Advice
Before using the preparer, it is recommended to test the substrate's porosity to ensure compatibility with this treatment. For very dense surfaces, consider alternative solutions if porosity enhancement is not achievable. If using the product as a cleaner, make sure to rinse the surface thoroughly after application.
