Many of the coatings supplied by Diamondback Linings are temperature activated Your specific coating may (or may not) be affected by ambient temperature. For most of our DIY applied coatings, you can anticipate a longer cure time in general. Some of these coatings are slow to cure at temperatures below 75. You may need to wait much longer between coats or before putting your vehicle into service. Our pure polyurea, cartridge applied coatings are not affected by temperature, and cure in under 2 minutes.
The same application rules apply for temperature activated coatings whether applied in hotter or cooler environments. The vertical surfaces should be “thumbprint tacky” where it is soft and tacky, but does not come off significantly on your finger when touched lightly. At lower temperatures, you may notice it takes more than the typical 2 – 4 hours between coats on the vertical surfaces. As always, horizontal surfaces can be applied as thick as you like in a single coat. Our DIY products actually cure faster the thicker they are applied.
Something of note is that a slow cure rate, with high humidity can sometimes create amine blush when product is cured. This is a slightly waxy and/or oily surface residue. This is not a problem, but you should remove it with denatured alcohol or mild detergent and water before the next coat to avoid any possible adhesion issue. This usually just shows up after the product cures, not while still tacky, so if applying additional coats then, it is not an issue.
