I have a leak around the shower tray waste. Silicon sealant works for a while but eventually fails.** A: Yes you can,but if you want long time solution buy new waste pipe fitments and put some sealant round after.Hope it helps. **Q: Is it safe on bird bath? It wont posion birds?** A: This should be safe, but may not work. **Q: Can it be used on caravan skylights?** A: On caravans I have had in the past it has always been the acrylic non setting sealants that are used because of the propensity for movement. I expect this might do a temporary job in some areas but depends on whether you need a proper, longer lasting job doing. **Q: How long does the sealant take to dry** A: It dries very quickly but due to my garden water fountain having a small hairline crack I left overnight to dry before adding the water and I have not had any problems since.
