IN GOOD COMPANY<br />
Vendor highlight:<br />
The concrete sill acts as a sponge drawing moisture to<br />
the underside of the wood window sill. When the sun<br />
heats up the top of the wood window sill, the moisture<br />
is drawn up through the wood by evaporation. As the<br />
water evaporates, it pushes all existing paint coatings<br />
off in the process. The application of primers or finish<br />
coats on top of the wood window sill will not alleviate<br />
this problem. (3) The lack of adequate drip caps around<br />
doors and windows causes water to penetrate a<br />
building. Horizontal surfaces only create ledges for<br />
water to stand. Over time this water will eventually<br />
penetrate these surfaces. Many times, the use of<br />
traditional J channel on horizontal surfaces only<br />
creates a trough in which water will sit. (4) Gutters and<br />
downspouts working improperly can cause major<br />
backflows of water into soffits and siding areas.<br />
Gutters and downspouts must be continuously cleaned<br />
to avoid clogging in the spring/summer and the<br />
forming of ice barriers in the winter.<br />
Gutters must be inspected for proper pitch. If the<br />
gutters do not pitch toward the nearest downspout,<br />
the water will simply not flow in the proper direction.<br />
The downspouts must also be inspected to ensure that<br />
their length is adequate to carry water away from the<br />
building.<br />
Another source of exterior moisture is inadequate<br />
caulk. With today’s building materials, i.e. cedar siding,<br />
caulks must have increased elasticity. Most substrates<br />
expand and contract with substantial weather<br />
changes. In some parts of the country, the weather<br />
only changes a few times a year.<br />
The moisture solution<br />
Several solutions to the above sources of<br />
moisture would include the following: (1) Priming<br />
of all six sides of replacement wood. (2) Avoid<br />
abutting wood surfaces to damp surfaces, i.e.<br />
support posts for balconies or concrete pads,<br />
without applying some type of concrete sealer to<br />
slow the flow of water or place a metal boot at<br />
the base of the post between the wood and<br />
concrete. (3) Install flashing above horizontal<br />
surfaces with proper angles to shed water rather<br />
than collect it. (4) Clean all gutters and<br />
downspouts twice a year and maintain proper<br />
pitches on the gutters and (5) Consult AAA<br />
Painting & Construction for the proper caulk for<br />
your building. The use of polyurethane based<br />
caulk is recommended for this market.<br />
