Topcoats
Not recommended
Dry Film Thickness
16.0 mils (400 microns) in one or two coats. Total dry film thickness less than 8 mils (200 microns) or in excess of 35 mils (875 microns) not recommended.
Solids Content
By volume: 74% ± 2%
Theoretical Coverage Rate
1187 mil ft2 (29.1 m2/I at 25 microns). Allow for loss in mixing and application.
Immersion temperature should not exceed 120°F (49°C).
Limitations
Do not use for potable water requirements.
Substrates & Surface Preparation
General
Surfaces must be clean and dry. Employ adequate methods to remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating.
Steel
Immersion: SSPC-SP10. Non-Immersion: SSPC-SP6 for maximum protection. SSPC-SP2 or SP3 as minimum requirement. Surface Profile: 2.0-3.0 mils (50-75 micron).
Concrete
Concrete must be cured 28 days at 75°F (24°C) and 50% relative humidity or equivalent. Prepare surfaces in accordance with ASTM D4258 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete. Voids in concrete may require surfacing.

Application Equipment
Spray Application (General)
This is a high solids coating and may require adjustments in spray techniques. Wet film thickness is easily and quickly achieved. The following spray equipment has been found suitable and is available from manufacturers such as Binks, DeVilbiss and Graco.
Conventional Spray
Pressure pot equipped with dual regulators, 3/8" LD. minimum material hose, with 50' maximum material hose .086" LD. fluid tip and appropriate air cap.
Airless Spray
Pump Ratio: 30:1 GPM Output: 3.0 (min.) Material Hose: 1/2" ID. (min.) Tip Size: 023-.035" Output PSI: 2300-2500 Filter Size: 30 mesh Teflon packings are recommended and available from the pump manufacturer.
Brush & Roller (General)
Recommended for touch up, striping of weld seams (General) and hard-to-coat areas only. Avoid excessive rebrushing or re-rolling.
Brush
Use a medium bristle brush.
Roller
Use a short-nap synthetic roller cover with phenolic core.
Mixing & Thinning
Mixing
Power mix separately, then combine and power mix for a minimum of two minutes. DO NOT MIX PARTIAL KITS.
Ratio
4:1 Ratio (A to B)
Thinning
Up to 20 oz/gal (16%) with Thinner #10. Up to 25 oz/gal (20%) Thinner #10 #10 for the first coat application to concrete. Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied.
Pot Life
75°F (24°C): 3 Hours 90°F (32°C): 1 Hour Pot life ends when coating loses body and begins to sag.
Cleanup & Safety
Cleanup
Use #2 Thinner or Acetone. In case of spillage, absorb and dispose of in accordance with local applicable regulations.
Safety
Read and follow all caution statements on this product data sheet and on the MSDS for this product. Employ normal workmanlike safety precautions. Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands and all exposed areas.
Caution
This product contains flammable solvents. Keep away from sparks and open flames. All electrical equipment and installations should be made and grounded in accordance with the National Electric Code. In areas where explosion hazards exist, workmen should be required to use non-ferrous tools and wear conductive and non-sparking shoes.
Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate. Special application techniques may be required above or below normal application conditions.

These times are based on a 16.0 mil (400 micron) dry film thickness. Higher film thickness, insufficient ventilation, high humidity or cooler temperatures will require longer cure times. Excessive humidity or condensation on the surface during curing can interfere with the cure, can cause discoloration and may result in a surface haze. Any haze or blush _must be removed by water washing before recoating. If the maximum recoat time is exceeded, the surface must be abraded by sweep blasting prior to the application of additional coats. Holiday Detection (if required): Wet sponge types may be used if the dry film thickness is below 20 mils (500 microns). High voltage spark testing should b e used when the dry film thickness exceeds 20 mils (500 microns). Refer to NACE RP0188-90 for specific procedures.

Bitumastic is a century-old trade name that is often associated with long-term protection from water penetration. Typically made from coal tars and blends of resins such as epoxy, these products have been used as tank linings, to coat the interior and exterior of buried pipe, and to protect equipment subjected to water immersion.
