Yes, you can apply Bora-Care to wood that has previously been treated with Timbor. The previous application of Timbor will have no affect on the absorption of BoraCare into the wood. Since both products are borate-based and become one with the wood after application, there should not be any issues. You don't need to do anything to the wood unless you had applied any type of paint, sealant or stain after you applied the Timbor. If you had applied a sealant/paint/stain then you would need to strip the wood back down to it's raw state.
To use Bora-Care on stained wood, you would need to either strip and sand the mantle to its raw wood state or drill holes into the piece and use the gel formulation of BoraCare called Jecta. If sanding the wood to its raw state, BoraCare would be applied at the 1:1 ratio and after it has dried you can re-stain/finidh the mantle. Jecta is a ready-to-use injectable borate gel used by pest management professionals to protect sealed or inaccessible wood from termites and other wood-destroying organisms.
Mold on rough cut pine should not affect the efficacy of Boracare, if you do need to treat for mold, we recommend to use Boracare with Moldcare instead. If the wood is part of an outside structure, we do recommend staining it to lengthen the life of the wood and the efficacy of the product, however you do no have to.
Bora-Care should only be used on raw cut wood not any tree stump.
No, BoraCare with MoldCare will not hinder the staining process. We do recommend you speak to the manufacturer prior to use if you are doing the bleaching process as we are not familiar with it. You may contact Nisus directly on their contact page: https://nisuscorp.com/customer-service
Yes, Bora-Care would be applied at a 1:1 ratio to the areas where you have activity. The 1:1 ratio is for curative treatments, for preventative you would apply at a 3:1 or 5:1 ratio.
Please review page 5 and page 10 on the product label for dimensional lumber information. 2 coats may be needed to ensure the Boracare absorbs all the way through the beam.
Bora-Care should be applied by a hand pump sprayer or painted on as suggested on the label. Bora-Care is a very thick product and when applied through fine nozzles like a mister or a paint sprayer, it has been known to clog the nozzles on these sprayers. It is meant to be applied through larger openings in hand pump sprayers or painted on.
If the wood that was treated with Boracare was kept out of the outdoor elements so that rain couldn't wash through the wood, and pull some of the Boracare treatment from it, then you would not need to treat the wood again. Mold is a surface issue caused by excess moisture in the surrounding environment. If the mold on the surface has been removed and cleaned, and the environment you plan to use it within will have the wood either protected from moisture or will be sealed after building, you wouldn't need to worry about mold unless a new moisture issue arises. If you feel mold may become an issue again in the future, you may want to use the Boracare with Mold Care to treat the logs with to help prevent against mold in the future, as well as reinforce the original barrier you may have applied with the Boracare 2 years ago.
We do not advise to mix any waterproofing product, paint or sealant in the same tank mixture when applying BoraCare. A topcoat with a water-resistant finish such as paint, stain or water sealant is recommended within 6 weeks of the initial BoraCare application for longer performance. This can be done as soon as 48 hrs after the application provided the wood is compltely dry.
BoraCare is applied at 1:1 ratio for curative treatments and a 5:1 ratio for prevenative treatements.
Please review the full product label for more detailed information.
The dry time for Boracare is entirely dependent on how heavy you sprayed, the mix rate you used, and how quickly the raw wood you treated can absorb the product. This can be anywhere from a few hours to a few days.
Bora-Care can only be used on raw, untreated, unpainted wood for curative and preventative treatments against termites and other wood destroying insects. It has no efficacy or ability to treat termites in the soil.
If termite activity has been seen in the home, you will want to treat by doing Termite Trench Treatment directly against the foundation of the home using Taurus SC. Taurus SC can eradicate an exisiting termite colony within 90 days and provide a 10 year barrier protection against future termites when done correctly.
Please view our How to Treat for Termite Guide for more information.
For best results, it is recommended to treat all accessble sides of the wood with the Bora-Care solution to ensure the solution absorbs completely through the wood.
If you are treating wood with Bora-Care that is exposed to rainfall and that cannot be sealed, then yes, you likely will want to reapply the Bora-Care every 3-5 years as needed.
The shelf life of Bora-Care is 3 years if stored in a cool dry area out of any sunlight or extreme temperatures. Keep in mind that once the product has been diluted, the solution should be used or discarded within 24 hours of mixing.
No, for Bora-Care to work properly, it would need to be applied to raw wood only with no paint, stain or finish on it. Please be sure to review the product label for more information and complete application instructions.
Instead of Bora Care, if you are unable to strip the paint, you may want to consider using a product like Jecta into inject into the wood. You may view the product label here.
