Ultimate Disappointment

Skinning after the first rain. And was so sticky as glue, had to wash my hands 15 minutes after that. Total waste of my time and money obviously

I used it to seal up some exterior trim and fill some small gaps from where it warped, it worked well so far. I will be using it to re seal space around windows too. A little pricey though, compared to regular caulking.

I recently purchased and used DAP Dynaflex Ultimate 10.1 oz. White Premium All Weather Exterior Window, Door, Siding & Trim Sealant on some very old interior wood window trim. The caulk went on fairly smoothly considering how irregular the trim is because of age. See photos - they are two different windows, but the gap in the one photo is typical of the one I already filled. The caulk filled the gap nicely, and the best part - it’s paintable! AI says it can be used indoors. Tube says low odor, mold resistant, and more. I would buy it again.

PAINTABLE Dyaflex Ultimate Caulking

The Dynaflex Ultimate caulking come out smoothly. Easy to clean after smoothing it with your fingertips. What was hard to see until you read the tube it does say its is paintable. Usually paintable is more pronounced in the list of bullets point. What another good thing is paintable in 30 minutes. As the tube says weather drying time varies. I just waited an hour to be sure it was dry. The tube also say you can apply on wet surface that a plus if you have a small leak. Overall a good product.

Not Paintable in One Hour

Not Paintable in One Hour My three-star rating is based on the DAP Dynaflex Ultimate Premium All Weather Exterior Sealant for Windows, Doors, Siding and Trim NOT being paintable in 48 hours let alone the one hour claimed. The other three-star ratings already up on the site were due to the misleading listing in the Seeds program. I will address that later. I used the tube I received on a front porch renovation project. I needed a waterproof seal since this porch is directly above the basement and has had water infiltration issues in the past. The product goes on smoothly and like most pro level clear sealants, it goes on white and turns clear as it cures. We waited 48 hours before painting the waterproof membrane. It appears the paint would not stick where the sealant was still white and curing. I recommend this product for sealing things you don’t plan to paint. When I only received one tube I contacted the Seeds program, and they received this response from the vendor: "Below is the description that appeared for the customer when they were selecting the item. It is clearly written that shopper will only receive one tube of the product regardless of what the title of the product says, the title comes over automatically how it is setup, & this item is the 12 pack, so we clarify it in the description. Customer will receive 1 item (1 Each) and not a full case pack of the product to sample and provide feedback…” The “1 item” that at least four of us expected was a 12-pack.

Thank you for posting your feedback on DAP DYNAFLEX ULTIMATE (Clear). As indicated on the product package label and supporting product literature (in BOLD text): “Sealant applies white and dries clear in 7-21 days depending on joint depth, temperature, humidity and substrate. Cooler temperatures and higher humidity will slow down dry time.” All of DAP's (CLEAR) acrylic-latex (water-based) sealants will function this way and are labeled accordingly with similar information found above, regarding this color changing performance characteristic. As is the case with all acrylic-latex (water-based) formulas, the sole drying mechanism is the evaporation of water. Application under marginal conditions/outside of usage guidance will result in slower performance development. Because you did not provide any information on the size of the joint, application surfaces, surface preparation, application technique or application conditions, it is difficult to provide a more detailed response in this format. At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information from you and arrange to obtain a sample of your remaining product for evaluation. With respect to your commentary regarding the “Seeds” program, samples provided under this program consist of single/individual units (not case quantity). DAP

Very good window/door sealant!

This tube was great quality. The seal on the back was intact, the tip was well marked for what size bead needed, it was easy to cut and puncture the front seal. The flow and viscosity of the sealant was very easy to control. It fit my standard caulking tool easily and was used to seal a storm door. I expect the sealant to hold up to the weather and elements of the northeast and many year of service! I’m impressed and this is probably my new go to for window/door sealants.

Some creamy caulk

I really like this caulk. I have been using DAP brand for years for caulking interior and exterior projects. I like thus caulk because it seems to hold up well. I haven’t noticed any shrinkage yet. Make sure to cut your tip right because this makes a huge difference. I will say a gentle squeeze of the gun is all it took. The caulk comes out very smooth. I would refer this product.

Another Excellent Product from DAP

This DAP DYNAFLEX ULTIMATE premium all weather sealant is very different than other caulking and sealants I have used. The first thing I noticed was the consistency. It is much more fluid but still stays where you put it. It guns very easily, in fact I forgot to pierce the seal inside the spout, began to trigger, and noticed sealant starting to ooze around the pump end cap. I have never seen that before. My first use was to seal some end grain cracks at the end of an old oak threshold. While the white color initially highlights the cracks (and shows you where it is) the color turns clear in a few days. It skins over in about 10 minutes, adheres to wet surfaces, is paintable in an hour and remains permanently flexible. Not the least expensive but definitely has useful applications.
