SikaScreed -1 is a 1-component, ready-to-mix fast-maturing floor laying mortar that matures without shrinkage

It is suitable for indoor and outdoor applications

Advantages

Ready to use, ideal for situations where it is not possible to manage raw materials (cement, sand, water supply), such as confined spaces, historic city centers, etc.

Matures without shrinkage

Very good finish

Fast ripening

Features

Composition Hydraulic binders, quartz/silicate aggregates, copolymers of organic origin and special additives

Compressive strength 7 days ~13 MPa 28 days ≥ 25 MPa

Tensile bending strength 28 days ≥ 5 MPa

Application

  • Mixing: SikaScreed -1 is ready to use
  • Add water for mixing
  • Mixing can take place in a regular concrete mixer, in a Turbosol screw mixer or in a continuous mixing mixer of PFT or Continental type
  • The amount of water to be added must be dosed with the aim of obtaining a plastic, working mixture
  • Too little water (wet consistency) will significantly reduce the mechanical strength of the finished mortar
  • On the other hand, too much water (fluid mixture) will increase shrinkage (drying contraction), so that tiles cannot be laid after 24 hours of application
  • Mixing should be completed within 2 minutes
  • Do not allow the mixer to rotate containing mixed material
  • Use: Around the space, compressible tape should be applied, as well as perimeter columns, in order to form isolation joints
  • The product should be applied like a conventional cementitious floor laying mortar, in strips and then spread with a spatula
  • The laying of the mortar is done as in a conventional cementitious floor laying mortar
  • Spread the mixture, emphasizing the compaction of the surface, aimed at obtaining a homogeneous layer
  • Surface finishing should be carried out immediately after laying the product or within a maximum of 60 minutes
  • When carrying out this procedure, the surface of the mortar can be sprayed with water from a brush, so that the work is easier and faster, especially in the case of finishing with a metal disc
  • Removal of fresh debris from tools and application equipment can be carried out using water
  • Hardened material can only be removed mechanically
  • Mixing ratio 1.8 - 2.0 L of pure water per bag of 25 kg
  • Layer thickness 3 to 6 cm
  • Ambient temperature +5°C minimum / +35°C maximum
  • Substrate temperature +5°C minimum / +35°C maximum
  • Working time ~ 45 minutes*
  • Standby time/overlapping Walkability: ~12 hours*
  • Ceramic tile laying: ~24 hours*
  • Plating of natural stones or marble: ~ 72 hours **
  • Parquet layering: ~ 7 days ***
  • * Times have been calculated in ambient conditions of +23°C and 50% RH. Higher temperatures shorten these times. On the contrary, lower temperatures increase them
  • ** For natural stones and marbles with moisture sensitivity, the time should be extended to 7 days
  • The times have been calculated in ambient conditions +23°C and 50% RH, mortar thickness ≤ 5 cm and ventilation speed ≥ 2 m/sec
  • Consumption 16 - 18 kg/m2 per cm layer thickness
