KEIM Block Prime formerly Blockweiss Stain Blocker

KEIM Block Prime is a white pigmented water based priming coat with highly isolating properties, used to primer interior surfaces which have a staining / bleeding tendency.

Best Uses

KEIM Block Prime is used to prime interior surfaces which have a staining/bleeding tendency. Keim Block Prime is best suited used to isolate and block the bleeding of marks and stains from e.g. water, oil, tar, soot, smoke or coloured pen. The substrate must be sound, dry and clean before application.

• Highly isolating
• Low-odour
• Aqueous
• Pigmented, very good hiding power

Application

KEIM Block Prime is applied to interior surfaces with problematic stains and bleeding. Application is ideally done on visually connected areas in order to achieve homogeneous results. A 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. A thorough drying 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.

Keim Block Prime is part of the extensive range of Keim products available from Promain.
