Questions & Answers

Is there any reason to not use on interior window/door/baseboard trim other than it's a bit more expensive than comparables? We're considering a grey trim color and, in order for potential efficiencies (laziness), was considering applying this to already painted trim instead of going back over. Thanks!
Asked by: sjrKU
No, my experience with this product was very good and much better than some other similar products that cost as much or a little less. I used it on my bathroom trim with great results.

I have a small leak under the threshold of my exterior door.

Asked by: Nick
Thank you for posting your inquiry. When sealing door thresholds, we generally recommend the use of non-water based sealants such as DAP Premium Polyurethane. At your convenience, please feel free contact DAP’s Technical Customer Service Department at 888-327-8477, so that we can obtain some additional information from you about your project and to offer a more detailed product recommendation.

Asked by: Paula
I’m no expert as I had a handyman do my job, but in my conversation with him, he told me just about any caulk would work.

Dynaflex Ultra 10.1 oz. Gray  Advanced Exterior Window, Door, and Siding Sealant is rated 4.3 out of 5 by 79.

I bought a tube of the gray, and a tube of the "dries clear" type. The gray was runny and liquid, like the chemical components were separating. The "dries clear" type cracked as it dried -- just two hours after application, quarter-inch cracks appeared, right in the middle of the line, about every 8 inches.

This product flowed out of the tube smoothly, worked really well and did not shrink during recent extreme weather changes, which is a huge bonus because that's why I ended up having to buy this product in the first place. I'm pleased with its performance and look forward to not having to re-do the sealed areas for several years;)

It had air pockets in the tube and as I was laying a nice bead it popped and splattered and broke the momentum of the bead and made an added mess to deal with. As pricey as it was I should have been better packaged.
