CERESIT CL 50 consists of 2 components: powder (2 x 3,75kg bags) and a liquid component (5l bucket). First pour the liquid into another bucket, then add the powder in the right mixing ratio and stir with a slow-rotating stirrer until the mixture is completely free of lumps. After a maturing time of 5 minutes, give the mixture another stir so that a spreadable consistency is achieved.
It is necessary to apply two sealing coats with a dry layer thickness of at least 2 mm. The first coat should be applied with a brush. The second coat should be applied crosswise to the first one. The thickness of a single layer of CERESIT CL 50 should not exceed 1mm.
Can be applied on concrete plasters and cement screeds, cement and lime plasters, aerated concrete, calcium sulphate, gypsum substrates, plasters and plasterboards. Do not use CERESIT CL 50 outside on old ceramics, mastic asphalts and paintwork.
