SPEC NOTE: Current range of ecologo paint products is limited. Use caution when specifying such products exclusively.

.5 All paint materials shall have good flowing and brushing properties and shall dry or cure free of blemishes or sags.

.6 Where required, paints and coatings shall meet flame spread and smoke developed ratings designated by local Code requirements and/or authorities having jurisdiction.

SPEC NOTE: Insert required rating and/or testing requirements if appropriate.

.7 Glass reflective beads (for pavement marking) ‑ of type suitable for application to a wet paint surface for light reflectance. Apply beads at a minimum rate of 0.5 kg/l (5 lbs/g) to a white and/or yellow latex or alkyd zone/traffic marking paint of approved type as listed in the TRG Architectural Painting Specification Manual.

.8 Slip resistant additives (SRA) ‑ rubber aggregate, clean/washed silica sand or ground walnut chips (interior dry areas only) for use with or as a component part of paint (usually floor/porch/stair enamel) on horizontal surfaces as required to provide slip resistance. Where site applied, material to either mixed into paint (and mixed constantly to keep material in suspension) or broadcast into first or prime coat as required.

2.2 Equipment:

.1 Painting and decorating equipment - to best trade standards for type of product and application.

· satin ‑ 20 to 35 units at 60 degrees.

· semi‑gloss ‑ 35 to 65 units at 60 degrees.

· gloss ‑ 65 units and greater.

SPEC NOTE: A high gloss finish provides more physical and stain resistance with such painted surfaces appearing to have a “hard” finish. Such glossy finishes, however tend to enhance textures or defects of the surface to which they are applied. Use of higher gloss finishes should be reviewed from the point of view of excessive surface preparation required which might not be warranted for the surface to be coated.

SPEC NOTE: Gypsum board shall be finished by others to specified levels of finish recognized by the drywall industry to suit project requirements. The specifier should be aware of the limitations of such levels of finish particularly when semi-gloss and gloss paints are applied to such surfaces. Where a smooth, high quality or gloss appearance is required over gypsum board (i.e., where semi-gloss, gloss, or non-textured flat finishes or dark colors are applied or where severe or critical lighting conditions occur) a Level 5 finish (three coats of sanded joint compound with a thin skim coat of joint compound or similar material applied to entire board surface) is recommended. The gypsum board finish is to be assessed by the drywall applicator for imperfections prior to the application of paint finishes. The specifier is to ensure that the appropriate levels of gypsum board finishes are specified to suit expected (painted) finish appearances.

.2 Finish (i.e. gloss level) of all painted surfaces shall be as specified herein or as noted on Finish Schedule.

2.5 Finishes:

.1 Colors shall be as selected by the Consultant from a manufacturer’s full range of colors. (Refer to Finish Schedule for identification and location of colors)(The schedule will be furnished after award of the Contract, except general requirements shall be as noted herein).

SPEC NOTE: Note that Finish Schedules, in addition to other materials, shall not only include all exterior and interior painted items (eg. siding, doors, frames, trim, base, sills, walls, decks, railings, etc.) on the schedule but also indicate color number and gloss required.

In addition, where more than one color is used on a wall this shall be scheduled.

Generally and unless otherwise specified herein or noted on Finish Schedules the quantity of colors and finishes shall be based on the following criteria:

SPEC NOTE: Delete, revise or add to the following example selections below to suit project requirements.

.2 Color selection will be based on (five (5) base colors and (three) accent colors (with a maximum of (one (1) deep or bright color). No more than (eight (8) colors will be selected for the entire project and no more than (three (3) colors will be selected in each area.

PART 3 ‑ EXECUTION

3.1 Condition of Surfaces:

.1 Prior to commencement of work of this section, thoroughly examine (and test as required) all conditions and surfaces scheduled to be painted and report in writing to the Contractor and Consultant any conditions or surfaces that will adversely affect work of this section.

.2 No painting work shall commence until all such adverse conditions and defects have been corrected and surfaces and conditions are acceptable to the Painting Subcontractor and Inspection Agency.

.3 Commencement of work shall not be held to imply acceptance of surfaces except as qualified herein. Such surfaces as concrete, masonry, structural steel and miscellaneous metal, wood, gypsum board and plaster, shall not be the responsibility of the Painting Subcontractor.

.4 The Painting Subcontractor 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 minimal work normally performed by the Painting Subcontractor. It shall always however be the responsibility of the Painting Subcontractor to see that surfaces are properly prepared before any paint or coating is applied.

