Next, clean the tiled finish damp. <br />3. The bedding mortar must be fully set, as otherwise, joint discolourations may occur. <br />4. Pre-moisten strongly absorbing coverings with water equally. <br />5. Joint edges must be clean and free of separating substances. <br />6. The time of tile grouting depends on the thin-bed mortar used. <br />7. In the event of thick-bed laying, the mortar bed must be sufficiently firm and evenly dry. <br />8. Do not grout on surfaces with different surface temperatures (e.g. due to sun exposure).</p> <p>SCHOMBURG GmbH & Co.

The consistency of joint mortar must be specified depending on the absorbency of the laying material and substrate. <br />2. The mix ratio must be kept the same in order to avoid colour differences. <br />3. Fill the water into a clean mixing bucket and mix with the powder component with a stirrer to produce a homogeneous, lump-free mass. <br />4. The mixing time is ca. 2 - 3 minutes. <br />5. After a settling period of ca. 3 minutes, thoroughly homogenise the compound again. <br />6. Do not mix more material than can be applied during the pot life.</p> <p>Application <br />1. CRISTALLFUGE-HF is added to the wall and floor areas with a suitable jointing board by exerting slight pressure. <br />2. Strike off diagonally to the joint cleanly so that the joint cross-section is filled totally. <br />3. After applying the grout (check with a finger test), wash the contours of the joint with a moistened sponge board. <br />4. Wash off again with the sponge board after a few minutes. <br />5. Keep expansion joints free for elastic grouting with ESCOSIL-2000. <br />6. Scrape out mortar residues after the mortar has sat and wash away with a slightly damp cloth. <br />7. After a few hours, wash off any mortar residue with a sponge board and clean water. <br />8. Do not use a dry cloth when cleaning, as this poses a risk of discolouration due to rubbing dried joint mortar into the joint that is still wet! <br />9. The fresh grouting must be protected from influences that damage drying, such as high temperatures, wind, rain, or frost. <br />10. If weather conditions are poor (low humidity, draughts, wind) and the ceramic shards are highly absorbent, the joint cross-section must be cured <br />with clean water (re-wet with the sponge board). <br />11. Replenish the cleaning water on a regular basis. <br />12. We recommend performing trial jointing (pre-wet the surface if necessary or impregnate with suitable materials prior to grouting) on coatings with <br />profiled, rough, unglazed or porous surfaces. <br />13. The washing time depends on the coating material and the prevailing climate. <br />14. After sufficient standing time, smooth the surface slightly without washing the joint out.</p> <p>Cleaning tools <br />Clean tools thoroughly with water after use.</p> <p>Storage conditions <br />Storage <br />Store in a cool and dry place. Min. 12 months in the original canister. Promptly use opened container.</p> <p>SCHOMBURG GmbH & Co.

(Risk of <br />inadequate strength development) <br />We recommend using neutral or slightly alkaline cleaning materials in the prescribed application concentrations for regular care and <br />cleaning on the grouted surfaces. Rinse the surface with clean water after cleaning. <br />The applicable regulations must be observed if cleaning materials containing acid are used! Pay attention to the product-specific properties <br />of the laying materials! Pre-dampen the joints and then apply the cleaning materials at a low application concentration. The cleaner's action <br />time must be kept to a minimum. Then wash it off with a large amount of clean water. Cleaning materials containing acid impair the joint <br />mortar’s strength and can even destroy the grout matrix totally if used improperly, e.g. doses that are too high, excessive action times or no <br />pre-wetting the grout net. <br />Only use clean water and clean tools! <br />Clean the grouted surfaces including the joint chambers thoroughly before starting grouting. <br />Observe the setting times for adhesive and mortar! Premature grouting poses the risk of uneven colours in the grout finish. <br />Protect the freshly applied joint mortar from sunlight, high temperatures, draughts, moisture and frost (until it reaches its final strength). <br />Close joints between covering fields, assembly parts, pipe penetrations and corner and connecting joints elastically using ESCOSIL-2000-ST <br />or ESCOSIL-2000 depending on the application! <br />Uneven moisture penetration due to the sub-base, mortar bed, temperature differences or coating material can cause colour variations in the <br />grout finish. These do not affect the joint mortar’s quality and can be rectified increasingly by favourable ambient conditions. For this reason, <br />the coloured appearance of the joint same rods may differ from the actual joint colour. No guarantee for differences in colour! <br />If there are higher mechanical loads, e.g. due to cleaning devices or chem. exposure, we recommend using the ASODUR®-EKF or <br />CRISTALLFUGE-EPOX heavy-duty, 2 component epoxy resin joint as the joint material if the production-specific properties of the natural stone <br />material allow this! <br />When grouting natural and synthetic stone tiles, take into account the specific properties (tendency to discolour). Perform trial jointing if in <br />doubt!</p> <p>Observe applicable safety data sheet! <br />Explanations <br />Colours <br />Cement grey <br />Medium grey</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
