Why Surface Temperature Matters More Than Air Temperature
A thermometer on the wall tells you about the room. The concrete is what the coating actually touches, and a floor sitting on cold ground lags the air by a good margin and stays there long after the heating goes on. We measure the floor itself, along with the humidity and the dew point, and the base coat goes down only when those three sit where the material needs them. If the surface is below the dew point there is moisture forming on it as you work, and nothing will bond to that.
Cold also stretches everything out. A resin that would be walkable overnight in July can want considerably longer in an unheated Prescott room in winter, and rushing the next layer onto one that has not properly hardened is how a floor ends up soft. The honest version is that your floor takes as long as the conditions say it takes, and it is worth the wait, because a floor that hardens properly is the one that lasts. We would rather tell you that at the quote than move a date on you twice. The conditions change the timings, not the layers: here is how a resin floor is put together.
