Mapei Novoplan HFL 50lb Bag High Flow Self-Leveling Underlayment

Novoplan HFL is a self-leveling, calcium-aluminate-based underlayment and repair mix for interior concrete and engineer-approved floors with high-flow characteristics.

MIXING Before product use, take appropriate safety precautions. Refer to the Safety Data Sheet for details.

1. Based on the number of bags to be mixed, measure and pour the required amount of water (see “Mixing ratio” in the chart below) into a clean mixing vessel such as MAPEI Self-Leveling Mixing Barrel or a plastic pail that can hold at least 5 U.S. gals. (18.9 L). For best results, the water temperature should be at about room temperature (70°F or 21°C). The mixing ratio must remain consistent; do not overwater the mixture.

2. Slowly add the powder into the pre-measured water, taking care to not generate excessive dust. Use a high-speed drill and an oval paddle mixer to mix Novoplan HFL to a homogenous, lump-free consistency.

3. Continue to mix for 2 to 3 minutes. Do not overmix: Overmixing or moving the mixer up and down during the mixing process could trap air or cause pinholing during the application and curing process.

Mixing time: 2-3 minute, Flow time 30-45min
