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.
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.
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.
The rate of Timbor in a 50 gallon tank is 75 lbs to achieve a 15% solution.
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.
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.
Yes, as long as the application of Tim-bor Professional is completely dry, you can use a latex or other paint/stain product.
Tim-bor Professional is labeled as non-corrosive so it will not cause metals to rust.
We would not recommend using a borate product such as Timbor or Boracare on the leaves since the product could potentially damage the leaves. These products are designed to be used on sturdier cellulosic materials such as wooden beams and slats. If you are not able to replace the infested branches, then you would likely need to have a professional company fumigate the structure.
