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.
