Substrate requirements

  • Clean, dust-free and capable of supporting a load.


  • 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 temperature: min. 5 °C max. 30 °C
Mortar cover / Filling knife / Trowel application / Application by spraying
  • 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.
