SUBFLOOR

Features

Applications

  • Leveling mortar, used as substrate for other floor finishes.
  • Final floor mortar for cemented type.

Note

  • Cannot be used for ceramic tile setting.
  • Cannot be used for making concrete.

The mortar must be prepared following the packaging instructions, adding the amount of water recommended by mechanical mixer, which may also be mixed by hand in the mortar box. The mortar must present a humidity content of a slightly damp consistency, allowing application by compression.


Working Time




The subfloor industrialized mortars must not be used 2 hours after the preparation time.
 


Use

  • Less than 40 mm thick: first, a bonding bridge must be prepared between the substrate and the subfloor, applying a cement grout and spreading it around with a broom. While the coat is still damp, the subfloor mortar must be used, spreading and compacting it with the mortar hoe, then leveling and troweling.
  • More than 40 mm thick: the subfloor must be prepared with 40 mm coats, and, after compacting the first coat, the second coat must be applied immediately and be compacted, leveled and troweled.
  • When preparing the subfloor, it is important to keep in mind the construction details: level, slope, presence of joints and corners rounding for the application of waterproofing.
