Expert Verdict Reviewed by the SuperArbor Pro Desk

Water-based TPO adhesives are the go-to choice for occupied buildings and VOC-restricted jurisdictions, though drying time depends heavily on ambient temperature and humidity. Apply in full contact with the recommended roller or spray equipment and allow full dry before mating the surfaces. Store drums above freezing because water-based products can be damaged by frost.

Protect from freezing during storage and transport, and follow the safety data sheet for handling and cleanup procedures.
