AndCoat Prime

Andcoat Prime – High-Performance Epoxy Primer for Concrete

AndCoat Prime is a high-performance, translucent primer formulated for concrete and other cementitious surfaces prior to applying epoxy resin coatings from the Andcoat Range. Its low viscosity allows easy application and deep surface penetration, effectively sealing the substrate before overcoating. This solvent-free, low-odour primer ensures outstanding adhesion, durability, and chemical resistance, making it ideal for industrial, commercial, and high-performance environments.

Key Features

• Outstanding adhesion to concrete

• Two-pack epoxy system

• Solvent-free and low odour

• Excellent chemical resistance

• Clear/cloudy amber appearance
  

Surface Preparation

To be assured of maximum adhesion and properties from AndCoat resin products the correct surface preparation is essential. The concrete substrate must be a minimum of 28 days old and the residual moisture content must be a maximum of 75% RH. The substrate should be sound with a minimum compressive strength of 25 N/mm² and minimum pull-off strength of 1.5 N/ mm². The surface must be clean, dry and free of contaminants such as dirt, oil, grease, coatings and surface treatments. If in doubt, apply a test area first. Concrete substrates should be mechanically prepared using vacuum enclosed abrasive blast cleaning or diamond grinding equipment to remove laitance and previous surface treatments leaving an open textured surface. Weak concrete must be removed and repaired using recommended AndCoat products.

Technical Data

• Coverage: 4m² per kg

• Recoatable after 8 hours

• Shelf life: 12 months

Directions for Use

Apply the mixed material with a short to medium pile lamb’s wool roller making sure
that the surface is thoroughly wetted out . If additional coats of primer are required, these
should be applied 12 to 24 hours after the first coat has cured (see Curing Time) and a
minimum of 6 hours and no later than 24 hours after the first coat has cured for AndCoat Prime FC. The first coat must not be contaminated prior to applying the second coat.
The ambient temperature of the works area should be a minimum of 15°C during the
application and curing period, if not adhered to this can affect the performance of the system. Materials and substrate temperature must be above 10°C.
