I have painted hollow columns made of 3/4" pine and I would like to protect them with Bora care.
I plan to drill holes in all four sides near the top and spray the Bora Care in. Would foaming be better. What foaming agent and how much should I use in my 1 gallon Chapin sprayer?
Foaming would definitely be the best option for your scenario. You mix Bora-Care as you normally would at a 1:1 ratio (one gallon of bora-care with one gallon of water). After you mix it, pour the solution in the foamer and add Pro-Foam foaming solution. You want a high expansion foam so you should mix 7 to 10 oz. of Pro-Foam per gallon of bora-care solution that you make. Then close the lid, shake the foamer, and pump it like you would any other hand pump sprayer. The Chapin Poly Foamer comes with a coiled hose and ¼ inch tapered nozzle. You can get the Chapin poly foamer in a 1 gallon model or a 2 gallon model.
