Features and Benefits

  • Ultraplan M20 Plus can be used for fast-track resurfacing and construction of horizontal wear surfaces.
  • This light gray product is designed to accept industrial/commercial sealers and coatings (verify compatibility and follow manufacturers’ instructions).
  • Ultraplan M20 Plus can be used for quick-turnaround leveling, smoothing and repairing of interior floors before the installation of floor coverings.
  • Ceramic tile and natural stone can be installed in as little as 3 to 4 hours after application.
  • Floor coverings – carpet, vinyl sheet goods, vinyl tile, vinyl composition tile (VCT), homogenous PVC, rubber, engineered wood plank, and polymer floor coatings and toppings – can be installed 16 to 24 hours after application.
  • Ultraplan M20 Plus may be used as a finish topping. However, due to the nature of polymer-modified cementitious materials, variations in color, stainability and general finish should be expected.
  • Ultraplan M20 Plus is not recommended as a surface for diamond polishing.
  • Ultraplan M20 Plus is tough enough for light industrial warehouse floors and loading docks subject to continual light vehicular and foot traffic (see “Limitations” section).

Ultraplan M20 Plus is an HCT (High-Hydrated Cement Technology) calcium-aluminate-based, quick-setting self-leveling, self-drying material. It is specially formulated for the resurfacing and construction of interior horizontal surfaces as a high-compressive-strength underlayment with maximum resistance to wheel tracking and indentations experienced in softer underlayments. Ultraplan M20 Plus is suitable for use as a commercial wear topping in warehouse and alternate industrial applications where an exceptional flat and smooth concrete surface is desired.


  • Do not install over substrates containing asbestos.
  • Ultraplan M20 Plus is quite fluid once mixed and can be installed easily from 1/8" to 2" (3 mm to 5 cm) in a single lift. For rubber-wheel traffic, the minimum thickness is 3/8" to 2" (10 mm to 5 cm).
  • Ultraplan M20 Plus has a compressive strength greater than 2,800 psi (19,3 MPa) after 1 day and 5,000 psi (34,5 MPa) after 28 days.
  • The cured surface of Ultraplan M20 Plus accepts most penetrating hardeners and densifiers and a wide variety of sealers, as well as epoxy and urethane coatings.
  • Ultraplan M20 Plus may exhibit slight color change from one manufacturing location to another, and from lot to lot. To minimize this effect, apply Ultraplan M20 Plus from the same manufacturing location and in consecutive batch numbers on a single floor when
    used as a topping.
  • Before application of Ultraplan M20 Plus, always properly prepare the surface and prime it with the appropriate MAPEI primer. See MAPEI's "Primers for Self-Leveling Materials" product selection guide and the respective current TDS for the desired primer.
  • Ultraplan M20 Plus is for use in dry, interior areas only. For exterior use or for areas subject to prolonged exposure to moisture, use an exterior-rated MAPEI topping or screed mortar.
  • Ultraplan M20 Plus can only be used between the temperatures of 50°F and 95°F (10°C and 35°C).
  • Provide for expansion and control joints where specified, including the perimeter of the room, columns, supports and equipment pedestals. Do not bridge expansion and control joints. Ensure that such joints are honored completely through the Ultraplan M20 Plus and primer.
  • Where control or expansion joints do not exist in the substrate, provide for them in the system.
  • When used as a topping, Ultraplan M20 Plus is intended for foot traffic, rubber-wheeled forklift traffic and similar uses. Steel-wheeled and small-wheeled (high-pointloading)
    as well as hard-wheeled traffic, or dragging sharp or heavy metal objects over the floor, will cause indentations, gouging or similar damage.
  • Ultraplan M20 Plus is not suitable for such excessive service conditions, heavy manufacturing, chemical or industrial applications.
  • Failure to honor existing joints may lead to the formation of hairline or larger cracks in the underlayment, as well as disbonding of the underlayment.
