Dries Darker than Wet
4 out of 5 stars
Dries Darker than Wet
At first, it’s shocking to see it wet bc it looks like a chalky pink. After drying it darkens to a milk chocolate. Depending on how light strikes it varies the color depth. It went on smoothly. I moistened my finger to smooth easily which dried nicely next day. This is in my sunroom which’ll house my plants in winter as well as hibernate a few fishes. Can’t wait to receive the last bottle to complete. It had no fumes or noticeable smell. I had a fan going n my windows open bc it’s bn hot n humid. The batch of caulk that I received was fresh n easy to use. Not hardened at all. Very consistent in texture.

It has good performance and is durable so far! I don’t like how the color appears different!

    5.0 out of 5 stars Fills BIG 1/4" gaps in wood siding, no problem. Awesome stuff, easy application
    Reviewed in the United States on November 23, 2024
    Color: BrownSize: 10.1 ozVerified Purchase
    Using old-school white latex caulk on outdoor trim leaves a lot to be desired, namely it shrinks and splits where you need it to seal. Enter DAP Dynaflex. This fills BIG cracks, a bit over 1/4" just made it yawn and say, "can you please give me a challenge?" Flows and applies easily with a caulk gun, and if the label can be believed, stays pliant and won't fail. Time will tell, but so far so good.

    J’avais besoin de ce silicone pour refaire les joints à l’intérieur de ma douche. Après la première ou la deuxième douche la silicone a commencé à se détacher à plusieurs endroits. Je ne sais pas si c’est moi qui aie mal fait cela ou si c’était un problème avec le produit. De toute façon, l’effet de la couleur marron n’était pas aussi bon que je le pensais. J’ai du tout enlever. J’ai remis de la silicone blanche qui tient parfaitement. Je mets cette note de 3* car je ne sais pas si c’est de ma faute ou pas.

    Very liquid and runs. I’ve used this brand before from local hardware stores and never had this issue. Not sure if product was old but it should not run like this. Lost a lot of time and made a mess. I wish I had taken a photo. I had caulk all over as it was dripping and not adhering.
