Default Dock Sealing

I have just had a new dock installed and want to seal it properly. Can anyone give some good products to use. The dock is over salt water and is in Virginia.

Ready Seal or Wood Tux after you clean it to remove any mill glaze

Default Re: Dock Sealing

Sealing wood decks and docks is only good for the suppliers and manufacturers of sealant.... Any treatment is bad for the wood. Period...

As soon as a sealant wears and allows water into the wood, moisture is trapped in the wood, wood doesn't dry, it rots. End of story.

Afish..........is ON TARGET...........been in the wood biz for 40 years.........NEVER ...NEVER "SEAL" A TREATED PIECE OF
WOOD".......trap moisture in and and ROT is quick to arrive..........let it retain and lose moisture naturally.....IMO never
use 5/4 x 6" decking.......use at least 2"x6' or 2"x8" stock treated.............( I use Locust or White Oak...)

Just Power wash once a year and you are good to go....

If you seal on the top how does that trap moisture into the wood? As for "NEVER SEAL TREATED WOOD," where did you get your information? You better look at what the Nartional Forrest Service says about that. Also your choice of wood for outside use?

Where do I get that info? Well first would be years and years of experience. My architect, who is also an engineer told me this too(for whatever that's worth). At this moment, my home (in NJ) has mahogany decks all around, never treated andin their 14th year, not a bad piece anywhere. My neighbors decks are one year newer, when the house was refurbed my best bud owned it, he had to have that deep red stain/sealer, believed the guy at the paint store over this old dummy. Five years ago when he sold, he had to redo over half the boards. Just clean themold off lightlyonce a year and you're good to go.

Think about it, common sense tells you a sealer will seal in moisture as well as seal it out....From experience I know this is a debate thathas goneon for pages, so I give in now. Put whatever you want on your decks, Thompsons needs your business.

Heee Heee...National Forest Service ??? They don't know the Specific Gravity...Densiy...texture...etc of the
various species.......Heartwood...Sapwood....Yellow Pine (slash/lobbly etc).....I have manufactured...kilndried
...milled....air dried...etc various of domestic and imports.....all wood dries from center out...hence surface checks .......treated wood is not kiln dried...it is treated green under pressure....makes no diff. if you seal one
side or the other....moisture will get trappe and hence shorten the life of the wood....

Most decks on the east coast in my area are yellow pine....treated....I use heart
white oak...or locust oak........power wash only.......the oaks will last much longer....

Default Re: Dock Sealing

Ok, so we have a disagreement. Since I started this thread this is what I am planing to do. I have ordered Wood Tux and am going to apply it to the top side of my pier. I am hoping that the sealer will keep the poundin rain and UV rays from splitting the decking. For those that think sealer does more harm than good and, for obvious reasons, I am not sealing the underside of the pier. I am hoping the wood will breathe and dry from the bottom side. See we can all agree now. I get to waste $150.00, ruin the wood and allow the wood to breathe all at the same time. Perfect!

Default RE: Dock Sealing

The absolute, WORST thing you can do to a wood deck, is power wash it! Yes, it cleans it, but it also opens the grain, considerably. Treated or not. To properly "clean" a treateddeck, you only need to use a good quality A/B cleaner.Have a look at this link

http://www.morrisonconstruction.net/DecksPorches.php

to see what happens to a redwood deck after it has been power washed (the before picture). He damaged it so badly, by power washing it, we had to go to great lengths to fully restore the natural beauty of the heart redwood. In my experience with restoring decks, and it is EXTENSIVE, the best product for protecting the wood(notice I said protecting and not sealing)I have found in terms of longevity, is Messmers UV Plus.

Be pretty funny to watch someone try to seal the bottom too.... The wood will not breath from underneath either.... You scuff your wood-tux or whatever by walking on it, that allows water to soak in that spot, and it stays in there. Air is not going to find its way through the wood.... Use the $150 for a nice dock ladder instead.

It's similar to what one might use for cleaner teak. 2 parts. A & B. But not quite as harsh.

Afish, you crack me up sometimes! [img]../images/emoticons/biggrin.gif[/img][img]../images/emoticons/rolleyes.gif[/img]

afishanado, I would suggest you finjd out what Wood-Tux is before you make statements about its "scuffing."

You need to mark a few boards and leave them untreated. Take some pics now, after treatment and in a year and so on. Report back to us then. This will be a good experiment and should clear up any questions about the practice of sealing treated wood.

since when do you scuff a wood sealer? I sealed my deck with an oil based product about 16 months ago and have had to do nothing to it and the water beads off it like a ducks ass. By the way the deck is about 8 years old.

Scuff by walking on it, dragging a cooler or table across it, sliding chairs on it is what I meant by scuff

Default RE: Dock Sealing

I build docks and I usually reccomend that customers use a stain with at least some pigment in it. If you are just wanting to put clear sealer on it don't bother b/c it really does very little to help the wood. The pigment in the stain is what protects the wood from UV. Messmers, Wood RX, Cabot, and others all make products that will hold up for about 2 yrs or so in the Florida sun. As far as trapping moisture in the wood, I have found that the checking caused by the sun allows moisture into the core of the wood. The core has little or no treatment and this causes rot. I also think the grade of lumber you use has a huge influence on the longevity of your dock. I would only use #1 dense treated SYP not the #2 prime garbage that HD or Lowes sells. Also if you want it to last use 2x6 radius edge decking (or Ipe' or Avek if money is no object) not 5/4. The 5/4 gets cupped to easily and holds water which shortens the life of the deck. I do agree you should not treat the under side of the deck boards and you should allow for adequate ventilation (which probably isn't an issue for a dock unless it is built to low to the water. As far as cleaning the deck in order to stain it or restain it pressure washing is ok, but you should use a 45 degree tip and light pressure. Don't stay in one place long and don't get the tip to close to the wood. If you use any of the cleaners make sure you follow the directions as most of them are acid based and can do damage if not done properly. Good luck and post a picture when you're done! I love to see a nice dock!

I know Im late but:

There is a product made by Olympic called something like "Wood brightner and Restorer". It's an acid and is available at Home depot. Follow directions!

If you have new treated lumber down, let it age/dry out a few weeks, then use the above stuff. But then let the surface get real dry for a couple of days after that treatment.

Then go over with a Cabot stain or solid. (please don't use an Olympic finish!)

The wood will soak this stuff up and give you the very best of outdoor finishes.

You don't need to pressure wash new wood, but you will need a garden hose to completely flush off and netralize the "Wood Briightener".

I can almost guarantee the results!
