Prepare penetrations with a thin-bed flange to a minimum width of 5 cm circumference around the flange composed of a suitable material for bonding such as e.g. stainless steel, red brass, PVC-U. Clean and degrease the flange. With narrower flange widths (> 30 mm, < 50 mm), we recommend bonding the waterproof gasket – at the flange transition – with ASOFLEX-AKB-Wall.
Product preparation: Place approx. 50–60 % of the liquid component into a clean mixing bucket and pre-mix with the powder component to create a homogenous, lump-free mass. Then, add the remaining liquid component and adequately blend. With a mechanical mixer (approx. 500–700 rpm), a mix time of approx. 2–3 mins is required. Allow to stand for approx. 5 minutes, thoroughly homogenize by mixing once again. Mixing AQUAFIN-2K/M-PLUS is carried out with the following mix ratio, parts by weight: 2.5 parts powder component : 1 part dispersion component. AQUAFIN-2K/M-PLUS is applied, free from pores, by brush or trowel in at least two coats. The second, as well
Eliminate moisture penetration from the rear and localised moisture from the negative side. In all cases where there is rear moisture penetration, we recommend prewaterproofing with AQUAFIN-1K, to prevent negative pressure from the substrate. Dependent on the water pressure, carry out single or multiple coatings beforehand. For ground moisture the consumption is min. 1.75 kg/ m² and water pressure min. 3.5 kg/m² AQUAFIN-1K. In concrete constructions, moisture pressure from the negative

Alternatively, AQUAFIN-2K/M-PLUS can also be spray applied with suitable spraying equipment such as e.g. HighPump M8 (Peristaltic pump), HighPump Small or HighPump Pictor (screw feed pump). Information can be obtained from HTG HIGH TECH Germany GmbH, Berlin, www.hightechspray.de. When spray applying, adding a max. of 1.5% water (0.5 l / 35 kg) AQUAFIN-2K/M-PLUS is permissible, depending on the equipment. To form water resistant expansions and construction joints, incorporate the ASO-Joint-Tape technology system components appropriate to the particular water exposure class. Using AQUAFIN-2K/M-PLUS, bond ASO-Joint-Tape-2000/-S or ASO-Joint-Tape-2000/-S-Corners (internal and external corner pieces) in the corner areas, at the transition between wall and floor as well as over connection joints. Using a 4–6 mm notched trowel, apply AQUAFIN-2K/M-PLUS to both sides of the joint that is to be bridged. AQUAFIN-2K/M-PLUS has to be at least 2 cm wider than the joint tape to be used. Lay the joint tape into the wet layer and then carefully press in without folds or voids. Bonding must be carried out in such as way as to eliminate the possibility of water migration around the back. The joint tape should be laid in a loop over expansion joints. Waterproof tape joints should be overlapped by a minimum of 5 to 10 cm and bonded with AQUAFIN-2K/M-PLUS without folds or voids. Subsequently overcoat the bonded joint tapes with AQUAFIN-2K/M-PLUS and seamlessly integrate into the main waterproofed areas. Follow the same procedure when installing ASO-Joint-Tape pre-formed pieces.
as subsequent coats may only be applied on the first coat can not become damaged by foot traffic or by further coating applications (approx. 3–6 hrs, depending on ambient conditions). A consistent thickness, dependent on exposure conditions, is achieved e.g. by a 4 to 6 mm notched trowel and subsequently smoothing. Use as much material as required to achieve the dry film thickness necessary for the water exposure class. An application thickness of more than 2.2 kg/m2 in a single coat can

diameter and waterproof to a minimum of 5 cm at the pipe penetration. When using suitable flange units, apply AQUAFIN-2K/M-PLUS to saturation on the thin-bed flange and the overlap area. Bed the ASO-Dichtmanschette into the wet coat without folds or voids and then fully integrate into the surrounding waterproofing by overcoating.
• Protect areas that are not to be treated with AQUAFIN-2K/M-PLUS! • During the curing process, do not expose the waterproofing to water. Water penatrating from the rear can lead to de-bonding in frost. • In case of strong sunshine, work against the direction of the sun in the shade. • In rooms with high humidity and / or inadequate ventilation (e.g. water containers), the surface may drop below the dew point (condensatio). This can be prevented by using suitable measures such as e.g. dehumidifiers. Direct heat or uncontrolled blown warm air is not reliable. • As a surface waterproofing, AQUAFIN-2K/M-PLUS may not be subjected to point or linear loading. • AQUAFIN-2K/M-PLUS can be rendered and also coated with vapour permeable, solvent free dispersionbased facade or silicate paints (do not use pure silicate paints). Silicone resin or acrylate-based paints can also be used. • Direct contact with metals such as copper, zinc and aluminium is to be prevented by a porous-free priming coat, produced with two coats of ASODUR-GBM. Apply the first coat to saturation to the degreased and cleaned substrate. Once this coat has reacted to a point where it will no longer accept a broadcasting sand (approx. 3–6 hrs.), apply a second coat of ASODUR-GBM and broadcast with 0.2–0.7 mm quartz sand. Consumption approx. 800-1000 g/m² ASODUR-GBM. • To seal PVC, red brass and stainless steel flanges, abrade the flange, clean degrease, apply AQUAFIN-2K/M-PLUS and ASO-Dichtmanschette or alternatively the ADF-Rohrmanschette bedded without voids or folds and seamlessly connect with the surrounding waterproof membrane.
Drainage and protective boards with building elements in contact with the soil: Waterproofing are protected against weathering and mechanical damage using suitable protective measures. Only install protective layers once the waterproofing has fully dried. Protective and drainage boards can be fixed on dabs of COMBIDIC-1K but insulation boards is to be fully bonded with COMBIDIC-2K-CLASSIC or COMBIDIC-2K-PREMIUM and tightly butt jointed. Waterproofing in combination with tiles and slabs: Floor drains and penetrations in pool areas must be provided with suitable flange elements. Apply AQUAFIN-2K/M-PLUS to saturation on the thin-bed flange and overlap area. Bed the ASO-Dichtmanschette-Boden into the wet waterproofing without voids or folds so that a watertight connection is produced with the surrounding waterproofing. To seal pipe penetrations in walls, ASO-Dichtmanschette-Boden or ASO-DichtmanschetteWand appropriate for the nominal diameter can be used. Roughen the pipe penetration, clean and degrease with a suitable material and prime as necessary. Apply on AQUAFIN-2K/M-PLUS to saturation and install the ASO-Dichtmanschette. Always overlap the joint tapes on to the surrounding waterproof membrane. Jointing is always carried out with a 5 cm to 10 cm overlap. Installation of tiles or slabs is carried out with one of the tile adhesives named under system components. At the time of tile installation, the waterproofing coat must be fully hardened.
