GENERAL FEATURES

  • DESMOPOL is a highly elastic and wear-resistant, aromatic, moisture-cured, solvent-content liquid polyurethane that once applied, forms a continuous, seamless, waterproofing, and solid membrane.
  • it holds an ETA 10/0121, issued by EOTA (European Organization for Technical Assessment). under the 005 guide, specific approval for "Liquid Applied Roof Waterproofing based on polyurethane" working life 25 years ( W3), at 1.2 mm thickness, ponding water admitted
  • it holds a BBA certification n 16/5340 (validation on UK market  and influenced) for waterproofing of walkable roofs,  at 1,2 mm thickness, ponding water admitted
  • Thanks to its versatility Desmopol adapts to any surface, making it the ideal product for application on uneven surfaces and in areas of any shape, whether curved or squared.
  • No surface reinforcement is required, only detail works encounters with other building elements.
  • Green roof application certified, according to EN 13948( on ETA 10/0121 and BBA 16/5340)
  • Desmopol, polyurethane liquid membrane can be applied in only a single layer (minimum total thickness recommended 1,5 mm) by mixing with Desmoplus or Desmoplus 700, this fact upgrades their physical performances, increases the execution speed, and thus reduces the direct costs of the application, forms a solid membrane without bubbles inside. Using Desmoplus or Desmoplus 700, do not use an airless machine.
  • it should be applied in dry conditions avoiding the presence of humidity or coming from the surface to be coated or the substrate, whether at the time of application or subsequently (pressure from phreatic water level). In the event there is humidity in the substrate at the time of application, consult the technical specifications of our primers in the TDS
  • the system requires solar radiation protection (UV rays) to do not lose its physical and mechanical properties, given that it is an aromatic membrane. Therefore, our EOTA (European Organization for Technical Assessment) approved systems (ETA 10/0121, BBA 16/5340), incorporates a protective polyurethane colored aliphatic resin, Tecnotop 2C, for use in the absence of other physical protection elements. You can apply too Tecnotop S-3000, Tecnotop 2CP or Tecnotop 1C.
  • Desmopol system's properties enable it to bond to any surface, such as cement, concrete, polyurethane foam, butyl, and bituminous sheets of wood, polyurethane plates, metal, etc.
  • Due to its resistance, it can be walked on and it will accept a rough finish to make it non-slip. (using Silica Sand or Tecnoplastic range)
  • Desmopol polyurethane liquid membrane is a self-leveling membrane. It can be used on low and steep slope roofs. It requires a Desmothix additive for slopes of more than 1,5% of a gradient. Mix Desmothix, maximum ratio 1liter for each 25 kg of Desmopol. You could apply on thin several layers.

 

  • Do not use airless equipment when you apply with Desmothix or Desmoplus/Desmoplus 700
  • Ceramic flooring can be placed on top. In this case, we recommended spreading a well-distributed load of Silica Sand to improve mechanical anchorage in the last layer of Desmopol, or if it has already catalyzed, spreading a layer of 50 to 60 g/sqm PRIMER PU-1000, for anchoring the Silica Sand
  • It can be used to fill fissures and joints, using Desmoplus/Desmoplus 700 (see TDS of booth products)
  • Consult our technical department, the Technical Guides of systems or the Application Methodologies, the characteristics of the proposed system according to the use, situation, or type of application.

APPLICATION TYPOLOGIES

Once the surface preparation and primer application are done, as conditions, proceed to apply the polyurethane membrane, using the following methods:

1.-Application by coats (traditional or classical application )

  • Open the DESMOPOL metal tin and stir it up to homogenize
  • Extended the first layer using a short nap roller, a maximum thickness of 0,7 mm. ( 1,2 kg/sqm). Applying the material without dilution.
  • Wait for complete drying (depend on the weather conditions), about 5~6 hours
  • Then, apply the next layer, in the same way as above
  • Repeat this process as many times as necessary to achieve the desired or recommended thickness.

