Did you pressure wash and scrape the wood after you applied Tim-Bor? If so, you may have removed much or all of your Timbor treatment. Tim-bor should be applied until the surfaces are wet but not to the point of runoff, and it absorbs about ¼ inch into the wood. If you are treating wood that is exterior wood or wood used for decoration or furnishing that will be stained or painted, then it would best to use Boracare to treat the wood before finishing it. Boracare is the liquid version of Timbor, it absorbs more thoroughly into the wood, and it dries clear and smooth when applied correctly.
Timbor will only penetrate 1/4 of an inch into the wood and will leave a visible white residue on the surface. You may simply dust it off before applying the stain. If you are wanting a product that does not leave a white residue and absorbs completely through the wood, we recommend BoraCare. BoraCare will penetrate all the way into the wood and will not leave a visible residue on the surface.
Timbor is not labeled to be used in this manner, and we can make no recommendations on this usage. Should you have any further questions feel free to contact the product manufacturer, Nisus, directly at 800-264-0870.
Yes you can use the dip method when using Timbor however, you will still be getting the same 15% solution rate as you would if you were spraying it on and getting the same 1/16" penetration level as well. To get the full penetration all the way through the wood we recommend using Boracare. Yes, you would want to get the surface powder left behind by the Timbor off the wood before using any finishing products.
It is recommended that you use a sealant or paint on the wood treated with Timbor. This will seal the product into the wood so that it will last for the life of the wood. It is not necessary to paint or use a sealant though.
Timbor is safe around wildlife and/or pets when it is used as directed. While you are doing a treatment, it is recommended that pets/wildlife out of the area until the product has dried completely. It should also not be used directly in sitting water. Timbor is used around structural wood so it should not come in contact with wildlife or pets.
Timbor may leave behind a white residue. If you think it may come into contact with the windows or hand rails while you are applying it, it would be best to cover them just to be safe.
It is fine and very common to add a spray indicator dye to Tim-bor or similar wood treatment products before spraying. This helps to keep track of what wood has been treated, and it does not interefere with the efficacy of the Tim-bor. Keep in mind that the spray indicator will not fade on the wood: it will be visible permanently.
Timbor is only designed to be applied to wood and does not treat mildew/mold. We would not recommend applying it to canvas.
Timbor will not kill any actively growing mold. It is a wettable powder for prevention of wood boring insects and fungi, that leaves a white residue on wood surfaces after it is applied and would not wash off wood surfaces. If you were to sand after application of Timbor it could remove the Timbor as it only penetrates approx. 1/4 inch into the wood. Since the product would not penetrate walls, you can remove from those surfaces using a wash cloth and water.
Tim-bor Professional is labeled as non-corrosive so it will not cause metals to rust.
We recommend that anyone other than the applicator stay out of an area treated with Tim-Bor until the application is completely dry. Though Tim-Bor should not have an odor when being applied, if there is any odor then the area should be ventilated before re-entry. You can view further safety information on the SDS here.
