Would RecommendExcellent product, goes on smooth and dries relatively quickly. Fully cured in 24 hours. Color however is a much lighter gray than anticipated. Other than that, excellent product and does what it says.

Use 2 layers of Saran Wrap to seal the cap well!

Good Texture, But Not Gray
Would Not RecommendThis would be a 5-star review if the color were actually gray, but it's not. "Tan" would be a lot closer; please see my photo contrasting this product with actual gray mortar. The texture does look like mortar and the product is no more difficult to apply than any other caulk. We'll see how it holds up over time.

Hardscape joints
Would RecommendUsed this to point hardscape joints in a couple of backyard projects. Dries to the appearance of mortar. We'll see how it holds up, but was easy to apply and looks good.
