Use to redo some areas in my house. Easy to use, sticks great, and looks wonderful! Hopeful it will last longer than the last brand I used.

Easy and effective. Neat application waterproof and convenient.

I live in a townhouse and I have pests. If I see a crack or a hole, I have to fill it until my brother can come and fix it correctly. This product was so easy to use and clean, and neat. I will definitely buy more. Great for amateurs, which I clearly am, Lol, and I imagine professionals.

Don’t buy

Not worth the trouble. Have to remove and redo all the caulking. It attracts dirt and looks like crap.
