Flexutal strength after 28 days (ASTM C349): ≥ 5 MPa

Notes: All above technical properties are tested in the standard experiment conditions with temperature of 25oC and moisture of 50%.

SURFACE PREPARATION
The minimum tensile of the applicable concrete substrates must be no less than 20 N/mm2. The surface must be solid and completely clean and free from dust, grease and impurities.

MIXING METHOD
Water consumption is about 22 – 24% of total volume of Neomax® Leveling 21. It is necessary to use 5.5 to 6.0 liters of water for 1 bag (25kgs) of dry product.
Use an electric mixer at speeds of 400-600 rounds/minute to mix the product;
Pour the needed volume of water into the mixing bucket, then slowly adding Neomax® Leveling 21 while keeping stirring thoroughly;
Mixing time is about 5 minutes until we get a homogeneous mixture.

WORKING
To meet the highest adhesion between the substrate and mortar layer, priming with Neomax® Primer 21 with the rated consumption of 0.2 - 0.4 liters/m2;
When Neomax® Primer 21 is still wet, applying Neomax® Leveling 21 with the support of a dedicated wiper or sprayer until the desired thickness is met;
Using spiked roller to break all remaining air bubbles;
Maximum thickness of one layer is 5mm. In case two or more layers are required, it is necessary to apply a Neomax® Primer 21 layer before making the next mortar layer;
Allowable working time is about 30 minutes at 25±2°C.
