.3 Prior to commencement of repainting work, thoroughly examine (and test as required) all conditions and surfaces scheduled to be repainted and report in writing to the Contract Administrator any conditions or surfaces that will adversely affect work of this section.


.4 The degree of surface deterioration (DSD) shall be assessed using the assessment criteria indicated in the MPI Maintenance Repainting Manual. In general the MPI DSD ratings and descriptions are as follows:

Condition Description

DSD-0 Sound Surface (may include visual (aesthetic) defects that do not affect film’s protective properties).

DSD-1 Slightly Deteriorated Surface (may show fading; gloss reduction, slight surface contamination, minor pin holes scratches, etc.) / Minor cosmetic defects (runs, sags, etc.).

DSD-2 Moderately Deteriorated Surface (small areas of peeling, flaking, slight cracking, staining, etc.).

DSD-3 Severely Deteriorated Surface (heavy peeling, flaking, cracking, checking, scratches, scuffs, abrasion, small holes and gouges).

DSD-4 Substrate Damage (repair or replacement of surface required by others).

.5 Other than the repair of DSD-1 to DSD-3 defects included under this scope of work, structural and DSD-4 substrate defects discovered prior to and after surface preparation or after first coat of paint shall be made good and sanded by others ready for painting, unless otherwise agreed to by the City of Winnipeg and painter to be included in this Work.

.6 No repainting work shall commence until all such DSD-4 adverse conditions and defects have been corrected and surfaces and conditions are acceptable to the Painting Contractor. The Painting Contractor shall not be responsible for the condition of the substrate or for correcting defects and deficiencies in the substrate, which may adversely affect the painting work except for minimal work normally performed by the Painting Contractor and as, indicated herein. It shall always, however, be the responsibility of the Painting Contractor to see that surfaces are properly prepared before any paint or coating is applied. It shall also be the Painting Contractor’s responsibility to paint the surface as specified providing that the Owner accepts responsibility for uncorrected DSD-4 substrate conditions.

3.3 Preparation of Surfaces

.2 Where required, pressure wash exterior surfaces prior to repainting in accordance with MPI standards for type of surfaces and recommended pressures to ensure complete removal of all loose paint, stains, dirt, and other foreign matter. This work shall be carried out only by qualified tradesman experienced in pressure water cleaning. The use of water hose cleaning will not be considered satisfactory, unless specifically specified. Allow sufficient drying time and test all surfaces using an electronic moisture meter before commencing work.


.3 Sand, clean, dry, etch, neutralize and/or test all surfaces under adequate illumination, ventilation and temperature requirements.

.4 Remove and securely store miscellaneous hardware and surface fittings/fastenings (e.g. electrical plates, mechanical louvers, door and window hardware (e.g. hinges, knobs, locks, trim, frame stops), removable rating / hazard / instruction labels, washroom accessories, light fixture trim, etc. from wall, ceiling and soffit surfaces, doors and frames, prior to repainting and replace upon completion. Carefully clean and replace such items upon completion of repainting work in each area. Do not use solvent or reactive cleaning agents on items that will mar or remove finishes (e.g. lacquer finishes). Doors shall be removed before repainting to paint bottom and top edges and then re-hung.

.5 Protect adjacent interior surfaces and areas, including rating and instruction labels on doors, frames, equipment, piping, etc., from interior painting operations and damage by drop cloths, shields, masking, templates, or other suitable protective means and make good any damage caused by failure to provide such protection.

.6 Protect all exterior surfaces and areas, including landscaping, walks, drives, all adjacent building surfaces (including glass, aluminum surfaces, etc.) and equipment and any labels and signage from exterior painting operations and damage by drop cloths, shields, masking, templates, or other suitable protective means and make good any damage caused by failure to provide such protection.
