Cleaning natural flagstone is a question that haunted my client in Felton, Morpeth, Northumberland, for a couple of years.

The homeowner tried a number of different sandstone floor cleaners, including pressure washing, but the stone flooring would not stay clean.

This Indian sandstone floor at a cottage in the small village of Felton was laid by Northumberland stone contractors. They continued the patio stone into the dining room to create a seamless surface.

This is no surprise as this domestic floor is made of Indian sandstone pavers, normally used for outdoor patios.

  • The paving has a rough, abrasive surface
  • Many slabs have an uneven finish
  • The tiles were not sealed
  • The floor had porous jointing compound

Finally, the homeowner searched for cleaning companies offering sandstone floor cleaning Northumberland and found our website.

Preparing The Room For Cleaning

The room had unpainted walls and furniture because the homeowner prefers a natural look. To prevent cleaning solution splashing and marking the walls I installed plastic protection around the walls and internal furniture. The protection has strong adhesive edging, so I first applied low-tack masking tape and stuck the protective sheeting tape to the low-tack tape. Finally, I applied duck tape to the floor edges to give some protection against the scrubbing brushes and pads.

Deep Cleaning The Sandstone Pavers

I started the deep cleaning by applying a solution of alkaline heavy-duty cleaner to a manageable section of the floor. The cleaner was left for 20 minutes to soak into the tiles and dislodge the soil.

During this time, I kept the area wet with cleaner because it is important not to let it dry.
Next, I scrubbed the floor with a specialist soft cleaning brush and a green scrubbing pad.

The cleaning brush was used to remove soil from the undulations and clefts in the tiles and the grout. The scrubbing pad was used to dislodge the soil from the smooth areas of the pavers.
After scrubbing, I removed the slurry with a powerful wet vacuum.
I rinsed the area a couple of times with clean water to remove all cleaning residues.
Areas of remaining soil were cleaned and rinsed until the whole area was clean.
Then I moved onto the next area.

How Do You Remove Stains From Sandstone?

Most stains in sandstone will be removed using a strong alkali cleaner. So the tile floor cleaning removed the majority of stains on the floor. There were a couple of grease stains that had soaked deep into the tiles. I treated these stains with specialist solvent stain removers.

Unfortunately, the solvent stain removers had little effect as the stains had soaked deep into the tiles. I could have tried using a poultice, but there was not enough time for this.

Drying The Floor

I left the floor overnight to dry. To help the floor dry, I installed an air mover and left it running overnight.

Sealing Sandstone Pavers

I started sealing the sandstone with a high quality water-based impregnating sandstone sealer. The impregnating sealer soaks deep into the stone and provides an ideal primer coat for the topical sealer.

I left the impregnating sealer to dry. Then I tested the sealer with a water drop test to make sure there was sufficient sealer in the stone.

In normal traffic conditions, a well-maintained topical sealer will last for two to four years.

The life of the sealer can be extended by applying one or two coats of sealer to any areas showing wear.

This will significantly increase the lifespan of the sealer.

The topical sandstone sealer gives the sandstone pavers a much smoother finish and makes them much easier to mop, rather than having to pressure wash the floor.

I applied 5 coats of topical sealer.

After applying each coat of sealer, I left the floor to dry for around 45 minutes.

I applied a satin finish topical sandstone sealer by hand using a microfiber cloth. I find this method of application the best. I can control the amount of sealer used. I can also make sure the full surface of the tiles are cleaned.

Sandstone Maintenance Advice

Topical sealers are easily damaged by strong floor cleaners. So it is important to clean the floor with the right cleaner; otherwise you will be paying for additional floor restoration services.
I supplied the homeowner with some cleaner recommended by the manufacturer. The cleaner includes a small amount of sealer. So every time they mop the floor, they are topping up the sealer. 
Before mopping, the floor should be vacuumed to remove any dry soil.
 As I noted above, it pays to look after your sandstone floor.

Should You Use A Pressure Washer To Clean An Indoor Sandstone Floor?

My client tried different floor cleaning systems. She couldn’t find a mop that worked. She could only clean the floor with a pressure washer. Pressure washing indoors is very difficult. It needed 2 people to pressure wash the floor. One person to pressure wash and one person to vacuum the water. They worked in small sections to stop water from going everywhere. They had to place blankets around the room’s edges to soak up excess floor cleaners. Pressure washing got the paving clean, but it was removing the jointing compound and the sandstone did not stay clean very long.

Why Does Internal Sandstone Get Dirty?

Natural sandstone is made from fine particles of silica sand particles bound together. The individual grains of sand have sharp edges. The surface of the stone is rough and abrasive, just like sandpaper. The sharp edges of the sand grains scrape soils off footwear and most objects dragged across the floor. Mopping is difficult because a mop sticks to the surface of the stone, making mopping difficult. The surface also traps mopping slurry. The slurry dries into a dirty film.

Is There A Way To Make Sandstone Easier To Clean?
