Additional information

Composition

Product based on cement, selected aggregates and additives.

Features and applications

  • For thickening and leveling interior floors for pedestrian traffic, without the use of wheelbarrows. Not subject to impacts. Little traffic of light vehicles with smooth tires and with a maximum speed of 10 km/h.
  • Suitable for surfaces with under floor heating.
  • High self levelling power.
  • Easy to apply, achieving increased degree of flatness. 
  • High mechanical resistance.
  • Floor screeding between 10-60 mm.

Substrates

  • Concrete, mortar flooring, and similar.
  • Substrates must be resistant, stable, sound and clean, free of dust, remains of plaster, paint, demoulding agents, organic products, etc.
  • Prior to applying PAVILAND RECRECIDO AUTONIVELANTE, cavities and/or cracks in the substrate must be adequately repaired.
  • Before applying the product, it must be ensured that the residual humidity of the substrate is below the recommended level (less than 3%).
  • Apply the primer PAVILAND PRIMER R to avoid any air bubbles in the covering and to improve the adherence of the substrate.

Instructions for use

  • Define and mark out the maximum levels of the screed coat.
  • Mechanically mix the product with water (4,25-4,75 L per sack), with the help of a cement or mortar mixer at low revolutions (< 500 rpm) until a fluid, uniform paste is obtained (without lumps).
  • Let the mixture stand for 2 minutes.
  • Apply the mixed product by pouring or pumping over the bottom of area and spread with a levelling trowel, smoothing and correcting imperfections.
  • Once the product has been spread it is recommended to go over with a toothed roller to eliminate any air bubbles, go over again with the levelling trowel until a completely smooth area is obtained.
  • Thicknesses between 10-60 mm.
  • Respect structural joints and carry out perimeter and portioning joints.

Cautions and recommendations

  • Do not apply under 5ºC nor above 30ºC. 
  • Do not apply when there is a risk of frost, rain, strong wind or direct sunlight.
  • Do not apply on floor with humidity or with a risk of having it.
  • Not recommended for exterior use.
  • Do not add sand, cement or any other product that modifies the original formula.
  • Once the product has been mixed and the resting time has occurred, do not add additional water.
  • For floors with a larger surface area than 20 m2 or more than 10 lineal metres it is recommended to make partition joints, marking simple square sections with joints at least 6 mm wide, filling them with PUMALASTIC PU.
  • Avoid contact with perimeter elements through the execution of perimeter joints, which must be at least 6 mm wide and with a depth between 10 and 30 mm, filling them with PUMALASTIC PU.
  • Before placing the final coating, please verify through the residual humidity is <3% with a carbon hygrometer.

Packaging
