Smartseal Rayleigh Review by Katharine W, 2026-04-29T08:42:19
Concrete sealer. I was dubious about using this product as it seems so watery but, just one modest application to my ageing bird bath fixed all the leaks. I applied a second coat to be extra sure. It simply seeped into all the hairline cracks, some as wide as 3mm and, no more creeping leaks. Very satisfied, a product that actually does what it claims to do.
