Yes, as long as the application of Tim-bor Professional is completely dry, you can use a latex or other paint/stain product.
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.
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.
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.
The rate of Timbor in a 50 gallon tank is 75 lbs to achieve a 15% solution.
Tim-bor Professional cannot be applied to wood that is already finished with a stain, sealant, or paint. If the wood is pressure treated, there is no need to treat it with the product, however if you still would like to ,Boracare would be the product to use and expect it to absorb and dry slower than on raw untreated wood.
Tim-bor Professional can be mixed with water only. Once the area is dry you would then paint.

Once mixed, Timbor should be used or discarded within 24 hours.
If you are working with wood that has been treated with Timbor, you would use the same PPE that you would need for sanding and other woodworking. Ideally, you would treat lumber with Timbor or another borate wood treatment after final cutting has been done for best protection: Timbor is absorbed about 1/4 inch into the wood where it is applied.
