WASHPRIMER AQ

What is Epifanes Washprimer AQ and why choose it?

Epifanes Washprimer AQ is a waterborne, solvent-free bonding primer based on acrylic resin. It is designed as an adhesion primer for new aluminium, zinc-coated and galvanized steel, non-ferrous metals, glass and ceramics. The product combines excellent adhesion with a VOC level of 0 g/l, making it suitable for professional and industrial users who require reliable bonding performance with minimal solvent emissions.

With a physical drying mechanism, off-white colour that dries fully transparent and a matt finish, Washprimer AQ prepares the substrate without altering the final colour scheme of subsequent coating systems. It can be used indoors and outdoors, both above and below the waterline, as part of one-component or two-component paint systems specified by Epifanes.

Applications and use cases

Recommended fields of application

• New aluminium surfaces
• Zinc-coated and galvanized steel
• Non-ferrous metals and stainless steel
• Glass and ceramics

The product is intended for use on new, non-corroded metallic and mineral surfaces. For existing surfaces with corrosion, the manufacturer specifies the use of Epifanes Multi Marine Primer as the adhesion primer instead.

Washprimer AQ is suitable for interior and exterior use, including marine applications above and below the waterline, when used within the compatible Epifanes coating systems mentioned in the product information.

Substrate preparation

• General: Do not sand the substrate prior to applying this washprimer.
• New aluminium:
  • Remove all water-soluble salts and other dirt using fresh water and a brush.
  • Remove oil, grease and other contamination with Epifanes Spraythinner for Paint and Varnish.
  • Do not sand the surface.
• Zinc-treated surfaces:
  • Remove all water-soluble salts and other dirt with fresh water.
  • Remove dust and any possible salts with water and a stiff brush.
  • Do not sand the surface.
• Non-ferrous metals / stainless steel:
  • Remove all water-soluble salts and other dirt with fresh water and a brush.
  • Degrease with an appropriate degreaser.
  • Allow the surface to dry completely.
  • Do not sand the surface.

Application recommendations

• Do not apply below 5 °C.
• Avoid excessively high wet film thickness to prevent drying problems.
• Ensure adequate ventilation during application and drying.
• Use only plastic or stainless steel spray nozzles.
• Apply only a thin, even coat and avoid curtain formation.
• Do not sand Epifanes Washprimer AQ after application.

Drying and overcoating

• Dust dry: approx. 2 hours at 20 °C / 65 % RH / 10 µm dry film thickness
• Touch dry: approx. 6 hours under the same conditions
• Recoatable: minimum 2 hours, maximum 14 days at 20 °C / 65 % RH

Recoatability and compatible systems

• One-component systems: Epifanes Multi Marine Primer.
• Two-component systems: Epifanes Epoxy Primer, Epifanes Epoxy HB Coat, Epifanes Poly-urethane Primer.
• Below the waterline: Epifanes Epoxy Primer and Epifanes Epoxy HB Coat.
• Remark on zinc substrates: The combination of alkyd-based primers and paints with zinc may lead to migration of fatty acids and formation of zinc soap, causing loss of adhesion.
