Recommendations for outdoor wood preservative to apply...
We have an old wooden house and whenever, I remove/repair clapboards or
trim, I would like to be able to apply via either spray or brush some type of long-lasting wood preservative. I would apply this both to any old wood exposed and any new wood added. I know in new construction, people spray on various borate solutions. Any specific products to recommend that are readily available (without requiring certification or license)? |

Those of us that live in log homes know these products pretty well. Just be aware that any of these products only work on bare wood. They rely upon absorbtion, to penetrate the wood and offer the protection they promise. Any existing finish on the wood will prevent that, and the product will simply wash away in the next rain. -- -Mike- |

Mike, I'd be very interested in hearing about your log house experiences either here or privately (use "reply to sender" for address). My wife's mother and step father built one here in Central Florida in 1996. He is was the GC. He was/is an incompetent idiot and shoudn't be qalloed within a half mile of any construction project. Long story short, wife's mother died, step father neglected things like insurance, taxes and maintenance so my wife now owns the house and we are faced with the project of getting it into decent enough shape to sell. First floor is cedar logs, second story conventional. Outside second floor is board and batten cedar. Neither has ever seen any preservative, water repellant or paint. I told him he should apply, he said, "No, we want it to weather natural". Oaf. Well, it "weathered natural". Board & batten is badly checked/split/warped/split. Logs have deep splits and are a nasty, dark brown-black but otherwise OK with the exception of the corners...some water penetration (to inside) at the corners. He tried to mitigate all by smearing caulk around. It did nothing except act as a wedge to further the splitting. Oaf. Board & batten will probably be ripped off and replaced with vinyl. Kinda reluctant to do so because I fear what we may find...we just replaced 18' of stud wall - including 2x12 SYP beam - under a couple of upstairs windows because the whole wall from window bottoms to top course of logs was badly rotted. Rot was caused because the windows were sitting on a flat "sill" and that sill didn't extend outward far enough to cover the sheathing. Oaf. Mainly, I am interested in your experiences with the log part. The corner problem probably arises from the necessity to lop off the tongues there and improper caulking. Any ideas to fix? Ditto the water stains on the interior? Overall (topical materials)? BTW & FWIW, you can make your own boron preservative at a tiny fraction of the $60-70 per gallon from your link, see below sig. Biggest problem with any of the boron things is that they are water soluble. Which is why I jealously guard my last remaining part of a gallon of copper napthanate -- dadiOH ____________________________ There are two commonly available inexpensive materials that will kill rot in wood and prevent its recurrence. First, there are borates (borax-boric acid mixtures) which have an established record in preventing rot in new wood and in killing rot organisms and wood-destroying insects in infested wood. Second, there is Glycol, most readily available as auto antifreeze-coolant. Glycol is toxic to the whole spectrum of organisms from staphylococcus bacteria to mammals. Ethylene glycol and propylene glycol are clear liquids used in antifreeze and deicing solutions. Exposure to large amounts of Ethylene Glycol can damage the kidneys, heart, and nervous system. Propylene Glycol is generally regarded as safe for use in food. Antifreeze that is sold as "Earth Friendly", "Environmentally Safe", etc are generally based on Propylene...Make Sure You Buy The Propylene Glycol, NOT the Ethylene!!! Source of Information : Agency for Toxic Substances and Disease Registry (ATSDR). 1997. Toxicological profile for ethylene glycol and propylene glycol. Atlanta, GA: U.S. Department of Health and Human Services, Public Health Service. _________________ Both borate solutions and glycol penetrate dry and wet wood well because they are water-soluble; in fact, penetration by glycol is especially helped by its extreme hygroscopicity -- its strong attraction for water. For both, the fact that they are water-soluble means they are not permanent solutions to rot in wood that is continually exposed to water-below the waterline and in ground-where they will eventually be extracted-dissolved out. I have had good results by adding a water soluable "Sealer" to my solutions which make them more water resistant. There are two types of borate products commercially available for treating wood, Tim-borŽ).. A powder you mix with water and spay apply to all wood including studs, crawl spaces, subfloor, rafters and exterior sheathing. It provides a termite and rot resistant envelope treatment that can last for 30 years or more. Treating an existing problem is best done with Bora-CareŽ).. It is a liquid concentrate that is mixed with water and sprayed on the affected wood and all of the wood surrounding that area. A