The elastic waterproof grout Ceresit CE 40 is a colored grout intended for finishing joints when laying ceramic tiles and glass tiles, as well as natural or artificial stone. The mixture can be used for both indoor and outdoor use. Ceresit grout is used on vertical and horizontal surfaces. It is recommended for use on deformable substrates, such as particle boards , chipboard, drywall. In addition, it is used on surfaces subject to temperature fluctuations: on underfloor heating, terrace, outdoor pools, etc. Due to its hydrophobic properties and high resistance to fungi and mold, it can be used in rooms with constant humidity (bathroom, shower room, kitchen, etc.).
Ceresit grout: characteristics
According to the reviews of the builders, a seam up to 5 mm wide has the following qualities:
- A sufficiently high adhesive ability, including to a smooth surface.
- Elasticity (use for underfloor heating is possible).
- The increased water resistance.
- Resistance to mechanical stress and pollution.
- Surface smoothness.
- Resistance to fungus formation.
- Has increased resistance to detergents.
- The composition is suitable for outdoor and indoor use, as well as for swimming pools.
Mixture application
Ceresit grout is used, as a rule, for sealing joints between glass or ceramic tiles, as well as for those that arise when laying artificial and natural stone, such as marble. It can be used both on vertical and horizontal surfaces inside or outside the premises. Ceresit tile grout is recommended for use in places exposed to water (kitchens, bathrooms, showers, pools). Due to the high hydrophobic properties of the material (aquastatic effect), water droplets, unable to penetrate the structure of the material, roll off the surface. The mixture is recommended for use on surfaces subject to deformation: chipboard, drywall or on a heated floor.
Preparation of tiles for grouting
It is not allowed to start grouting the joints until the hardening of the tile adhesive on which the lining is applied has finished. The joints and ends of the tiles before the grouting process are cleaned of glue, dirt, dust and other substances that can reduce the adhesion of the grout mixture.
Performing trowelling
Ceresit dry grout dissolves with water at a temperature of + 16-28 ° C. 300-320 milliliters of water must be added per kilogram of the mixture, then stirred. After obtaining a homogeneous composition, wait 5 minutes and mix again. The consumption of dry mix is from 400 to 700 grams per square meter of cladding.
Recommended air temperature during work +20 ° C. 15 minutes after grouting, excess mixture is removed with a slightly moistened sponge. Dry grout can be removed with a dry soft cloth. If the temperature deviates from the recommended setting time and hardening of the grout may vary.
According to reviews, their abundant washing with water may adversely affect the performance of the seam. In the case of excessively intense mashing, roughness may occur on its surface.
Non-observance of the proportion of water and grout during the preparation of the mixture, as well as the effect of moisture on the base, which is covered with tiles, can lead to slight differences in the color of the seam.
During the first days after installation, fresh joints must be protected from precipitation, excessive moisture and low (less than +5 ° C) temperature. Full hydrophobicity of the grout is achieved after 5 days from the end of the work.
Negative effects on contact with the skin were not noted. If this mixture accidentally gets into your eyes, they should be washed with a large volume of water. If irritation occurs, seek medical advice.
Ceresit grout: shelf life and storage conditions
The duration of storage of the grout is 18 months, starting from the date of manufacture, which is indicated on the package. The material should be stored in dry rooms, without removing from the original sealed packaging.
Ceresit CS25 Sealant for Tile Seams and Joints
Features silicone grout, according to reviews, the following:
- High adhesion, including to smooth surfaces.
- Moisture resistance.
- Good elasticity.
- High resistance to fungus and mold.
- The grout is UV resistant.
- Used in indoor and outdoor use.
- The sealant is resistant to mechanical damage and contamination.
- The composition is not harmful to the environment.
- On sale there are 15 different colors to choose from + transparent.
Scope of use
Silicone grout for joints Ceresit CS25 is used as a sealant to impart moisture repellent properties, as well as to prevent the appearance of fungus and mold in the joints and joints of tiles in showers, latrines, bathtubs, etc.
According to reviews of builders, it is highly tenacious to materials made of glass, faience, porcelain and enameled surfaces. Thanks to the Trio protection formula, long-term protection against mold and mildew is provided, and its high UV resistance allows this sealant to be used even for outdoor applications.
Silicone grout Ceresit does not adhere to materials such as Teflon, bitumen, polyethylene, rubber, as well as to products that have the ability to release any oils, solvents, plasticizers. Avoid contact of the sealant with food products, mirror surfaces, limestone, marble surfaces and metal products that are susceptible to corrosion, since the material contains fungicides and acetic acid is released when it hardens.
