The most difficult problem in
maintaining exterior woodwork is designing a repair system for maximum
long-term performance in real-world environments. Solely addressing
the condition of the paint film rarely solves the real problem----
the underlying condition of the wood itself !
|
MOISTURE PENETRATION
The presence of a high moisture content in wood contributes to paint failure,
decay, and ultimately the expensive alternative of total replacement. Moisture usually finds its way into the wood via exposed end-grain, open
joints, checking, or imperfections in the wood's surface.
Rarely does wood decay from the inside-out.

 |
FRACTURING OF MATERIALS
Conventional epoxy repair materials fracture under the stress
of constant movement. Most epoxy repair compounds lack the flexural strength
required.
|
|
BONDING FAILURE
The forces of expansion and contraction cause inferior materials to peel
away from the wood. Conventional epoxy repair materials lack the high
peel strength necessary to resist expansion and contraction.
|
 |
|
 |
POOR SURFACE PREPARATION
Leaving the decayed and damaged wood behind greatly compromises the bonding
strength ot the epoxy repair material. Decayed wood, fungi spores, dirt,
air-born particles carried by rain, oils, and moisture all
inhibit proper bonding of repair materials to a sound surface.
|
Therefore it is
imperative that all contaminates be removed to a clean, sound
subsurface. Impregnating decayed wood fibers with epoxy provides
only a short term solution.

Not
All Epoxy Materials are the Same |
|
MARINE EPOXIES
Epoxy materials designed for marine applications gain their flexural
strength by the use of fiberglass cloth or the laminating of thin strips
of wood. The use of these materials are not practical in the repair
of wood in architectural applications.
BRITTLE REPAIR MATERIALS
Polyester repair compounds (auto-body fillers) and conventional epoxy
consolident materials filled with air, micro-balloons, and fillers greatly
reduce the flexibility and peel strength, only providing a short-term
solution.
