Key properties

• Suitable for application over existing coatings on steel or directly onto concrete/masonry surfaces.
• Pit filler putty / weld repair coating
• Used to fill and repair defects, holes/voids and cracks in concrete surfaces
• Suitable for use as a repair putty for masonry and as a plaster-type primer
• Excellent chemical resistance

Colour and gloss

• Off-white

Basic parameters — at 20 °C (68 °F)

Parameters after mixing

Curing agent: at least 36 months; store in a dry and cool environment.

Notes

• First "feather" the surrounding substrate surface, then apply the putty; after filling, trowel the coating at the original holes and gaps to a flat, smooth finish flush with the substrate surface, at the same plane, with no

visible ridges.

Recommended substrate condition and temperature

Bare steel

• Abrasive blast cleaning to SSPC SP-10. Prior surface preparation shall be carried out in accordance with the requirements of the specified primer.

Concrete substrate

• Concrete substrates require a minimum cure of 14 days; ensure that the expected physical properties of the concrete substrate have reached more than 80% before coating.
• Surface preparation shall be carried out in accordance with ASTM D4258 (surface cleaning) and ASTM D4259 (surface abrading), or ASTM D4260 (acid etching).
• Remove loose dust particles from gaps and voids by compressed air blow-off or vacuum extraction.

Concrete blocks

• Walls must be plumb and at right angles to flush joints. Joints shall not be sloped.
• All surfaces must be clean and dry and comply with the requirements of ASTM D4261.

Substrate Temperature

• Surface temperature during application shall be maintained between 50°F (10°C) and 120°F (49°C).
• During application, the substrate surface temperature shall be at least 3°C (5°F) above the dew point.
• Ambient temperature during application and coating cure shall be maintained between 50°F (10°C) and 120°F (49°C).
• Relative humidity during application shall be maintained between 0% and 85%.

Coating system specification

• Primer: apply directly to concrete surfaces or over an epoxy sealer coat.
• For steel as previous coat: epoxy zinc-rich series AMERCOAT 68HS and AMERCOAT 68MCZ, AMERCOAT series epoxy coatings, AMERLOCK series
• Subsequent coats: AMERCOAT series epoxy coatings and PITTGUARD series epoxy coatings

Instructions for use

Mixing ratio by volume: base component:curing agent component = 65:35

• First pre-mix the pigmented component with an air-driven stirrer at medium speed. Then, while stirring, slowly pour the curing agent component into the container holding the base

component, and continue stirring for about 1–2 minutes until the two components are fully dispersed and thoroughly mixed to a homogeneous state.

• Frequent scraping of the bottom and sides of the can is required to ensure all paint components are fully mixed. Only complete kits shall be mixed in a single operation.

Induction Time

Not required.

Application

• Epoxy Surfacer 114A may be applied by short-nap roller, trowel, putty knife, rubber squeegee or a combination of these methods. Apply with steady, even pressure so that the film

spreads out to form a coating of uniform thickness and smooth surface. The film remaining on large flat areas shall be as thin and as little as possible.

• A trowel with rounded edges may be used to form a 1 inch concave cove.
• Epoxy Surfacer 114A may be used to fill and repair surface voids up to 1 inch in width or depth
• Epoxy Surfacer 114A is not an elastomer and shall not be used to bridge or seal cracks.
• Mask off the application area to prevent airborne dust settlement and other contamination.
• Avoid combustion exhaust gases contaminating or accumulating around the surface, thereby reducing or retarding amine bloom and yellowing (amber tendency) of light-coloured coatings.
• Ensure continuous, adequate ventilation throughout application and curing.
• For further information on how to prevent, inspect and remove amine bloom, refer to Bulletin #1489.

Material temperature

During application and coating cure, surface temperature should be controlled between 50°F (10°C) and 90°F (32°C).

Supplementary parameters

Overcoating interval schedule for a 125 µm (5.0 mil) dry film thickness

Notes

• The drying time of the film depends on the ambient air and substrate surface temperatures, the film thickness, ventilation and relative humidity. The maximum overcoating interval is determined mainly by the actual surface temperature

rather than simply the ambient air temperature. The substrate surface temperature shall be monitored. The higher the substrate surface temperature, the shorter the maximum overcoating interval.

• The surface shall be clean and dry. All contamination shall be identified and removed. Pay particular attention to coatings directly exposed to weathering, which may show surface chalking. In such cases,

thorough cleaning is required; if in doubt, consult the PPG field technical service representative. If the specified maximum overcoating interval has been exceeded, abrading is required.
