ASSESSMENT AND PREPARATION

7.4.

Inspect wood elements for damage, decay, or rot using an awl or similar tool.

1.2.

Remove any deteriorated or decayed wood.

* Surfaces must be chemically neutral or alkaline. Old coats of latex or alkyd paints must be removed, since they inhibit penetration of the silicate binder into the substrate and vapor-permeability. Flaking or peeling paints must be removed completely.
