The product says fast curing time, so what is that exactly? This is the only product which actually gives no indication of its normal curing time.

I have only used this product in warm weather for filling tears in the rubber strip down the side of my boat and for this application I leave it for 24 hours before applying any more if required. I found that to mould it to the shape of the rubber strip it is best to use a plastic spatula dipped in white spirit. Hope this helps.

It's clear - like glass once it's cured & you can actually see through it. It works well with a reasonably strong bond, but not sure if it would be ok for a fish tank for example.

I have a crack in my shower tray which is leaking. would this be suitable to seal crack?

Yes, the sikaflex is much better than a regular sealant. I have just used it to repair a crack in a ceramic pot and its working well. The only thing about it is it's VERY sticky stuff. I use it wearing latex gloves to smear the stuff on with my finger, as it's hard to push out of the gun, and once I came to use it again it had sealed the nozzle with a solid plug of the stuff even though I had pushed a screw down the nozzle! So be careful not to get it everywhere when using it, you can't get it off again as it's far superior to your regular caulk.

Is it ok to fill window sill masonry cracks living on the seafront on the bristol channel? i.e salt and very high winds

well i used it around the bath not sure, but go give it a go may work for a time, think you need 'putty'

The Best

Sikaflex is the best in the business. More expensive than competitors but worth it, I keep coming back to it again and again. Exterior work I completed 3 years ago is still sealed watertight. Highly recommended

Excellent

Sticks really well, totally water resistant. Used this to fit a roof vent in the caravan..sealed it nice and tight. No water ingress. Also sealed around the edge of the caravan where it folds. Also fixed a crack in caravan window. Brilliant stuff.
