- All coating materials shall be mixed and thoroughly stirred in accordance with the
instructions of the paint Manufacturer. Sufficient agitation to maintain good mixing shall be
applied until the product is used. If air is entrapped in the product during mixing/stirring,
sufficient time should be allowed for the air bubbles to escape before application.
- To the maximum extent practicable, each coat of material shall be applied as a continuous
film uniform thickness free of porous. Any spots or areas missed in application will be
recoated and permitted to dry before the next coat is applied. Applied paint must have the
desired wet film thickness.
- For coating different color shades are used for primer and intermediate coats, for ease in
monitoring and identification of the number of coats
- Each paint coat will be smooth, free of defects, fully bonded, and of proper thickness. Any
runs and sags will be removed. The top coat shall have a smooth and uniform color and
finish.
- Instruments, machined or polished bright metal surfaces, the mating surfaces of flanged
joints, and the insides of open pipe ends shall be protected during surface preparation and
painting.
- Macventure will supply and lay drop cloths to protect other work, equipment, and surfaces. After
completion Macventure cleans off any spilled or spattered paint.
- No coat shall be applied until the preceding coat has dried and cured as recommended by
Paint Manufacturer. Next coat will be applied within the time stipulated by the paint
manufacturer.
- Before over coating, over-runs, drips and smears shall be removed and any coating damage
or imperfection will be repaired. The material shall be considered dry for re-coating when
another coat can be applied without the development of any film irregularities such as lifting
or loss of adhesion of undercoats.
- Before overcoating an epoxy paint, the surface shall be checked for amine blush. If any
greasy or waxy film is detectable, then the entire surface shall be thoroughly washed with
clean water and dried.
- Contamination of the surfaces between coats shall be prevented. If contamination does
occur, surfaces shall be pressure washed and dried before the next coat of paint is applied.
- No paint shall be force dried.
- No drier shall be added to paint on the job unless specifically called for in the manufacturer’s
specification for the paint. Paint shall be protected from rain, condensation and
contamination until dry.
- To minimize the risk of damage, no lifting, transportation, erection or fabrication operations
shall be done before the paint has been fully dried and/or cured.
- Damaged areas, defects in the coating system such as over-runs, drips and smears that have
to be removed or areas with inadequate dry film coating thickness shall be re-cleaned.
- Only thinners specified by the paint Manufacturer will be used.
- The temperature of the paint shall be per the product data sheet.
- After the item is finish painted, it shall be marked to identify the paints that were used by
manufacturer and product number, and the date. The markings are be made directly on the
equipment on permanent labels.
- Application restrictions, we cannot paint:
o During fog, mist or rain.
o When the relative humidity is 85 percent or above.
o When the surface temperature and/or ambient temperature is below 10°C.
o When the surface temperature and/or ambient temperature is above 35°C.
o When the steel surface temperature is less than 3°C above the dew point.
