NOVALIT GF
Priming and impregnating product under polysilicate facade paints
High quality product based on small-particle acrylic dispersion with an addition of silicone hydrophobising agents. Intended for the proper preparation of the substrate under NOVALIT F, NOVALIT PLAN and NOVALIT L polysilicate facade paints, as well as hydrophobic impregnation of all typical, absorbent construction substrates outside buildings. To be applied for priming of mineral substrates (such as concrete, traditional lime renders, cement-lime renders and cement renders as well as thin coat mineral renders, silicate renders, polysilicate renders) and on substrates covered with well set and bound polymer-based coatings. It is specially recommended for the impregnation of absorbable and weathered concrete substrates, cement screeds, cement renders, cement-lime renders and lime renders, cement and fibre boards and raw surfaces made of bricks, blocks, concrete blocks and other ceramic or silicate materials of that type.

– Improves coating adhesion
– Reduces and equalises substrate water absorbency
– Assures high vapour permeability
– Protects from stains and efflorescences
– Reduces dustiness
– Does not change the substrate colour
– Features a very high adhesion to both mineral substrates and
those covered with coating or mortar based on polymer
SUBSTRATE PREPARATION: Apply to a sound/stable and clean substrate (without cracks and delaminations), degreased, dry, and free of biological contamination or chemical efflorescence. In case of algae/fungi growth, the substrate
should be cleaned mechanically and then wash with water and disinfect with ALGIZID. Any loose layers not bound to the substrate (i.e. loose render or flaked coatings) should be removed. Old and/or dirty substrates should be washed off and degreased with water and CLEANFORCE cleaning agent. For uneven substrates, first use levelling compound and then level the surface with KOMBI FINISZ levelling/finish render. Small unevenness can be levelled out at once with KOMBI FINISZ levelling/finish render. Absorbent substrates should be primed before finish levelling and smoothing compound and/or levelling compound is applied. If the product is applied on new mineral substrates (such as concrete, lime render, cement-lime render and cement render), 2-week curing period is required.
PRODUCT PREPARATION: The packaging contains a ready-to-use product. It cannot be diluted.
APPLICATION: The product to be applied on the substrate with the use of a paint brush, roller or spraying. Very absorbent substrates should be impregnated twice by means of a ‘wet on wet’ method.
DRYING: Before applying paint, the product used on the substrate requires curing of ca. 12 hours. Protect the newly made coating against precipitation and condensation until it dries completely. Note: Full hydrophobic properties are
achieved after 7 days.
USEFUL HINTS: To be applied on dry days with temperatures above +5°C. Drying time may be longer due to low temperatures and high relative humidity. If such is the case, it is necessary to wait until the primer dries out completely
before applying the paint. All tools should be cleaned with water after work is completed. Application during direct exposure to sunlight or in strong winds is not recommended. To protect wet product against inclement weather conditions, scaffolding should be covered with some protective netting.
