MasterSeal NP-1 (formerly Sonolastic NP-1) Polyurethane Sealant Caulking 10.1 oz. Tube - 12 Pack ( limestone/Grey)

The builder told me to get this for the patio.A big box store had this but it was way more in price.I googled the product and Amazon had the cheapest price. ALL were the exact product, just various prices.It seems to be working quite well, and after this freeze we are hopeful this will continue to be working.Great product and super great cost.

Excellent seller and item!
