Preparation

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
• Apply SP Prep or SP Prep rapid as a bonding layer in net form (covering area 50-70%) with max. 5 mm layer thickness.
• Alternative: apply SP Top White as a scratch coat (contact layer).
• Substrate: weakly absorbent
• Apply SP Prep or SP Prep rapid at full coverage (100%) with max. 5 mm layer thickness.
• Alternative: apply SP Top White as a scratch coat (contact layer).
• Substrate: mineral waterproofing slurry
• Apply SP Prep as a full-coverage bonding layer on the last slurry layer wet-on-wet.

Application

• Contact layer
• Apply the product using a suitable tool.
• 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.
• Alternatively, apply the total layer thickness in 2 coats, wet on wet, embedding reinforcement fabric (Tex 6.5/100).
• Ensure that fabric sheets overlap by at least 10 cm.
• Level off surface with a long float.
• Finish the surface once set.
• Prepare the surface for subsequent layers with a grated scraper after sufficient setting.
• Pre-wet hydrophobic surfaces with detensioned water so that they are slightly damp before applying further render coats.

Application instructions

• Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.
• On critical substrates (highly uneven, fissured, mixed masonry) we recommend incorporating the reinforcement fabric in the upper third of the restoration render.
• Apply additional diagonal reinforcement to the edges of building openings.
• Protect wet mortar surfaces against frost, rain and drying out too quickly for at least 4 days.
• At larger coating thicknesses of 10 - 30 mm, it is recommended to apply the mortar "wet on wet" in the render layer.
• Work can continue on scraped surfaces can after 24-48 hours.
• Work can continue on smoothed surfaces after min. 14 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.

Working tools / cleaning

• Mixing tool, trowel, smoothing trowel, aluminium float, render comb, sponge float
• Clean tools with water while the material is still fresh.

Storage / shelf life

• If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.

Usage

• Approx. 8.8 kg/m²/cm layer thickness
• Apply to a large enough trial area to determine the precise amount required.
