## Overview

DAP Dynaflex 230 is a premium clear silicone sealant designed for indoor and outdoor use. This 12-pack of 10.1 oz tubes offers waterproof, flexible, and crack-resistant sealing for windows, doors, and trim. It fills gaps up to 2 inches wide, cures fully in 72 hours, and works effectively in temperatures as low as 40°F. Paintable and easy to clean with water, it’s the professional choice for durable, invisible seals.

## Description

Cured sealant is mold and mildew-resistant. For sealing around windows, doors, siding, trim, molding and baseboards. Exceeds federal specification TT-S-00230c, type II, class A and ASTM C920 specifications, Class 25.

Review: Best caulk for a lot of purposes - Dynaflex 230 is becoming an industry standard for outdoor caulk. It's a silicone/acrylic blend so it combines the best qualities of both. It's reasonably priced if you buy it by the case. And you can get it in a lot of colors. Because it's part silicone, it will stay flexible for many years and it's great for gaps that expand and contract with the weather. But because it's part acrylic, it is paintable which silicone is not. If you can't match a color, just buy the clear and paint it what you want. (The clear is also nice because it goes on white and turns clear as it dries, so it gives you an indication of when you can paint it) It's much easier to work with and less messy than silicone caulk. You should cut the smallest hole you can because it comes out very soft, softer than painter's caulk. The one downside -- and why I wouldn't use it indoors -- drying time is LONG -- I don't know what the guideline is, but I wouldn't paint it without giving it a full day in dry weather to set.
Review: Great Quality - I purchased a case for caulking around windows and doors. It applies easily and dries clear. It's very flexible when dry so it won't crack over time.

## Questions & Answers

A: Probably not. It is flexible but I don't think it will Last very long.

**Q: Does this clear dry more of the "milky/opaque" clear, vs the crystal clear/transparent?**
A: it dries clear cant hardly tell its on there but takes awhile to dry clear<
