timbore verses boracare5/28
From a little reading it sounds like boracare penetrates dry wood better, but timbore is much cheaper. I have a bunch of cants yellow pine 6x8 up to 12x12 that have been stickered in my barn for years. I plan to re-cut most of them to cut any twists out then spray them with boracare or timbor and then put a finish on them before making a timber frame. Can I get by with timbor since it is cheaper. any recommendations on a finish for them? Best place to purchase timbor or boracare?
Please read the label for both. Note that both require substantial dilution with water. Note that both have human and environmental health hazards. Note that the active ingredient is the same for,both.
Boracare penetrates into, especially drier, wood better because it has a certain amount of glycol co-solvent compounds which help keep the active hydrolyzed boron soluble in moisture and thereby still diffusible. So if your timbers have been drying on stickers in your barn for years, boracare is preferable. However if the timbers are dry, and will be used in a timber frame where they will remain dry, why is wood preservative necessary? Once the wood surface is dry after application of either timbor or boracare finish can be as if the surface was untreated.
