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.
Bora-Care can only be used on cut lumber/wood not any actual plant/tree. We would recommend to use Dominion 2L which can be applied directly where they are infesting in the stump and around/on the stump for carpenter ants. Be sure to treat around your home as well to prevent. Check out our Termite Guide for all the up to date tips on Termite prevention and control. We also have one for Carpenter ants here.
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.
