Sikaflex-295 UV Resistant Marine Adhesive Sealant, 10.1 fl. oz Cartridge, Black (10.1 fl. oz Cartridge, Black, 1)

If you need it absolutely, positively, never to leak again, this is your product... just wear gloves.

Seals great but man it gets messy lol

Good stuff

came without dispenser spout

Good caulk. Stains white gel coat. Expect a good polishing will remove it. USE REAL MINERAL SPIRITS for clean-up solvent, not "mineral spirits substitute".

I have seen this stuff used on teak decks on boats. I wanted something original and functional for my ip'e deck stairs. All hard woods and composites can be slippery when wet. Traditional stair tread traction devices are bulky and in some cases can actually make you trip. Routered in the bottom side of my decking were grooves to keep the hard wood from twisting and warping. They also were perfect for filling with this caulking and adding a stylish note to safety. In practice this works and looks great. If it can survive the riggers of boating weather it certainly can last a long time on the backyard deck. Just mask off the grooves fill and let cure. Remove and install.

Worth to buy…very fast shipping,original products

Works
