Commercial flooring adhesives are designed to be used within specific time limits after they are spread. Open time generally refers to the period the adhesive must remain exposed before the flooring is placed. Working time refers to the usable period during which the flooring can be installed and adjusted. These times can change based on temperature, humidity, substrate porosity, trowel size, ventilation, and the amount of adhesive spread. Placing flooring too early may trap excess moisture or cause movement. Waiting too long may prevent adequate adhesive transfer and reduce bond strength. Installers should follow the adhesive manufacturer's instructions, use the required trowel, limit the size of each spread area, and periodically verify adhesive transfer. The flooring and adhesive must also be compatible with one another and with the conditions of the jobsite.
