Cleaning Sandstone
Our Sandstone cleaning services deal with a number of Sandstone floor types, covering common local sandstone like York stone and natural flagstone.
To start with Strong Sandstone cleaning chemicals break up the ingrained dirt. And then Our professionals leave the cleaner for around 20 minutes to break down the greasy ingrained soil. Rotary scrubbing machinery removes the soil out of the stone.
Then, we rinse away the dirty water and check the condition of the floor. We repeat the scrubbing until the floor looks clean. Smooth Sandstone is generally clean after 1 or 2 scrubbing and rinsing steps. Tumbled Sandstone usually needs more passes. The impacted soil in deep cavities can not be got rid of with srubbing machinery alone.
Pressure Rinsing Sandstone
The remaining step in cleaning Sandstone tiles, is named hot rinse and extraction.
Having integrated high pressure nozzles, it is possible to clear away persistent dirt.
Any remaining dirt will be taken out with the pressure rinsing.
Sandstone Restoration
After the floor has been cleaned, we can see if there are more problems to be resolved.
Repairing Sandstone Floor Grout
Sandstone floor grout can get marked from spillages and affected extreme chemicals. Deep grout can be cleaned then regrouted with new fresh grout.
In the event that grout isn't more than three mm deep, we use diamond cutters clean out the existing grout before re-grouting.
Removing grout is a pricey process and it is usually restricted to particularly bad areas.
Cracked, chiped and damaged floor tiles can be replaced or repaired. The floor is then left to dry ready for applying a stone sealer.
Sandstone Sealing
Assessing the underlying floor will determine the kind of sealer to use.
Sealing Floors That Do Not Have A Damp-Proof Membrane
Stone floors in older houses were not usually set over a damp-proof membrane Layer. The UK has plenty of these old buildings with stone basement floors. Any sealer will have to enable the free movement of moisture through the Sandstone. In this case, we choose a silane penetrating impregnating sealer. 3 or 4 coats of sealer really should provide the required level of coverage. When too little sealer is used, the sealer will not protect the Sandstone.
Sealing Floors With A Damp Proof Membrane
If you want to maintain the original finish, impregnating sealers will meet your requirements.
Film-forming or surface sealers are also used on Sandstone.
A surface sealer sits over the surface of the stone, supplying spill and abrasion protection.
This film provides added protection against acid-etching.
The film acts as a wear layer, accepting wear from foot traffic in place of the Sandstone itself.
Pre-sealing with an impregnating sealer is advised to improve the protection.
When the surface sealer starts to wear, the impregnating sealer still offers protection up until the floor is re-sealed.
Surface sealers normally keep going for 2 to 4 years.
If at all possible, inspect wear every six months.
Deep clean wear areas for them to be re-sealed.
Top the location up with a couple of coats of sealer.
After this method, a sealer can work for for decades and years.
