Help! My Teak Slats are Curling Up!

The swim platform of my Beneteau 311 has Teak slats set in elastomer. The Teak seems quite good, but the elastomer has given up in a few places and the slats are lifting.

I think the repair must be to lift all the slats, clean underneath, and re-bed the slats in new elastomer.

The elastomer is not your normal Silicone - it is rubbery, and must have considerable adhesive properties. It is grey in colour.

Does anyone know what this elastomer is?

Any comments on the repair path I'm considering?

Tks,
Bill

Re: Help! My Teak slats are curling up!

I would reglue with PL premium polyurethane construction adhesive.
It has a tan color and the glue will work on the teak. Teak may have an oil which you clean off with acetone before gluing.

Home Depot sells the LARGE cartridge 28 oz tube for about $7
http://www.homedepot.com/buy/paint/a...ive-54376.html

I have found it holds up underwater perfect.

Scrape off the old glue from both surfaces. Use clamps and wood blocks. You can use plastic cereal bags under the blocks as the glue wont stick to that.

The old grey adhesive might be sikaflex concrete grey made for cracks. It is a soft grey polyurethane runs like thick honey. It is ok, but susceptible to some solvents which the PL is not.

Sikaflex-228 will do the job, however do not know if the brand is known in the US.

Re: Help! My Teak slats are curling up!

I've used the construction adhesive before, and it sticks like mud to a blanket.

Cheap too.

I'll give it a try. Oils from the teak are long gone, I'm afaid. :-)

Thanks folks,
Bill

maybe not. I would still consider a wipe down with acetone then let it dry.
After you scrape off the old glue from the teak, you will likely expose some fresh teak wood.

For this I would think about an extra coarse light hand sand on the teak backside to give it more grip for the glue. You could buy a single sheet of floor sand paper 24 grit with peel and stick on backing and cut it and stick it to a board.

Re: Help! My Teak slats are curling up!

The more I look at the old teak, the more I think total replacement may be the best answer.

Anyone tried this stuff?

Re: Help! My Teak slats are curling up!

really how thin are your teak strips?
And if stained- blackened get some oxalic acid deck cleaner and that will brighten them up.
The PL you can mix sawdust in and sand it down with random orbit coarse grit and will take a stain and look fairly decent as a wood filler for gaps cracks holes etc.... The sawdust color will color the final result. When filling mahogany I found mahogany dust to be a good match, likely teak dust for teak. If you want a light look you will have to use fine pine dust.

If using as a filler, sawdust has enough moisture to fully cure PL in thick layers. You need to keep it pressed down to keep bubbles at a minimum as it cures and cereal bags are great as the PL wont stick to that. PL also moves with the wood so it is a flexible filler.

Re: Help! My Teak slats are curling up!

The slats are about 1/4" thick. Down on the sugar scoop is a pretty harsh environment - it gets all the sun in addition to the water. I've just done the teak in the cockpit with a good pressure washing an Cetol, and that looks great, but the swim platforn slats are significantly degraded. The Plasteak may offer a virtually maintenance free solution, which is appealing, but I'm not sure how good it is - for all I know, the UV will destroy it in a couple of years.

Re: Help! My Teak slats are curling up!

PL permium is the best. But wear gloves it will stain your skin, and if you dont get it off before it cures your hands will be black for a week,,,, and you might have to postpone doing surgeries during that time and your boss might get really upset with you....hypothetically speaking ....

Thanks for the tips.

How did you know surgery was my hobby?

You could consider having a Sunbrella cover made for the swim ladder.

Re: Help! My Teak slats are curling up!

I think PlasTeak might be a little slippery for a swim step, it's not bad, just not as good as real teak. I'd replace with new teak to match, or remove the teak and then glass it up, fair, and lay new nonskid and paint. You really want a good grip back there, and if you paint your maintenance will be reduced. However nonskid while providing the best footing, can be uncomfortable to sit on while swimming. That's why teak is the best but most expensive option, good footing, looks great, comfortable to climb onto in swim suit, etc. But painted nonskid can also look great and is much cheaper in the long run.

Re: Help! My Teak slats are curling up!

You are very right.

I'm in the hurricane zone, so the bimini comes off for the summer, when we are away up North, and this exposes the cockput teak too. A way to protect all this Teak from the UV is required, and I'll give this some thought.

Re: Help! My Teak slats are curling up!

A few buttons and a nice Sunbrella cover will do it. I have covers for all the teak on my boat, handrails, toerails, everything. They're expensive to have proffesionally made, but they do such a nice job, with perfect fits and bound edges, and nice SS snaps and leather chafe gaurds in all the right places. And if you have a lot of varnished teak, it's wise to protect the investment of time and labor in that. Even unvarnished teak can benefit from a cover in places, but you have to be careful about letting wet Sunbrella sit on bare teak, it will raise the grain severely and grow mold and mildew. Talk to a pro canvas maker and he/she will have solutions for you. In our area I'd recommend Barrett Enclosures for canvas, they are pricey and specialize in full enclosures, but they do the best work. I'm sure there are many equivalant companies in BC.
