PERMURO ROLL RENDER; Acrylic render to be applied with a roller

To be used as manually applied thin-coat renders with a roller, outside and inside buildings. 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. It allows you to create a layer that masks minor scratches and minor surface irregularities. The substrate should be primed with PERMURO GT before applying the render.

• Resistant to adverse weather conditions
• High impact resistance
• Eff ective masking of minor scratches and substrate irregularities
• Very good adhesion to substrate
• Anti-fungal and algae protection (reduces the growth of algae and fungi)
• Wide range of colours
• Easy to apply and create patterns

SUBSTRATE PREPARATION: Substrate should be sound/stable (without scratches and cracks), degreased, even and dry, as well as free of biological contamination and chemical effl orescence. 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 fl aked 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), use fi lling 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 / BUDOGRUNT WG before applying levelling compounds or base coats. Fresh concrete substrates, cement and cement-lime renders can only be plastered after min. a 4-week curing period, gypsum renders after 2 weeks, while drywall systems directly 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 fi tted 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 16 kg of the product). Quantity of added water may vary depending on the substrate type, drying conditions and application method.
APPLICATION: Render may be applied on the substrate by means of a roller with various types of tips made of wire, sponge or bristle (depending on the assumed decorative eff ect). Apply one or two layers, as necessary.
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. The newly applied render should be protected against precipitation and condensation until it is fully hardened. After applying render, closed rooms should be ventilated until the specific smell disappears.
USEFUL HINTS: The fi nal eff ect may depend on the substrate type. Therefore, for heterogeneous substrates, it is recommended to fi rst smooth out the entire surface with KOMBI adhesive/base coat. In order to avoid colour diff erences, 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. The render should be applied and dried on dry days at air temperatures from +5°C to +25°C. Avoid applying in direct sunlight or during strong winds. In order to protect the undried render against severe weather conditions, it is recommended to use appropriate protective meshes or tarpaulins on scaffolds.
