A Stontex cleaning product called “Cement & Grout Residue Remover” will remove efflorescence / lime stains from most materials except limestone, marble or travertine which are acid sensitive.
The Stone Doctor recommends that all natural stone, concrete and brick should be sealed once the material is clean and dry.
You have two choices:
- Our “Stontex Platinum Stone Sealer” which lasts up to 5 years before you need to re-seal or
- For a permanent solution we recommend our premium sealer “Dry Treat Stain Proof”.
To work out how much sealer you will need please see our Coverage Rates.
