## Description

Sealing heating/cooling ducts can dramatically improve the efficiency of a heating distribution system. Unsealed ducts typically leak about 10 to 15 percent of the conditioned air flowing through the ducts. Leaky ducts can pull unwanted air into the conditioned parts of your house and create pressure differentials within the house, exacerbating air infiltration and exfltration problems. Mastic is a fibrous adhesive sealant used for the coating of thermal insulation on pipes and ducts, and for the sealing of un-insulated ducts. It may be applied out of a bucket with a putty knife. The buckets are resealable, with a vapor lock seal lid. Mastic is non-toxic, non-flammable, and dries to the touch in 30 minutes. Origin: United States

## Customer Reviews

### ⭐ received product hardened in container
*by C***I on May 15, 2015*

was doing a retrofit of my a_c system.didn't open kings for 4 or5 weeks after I received it .when I opened it was hard as a rock they will not accept returns.product must have been out of date. Don't buy

### ⭐⭐⭐⭐ For heating ducts
*by A***R on April 9, 2013*

I used this mastic on my heating ducts in the basement to seal the small holes and potential gaps. You can lose a lot of energy and money due to holes in your basement heating ducts. Horizontal ducts are especially prone to holes. I alternated between directly applying it with a paint brush and putting it on top of electrical duct tape (don't use regular duct tape - it won't stay on).It seems to work great. Of course this is my first time dealing with heating ducts, but from what I've read this is a good solution.

### ⭐⭐⭐⭐⭐ Better than expected
*by A***S on May 5, 2014*

Works great for covering small gaps and holes in your duct work. Pretty easy to spread with a 2 1/2 in paint brush. I let mine dry then covered it with some tin tape - belt and suspenders but it gives it a clean look.For some reason I could not find this particular type in the big-box stores. Not 100% sure why.Depending on your ductwork a gallon may be way more than you need. I have at least a 1/2 gallon left so I will be applying it to my in law's ducts.Big question: return on investment. Depending on the sites you read it goes from 0% chance to 3 years or longer depending on size of house etc. The "0%ers" say all your heat/cool dumps into your house anyway so you aren't loosing anything. My view is I want as much air sent to the locations it was intended to go. If you feel too hot or cold chances are you change the temp costing you more.
