AAARRRRGGGGGG!!!!!! Holy mother of God - note to self, Sherwin Williams 'Oil' based decking stain and Cabot's SPF are going to be charged at a much higher premium next year!!!! That SPF crap is brutal to strip!!! And after stripping it - I am convinced that Sherwin's oil based deckscapes must have acrylic in it as well.
With a pump up sprayer I mixed up two gallons of F-18 mixed 12oz/gallon - pretty hot mix, right? Wrong - after 3 sequential applications over an hour and half on a very moist overcast day yesterday - didn't even touch it!
Thankfully I ordered a 5'er of butyl from the chemistry store a month ago and had it on hand with some HD-80. Mixed HD-80 at full strength and amended it with butyl and extra NP-9 surfactant. Applied it once - started seeing results after 20 minutes and then re-applied a second time - and that's when it really started to lift. Still the stain was never truly emulsified - it just lifted off the wood and was a goobery mess as I was rinsing it off.
Homeowner had tried to strip and brighten themselves with the store bought stripper and couldn't get it off. 5 separate applications of stripper - and the most soapy mess of a rinse off that would just never completely rinse - the applications of F-18 that went directly into the wood I think is to blame? What an F'ing nightmare - but at least it's off. You aren't a true deck restoration specialist until you have tackled SPF. That stain is a nightmare!
It is some really tough stuff! But the way it fails - you can't maintain it at all. If they could find a way for this stuff to fail 'evenly' - this would be a great stain
