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. <br />4. Prime non-absorbent substrates with ASO-Unigrund-S.</p> <p>Moisture content of the CM measurement</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. After a settling period of ca. 3 minutes, thoroughly homogenise the compound again. <br />3. Do not mix more material than can be applied during the pot life. <br />4. Always clean the mixing container, as setting CRISTALLIT®-FLEX-max acts as a catalyst. <br />5. Do not mix with other cementitious mortars!</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.</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 />Not suitable for areas submerged under water! <br />Protect surfaces that are not to be treated from the effects of CRISTALLIT®-FLEX-max! <br />When used in exterior areas, be sure to use suitable Schomburg sealing materials. <br />When using in rooms exposed to moisture penetration, note the required use of Schomburg sealing materials. <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 />When laying large formats larger than 50 × 50 cm, use a scratch coat on the back or lay using the floating-buttering method. <br />Do not add water or new mortar to existing CRISTALLIT®-FLEX-max mortar that has already set in order to make it workable again. (Risk of <br />inadequate strength development) <br />In the case of magnesia screeds as a substrate, these must be protected in advance by using ASODUR®-GBM. Danger of magnesite <br />pouring. <br />When laying covering materials larger than 60cm × 60cm on calcium sulphate screeds, we recommend using ASODUR®-GBM.</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.
