How to Clean and Seal Travertine Tile and Grout

This client got in touch about cleaning their Travertine Tiled floor which they were struggling to get clean. They had been using all the usual household floor cleaners, but nothing was having the desired effect. The property was in the lovely village of Sunbury On Thames within the borough of Spelthorne. I’m based in nearby Shepperton and so it wasn’t long before I was able to pop over and take a look at the problematic floor.


It turns out the Travertine floor which was installed throughout the hallway and kitchen had not been professionally cleaned since its’ installation twelve years prior. As you can see from the pictures, the old sealer that was protecting the Travertine had long since worn off and this in turn had allowed soils and spillages to penetrate deep into the pores of the stone and grout. The sealers demise may have been accelerated with the use of overly strong cleaning products but given it not been professionally cleaned for twelve years it was well overdue a deep clean and reseal.

I discussed with the client what we could do to clean the floor and demonstrated my proposed cleaning process on part of the floor. They were very satisfied with the demonstration and were happy to go ahead with my quote. The work would take two days to complete, one day for cleaning and a second day for sealing.

Deep Cleaning a Travertine Tiled Floor in Sunbury-on-Thames

Working in sections I started by spraying a strong dilution of Tile Doctor Pro-Clean on the floor and left if to soak in while I set up a floor buffing machine with a black scrubbing pad. After about ten minutes I ran the buffing machine over the working area, the machine was set to run at slow speed to reduce splashing. This action broke down the soils and helped lift the marks and stains out of the stone.

Tile Doctor Pro-Clean is a concentrated, multi-purpose high-alkaline cleaner, stripper and degreaser. The strong dilution of one-part cleaner to two parts water would ensure it would clean the floor and strip off any old sealers present on the tiles. Once the Travertine had been cleaned in this way, I ran a narrow brush along the grout lines to ensure they were also scrubbed clean.


After scrubbing a low-pressure rinsing machine was used to rinse the floor with water and extract all the dirt and cleaning products off the floor. After a final inspection the floor was then left to dry out overnight to leave the stone ready to receive a new seal the following day.

Sealing a Travertine Tiled Floor in Sunbury-on-Thames

I returned the next morning and tested the floor with a moisture meter to ensure the Travertine was dry. The results were good, so we set about applying two coats of Tile Doctor Colour Grow which is a colour enhancing sealer that soaks into the pores of the stone thus preventing dirt from becoming ingrained there. The sealer really brought put the contrast back into the stone by enhancing the colour whilst giving it the protection it needed to prevent future spillages staining the tiles.


The client was very happy with the result, the finished floor looked much lighter and 100% cleaner, the beauty of the natural stone was really apparent, and the grout which was once dark and was now white again.

For aftercare I recommended they avoid purchasing supermarket floor cleaners, the majority of which are too strong for sealed stone and let them with a bottle of Tile Doctor Neutral Tile Cleaner. This is a pH neutral solution that will not prematurely erode the sealer and is highly concentrated, so a small bottle lasts a long time.
