BITFLEX Anionic Emulsion

The surface must be properly prepared before applying BITFLEX Anionic Emulsion. The substrate intended for product application must be bound, continuous, seasoned, loadbearing, not frozen. If the substrate is contaminated with petroleum-based agents, these must be removed effectively. The surface should be cleaned mechanically, dust, tarnish, any loose pieces and layers, sharp protruding edges and impurities that worsen adhesion should be removed. If there are cavities in the substrate (honeycombing, gravel pockets and other unevenness), it should be repaired, filled and levelled. A suitable levelling mortar should be used to repair cavities. BITFLEX Anionic Emulsion can be used on a dry or slightly damp substrate. A damp substrate prolongs the setting time.

Edges and corners: The exterior right angles should be chamfered (bevelled), while the interior angles should be properly rounded by making facets. On mineral substrates, a facet can be made of mineral mortar e.g. NEXLER RENOBUD R 103 (radius 4 - 5 cm) or PMBC (KMB) compound e.g. BITFLEX 1KP (radius 2 cm). On bituminous substrates make a facet of PMBC (KMB) compound. A cat's tongue trowel is best suited for creating facets.

Check the production date on the packaging before use. The product should not be incorporated beyond its shelf life. The product should not be objectionable (e.g. contain lumps, fibres, discolouration) after opening. After mixing, the product should be homogeneous and free of lumps and clumps. Do not use a product that bears signs of freezing. The correct consistency of the product is not dry or rubbery. When properly mixed and applied, the product does not form a layer on the surface, but penetrates into the substrate.

Substrate priming: Before use, BITFLEX Anionic Emulsion should be diluted with water in proportions depending on the type of substrate.

• Priming of a substrate with regular water absorption: 1 : 1 (water : BITFLEX Anionic Emulsion).
• Priming of a substrate with reduced water absorption: 3 : 1 (water : BITFLEX Anionic Emulsion).

Damp-proof coatings: BITFLEX Anionic Emulsion is a ready-to-use product. Stir thoroughly before use, and repeat mixing from time to time during application.

When fresh, check the consumption of the material per unit and/or dedicated area on an ongoing basis.
A properly primed surface, after the solution has dried, should have a uniform colour, without streaks and discoloration.
Properly made insulation, after drying, should be a uniform, clean coating, without blisters, flakes and other defects, the coating should adhere closely to the primed substrate.

Substrate priming: Apply the diluted product with a brush or roofing brush by rubbing it into the prepared substrate.

Damp-proof coatings: The BITFLEX Anionic Emulsion product can be applied with a brush, roofing brush, roller, spraying device. It is recommended to apply BITFLEX Anionic Emulsion in two working applications. Each operation should take place after the previous layer has dried. The working surface of the created coating must end and start beyond the concave or convex edge, a minimum of 30 cm from the edge.
After binding, the waterproof coating should be protected against mechanical damage associated with backfilling the excavation. Therefore, it is recommended to use additional protection, if not in the form of waterproof thermal insulation boards, then PE, EPDM film or non-woven fabric. Standard dimpled membranes should not be used as a protective and drainage layer to protect bituminous foundation waterproofing, as the dimples may exert local pressure on the coating under soil pressure and damage it. An exception are dimpled membranes with integrated filter fleece.

Before use, please read the application details in the product's Technical Data Sheet.
