Questions & Answers

Can this caulk be used on top of painted interior baseboards or should baseboards have paint removed first?

Asked by: Loveanimals45
It works fine on top of already-painted trim boards, blends well and bonds to the painted surface.

Can be used in Aluminum gutters?
Asked by: Jenny
I wouldn't use it in gutters. It will quickly deteriorate. Use an appropriate glue/sealant made for gutters.

My handyman used this for my kitchen sink. I see it’s not approved for that use can it be removed and redone?

Asked by: KP
You can, and should remove it. Then use a silicone caulking rated for bath and kitchen use.

Dynaflex 230 10.1 oz. Black Premium Indoor/Outdoor Sealant (12-Pack) is rated 4.1 out of 5 by 333.
Rated 5 out of 5 by from The trick is to let it dry thoroughly I have tried scores of caulks over thirty years of home maintenance projects, I have settled on Dynaflex for most interior and exterior uses, with the exception of places I know are either going to stay really wet, or need to be painted quickly. DAP's Sidewinder works well for those caveats, but it's harder to clean up and it doesn't finger tool as well. I'm only writing this review because someone was asking me about caulks today, and I couldn't quite think of "Dynaflex" since I didn't have a tube of it handy---so I checked DAP's website for the name, then came across the review from the person who had trouble with paint adhesion. My guess is that the gaps were wide enough to need a little extra drying time. I wait until the whitish color goes away completely, then it's safe to paint. It's flexible, it's easy to work with, it doesn't reek, it's easy to clean up, and it's relatively inexpensive.

First let me qualify that I am not a professional caulker, however i have caulked numerous times over the years with various products. I am familiar with other products from DAP so I decided to give this caulk I try. It's cost was middle of the road versus other options available at the store so I thought I should work well. Most of the caulking I was doing was vertical in nature and I was caulking joints between aluminum and steel. Before I applied the caulk I noticed that the consistency seemed a little too "soft" sort of like the consistency of warm mayonnaise. As I applied it had a tendency to not hold its shape and at times began to sag. The bead i was trying to apply was 1/4" wide into relatively tight joints. I eventually had to use caulk spreading tools to try to properly fill the joints and clean up the look but boy was that a mess with the caulk oosing all over the place. Bottom line, I have used other products in similar applications and have much better results.

I ordered Dark Bronze for a reason, and I can tell you beyond the shadow of any doubt, this caulk is medium gray, it isn't even that dark and is useless as I bought it to use around dark bronze schluter strips. No can do! It may be good caulk if you don't care about color, but it is NOT dark bronze by any stretch of the imagination, in fact, it isn't bronze at all! Very disappointed.

I had to do some caulking around a new pre-hung door to a stone house, and I wanted to get it looking good, I usually take a fine bristle brush and smooth it as I go, with a fresh tube, it's the best it's ever turned out. Thanks HD!

I installed 230 caulkwhen installing vinyl window replacements and 20 %of the windows failed in heavy rain areas. Not impressed with the product. I'm looking further into how well the installer covered the area needed to seal the window. study is still inconclusive.

Rated 5 out of 5 by from Hands down, my choice for latex every time I’ve used this on many projects to fill gaps and cracks between trim, and it does t seamlessly. Its easy to work with and cleans up with a damp rag, and if you put too much on, just take the extra on your finger and run it somewhere else.

If you have a project that's indoors and you need to paint it super quick they also make a product that's specific for trim work and it dries in approx. 30 minutes.
