AQUAFIN-RB400 can be used to renovate old, firmly adhering coatings containing bitumen (not bitumen sheeting). The waterproofing must be covered with a scratch coat and double-coated after drying out completely. The base point area and the transition to the splashing water base must be stripped down to the cementitious substrate beforehand, because these connection and termination areas are frequently affected by moisture penetration from the rear during renovation.

Corners and edges such as those on base slabs, etc. must be cut or chamfered. Depressions > 5 mm and damaged areas, large-pored substrates, or uneven masonry must be levelled out beforehand using a suitable cement-based mortar, e.g. ASOCRET-M30. Alternatively, levelling or filling coats < 5 mm can be applied with a mixture of AQUAFIN-RB400/quartz sand 0.1–0.35 mm (approx. 5 kg on 20 kg of AQUAFIN-RB400). The substrate must be pre-dampened so that it is matt damp when AQUAFIN-RB400 is applied. Extremely absorbent and slightly sandy substrates must be primed with ASO-Unigrund-GE or ASO-Unigrund-K, and the primer must be totally dry before the subsequent work steps are carried out.
Possible additional consumption in case of uneven substrates and artisanal variations must be considered.
Moisture penetration from the rear and intermittent moisture loading from the negative side must be avoided. We recommend pre-sealing with AQUAFIN-1K to prevent pushing off of the substrate. This requires min. 1.75 kg/m² AQUAFIN-1K. On uneven substrates, pre-sealing with ASOCRET-M30 can also be completed with consumption of 1.4 kg/m²/mm. Negative moisture
Substrate: The substrate must be load-bearing, fully grouted and level to a large extent, open-pored, and have a closed surface. It must be free of gravel pockets, cavities, gaping cracks and ridges, dust and adhesion inhibiting

loading can also be counteracted with ASODUR-SG2/-thix depending on the object. Consumption of 600–1,000 g/m² is required when using ASODUR-SG2/-thix.
systems like HighPump M8 (peristaltic pump), HighPump Small, -Medium or -Pictor (screw pump), we recommend a nozzle size of 4.5 to 6.0 mm. For more information, contact Dittmann Sanierungstechnik GmbH, Hohen Neuendorf, www. saniertechnik.de.
Application: Put approx. 50–60% of the liquid component into a clean mixing bucket and mix with the powder component to produce a homogeneous, lump-free compound. Finally, add the rest of the liquid component and mix sufficiently. A mixing time of approx. 2–3 min. is required with a powerful agitator (approx. 500–700 min-1). After a settling period of approx. 2 minutes, thoroughly homogenise the compound again.
For watertight formation of moving and connecting joints, use the system components of the ASO-joint tape method in accordance with the respective wear class. Apply ASO-Dichtband-2000-S, or ADF-Dehnfugenband in the transition between the wall and floor and across connecting joints, and adhere ASO-Dichtband-2000-S-Ecken joint tape in the corner areas with AQUAFIN-RB400. Apply AQUAFIN-RB400 at least 2 cm wider than the width of joint tape you use. The joint tape is placed in the fresh layer and then pressed in without voids or wrinkles. Bonding must be carried out in such a way that water cannot migrate around the back. The joint tape to be used should be inserted in a loop over movement joints. The joint tape edges must be adhered overlapping at least 5 to 10 cm with AQUAFIN-RB400, free of wrinkles and covering the whole area. Finally, the bonded joint tapes must be coated over with AQUAFIN-RB400 and seamlessly integrated into the waterproofing. Proceed in the same way when inserting ASO joint tape pre-formed pieces.
Due to the project or processing conditions, e.g. processing using the screening or spraying method, adding water up to a maximum of 1.0% (0.2 l/20 kg) AQUAFIN-RB400 is permitted. Water is added after mixing the powder and liquid component. Pre-screen the base slab-wall transition with AQUAFIN-1K or ASOCRET-M30 featuring consistency able to be screened, and install a sealing groove of ASOCRET-M30 with an edge height of at least 4 cm while it is still wet. After drying, carry out the waterproofing with AQUAFIN-RB400.
Pipe penetrations: Depending on the nominal diameter, the ASO-Dichtmanschette-Boden (ASO sealing sleeve base) or ASO-Dichtmanschette-Wand (ASO sealing sleeve wall) or ADF-Rohrmanschette (ADF pipe sleeve) are used for waterproofing pipe penetrations with non-pressing water and waterproofing is applied at least 5 cm onto the pipe penetration. In case of pressing water, use suitable loose fixed flange constructions. Apply the AQUAFIN-RB400 generously to the thin-bed flange and overlapping area, embed the sealing sleeve used free of voids and wrinkles and subsequently integrate in the waterproofing by means of complete over-coating.
AQUAFIN-RB400 is applied pore-free by trowelling, spraying or brushing for at least two application steps. The second and subsequent application steps may be completed once the first application step cannot be damaged (approx. 3 hrs., depending on the ambient conditions). An even layer thickness is achieved, e.g. using a coating thickness trowel or a 6 to 8 mm notched trowel and then smoothing. Apply as much material as needed to achieve the required dry film thickness. If you apply using the spraying method with suitable spraying

Drainage and protection boards for components in direct ground: The waterproofing must be protected against weathering influences and mechanical damage using suitable protective measures. Protective layers may only applied after drying is complete. Suitable protection and drainage boards can be fastened using heaps of COMBIDIC-1K, and the perimeter insulation must be bonded covering the whole area and butt jointed with COMBIDIC-2K-CLASSIC or COMBIDIC-2K-PREMIUM. Alternatively, protective layers can be bonded covering the whole area with a mixture of AQUAFIN-RB400/ quartz sand 0.1–0.35 mm (approx. 5 kg on 20 kg AQUAFIN-RB400) and suitable notched trowel using the Buttering-Floating method.
paints). Silicon resin paints and acrylate-based paints may also be used. • Direct contact with metals like copper, zinc, and aluminium must be avoided by means of poresealed priming. Pore-sealed priming is produced via 2 application steps using ASODUR-GBM. The first application step is generously applied to the degreased and cleaned substrate. Once this coat has reacted to the extent that it can no longer be scattered (approx. 3–6 hours), another coat of ASODUR-GBM is brushed on and sprinkled with quartz sand featuring a grain size of 0.2–0.7 mm. Consumption of ASODUR-GBM approx. 800–1,000 g/m². • To waterproof PVC, gunmetal, and stainless steel flanges, abrade, clean, and degrease the flange, apply AQUAFIN-RB400 and ASO-Dichtmanschette (ASO-Joint-Sleeve) or alternatively embed the ADF-Rohrmanschette (ADF-Pipe-Sleeve) without cavities or wrinkles and connect seamlessly to the surface waterproofing.
Drainage is implemented in accordance with national regulations. Notes: • Protect surfaces that are not to be treated against the effects of AQUAFIN-RB400! • The waterproofing must not be affected by water while it is setting. The effect of water from behind can lead to spalling in case of frost. • In case of strong sunlight, work against the movement of the sun in shaded areas. • In rooms with high humidity and/or insufficient ventilation (e.g. water containers), dew point undershooting (condensation formation) may occur on the surface. This must be avoided by taking suitable measures, e.g. by using condensation dryers. Direct heating or uncontrolled blowing warm air is not permitted. • AQUAFIN-RB400 may not be subjected to punctuated or linear loads as the surface coating. • AQUAFIN-RB400 may be plastered and coated with vapour permeable, solvent-free dispersion facade paints or dispersion silicate paints (not pure silicate
