Customer Reviews

Dynaflex 230 10.1 oz. Clear Premium Indoor/Outdoor Sealant (12-Pack) is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Contractor who loves this stuff I am a contractor who does many crown molding installations and was using Alex caulk for a while. I've been experiencing a lot of shrinkage / cracks opening because of the severe temperature fluctuations as of late in the North East. I changed to Dynaflex 230 at the recommendation of the Home Depot Paint guru whom I use locally. Sure as rain this was the ticket. I haven't had a seam open or a corner shrink in over 3 months since I started using this product. It works great, is affordable and carried by my local Home Depot so I'm a happy contractor.

Rated 5 out of 5 by from Best Sealant Out There Even though this says it's the Dynaflex 230 - it's not just the 230 you can buy in the store. This caulking is only a special order item and performs like it. I have to keep the UPC each time I buy it to make sure I get the same stuff next time. This product actually has a 50 year warranty (versus 30 & 40 on the others). I have used this on many outdoor window and siding repairs and have yet to have any callbacks. It does what it claims and makes my customers happy so I'm glad to take the time and special order it.
