Low viscosity sealant?

Recommended Posts

I'm normally a big fan of CT1 but does anybody have a suggestion for something of similar performance but a bit runnier? Something that will be easier to squeeze into a narrow gap. Has to be weatherproof/waterproof and preferably remain flexible. Primarily needed as a sealant rather than an adhesive.

Stixall

 

The clear stuff is good but avoid the white version I have not had much luck with that.

+1 for Stixall Clear.  I've used quite a lot over the last 12 months for adhesive/sealant jobs and it seems to do as it claims.  Good price from toolstation last time I bought some.

I used  clear stixall for the joins in my artificial grass and it's kept them in place for over a year now. It's very good stuff .

Sikaflex EBT + worked for me in an external application where several others had failed

I've always been very happy with the results of using Soudal Fix All Crystal.

Thanks all. I've delved into the datasheets for each of the suggestions, none of them list viscosity but some do have minimum joint sizes. So I think I'll rule out the Sika EBT, which states 10mm minimum. The others are all 5mm. CT1 don't give a figure, annoyingly.

I imagine the pre-cure viscosity will be more a function of temperature whatever you use so make sure it's warm!

 

(Somehow I always end up having to jobs that require nice runny product in the middle of winter so have spent many a day outside with pots of paint, sealant tubes, rolls of tape etc stuffed up my jumper to keep them working)

Sticks Like certainly seems more 'runny' than CT1 in my experience....

CT1 has its uses but it is very difficult to get an average finish and the clear and white look piss yellow after a while.

I've found the spray gets a good neat finish.

 

Always painted where visible so not noticed the yellow before.  Know of anything as good, but that stays nice and white?
