Earlier this year I received a message from a homeowner in the small village of Ashmanhaugh near Wroxham about their Terracotta tiled floor. The floor had been installed twelve years prior in a large conservatory sunroom extension and was now in need of a clean and seal.
I went over to survey the floor and could see the Terracotta tiles were modern 30cm tiles. They had been sealed with a topical acrylic sealer after installation, but the finish was now very dull, patchy and worn. It was clear to me that the sealer had worn off on most parts of the floor leaving it porous and exceptionally difficult to mop.
The grout lines were particularly discoloured mainly due to the use of various wet-look cleaning products used over the years. This type of maintenance product often just serves to glue dirty water into the grout.
I worked out a quote to deep clean the Terracotta tile and Grout and then apply a new sealer that would give the desired finish. My client was happy with the quote and being frustrated with the floor was keen to have it restored to its former self as soon as possible.
Cleaning a Terracotta Tiled Conservatory Sunroom Floor
I returned to the property on the scheduled date and started by cleaning the grout with a strong dilution of Tile Doctor Remove & Go. This was sprayed along the grout line and left to soak in for ten minutes. The product was then scrubbed in with a narrow wire-bristle brush to get the grout as clean as possible.
The whole floor was then cleaned using a Klindex Rocky rotary machine fitted with a Nylon brush attachment to work in a strong 3 to 1 dilution of Tile Doctor Pro-Clean. This process lifts the dirt and contaminants out of the tile turning the solution black. The floor was then rinsed with more water and the resultant slurry vacuumed away with a high-power industrial wet vacuum.
Next step was to give the floor an Acid Wash using a 10:1 dilution of Tile Doctor Grout Clean-Up. Doing this has several benefits which include further cleaning the floor including removing grout haze, neutralising the PH level of the floor after the use of alkaline cleaning products and lastly it improves adhesion with the new sealer. This was brushed into the floor, rinsed off with water and then extracted with the wet vacuum.
The floor was then dried thoroughly with the wet vacuum before being left to dry off overnight, this is particularly important as Terracotta being made of clay is very porous and tends to hold the moisture. The floor needs to be dry before sealing as it can cloud the sealer and result in a patchy finish.
Sealing a Terracotta Tiled Conservatory Sunroom Floor
Work the next day started by confirming the Terracotta was dry and ready to take a sealer. I use a damp meter for this and was able to confirm the moisture readings were acceptable.
Tile Doctor has many different sealers available and in this case Seal & Go was chosen based on the flooring material and desired finish. Seal and Go is a modern sealer containing acrylic polymers and provides a hard-wearing low sheen satin finish that will subtly enhances the natural colour in the Terracotta without the floor being too glossy. Five coats were applied with a 300-gsm split-filament microfibre cloth, each coat was allowed to dry before applying the next.
My client was delighted with the mid-sheen finish and please that the floor would be so much easier to keep clean going forward. On the subject of cleaning, I also recommended our Neutral Tile Cleaner which will keep the floor looking in great condition and will ensure the longevity of the newly applied sealer. It is a pH neutral cleaner so is mild enough to use daily if required.
Tile Doctor has a comprehensive range of sealers that cover all types of finish and materials; before having your tile or stone sealed its worth contacting Tile Doctor for advice and to ensure your using the right product for your requirements.
