Remove all loose and flaking material, treat ferrous metal (steel etc.) with a rust inhibiting primer. Let very damp surfaces partially dry out. Ventilate rooms well to allow drying of the surfaces. Treat the entire wall. Apply two cross coats by brush or roller. Apply the first coat thinned 5% with clean water to satisfy the porosity of bare substrates. Allow to dry. Apply the second coat undiluted.

Minimum overcoating interval 24 hours at temperature of 20°C and good drying conditions. Theoretical coverage 3 square meters per litre/per coat. Do not apply if temperatures are below 10°C, especially in areas of low ventilation.
