Limestone Floor Sealer Damaged by Dog Urine in Weybridge
Weybridge is an affluent commuter town with good train connections into London Waterloo, as a result, there are some impressive houses here, many of which feature beautiful polished stone floors. This particular residence in Weybridge had a very large Limestone tiled floor installed in their Kitchen/Dinning Room, the floor had been cleaned and sealed about a year prior, so it was still in good condition however the customers ageing dog had a few accidents which had damaged the sealer.
Urine contains Uric Acid which being an acid can damage the sealer, this is why for daily cleaning we always recommend using pH neutral cleaning product such as Tile Doctor Neutral Tile Cleaner or Stone Soap if the floor is polished. Limestone and Travertine are especially vulnerable to acids due to their high levels of calcium carbonate and often results in pock marks or small holes forming in the stone.
Resealing a Polished Limestone Floor
Once we’d moved the furniture to another room I started with a deep grout clean. I ran a dilution of Tile Doctor Pro-Clean along the grout lines then left it to dwell for five minutes while I got the wet vacuum from the van. When ready I cleaned the grout by hand with a hard nylon brush and then extracted the soiled cleaning solution with the wet vacuum.
With the grout now clean and the soil removed I set up my rotary floor cleaning machine ready to burnish the stone tile and restore the finish with a set of diamond encrusted burnishing pads.
The first pad in the set to be applied is a coarse 400 grit pad that is designed to remove existing sealers and dirt and is run over the tiles with water for lubrication. During the following hours the process was repeated with the medium 800 grit and fine 1500 grit pads which gradually polish the stone and return the shine. The floor is rinsed between each pad to remove the soil which is generated from burnishing.
This process took up much of the day so after rinsing the floor after the 1500 grit pad and extracting the soil with the wet vacuum I left the customer strict instructions not to spill anything on the unsealed floor. The tiles need to be dry before re-applying the sealer and any remaining moisture from the rinsing should evaporate overnight.
Sealing Limestone Tiles
Returning the next day, I tested the floor was dry the applied the first coat of Tile Doctor Ultra-Seal which is a natural look impregnating sealer that soaks into the pores of the stone protecting it from within. Once I’d wiped away any excess I left it to dry for half an hour before applying a second coat.
Breaking for lunch allowed sufficient time for the sealer to dry and I was able to complete the floor with a final polish.
