For a reliable, permanent seal according to DIN 18533-3. Can be used in the Würth building sealing system to seal e.g. foundations, intermediate sealing of balconies without underlying structures, and wet rooms. Ideally suited to areas subjected to compressive loads. e.g. underneath floor panels. Due to the product features, it can be used as an insulation panel adhesive. In the case of standing seepage water, you must fully bond the insulation boards. Not suitable for water penetrating from behind or for sealing roofs.
The surface must be dry to slightly moist, and free from grease, oil, frost and tar. Loose components and protruding mortar residues must be removed before commencing work. Apply building waterproofing system primer coat to prepare the surface (art. no. 0893212100). Sharp edges must be blunted and corner and transition areas must be rounded off by means of a chamfer with waterproof mortar (art. no. 0893212110). Compensate recesses > 5 mm with waterproof mortar, art. no. 0893212110.
For proper application, the "Guidelines for planning seals of components in contact with the ground with plastic-modified bitumen-latex thick coatings" and the specifications in DIN 18533 must be observed! The powder (sack enclosed in pail) must be added fully to the liquid components in portions, and vigorously mixed together with a slow-moving agitator, art. no. 0702 836, and mixing paddle, art. no. 071395 137 to produce a pasty, clump-free homogeneous mass. Observe a mixing time of at least three minutes; "two-component bitumen-latex thick coating" must be applied in two layers. Ensure that the first layer has fully hardened before applying the second. Reinforcement fabric (art. no. 0893212105) must be inserted into the surface of the first layer for strengthening. Any levelling compounds are not valid as seals; the specified minimum layer thickness must be maintained across the entire surface and must not be exceeded by 100%. On adjacent components (floor panels or similar structures) to at least 15 cm of the front. A horizontal seal must be incorporated into the surface seal in all areas.
The minimum processing temperature is +5°C. It is essential that the effects of rain and frost and water stress are prevented until both coats have completely dried. Direct sunlight should be avoided. Ideally, surfaces not to be coated (e.g. in an area to be subsequently plastered) should be covered, as the bitumen compound cannot be removed without leaving residue. During application, it is recommended that you wear personal protective equipment (safety goggles, art. no. 0892 102 ff. / gloves art. no. 0899 435 ff.). The second component contains cement; therefore avoid contact with skin.
The second component (powder) contains cement. Avoid contact with skin.
