Our Limestone Cleaning Process
Professionals begin by applying a Limestone floor cleaning chemical on the Limestone. The cleaner should be left to work for about 20 minutes to allow it to break down any greasy soil. We also use an industrial scrubbing machine to scrub the cleaners into the floor.
After the scrubbing stage, they clear away the cleaning slurry and verify the condition of the floor. We keep scrubbing and rinsing until the floor has released all the soil. On honed and polished Limestone, a single scrubbing and rinsing stage is normally enough to take off the ingrained sloil. Although, with Tumbled Limestone floors and Brushed Limestone tiles, the cleaning and scrubbing may require to be repeated several times.
After scrubbing, there may be soil trapped in the surface of Tumbled and Brushed Limestone, and the grout.
If there is some residual dirt after machine scrubbing, we can use hot pressure rinsing machines. Hot pressurised rinsing propels heated water deep into the pores and holes in the tiles and the grout, to get at the dirt that a scrubbing machine could not take out. It is often remarkable how more dirt the hot pressure rinsing process takes out.
Pressure rinsing may not be suited to soft or very porous Limestone, as it can certainly create a shadow pattern with the rinsing..
Limestone Polishing
Polishing Limestone will become necessary when the shine has worn off the polished Limestone through wear and etch damage.
Polishing Limestone starts with diamond honing to take out the surface imperfections and prepare the floor for diamond polishing.
Fine diamond grits makes a honed finish. If you prefer a gloss, after polishing, we use Limestone polishing powders to give the Limestone a high polished shine.
Limestone Restoration
Limestone restoration work commences by checking out the floor for any problems. Usually mopping with powerful cleaners and also shoe traffic degrades the surface on Limestone.
The effect is a scratched, permeable surface with tiny, dirt-attracting holes. At these times, the original finish is taken off by grinding and also then honing.
This technique is referred to as restoraion. We have different Limestone floor restoration products such as; diamonds for honing and also grinding, epoxy fillers, grouts and also polishing compounds to produce a high finish.
Wear over aged Limestone floors is a consequence of years, perhaps centuries, of being walked over. Laminations in the Limestone can break up, tiles may crack, and also the linestone subfloor cound move.
This wear is also a reminder of your building’s historical past, it is therefore often better to accept these imperfections instead of disturb a vintage floor. Most of the time, these older floors are installed in listed buildings and also any work is stringently governed via the Heritage authorities.

Limestone sealing starts by determining the kind of Limestone and also the condition of the floor base.
Sealing Limestone Floors Without A Damp-Proof Membrane
Limestone has been used as since the stone age. Buildings before the 1950s can have stone floors set directly onto compact earth, a chalk base or lime-based mortar.
These floors have to let the passage of moisture through the floor base, which impacts the selection for a floor sealer.
These types of floors are sealed with a penetrating sealer to allow the free movement of moisture through the stone.
Sealing A Polished Limestone Floor
Polished Limestone is typically sealed with a penetrating impregnating sealer. 1 or 2 coats of sealer must be sufficient for polished Limestone. On polished Limestone, the sealer must be re-applied annually. Impregnating sealers on Limestone will not stop acid etching and chemical damage. {This means that acid spills for example [xfield_acid-spills] will penetrate the impregnating sealer on the Limestone floor, leaving a dull etch mark.} If there is a storing dye when you look at the liquid you spill in your Limestone, e.g. dark wine, the etch mark may also be stained with the colour of the spill.
Sealing Honed Limestone Floor Tiles
Limestone tiles with a honed finish will have a matt or sheen surface. Stone is more porous than polished Limestone, but less permeable than tumbled Limestone. If you like a natural matt-look, an impregnating sealer retains the initial finish. Just like polished Limestone, an impregnating sealer does not stop acid etching.
Honed Limestone tiles may have a film-forming or surface sealer. Because name implies, the sealer forms a protective film the area of the tiles. This film provides extra protection against damage from acid etching. The film acts as a wear surface, taking damage from foot traffic as opposed to the tile itself. Since the protective sealer sits the outer lining of the Limestone, we advise using a couple of coats of impregnating sealer first. The impregnating sealer helps protect the stone in areas where the surface film wears away.
A surface sealer lasts for two to 4 years before it requires topping up. We recommend checking wear regions every six months to check on for wear. If a place is showing wear, deep clean areas to clear out any surface soil, then top the areas up using one or two coats of sealer.
Using this system, a sealer can last for a long time, without suffering from an ugly build-up of protective sealer in areas that don’t need it.

How do you clean unsealed limestone?
Scrub the surface with a with a soft-bristled, non-metallic scrub brush ans a ph neutral Limestone cleaner. Rinse the stone with clean water and wipe clean with a microfiber cloth.
What causes black stains on limestone?
Chemicals from air pollution react with the stone to stain the stone. Also lichen develops to make black and white coloured spots.
Will bleach damage limestone?
Bleach should never be used on any limestone surface as it will damage the finish. If you accidentally spill bleach on Limestone, rinse with penty of clean water and dry.

Limestone is more porous than other stone, and usually light in color, so is more easily stained.
