Good sealant for boat floor


opsirc

Question

I am redoing the floor in my boat and would like to seal the plywood before I put it down. Any recommendation for a good sealant that will hold up?

thanks

If you're just putting the plywood down to be used as your floor and would like a little color and durability, use Herculiner. This is a do-it-yourself bed liner kit that works! I have done two truck beds with it, the frame of my tent trailer, boat trailer and some other things. It is non-slip and holds up to pretty much everything. It doesn't chip,peel or fade if put on correctly. You can find it at many stores like Menards,Walmart,Fleet Farm,etc. in the black color. I believe they also make it in gray and red, but you can only order that online at Herculiner.com. I recommended this idea to a buddy for the floor of his boat and he is very happy with the results.

Opsirc, I know it's me but I still don't understand it.

Do you want to seal the wood from water ? Like with a waterproofing sealant (Thompson, etc. )....

Is it an aluminum boat or fiberglass? What kind of plywood? And like Valv is asking, are trying to seal water out of the plywood or trying to prevent chemicals from the plywood leaching out and reacting with the hull?

I used "spar" varnish on mine and my bro's boats, coated the underside of the ply and edges. the carpet glue sealed the top, I also wraped the carpet around the edge and stapled it to the bottom side of the ply to keep that edge attached.

ps, the original plywood (1/2" 3-ply) on the floor in both boats, 82-83 lunds was not marine grade nor were they sealed on the underside, so they did last a long time with out.

I am using standard cdx 1/2" 4 ply, I want to seal it to keep any moisture from getting into it.

Thaaat's what I wante to know.

Best way to do it is to coat it with fiberglass resin only.

Go to Walmart get a gallon of fiberglass resin, mix it with hardener and cover the whole board or at least the bottom, sides and top edges, use a regular paint brush.

That's the best way to waterproof it.

      You still have your trailer and place up there? Maybe you should do some summer rentals of it to help pay the taxes and up keep on it? 👍

      The water is starting to slowly go down. From what I can tell it looks like it’s down about 5-6 inches. The wind was terrible over the weekend though. I’m sure many properties suffered damages with Sundays winds. Things are finally starting to head in the right direction but it’s going to take a very long time for things to get back to even somewhat normal.

      Stopped at VC last week as well.  Didn't have pizza, but the sandwiches and appetizers we had were good.  The service was very good.  However, that's the first and only time we had been there.

      Any other info about VC?   Got kid and and fam coming up.  Been a couple years but really liked it.   Reviews on line still good.   Did Mark just hit on a bad night or has it gone down?   Being on west not a place we go often.

      Going up to visit family at Mille lacs 4th of July weekend. Given the current fishing restrictions and the fact that I don’t have a boat, does anyone know any good shore/kayak fishing lakes in the Mille lacs area?

      Spent yesterday afternoon wading the upper croix. Water actually seemed a little low. There was lots of floating grass, so my traditional approach of using a fire tiger jointed rapala was unusable. Tried a whopper plopper for a bit, which avoided floating grass better, but I just didn’t have confidence in using it. So since it seemed like the crayfish outnumbered the rocks, I decided to use a weightless Texas rigged plastic craw. Caught 3 smallies, and a pike.

      Here's the actual water level as of Saturday, 6-25. It has dropped some but still is 4 feet above the rule curve. This is updated daily; it's just too early in the day for Sunday's data to be posted. You can check it yourself here: http://www.lwcb.ca/waterflowdata.html

      @chaffmj, never mind.  I decided to take a cruise on up there today.  Had a couple popple tops in the driveway but nothing I couldn’t clear.  Nice to see the area again.

      Ludlows and Muskego both hit hard.  The Dayton place had a lot of big trees down, not sure of structural damage.  Some say a tornado skipped thru that area.  Looking at the destruction, I could believe it.  I feel bad for those impacted by this storm.   Below are a few snap shots of common sights around the area a day or two after the storm.

      Mike, was there a lot of damage in the Ely area?
