Yes, DYNAFLEX ULTRA™ is paintable after just one hour with both latex and oil-based paints. This improves productivity by saving time and letting the user finish the job sooner. At one hour, the sealant is firm and smooth, so there’s no brush drag or marks. DYNAFLEX ULTRA™ provides exceptional paint finish results without glossing (“shiners”) or dulling the paint finish.

DYNAFLEX ULTRA™ White and Colors are rain ready in just one hour without washing out or getting damaged with permanent rain marks, eliminating the worry of a ruined caulk job and having to reapply.

Also, DYNAFLEX ULTRA™ is water ready in just one hour for White/Colors and two hours for Clear. It won’t wash out, unlike other latex caulks which require at least a 24 hour waiting period before exposing to water.

New DYNAFLEX ULTRA™ represents innovative breakthrough latex technology, truly making it a “best-in-class” latex sealant.

DYNAFLEX ULTRA™ clear offers the same performance features as white and colors with a few exceptions. Clear is rain ready in two hours versus one hour for white and colors. This is still significantly shorter compared to other latex sealants which typically require at least 24 hours waiting before exposure to water. Clear meets ASTM C920, Class 25 and white and colors meet Class 35. Also, clear also applies white and dries clear in 7-14 days, depending on joint depth, temperature and humidity.

Algae growth is common on the exterior of homes that get a lot of shade or are battling humid and hot conditions. It often shows up on the east facing side of a home but can appear in other areas based on the amount of exposure to shade, heat or humidity. Algae is unsightly and can be time consuming to remove. DYNAFLEX ULTRA™ is the only sealant on the market today that offers a lifetime resistance guarantee against the growth of algae, mold and mildew so the sealant stays looking clean and new.

DYNAFLEX ULTRA™ is available in White, Clear, Beige, Clay, Iron Gray and Dark Bronze. These colors are the top selling siding and trim colors.
