Tools and products for an excellent workability of DEKOGROUT-2K: • DEKOGROUT-2K non-absorbent, two components, adhesive-grout, acid, bacteria, stain and mould resistant. • Hard rubber grout float for an accurate filling of sealant into the joints. We recommend exerting a reasonable pressure, so that the product will penetrate deeply in empty spaces. The hard spatula allows the filling at the tile level, avoiding the unpleasant effect of voiding the joints. • DEKOFELT mildly abrasive felt, used to emulsify the grout before cleaning with a sponge. Consider a consumption approximately of 1 felt every 4 m2 for the application of mosaic, and 1 felt every 15 m2 for gres in big format. DEKOSPONGE: sponge in cellulose, particularly soft for the accurate cleaning of the fresh product. Consider a consumption approximately of 1 sponge every 4 m2 for the application of mosaic, and 1 sponge every 15 m2 for gres in big format. • 2K-CLEANER is a specific cleaner for alkali based, epoxy grout. METHOD OF USE: Before starting: Epoxy joint should be cleaned in short time before the application to get an excellent result. For this reason we recommend to consider at least two persons, who, at the same time, can grout the joints and clean the grout excess with felt and sponge. Environmental conditions: To execute a good work with DEKOGROUT-2K temperature is very important; it has a great influence on the times of workability of the product and on the times of crossing on the floor; For this reason, during the application of the system, the temperature must be between 12° and 30°C. Protect the surfaces from strong sunlight, airflows, strong wind and high relative humidity. In any case, we recommend to stock DEKOGROUT-2K at a temperature between 15° and 25°C during 24 hours before use. This expedient improves the workability, reducing fatigue during application. PREPARATION OF THE MIXTURE: The supports must be fixed and incapable of being deformed, not free to move except for fluctuations and elastic vibrations typical of the structures. Drywalls and thin prefabricated boards are not suitable as supports. Grouted joints must be cleaned accurately before de application and the residual cement on the whole thickness of the tile and the surface must be free from any trace of dust, oil or anti-adhesive substances. Furthermore, it is essential that grouts and mortars used for application are dry (see times declared by the producer in the technical data sheets). For adhesives of the brand Benfer, respect the following waiting times (at + 23°C, 50% relative humidity): NORMAL SETTING ADHESIVE : 12 hour RAPID SETTING ADHESIVE: 3 hours. Pay particular attention to the grouting of ceramic material, especially polished, because the superficial glazing can be removed and resulting more absorbent to grouts in general. We recommend to protect the surfaces with specific products before the grouting. For any doubt, make a test on a small surface before proceeding, and consult the supplier before starting to work, anyway.

PREPARATION OF THE MIXTURE: DEKOGROUT-2K is available in 2,5 kg and 5 kg bucket that contains 2 pastes, that are pre-dosed in the right ratio, to be mixed entirely in the original packing with clean and dry tools, until you obtain a homogeneous paste, using, in case, a spatula to scrape from the bucket the material that was not perfectly mixed. We recommend to use a low-rev electric mixer and a highly resistant tool (better if made of steel) with a helix with a diameter lower than 9 cm. It is absolutely forbidden to add water to the product, from which it would be irredemably damaged. When opting for the clear version with glitter, after having thoroughly mixed part A with part B, slowly pour all the contents of the glitter pack continuing to mix and using a spatula to scrape the product from the sides of the container until the perfect result is obtained. During the mixing, the setting and the sponge-cleaning operations, always use protective gloves and glasses, because paste B is irritant for the skin. APPLICATION OF DEKOGROUT-2K AS A GROUT: Spread DEKOGROUT-2K with a hard rubber grout float by exerting a reasonable pressure, so that the product will penetrate deeply, then remove accurately the excess grouting parts with rubber grout float in diagonal way. In the meantime the second worker will start immediately the cleaning process. Prepare two containers with lukewarm clean water, apt for this purpose. Squeeze DEKOFELT, a medium-hard felt, imbued of water, on the tiles and emulsify the grout with circular movements. It is necessary to rinse frequently the felt to remove the excess grouting parts and to add water on the treated surfaces. Finally remove residual material with DEKOSPONGE, soft sponge in cellulose, to be rinsed frequently in fresh water. We recommend to use the sponge moving it on joints at 45°C to avoid the removal of grout as much as possible. Cleaning after application: To execute a good work it is very important to clean within few minutes after grouting because, as explained before, because if you delay too long, the cleaning operation would become too difficult. Subsequently, do not walk on the fresh floor for 24 hours to avoid to drag under the shoes the fresh product (still not dry) all over the surface. An accurate cleaning operation after application is recommended anyway, in particular the day after, even following the really first cleaning. Apply DEKOGROUT-2K CLEANER all over the tile floor and leave it for about 15 minutes. Then emulsify the product with DEKOFELT, a medium-hard felt, and clean the floor with a soft dry cloth. With this operation all the residual excess, even the most impalpable, will be removed.

APPLICATION OF DEKOGROUT-2K AS ADHESIVE: Spread DEKOGROUT-2K with a notched metallic spatula, suitable for the tiles to lay. In interiors, apply the tiles by exerting a reasonable pressure, so that the contact with the adhesive will be, at least 80% of the wall surface; at least 95-100% for floor tiles. In exterior, in damp areas or inside tanks, the contact with the adhesive must be 100%. At 23°C the open time is about 50 minutes and the duration of the mixture in the bucket is about 45 minutes. In adverse conditions (with extremely high room temperature, ex. : 30°C), the cited periods of time may be considerably reduced; in this case, we recommend the use of the product within 30 minutes, applying gradually and avoiding the application when the product results too dense or thick inside the bucket. Floors created with DEKOGROUT-2K can be walked by with caution after about 24 hours for grouting, completely walkable after 4 days in presence of temperature of 23°C. In case of temperature lower than 15°C we discourage the application. FULL SERVICE: The full service of the finished floor depends on the weather conditions. Consider that at temperature of 23°C ( ideal value of an easy application) the time of walkability is 24 hours, while at 15°C is 36 hours. Before the full service verify if the product inside the joints has hardened completely. ADVICE: • Always provide a grout of proper dimensions. The adequate minimum width for floors and tiles in interiors is 2 mm, for external floors and walls is 5 mm. • Although it is more deformable compared to a cementitious grout, DEKOGROUT-2K is not an elastic product, so, in floors in interior areas, you need to consider expansion joints every 25 m2 and 9 m2 for floors in dark colors, up to maximum 12 m2 for light colors, always repeating the fraction joints of the screed on the floor, as well as the structural joints. • The expansion joints must be filled with silicone DEKOSIL or a polyurethane sealant DEKOFLEX, removing all the material that may affect the adhesion strength before the application. • During the first 24 hours, always protect the finished and grouted covering from weather agents, such as strong sunlight, wind, rain etc… • Protect all the areas which are not to be treated from the effects of DEKOGROUT-2K. • Due to its granulometry, DEKOGROUT-2K is suitable for sealing joints from 1 mm wide. • Do not use DEKOGROUT-2K in presence of water inside the joints, with residual cement, oil or dust on the tiles. • Do not use dark colors on Klinker which is not glazed. • Contact the supplier before starting to work with the grouting absorbent materials with DEKOGROUT-2K. • Do not wash DEKOGROUT-2K with acid substances or strong oxidants during application. This may inhibit the hardening process of the material. • Avoid standing cleaning water on the freshly made grouts. • The prolonged contact with acid or oxidant products may modify the color of grouting.