solution of Tim-bor can also be used if the wood has a moisture content of 20% or greater. Their equivalents and more concentrated solutions can be easily prepared from borax, boric acid, and antifreeze at much lower cost. Glycol by itself has one big advantage over solutions of borates in water. Glycol penetrates rapidly through all paint, varnish, and oil finishes (except epoxy and polyurethanes) without lifting or damaging those finishes in any way. You can treat all of the wood without removing any finish. Once bare wood has been treated with glycol or the borate solutions and become dry to the touch it can be finished or glued. If a borate solution leaves white residues on the surface, it will have to be washed off with water and the surface allowed to dry. Glycol's toxicity to humans is low enough that it has to be deliberately ingested (about a half cup for a 150 lb. human); many millions of gallons are used annually with few precautions and without incident. It should not be left where children or pets can get at it, as smaller doses would harm them. The lethal dose of borates is smaller than of glycol, but the bitter taste makes accidental consumption less likely. BORATE WOOD PRESERVATIVES: COMMERCIAL AND HOME-BREWED Commercial: Tim-BorŽ: Solid sodium octaborate; dissolves in water to make approx. a 10% solution containing 6.6% borate (B2O3); about $13/lb. Covers about 200 sq ft. Bora-CareŽ: 40% solution of sodium octaborate in ethylene glycol; 27% borate content; $90/gal. for the concentrate. Home-Brew Water Solution of Borates: Based on U.S. Navy spec. of 60% borax-40% boric acid (this ratio gives the maximum solubility of borates in water); #1. This is equiv. to Tim-BorŽ... 6 parts of borax and 4 parts of boric acid. To prepare one gallon of a 10% solution, start with an oversize container (larger than 1 gallon ) add 1 lb. of powder to appx 3 qts of water agitating until the powder has dissolved, then add additional water to end up with 1 gallon of mix. To prepare a 15% solution, add 1.5 lbs. of powder, then add the remainder of the water and mix as previously. Approximately 1 gallon of solution will be needed to treat 200 square feet of wood surface area. (Note: solutions should be used immediately and not stored.) . EXAMPLE: Prepare 5 gallons of 10% solution: Add four (4) gallons of clear, warm water to a six-gallon bucket. Add five (5) lbs. of powder while gently stirring. Add enough water to bring the final volume to 5 gallons, and continue to stir until all of the powder has dissolved. Agitate the solution briefly at the beginning of each spray job, or after the solution has been standing for an extended period. Do not spray or spill onto soil or foliage. Apply two applications of a 10% solution to wood surfaces by brush or spray. Apply one application of a 15% solution to wood surfaces by brush or spray. Applications may be made to wood structures including decks, fences, steps, sheds, barns and other out-buildings. #2: This is equivalent to Bora-CareŽ Prepare the concentrate: Mix 1 Gallon glycol antifreeze, 4 1/2 pounds borax, 3 1/2 pounds boric acid. Mix the ingredients and heat till boiling gently. Boil off water until a candy thermometer shows 260°F. This removes most of the water of crystallization in the borax. This solution is stable at 40°F and has a borate content of 26%. This is equivalent to Bora-CareŽ at about $90/gal. for the concentrate. The concentrate must be diluted with an equal volume of water before being applied. Application: Add 1 gallon of water to every gallon of concentrate and stir thoroughly until solution is completely uniform. Always use diluted within 24 hours after mixing. If kept for longer periods of time, the active ingredient can drop out of the solution. Note: is toxic to plants and shrubbery; if necessary, cover plants, root systems and surrounding soil with plastic to avoid contamination. Apply only to bare wood. Remove any finish or water repellent coating before applying . Wood surfaces should be free of dirt and other contaminates. Apply diluted by spray or brush to all exposed wood surfaces. It may occasionally be necessary to apply more than one coat of to attain the recommended application rate. This is especially true for larger, smooth surfaced wood members. Wood surfaces should be allowed to dry for at least 2 hours between applications. Do not apply in the rain or snow. If inclement weather is expected, protect exposed treated surface with a plastic tarp for at least 24 hours after treatment. One gallon of concentrate will treat up to 800 board feet of wood. Only diluted should be applied to any wood surface. Prior to application, check wood surfaces for an existing water repellent finish by spraying a small amount of water onto the surface of the wood or logs. If the water beads up or is not absorbed into the wood, a finish is present which must be removed before applying the diluted solution. |

Anything that lists borax as the contents. I don't know if 20 Mule Team Borax has anything else in it or not, label should say.

Or is there a more cost-effective, easily-available source? Probably, the "roach powder" also has something added - flour, sugar - to act as bait.

