View Full Version : Thompson's Water Sealer for Dock

05-22-2010, 02:54 PM
Has anyone used Thompson's Water Sealer for their dock? I'd like to keep the natural color of the wood...so I am going with the clear. I've used Behr Natural 300 on our deck on the house and I think it is a bit darker than we'd like for the dock....are there any other options?

any feedback on this stuff, recomendations? The wood has been on for about 45 days...I think i am going to start next weekend so that will be just at 50 something days....here is a picture of the dock

Might suggest something with more penetrating and UV protection power...Flood, Cabot, and Sikkens make very good stuff. Actually nothing wrong with Behr products just think previously mentioned brands little higher-end/superior.

IMO, water sealers/deck stains one of those items you get what u pay for. TWS probably just not going to last that long and would require re-apply annually if not sooner. Dock/deck environment pretty harsh with sun, water, etc...higher-end oil based (linseed oil) products are going to last much much longer say 3-5 years. Rather be skiing & boating than dinking around with staining/sealing!!

Lastly, any product you use is going to darken wood slightly. Most brands going to offer a clear or transparent. Shoot by your local HD or Lowes ask them to let you test offerings/colors on a sample piece of wood. Might even offer sample/tester cans.

Good luck, hope you get the product and look you're after.

P.S. Nice dock!

Thanks for the reply... I've heard of Cabot's, but I didn't see it at HD today...is another big chain that carries it?

Penofin Or Sikkens Srd Is The Way To Go. Clean And Hit It Every Other Year. Do Not Use The Film Forming Finish Sikkens Unluss You Can Sea L All 6 Sides Of The Board. Ifits Aready Down The Answer To This Question Is No Anyway. Thompsons Is A Waste Of Time Being High Bead For About A Month Then The Sun Bakes It Away. Its Garbage...parrafin Wax And Paint Thinner.

In general the effectiveness of a clear sealer is determined by the amount of solids in the product. The downside to clear sealers is that they degrade with UV exposure. Thompsons has a great marketing campaign and brand awareness but in my experience is not a good product. Better choices out there. The Porter paint product (and similar from Pittsburg Paint) is excellent. Follow mfr's instructions and you will get results.

DON'T use Thompson or Behr, both are way over rated .... if anything look into this.

We use it all the time for sealing pavers, I imagine it'd hold up on wood as well.
There's a number you can call to find out, the company's out of Tampa.
