RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURES

• Coating performance is, in general, proportional to the degree of surface preparation
• Abrasive blasting is usually the most effective and economical method. When this is impossible or impractical, coating
can be applied over mechanically cleaned surfaces
• All surfaces must be clean, dry and free of all contaminants, including salt deposits. Contact PPG for maximum allowable
salt containment levels

Mild steel
• Remove all loose rust, dirt, grease or other contaminants by one of the following depending on the degree of cleanliness
required: SSPC SP-2, 3, 6, 7 or 10 (ISO 8501-1 St-2, St-3, Sa 1, Sa 2, Sa 2.5). These minimum surface preparation
standards apply to steel that has been previously abrasive blasted. The choice of surface preparation will depend on the
system selected and end-use service conditions
• For immersion and severe duty applications, the recommended blast profile is 2.0 – 4.0 mils (50 – 100 µm). Previously
blasted steel may be ultra-high pressure water jetted to SSPC -SPWJ-2(L) / NACE WJ-2(L). The wet surface can be dried
by blowing with dry compressed air giving special attention to horizontal surfaces and recesses

Concrete
• Remove grease, oil and other penetrating contaminants according to ASTM D4258
• Abrade surface per ASTM D-4259 to remove all efflorescence and laitance, to expose subsurface voids, and to provide a
surface roughness equivalent of 60 grit sandpaper or coarser
• AMERCOAT 114 A may be used as a pit filler. Check with PPG Technical Service for alternative
• Maximum recommended moisture transmission rate is 3 lbs / 1,000 ft2 / 24 hours by moisture transmission test (ASTM
F1869, calcium chloride test or by ASTM D4263, plastic sheet test)
• Alternatively, ASTM D4944 (Calcium Carbide Gas method) can be used, moisture content should not exceed 4%

PRODUCT DATA SHEET April 16, 2018 (Revision of June 2, 2017)

AMERCOAT® 385

Galvanized steel
• Remove oil or soap film with detergent or emulsion cleaner
• Lightly abrasive blast with a fine abrasive in accordance with SSPC SP-16 guidelines to achieve a profile of 1.5 – 3.0 mils
(38 – 75 µm). When light abrasive blasting is not possible, galvanizing can be treated with a suitable zinc phosphate
conversion coating.
• Galvanizing that has at least 12 months of exterior weathering and has a rough surface with white rust present may be
over-coated after power washing and cleaning to remove white rust and other contaminants
• The surface must have a measurable profile
• A test patch is recommended to determine compatibility and adhesion
• Not recommended over chromate sealed galvanizing without blasting to thoroughly remove chromates. Adhesion
problems may occur

Non-ferrous metals and stainless steel

• Abrasive blast in accordance with SSPC SP-16 guidelines to achieve a uniform and dense 1.5-4.0 mils (38 – 100 µm)
anchor profile. Size and hardness of abrasive should be adjusted as necessary based on the hardness of the substrate
• Aluminum may be treated with a surface treatment compliant with Mil-DTL-5541 or equivalent (non-immersion
applications only).

Aged coatings
• All surfaces must be clean, dry, tightly bonded and free of all loose paint, corrosion products or chalky residue
• Abrade surface, or clean with PREP 88. This product is compatible over most types of properly applied and tightly
adhering coatings, however, a test patch is recommended to confirm compatibility

Repair
• Prepare damaged areas to original surface preparation specifications, feathering edges of intact coating. Thoroughly
remove dust or abrasive residue before touch-up.

Substrate temperature and application conditions

• Surface temperature during application should be at least 5°F (3°C) above dew point
• Ambient temperature during application and curing should be between 40°F (4°C) and 122°F (50°C)
• Relative humidity during application should not exceed 85%

SYSTEM SPECIFICATION
• Primers: Direct to substrate; DIMETCOTE- Series Primers, AMERCOAT 68HS, AMERCOAT 68MCZ
• Topcoats: AMERCOAT 450-Series Polyurethanes, AMERSHIELD, PSX 700, AMERCOAT 229T, PITTHANE Polyurethanes

INSTRUCTIONS FOR USE

Mixing ratio by volume: base to hardener 50:50 (1:1)
• Pre-mix base component with a pneumatic air mixer at moderate speeds to homogenize the container. Add hardener to
base and agitate with a power mixer for 1–2 minutes until completely dispersed

Notes:
- Dry times are dependent on air and surface temperatures as well as film thickness, ventilation, and relative humidity. Maximum
recoating time is highly dependent upon actual surface temperatures – not simply air temperatures. Surface temperatures should be
monitored, especially with sun-exposed or otherwise heated surfaces. Higher surface temperatures shorten the maximum recoat
window
- Surface must be clean and dry. Any contamination must be identified and removed. A detergent wash with PREP 88 or equivalent is
required prior to application of topcoats after 30 days of exposure. However, particular attention must be paid to surfaces exposed to
sunlight where chalking may be present. In those situations, a further degree of cleaning may be required. PPG Technical Service can
advise on suitable cleaning methods. If maximum recoat/topcoat time is exceeded, then roughen surface.
