Important Considerations:

Before application, it is crucial to ensure that the surface is thoroughly cleaned with HMK® R155 Intensive Cleaner and allowed to dry. The surface must be chemically clean and dry prior to application to maximize the effectiveness of the impregnator. Testing the product on a small, inconspicuous area before full application is recommended to ensure compatibility and performance.

For ongoing maintenance, HMK® P324 Liquid Stone Soap is recommended to maintain the integrity and appearance of the sealed surfaces.

Note: HMK® S731 should not be applied to rubber, plastics, varnished surfaces, or any surfaces that are solvent intolerant. Regular post-application care includes protecting the treated area from rain and humidity for at least three days.
