Grout Cleaning

Welcome to my Work History archive where you will find detailed examples of the cleaning and renovation of Grout carried out in Nottinghamshire

Cleaning and Renovating Grout

The top layer of grout is porous and can absorb grease, dirt and limescale. Spillages such as wine, lemonades or greasy substances will cause marks and patches in the joints in the floor. Grout between wall-tiles particularly in damp areas like bathrooms will become dirty and unattractive as a result of Mould, Mildew and Limescale.

Mould is one of the most unsightly problems, which usually starts off in the wettest area of the room, this could be the bottom of the shower or bath, then starts to spread and if left unchecked could cover a large area of the wall.

Another common issue we find is a problem known as Grout Haze or Grout Smearing where a thin layer of grout has been left to set on the surface of the tile. Once grout has set it is difficult to remove.

Discolouration of grout joints in bath or shower areas due to continued use of acid formulated shampoos and soaps. This causes yellow orange and pink stains to the grout over even a short period of time. Whilst Grout Joints can be cleaned, badly stained grout may need to be re-coloured.

Protecting your grout in advance with a sealer will prevent most of these issues and although relatively unknown in the UK, protection awareness is growing. Sealing forms an invisible barrier between the grout and the surface, this will then protect your investment for years to come.

We have solutions for all the problems listed above and below you will find detailed examples of work we have carried out in the past to resolve many of these issues. It should give you some idea of what’s involved and what can be achieved with the right techniques and products.


Honed Limestone Tiled Floor in Bingham Before and After Cleaning

Grout Haze on honed Limestone tiles in Bingham

The photographs below are of a honed Limestone floor in the kitchen/diner of a house in Bingham, Nottinghamshire which had been contaminated with heavy grout haze from dark grout that had penetrated into the surface of the natural stone tiles due to the face that they had not been properly sealed prior to grouting. The customer had asked the tiler to rectify the issue, but without the proper equipment and knowledge he was unable make any impact on the problem and so we got the call.

Milling a Limestone Tiled Floor

Before starting we cleared any furniture from the area and masked skirting boards and kitchen units. We then set about rectifying the problem with a set of Milling Pads that which remove a layer off the surface of the stone; this also has the added advantage of removing any lippage issues between the tiles.

Milling natural stone flooring is a controlled process using water, and specially manufactured diamond milling pads. We have a special low speed rotary floor machine for this purpose which is weighted with 65kg to ensure the right level of tension on the floor.

A rotary hand polisher and oscillating multi-tool fitted with smaller milling pads were used to remove the grout haze from the wall edges and wall corners of the tiled kitchen. Once satisfied the contamination had been removed, then the floor was thoroughly rinsed with fresh water to remove the resulting slurry created by the milling process and then left to dry off overnight.

Sealing the Limestone Floor

The next morning I arrived to find the floor had dried out enough for me to seal it which was done using a couple of coats of Tile Doctor Colour Grow which is an advanced sealer from the Tile Doctor range that impregnates into the stone and lifts the natural colours in the Limestone floor as well as providing stain protection from both water and oils spills. Once the sealer had dried I then finished it all off with a quick buff using a white buffing pad.

After an hour of sealing the floor can be walked on, but impregnating sealers take up to 48 hours to fully care so care should be taken before the floor is subjected to normal use. For maintenance I recommended regular cleaning with a damp mop using a diluted solution (1:100) of Tile Doctors Stone Soap which is PH neutral and won’t affect the sealer.
