OVERVIEW
Installation of the WeatherWeld system is a simple S stepprocess:

1. Prepare surfaces, seam$, walls, nashings,drains, and penetrations.

2. Install base sheet

3. Sprayapply WeothetWeld reinforced membrane.

4. Spray al)fJy reflective acryliccoaling system.
s. Install flashings and roof accessories.

Contact WeotherWeld representativefor final inspection.

PREPARATION
PriOf to installation, ensure 1.h.;1t adhesion testingwasconducted in aocOfdance with WealherWeld adhesion testing PfOCe<ktro-s to verify a mirimum adhesion strength of four (4)poundS per linear inch(pli) to the applicable substrates. When calculating material requirements for a partiaJar projec:t, consideration mustbe given to applicator variance and S1Jface texture.

Confirm local wateJrun-orr ordinances andres-trietionspriOf to cleaning roof.

Pressure wash all surfaces receivir)g WeatherWeld to remove all dust. dirt. debfis and oUlef foreign contaminants.

If the roof surface becomes contaminated with dit1.. dust.or other particles at any time during the application of the WeatherWeld system,deaning measures mustbe taken to restore the surfoce to a s\i 1blecondition.
