Resin Injection into soft wood
Hi,
I have been reading about a process of restoring rotten wood by soaking resin into the wood making it as good as new or better. Are there other options for replacing rotten ribs and frames other than traditional sawed or steam bent? (from the inside) Is there any truth to this process or just more smoke and mirrors? Thanks for the help on this question and the earlier one about boat repairs. Marshall |

Thing to remember about wood: From compost ye come and to compost ye shall return. It's just a matter of time. Lew |

Unless it's encapsulated in amber.

There are some low viscosity epoxy products on the market that claim to
restore rotten wood. A few of them do restore the compression strength but do not help the bending strength. They are great for salvaging antique porch columns, thresholds and window sills but totally useless for boat repair where the stresses are not all in compression. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Let's put that solution in the smoke and mirrors column. |

I've known several boat yard operators and pile drivers who use this method (for their own boats). Actually, the most common way is to use regular epoxy resin and thin it with acetone to the right consistency. I know of a couple rib repairs that are about 25 years old and still in place. Ed |

There have been products around since the 1950's which are good for treating planking but may not have the stength for ribs and beams. However you can always build in structural reinforcement with glass fibre, metal, wood, plywood, or some combination and have a repair which is stonger, more rot resistent, and more durable than the original. For example you can cut out the rot, drill holes, insert metal rods, and build up with resin or in some cases cement mortar. It all depends on what parts you need to repair. Watch the weight when replacing wood with non-wood substitutes. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

Well, I am making observations from experience. The family company manages a number (like over 1,000) older single family and duplex rentals, many of which have wood porches. We use a variety of epoxies to restore rotten porch columns where the local Historic Preservation committee insists that restoration match the original. We have found that it works fine for trim and column bases but will not hold up on railings, floor planks and other parts than may be loaded in bending. Epoxy stabilizes the wood and prevents further rotting but it has much lower tensile strength than the wood and is considerably less resiliant. Unless the part is reinforced with carefully aligned glass fiber it will not be up to the task. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

If you have any proof whatsoever that epoxy treated rotten wood regains strength please share it. This certainly goes against 30 years of experience as a boatwright spcializing in restoration. We'll wait right here. |
