Technical Datasheet MONOFLEX-S2 Suitable substrate Firmly adhering tiled finishes Concrete, cement screed (CT), floor levelling compounds, calcium sulphate screeds (CA, CAF), mastic asphalt screeds (AS), magnesia screeds (MA) Cement-based plaster, gypsum plaster, cement-lime plaster, lightweight plaster Tile bearing elements, gypsum fibre boards, gypsum boards, raised floors, cement and fibre cement boards, decoupling mats & panels, dry screeds Bonded waterproofing; the suitability of the substrate must be checked and observed, taking into account the planned water impact class of DIN 18534 and DIN 18531.
Substrate preparation Requirement for substrate 1. 2. 3. 4. 5. 6.
Load-bearing Dry Even Sealed in the surface Free of cracks Free of adhesion inhibiting substances and laitance layers
Preparing the surface 1. 2. 3. 4.
Check the application substrate and determine the moisture content using the CM method. Remove impurities, adhesion-reducing substances and binder accumulations/laitance layers. Prime absorbent substrates with ASO-Unigrund-GE or ASO-Unigrund-K. Prime non-absorbent substrates with ASO-Unigrund-S.
Usage Mixing 1. Put the water into a clean mixing bucket and mix with the powder component with a stirrer to produce a homogeneous, lump-free mass. 2. Do not mix more material than can be applied during the pot life.
Application 1. Spread the mixed mortar evenly across the substrate surface and comb through with a suitable notched trowel to suit the board size. 2. Apply the surfacing materials within the adhesive open time.
Cleaning tools Clean tools thoroughly with water after use.
Inbetriebnahme von Fußbodenheizungen Storage conditions Storage Store in a cool and dry place. Min. 12 months in the original canister. Promptly use opened canister.
Disposal Product leftovers can be disposed of in accordance with disposal code AVV 17 01 01.

Technical Datasheet MONOFLEX-S2 Notes When laying tiles and natural stone coverings on young substrates or cement screeds (< 28 days) with an increased residual moisture of >2. 0 CM-%, this is a special construction that is subject to the applicable recognized rules of technology and/or the relevant DIN standards. When laying tiles in large or mega format, the tile manufacturer's laying instructions and product data sheets must be followed. When laying natural stone and synthetic stone, the product-specific properties of the coating materials (tendency to discolour, risk of curling, etc.) and the laying recommendations of the manufacturer must be taken into account. We recommend carrying out trial laying! Rooms, surfaces and building components that expect water exposure in accordance with DIN 18534, DIN 18531 and DIN 18535 must be protected by bonded waterproofing. Calcium sulphate screeds must be protected with the ASO®-Unigrund-GE or ASO®-Unigrund-K primer prior to laying. Calcium sulphate screeds must be protected with a barrier primer (e.g. ASODUR®-GBM) when laying large format tiles. Do not stir or add water to existing material that has already set in order to make it workable again. Use a barrier primer such as ASODUR®-GBM to protect substrates that are sensitive to moisture, such as magnesite screeds, from direct contact. Protect the product from water, frost, draughts, direct sunlight and mechanical loads until it has dried completely.
Planning, inspection of substrates and building site circumstances, laying, grouting and subsequent care of the work must be done in accordance with the relevant DIN standards and recognised rules of technology (e.g. the ZDB sheets of the Zentralverband Deutsches Baugewerbe e.V.) in the latest version.
