Important: Do not wet surface before being treated. HMK® R777 can darken the stone if allowed to dry on the surface, although this may be reversed over time.

Instructions: Protect all adjacent surfaces. If under-floor heating exists, switch it off and allow the surface to cool to room temperature. Apply undiluted HMK® R777 generously and evenly and work into the surface using a scrubbing brush, stiff brush or a suitable pad. Always apply to the whole surface. Place towels soaked with R777 onto the surface to keep the surface wet and to ensure that the treatment does not dry out. Immediately after application, cover the surface with plastic and let sit for 12 hours. Remove any remaining product on the surface after 12 hours and clean the area thoroughly using HMK® R155 Intensive Cleaner -acid free- diluted with clean water about 1:10 and remove the dirty liquid. Afterwards, rinse the area thoroughly with clean water.

Note: Using R777 on soft stones (marble, limestone, etc.) will damage the surface and/or the polished finish. During the 12 hour treatment period, it may be necessary to apply another coat of HMK® R777. In the case of very heavy rust stains repeat the procedure. When using a wet vacuum we recommend that you add HMK® Z102 de-foamer to the water to regulate the amount of foam.

Coverage: About 50 to 160 square feet per liter

Packaging: 1 -  1Liter bottle

Instructions: If under floor heating exists, switch it off and allow the surface to cool to room temperature. Apply HMK® R155 diluted with water (1:2 to 1:10) depending on the intensity of the dirt. Use a scrubbing brush, stiff hand brush or a suitable pad to work HMK® R155 into the surface. Leave for about 10 minutes but do not allow todry (if needed sprinkle a little water to keep the area wet). Scrub the area again and remove the dirty liquid. Afterwards, flood rinse the area thoroughly with clean water. Repeat the procedure as necessary. For stubborn stains, HMK® R155 can be used undiluted. For periodic refreshing of surfaces and to remove protective films use HMK® R155 diluted about 1:20 with water. When using a wet vacuum we recommend that you add HMK® Z702 defoamer to the water to regulate the amount of foam.
