Blue Seal is superior to all performance coatings and will adhere smoothly and quickly to sandblasted surfaces. Because surface types and locations vary, Blue Seal may be thinned or thickened as needed to maximize results without reducing protective coating effectiveness.

Spray, brush or trowel onto pits, pinholes, cracks, dents, punctures and even small holes to rebuild surfaces to required specifications.  Blue Seal can be used to repair deteriorated machinery or components, tankage and hulls to better than new conditions while giving long term protection from further damage.

Blue Seal can be sprayed up to 4,000 square feet per hour and because of the efficiency of the application process, it eliminates the need for frequent cleaning of the spray equipment.

Surfaces Applied To
Blue Seal will adhere powerfully to:

  • All ferrous metals including steel, cast iron, etc.
  • All non-ferrous metals including aluminum, brass, stainless steel, copper, etc.
  • Fiberglass
  • Wood
  • Concrete
  • Plastic
  • Fairing Compounds
Color Choices

Standard colors are blue, grey, white and black. The use of blue is most common as it is unique and a valuable tool in determining where Blue Seal has been applied. Custom colors can be mixed to any Pantone color.

Coverage

Base and topcoat:

60 sf per US gal/1.3 m² per kg @ 10 mils/250 microns per coat

Reinforcement:

43 sf per US gal/1.0 m² per kg @ 15 mils/380 microns per coat

Surface Preparation

Abrasive blast surfaces to white metal. Smooth out weld seams and sharp edges. If applying on concrete, high pressure water or abrasive blast. Fill and reinforce any cracks. Ensure all surfaces are clean, dry and free from contaminants. Apply coating immediately after blasting.

Mixing Instructions

Thoroughly mix product after opening container. For large containers, use a power mixer. Pour into a plastic mixing container only the amount of Blue Seal that may be applied within 15 minutes. Do not use a mixing paddle that has been used with catalyzed material.

Application

Brush – recommended for small areas.

For best adhesion, first apply one layer of basecoat at 10-15 mils/250-300 microns thickness. Thoroughly rub basecoat onto surface to fill any voids and to ensure 100% coverage. Brush on one layer of reinforcement, then trowel on second layer of reinforcement. Sand any surface imperfections, then apply one layer of topcoat.

Sprayer – recommended for large areas.

Use conventional airless spray equipment. For best results, use a spray system that mixes the coating with catalyst and apply one base coat, one to two reinforcement coats and one top coat.

Inspection
After coating, surfaces should be inspected with a porosity/holiday detector. All defects must be re-coated and re-tested.

Packaging
Blue Seal is packaged in US quart, one gallon, five gallon pails, and 55 gallon drums. For international shipments, product is sold by weight in 1,5 and 20 kg units. Sufficient catalyst is included with all coating units. Additional glass flake may be ordered as needed.

Storage
Store unopened containers in dry, shaded conditions away from heat and ignition sources and above freezing temperatures. For best results, store at a temperature range of 60° F/16° C to 77° F/25° C.

Shelf Life
Six months when stored at 68° F/20° C.

Safety
When applying Blue Seal, always wear gloves and appropriate protective clothing. If spraying in confined areas, use full body protection and a fresh air-fed mask and any other required confined space safety equipment. See MSDS sheet for further product information prior to handling product. Blue Seal is for industrial and professional use only. All application instructions must be followed.
