Method Statement for Internal Painting Works

Before commencement of work, remove electrical switch and outlet plates, surface hardware, frames of lighting fixtures and all other obstructions. Replace properly at completion of the work.

Remove soiled and used rags, waste and empty containers from the building each night. Take every precaution to prevent a fire.

Preparation Before Painting

Clean floors and adjacent surfaces, as well as surfaces to be painted, before work is commenced. Cut out, as required, defects in drywall and plaster surfaces and openings adjoining trim, and fill with a patching compound or approved patching plaster flush with adjoining surface. When dry, smooth and-seal the patch before application of the priming coat.

  • Fill nail holes, and similar defects after the first coat of paint has been applied. Filler to match the colour of the finish.
  • Carefully hand sand woodwork before painting.
  • Clean and remove all defects and extraneous matter from surfaces to be finished.
  • Inspect wood surfaces for gouges, marks, and other defects and properly prepare by patching, filling, smoothing or surface preparation as necessary to insure a satisfactory surface for priming.
  • Remove from ferrous metals, rust, scale and loose paint by means of scrapers and wire brushes or blasting.
  • Neutralize galvanized surfaces with approved proprietary brand neutralizing (etching) solution.
  • Remove all foreign matter on surfaces before painting.
  • Prime on wood, with one coat of aluminum primer, if to be finished with paint.
  • Test all surfaces for moisture content before commencing painting. Do not apply paint when moisture content exceeds 8%, as determined by an approved moisture testing device.
  • In the case of presence of high alkali conditions, wash surface to neutralize the alkali.
  • Wire-brush concrete and masonry surfaces.
  • Advise consultant at least three days prior to application, of the use of special preparatory treatment.
  • Cement plastered surfaces to be rubbed down with rubbing stone, or approved method and cleaned of dust and all foreign matter before application of primer.

painting work methods

Application Of the Painting Works

  • Do not undertake exterior painting at temperatures outside of paint manufacturer’s recommended application and curing temperature and humidity range, or immediately following rain and dew. Avoid painting surfaces when exposed to hot sun.
  • Thoroughly mix materials before paint application.
  • Apply paint under adequate illumination.
  • Apply materials and cut in neatly, so as to dry uniformly to the color and gloss specified, free from runs, sags, wrinkles, crawls and other defects.
  • Vary each coat in tone to permit supervision identification.
  • Sand lightly between coats of paint.
  • Each coat of paint to be dry and hard before following coat is applied.
  • Finish tops, bottoms and edges of doors in the same manner as the remainder of the door.
  • When the primer-sealer coat is dry, touch up all visible suction spots before the next coat is applied, do not proceed until all suction spots are sealed.
  • Where exposed pipes are to be painted, also include copper piping.
  • Unless otherwise specified, finish all other surfaces the same as the nearest or adjoining surfaces or as directed by consultant/client.
  • Brush paint wood and metal surfaces.
  • Unless otherwise specified, apply paint by roller unless the manufacturer’s recommendation excludes use of this method.

Priming Works

  • Prime ferrous metal surfaces including, without being limited to, steel, mechanical and electrical equipment, piping, ducts and conduit that have not received a shop coat of paint, with a coat of epoxy zinc primer or equivalent alkyd rust-inhibiting primer compatible with finish coating.
  • Prime galvanized or zinc-coated surfaces including, without being limited, to flashing, handrails, piping and ductwork with one coat of galvanized steel primer compatible with the finish coating.
  • Touch up with primer metalwork which has received a shop primer and which is to be finish painted, after loose paint and scale have been removed.
  • Prime or seal with compatible primer/sealer, surfaces, immediately after delivery to the building, if the work has not already received a primer. Reprime or reseal all edges of materials cut on job.
  • Prime surfaces of interior concrete with one coat of specified primer, compatible with finish paint.
  • Prime surfaces of concrete and block masonry with one coat of primer compatible with finish paint and filler.
Painting of Metal Work
  • Apply coats of interior paint over the prime coat of all interior metalwork which will be exposed in the finished Work, other than stainless steel, brass, bronze and other specifically excluded metals.
  • Paint, without being limited to, all interior mechanical and electrical equipment, ductwork and piping and other exposed steel not noted to be painted under other sections of the Specifications.
  • Paint exterior roof-mounted mechanical equipment and piping.
