Preparation & Application
Remove loose material and old coats mechanically or with a water pressure jet. All loose and friable material should be cut back to a sound level.
Having cut the stone back to a sound base, KEIM Restauro Grund, mixed with clean cold water to a moist earth consistency, should be applied to the level of approximately 5mm below the finished surface. Apply to pre-wetted surfaces in one or more layers from 10mm to 50mm maximum. KEIM Restauro Grund is only suitable if the depth is in excess of 10 to 15mm. Finishing Once the base mortar has set, roughen the surface and allow at least one day to elapse before further finishing operations and application of KEIM Restauro Top.
