I am doing a clean and seal job on a slate floor- I'm not exactly sure what type of slate it is, only that it is a blue/grey color with a little bit of texture to it. We've acid washed it with a green nylon scrub brush. The cleaning process is causing quite a bit of slurry, I believe due to the aggressive brush. Normally I could put a nice solvent based color enhancing sealer on it and it would take the chaulky look away. In this case we are limited to using an immpregnator sealer which leaves the slate with the chaulky look which the customer is unhappy with. Any ideas on how to get rid of the chaulkyness?
