We are applying permachink products/stain in a few days to our logs that are being blasted with a baking soda mixture. Will there be a difference in the appearance of stain if I brush on part of home and spray other areas with back brushing?
Yes, there will be a difference in appearence from brushing versus spraying, but if you do it right it can match. Also, I am concerned that you are using baking soda. I have seen it do some funny stuff to certin woods, like turn it green. Good Luck!
