DESMOPOL T

Single component, transparent and aliphatic polyurethane waterproofing membrane

DESMOPOL T is a single component high solid, transparent and aliphatic polyurethane resin, which once made forms a continuous, elastic, without any joints or overlapping, and totally waterproof.

It is applied manually, using a roller or brush.

dilution 5% DESMOSOLVENT ("airless" equipment)
application method by brush, roll, or "airless" equipment

GENERAL FEATURES

  • DESMOPOL T is a highly elastic and wear-resistant membrane that, once applied, offers great stability and durability.
  • DESMOPOL T adapts to any surface, making it the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.
  • Applying DESMOPOL T saves in seals and any other kind of joins, as the finish is uniform and makes up a single layer, providing a surface with optimum maintenance and cleaning properties.
  • It should be applied in dry conditions avoiding the presence of humidity or water coming from the surface to be coated or the substrate, whether at the time of application or subsequently (pressure from phreatic water level).
  • It doesn’t require solar radiation protection (UV rays) to ensure its properties, because it is an aliphatic membrane.
  • DESMOPOL T system's properties enable it to bond several kinds of surfaces such as natural stone, ceramic. For another kind of support, please, contact with TECNOPOL technical department.
  • High resistance all over the time, retaining its transparency.
  • Use PRIMER T primer before application of membrane.
  • Not recommended to use in pools, or chemically treated water, in general not use on total water immersion.
  • Once formed, don’t clean with bleach or highly corrosive products.
  • Do not apply DESMOPOL T media with temperatures above +35 ° C
  • If there is humidity or moisture in the substrate at the time of application, check the technical specifications of our primers where the maximum support humidity ranges are specified.

YIELD

Product yield is 0.5 to 1 kg/m², applied in 2 layers, depending on the application method and conditions.

PACKAGING

Metal tins of 20 kg and 5 kg

SHELF LIVE

12 months at temperatures between 5° C and 35° C, provided it is stored in a dry place. Once the tin has been opened, the product must be used immediately.

APPLICATION

In general, the following aspects should be dealt with prior to application:

  • Support will be strong and dry.
  • Clean up the surface, removing dust, oils and grasses,  and existing chippings.
  • We recommend applying on the substrate with the primer PRIMER T with a clean cloth and allow drying (15 - 20 min).
  • Can be applied by roller, brush or "airless" spray.

HANDLING

These safety recommendations for handling are necessary for the implementation process as well as in the pre and post, on exposure to the loading machinery.

  • Respiratory Protection: When handling or spraying use an air-purifying respirator.
  • Skin protection: Use rubber gloves, remove immediately after contamination. Wear clean body-covering. Wash thoroughly with soap and water after work and before eating, drinking or smoking.
  • Eye / Face: Wear safety goggles to prevent splashing and exposure to particles in the air.
  • Waste: Waste generation should be avoided or minimized. Incinerate under controlled conditions in accordance with local laws and national regulations.

Anyway, consult the material and safety data sheet (MSDS) of the product
