We also now include a special 2 foam roller handle with pad and mini-tray for easier application to vertical and larger surfaces. How long will it take me to do? It takes about 45 minutes to prep a standard tub, and maybe an hour to properly apply the first coat. Then 4-5 hours of drying time and then a second coat.
Typically, a hot tub or spa will heat the water somewhere between 3 and 6 degrees per hour. First, letâs examine the ambient temperatures. Basically, that is the temperature where your hot tub is located. The warmer it is outside, the less time it will take it to heat. For example, if it is 76 degrees outside and you want to heat your hot tub to 100 degrees, it will take your hot tub approximately 4 hours to reach its temperature. You can decrease that time if you keep your hot tub cover on while it heats.
