Green certifications
• Living Building Challenge (LBC) Red List Free: This product has been verified per the most current Red List on the LBC’s Website.
WHERE TO USE
• For leveling, smoothing and repairing of interior residential and commercial floors before the installation of floor coverings
• For use over radiant-heated floors or to encapsulate hydronic or electric radiant-heated floors

LIMITATIONS
• Do not mix with other self-leveling underlayments.
• Do not install over unprimed surfaces.
• Do not install over flooring products, adhesive residues or substrates containing asbestos.
• Do not use for exterior applications. For interior use only.
• Do not apply Novoplan DPL unless the substrate temperature is maintained at between 50°F and 90°F (10°C and 32°C) for 48 hours before, during and after application. Do not allow freshly installed Novoplan DPL to freeze.
• Do not use as a final wear surface. Cured Novoplan DPL must be covered with a finished floor system or floor covering.
• Do not install over standing water.
• Do not install over dimensionally unstable materials.
• Do not install if the maximum allowable deflection of the supporting surface exceeds L/360 (or L/720 for installations involving natural stone or their agglomerates) when exposed to live or dead loads.
• Do not use in areas subjected to prolonged exposure to moisture. Contact MAPEI’s Technical Services Department for waterproofing recommendations.
• Do not use as a moisture mitigation product. Cement-based self-leveling underlayments do not reduce moisture vapor transmissions emanating from high-humidity concrete slabs. If the flooring or installation system requires protection from elevated humidity levels, moisture mitigation must be done before Novoplan DPL is installed. Contact MAPEI’s Technical Services Department for recommendations regarding moisture mitigation.

SUITABLE SUBSTRATES
• Concrete that is installed in compliance with ASTM F710, that is at least 28 days old, and that is free from hydrostatic pressure, osmotic blistering and alkali silica reaction. Surface profiling of concrete is not required if Novoplan DPL will only be exposed to light or moderate traffic conditions. For high traffic, heavy rolling loads and maximum depth of fill conditions, an International Concrete Repair Institute (ICRI) concrete surface profile (CSP) of #3 to #4 is required beneath the selected primer. Alternatively, a textured primer may be used instead of mechanical profiling. Make sure to follow all written instructions and guidelines found on the Technical Data Sheet and other related documentation for the selected primer.
• Well-bonded and dimensionally stable ceramic tile, porcelain tile, quarry tile, natural stone, vinyl composition tile (VCT), cement, epoxy-based moisture barriers and epoxy terrazzo
• Properly installed cement backer units
• Durable and fully cured cement-based mortar beds
• Engineer-approved plywood or oriented strand board (OSB) subfloors with a maximum of 19.2" (48.77 cm) on center joist placement and that meets requirements of L/360
• Nailed-down wood flooring (including plank wood subfloors, strip wood subfloors and nailed-down solid wood flooring) that has been covered over with at least one layer of 5/8" (16 mm) plywood, glued and screwed
• Gypsum-based underlayments
• Mapeheat ™ Membrane, Mapeguard ® UM and similar crack-isolation and uncoupling membranes (these do not require priming)

SURFACE PREPARATION
• All substrates must be properly prepared, structurally sound, stable, solid, dry and primed with an appropriate MAPEI primer unless otherwise noted.
• On concrete substrates, fill in deep areas, holes and cracks with an appropriate MAPEI patching compound or screed. Fluid self-leveler may leak through to a floor below or other unwanted cavities.
• On plywood substrates, fill joints with an acrylic-based caulking compound to prevent the underlayment from leaking into a floor below. Refer to MAPEI’s reference guide “Surface-Preparation Requirements for Self-Leveling Underlayments” for details on proper surface preparation.

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 DPL 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.

PRODUCT APPLICATION
Read all installation instructions thoroughly before installation.
1. Substrates and ambient room temperatures should be maintained at between 50°F and 85°F (10°C and 29°C) during application as well as for 3 days before and after application.
2. Before product installation, close doors and windows, and turn off HVAC systems to prevent drafts during application and until the underlayment is cured. Protect installation areas from direct sunlight.
3. For full depth installations up to 4" (10 cm), use dams to section off areas of about 100 to 150 square feet (9.29 to 13.9 m2) to the desired level for easier placement.
4. Quickly pour or pump mixed self-leveling compound onto the surface in a ribbon pattern. Set the width of the pour at a distance that is ideal for maintaining a wet
edge throughout placement. For best results, work as a team to provide a continuous flow of wet material, to avoid trapping air or creating a cold joint. Apply enough
material to adequately cover all high spots.
5. Shortly after placing Novoplan DPL, use a gauge rake to spread the material and assist in gauging it to the desired depth. After achieving the desired depth, use a smoother to obtain an even surface.

CURING
• Novoplan DPL is self-curing. Do not use a damp-curing method, or curing and sealing compounds.
• Cool-weather conditions may extend curing or setting times. Warmer weather conditions may accelerate working, curing and setting times.

CLEANUP
• Wash hands and tools with water promptly before the material hardens. Cured material must be mechanically removed.

PROTECTION
• Protect Novoplan DPL from direct sunlight, excessive heat and drafty conditions during curing. Turn off all forced ventilation and radiant heating systems, and protect the installation for up to 24 hours after completion.
• Avoid walking on the installed surface for at least 6 hours after installation, depending upon temperature and humidity conditions.
• Protect the installation from traffic, dirt and dust from other trades until Novoplan DPL is completely cured and final flooring has been installed.
• Do not expose Novoplan DPL to rolling dynamic loads, such as fork lifts or scissor lifts, for at least 3 days after installation.
