The picture below shows a stone floor that was painted long time ago and with the time, the paint has been removed. It is very difficult to remove all the paint from the stone. In Cambridgeshire, we also find bricks painted in red as this was fashion several years ago.
For the removal of paint, oil and waxes on old tiles like this we use a specialist method where the treatment starts the day before the actual cleaning start. We call it Blanket cleaning.
This allows our clients to still have access to the treated areas till the next day when we start the cleaning as we will use a very thick plastic sheet covering the floor that is coverd with our specialist cleaning solutions...
here is a example of Pierre covering a floor...
