after a few years and those areas have to be sanded and repainted. Solid stains usually have the same results. The best option is semi solid stains. They last about 3 to 4 years and they have to be re stained. The other option is to replace the wood trellis with vinyl and the deck with composite material. Neither product will rot but still may have to be repainted after a few years.
Hi, My hubby has built decks for years. He highly recommends Behr brand carried by Home Depot. It is a oil based product so it soaks in the wood for great protection. We know of cases it has lasted 5-7 years without reapplying. Alot of the brands are a silicone base and only coats the top then peels off within a year or two. We pressured washed and sealed our church privacy fence with the Behr and it looks new. I would guess you know to pressure wash before you seal it...some people don't realize this. I hope this helps you.... God bless!
I highly recommend Australian Timber OIl. It is sold at better lumber and paint stores. I have used it instead of water seal and there is no dirt or green mold even after a full New England winter. Keeps the wood in fantastic condition. You reapply every two years, and only one super light coat, not two. Good luck!
Although this product doesn't qualify as "thrifty" it works very well and lasts a long long time. The brand name is Sikkens" and it is usually special order at a paint store. I think it was $47 for a gallon but its worth every penny.

You basically have 2 options, you can either apply a stain (& the more opaque it its the longer it will last ...up to 7 years, but usually only 3 or 4 years) OR you can go the "Water Seal" route... These DO have to be applied every year or 2, BUT they can be applied with a just a simple $12 garden sprayer... Which is SUPER easy! ...They are basically a type of oil product (for a water barrier) that penetrates the wood with a UV filter added to stop sun damage. And the nice thing about the "Water Sealing" products is you can buy "Green" water Seal Products that will not hurt the environment.
---> You'll have to decide, do you want to do a super easy spray-on "Water Seal" water barrier " once every year or two OR do you want to go with the hassle of doing an opaque stain that is much more of a hassle to apply, but it only needs to be done every 5 - 7 years. I'd stay away from paint, unless you want to get out the sander every 5 or 6 years to sand off the pealing paint!
* BUT once you go with a product, you usually have to stay with that same family of products... There's a lot of info on the internet. I especially like to read info on wood workers forums & DIY & HGTV's forums. That's were I learned that Olympic's Brand of stains & sealers & is far superior to the Thompsons brand. (as in Thompsons water seal) It seems there's a lot of people on the internet that aren't happy with that brand. Do your research, you'll be glad you did! ... I was! At first, I thought "A stain is a stain", then I found out that some products perform much better than others & the more opaque a stain is, the longer it will last. Thankfully, we have the internet these days!
I have used Thompson's Water Seal with excellent results. When I want to paint a deck I use only Floor and Porch Enamel Exterior.
Hope this helps
Back in 1948 I learned the protective benefits of linseed oil. It is photo-reactive so it will eventually turn whatever woodwork it is applied to exposed to the sun an attractive dark color. That takes years of treatments, however, so don't worry about your deck turning black immediately.
It is derived from plants grown in northern states such as MN, ND, etc., so is ecologically desirable.
Wood products subjected to proper linseed oil treatment will last forever. You can even make a perfect "non-skid" treatment on almost any surface, concrete included, with linseed oil and fine sand, available at any lumber outlet. Oil the surface and spread sand evenly. Gently brush off excess sand. The oil cures and fixes the sand granules permanently. Seal the sand with another coat of oil. Better than commercial sandpaper.
A cute system I once read: Apply the oil once a day for a week; then once a week for a month; then once a month for a year. Thence, every year. Good exercise.
