PART 3 - EXECUTION
3.1 — INSTALLATION:
A. Verify wet work such as plastering and concrete is complete and dry. Verify building is enclosed and under standard occupancy conditions (60 - 850F and not more than 70% relative humidity) prior to start of installation. Commencement of installation constitutes Installer’s acceptance of surfaces and conditions.
B. Install products in accordance with manufacturer’s written instructions and in proper relationship with adjacent construction, including the following:
1. For adhesive installation to substrate, provide temporary support to prevent panel slippage.
Note: Impaling clips are designed to help hold panels in place until adhesive dries.
C. Touch-up, repair or replace damaged units until satisfactory results are obtained.
