Push the tile stripper across the floor.
How to remove paint from slate floor tiles.
Then wipe with a water dampened cloth to neutralize the surface.
Hi you could also use a buffing pad on an orbital sander.
You remove a coat of paint from a slate surface such as a floor or countertop just as you remove paint from wood use a chemical stripper.
Because slate has an irregular surface however scraping is more difficult and less efficient.
Mix up your cleaning solution.
Clean painted tiles with household cleaner or a 50 50 solution of white vinegar and water.
I have done a job for a client with a similar issue and we ended up using paint stripper followed by buffing the floor until no paint was left.
Try 1 2 cup fabric softener to 1 gallon very warm water.
You will have to either live with it or paint over it again.
Don your goggles and gloves before you.
However i am an optimist.
If necessary add a little water or more baking soda to make the paste thick but manageable.
Soak towels in it and put them on the floor.
This should form a paste.
Turn off the stripper to.
Remove a small amount of tile at a time so the old slate tile does not build up in front of the stripper and damage the machine.
As slate is soft you will be able to sand it off the slate before you reseal.
