Glasgow, Woodside Grade A Listed building.
A Large Mansion floor in Glasgow, The floor had been covered with latex screed and carpet adhesive, an intensive and time consuming cleaning procedure was carried out removing the latex and carpet adhesive by hand with very sharp blades used on an oblique angle = removes the latex but leaves the tiles unmarked.
Once only a thin skin is left a series of cleaning pads are used going from a very rough grit to a polishing pad.
the cleaning takes place over in this case two days, the floor is mopped between each procedure to ensure that none of the dirty residue soaks into the tile.
my method is tried and tested for over 4 decades and has stood the test of time.
when the floor is finally clean it is allowed to dry out for at least 2 days, then we seal with our preferred sealer = Dry Treat which has proven to be the best type for my restoration work.
the colours are enhanced however the finish is matt and the tiles are now able to repel oil & water borne stains.
I have projects which are as good now as there were when we sealed them 25 years ago,
