This is probably the last boat that I will have carpet on. Well, at least the last I will install myself.

The boat was out for about an hour on both Wednesday, and Thursday of last week, just for test runs, so the interior was dry, and had very little traffic. But, it spent last weekend on the lake. It was put in the water on Friday evening, and not pulled out until Sunday. It was used for pulling tubes, (scout get together on the lake, people bring boats, and we spend the weekend skiing, and tubing and such) so it had water dripped on it, and a bit more traffic, but nothing real extreme, and still probably considered light compared to many boats.

On Saturday, I didn't notice any problems with the carpet. But, on Sunday, dad had the boat out for 4 or so hours, pulling tubes, and when he came back in, the carpet was bubbly, and seemed to shift.

But, the only place it had a problem was on the lower deck. And, both sections of the lower deck had an issue. So, I pulled a piece up to investigate.

Here is what is odd. See how the deck looks brand new, but where it was attached to the hull, the glue is still present? When I pulled it up, it came effortlessly off the deck, but I had a real struggle when pulling off the side.

Here is the piece of carpet. The glue stuck to the carpet at the deck, but at the sides, you you can see where it pulled away backing, and tore up the carpet for me to pull it out.

My first thought was that the glue somehow didn't like the deck alloy, as it is a T6 treated 6061 alloy, and I am assuming the hull is a 5052 (most modern boats are anyway) alloy, but that idea is shot. The bow deck, stern deck, and all the hatch lids are made with the same 6061 stuff, and when I pulled up a piece of the bow deck, it acted just like the side of the hull. The only other issues with carpet, I can attribute to operator error when installing.

Does anyone have a clue what the heck happened with the carpet on the lower deck? As a matter of fact, that section of deck was actually made with 2 pieces of aluminum, both from different sheets facing different ways (print side down, and print side up). I am really lost here.
 
Did you degrease that decking well before you put the glue on?

Sometimes those sheets have different things on them from the process of forming and may also be treated to keep them from oxidizing during storage.
 
That was dads and my initial thought, especially seeing as 6061 is most likely to have a surface coating for appearance. But, that doesn't explain why it stuck so well to the rest of my decking and hatch lids.

Also, forgot to mention, it is Lowes premium indoor/outdoor carpeting, and Henry 663 carpet adhesive. Reading on the Henry site, the 263 adhesive probably would have been the better bet, as it is waterproof, as opposed to water resistant, but I don't think this was in service long enough to have that problem.
 
did you prep the metal first .looks like it didnt bond to the floor maybe oxidation from being used on mine i wired brushed everything wash it down with acetone and used liguid nails around the edges and seams
 
No I didn't. It seemed to have been roughened up a bit from oxidation, and having been moved around various scrapyards countless times. The oxidation had removed the aforementioned shiny coating often applied to aluminum, so I figured I wouldn't have a problem.
 
yeah i would say to wire brush it down wipe it down good and lay some more make sure it dries about 5to 6 days first so it will be water proof if you was closer i would do it for you
 
It is amazing how carpet absorbs and how long it holds water.

Just a wag on my part but thermal expansion coupled with water resistant glue?

While your deck lids would be at or above air temp, your decking was probably fluctuating between hot and lake temp.

Also, were your lids made from the same sheet of material that your decking was?

Yes. I am considering pulling all the carpet out, and starting over, for a number of reasons (this isn't the only one - moreso the final straw). Still in thought over that.
 
clean it up and have a sprayin bedlinner materian installed . use white like the salt water boats .
i use a dap contac adhesive on my boats . have don for several customers no complaint
 
Hmmm, can't figure out why it did what it did. I used the Lowe's marine carpet and Henry 663 glue, and used a rolling pin on the carpet to spread the glue out/relieve air bubbles, and have had no problems. I did wait about 4 full days for it to cure before taking the boat out. Did you posssibly apply to much glue to those areas and it hadn't cured completely? Just a thought

That section was on for over a week. I think the hatch lids were the only ones with some discrepancies, as I think they had 3 days of dry time before the test drive, but had the full 5 days before having wet people on them. But, of course, they stuck.
 
i still say it needs prep if you look at the pictures the glue is cured to the carpet but did not bond to the aluminum take a brass wire brush over it wipe it down and it will bond
