Primer EP


Two-component epoxy resin as a primer

Two-component, 100% solids content epoxy resin. It is specially designed to increase adhesion to substrates and improve planimetry for liquid waterproofing systems TECNOCOAT and DESMOPOL and flooring systems TECNOTOP and TECNOFLOOR.

TDS. Technical Data sheet(PDF)


For application in the following situations:

  • increase adhesion on metal surfaces and ceramic tiles (smooth finishing)

NOTE: call our technical department about the application to other supports or situations

density 1,05± 0,1 g/cm³
viscosity 1.000±200 cps
pot-life ± 40 minutes
initial drying  time 4~6 hours
application method by short nap acrylic wool roller or“airless” equipment


  • Two-component, 100% solids content epoxy resin, solvent-free, odorless, which once dry forms a continuous film in steel or ceramic substrates increasing adherence for liquid waterproofing and flooring systems
  • Its consumption depends on the situation of the substrate, irregularities that it presents or level of planimetry.
  • Do not use with groundwater pressure (water pressure coming from the back of the treated element)
  • No dilution needed at all


Metallic kit pails: 8 kg.+5kg.


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.


The following factors prior to application should be checked:

  • previous preparation of the substrate according to its type
  • existing holes or areas with a lack of material must be repaired using some or our epoxy resins: Primer EP-1020/Primer EP-1010
  • joint fillings with Mastic PU
  • in existing dilatations joints: remove old material, clean, and fill with Mastic PU. Use also Tecnoband 100 to cover, if necessary.
  • general cleaning of the substrate, removing existing dust, dirt, grease or efflorescence. The substrates must be resistant and cohesive.

Steel and ceramic substrate

  • check the maximum degree of moisture permittivity of the substrate
  • mix the two components using a mechanical shaker for approximately 4-5 minutes (medium speed)
  • apply the resin in two or more thin crossed coats until the desired planimetry is achieved. (always wait for drying before recoat). Consumption between 150 and 200 g/sqm depending on the roughness of the support. Apply as many coats as the substrate needs. Always respect the recoat time between coats or between different materials. In case of rain, apply a thin layer, consumption approx. 100-150g/sqm.

NOTE: For other types of substrates, weather conditions or final use, consult our technical department.


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 of the product(MSDS) or contact our technical department
