Description

Ceresit DX Xpress is a mortar with self-leveling properties and shrinkage free composed by hydraulic cement, selected silica sands and special additives. Upon contact with water during the mixing operation, it forms a fluid mass perfect for correcting imperfections on concrete flooring. It is perfect for correcting imperfections in building sites that require high performance like airports, warehouses, hospitals, hotels, museums, restaurants and much more.

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 and Ceresit R 766. For further information, see the technical datasheet.

Mixing

For the preparation of a 25 kg (55.12 lb.) bag, measure and pour 5.5 liters (1.45 gal) of water in a container. By stirring up, slowly add a Ceresit DX Xpress bag. 

Mix for 2 minutes, stop the mixing, scrape the walls and the bottom of the mixing vessel and mix for 2 more minutes until you get a smooth mixture free of lumps.

Application

Pour the self-leveling mixture by sections and uniform parts. 

Apply the leveling compound with a toothed squeegee or smoothing trowel to achieve a uniform thickness. Pass a roller repeatedly in both directions; this also helps to have a better product distribution. Let it dry for about 2 to 3 hours for foot traffic, and 8 hours to apply the desired finish.

Note. While passing the spikes roller, it is necessary that the task will be done in maximum 10 minutes after the application of Ceresit DX Xpress.
