To be used as manually or machine applied (sprayed) thin-coat renders in interiors. Intended for use on mineral substrates (e.g., concrete, cement render, cement-lime render) and on substrates covered with a well-bonded plastic-based paint coating. The substrate should be primed with PERMURO GT before applying the render.

• Wide range of colours
• Can be machine applied (sprayed)

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 fungi growth the substrate should be cleaned mechanically and then washed with water and disinfected with fungicidal agent for interiors. Old mineral substrates should be washed away with a dispersed stream of water. Any loose layers, not bound to the substrate (e.g., loose render or flaked coatings), should be removed. 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 WG before applying levelling compounds or base coats. If the acrylic render is applied on new mineral substrates (e.g., concrete, cement render, cement-lime render) – a minimum 4 weeks of curing are required, for gypsum renders a minimum of 2 weeks, while drywall systems can be directly coated after grinding and dedusting.
PRIMING: The substrate should be primed with PERMURO GT before applying the render. The curing period of the product applied to the substrate before applying the render is about 24 hours. To reduce the risk of the substrate colour showing through the top coat, it is recommended to use a primer with the same colour as the render.
PRODUCT PREPARATION: The packaging contains a ready-to-use product. If stored for a long time and directly before application, the product should be thoroughly mixed (with a low-speed mixer fitted with a basket stirrer), until a smooth, homogeneous consistency is obtained. Further mixing is not recommended, as it may result in excessive aeration of the product. If required, add a small amount of drinking water (max. 0.25 l per 25 kg of the product). Quantity of added water may vary depending on the substrate type, drying conditions and application method.
APPLICATION: Using a stainless steel trowel, apply a thin, uniform layer of the product to the substrate. Then, use a plastic trowel to create a texture, rubbing the applied compound with circular motions (solid texture). Machine spraying using a sprayer with a working pressure of 3-4 atmospheres and a nozzle diameter of 6 mm. While spraying, the gun should be held perpendicularly to the substrate at a distance of 0.4-0.6 m.
DRYING: Typical drying time of the render applied to the substrate is approx. 6 h (at +20°C, 55% RH). Complete hardening of render after approx. 48 hours. Note: Drying time may be longer, up to several days, due to low temperatures and high relative humidity. After plastering, closed rooms should be ventilated until the specifi c smell disappears.
USEFUL HINTS: The final effect may depend on the substrate type. Therefore, for heterogeneous substrates, it is recommended to first smooth out the entire surface with KOMBI adhesive/base coat. In order to avoid colour differences, it is necessary to create a surface constituting a separate architectural whole in one work cycle with material from the same production batch, using the “wet on wet” method. Tools should be cleaned with water immediately after work is completed. Avoid working in draught and high humidity.
