The weather conditions can play a big role in the success of your application. First, never let the product freeze. COOL! Should be applied in between 50-85 degrees. During the summertime, the first and second coat of COOL! May need to be split into two days to avoid temperatures becoming too hot. Apply first coat the in the late evening or early morning to avoid direct sunlight and high surface temperatures. Do not allow the sunlight to heat up the concrete too much before applying. It is ideal to apply the coating to concrete as the temperatures are dropping, rather than rising. Applying during temperatures too hot can result in hard-to-manage product, bubbling, and loss of bond. Rain should not be expected for more than 24 hours after application. Our sealer will “blush” if rain is had too soon.