3.2 Preparation of Surfaces:

.1 Prepare all surfaces in accordance with TRG Architectural Painting Specification Manual requirements. Refer to the TRG Manual in regard to specific requirements for the following:

· environmental conditions.

· pH testing.

· acid etching.

· rust stain removal.

· asphalt surfaces.

· vertical and horizontal concrete surfaces.

· clay and concrete masonry units.

· structural steel and miscellaneous metals.

· steel exposed to high heat.

· galvanized and zinc coated metal.

· aluminum and copper surfaces.

· glue laminated beams and columns.

· dimension and dressed lumber.

· wood doors.

· wood paneling and casework.

· wood decks, floors, stairs and steps.

· wood shingles and shakes.

· stucco, plaster and gypsum board.

· acoustical panels and tiles.

· canvas and cotton coverings.

· bituminous coated surfaces.

.2 Protect all adjacent surfaces and areas from 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.

.3 Substrate defects shall be made good and sanded by others ready for painting particularly after first coat of paint. Finish painting of defective surfaces (e.g. gypsum board) shall indicate acceptance of substrate and any costs of making good defects shall be borne by the painter including re‑painting of entire defective surface (no touch‑up painting).

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

SPEC NOTE: Primers (e.g. alkyd, epoxy, zinc, etc.) require overcoating within manufacturer’s specified time limits. After

this time they may become too hard to facilitate good adhesion. This is particularity important in the selection and use of primers in the fabrication of structural steel and miscellaneous metal. Shop cleaning procedures, the selection of the “correct” primer and inspection for such work must be in accordance with TRG Architectural Painting Specification Manual requirements.

SPEC NOTE: Painting work shall be scheduled before the installation of miscellaneous hardware, surface fittings, fastenings, fixtures and trim by others including the hanging of doors and installation of door hardware (see 3.1.5 above). If such items require the removal, storage, and reinstallation, the coordination and onus rests with the General Contractor. Extensive touch-up painting necessary as a result of the installation or re-installation of such fittings by others after painting, shall be considered as additional services at additional cost to the Owner.

3.3 Application:

.1 Do not paint unless substrates are acceptable and/or until all environmental conditions (heating, ventilation, lighting and completion of other subtrade work) are acceptable for applications of products.

.2 Apply paint and decorating material in a workmanlike manner using skilled and trade qualified applicators as noted under Quality Assurance.

.3 Minimum painting standards shall be in accordance with TRG Architectural Painting Specification Manual (Premium)(Custom) Grade finish requirements.

.4 Paint all surfaces requiring paint or stain finish to minimum TRG Architectural Painting Specification Manual finish requirements with application methods in accordance with best trade practices for type and application of materials used.

.5 Apply paint and coatings within an appropriate time frame after cleaning when environmental conditions encourage flash-rusting, rusting, contamination or the manufacturer’s paint specifications require earlier applications.

.6 Painting coats specified are intended to cover surfaces satisfactorily when applied at proper consistency and in accordance with manufacturer’s recommendations.

.7 Tint each coat of paint progressively lighter to enable confirmation of number of coats.

.8 Apply a minimum of four coats of paint where deep or bright colors are used to achieve satisfactory results.

SPEC NOTE: Caution should be used when specifying deep colors in high traffic areas, regardless of the surface to which

these colors are applied. Machine tinted color in flat, eggshell, semi-gloss and to some extent high gloss finish will mark easily and leave an unsightly appearance with loss of sheen and with considerable reduction of abrasion resistance. In such cases, either a clear urethane or high performance acrylic type of coating over such deep colors may solve the problem but may also result in a change in hue and where touch-up painting is required the entire surface will have to be redone from break to break or from corner to corner as spot touch-up will be very noticeable. Refer to TRG Architectural Painting Specification Manual.

.9 Sand and dust between each coat to provide an anchor for next coat and to remove defects visible from a distance up to 1000 mm (39”).

.10 Do not apply finishes on surfaces that are not sufficiently dry. Unless manufacturer’s directions state otherwise, each coat shall be sufficiently dry and hard before a following coat is applied.

.11 Prime coat of stain or varnish finishes may be reduced in accordance with manufacturer’s directions.

.12 Use aggregate coating or a slip resistant additive in paint for stair handrails, treads and landings in accordance with the requirements of authorities having jurisdiction and where scheduled to be painted.
