SIKA Sikaflex 1a 20 oz Sausage, Aluminum Gray, 1 Unit, One Component, Elastomeric, Non Sag, Polyurethane Concrete and Masonry Joint Sealant for Vertical and Horizontal Joints

This product worked great as a gap sealer between the concrete slab and bottom plate of our wood framed workshop. It is very rubbery when cured so it won't crack or shrink, very similar to silicone but with a rubbery feel to it.I have also used it as a sealer between the window flange and framing of a window opening in new construction applications. I think you can seal gaps up to 3/4" but that's gonn use a lot of material for a gap that large. I reccomend using appropriate size backer rod, then top coat with this product.-MLC Remodeling

After cleaning the expansion joint between the garage slab and driveway, I followed directions to ensure uniform depth with foam. Application was easy and required some smoothing, it turned out great. I highly recommend this product.

Put in a channel drain and sealed to side walk with this product. Adheres nicely and easy to work with and dries fairly quickly. Good concrete joint sealer.

Flows and fills in better than most other sealants. Soft and flexible, tubes are large and cover bigger cracks/gaps.

As the other gentleman said it is only one tube. It is portrayed in front of a box to make you think you are getting multiple tubes for the price. You can get one tube on other supply sites for less than $8.

Great product ! But was sent the wrong color...

I used 4 of these to seal up an old trailer. It worked perfectly and was fully cured in about 5 days. Simply put an amazing product.

There only one sesuge in the box , the pictures showing more then one. And to expansive . Return will cost another $15 .
