DAP Alex Painters 10.1 oz White Acrylic Latex Caulk Contractors pack

This caulking is excellent for people on a budget but performs like a much higher priced one from the big box home improvement stores, [I should know - purchased a fixer up home 4 years ago and have used more than 50 tubes thus far!]. It dries quickly, fills in cracks and gaps of all sizes, holds up through all types of weather, etc. It's definitely water proof and I have used it both interior and exterior, around windows, gutters, foundations, concrete, storage shed - and on all types of material, [wood, metal, etc].

I used this to caulk the corners in an in wall shelf. It dried well and seems to look sturdy and sealed. The caulk is paintable. I attached pictures of my shelf. I'm a stay at home mom who built this. So this is easy to work with as a first timer too.
