    Q:Is this meant for exterior stucco hairline crack repair?
    by|May 19, 2024
    1 Answer
    Answer This Question

    A:  Thank you for posting your inquiry. DAP DYNAFLEX 230 is not designed, tested, marketed, labeled, or recommended for use as a stucco crack repair filler. For that type of application, we would recommend DAP ELASTO PATCH Flexible Patching Compound. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.

        Q:Can this be used to caulk around exterior threshold and door that gets a lot of weather and sun exposure?
        by|Apr 22, 2024
        1 Answer
        Answer This Question

        A:  Thank you for posting your inquiry on DAP Dynaflex 230 Premium Elastomeric Sealant. DAP does not recommend the use of Dynaflex 230 on "traffic surfaces" (general flooring, sidewalks, thresholds, or patios). Traffic surface applications require the use of more specialized products, such as DAP Premium Polyurethane Adhesive Sealant. Should you have additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.

          This product comes out white, then dries clear, but it also shrinks as it dries. Ended up applying twice to compensate for the shrinking.

          Lots of boing
          Very good caulk! Easy to apply and because it has so much elasticity, it seals really reliably. I ahd previously used a stiffer caulk for a bathroom vanity and it cracked. This one doesn’t crack even if you budge and wiggle the vanity.

            I needed ext caulk for siding (almond color) that was installed 2015. I tried the Almond color of DAP. It was a perfect match.

            This stuff lasts both on the job and in the tube!
            I live in NE Florida. As I write this, it is Jan 2024. I bought my new to me house in 2006. During the first couple months of home ownership, I tried to right all the wrongs left for me by the previous owner. My home has wood flooring, and there were gaps or spaces that looked unsightly. I found this brown Dynaflex 230 premium, the color almost matched the floor, and it seemed a easy solution. I filled the gaps, and sealed the tube for storage. I always put 2 pieces electrical tape over the tip, then wrap the nozzle round and round for a air tight seal. I keep my unused caulks in my hot humid garage. Today I needed some caulk for a project, color didn't matter, so I thought I'd see what I might have. I pulled this tube from a high shelf and began to unseal it. The tip material was dried and wouldn't budge so I cut some off the nozzle. After some effort, the cured material started to move and very soon pliable caulk began to flow. Wow, I couldn't believe it! It applied like it was bought recently, not 18 years ago. I am sold!!

              I like using this for base and trim and windows. Easy to work with and gives a nice finish when done. Seams to last and stay flexible. It set ups rather well compared to other's I have used and can be painted in the same day when you time it right. Definitely a go to for a lot of my projects.

              Thank you for posting your feedback. We are sorry to see your low star review on DAP Dynaflex 230 Premium Elastomeric Sealant. Because you did not indicate a time component, the size of the joint, application surfaces or application conditions, it is difficult to provide a proper response. 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 about your project and provide you with the guidance you need to move forward.
                Poor Quality Control
                As a quality control professional, I'd be mortified to see this. I bought a tube of clear caulk and it was actually white, as shown in the attached photo. Of course, I will return but that doesn't do much for my wasted time.

                Thank you for posting your feedback on DAP Dynaflex 230 Premium Elastomeric Sealant.
                We're sorry to see your low star review on DAP DYNAFLEX 230 (Clear). As indicated on the product package label and supporting product literature: " DYNAFLEX 230 (Clear) applies white and dries clear in 7-14 days (depending on joint depth, temperature and humidity). DYNAFLEX 230 is an acrylic-latex (water-based) chemistry, accordingly, the sole drying mechanism is the evaporation of water. Dry time can be significantly impacted by cool or humid application conditions, moisture in the application surfaces or by thick (deep) applications of the sealant. Clear acrylic-latex sealants cannot turn clear until all of the water contained in them has evaporated. Because you did not provide any project details, such as: size of the joint, application surfaces, surface preparation, application technique, application conditions or the amount of time since the product was applied, it is difficult to provide a proper 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. DAP

                  Color Completely Inaccurate
                  I bought Almond DAP caulk to fill in around door frame molding after new vinyl plank flooring was installed. The color shown on the packaging matched really well. That color on the packaging is not remotely close to the reality of the product which is slightly warm and off-white.

                  Thank you for posting your feedback. We are sorry to see your low star review on DAP Dynaflex 230 Premium Elastomeric Sealant. DAP DYNAFLEX ULTRA (as is the case with virtually all acrylic-latex/water-based sealants) will dry to slightly darker shade than the sealant appears in its wet form, however, this color change is not dramatic. In applications where color accuracy/color match is critical, a small test application would be recommended prior to proceeding with a full-scale application. The final color development occurs as the product reaches its fully dried state; however, 24 hours of dry time (under normal interior conditions) is typically sufficient for purposes of a test application. In addition, because there is no industry color standard for "Almond", colors are best selected visually (rather than relying solely on the color name). If you are dissatisfied with your purchase, the product may be returned to the point of purchase or returned directly to DAP for a refund of your purchase price. Instructions for this process can be found on the product package. Should you have any additional questions or require further assistance, please free to contact DAP’s Technical Customer Service Department at 888-327-8477. DAP

                    Mold resistant caulk
                    Worked well, I painted over it and so far no mold.

                    Color doesn't even come close to the color on tube
                    The color when wet was perfect and I was very happy with how it went on. But once it dried I was very disappointed. It's much more yellow than almond as you can see in the photo. Now after spending a couple hours getting all the old nasty grungy caulk off and completely cleaned it looks like I haven't done anything. Complete waist of time and money.
