When we bought the boat in December it was apparent that the outside would need to be completely sanded back, caulked and painted, with the winter we have just had this was a job for the future, well that time has come, I have been researching caulking a wooden boat, resins, paints, wood hardeners, preservers and treatments via google forums and various other sources in preparation for the job in hand, all my research kept coming back to one series of products developed by one man Steve Smith an American Scientist. CPES, clear penetrating epoxy sealer their filler fill it and their vitality treatments.
Until recently these products were only available in America however there is now a UK distributor based around the corner in Kent. I simply searched in google for the best primer for large wooden boats and how to caulk a wooden boat in google and youtube both searches pointed back to the same product CPES. I contacted the distributor this weekend to discuss the outside and inside, while we have the so much wood exposed it would be silly not to do as much now to help preserve the internal wood for as many years as possible.
I have ordered two large tins of CPES, Fill it, their filler that can be used instead of having to replace whole planks and their wood vitality for the internal beams horizontal and vertical.
The long working time (pot life) of these products mean they will retain their penetrating and moisture-dissolving ability for more time.
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 Formulaâ„¢ 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.
Our Epoxy Cleanup Solvent. will clean up any epoxy product before it cures. Once cured, no clean-up solvent is effective.
Working in cooler weather?
Use Smith's Cold Weather Formula™
The Cold Weather Formulaâ„¢ 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 Catalystâ„¢ 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 Formulaâ„¢ 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 Clear Penetrating Epoxy Sealer will prevent freeze-thaw damage to concrete. This surprising performance was discovered by a customer in Finland and verified by the National Testing Institute.
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 on the next page 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.
Smith's Fill-It Epoxy Filler™ now has a new, softer consistency!
Same great long-working-time. Same great hang-in-place performance. Same great ease of sanding or carving. Same great cold-weather-cure. Same great price. When you want the very best: Smith's Fill-It.
Hello. I'm Steve Smith. Thirty-five years ago I invented The Modern Technology That Restores Deteriorated Wood. Fill-It is an essential part of that technology. It works for two reasons: It is about as flexible when cured as the wood itself, and my resins are made largely from the natural resins of wood itself.
Using something that works isn't just a good idea, it's a necessity. We invented it. It's a fifty-fifty mix. It comes with simple directions. You can buy it. You can use it. Call, e-mail or write to 5100 Channel Avenue, Richmond CA 94804-4646 for more information. We can answer your questions.
