Liquid Rubber Caulk - Hybrid Adhesive and Protective Sealant, White, 4 Pack

I had a leak on the roof connects to the chimney and this did a solid job for small cracks.

WOW. What an awesome product. I used this to fill some gaps in my epdm pond liner (put seam tape over it after it cured, then coated with primer/neopond). The job was intimidating until Liquid Rubber came to the rescue. This stuff is a great adhesive AND waterproof rubber filler. What was once an anxious mess of an issue is now a breeze because of the liquid rubber suite of products. This caulk holds its shape, it sets up SO fast, and you can paint it in 24 hours. I mean WOW. I never thought I could be so excited about a waterproofing product, but I love this and Liquid Rubber earned a customer for life.

Works as it should

Dries very strong but beware that you need alcohol to clean it. I was even able to belt sand parts that had settled so I could reseal.

This is a great caulk for filling gaps and sealing. Even after a couple of years of intense sunshine and everything else the weather has thrown at it it hasn't shrunk away or cracked even in areas where I used it to fill some pretty large gaps just as a temporary measure until I can make more proper and permanent repairs.

Works very well.

Was as described and so far it's doing what they said it would do

This Liquid Rubber Caulk is fantastic! It’s super easy to apply, and it forms a strong, flexible seal that lasts. I used it to seal some gaps around windows, and it worked perfectly. The caulk dries quickly and doesn’t crack or peel. It’s a great value for the price, and I’m very happy with the results. Highly recommend!
