Removing Cement Staining from Internal and External Stone Paths and Patios
It is essential that you understand which stones can be treated with acidic products in order to remove cement and which cannot. Read the following, call us if there are any queries and make sure you do small test areas. This is YOUR responsibility.
Removing cement staining or residues from ACID RESISTANT STONE OR TILES such as most sandstones, most granite and most slates is relatively easy using Builderase.
You must refer to the Technical Instructions once you have navigated to the Product Pages and do small test areas first. If you encounter any issues with your test area, please Contact Us before continuing.
Removing cement staining or residues from ACID SENSITIVE STONE OR TILES such as marble, limestone, travertine and all cement based materials is difficult. You can try using Powerase and a scrubbing brush or nylon pad. We are usually successful but results can be mixed.
In the case of acid sensitive stone or tiles we suggest you Contact Us for advice first, preferably sending pictures as well. With these types of stone and tiles great care must be taken to avoid cement or grout staining from the outset.
Refer to full product guides on the product pages
