Factors That Affect How Long Flex Seal Lasts
When it comes to determining the longevity of Flex Seal, there are several factors that come into play. Proper application, temperature, moisture and humidity, surface texture and quality, and the thickness of the coating are all important factors that can affect how long Flex Seal lasts.
Proper Application
Proper application is crucial for the longevity of Flex Seal. When applying the product, it is essential to follow the instructions provided by the manufacturer. The surface being coated should be clean, dry, and free of any debris or contaminants. Additionally, the product should be applied in thin, even coats to ensure proper adhesion and coverage.
Temperature It’s Applied and Used In
The temperature at which Flex Seal is applied and used can also affect its longevity. The product should be applied at temperatures between 60°F and 90°F, and the surface being coated should be at a similar temperature. Extreme temperatures can cause the product to crack or peel, reducing its effectiveness.
Moisture and Humidity
Moisture and humidity can also impact how long Flex Seal lasts. If the surface being coated is damp or wet, the product may not adhere properly and can peel or crack over time. Additionally, high levels of humidity can cause the product to take longer to dry, which can also affect its durability and strength.
Surface Texture and Quality
The texture and quality of the surface being coated can also impact the longevity of Flex Seal. Rough or uneven surfaces may not allow for proper adhesion, which can cause the product to peel or crack over time. Additionally, surfaces that are porous or have a low-quality finish may not provide a strong enough bond for the product to last, or will require more coats to get the job done.
Thickness Of Coating
The thickness of the coating is another important factor to consider when determining how long Flex Seal will last. Applying the product in thin, even coats will ensure proper coverage and adhesion, which will increase its longevity. Conversely, applying the product too thickly can cause it to crack or peel over time.
Cleanliness of Surface It’s Applied To
Finally, the cleanliness of the surface being coated is essential for the longevity of Flex Seal. Any debris or contaminants on the surface can prevent proper adhesion. Tthoroughly clean and prepare the surface before applying Flex Seal to ensure maximum effectiveness.
