About this product range
Discover the pinnacle of sealant technology with DYNAFLEX 230® Premium Elastomeric Sealant, an advanced latex formula engineered with silicone-like toughness for a long-lasting seal that flexes seamlessly with joint movements caused by temperature and humidity fluctuations.

Its 100% waterproof and weatherproof properties resist UV light and harsh environmental conditions, effectively preventing moisture infiltration and resisting mould and mildew growth.

Both current Canadian White/Colours and Clear DYNAFLEX 230 sheets were checked. Directions require application strictly above 4.4°C; their application-range tables list 4.4–37°C. Use above 4.4°C and no higher than 37°C, with no rain or freezing temperatures forecast within 24 hours. The sheets do not separately define air and surface limits. Joint surfaces must be clean, dry and sound. White/Colours normally needs 2–4 hours before painting, longer when cool or humid. Clear applies white and can take 7–14 days to turn clear; wait until clear before painting. Service-temperature and freeze/thaw test values are not application limits.
Check the air, the actual surface, overnight conditions and the full drying or curing period. The current product label takes precedence.
