Restoring a Salt Satined Quarry Tiled Floor in Gamlingay

This quarry tiled floor in the village of Gamlingay had been subject to efflorescence salt staining over many years. This problem typically occurs in older houses where the floor has been laid without a damp-proof membrane allowing moisture to rise through the tile bringing with it salts from the sub floor. Gamlingay is located in South Cambridgeshire, near the border with Bedfordshire, is an ancient village which features in the Domesday Book. Not surprisingly a lot of the property here is quite old and includes sixty listed buildings.

Before the current owner moved in the property had been left dormant and empty with no heating which hadn’t helped the condition of the floor amongst other things. The white efflorescent salt staining was now very evident on the Quarry tiles and had caused a lot of damage to the surface of the floor. I discussed with the client how we could help and carried out a test clean. They were happy with the result and we agreed our quote to renovate the floor. We arranged to return later in the month.

Renovating a Salt Damaged Quarry Tiled Hallway Floor

The cleaning began with the application of Tile Doctor Remove and Go which was sprayed onto the tile and left to soak in for about ten minutes. The tiles were then scrubbed with a very coarse 200-grit diamond pad fitted to a rotary machine. The soil was then extracted using our van mounted hot water extraction system which makes light work of rinsing the floor and keeps the mess to a minimum. The combination of Tile Doctor Remove and Go and the coarse pad cleaned and resurfaced the tile improving the appearance of the floor and once the soil was removed you could really see the transformation.

We finished the cleaning process by giving the whole floor an acid wash using Tile Doctor Acid Gel. The acid dissolves the alkaline salt still present in the floor and removes any grout haze still present on the tile. Once this had been scrubbed in it was rinse off and extracted using the hot water extraction system as before. The floor was then left to dry out which due to the lack of damp-proof membrane was expected to lake longer than usual, so we decided to leave the floor a few days.

Sealing an Old Quarry Tiled Hallway Floor

We returned on a nice sunny day and first tested the floor with our damp-proof meter. This just tests the moisture levels in the floor to check they are to an acceptable level. If the floor is not dry the seal will not cure properly, and the process would be a waste. In this case the readings were fine, and I was happy the floor was dry enough to be sealed.

The client had requested the floor have a low sheen appearance and they didn’t want it to look too shiny. Given the floors history with Efflorescence however I needed to choose a sealer that would give the desired appearance but was also breathable to allow for moisture to rise through the tile. Trapping moisture under the tile with a non-breathable sealer can result in moisture spreading to the walls leading to rising damp.

On this occasion I opted to go with the application of Seal and Go extra which is breathable and leaves a subtle sheen appearance. The acid wash we gave the tiles should neutralise the alkaline salts and now the house was occupied the damp issues which had led to them occurring in the first place are less likely. I applied six coats of sealer, allowing each one to dry before applying the next.

Cleaning Quarry Tiles around an Indoor Residential Swimming Pool

Photographs below of a job we did cleaning and sealing the Quarry Tiles surrounding a residential indoor swimming pool floor tiles at a grand residence in Cambridge. As you can see from the photograph below the Quarry tiles and Grout was looking rather washed out and given their proximity to the pool extra care was needed to be ensure we didn’t contaminate the pool with dirty water from the cleaning process or chemicals, fortunately all our equipment is electrically isolated so that was not a problem.

Swimming Pool Tile Cleaning

Fortunately the pool was fitted with a cover so we made a start cleaning the tiles using a strong dilution of Tile Doctor Pro-Clean mixed 50/50 with NanoTech Ultra Clean which add tiny abrasive particles into the cleaning solution making it more effective. Working in sections the solution was left to soak into the tile and grout before being worked into the floor using a rotary machine fitted with a scrubbing pad running at slow speed to reduce splashing. This process removed any remaining sealer and cleaned the tile and grout up nicely, we used clean water to rinse the floor and a wet vacuum to remove the soiled solution making sure not to drain any solutions into the pool and re-treating any stubborn areas. This process was fairly tedious and took up much of the day but the results were well worth the effort.

The tiles were left to dry off overnight and we came back the next day to seal the floor using two coats of Tile Doctor Colour Grow which is an impregnating sealer that fills up the pores in a tile to protect it from stains whilst enhancing its natural colours.
