Polyurethane Sealant Marine Grade 2-Pack of 10.1 Oz Grey | For Use Above and Below Waterline |100% Waterproof Shower Seal

KBRS Poly-Seal is a polyurethane sealant that is perfect for sealing seams in concrete board. It is not suitable for setting tile, resealing leaky shower stalls, or repairing cracked grout lines as a patch. The sealant requires a caulking gun to dispense, and the minimum cure time is 24 hours. The product is sold in a grey colour and is easy to mould with silicon. It is recommended to go over the top of it with either a ShowerSeal membrane or a locally purchased equivalent to RedGard. The KBRS Poly-Seal Sealant is great for sealing shower bases/surfaces as a water barrier. However, there were some issues with the product's packaging not fitting in a caulking gun, and some of the tubes were dried up and unusable. However, KBRS quickly replaced the faulty tubes. There were some complaints about the price, with one customer discovering that the product could be purchased for half the price under a different label. Overall, customers appreciated the product's effectiveness, fast cure time, and ease of use with silicon.

Pros

Great for sealing shower bases/surfaces as a water barrier
Fast cure time
Easy to mould with silicon

Cons

Requires a caulking gun to dispense
Only available in grey colour
