EIFS (Exterior Insulation & Finish Systems)*
Moisture intrusion problems in EIFS (also know as
synthetic stucco) stem from leaking window frames,
improper use of or lack of sealant, and faulty installation
of flashing.
If you suspect a problem take a visual inspection. Look for
gaps around windows, doors, air conditioning units, light
fixtures, hose bibs, dryer vents and other areas of potential
penetration. Also look for visible signs of water damage. If
you feel a problem exists, use the
BD-10 with a #21-E
electrode. This electrode includes the #608 - (4”) insulated
pins.
Procedure:
hDrill two 1/4” holes about 3/4” apart at an upward
45˚ angle.
hPush the #21-E Electrode into the holes through the
polystyrene and into the substrate.
