Application is ideally done on visually connected areas in order to achieve homogeneous results.\u003c\/p\u003e\n\u003cp\u003eA one-coat primer coat application may be sufficient. In case of intensive stains two up to three applications are recommended. A drying time of at least 12 hours between the coats is required.\u003c\/p\u003e\n\u003cp\u003eA drying time of 24 hours is necessary prior to subsequent coating with KEIM interior paints. The application is to be done in sections. Stir material well before application. Do not apply on distemper paints. Do not mix with other paints or tinting pastes. Dilution with water will impair the isolating properties.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication\u003cspan\u003e \u003c\/span\u003eConditions\u003c\/strong\u003e\u003cbr\u003eAmbient and substrate temperature above 5°C and below 30°C.
