The alpha product is good I only use it for testing purposes.
It turns purple and you have to work fast real fast.
It can stain very porous stones.
Stick with the iron out. Use it straight mixed with water.
Works well. Open area to 80/120 g sandpaper.
How old is shower floor.
Does drain work well.
Was stain there prior to refinishing.
