10 Best Cement Based Concrete Crack Fillers 2026 in the United States

The DAP 18096 Gray Concrete & Mortar Filler comes in a pack of 16 tubes, making it a great choice if you have multiple cracks to fix or larger projects. It is designed to work on cracks and holes in concrete, mortar, and masonry, both indoors and outdoors. One of its strengths is the silicone additives that give it better adhesion and water resistance, resulting in a flexible and durable seal that can handle some movement without cracking again. This flexibility is important for concrete surfaces that expand or contract with weather changes.

The filler is latex-based, which makes it easy to apply with a caulking gun and allows for water cleanup, so you don’t need harsh chemicals afterward. It also dries to a gray color that blends well with typical concrete, though if you want a perfect color match, painting over it is possible once dry. It is best suited for small to medium cracks rather than very wide or deep gaps, where more heavy-duty repair materials might be necessary.

If you need a reliable, user-friendly filler for typical concrete cracks that resists water and stays flexible, this DAP product is a solid option.
