Permeable Liquid Flashing & Air Barrier

Membrane 3015LF - Installation Best Practices

Surface Preparation

•

To obtain the best adhesion, 3M

™

Permeable Liquid Flashing Membrane 3015LF should be applied when temperatures range

from 25° to 100°F (-4° to 38°C).

•

Surfaces should be clean, free from dirt and debris and have not absorbed water.

•

Surfaces should be free of any damaged, unsupported areas, sharp protrusions or voids.

•

Concrete must be cured a minimum of 7 days before application.

•

Block or brick walls should have mortar joints stuck ush.

•

While it can be applied as low as 25°F (-4°C) surfaces must be clear of snow, ice or frost.

•

Must be lapped a minimum of 2" with air barrier.

Mixing

Thoroughly mix the entire container of liquid ashing with a slow-speed (200 to 400 rpm) mechanical mixer (drill with a mixing paddle)

for two minutes or stick stir until the liquid ash has a consistent white color.

Application

•

Fill gaps and cracks exceeding 1/8" width with 3M

™

Adhesive Sealant 740UV, and tool the surface ush and smooth. Fill gaps

exceeding 1/2" width with closed cell foam backer rod or a foam seal, then with 3M

™

Adhesive Sealant 740UV, and tool the surface

ush and smooth.

•

After mixing the 3M

™

Permeable Liquid Flashing & Air Barrier Membrane 3015LF, apply to a clean prepared surface using at least

a 3/8" (8.5 mm) nap roller with rounded edges or 2" (50 mm) or wider brush. 3M

™

Permeable Liquid Flashing Membrane 3015LF can

also be spray applied.

•

Apply a minimum of 50 mils (1.27 mm) of liquid ashing onto the horizontal pan or sill surface and a minimum of 10 mils (0.254 mm)

of liquid ashing onto the vertical and top surfaces. Test the thickness using a wet mil gauge. Make sure material contains no pinholes

and is void-free and undamaged. Alternative: Use a 3M Sheet Flashing Membrane on the sill and 3015LF for the Jambs and Header.

•

Apply pail cover when not in use to prevent the liquid ash from skinning over.

•

Extend surface preparation a minimum of 2" (50 mm) beyond the termination of the ashing.

Stucco Adhesion

Adhesion of stucco to 3M

™

Permeable Liquid Flashing & Air Barrier Membrane 3015LF has been tested in lab conditions using washed

Mason Sand broadcast until rejection. Pull adhesion of >30 lbs/square inch was achieved. Adhesion will vary with substrate condition

and type of sand. Adhesion testing must be done by installation contractor with actual lots of sand to ensure satisfactory results prior to

application.

Coverage

•

10 mil thickness equals 160 sq. feet/gallon

•

14 mil thickness equals 114 sq. feet/gallon

When referencing the AAMA 200-12 (windows) and/or 400-13 (doors) standards, the 3M solutions for these standards include:

•

™

Permeable Liquid Flashing & Air Barrier Membrane 3015LF, a STPE-based membrane, brush/roller-grade liquid ashing.

•

™

Adhesive Sealant 740UV, a STPE-based, gun-grade, non-sag waterproong sealant.

•

Together, these STPE-based materials allow for wet-on-wet applications, thus minimizing downtime.
