HDA / Self-Leveling, Fast-Setting Mixture for Wooden Floors

Details:

• Type: Fast-setting self-leveling compound.
• Application Areas: Designed for floor installation (3 - 20 mm thickness).
• Composition: Contains reinforcing fibers.
• Functionality: For leveling full and partial horizontal surfaces.
• Base Materials: Suitable for wood fiber boards, wooden, and concrete substrates.
• Heated Floors: Usable on heated substrates.
• Base Material: Cement-based.
• Preparation: Prior to applying the finishing layer.

Application Instructions:

• Surface Preparation:

  • The substrate must be dry and solid, with all cracks and voids filled.
  • Clean the substrate from less durable and/or loose layers.
  • Use acoustic mats where the floor connects to walls, columns, etc.
  • The spacing between beams should be < 65 cm, with board thickness < 20 mm.
  • Wooden surfaces should be primed with SAKRET UG primer (in concentrated form). OSB boards should be primed with SAKRET QG primer. If in doubt, perform priming and HDA application on a small test area.
  • Absorbent surfaces should be primed with SAKRET UG primer (diluted at a ratio of 1:2).
  • Dry and especially absorbent surfaces should be primed twice!
  • Note: Using SAKRET HDA on gypsum or anhydrite substrates is prohibited!
  • When using SAKRET HDA on heated floors, heating must be turned off 5 days prior and should not be turned on for 28 days after material installation.

• Usage:

  • Mix SAKRET HDA in a clean container with cold water until a homogeneous lump-free mass is achieved. It is recommended to use a mixer with 600 RPM.
  • After a maturation time of approximately 3 minutes, remix the mixture.
  • Pour the compound onto the prepared surface (layer thickness > 3 mm) and level it with a needle roller.
  • Do not fill deformation joints with the leveling compound.
  • When leveling the substrate, an acoustic material should be integrated around the perimeter.
