Check the application substrate and determine the moisture content using the CM method. <br />2. Remove impurities, adhesion-reducing substances and binder accumulations/laitance layers. <br />3. Prime absorbent substrates with ASO-Unigrund-GE, ASO-Unigrund-K or ASO-Unigrund-PLUS. <br />4. Prime non-absorbent substrates with ASO-Unigrund-S or ASO-Unigrund-PLUS. <br />5. Prime calcium sulphate screeds with a residual moisture content of max. 1.2 CM-% with ASO-Unigrund-PLUS.</p> <p>Application <br />Mixing <br />1. 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 />2. Do not mix more material than can be applied during the pot life.</p> <p>Application <br />1. Spread the mixed mortar evenly across the substrate surface and comb through with a suitable notched trowel to suit the board size. <br />2. Apply the surfacing materials within the adhesive open time. <br />3. For tile formats with an area of 0.25 m² or more per tile and/or an edge length of > 60 cm, a scratch coat should be applied to the back. <br />4. For laying on ‘green’ cement-based/calcium sulphate screeds, a scratch coat must be applied to the back. <br />5. When using a tile levelling system, the tightening wedge must be driven in or the rotating cap must be tightened within the bonding open time of <br />the applied thin-bed mortar.</p> <p>Cleaning tools <br />Clean tools thoroughly with water after use.</p> <p>Commissioning of floor heating systems <br />1. Underfloor heating can be put into regular operation after 7 days. <br />2. For coverings that were laid on ‘green’ cement-based screeds, the any existing floor heating system must be commissioned and documented in <br />accordance with the Schomburg MONOFLEX-S2 heating protocol.</p> <p>Emission behaviour / building certification systems <br />Very low emissions in accordance with GEV-EMICODE, which normally results in positive evaluations within the scope of building <br />certification systems in accordance with DGNB, LEED, BREEAM, HQE. <br />Maximum quality level 4, line 8 in accordance with DGNB criteria "ENV 1.2 Risks to the local environment".</p> <p>Notes <br />Laying tiles and natural stone coverings on ‘green’ substrates or cement-based screeds (< 28 Tage) mit einer erhöhten Restfeuchte von >2.0 <br />CM-% or calcium sulphate screeds with an increased residual moisture content of > 0.5 CM-%) is a special application which deviates from <br />the applicable recognised rules of technology and/or the relevant DIN standards. <br />When laying tiles in large or mega format, the tile manufacturer’s laying instructions and product data sheets must be observed. <br />When laying natural stone and synthetic stone, the product-specific properties of the coating materials (tendency to discolour, risk of curling, <br />etc.) and the laying recommendations of the manufacturer must be taken into account. We recommend carrying out trial laying! <br />Rooms, surfaces and building components that expect water exposure after DIN 18534, DIN 18531 and DIN 18535 must be protected <br />by bonded waterproofing. <br />Calcium sulphate screeds must be protected with the ASO®-Unigrund-GE, ASO®-Unigrund-K or ASO®-Unigrund-PLUS primers prior to <br />laying. Calcium sulphate screeds must be protected with a barrier primer (e.g. ASODUR®-GBM) when laying large format tiles. <br />Do not stir or add water to existing material that has already set in order to make it workable again. <br />Use a barrier primer such as ASODUR®-GBM to protect substrates that are sensitive to moisture, such as magnesite screeds, from direct <br />contact. <br />Protect the product from water, frost, draughts, direct sunlight and mechanical loads until it has dried completely.</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>SCHOMBURG GmbH & Co.
