Sikaflex - Keep in a bucket of water?

[STATUE]

Just tried to use some Sikaflex 291 I opened last winter and sealed the end with clingfilm - but all gone hard.

What about keeping it in a bucket of water once opened ?

Comments and better ideas please.

Regards.

Errr...as it's moisture-curing, probably best not to put it in water! You might try popping it in the freezer.

+1 for freezer. Swmbos don't like it though.

I keep things like that in a very cold but not freezing area of the fridge.

Placate SWMBO by placing it in a ziplock bag.

She wouldn't fit in the freezer anyway.

Maybe not in her present configuration...................

I just lob it in the deep freeze. It does it no harm as it doesn't contain moisture and the curing reaction is completely stopped at deep freezer temperatures. Lasts for years.

I find that wrapping just the nozzle in say two layers of cooking foil and squeezing out some sealant into it is effective in keeping the nozzle content soft.Also that even if the top of the cartridge has gone solid you can always access the still soft material in the lower half by cutting into it with a stanley.Obviously not usable in a mastic gun but 'trowlable' for bedding purposes.

You might get featured in the Daily Mail if you followed that to its logical conclusion!

As more and more are doing, avoid Sikaflex in future. Use for preference a modern improved flexible sealant that doesn't go off in the tube, costs half as much as 291, and all of it usable...... CT1.

Or PU40 from Toolstation at half the price of CT1. According to folk more knowledgeable than me on here it is identical to 291.

The builders of my boat used Arbomast BR, a butyl sealant. It skins but never sets inside. I had to remove a portlight a while back which took all of 5 seconds once the fastenings were out. I scraped off the old sealant and reused it. It really does stay gloopy for years. Not suitable for all applications, but great for bedding stuff.

Isn't it interesteing that Sikaflex never told anyone that their sealants should be kept in freezers once opened?We had to come up with it ourselves.I would have expected that bit of advice to be in their instructions but no.

Aberdonian, are we, Mr McDoon...?


And thanks, 'Quiddle', that's even better!

Thanks to all for the tips, I love Sikaflex as a product but recently avoided it for a job where it would have been ideal, as I only needed a tiny amount; I have noted the other stuffs mentioned too.

The forums at their best !

You wouldn't want to know the list of things I have reused in my life to save a few groats.

I near wet myself with that one!
