screwfix caulking

[Conachair]

Screwfix don´t have the greatest selection of stainless fasteners, but what they do is nicely cheap, 100 A4 M6 nyloks for under a fiver today

So is there a tube of something on their shelves which I could use to caulk between 2 pieces of teak on the cockpit coaming? Miles from a chandlers here and why pay that much anyway.

Edit - Is caulk the right word? Not that it matters, need a bead to tidy the join up a bit.

If you have a B&Q somewhere near I have used a bit of their brown stuff to seal a gap on my boat above the waterline. Has been in place for a couple of years and still is watertight. I'd say go for it. See http://www.diy.com/nav/decor/tiles/...eather-Protect-Exterior-Sealant-Brown-9786737

Hope that helps.

polysulphide sealant from toolstation?

 

[vyv_cox]

Toolstation, and others but I don't think Screwfix is one of them, sell PU40. This is indistinguishable from Sikaflex 291 by any means I know. £3.92 per tube.

Just bought some based on previous comments - thanks Vyv.

Does anyone know if this is available in black ? Believe Sika 291 comes in black but that is expensive compared with PU40

I've used a white version of this I think:

If you are sealing trim try this from Wicks, It's Butyl based and I have used it on all the trim on Little Ship

Any of them as good as Sikaflex for fixing a replacement hatch?

I have now used two complete tubes of PU40, one in Milford haven in winter, one in Greece. As I said further up, I cannot tell it from Sikaflex.

Thanks for the reply. However, I have been told by Seateach that the stuff to use for fixing a hatch to the hull is 'Polysulphide sealant' rather than PU. Toolstation do one at under a fiver.
But in answer to the original OP, Screwfix do not do a Polysulphide.

Do be aware that those nylon inserts are instead of, rather than as well as thread - so the nuts aren't particularly strong.
I've recently lost faith in Screwfix products, having bought several boxes of welding rods, only to discover their very poor flux quality. 'Tis my own fault for buying cheap.

Buying anything other than brandname welding consumables is pointless; the stuff is so cheap on ebay you may not be making any saving anyway even before taking account of reduced functionality.

I'm not sure how Ebay got involved - I'd never buy welding rods off Ebay, due to insane carriage charges.

I'm talking about Screwfix and my trust in the products they sell. I had expected these rods to be of middling quality that's all, just not branded - in the same way as one might buy Tesco brown sauce instead of HP.

I needed some MIG wire anyway, and Screwfix were offering free carriage if you bought £30 quid's worth, or something like that, so I topped-up the order with rods.
I only expected such cheap rods to be good enough for welding angle-iron together, nothing more exciting than that.

But these rods are not just poor, they are absolutely dreadful - the flux doesn't cool into a glass which lifts-off, but stays a soapy tar-like substance. I can just about use them on flat position butt welds where the slag can be 'dressed-off', but inside corners/ root passes etc, anywhere where 'sticky slag' would be a No-No - forget it.

So I just thought I'd mention it, seeing as Screwfix was in the topic. Maybe save other people some grief.

Sure your looking at the same thing? Looks DIN to me, 4mm thread 6mm deep altogether.

Anyway, got some brown frame sealant today from homebase so will give that a go. Silicon which is usually pretty nasty but it´s only cosmetic so will try a bit in a corner somewhere first.

Ta all.

I involved it as a 'for example'; I paid £40 for 10kg of brandname 308 rods; over the counter I'd pay 4-5 times that. Admittedly it's a large quantity and I'll still be burning them in my dotage, but I considered it a bargain. As regards Screwfix, Lidl, Aldi or indeed any other source of low cost unbranded welding consumable, I've never heard or read anything good about them, only grief about (as in your case) awful flux quality and porous or brittle welds. Apologies for the digression.
