BUDOGRUNT ZG – Universal primer recommended for acrylic facade paints
A universal product based on water-dilutable acrylic dispersions, intended for proper preparation of the substrate before application of paint coatings, mineral renders and ceramic claddings. It is used for priming all typical absorbent construction substrates present outside buildings, including in the KABE THERM RENO* EWI system. It is especially recommended for substrate priming before applying BUGOFLEX and AKRYLATEX acrylic façade paints, as well as MARMURIT, MARMURIT COLORATO and MOZAIKER AKORD, MOZAIKER AKORD COLORATO mosaic renders. To be applied on mineral substrates (such as concrete, aerated concrete, cement render and cement-lime render). Note: The product should not be used for priming substrates with low wettability (such as dispersion paint coatings and plastic-based renders).

• Improves paint coating adhesion
• Reduces and equalises substrate water absorption
• Excellent penetrating properties
• Strengthens the substrate surface
• Reduces dustiness
SUBSTRATE PREPARATION: Substrate should be sound/stable (without scratches and cracks), degreased, clean and dry, and free of biological contamination and chemical efflorescence. In case of algae/fungi growth, the substrate should be cleaned mechanically and then washed with water and disinfected with ALGIZID. Any loose layers, not bound to the substrate (e.g., loose render or flaked coatings), should be removed. Old and/or dirty substrates should be washed and degreased with water and CLEANFORCE cleaning agent. For particularly uneven substrates (from 5 mm to 15 mm), first use levelling compounds, and then smooth out the whole surface with KOMBI FINISZ or KOMBI HYDRO STOP base coat. Minor unevenness (up to 5 mm) can be levelled out and smoothed straight away with KOMBI FINISZ or KOMBI HYDRO STOP base coat. An absorbent substrate should be primed with BUDOGRUNT ZG before applying levelling compounds or base coats. If the product is applied on new mineral substrates (i.e. concrete, cement render and cement-lime render) – a minimum 2-week curing period is required.
PRODUCT PREPARATION: The packaging contains a ready-to-use product. It cannot be diluted.
APPLICATION: The product should be applied on the substrate in one or two layers (depending on the substrate water absorbency) with a brush, roller or by spraying, using the “wet on wet” method. Use mechanical spraying only in windless weather. Note: The applied product should completely penetrate the substrate, but, at the same time, should not create a tight coating on its surface (fi lm) or stains.
DRYING: The curing period of the product applied to the substrate before applying the paint is about 24 hours. Protect the fresh coating against precipitation and condensation until it dries completely.
USEFUL HINTS: Product application and drying should take place on dry days at temperatures over +5°C. Tools should be cleaned with water immediately after completing work. Avoid applying the product on surfaces directly exposed to sunlight or during strong wind.
