Sikaflex 1a Kit - One Component, Flexible, Non Sag, Polyurethane Concrete and Masonry Sealant for Vertical and Horizontal Surfaces, Sikaflex 1a 10 oz (Limestone, Pack of 12)

If you are doing roof work or siding work. This will seal forever. Best stuff I’ve ever found.

Excellent product .

I’m giving a five star because the batch I received has a 8 month shelf life and the previous two batches also had a long shelf life, which seems to be rare when it comes to Sikaflex. Sikaflex 1a is the best stuff you can get. It works on everything.. Don’t use it on something you plan on taking apart later lol it’s permanent stuff. If you’ve never tried it, you must get some because every contractor and handyman should have this product in their arsenal. It works great on concrete, wood, roofs, and almost everything else.

It’s a great stuff, to seal all exterior work I’ll be buying them in the different colors depending on the application.

Amazing product. Timing worked out perfectly as we were having our house painted. Easy to use and and clean up.

Very Good Product definitely going to be my supplier for this product for sure

One tube arrived in the box with a broken seal and was already hardened. The rest of the tubes in the box worked great.

Work great
