The restoration process is simple and easy to do.
Painting contractors can do it quickly and easily. Homeowners
commonly do it themselves. The restoration process is illustrated here: Six Steps
to Restoration with Smith's Clear Penetrating Epoxy Sealer. The first three steps are explained below: Here's One Reason Why This Is The Only Technology That Works: Here's Proof: Here's Another Reason Why: Here's Proof: Here's How an architect can specify the products for
Restoration or for
Painting. Here's More Proof: Here's Another Reason Why: Wood naturally contains water, typically 8% to 15%, even 25% or more in humid environments such as around boats
or in chronically humid climates. The solvent system that carries the natural wood resins of Smith's Clear Penetrating Epoxy Sealer
into the wood has to be capable of dissolving that water, so that the penetration show in the prior examples can happen. Products
made using water-repellent petrochemicals such as benzyl alcohol cannot do this. None of Smith's products use benzyl alcohol. Here's Still Another Reason Why: How did Steve Smith come to invent this? Here's Steve Smith to tell you in his own words: Being a chemist and a physicist, I was able to approach the problem of wood rotting and paint failing
scientifically, which no one else in this or any related business ever did; there were and are many people making epoxy
products, but none of them had a comparable background and were able to approach the problem by identifying the root causes
of wood failure and product failure. Peeling paint and rotting wood on wood building exteriors has been common since buildings were first made of wood;
there never-before has been a truly effective solution. The conventional maintenance for peeling paint consisted of scrape, putty
and paint, and again in a few years scrape, putty and paint. No one realized that the wood fibers themselves were rotting in a thin
film under the paint (fungal spores are in the air, everywhere), and its bond to the wood then failed. This increased dramatically
in the fifties, when lead oxide (a white pigment) was removed from primers and paints due to growing concerns. There was no
substitute provided, and without this mild but effective preservative, even good-quality wood began to rot sooner. The faster-grown
wood used on residential and commercial building construction a few decades later had much of its natural rot-resistance bred out
of it by the lumber companies whose focus was entirely on making more lumber faster. Even the highest-quality paints were failing
sooner on wood with little rot-resistance. So, there was an abundance of failure and a complete vacuum of effective solutions. Because I am a scientist I
had the ability to observe and to understand what others could not. I was thus able to develop this modern and effective technology.
You can read more about the details of the development of my technology here. My first customers were people with rotting wood on their wood boats, in the early seventies. The Marine
environment is vastly more severe than the Architectural environment. After a decade of exceptional performance on boats, the products
spread quickly into the architectural marketplace where they easily outperformed the hundred-year-old wood-maintenance technology
and products that were all-there-were in the paint, hardware and building-supply stores. Everyone clearly understood that if it
worked on a boat, it would definitely give superior performance on a building. After forty years, word-of-mouth about Smith's Clear Penetrating Epoxy Sealer is on every construction-related
and boat-related forum where people tell others about the product. Even if they don't use the full name (I admit it is quite a
mouthful, but I believe in naming products for what they do) but only two or three of its words, it's Smith's Clear Penetrating
Epoxy Sealer that they are talking about. Look for my name on the container; that way you know it's genuine. ------Steve Smith Now, here's more information about the product, its performance in different temperatures, and the Cold Weather
Formula for use in colder weather, even down to freezing.
The long working time (pot life) of these products mean
they will retain their penetrating and moisture-dissolving ability for
more time. Working
in cooler weather? Use Smith's
Cold Weather Formula™ The Cold Weather Formula™ of Smith's Clear Penetrating
Epoxy Sealer was developed because sometimes repairs such as restoration
of deteriorated wood, repair of osmosis-damaged fiberglass boats, and/or
adhesion-promoting priming for sealants or coatings must be done in the
winter. The particular kind of resins that must be used in Smith's Clear Penetrating
Epoxy Sealer in order to obtain all its usual performance features, which
have made the product famous, do not cure well below about 50° F and
essentially stop curing by 40° F. This is a normal characteristic
of these products, and has been well known to chemists for half a century.
If used in cold weather, after a few days they cure in an incorrect manner
and do not develop optimum properties in the wood. Early in 1991 the genius in the research department of Smith & Co.
discovered the fundamental reason why this is so, and discovered Smith's
Dual Synergistic Catalyst™ which makes it possible for these resin systems
to develop a full and predictable cure at temperatures down to 28°
F, slightly below freezing! The entire formula was redesigned to take advantage of this new technology.
