ExoAir 120 and ExoAir 220 can handle intermittent temperatures of up to 158 ˚F (70 °C). ExoAir 130 and ExoAir 230 can handle intermittent temperatures of up to 240 ˚F (115 °C).

Primer is not required prior to application of ExoAir 120 and ExoAir 220. ExoAir Primer is also generally not required when applying ExoAir 230 unless you are applying it onto metal or transitioning it onto the exposed face of ExoAir 110. ExoAir Primer is required prior to the application of ExoAir 110.

ExoAir 120: 60 wet mil to achieve 40 dry mil  (25 sq ft/gallon)      
ExoAir 220: 70 wet mil to achieve 40 dry mil (23 sq ft/gallon)
ExoAir 230: 70 wet mil to achieve 35 dry mil (23 sq ft/gallon)
Note: There are 1000 mil in 1” (25.4mm), so 40 dry mil = 0.04” (1mm).

Yes, all the ExoAir membranes have passed the ASTM tests for nail sealability. The typical nail sealability tests include a smooth roofing nail. Tremco has also tested for nail sealability with a variety of screws and other fasteners. Please refer to the technical bulletin for nail sealability.

Construction gaps in exterior substrates less than 1/16” (1.6 mm) do not require detailing prior to the application of ExoAir fluid-applied membranes. Construction gaps greater than 1/16” (1.6 mm) need to be filled with Dymonic 100, Tremflex® 834, or other approved product. Allow sufficient time for detail work to cure prior to application of ExoAir fluid-applied membranes.

During installation, a standard wet mil thickness gauge is used every 50 to 100 ft² to verify thickness. It can also be approximated by staging material. For example, ExoAir 120 is applied at 25 ft²/gallon and if a 5-gallon pail is being used, approximately 125 ft² could be installed with one pail of product.  By applying the contents of one pail of ExoAir 120 to 125 ft² of wall area, you attain an average of 60 wet mil thickness over that area.

Allow the ExoAir fluids to cure for a minimum of 2 to 4 days prior to performing adhesion testing. If during this cure period the fluids are exposed to temperatures below 40 ˚F (5 °C), you may have to wait longer in order to achieve a full through cure prior to perform adhesion testing.
