Cleaning Sandstone
Our Sandstone cleaning programs covers a number of Sandstone floor types, among them traditional local sandstone like York stone and flagstone.
To start with,Our professionals apply a strong Sandstone floor cleaner and degreaser on the floor. And then we leave the cleaning solution for about 20 minutes to break up the greasy ingrained soil. Our professionals use a commercial scrubbing machine to work the cleaning solution deep to the Sandstone.
Remove the slurry using a clean water rinse. Continue scrubbing plus rinsing until the floor is clean. Honed Sandstone is normally clean after a couple of scrub and rinse steps. Tumbled Sandstone needs more passes. Srubbing machinery might not get rid of all soil.
Pressure Rinsing Sandstone
A hot pressure rinse step is often necessary.
The state-of-the-art combination of high-pressure and whirling nozzles frees difficult soil that is immediatelly vacuumed away.
The Sandstone floor has become nice and clean.
Sandstone Restoration
After removing the soil, the floor may need further sandstone restoration.
Repairing Grout on a Sandstone Floor
Grout will get stained from spillages and affected extreme cleaning chemicals. Deep grout can be deep cleaned then over-grouted with new grout.
If the grout is not more than 3 mm deep, we have diamond cutting tools to remove the existing grout before re-grouting.
Costs can increase if grout has got to be taken out and the area regrouted.
Cracked, damaged and chipped tiles can be replaced or repaired. The floor is then left to dry overnight ready for applying the stone sealer.
Sandstone Sealing
Before sealing the floor, the condition of the installation must be assessed.
Sealing Sandstone Floors That Have No Damp Membrane Layer.
Old homes in plenty of cases don't come with a damp proof film. The United Kingdom has a considerable amount of these older properties with stone ground floors. Any sealer should allow the movement of moisture through the Sandstone. types of floors need to have a penetrating impregnating sealer. 3 or 4 layers of sealer really should give the necessary amount of protection. 1 layer of impregnating sealer is not enough to protect these floors.
Sealing Sandstone Installed On A Floor With A Damp Proof Membrane Layer
Impregnating sealers will preserve the original appearance.
Film-forming or surface sealers are put on on Sandstone.
A surface sealer stays on the top of the stone, offering spill and abrasion protection.
Surface sealers give more protection against acid etching.
Surface sealers render extra protection for the Sandstone and the grout.
Pre-sealing using an impregnating sealer is recommended to improve the protection.
The impregnating sealer helps protect wear areas.
A surface sealer will have to be topped-up after two to 4 years.
We advise evaluating wear areas every 6 months for traffic.
Areas displaying wear should be deep cleaned.
Top the location up with a couple of coats of sealer.
Following this method, a sealer can continue working for decades and years.
