Agreed. 4% is actually too much to use on deck tops, and dwell time has a lot to do with furring. Watch and learn from my master, @Racer. He preaches 2%, which I follow closely, with a dwell time that is short, using my deck-width fan from my XJet to clean, followed by an oxalic treatment. ALSO, check the experience of your teachers.

Who implied this? If you used the searchg function you might see a post where I exclaim the seemingly uselessness of rinsing brick. My teacher @Racer admonished that brick needs rinsing too. The point to make is that sometimes one must hit brick multiple times to eradicate mildew and algae.
My bad he was talking about bubbling soap…when I read too fast my mind plays tricks on me
I’ve never seen a brick harmed. In my area the brick can easily have as much growth as the siding. Brick gets treated the same as siding. Rinsing is necessary.

It doesn’t happen all the time, but if your surfactant gets sucked into the pores on the brick then you will ether be rinsing for a afternoon or your customer’s brick will look like it is dripping with soap whenever it rains.
I’ve heard that. I don’t use enough for that to be an issue for me. Almost all mine are 1/2 brick with the top half being hardy
Well said and best advice yet!
