Removing marks from a limestone fireplace can be a trick job. Often limestone fireplaces are fitting by gas engineers who are fitting the fireplace at the same time. They unlike tiles are not aware of how porous the limestone surround can be. As a result, the wonder surrounds are not sealed and often stain very easily. A tea cup or glass of red wine left of top, then knocked over can be all it takes to have a very unsightly stain on your fireplace.
In this post we are looking at a different type of stain that can also look unsightly in your marble or limestone fireplace. Watermarks, which can be caused by spills or from a leak or a flood in your house can be very tricky to remove. The picture below shows a fireplace effect by a burst pipe, which ended up flooding the floor and walls and causing the water marks in this limestone fireplace.
Once the rooms where completely dried out, very deep water marks, we’re left on both the right and left hand side of the fire. Cleaning alone would not remove these marks unfortunately for this customer.
To remove these marks a specialist paste would need to be made up at the correct concentrate and applied to the fireplace. A specialist none etching cleaning solution is added to a dry powder and mixed till a paste is formed. The paste is then applied to the stains and should be left on over night. Plastic sheeting is applied to stop the pasted drying up and in turn the solution drying up on the stone.
As this fire place was dirty all over, we decided to apply the paste solution to the whole fireplace, rather than just the affect areas. If it was just applied to the affected areas of the limestone fireplace, you can end up with a cleaner patch than the rest. When we returned the following day, the results were great. Once the pasted was cleaned off and neutralised, the fireplace looked as below. At this point the bottom part had not been cleaned completely.
The bottom part of the fireplace was then given a final clean, and was refinished using some diamond abrasive pads. The brass part of the limestone fireplace was then replaced and the finished product was as below.
Once the fireplace was completely dry a solvent based impregnator was applied to prevent any further staining from drinks and food spills. The sealer that was used was Lithofin Stain Stop. Once dried the fireplace was left clean and restored and well protected to help keep it clean for many years to come.
