Industrial protective coating for metal and plastics. Single component designed for permanent flexibility and toughness to protect underwater surfaces.








24 Standard Colors. Custom Colors are available.


POLACAV is a premium quality single component on-site industrial protective coating for metal and plastics.  It is solvent-based and may be applied in any temperature range.  POLACAV is designed for permanent flexibility and toughness, to bridge and move with hairline cracks, and to resist impingement attack.  POLACAV has excellent adhesion underwater in fluid flow environments and will protect against the destructive impact of cavitation.  It is used successfully in the repair of turbines, propellers, pumps, chutes, flumes, grates and tanks.

Outstanding Features

  • Sets quickly and builds strength rapidly after application
  • User-friendly application rheology produces consistency of quality results
  • Provides long-term protection against cavitation and impact fatigue
  • Is re-coatable without the need to shot-blast
  • Biologically inert, will not leech out any toxic materials
  • Is tolerant of less-than-perfect application conditions
  • Significant erosion resistance under turbid flow conditions
  • Resists cyclic fatigue from rapid thermal fluctuations
  • Improves traction under wet conditions

Recommended for

Can be used over concrete, stucco, mineral composites, bricks/masonry, fibreglass composites, most metals, insulation, porous stone, non-porous stone, urethane foam and other surfaces.

Preparation and Application

Surface Preparation
Surfaces to be coated must be dry and free of loose debris, dirt, oils, grease, or any other substance that could interfere with proper bond.

All repairs to the substrate must be completed prior to application of POLACAV. Worn steel surfaces may be rebuilt with machinable epoxy; concrete may be restored with Polafloor Epoxy Topping and Polajoint. Fiberglass reinforced polyester and other plastics may be repaired with Polafab and Polaprime Epoxy or Andek 950.

POLACAV may be applied straight from its container after 2 minutes of low speed power stirring. Apply POLACAV using brush or roller. Apply 2 coats of POLACAV in a smooth, even fashion to achieve a uniform coating thickness of 15 wet mils per coat. Allow the first coat adequate time to dry before application of the second coat.

Spray Application
Utilize a 45:1 airless pump, a 1/2″ hose, 3/4″ whip and a 31 width tip

Clean up
Equipment may be cleaned with xylene or toluene before POLACAV begins to dry.

Do not apply to wet, damp, or frozen surfaces. Proper surface preparation and priming where required are very important to product performance. Surface must remain at least 5°F above dew point during the application and curing process. Shelf life is 2 years when stored indoors in factory sealed containers. This product is combustible. Keep away from heat, sparks and flame. Use only EP (explosion-proof) rated equipment.

Read the container label warning and Safety Data Sheet (SDS) for important health and safety information prior to the use of this product.
