Grout “Ceresit CE 40” is a water-repellent mixture with antifungal effect and is intended for the treatment of joints between tiles. The width of the seams can reach 10 mm. Having visited the store, the consumer will find 32 colors for sale, including white. By purchasing this mixture, you will use a composition that is resistant to pollution and easy to clean. As practice shows, these qualities are very important, since sometimes you need to wipe the seams on the surface of the tile, which during operation will be exposed to negative external influences, and frequent maintenance is required to maintain cleanliness.
Main characteristics
Grout “Ceresit CE 40” is very resistant to deformation, has an elastic structure and is resistant to abrasion. It is ideally smooth, characterized by color stability, which is why the finishing material remains in its original form for a long time. Among the additional features can be distinguished frost resistance and water resistance. It is noteworthy that this mixture can be used even on underfloor heating, as well as during external and internal works, this makes the composition universal. For the external environment, this grout is completely safe, this can be said about the absence of negative effects on human health, however, when using the composition, it is important to observe the safety precautions, which will be discussed below. It provides for the need for personal protective equipment.
Area of use
Grout "Ceresit CE 40" is intended to fill the joints between tiles made of stone, ceramic, glass, marble. With this composition, you can close the seams on the walls and floors outside and inside buildings. Grout has high elasticity and can be used even on deformable substrates, this applies to drywall and particle boards. Moreover, the bases during operation can be subjected to temperature fluctuations, this applies not only to underfloor heating, but also to bathrooms, terraces, pools and open areas.
Ceresite CE 40 grout has hydrophobic qualities and was developed according to the MicroProtect formula, which indicates the high resistance of the material to mold and fungus. This composition is ideal for use in rooms with constant humidity, including kitchens, bathrooms and showers. If you have to fill in the corner joints, as well as the joints adjacent to the sanitary equipment, then use SC 25 silicone grout.
Recommendations for use: preparation of the mixture
Grout “Ceresit”, the colors of which are offered for sale in 32 versions, must be prepared before starting work. To do this, take a measured volume of pure water, the temperature of which can vary from 15 to 20 °. Gradually, the dry mixture should be added to the water, while the master should mix it until you can get a homogeneous mass without lumps.
If you have to work with a small amount of the composition, then you need to mix it manually, while significant volumes should be prepared using a construction mixer or a drill with a nozzle, while the tool should be set to a rotation speed in the range from 400 to 800 revolutions per minute.
Ceresite grout, the colors of which will satisfy even the most sophisticated consumer, should be prepared taking into account the exposure time, which lasts for 5 minutes. This pause is necessary for the composition to mature, after which it should be mixed again. Once the mixture is ready, it should be consumed in an hour, in case of an overdose of water, the technical characteristics of the mixture may deteriorate.
Seam filling
In the process of filling the joints, use a rubber spatula, with which it will be convenient to apply the mixture to the cladding, distributing it over the surface. The composition should be rubbed into the seams, and the excess should be collected with a spatula and repeat the operation. After 15 minutes, the surface is wiped with a damp and well-wrung sponge, which should be rinsed often. If the surface is excessively moistened, then this can cause a difference in color. Once the coating has dried, it can be removed from the surface of the tile with a dry soft cloth, but this should happen no later than eight hours after filling the joints. Ceresit CE 40 can come into contact with water after application after 7 days, a process pass is possible after 8 hours.
Additional usage tips
Ceresit CE 40 can be applied only after the deadline specified in the instructions for the adhesive used. If a cement-sand mixture was used for the installation of the finishing material, then the joints can be filled only 7 days after laying the tiles. In any case, the tile adhesive and surface must be dry. The edges of the seams must be cleaned of glue, grease and dust, as well as other contaminants that would prevent the adhesion of materials.
Before applying the mixture, the edges of the tiles are wetted with a damp sponge. Grout “Ceresit CE 40”, the instructions for use of which will allow you to avoid mistakes, should be applied only after removing the old grout. If you used stone, dull or unglazed tiles in your work, then you should first test for staining the material with pigments that are part of the grout. Application works are carried out at air and base temperatures ranging from 5 to 30 °, while the relative humidity should not exceed 80%.
If the moisture content of the base turns out to be elevated, this can cause a difference in color, this also applies to different volumes of water during mixing, as well as intensive smoothing of joints and uneven drying. If you want to avoid the Ceresit CE 40 Aquastatic varying in shades on the same surface, grout from the same batch should be used. When working, it is necessary to use tools made of stainless materials.
For reference
During the day after application to the grout joints, they should be protected from drying out, exposure to direct sunlight, heating and wind. During the week, you must exclude the effects of water, as for outdoor work. In this case, the master should provide protection from rainfall.
Safety precautions
The water-repellent grout contains cement, when interacting with water, an alkaline reaction is obtained, so the master should protect the skin and eyes. Quality indicators and recommendations will be true only if the ambient temperature is approximately equal to 20 °, and the relative humidity is 60%. Under other conditions, the quality of the material may vary.
Consumption and additional specifications
The consumption of the mixture may vary depending on the size of the tile and the width of the seam. Thus, if you use a square-shaped finishing material with a side of 5 cm, and the seam width is 2 mm, then the grout consumption is 0.5 kg / m 2 . If the width of the seam with the same dimensions of the tile increases to 3 mm, then the grout consumption will be 0.7 kg / m 2 .
When using square tiles with a side of 10 and 15 cm, the consumption is 0.4 kg / m 2 , which is true with a joint width of 2 and 3 mm, respectively. If you purchased products with sides equal to 10x20 and 20x20 cm, and the width of the seam will be 3 and 5 millimeters, respectively, then the consumption will be 0.4 kg in the first case and 0.5 kg / m 2 in the second case.
Some professionals are interested in such a characteristic as bulk density; at Ceresit CE 40 it is 0.95 ± 0.1 kg / dm 3 . But for the average consumer, it is very important how much water should be used per 1 kg of dry mix. The volume of liquid can vary from 0.32 to 0.33 liters.
Conclusion
Grout consumption CE 40 was mentioned above, but if you decide to use this composition in your work, then you may also be interested in frost resistance. This material is capable of undergoing up to 100 freezing and thawing cycles, but the operating temperature can vary from -50 to + 70 °.
