Single-component, cold-applied, seamless, elastic, moisture-reactive, easily applied, polyurethane liquid membrane used for waterproofing.

Instruction for Use

  • Application method: Apply DANOPUR® BALCONIES by roller or airless, in one or two coats. 3-5 hours drying time between each coat (no more than 6 hours). For a correct result, the temperature during application and curing should be between 5 and 35oC. Humidity may affect the final result.
  • Total consumption:
Waterproofing: 1.3 to 2.5 kg/m2 applied in two or three coats.Tools: Roller, brush, rubber trowel or airless spraying equipment.Checking environmental conditions: Ambient/substrate temperature between 5 to 35ºC. Relative humidity < 80%. Waterproofing work must not be carried out when weather conditions may be detrimental (when it is snowing or there is snow or ice on the roof; when it is raining or the roof is wet).Product preparation: Stir for at least 1 minute with a mechanical stirrer until homogeneous mixture is obtained.
Membrane application: A coat of DANOPRIMER® primer must be applied according to the type of substrate to promote adhesion of the membrane. Respecting the curing times of the primer, apply three coats of DANOPUR® PT. Always reinforce the singular points, such as vertical and horizontal wall junctions, areas where the substrate changes, junctions with drains, etc. It is recommended to reinforce the entire surface with PET50 polyester reinforcement (the overlap of this reinforcement should be between 5 and 10 cm) and leave it to soak into the first layer, still in a damp state, and then apply the PET50 reinforcement (the overlap of this reinforcement should be between 5 and 10 cm). After a minimum of 12 hours and a maximum of 48 hours apply the second coat of DANOPUR® PT and for more demanding end-use roofs apply a third coat of DANOPUR® PT. Do not apply coats thicker than 0.6 mm. If a colourfast finish is desired, apply one or two coats of DANOPUR® LT over the DANOPUR® PT membrane. DANOPUR® PT is slippery when wet. To avoid this, it is recommended to sprinkle DANOQUARTZ SP49 silica aggregate on the last coat of the system to achieve a slip resistant surface. DANOPUR® PT is not recommended for use in direct contact with treated or chlorinated water.

Cleaning of Work Tools
