Review: Amazingly sticky and water tight. - Used this stuff to attach a side flare to my camper conversion and seal around it which it has done a great job of. My only gripe with this product is how hard it is to squeeze out of the tube without the aid of a battery caulk gun. It was easy enough to tidy and neaten up once applied. Have bought it again to do some more bits on the van and no doubt I will buy again if necessary. Review: Good purchase - Item as described and well packaged, delivery as stated. I would buy from this seller again. ## Features - Contains isocyanates.

Any sealant will potentially go mouldy / discoloured, all applications will require general maintenance to remove soap, detritus etc **Q: Is it anymore challenging to use than sika ebt or normal silicone? should it be primed for a shower?** A: This product is easy to use and it is better to use a Sika Primer **Q: Is this any good for sticking treadmaster/rubber anti slip deck sheets on a boat?** A: Suitability will depend on the rubber unfortunately, would check with the sheet manufacture for the type of adhesive to be used. **Q: is this tape water and importantly heat resitant?** A: Hello, 292 is NOT drinking water safe and NOT heat resistant. Sorry. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazingly sticky and water tight. *by T***M on 5 October 2022* Used this stuff to attach a side flare to my camper conversion and seal around it which it has done a great job of.
