The wet drainage mortar must be protected from drying out too quickly, e.g. due to heat or draughts.</p> <p>SCHOMBURG GmbH & Co.

Distribute and compact the drainage mortar onto the prepared substrate. <br />2. Apply drainage mortar evenly and at a gradient of at least 1.5%. <br />3. Limit field sizes to a maximum field length of 6 m using bay sizing joints. Compact field sizes with a ratio of 2:3 are desirable. <br />4. Apply MONOFLEX, MONOFLEX-XL or UNIFIX-S3 to the back of boards using an 8-10 mm notched trowel and lay them on the still fresh <br />drainage mortar. <br />5. Alternatively, after approximately 24 hours, tile and slab coverings can be laid on the hardened drainage mortar using the buttering method with <br />MONOFLEX, MONOFLEX-XL or UNIFIX-S3. <br />6. Create the joints between the tiles with a minimum joint width of 3 mm and, after the tile adhesive has become ready for grouting, seal them with <br />a drainage-capable CRISTALLFUGE-DF or CRISTALLFUGE-HF cement-based sealant.</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>Notes <br />Do not add any additives and substances! <br />Observe the technical data sheets of the products mentioned before starting work. <br />Low temperatures, high humidity and heavy layer thicknesses delay hardening, drying and extend the time until ready to receive tiles. (Also <br />see the BEB data sheet “Building climate preconditions for drying screeds”). Tests showed that the crystalline binding of the water is slower at <br />low temperatures (+5 to +10°C), meaning that the screed was only ready to receive tiles after a longer period of time! <br />The quality of the aggregate used is partly decisive for the properties of the mortar produced with it. If aggregates with a different grading <br />curve and grain size are selected, the properties change. <br />Do not add any other cement or binder! <br />Border, field, building separation and movement joints should be carried over to or installed at the designated location; suitable means (e.g. <br />edge strips) should be used to detach them! <br />The installation location must be ventilated. However, draughts and direct solar radiation should be avoided during application and the <br />hardening process. The indoor temperature and floor temperature must be at least +5°C during application, and during the following week! <br />Air dehumidifiers may not be used during the first 3 days! <br />If moisture rises from the substrate, effective waterproofing is essential prior to laying the screed! This does not apply in conjunction with <br />coatings in the drainage mortar on an unbound cementitious base layer. <br />When laying on a bonded base layer (e.g. concrete) or waterproofing, the substrate must be created with adequate falls and be level to <br />prevent waterlogging.</p> <p>Relevant regulations <br />Planning, inspection of substrates and building site circumstances, laying, grouting and subsequent <br />care of the work must be done in accordance with the relevant DIN standards and recognised rules of <br />technology (e.g. the ZDB Data sheets of the Zentralverband Deutsches Baugewerbe e.V.(German <br />construction Association) in the latest version. <br />Observe applicable safety data sheet!</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.
