Desmoplus 1 layer


Additive for the desmopol application in one coat

Additive that gives to the single-component polyurethane membrane Desmopol several properties to facilitate its application in one layer without bubbles inside, improve its physical and mechanical properties, and give a fast dry time. It is suitable for the application of polyurethane membranes in low-temperature conditions or adverse weather conditions.s.


For application in the following situations:

  • Allows the application of the Desmopol membrane polyurethane liquid membrane in one coat of desired thickness (e.g. 2 mm./78 mils DFT), avoiding the application by successive coats, eliminating intermediate drying times, and dangers due to sudden rain
  • Internal blistering elimination.

NOTE: NOTE: call our technical department about the application to other substrates or scopes of use

  • It allows the application of Desmopol in aone thick layer, saving execution time since it eliminates intermediate processes.
  • Eliminates the formation of internal bubbles and other defects in the curing of the membrane, it improves the quality of the Desmopol membrane
  • Reduces drying and curing times on polyurethane membrane Desmopol especially in winter, cold weather, low humidity.
  • Increases the mechanical properties of the polyurethane membrane Desmopol
  • Use Desmosolvent for the cleaning.
  • Do not use any kind of spray machine, to apply polyurethane membrane Desmopol  when mixed with Desmoplus


The mandatory consumption is fixed and invariable depending on the Desmopol format to be used:

  •  2l. (1,7 kg) of each 25 kg. of Desmopol
  • 1,2l (1 kg).  of each 15 kg. of Desmopol
  •  0,5 l. (0,43 kg) of each 6 kg. of Desmopol

NOTE: these consumptions are invariable and fixed, they cannot be varied, neither by excess nor by defect, otherwise the membrane will not form in the adequate conditions of use. During mixing, use mechanical equipment at half revolutions to avoid the inclusion of air inside.


Metal tins in three different formats:

  • 2 l (1,7 kg)
  • 1,2l (1 kg)
  • 0,5 l (0,430 kg)


12 months at temperatures between 5° C and 35° C (41 ºF to 95 ºF), provided it is stored in a dry place. Once the tin has been opened, the product must be used.


You should consider the following factors:

  • One metal tin of 2l. (1.7 kg) is the needed amount required for optimal response, making the mixture with 25 kg of Desmopol
  • One metal tin of 1,2l.(1 kg) is the needed amount required for optimal response, making the mixture with 15 kg of Desmopol
  • One metal tin of 0,5l. (0,430 kg) is the needed amount required for optimal response, making the mixture with 6 kg of Desmopol
  • Shake Desmoplus layer, before the mixing procedure
  • Incorporate Desmolplus into the polyurethane membrane Desmopol metal tin, wait for 3-4 minutes, and homogenize with an electric/mechanical mixer to avoid air entrainment and wait for 3-4 minutes. Check on the Desmopol TDS the point "APPLICATION TYPOLOGIES", section "Single coat application (mixing Desmoplus).
  • The pot life is around 90 minutes.
  • Pour the material on the surface, sharing with a notched trowel to get the desired thickness (You can also do this with roll or rubber lip)
  • The drying time is between 1 and 3 hours. (Results have been performed in the laboratory at 23ºC and 50% RH, under controllable conditions. These values may vary depending on the application, climatology, or substrate conditions).
  • On high ambient temperatures situation, open the DESMOPOL drums, proceed with a low-speed agitation to stir resin to try to refresh the temperature, in order to don't increase the chemical speed reaction and therefore maintain the time of ".pot life "


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 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 of the product (MSDS), or contact our technical department.
