So my question is, is that fuzz on the wood considered furring?
Any suggestions on the process or the cause of the possible furring would be greatly appreciated.
You’ll get different answers from everyone you talk to. Here’s my $0.02:
Yes you fuzzed it. On that wood, a hand brush will fuzz it.
SH will just make it brighter by burning the wood fibers; won’t do anything to actually clean it.
Sodium Hydroxide will clean it but you need to need to go more like 1/2+ per gallon. Then you’re rinsing with literal garden hose pressure… if you even look at it funny, it’ll fuzz. An it’ll turn black so after rinsing, you’ve gotta put on oxalic acid to shift the pH back to earth. It’s terrifying and dangerous and I don’t recommend it.
Why not try sodium percarbonate? Put a couple gallons of warm water in a bucket, put in so much SP powder that it doesn’t totally dissolve, and apply it with a mop or sponge. Let it it a bit, then do it some more. Eventually, rinse it with a black (soaper) tip. If you do it on a mild and sunny day, most folks are blown away by how clean and bright (but not bleached) sodium percarbonate can get soft, finicky wood to be.
Hydroxide is only needed for stripping. It is the most likely to fur. If you don’t need to strip it use SH or sodium metasilicate or even percarbonate. SM and percarb are less likely to fur.
But all wood is different and sometimes it’ll fur regardless.
