[VAC] Sealing plywood

["Weimers" <mweimer@xxxxxxxx>]

Years ago, I built a couple of boats using Clark Craft products. This
company is in Buffalo, NY.  They has good service at the time.  Anyway, I
remember reading about sealing plywood with epoxy. Anyone putting new wood
floors in their Airstream should consider this!

EPOXY-PLUS
A PERMANENT TOUGH NEW COATING FOR THE BOAT BUILDER

Easily applied by brush or roller. Fail safe mixing system 50/50. Adds
tremendous strength. No sanding required between coats. Sands easily for
final finish. Low maintenance surface. Remains extremely flexible when
cured. When cured, is not affected by gasoline, oil, salt water and highly
acid resistant.

Epoxy-Plus is a premium super tough epoxy coating primarily designed for use
on any surface where the ultimate in protection is desired. Whether you are
coating boatbuilding timber or plywood, two coats easily applied by roller
or brush permanently encapsulates the wood, rendering a strong resilient
structure.

Epoxy-Plus is applied in two separate coats. The first coat soaks deep into
the grain of the dry wood areas and saturates the fiberous cells. The second
coat is applied after the initial coat has hardened and creates a permanent
barrier against any type of vapor penetration.

The coated area will remain dimensionally stable and is permanently sealed
against water vapor which causes wood to rot. If additional strength or
abrasive resistance is required, we recommend our 7-1/2 oz. treated glass
cloth be used on the exterior surface.

Once the coated surfaces have completely cured, a fine finish can be applied
that will last for many years. Perhaps you have witnessed the rapid
degeneration of a painstakingly prepared surface into a series of checks,
blisters, and buckles once the surface has been exposed to the elements.
Epoxy-Plus can do what no other paint, primer, or wood preservative can do
and that is to permanently seal the structure to the harmful effects of
water vapor.

The key factor is that the wood must be sealed from both the inside and
outside and therefore is most effective when used in new construction.
Consequently, we feel that you cannot use a better preservative mate-rial
than Epoxy-Plus. Clark Craft has been in the boatbuilding business now for
over 50 years and all of our prototype designs are constructed using the new
wood epoxy saturation system which is simply the best epoxy coating money
can buy.

The strength of Epoxy - Plus is matched only by welding and is the wonder
fix - it for boat, home auto and industry. Due to its flexibility, it forms
a covering with unusual high-impact strength and long term durability. Epoxy
is non flammable and practically indestructible.


Penetrates and seals wood against moisture with a tough, flexible, permanent
coating.
Stronger and better than polyester resin for covering wood boats with
fiberglass cloth.
Repair dry rot damage and prevent further decay.
Ideal for stitch & glue construction.
