HML 1 / Historical plaster

  • Reinforced with polypropylene fibre
  • Maximum fraction 1mm
  • Does not contain cement
  • Designed for the creation of the upper finishing layer on HML-4 plaster
  • For new and renovated buildings
  • Suitable for restoration and repair of loose and porous plasters
  • Suitable for use on old lime plasters
  • High water vapor permeability
  • Excellent resistance to temperature fluctuations
  • Excellent adhesion to the surface
  • Ecologically clean
  • Easy to process


  • The surface to be renovated must be dry, cleaned of dirt, grease, lichen, paint
  • Alkyd-based coatings must be mechanically removed 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 HML1 is a loose consistency material
  • 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 3 to 12 mm
  • Lime, cement or additives improving the properties of the concrete composition must not be added to the dry mixture
  • Do not use dirty equipment and bags stored in inappropriate conditions or previously opened for the preparation of plaster
  • 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 lime, 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


  • 25 kg / paper bags / 48 bags on a pallet
  • 1,000 kg / Big-Bag packaging / pre-ordered
  • 10,000 kg - 20,000 kg / mobile transport silos
