On non slip, houses and scrumpy.

[Guest]

I'm going to be putting treadmaster down on a steel boat, the deck has been painted with polyurethane, and as such I dont want to use the epoxy adhesive which is supplied by Treadmaster, as this is not compatible with the paint. I have spoken to Treadmaster who confirm that the epoxy adhesive would not be a great idea, and they havent a clue whether Sika would work.

As such I need to stick it down with something a wee bit more flexible, I intend to use Sikaflex 291 and was wondering whether anyone out there in the ether had ever used the same to stick this stuff down, or whether there were any other bright ideas.

By the way we're off sailing in June......anyone want to rent a house in Cornwall with huge shed, outbuilding with ISDN connection, 5 yards from a boatyard and 10 yards from the Tamar plus apple trees that make great scrumpy ?

Pleased to hear....

Don't want to rent the house, but where are you....if you've got a mooring at the bottom of the garden I'll rent that!

Stan, are you sure that Treadmaster's epoxy is not compatible with the polyurethane on your deck? I haven't got to the treadmaster stage yet but my steel boat is coated with Jotun epoxy and Jotun recommend putting the polyurethane top coat straight onto the epoxy - the epoxy IS the undercoat. I know you are proposing to do it the other way round, ie. epoxy onto polyurethane but it might just be worth trying a small bit somewhere where it won't show - perhaps inside a locker?

You're absolutely correct, you can put epoxy under PU but once the PU goes ontop, that it, you cant put Epoxy over PU. THe Polyurethane is a very flexible coat, the epoxy is a very brittle, though strong coat. Put epoxy on top of PU and it'll all start cracking and falling off after a time, as the PU "flexes" underneath.

I have the same on mine, I used five coats of Jotamastic 87 epoxy, (the grey stuff) before more coats than I care to remember of Polyurethane undercoat and top coat.

i have since found the Sika web site that has specific instructions for sticking non slip including treadmaster down using 291, you can apparantly use 292 as well though this is rather more structural adhesive. Plus I can get the 291 at a reasonable price (£3.89 a tube) which will work out cheaper than the treadmaster adhesive. (I've also found Treadmaster at £25 a sheet plus VAT, instead of rip off chandlers at £41 at sheet) Let me know if youve found it cheaper or if you want to know where I get it ?

Stan, thanks for the warning. I have been fitting out for the last 4 1/2 years but I haven't got to doing the decks yet. If I might give a warning myself re your cheap sikaflex...... I found a source of sikaflex at around that price, he is a regular trader at boat jumbles. I bought a box of 291 and when I got it home and read the small print, it was past it's "sell-by date", though only by a few months. This stuff is slightly thicker and goes off a bit quicker than the fresh stuff. It is still useable for some things but I don't think it would spread well enough for sticking down Treadmaster..... Do check the stuff you have found before you buy a large quantity of it!

In my work I use a range of goops including sikaflex on occasion and have noticed a wide range of viscosity in the same tube depending on the temperature. I would suggest leaving the tube out in the sun for a while (or artificially warming it if neccessary.) It may help you to make use of the cheaper stuff.

Oh - thanks for that, I'll give it a try......
