Suitable substrate Dry screeds Raised floors Tile bearing elements Firmly adhering tiled finishes Gypsum boards Gypsum fibre boards Cement and fibre cement boards 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 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.
Preparing the substrate Requirement for substrate 1. Dry 2. Load-bearing 3. Even 4. Sealed in the surface 5. Free of cracks 6. Free from negative pressing water 7. Free of adhesion inhibiting substances and laitance layers
Preparing the surface 1. Check the substrate and determine the residual moisture content using the CM method. 2. Remove impurities, adhesion-reducing substances and binder accumulations/laitance layers. 3. Prime absorbent substrates with ASO-Unigrund-GE or ASO-Unigrund-K. 4. Prime non-absorbent substrates with ASO-Unigrund-S. 5. Level surface irregularities in the substrate before starting waterproofing work using a cementitious levelling compound that is suitable for the application (e.g. SOLOCRET-50 or ASOCRET-M30).

Technical data sheet SANIFIN Formation of intersections, movement and connecting joints Use the ASO-Dichtband 2000 - System or the ASO-Dichtband-System along with the required pre-formed pieces to form movement and connecting joints, as well to integrated intersections and assembly parts. The joint sealing tape and the pre-formed pieces are embedded in the first layer of waterproofing material and covered with the second layer. Transitions and or connections between joint sealing tapes and preformed pieces must be formed with an overlap of 50 mm. Check elements such as linear drainage systems for suitability in advance and include them in the bonded waterproofing in accordance with the manufacturer’s specifications.
Structure in the water exposure classes W0-I to W2-I in accordance with DIN 18534-5 and ZDB leaflet [*1] 1. Prepare the substrate according to the substrate requirements. 2. Cut SANIFIN to the appropriate size. 3. Comb the system adhesive or the bonded waterproof system out to around 10 cm wider than SANIFIN. 4. Insert the strip into the adhesive bed. 5. Press the strip into the adhesive bed using a flat trowel or roller so that there are no voids and no wrinkles. Ensure that the bedding and crosslinking covers the whole area from the fleece to the adhesive. 6. Lay the strips that were cut to size with an overlap of at least 5 cm. Glue the strips in the overlap area with the thin-bed mortar or cementitious waterproofing used. 7. Tiles or boards can be laid in the floor area as soon as the thin-bed mortar or the cementitious waterproofing that was used to lay SANIFIN has hardened sufficiently; this is normally on the next day. Tiling on the walls can be performed on SANIFIN with MONOFLEX-XL; MONOFLEX-XL can also be used for laying in the floor areas if necessary due to the mechanical and chemical load. The planner must provide the load type and intensity specifications. The Technical Service department at SCHOMBURG GmbH will be happy to assist in these cases.
Construction in wear class C 1. Prepare the substrate according to the substrate requirements. 2. Cut SANIFIN to the appropriate size. 3. Comb the system adhesive or the bonded waterproof system out to around 10 cm wider than SANIFIN. 4. Insert the strip into the adhesive bed. 5. Press the strip into the adhesive bed using a flat trowel or roller so that there are no voids and no wrinkles. Ensure that the bedding and crosslinking covers the whole area from the fleece to the adhesive. 6. Lay the strips that were cut to size with an overlap of at least 5 cm. Do not glue the overlap area in this case! The strips in the overlap area are only glued once the thin-bed mortar that was used has hardened or cementitious waterproofing using the ASOFLEX-AKB wall PU waterproofing is complete. 7. Alternative, lay the strips that were cut to size end to end without an overlap. The ASO®-Joint-Tape-2000 with the ASOFLEX-AKB wall PU waterproofing is then applied to the middle of the join area after the thin-bed mortar/cementitious waterproofing that was used has hardened. 8. Tiles or boards can be laid in the floor area as soon as the thin-bed mortar or the cementitious waterproofing that was used to lay SANIFIN has hardened sufficiently; this is normally on the next day. Tiling on the walls can be performed on SANIFIN, e.g. with MONOFLEX-XL; MONOFLEXXL can also be used for laying in the floor areas if necessary due to the mechanical and chemical load. The planner must provide the load type and intensity specifications. The Technical Service department at SCHOMBURG GmbH will be happy to assist in these cases.
Application in balconies, terraces, loggias and arcades 1. Prepare the substrate according to the substrate requirements. 2. Cut SANIFIN to the appropriate size. 3. Comb the MONOFLEX-XL or the AQUAFIN®-1K-PREMIUM/-RS300 bonded waterproof systems out to around 10 cm wider than SANIFIN. 4. Insert the strip into the adhesive bed. 5. Press the strip into the adhesive bed using a flat trowel or roller so that there are no voids and no wrinkles. Ensure that the bedding and crosslinking covers the whole area from the fleece to the adhesive. 6. Lay the strips that were cut to size with an overlap of at least 5 cm. Glue the strip in the overlap area to the AQUAFIN®-1K-PREMIUM/-RS300 cementitious waterproofing. 7. Tiles and boards can be laid in the floor area using the floating-buttering method with the MONOFLEX-XL or UNIFIX®-S3 thin-bed mortar as soon as the thin-bed mortar or the cementitious waterproofing that was used to lay SANIFIN has hardened sufficiently; this is normally on the next day. Tiling on the walls can be performed on SANIFIN with MONOFLEX-XL; MONOFLEX-XL can also be used for laying in the floor areas if necessary due to the mechanical and chemical load. The planner must provide the load type and intensity specifications. The Technical Service department at SCHOMBURG GmbH will be happy to assist in these cases.

Technical data sheet SANIFIN Disposal Product leftovers can be disposed of in household waste.
Emission behaviour / building certification systems Very low emissions in accordance with GEV-EMICODE, which normally results in positive evaluations within the scope of building certification systems in accordance with DGNB, LEED, BREEAM, HQE. Maximum quality level 4, lines 9, 35, 44 in accordance with DGNB criteria "ENV 1.2 Risks to the local environment".
Notes Direct contact with metals such as copper, zinc, and aluminium must be avoided by means of a pore sealed primer. A pore-sealed primer is produced via 2 application steps using ASODUR®-GBM (see technical data sheet). Border, field, building separation and movement joints should be carried over to or installed at the designated location; suitable means such as RD-SK50 edging strips should be used to detach them! Crack control joints must be closed with a force fit or secured against height differences, and must be formed as movement joints in the top coating. Observe the technical data sheets of the products mentioned before starting work. Protect surfaces that are not to be treated from the effects of the system adhesive or the bonded waterproof systems! SANIFIN may not be glued or overcoated afterwards with products containing solvents. -
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 Data sheets of the Zentralverband Deutsches Baugewerbe e.V.(German construction Association) in the latest version.