The new formulation behaves essentially the same in freezing weather as
Smith's Warm Weather Formula™ does in moderate weather. Smith's Cold Weather
Formula was designed to absorb as much water as the existing system does
from wood or osmosis-damaged fiberglass laminate, and in addition to dissolve
the ice crystals that form in damp materials subjected to below-freezing
conditions. The product line was further improved in 2001 when the solvent formulation
was upgraded to give a 50% increase in moisture-dissolving capabilities. Smith's Cold Weather Formula of Smith's Clear Penetrating Epoxy Sealer
mixes one-to-one by volume as does the Warm Weather Formula. Once mixed,
it is recommended that the product be used within its "pot life",
although it will be fluid for much longer. Smith's Cold Weather Formula of Smith's Clear Penetrating Epoxy Sealer
(CPES) was designed to be used in the temperature range of 28° F -
65° F. The table of pot life and full cure times below
illustrates this. It is a necessary part of the wood restoration process
that the solvents be allowed to evaporate out of the wood before paint
or filler is applied. The solvent blend in Smith's Cold Weather Formula
evaporates about as fast in cold weather as the solvent blend in Smith's
Warm Weather Formula does in warm weather. The solvent blend of Smith's Cold Weather Formula has a milder odor,
as well as evaporating about six times faster. These features allow restoration
work to be completed sooner and to be done in the winter, when most products
do not work properly. Restoration of wood inside a house, such as in a bathroom, a door threshold
or the inner part of a window sill, should be done with Smith's Cold Weather
Formula rather than Smith's Warm Weather Formula when the house is occupied,
due to the much milder odor and more rapid solvent vapor dissipation of
this version. Nighttime temperatures are usually much less than daytime temperatures
and so night provides less progress towards full cure than day. This makes
Smith's Cold Weather Formula valuable when the daytime temperatures are
in the 50° F ~ 60° F range and/or night temperatures are in the
30° F ~ 40° F range.

weather-related damage to exterior wood.
Here's how it works:
"(We've handled) window sills, decking, (and) porch dry rot. (It's)
a very empowering product-having taken us off our dependence on "handy-people" who
have charged us too much for too little in such repairs, i.e., inferior results.
Homeowners-You can do this." L. M. G.
Water selectively
penetrates the sound portion of wood. Smith's Clear
Penetrating Epoxy Sealer™ (also known as CPES™)
selectively penetrates the deteriorated parts of wood. In other words, it finds the rot. There is actual SCIENCE here.
No other product uses my science.
None.
The science is why it works.

Here's What Professionals Need to Know:
Section IV, paragraph 8.6 of
Restoration of Rotted Wood with a Flexible Penetrating Resin.
The natural
porosity of sound wood is almost entirely sealed by a single impregnation with
Smith's
Clear Penetrating Epoxy Sealer. This is another reason why it cures paint
failure. See what it does to a common building siding, T1-11 plywood:
T1-11 Plywood Impregnation.
Smith's Clear Penetrating Epoxy Sealer is the only product made largely from the natural resins of wood itself. It creates a tough,
flexible resin system that moves with the wood. It allows the wood to "breathe" so excess moisture does not accumulate
behind it, promoting paint-failure and ultimately rot. The experiments that demonstrate this are in Chapter 3.0, Section II,
Restoration of Rotted Wood with a Flexible Penetrating Resin.
Paint or varnish is glued to the wood with its flexible epoxy glue that stretches and bends almost identically
to natural wood. The proof of that is in the mechanical tests in Section III of
Restoration of Rotted Wood with a Flexible Penetrating Resin."I've been in the 'Period House' restoration business for more than 25 years,
and to save old windows and doors and other period house architectural items, I learned real early that
just because there was some rot, I did not have to throw out a window sash or architectural trim, if I
use Smith's Clear Penetrating Epoxy Sealer (CPES) and Smith's Fill-It Epoxy Filler.
I could not stay in business without Smith's epoxy systems." David T. Clark - I Do Windows
And Doors-Sacramento CA 916-498-1570
Smith's Clear
Penetrating Epoxy Sealer™ (CPES™) consists of a tough, flexible resin
system in a solvent blend which dissolves the sap, oil and moisture found
in wood. The resin system is derived from natural wood resin and develops
a chemical adhesive bond to the wood fibers themselves.
The wood is strengthened while allowing normal expansion and contraction
with changes in temperature and humidity.
When repairing wood that has mild dry rot, the CPES will migrate along
the abnormal porosity which dry rot fungus creates within the wood, as
long as it continues to be fed in. Impregnation of wood with CPES changes
the cellulose of wood (which fungi and bacteria find tasty and easily
digestible) into epoxy-impregnated cellulose which resists further attack
by fungi and bacteria while reinforcing the wood, accomplishing restoration.
Paint or varnish will last longer because the paint has a strongly attached,
chemically compatible surface to bond onto.
Read and follow application instructions. Keep rain or dew away from areas
being treated with CPES until solvents have evaporated out of the wood.
This will take at least a day and may take a week or more, depending on
the extent of deterioration, how deeply the CPES soaked in and the temperatures
day and night.
Application may be by brush, roller or immersion. Spraying is not recommended
as a portion of the solvent component will evaporate in transit, and it
is important that the product be applied to the wood in the same formulation
furnished originally. When applying by roller on a vertical surface, hold
the roller only horizontally and slowly roll only upwards. When treating
rot inside sound wood, drill a hole that intersects the rot, glue a funnel
in the hole, and use Smith's Cold Weather Formula™ to impregnate the region.
Allow sufficient time for solvents to diffuse and evaporate out of the
wood before applying fillers or glues. Removing paint from all sides of
wood to be treated speeds solvent evaporation, as does moving air.
CPES is also a consolidant for old, crumbly concrete or mortar between
bricks, and is an essential component of effective osmosis blister treatment
on fiberglass boats.
