Pre-mixed, quick-setting and drying mortar for bonded or floating screeds. Can be walked on after 4 hours, 8 hours for ceramic laying, 2 days for parquet laying.

it is used for

  • Floating screed
  • Bonded screed
  • Unbonded screed
  • Floating screed with underfloor heating


Screeds manufactured with SEYPRONTO are classified as CT-C45-F6-A 1fl according to UNI EN 13813.

When processed at a temperature of +23 °C, it gives the screeds particular characteristics: rapid hardening without undergoing appreciable shrinkage, rapid drying of the mixing water and residual humidity, high initial and final mechanical strengths that are much higher than those obtained with traditional screeds. SEYPRONTO screeds must be separated from pillars and perimeter walls using, for example, expanded polystyrene or cork. Suitable for building screeds over heating systems. When SEYPRONTO screeds are crossed by pipes that significantly reduce their thickness, it is essential to reinforce the areas concerned with a light hexagonal wire mesh to avoid dangerous weakening of the screed. Very large surfaces must be interrupted with suitable fractioning joints. Any existing joints on the substrate must always be placed on the SEYPRONTO screed.

After 4 hours the screed can be walked on; after 8 hours it is possible to lay the ceramic; after 1 day natural stones; after 2 days the humidity does not exceed 2% in weight and it is therefore possible to lay wooden floors.

The residual moisture of the screed in SEYPRONTO must be measured with a carbide hygrometer, which provides reliable moisture data by weight.

important warnings

  • Strictly follow the indicated water dosage.
  • Do not add aggregates or binders (lime, cement, plaster, etc.) to the product.
  • Do not add any additives (setting accelerators, thinners, etc.) to the product.
  • Separate the screed from the pillars and walls using a compressible material.
  • Cut the screed at the thresholds.
  • Do not apply SEYPRONTO on substrates subject to rising damp or pushing dampness without interlaying a water vapour barrier.
  • Do not apply SEYPRONTO where there is a beating sun, strong wind, temperatures below +5°C and above +35°C.
  • If ceramic tiles are to be laid on the product, please refer to UNI 11493, paragraph 5.2 in particular.
