Have a good caulk gun.
Would RecommendThis was difficult to get out with my basic caulk gun. It is very thick consistency. The product is great once applied. Color was perfect.

Terrific All Around
Would RecommendUsed this on several brick projects and been very impressed. Goes in easily and with some light finger work or troweling it looks just like mortar. It has a great shelf life too, have kept a half used tube on the shelf for a few months and come back to it and it's worked well. Very impressed with this project.

Amazing product
Would RecommendThis product does exactly what the description says it will do. And it does it very well. It was super easy to apply (be sure to dip your finger in a mixture of water and dish soap to smooth) and easy to work with. It is very flexible but looks just the texture of mortar. For once, I found a product that really works! Highly recommend.
