Suitable for vertical and horizontal joints. Cures to a tough, durable, flexible consistency with exceptional cut-and tear-resistance.

Review: Awesome sealer for concrete and gap filler - 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
Review: Sika Works - 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.

## Features

- Easy Application: Requires only a standard sausage caulking gun for installation, eliminating the need for specialized tools.
- Flexible and Durable: Accommodates joint movement up to ±35%, ensuring long-lasting seals that withstand expansion and contraction
