Özellikler
- High salt storing capacity
- Porosity > 45 vol%
- High sulphate resistance and low active alkali content (SR/NA)
- Enables water vapour diffusion
- Capillary-active
- Single-layer application thickness from 10 to 40 mm
- Machine workable
- Substrate requirements: Clean, dust-free and capable of supporting a load.
- Preparations: Remove render, paint layers and coatings at least 80 cm above the damaged area. Chase out friable joints to a depth of at least 2 cm. Pre-wet absorbent substrates so that they are slightly damp. Substrate: absorbent with low strength Apply SP Prep as a bonding layer in a network pattern (covering 50-70% of the surface) at a layer thickness of max. 5 mm. Alternative: apply SP Levell as a scratch coat (contact layer). Substrate: weakly absorbent Apply SP Prep so that it fully covers the surface (100%) at a layer thickness of max. 5 mm. Alternative: apply SP Levell as a scratch coat (contact layer). Substrate: mineral waterproofing slurry Apply SP Prep over the entire surface area (100%) of the last slurry layer, wet-on-wet, as a bonding layer with a maximum coating thickness of 5 mm.
- One-layer Apply product using a suitable tool or machine. Two-layer Roughen the first layer with a render comb. Apply second layer once sufficiently dry. Level off surface with a long float. Use a render comb to roughen horizontally in preparation for the next layer of render after setting. Alternative: Once the surface is sufficiently dry, use a grated scraper to prepare it for subsequent coatings.
- Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar. Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days. Hairline/shrinkage cracks are safe and are not cause for complaint as they do not impair the properties of the mortar. To ensure that the renovation is successful, the relevant drying conditions according to WTA Code of Practice 2-9-20/D must be met. Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing. When processing in machines, the product-specific data, such as strength, air void content, etc. might change.
- Clean tools with water while the material is still fresh.
- If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.
- Approx. 9.5 kg/m²/cm layer thickness
- Apply to a large enough trial area to determine the precise amount required.
- May contain traces of pyrite (iron sulphide). Do not use on gypsum-based substrates. The mixing water must be of drinking water quality. Low chromate content in accordance with Directive 2003/53/EC. Always set up a trial area/trial areas first. The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity. Current regulations and legal requirements must be taken into account and deviations from these must be agreed separately. The relevant test certificates must be observed when planning and carrying out work.
- Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
