Instructions / Assembly

The following conditions may cause high moisture content

in wood:

hLeaky gutters and down spouts

hLeaky pipes or condensation on cold water lines in attic

or hollow walls

hFaulty flashing around windows, doors and where porch

and dormer roofs meet sidings

hEnd-grain wood that is not sealed with paint at all joints

around windows, corners, and butt joints

hPorch columns that do not have good drainage and

ventilation where they rest on porch floors

hSiding or any other wood that is in contact with the

ground

hSiding and shingles without sufficient lap so that water

is forced up through cracks by wind pressure

hIce dams

hCondensation of vapor within hollow walls

EIFS (Exterior Insulation & Finish Systems)*

Moisture intrusion problems in EIFS (also known 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-2100 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.

hPress read button

! and read the moisture content on

the display.

*Refer to the wood scale #1 if the sheathing is plywood. If

gypsum sheathing is used, refer to the gypsum scale #3.
