This was a job I did earlier in May this year where I was asked to clean this lovely Limestone patio installed at the rear of a house in Haddenham near Thame on the Oxfordshore borders which had succumbed to the ravages of the English winter weather and was far from looking its best.
As a Tile Doctor and carpet technician I have invested a lot in powerful high pressure machinery that can make light work of interior and exterior installations so taking on this patio was not a problem and it was nice to work outside for a change.
Power washing a Limestone Patio
On arrival I set-up the high pressure equipment and then proceeded to pressure wash the patio in order to get the worst of the dirt out of the tile. Then I soaked the tiles in a strong dilution of Tile Doctor Pro-Clean which was left to dwell for thirty minutes. The next process was to use a deck brush to scrub the cleaner into the stubborn areas and then rinse the patio with clean water which was then removed using a wet vacuum. After letting it dry I then had to re clean the worst areas again following the same process until I was satisfied with the condition of the tile.
Sealing a Limestone patio
The patio soon dried in the warm sun and later that day I was able to seal it using a couple of coats of Tile Doctor Colour Grow which is a colour enhancing impregnating sealer that can be used internally and externally, it works really on Limestone and did well to bring out the natural colours in the stone.
Huge improvement, the owners must of been impressed by the difference and just in time for summer.
