STANDARD RECOMMENDATIONS

All loose, flaking and unstable material must be identified and thoroughly removed using stiff brushes and broad-bladed scrapers to get back to a sound edge; edges should then be feathered in. Ensure that any materials left remaining and the underlying substrate is sound and adhering well.
Surfaces should be repaired/re-rendered using appropriate materials and dressed back to the surrounding substrate.
Any newly repaired areas must be allowed to dry out for a minimum period of 15 days (28 days for NHL (Natural Hydraulic Lime) prior to the application of KEIM Mineral Paints.
Use only KEIM recommended fillers and sealers. Acrylic, resin and gypsum based fillers particularly are not recommended for use with mineral paints.
