The Red Devil 0645 Concrete Repair Patch is one of the most practical, no‑nonsense crack fillers you can keep on hand for fast structural touch‑ups. The pre‑mixed formula is the real advantage here—no measuring, no dust, no mixing ratios to get wrong. You squeeze it out, tool it into place, and it immediately behaves like a proper cementitious filler rather than a thin caulk. It adheres well to concrete, masonry, mortar, and even works for filling small holes in stucco, making it a versatile repair option for both interior and exterior surfaces. Once cured, it dries to a hard, sandable finish that blends cleanly with surrounding material. For hairline cracks, it flows smoothly enough to fill without shrinking; for wider gaps, it layers without slumping. The 5.5‑oz tube is ideal for targeted repairs like steps, patio cracks, foundation lines, garage floor blemishes, and small stucco imperfections where a full bag of patch mix would be overkill. Cleanup is simple with water while still wet, and the cured patch accepts paint without flashing or discoloration. If you need a reliable, ready‑to‑use filler that performs like a small‑scale concrete patch without the mess of mixing, this tube delivers consistent, repeatable results.

I ended up dumping all the tube cement into a container because it was hard to not have the tip drip out cement everytime i squeezed.
