Suitable for the repair and levelling of interior floors, both on new and existing substrates, up to a thickness of 20 mm. Levelling and smoothing of floors prior to laying all types of flooring (carpet, ceramic, wood, linoleum, etc.) where high mechanical resistance and a fine finish are required. Suitable for levelling on concrete, mortar, tiles, ceramics, natural stones, etc.

• Preparing the substrate: Fill any small gaps or holes with the same mortar. To achieve a perfect finish and excellent planimetry in large works, spread flat feet evenly over the entire surface. Spread the product over the substrate in a single pass using a metal smoothing trowel with back-and-forth movements. On non-porous substrates, ceramic or polished concrete, apply a primer of FIXMAR PRIMER GR beforehand.

• By hand: Mix a 25 kg bag of L-20 plus with 5.5 to 6 litres of water using an electric mixer until you obtain a fluid, homogeneous paste. Leave the mixture for 3 to 5 minutes, then mix again before applying. Adjust and smooth with a levelling trowel.

• Mechanically: Adjust the pressure with water corresponding to the type of machine, until you obtain a very fluid paste. The desired height, marked on the levelling feet, is obtained by beating the product, giving the mortar oscillations so that the mortar itself levels itself.

• Respecting the mixing water.
• Respect expansion joints, structural perimeter joints.
• Apply between 5º and 35ºC. In cold season, use mixing water with a temperature higher than 10ºC.
• Protect from draught and sun during the first hours after application.
• Do not apply on floors with permanent humidity.
• In order to apply a second coat, the first coat must not be completely dry, otherwise apply a primer with Fixmar GR.
