Sticky Sealer Removed From Terracotta Tiles in a Brentwood Kitchen

This is a Terracotta tiled floor at a property in Brentwood that had been recently installed. Unfortunately, the tilers decided to seal the terracotta with a linseed-based sealer that hadn’t gone off and was still tacky to the touch causing it to trap dirt. I suspect they simply put too much down; however, I was surprised they used linseed as this is a very old-fashioned method of sealing terracotta when modern sealers offer far better performance.

The solution I offered was to strip the linseed off the floor, give the tiles a good clean and then re-seal with a modern based sealer designed for the job. Happy with my quote and relieved the problem could be resolved, we agreed a date to complete the work.

Cleaning a Terracotta Tiled Kitchen

To strip off the Linseed Oil I applied a strong dilution of Tile Doctor Remove and Go which is a powerful alkaline coatings remover. It was left to work breaking down the linseed for about ten minutes and then scrubbed in using a rotary machine fitted with a black 17″ pad. The soiling was then rinsed away with water extracted using a wet vacuum. This process had to be repeated several times before the floor was clear and I used several pads in the process.

The grout was then hand scrubbed using Tile Doctor Pro-Clean, these were small terracotta tiles so there was a lot of grouting to cover. Afterwards the soiling was rinsed off and extracted as before using the wet vacuum.

The last step in the cleaning process was to give the floor an acid rinse using a dilution of Tile Doctor Grout Clean-Up. It was scrubbed in with a deck brush to remove excess grout smears and neutralise the pH level of the floor following the use of alkaline cleaners. Once done it was rinsed away and extracted as before.

Sealing a Terracotta Tiled Kitchen

I left the floor to dry out for a couple of days, before returning to apply a new sealer which for this floor we had chosen Tile Doctor Colour Grow. This is an impregnating sealer that soaks into the pores of the tile preventing dirt from becoming lodged there and thereby protecting it from within. Colour Grow as its name suggests includes a colour enhancing formula that improves the lovely orange/red colours so ideal for Terracotta.

Made from clay, Terracotta is a porous material and so does need quite a few coats before its fully sealed. For this floor I needed to apply give coats of Colour Grow, allowing for each coat to dry before applying the next. This is a low sheen sealer which will give the floor a much more hardwearing surface and it really brought out the natural colours in the Terracotta.

My client was very happy with the difference and left the following 5-star review.

For aftercare I recommended the use of Tile Doctor Neutral Tile Cleaner, which is a pH neutral tile cleaner, it’s a gentle yet effective product that won’t impact the sealer.
