Installation
• PREPARATION:

	- A test application simulating the project environment should always be done prior to final usage of Stego Mastic.
	- All Surfaces should be dry and free of loose materials, oils and other contaminants. The surfaces should be cleaned in the same fashion as the test surface in order to ensure proper results.
	-  Store above 40°F

• PENETRATIONS: For small pipe and rebar penetrations in Stego Wrap Vapor Barrier cut Stego Wrap just big enough for the penetration. Liberally apply Stego Mastic around the penetration to keep the integrity of the membrane intact. Stego Mastic can be applied by brush, roller, or sprayer.
• NOTES:
  1) For larger penetrations or wide cut-outs of Stego Wrap, use Stego Wrap and Stego Red Polyethylene Tape to repair and seal.
  2) Solvent-based products should not be applied over this product.
• CLEANING: Clean all tools with kerosene and/or oil-based cleaners.
