|Using Paints and Epoxies
Presented by Gary Goyette

|"In most cases using epoxy for restoration is cheaper than reconstruction,"
explains Gary Goyette as he demonstrates the process. "Scrape away the rotten material and brush on the epoxy
reconsolidant. Then a paste which contains a filler of micro-balloons or sawdust can be applied to fill the void."
|These materials are called fixatropic because they don't sag when applied to a surface.
They are also called exothermic since they generate heat when curing, and thus do not shrink.
One of the companies Gary recommends for epoxy restoration products is:

"A good paint job should last 7 - 10 years," Gary tells our group.
"Preparation of the existing structure will often require lead abatement procedures."
He warns that using a heat gun can also release lead vapor, "Wear a good mask and keep a spray bottle of water
at hand to quickly cool surfaces that get too hot."
He counsels us to use a three-layer system, a coat of primer followed by two top coats.
||"Don't paint in the full sun because the paint will skin, and always back brush
all your applications even if you spray or roll on the paint - to insure better penetration."
Gary also tells us to watch the dew-point, "Start painting about an hour after
the dew-point is reached and quit an hour before it settles back in." The dew-point is the temperature at
which dew begins to form. It varies with the humidity and temperature of the atmosphere.
