MORCEM ELASTIC PM is a single component liquid polyurethane resin, with an optional accelerator. Cures forming a flexible elastomeric membrane, hard and weather resistant, and which has waterproofing properties.


Features and applications

  • Applied cold with a brush, roller or spray gun.
  • Resistant to weather, ultraviolet radiation and frost.
  • Permeable to vapour (unlike bituminous or PVC coatings).
  • Excellent extension: greater than 900%.
  • Resistant to microorganisms.
  • Can be used to bridge cracks if applied with the minimum required thickness.
  • Excellent resistance to wear, abrasion and perforation.
  • Resistant to salt water, sewage, petroleum, oils, acid rain and mildly acidic liquids.
  • It can be used on wet concrete, masonry, steel, wood and other surfaces.
  • Waterproofing roofs, insulating foam and rock wool panels.
  • Waterproofing balconies and terraces.
  • Waterproofing of tanks, channels, plasterboards…
  • Waterproofing flower beds and garden areas.
  • Waterproofing concrete construction like bridges, tunnels, etc.


  • The support must be sound, clean, and free of grease, oils, dust and poorly adhered parts that would make adherence difficult.
  • The support must be structurally solid.
  • Cleaning with high pressure water is not recommended due to the residual moisture of this treatment. Treat surface with a sand blast.
  • Cracks and damaged concrete have to be repaired beforehand with MORCEMREST R-15.

Instructions for use

Mixing the mortar:

  • Mix and remove MORCEM ELASTIC PM manually or in a low revolution electric mixer (less than 300 rpm). For cold temperature applications, and for faster curing times, use a 2-4% accelerator.


  • Apply with a roller, brush or spray equipment without air.  The nozzle of the spray equipment should be 5/33″. Filters and suction hoses are not needed. All hoses should be 3/8″ diameter. A conventional 60/1 spray gun is recommended.
  • Application of IMPLAREST EP primer is always recommended to neutralize porosity and moisture of the support.
  • Apply 2/3 layers of product with a total maximum thickness of 2 mm. Apply the second layer after 12 to 24 hours since the application of the first layer, once it is completely dry. In case of using a set accelerator, wait 3 to 4 hours.
  • For compound curves on corners, wall/floor joints and other details, it is recommeded that a strip of Reinforcing Mesh be applied to reinforce the joint.

Curing process:

  • MORCEM ELASTIC PM is rainproof in 4 hours from application.
  • Suitable for light pedestrian traffic in 24 hours from installation.
  • Protect from wind, freezing temperatures and sun during application and hardening.
  • If the cured membrane will be used for contact with potable water, the surface must be thoroughly cleaned to ensure that all the solvents have been entirely eliminated.

Cautions and recommendations

  • Do not apply below 5ºC nor above 30ºC.
  • MORCEM ELASTIC PM should only be applied when the temperature is constant or decreasing.
  • Never apply in layers more than 0.6 mm thick (dry thickness).
  • Tools should be cleaned with solvent immediately after use to prevent the material from hardening.
  • Prevent dew-point temperatures during the first hours after application.


MORCEM ELASTIC PM is sold in 6 kg and 25 kg metal containers.Accelerator sold in 0.24 kg and 1 kg cans.Shelf life: 9 months in sealed original packaging, sheltered from weather conditions and humidity.
