DAP DYNAFLEX 230 is a premium waterproof sealant for windows, doors, siding, and trim. With silicone-like toughness, it withstands the elements while offering outstanding durability, adhesion, and flexibility. Easy to tool, paintable, and low odor, it handles joint movement without cracking or crumbling. Perfect for indoor/outdoor use, ensuring lasting protection and a flawless finish.
To get a professional-looking finish after the sealant has been applied, smooth the bead of sealant with a caulk finishing tool dipped in water. Do this before the sealant starts to skin over, about 2-5 minutes.
Apply painter’s masking tape to either side of the joint before applying the sealant. Remove the tape before the sealant skins over – about 2-5 minutes. To remove, lift the edge up at a 45° angle and pull away from you.
Remove any old caulk from the seam or joint by cutting or scraping it away. Then clean the area with soap and water to remove dirt, dust, grease or debris. Rinse thoroughly. Make sure the area to be sealed is clean and dry to ensure good adhesion.
Windows, doors and trim are among the top applications for sealant for both Pros and DIYers. Many times consumers choose acetoxy silicone technology for exterior applications on these projects, however DYNAFLEX 230® meets performance standards of acetoxy silicone with the added benefits of being paintable, low odor, easy to tool and easy to clean up with soap and water. It is engineered with increased elongation by 33% to deliver increased toughness for outstanding performance against the elements.
Based on laboratory testing, DYNAFLEX 230® delivers the performance characteristics of acetoxy silicone, but with all of the advantages of a latex sealant (paintable, low odor, easy to tool and easy to clean up with soap and water). Beyond meeting the ASTM C920 Class 25 test standard (demonstrating over 50% total joint movement in extreme temperatures), the DYNAFLEX 230® also meets the same stress/strain tests as acetoxy silicone.
The term “composite” is a term used to describe synthetic building materials (including polystyrene, MDF and others). The synthetic building materials market is a $3 billion industry and is growing quickly, especially with molding and trim. Usage of composite and PVC trimboard has become common, and few sealants are able to claim compatibility with this category of materials.
DYNAFLEX 230® comes in a wide variety of colors to match the most popular colors of exterior siding and trim. Colors include: white, clear, almond, gray, clay, cedar tan, brown, bronze and black.