Or is there a more a cost-effective, easily-available source Regular anti-freeze is ethylene glycol. It is quite toxic, especially if ingested. Antifreeze that is sold as "Earth Friendly", "Environmentally Safe", etc are generally based on Propylene; still toxic to a degree, I think, but much less so. Again, the label should tell you. AFAIK, you can use either, just dont ingest them. - The instructions for the Bora-Care equivalent suggest boiling off water and then diluting with water before use. What is the reason for boiling it off and then adding it back? Is it needed for long term stability or is it just a way of making a lower volume concentrate? It is to get sufficient water out of the mix so that the mixture can get to 260 fegrees F. The purpose is to remove the "water of crystallization"...water which is necessary for the solid materials to remain in a crystalline state; once removed, they will go into solution and remain there when diluted later. Can I skip the boiling off step? NO! Thanks for the helpful replies... I will post back if I find any interesting or non-obvious sources of the above materials... |

I doubt the manufacturer of Bora-Care would help me understand their process so I could copy it and make my own DIY cheaper version :P Do you really know anybody here well enough to take their word over the direct advice of the manufacturer? No more or less than I trust the people here for any other advice... It's USENET, you ask a question, you get one or more answers, some seem helpful & knowledgeable, some less so, and some are more trolls. You use your judgment and see what makes sense. Frankly, trusting someone on understanding the basic chemistry of why you need to boil off the water first seems a lot less risky than trusting advice on even run-of-the-mill woodworking and home repair processes that could be dangerous to either you or to precious materials. Indeed, dadiOH promptly provided a logical and scientifically reasonable answer, so I am honestly not sure what was the purpose of your post... |

I can find it at the local store for $4 for 76 ozs (just shy of 5 pounds) -- clearly dirt cheap. I found Boric acid for $20 for 5 pounds at Grainger. HOWEVER, I am having a hard time finding pure (non-diluted) propylene glycol locally. I checked several auto stores and only found ethylene glycol antifreeze except for marine antifreeze but it was only about 50% concentration. I saw some sources online, but I was hoping to buy locally. Any suggestions? |

The company uses TimBor exclusively under houses.

Considering that: Borax is a mild & earth friendly detergent and that Boric acid is a pretty human-safe Roach killer and that Propylene Glycol is almost edible, I wouldn't think this would have any effect on life insurance. Also, at worst, this concoction will be a less effective version of Bora-Care, so I can't imagine the property insurance being upset that I treated something that otherwise would not even be treated. It's scary that we live in such a liability-scared society that people are frightened to use even minimally toxic ingredients... |

Well my guess is if MSDS says 25%, that is likely to be a lot closer to 25% than to 100%. I saw some stuff at one of the chain auto parts stores that was 50% in that the first ingredient was propylene glycol and the 2nd water -- but I would prefer it to have no added water... otherwise, I will spend forever boiling off the water plus the recipe ratios will be all off. When I have made the stuff, I used what was available. Probably the ethylene. Yes, long term and/or intimate exposure can do bad stuff to you - Well, since the warning labels on the ethylene glycol antifreeze say to avoid breathing the fumes and since the recipe calls for boiling off the water, I would be concerned about doing this anywhere indoors (which is the easiest option for me since the stove is so convenient...). So, I will keep searching for propylene glycol. BTW, it seems to be used on farms to feed animals to prevent ketosis. It appears to be 100% propylene glycol -- but we live pretty far from real farm country, so I am not sure that variety is locally available. Also, it is a lot more expensive than antifreeze... probably because it is (animal) food grade. |

More time, true, but once the mix reaches the required temperature the ratios would not be affected. What I meant is that if for example it is only 50% propylene glycol, then I would need to add 2 gallons rather than one of the antifreeze to end up with 1 gallon of propylene glycol... and if I don't know the ratio then I guess, I would have to try to boil off just the water in the antifreeze first to make sure I get a gallon of (almost) pure propylene glycol. _______________ When I have made the stuff, I used what was available.

No range hood with fan? Of course, but my wife doesn't like the 'smells' that come from the kitchen when I use the stove and oven for my "chemistry" (a.k.a. home repair) experiments. Plus the warning label was pretty scary and it's not like my oven hood is a real chemistry lab hood (though given that it is a Thermidor it probably cost *more* than a chemistry lab hood lol) Thanks for all the really helpful advice and replies |

It's $18.99 -- a bit pricey for antifreeze but I'll pay the extra to avoid the toxicity both in my kitchen and then on the wood... According to the MSDS, it's 94-96% propylene glycol, 3% water, 1% additives which should be close enough... An alternative is Durvet Propylene Glycol which is used to prevent ketosis in farm animals. It says it is 100% propylene glycol. Amazon has it for $21.77 plus shipping. More expensive, but presumably purer. http://www.amazon.com/Durvet-Propyle...0624595&sr=8-1 |
