## Description

Bluestar Flexible Concrete Crack Filler (Light Gray)

Review: Recommended - Works really good. Blends in pretty well. Easy to sue. How much you need depends on the length and how deep. Get a 10 OZ tube and use a dispensing gun. Much more consistent with the bead than hand squeeze.
Review: Performs as advertised, easy to use. - I have used this product and its companion products before. This time I needed the light grey color to match a crack I wanted to fill on a concrete floor prior to installing flooring. Once again it was very easy to apply in the smaller areas, and once a base fill was used, it worked equally well on the wider and deeper cracks. It dries quickly and stays just flexible enough to allow for expansion and contraction. I have now used it for both interior or exterior cracks and highly recommend it.

### ⭐⭐⭐⭐ Premade solution is easy to use and does the job
*by M***C on July 1, 2018*

Nice product, did the job filling hairline cracks in my patio concrete. Dried to a shade that closely matches the existing concrete. I used a craft brush to paint the mix into the lines and then wiped with a towel. Came out great.
