Which Sika?

[petem]

Which Sika should I use for bedding fittings and generally sealing things?

Thanks.

I think 291i for above w/l and 292(i) for thru hulls et al. Check their online literature.

291 (or 3M 4200) for general purposes including thru hulls imho. 292 and 5200 for cases where you want ultra strong bond that you won't want to break like hull to deck mouldings. The (i) rating for sika is neither here nor there.

I don't use Sika at all for that sort of job. CT1 is just fine.

If there's a chance you might want to get it apart again, you might want something non-seeting, in which case, Arbomast BR is brilliant.

Thanks all. I assume once opened it goes off in the nozzle so won't keep (unless you have spare nozzles)?

I reused a tube for sealing the cat flap.
Just use a coat-hanger wire to purge the plug of solidified sealant from the nozzle, and you're good to go again.
(Sika 291i is probably overkill for a cat flap, but it was in the right place at the right time )

On the other hand, said cat flap is on Hayling Island, so you might actually be using exactly the right product, after all...

Thanks. Incidentally, B&Q sell a pack of 3 nozzles for 93p.

Errk! If the only thing between us and a flood is the cat flap, we're in trouble

Remove and clean the nozzle, put a piece of a thin plastic (plastic bag, cling film) over the end of the tube, replace nozzle.

I start the clean up operation to re-trace my steps, and the cat appears to investigate.
Mrs FP arrives at the stage where I have just Sika'd the kitchen taps as well, and very helpfully asks why is it that the cat now smells of Acetone?

Brilliant - you just summed up what happens whenever I do similar jobs with sealants.

Brilliant David

Drew a good chuckle!

A small warning on Sika.
A couple of years ago, I showed in this thread how badly the recaulking of my deck, made by a professional yard with the 290i DC, deteriorated after just a couple of season.
The pic I posted back then is not visible anymore in that thread due to the Photobucket crooks, but here it is:

Anyway, just for the records, it was afterwards confirmed and recognized by Sika that the problem was somehow connected with the formulation change introduced with the "i" version of their stuff - to the point that they refunded my yard (not just the material) for another full recaulking job.

Now, I don't know if this trouble with "i" formulations, whatever it was, affected also other products.
And it might well have been fixed in the meantime, I suppose.
But as the old saying goes, once bitten, twice shy...

Another vote here for CT1 it is amazing and a range of colours

I haven't used CT1 but I must say it looks good from the tech specs.

I have used Sika 291 for all mastic sealing jobs since Boatlife Polysulphide stopped being made. Not threads, O rings or gaskets though - I use Loctite 577 for that task.

If you have an open cartridge seal the end with some polythene or cling film then put it in the freezer until next required - this stops it going off, even the bit in the nozzle, and it will last for ever, just have to keep SWMBO sweet. When you need to next use it it just needs a couple of hours to thaw out.

Useful tip Trevor, thanks.

Looks like 291i has replaced 291.
