DIY silicones contain compounds harmful to aquatic life. When using sealants around ponds, be cautious and do not allow water to contact uncured silicone.
Our PU sealant has excellent bond strength and being black, does not stain. You will need a standard sealant cartridge gun available at most DIY stores.
