Removing Stains from a Recently Installed Limestone Fireplace in Jesmond
A homeowner from Jesmond in Newcastle had a newly installed Limestone Fireplace which had become badly stained by the installers during installation. They had attempted to clean the dust off but made rather a mess of it leaving brown staining all over the contemporary limestone hearth, there was also glue staining where the stone sections had been glued together and the glue had been allowed to run off marking the stone and then wiped off.

I asked for some photos of the staining to be emailed over and explained that I was confident the staining could be removed and the fireplace returned to its original condition. As expected, the photos indicated the problem, and I was able to provide a quote without making a site visit. The client was happy with my proposal and quotation, and we booked in a date for the work to be carried out.

Cleaning a Limestone Fireplace
I first protected the surrounding areas, wallpaper, carpet and skirting boards, gave the hearth a light vacuum and set up to carry out the work.
My first cleaning task was to spray the stained areas with a Tile Doctor product called Reduxa. This was left to soak in before using a heat gun set at 400 degrees to gently heat up the treated area. This causes the stain to evaporate out with the Reduxa and may need to be repeated several times until the stain had gone completely. There were several areas that need treating like this so the process was repeated on all the stains.

Next there were several areas of glue staining which needed deep cleaning which was removed using handheld diamond blocks of different grits and a little water.
Sealing a Limestone Tiled Fireplace
Once I was happy the limestone was clean, dry and free of all staining it was sealed with a coat of Tile Doctor Ultra-Seal which is an invisible impregnator that will protect the limestone from spills. Impregnators soak into the stone occupying the pores so that dirt etc cannot reside there, this ensures it stays on the surface where it can be easily cleaned away.

I then tidied leaving the area clean and tidy and the fireplace looking the way it should have done following installation. I then showed the client and he was over the moon that the stains were gone.

On the topic of aftercare cleaning, I recommended using of Neutral Tile Cleaner decanted into a spray bottle with water. This can then be sprayed on and wiped off, being of neutral ph it wonāt impact the sealer which should last for many years.
