STONEDOCTORS QUESTION OF THE MONTH – REMOVING WHITE STAINS FROM STONE
ADVICE ON HOW TO REMOVE ”WHITE STAINS” FROM THE STONE
Here is our pick for July:
I have granite stone on my house. Some of the stones have gone white. It looks like the whiteness is “weeping” from the stone joints maybe caused by lime in the cement mix. Have you seen this before?
- Is it possible to clean this off the surface of the stone and also remove the whiteness from the stone joints? - Also do you recommend sealing the stone, is this a service you do?
Yes this is a common problem our Stontex Cement Away is very effective at removing these efflorescence / lime staining issues. We recommend you do a small sample area first apply cleaner on surface for about 5mins during this time agitate with a nylon brush then wash off. Once the stone is clean and dry the recommended sealer would be our premium Dry Treat Stain Proof coverage for granite is 15sqm per quart. If you wish we can recommend registered contractors that can carry out the cleaning and sealing for you (just let us know where are you based and we will send you details of a specialist in your area).
