Final answer:
The ArmourStick HD base and cap sheet membranes need to be relaxed before installation to ensure proper adhesion and performance.
Step-by-step explanation:
The ArmourStick HD base and cap sheet membranes need to be relaxed before installation. The relaxation process is essential to ensure the proper adhesion and performance of the membranes. By allowing the membranes to relax, any tension or stress in the material is released, resulting in a smoother and more secure installation.
The relaxation process typically involves unrolling the membranes and allowing them to sit in the installation area for a specified period of time. This allows the membranes to adjust to the ambient temperature and humidity, which can affect their performance. The specific relaxation time may vary depending on the manufacturer's recommendations and the environmental conditions at the installation site.
