I visited the property to take a closer look and to take some moisture readings because these old floors don’t have a Damp Proof Course and moisture levels too high can restrict when this type of work can be done due to the sealers needing the floor to be dry in order to cure. I also did a test piece to show the customers what level of cleaning could be achieved.
Cleaning a Victorian Tiled Hallway
With the customers happy with the quote I returned to complete the work starting by covered the skirting and bottom of the stairs to protect the paintwork and carpet. I then put a strong stripper/degreaser called Pro Clean on to the floor, ensuring even coverage and keeping and eye on the floor to make sure that it didn’t dry out.After a short dwell time I set to work scrubbing the floor with a 400 grit diamond burnishing pad and using small hand blocks to get into the corners and any edges not reached by my machine. Once I was satisfied that the tiles were as good as they could be I rinsed the floor to remove the alkaline cleaner and soiled water.
This was followed by giving the floor an Acid rinse using Tile Doctor’s Acid Gel, this process counteracts any alkaline salts that can rise up through the tile as it dries out, a process which is more commonly known as efflorescence. This can be quite a problem on floors like this that don’t have a damp proof course (floors generally didn’t pre-1950s). I had to be careful not to leave the acid down for too long because these tiles are susceptible to acid damage.
Dealing with salt issues on these old floors (efflorescence) is essential because they can damage the sealer or become trapped under it, detracting from the beauty of the floor. Given the age of the farmhouse it’s difficult to know what the floor had been laid onto. Often it was compacted rubble and building works from the erection of the adjoining buildings; additionally some of the later Victorian floors were laid on a wet limecrete scree which contain a high salt-content.
Before I left for the day I left an air mover on the floor to aid in the drying of the tiles. If there are radiators in the area I also suggest that they are turned on overnight to further aid the drying process. Occasionally these types of floors need to be left for several days to dry but it is worth the wait and the floors can be used in the meantime provided indoor shoes and socks only are used and care is taken not to get the floor dirty.
Sealing an Old Victorian Tiled Hallway
Upon returning the next day I tested the moisture content of the floor and was pleased to find that it was well within acceptable levels for the application of the sealer that I was planning to use. I quickly checked the floor for areas that I felt may be able to be improved and once satisfied a single coat of matt-finish, colour-enhancing sealer called Colour Grow was applied before two coats of a Seal and Go sealer was used to give the floor a satin finish, which I think gives it a slight glaze and freshly mopped appearance.The customers were thrilled and said that they wished they had brought me in sooner!
