Nei,
not sure what the paint is, but just before xmas I had a call ,custy knocked full tin of paint over whilst decorating.
I advised to leave ,apart from carfully scaping any he could up , woth out spreading the problem.
then advised to keep moist, and would go straight round next morning.
Believe it or not my first aproach was a simple cold water extraction with hand tool , and out it came. a very relieved custy, and job to do more work booked in.
so worth a try
