DM Standard Leveling Compound

Key Facts

Ceresit DM

Standard leveling Compound

For 0.5 - 10 mm layer thickness in one single application

 

Properties

  • Self-leveling and pumpable
  • Fast drying
  • Good ultimate resistance

 

Description

Ceresit DM is a mortar with self-leveling properties. Hydraulic cement-base compound, selected silica sands and special additives, that when mixing them with water form a fluid and self-leveling mass, ideal to correct imperfections in floors where thicknesses of up to 10 mm are required. Ideal for correcting flaws on several surfaces such as concrete, plaster or cement mortars, ceramic tile, natural stone, and old substrates with firmly stuck adhesive residues. 

For indoor use only.

Do not use it for traffic surfaces exposed to wear.

Step by Step

Substrate preparation

The substrates must be clean, crack-free, sound, dry, and free of substances that may impair adhesion and must comply with the current relevant local standards. 

 

Before applying the leveling compound, pretreat the surface with the recommended primers Ceresit R 777 or Ceresit R 766. For further information, see the technical datasheet.

Mixing

To prepare a bag of 25 Kg (55.12 lb.), measure and pour 6 L (1.59 gal) of water in a vessel. While stirring, pour bit by bit a bag of Ceresit DM. Use a mixer or a drill with approximate speed of 650 rpm, fitted with blades or proper disks.

Mix for 2 minutes and stop mixing, scratch the vessel walls and bottom and mix 2 minutes more until obtaining a fluid mixture free of lumps.

Application

Pour the self-leveling mixture by sections and uniform cuts in a determined area.

Distribute the mixture with a toothed squeegee or trowel and uniform the thickness. Simultaneously, on the self-leveling coat, roll repeatedly with spiked roller; this will also help to better distribute the product. Let it dry for approximately 4-6 hours to be ready for foot traffic, and 24 hours to be able to apply the desired finish.

Note. When passing the spiked roller, the maneuver shall be carried in a maximum time of 20 minutes after applying Ceresit DM, as the product starts its setting and loses its leveling properties.
