Perfect for concrete patching!!
I have concrete bird baths in my garden. One developed pit like holes and the water just drained out. This was easy to apply, dried fast and hard. No more leaks!! Very pleased, and so are the birds!!

Does what it says on tub
Very easy to use no mixing involved just use straight from the tub, so far so good did start raining 😮 so was worried would all wash away but still ok hopefully will go slightly darker in time but overall happy

Almost white. No good for grey slabs.
Easy to use but impossible to match paving slabs. I've filled the cracks in two grey slabs but I think the filler will be visible from the moon. I've decided not to care.

Easy, Clean, and Effective Concrete Crack Filler for Targeted Repairs
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.
