Technical data sheet MONOFLEX-FB Measures for substrate preparation The requirements in DIN 18157 - 1 and the recognised technical standards are essential for preparing the application substrates.
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, ASO-Unigrund-K or ASO-Unigrund-PLUS. Prime non-absorbent substrates with ASO-Unigrund-S or ASO-Unigrund-PLUS.
Moisture content of the CM measurement
Application Mixing 1. 2. 3. 4.
Put the water into a clean mixing bucket and mix with the powder component with a stirrer to produce a homogeneous, lump-free mass. After a settling period of ca. 3 minutes, thoroughly homogenise the compound again. Do not mix more material than can be applied during the pot life. Do not mix with other cementitious mortars!
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.
Storage conditions Storage Store in a cool and dry place. Min. 9 months in the original canister. Promptly use opened container.
Disposal Product residues can be disposed of in accordance with disposal code AVV 17 01 01.
Notes 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 after DIN 18534, DIN 18531 and DIN 18535 must be protected by bonded waterproofing. Calcium sulphate screeds must be protected with the ASO®-Unigrund-GE, ASO®-Unigrund-K or ASO®-Unigrund-PLUS primers 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.
Relevant regulations 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.
