Primer EP

PRIMER EPw-1070

Two-component epoxy resin as a primer

Two-component, water-based 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.



Uses

GENERAL SPECIFICATIONS

  • Two-component epoxy water-based resin, solvent-free, odorless, which once dry forms a continuous film in mortar, concrete, bitumen felts, ceramic tiles, and steel 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. It can be applied in a thick layer, self-leveling system
  • Do not use with groundwater pressure (water pressure coming from the back of the treated element.
  • It can be diluted in water (max. 20%), to facilitate application. It must be valued the humidity existing on the substrates.
  • It holds a CE marking on the basis of a statement made DoP Declaration of Performance (DoP) under the EN-1504-2:2004 table 5

PACKAGING

Metallic pails in two different formats:

  • LARGE KIT:15 kg+5 kg
  • SMALL KIT: 3 kg+1 kg

SHELF LIFE

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

APPLICATION METHOD

The following factors prior to application should be checked:

  • previous preparations of the substrate through physical processes (substrate preparation (sanding, polishing, shot blasting, or milling) for laitance and reliease agents as well as for the opening of the surface pore, achieving a suitable anchorage profile. (CSP 3 -4-5, according to the ICRI)
  • 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.
  • joint filling for installation, work and consolidation of surfaces.
  • general cleaning of the substrate, removing existing dust, dirt, grease or efflorescence. The substrates must be resistant and cohesive.

Mortar, concrete or ceramic substrate

  • substrate must be fully cured (the concrete curing process is 28 days). Check the maximum degree of moisture permittivity of the substrate
  • dilute with water (max- 20%), on non-porous substrates for a thin film, or to facilitate the application in the case of rough substrates.
  • 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 substrates. Apply as many coats as the substrate needs.

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

HANDLING AND SAFETY

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.
