    When you close the foundation vents we recommend using a new 8" x 16" concrete block. Use this product to seal the new block to the foundation so that water and bugs cannot get in the crawl space. This caulk is great for sealing any cracks in the foundation as well. This is a 10.1 oz tube.

    Best mortar caulk

    Very pleased with this product. The caulk has what seems like sand in it so it mimics the color and texture of my existing mortar perfectly. Sticks well to concrete, easy to finish with applicator tip or finger. Buy more than you think as you will find plenty of places to use it.
