ACCLIMATION

Acclimate panels 24 hours in the room and 48 hours in more extreme conditions.

Floor joists and subfloors expand and contract with changes in humidity and temperature therefore MULTIPLY® underlayment and the subfloor assemblies must be adjusted to the surrounding room conditions that will exist during occupancy.

• Use caution when carrying and storing MULTIPLY® underlayment in extreme conditions.

• Separate and store panels vertically around the room or flat with a spacer between each panel to allow air passage on all sides.

• Avoid excessive use of patching compound and adhesive material and do NOT flood underlayment surface with a self leveling compound.

• Avoid storing near hot or cold spots such as windows, air registers and exterior doors.

Before installation, whether in new construction or an existing floor in a renovation, it is highly recommended the moisture content of the subfloor be measured using a moisture meter to determine site conditions are right for installation. Refer to the chart below:

CAUTION: A word about Seam “Telegraphing” Seam telegraphing problems are not the result of defective underlayment panels but can usually be traced to two main causes:

1. Improper installation including failure to sand all seams level or using excessive patching compound.

2. Changing site conditions including expansion from moisture entrapment or movement in the subfloor.
