Processing

  • The surface to be renovated must be dry, cleaned of dirt, grease, lichen, paint
  • Alkyd-based coatings must be mechanically separated from the entire surface
  • Gaps and brickwork seams must be carefully cleaned of atmospheric dirt
  • Loose parts should be separated to the hard layer of the surface
  • Cracked and loose materials are recommended to be separated mechanically or with a high-pressure washer
  • The layer of old plaster damaged by salts should be cleaned 1m above the upper line of salinization
  • Treat the old plaster with SAKRET TGW primer
  • SAKRET HM 10 is a material with a loose consistency
  • The mortar can be prepared with a mixer, a concrete mixer or the mortar preparation and development technique offered by SAKRET SERVISS
  • The mortar is stirred for 3 - 5 minutes until it acquires a homogeneous consistency
  • Layer thickness: from 5 to 20 mm (thickness of one layer 5-12 mm)
  • Lime, cement or additives improving the properties of the concrete composition must not be added to the dry mixture
  • Dirty equipment and bags stored in inappropriate conditions or previously opened should not be used for plaster preparation
  • The technical data refers to a temperature of +20°C and 50% relative air humidity. Lower temperature increases, higher - decreases the specified values
  • During the hardening phase of the mortar, protect from the sun, drafts and excessively high temperatures (>30°C)
  • Protect fresh adhesive from rain and too rapid drying
  • When the mortar has started to bind, no more water can be added!
  • Wash containers and tools with water immediately after processing the mortar
  • Hardened mortar can only be removed mechanically
  • Contains cement, reacts alkaline
  • Protect skin and eyes, follow technical instructions. If the mortar gets into the eyes, rinse with a large amount of water, if necessary, consult a doctor
  • Protect the packaging from weather conditions, store on wooden pallets, in a cool and dry place, cover torn packaging immediately
