PERMURO GT – Primer for acrylic renders

A coloured product based on acrylic dispersion and mineral fillers intended for the proper preparation of substrates for PERMURO acrylic renders (i.e. for PERMURO, PERMURO AVANT, PERMURO AKORD, PERMURO ROLL RENDER and
PERMURO W). For priming of all typical construction substrates outside and inside buildings, including reinforcing layer in KABE THERM RENO, KABE THERM AVANT EWI systems. Intended for use both on mineral substrates (e.g., concrete, cement, cement-lime render), as well as on substrates covered with a well-bonded plastic-based paint coating. On new mineral substrates, a 2-week curing period is required before applying the product.

• Improves the render coat adhesion
• Reduces and equalises substrate water absorption
• Reduces the eff ect of substrate showing if it
is coloured to the render colour
• Facilitates render application and texture modelling
• Features a very good adhesion to both mineral
substrates and plastic-based paint coatings
• Reduces the possibility of algae and fungi growth

SUBSTRATE PREPARATION: Substrate should be sound/stable (without scratches and cracks), degreased, even and dry, as well as 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 level out the wall surface with KOMBI adhesive/base coat. Minor unevenness (up to 5 mm) can be levelled out and smoothed straight away with KOMBI adhesive/base coat. An absorbent substrate should be primed with BUDOGRUNT ZG (outdoors) / BUDOGRUNT WG (indoors) 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. Before using the product in KABE THERM RENO and KABE THERM AKORD, KABE THERM ELASTO, KABE THERM AVANT EWI systems, all base coats should be applied in accordance with the requirements for external thermal insulation composite system (ETICS). Before applying the product, the reinforcing layer has to be fully dried. This can take 3-4 days in typical weather conditions.
PRODUCT PREPARATION: The packaging contains a ready-to-use product. It cannot be diluted.
APPLICATION: The product should be applied on the substrate with a paint brush or roller.
DRYING: The curing period of the product applied to the substrate before applying the render is about 24 hours. Protect the freshly applied coat against precipitation and condensation until it dries completely. Closed rooms should be ventilated after priming.
USEFUL HINTS: During the application and drying of the product, rainless weather should prevail, with an air temperature above +5°C. Drying time may be longer due to low temperatures and high relative humidity. If this is the case, it is necessary to wait until the primer dries out completely before applying the render. Tools should be cleaned with water immediately after work is completed. Avoid applying the product on surfaces directly exposed to sunlight or during strong wind. In order to protect the undried product layer against severe weather conditions, it is recommended to use appropriate protective meshes on scaffolds.
