Using Coarse Milling Pads to Renovate Terrazzo Flooring in Cardiff South Wales

This owner of this property is an architect living close to myself in the centre of Cardiff. He approached Tile Doctor late last year about the restoration of a Terrazzo hallway floor. Having recently purchased the property which was built around 1910 with an aim to restore the whole house back to its original condition and he wanted to preserve as many original features as possible.

I went over to the property to survey the floor and carried out a cleaning test on a small part of the flooring to show him the potential result I could achieve. Whilst I was there, I measured up the Terrazzo which extended throughout the downstairs hallway and through to a matching section at the front of the property.

Happy with the result of the test clean I worked out a quote for restoring the whole floor, which was accepted, and a date set for the new year. The floor was one of many projects being caried out at the property which was unhabitable at the time so it would be just a question of picking up the keys and letting myself in.

Cleaning and Repairing a Terrazzo Tiled Hallway

My first task was to remove as much plaster and paint from the floor as possible with a sharp bladed scraper. Then I started scrubbing the floor with a very coarse 50-grit pad fitted to a rotary machine. The pad is applied with water for lubrication and run over each part of the floor several times. The floor is rinsed and extracted with a wet vacuum and the whole process repeated with a finer 100-grit pad and then a 200-grit pad.

Moving up the grits the next stage was to scrub the floor to remove staining with a 400-grit burnishing pad using a strong 50:50 dilution of Tile Doctor Pro-Clean. The pad was applied as before, rinsing and extracting once done and then moving up to the 800 and then 1500 grit pad.

As the floor became cleaner the cracks and damage to the terrazzo became clearly visible and so I started on repairing the cracks with a colour matched filler designed for this type of work. This was left to dry hard and sanded lightly until level with the floor.

The floor was then left to dry overnight, and I returned the next day to apply the last burnishing pad which was a very fine 3000-grit polishing pad to achieve the desired shine, also to polish out any light marks.

Sealing a Terrazzo Tiled Hallway in Cardiff

The sealer we selected was Tile Doctor Colour Grow which is an impregnator that soaks into the Terrazzo occupying the pores and preventing dirt from residing there. The sealer achieves a durable hardwearing finish and enhances the natural colours in the stone chippings it also ensures the dirt will remain on the surface where its easily cleaned away.

Once done I returned the keys, and the architect contacted me later to congratulate me on the restoration of the finished floor. For after care cleaning of polished Terrazzo I recommended the use of Tile Doctor Stone Soap which is a mild but effective floor cleaning solution that helps maintain the patina.
