Primers

Product based on potassium water glass intended for strengthening all mineral construction substrates outside and inside of buildings and for proper preparation of the substrate under CALSILIT F silicate facade paint and HISTORICA FKZ. It is used for surface reinforcement of absorbable and weathered concrete substrates, cement screeds, lime renders, cement-lime renders and cement renders, cement and fibre boards and raw surfaces made of bricks, blocks, hollow blocks and other ceramic or silicate materials of that type. To be applied for priming only mineral substrates (such as concrete, traditional lime renders, cement-lime renders and cement renders as well as thin coat mineral and silicate renders).
Note: Do not apply on substrates covered with paint coatings or top coats based on polymers or on gypsum substrates.

– Mineral character
– Improves coating adhesion
– Reduces and equalises substrate water absorbency
– Assures high vapour permeability
– Binds and strengthens the substrate
– Has high good penetrating properties
– Reduces dustiness
– Does not change the substrate colour
