Liquid weather barrier
Description:
Liquid Weather Resistive Barrier is an integral part of the most EIFS systems. This elastomeric, breathable coating has been engineered to span seams and cracks in approved substrates up to 1/16 of an inch.
Preparation:
The entire approved substrate must be clean and free of any contaminates. Surface and air temperature will be at a minimum of 45°F during and at least, 24 hours after the application.
Mixing:
In a clean container using a Goldblatt Jiffy Mixer (or equivalent) mix the weather barrier until a uniform consistency is attained.
Application:
- Liquid Weather Barrier may be applied by roller, spray or brush.
- When spraying, use airless equipment with a 0.35 minimum orifice and filter only at the inlet side.
- When wet, apply a maximum of 24 mils per coat, preferably 16 mils per application.
- Apply Liquid Weather Barrier at a rate of 50 square feet per gallon