2.-Application by coats with intermediate reinforcing (using TECNOMESH 100)

To be used in ceramic supports, torch and felt, bitumen membranes  in general, in cracked supports, or that have contraction or dilation movements

  • Open the DESMOPOL metal tin and stir it up to homogenize
  • Extended the first layer using a short nap roller, a maximum thickness of 0,7 mm. ( 1,2 kg/sqm). Applying the material without dilution.
  • Extent TECNOMESH 100 on the wet resin, and push using a dry roll
  • apply DESMOPOL on the still-wet previous coat.

In this case, consumption can increase from the application without mesh.

3.-Single coat application (mixing DESMOPLUS or DESMOPLUS 700)

  • Pour DESMOPLUS inside the DESMOPOL metal tin, always in the fixed ratio supplied by the manufacturer. Continuous mixing with medium-speed mechanical equipment
  • Pouring of the material formed directly on the support, and spread using Use of trowel, squeegee or rubber lip (a short nap roll can also be used).
  • This process is unique, whereby the desired thickness is obtained in one operation, eliminating intermediate waiting times, ensuring the formation of the membrane without internal bubbles, getting more tensile strength, and reducing the global drying time.
  • The use of a mechanical equipment mix it’s not recommended when DESMOPLUS is used.
  • if it is necessary to add DESMOTHIX due to the slope of the roof, you can add a maximum of 250 ml of this ( per 25 kg DESMOPOL pail ). 
  • Check all the waiting and drying times, application conditions (see the TDS)

4.-Mechanical application ("airless" equipment)

  • Add 5~10% solvent DESMOSOLVENT into DESMOPOL metal tin. Mix the drum with medium-speed mechanical equipment.
  • Apply thin layers using specific equipment.
  • Wait for total drying.
  • Repeat this process until the desired or recommended thickness.

Notes:

  • Consult in all cases the waiting times, drying time, singular points treatment, conditions of applying all the products through the technical data sheets of each product, the technical guidelines, or consulting our technical department.
  • For other types of supports/substrates, for further information on the execution application procedure, for any additional questions, please, consult the technical data sheets (TDS) of these products, or our technical department.

REPAIR AND OVERLAPS PROCESSES

REPAIR
Desmopol has very good adhesion on the substrates. To improve it In cases where the membrane must be repaired by accidental causes, or assembly procedures not covered installations, shall be as follows:

  • cut, removal of the affected area and/or damaged surface
  • sanding this area extending about 20~30 cm. around the perimeter, for overlapping security
  • cleaning (vacuuming) of waste generated (powder, dust...); if it's possible don't use water, and if used, support humidity value; ketones applicability based solvents for reducing this type of surface cleaning
  • apply a thin layer (100-150 g/sqm) of polyurethane resin PRIMER PU-1050, PRIMER EPw-1070
  • light spread SILICA SAND over the wet primer applied before
  • wait for the total drying
  • apply  DESMOPOL (with DESMOPLUS or DESMOPLUS 700), TECNOCOAT CP-2049, TECNOCOAT CP-2049 PLUS
  • apply TECNOTOP S-3000/2C/2CP/1C, in consumption and desired thicknesses in the case of no protection against UV rays. This application can be done by short nap roller type equipment "airless" (see the conditions of application in the product datasheet TDS)

OVERLAPS
In cases has been exceeded recoat time (24~48 hours), so the waiting time between jobs is prolonged, proceed as follows:

  • sanding strip longitudinal overlap of about 20~30 cm. wide
  • cleaning (vacuuming) of waste generated (powder, dust...)or existing dust; if it's possible, do not use water, and if it's used, check the support humidity value; ketones applicability based solvents for conducting this type of surface cleaning
  • apply a thin layer (100-150 g/sqm) of polyurethane resin PRIMER PU-1050, PRIMER EPw-1070.
  • light spread SILICA SAND over the wet primer applied before
