     Guide Specification Exterior Repainting

     Revision April 2010 Page 6 of 15

     SPEC NOTES: .1 The use of water borne versus oil based paints and coatings requires careful evaluation. The release of VOC’s and solvent vapours during painting and cleanup, particularly in confined areas and where such vapours may prove offensive to individuals in an occupied facility are a consideration, as well as the oft forgotten residue flushed down the drain during water-borne paint cleanup. Any evaluation must be carefully and dispassionately considered based on actual VOC content of the product used and that released over the life cycle term, on actual site conditions and on long-term durability and life cycle costing requirements. .2 In assessing the requirements for selection of an environmentally friendly water borne or oil based paint product, total VOC content and life cycle / durability must be considered. Refer to MPI Approved Products Listing for the VOC content level of paint products and to the MPI website (www.paintinfo.com) for current information.

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

    entrapment, etc. Refer to 3.5, Field Quality Control / Standard of Acceptance requirements.

     Guide Specification Exterior Repainting

     Revision April 2010 Page 7 of 15

    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.

    .3 Color selection will be based on [four (4)] base colors and [two (2)] accent colors [with a maximum of [one (1)] deep

    or bright color]. No more than [six (6)] colors will be selected for exterior painting work on this project. Note that this

    does not include pre-finished items unless specifically scheduled.

     SPEC NOTE: Revise number of colors and schemes to suit project requirements.

    .4 Exterior [doors shall be repainted a different color than door frames and trim with walls a different color than either]

    [doors, frames and trim shall be repainted a different color than walls] [the same color as adjacent walls]. Unless

    otherwise noted all doors, frames and trim shall be repainted using a G5 (semi-gloss) finish.

    .5 Exterior [window frames (unless pre-finished) including trim and sills shall be repainted [a different color than walls]

    [the same color as walls] [window frames (unless pre-finished) shall be repainted a different color than window trim

    and sills and a different color than walls]. Unless otherwise noted all window frames, trim and sills shall be repainted

    using a G5 (semi-gloss) finish.

    .6 [Exterior parking bay lines, numbers and symbols including barrier free accessible parking bays and pedestrian

    walkways shall be repainted white or yellow to suit existing color and/or in accordance with the requirements or

    authorities having jurisdiction.]

    .7 [Provide a slip resistant additive to exterior painted stair treads where noted on the Finish Schedule or where required

    by authorities having jurisdiction.]

2.5 Gloss / Sheen:

    .1 Paint gloss shall be defined as the sheen rating of applied paint, in accordance with the following MPI gloss / sheen

    standard values:

     Gloss Description Units Units

    Level @ 60 degrees @ 85 degrees

    Matte or Flat finish 0 to 5 10 maximum G1 Velvet finish 10 maximum 10 to 35 G2 Eggshell finish 10 to 25 10 to 35 G3 Satin finish 20 to 35 35 minimum G4 Semi-Gloss finish 35 to 70 G5 Gloss finish 70 to 85 G6 High-Gloss finish > 85 G7

    .2 Gloss level ratings of all painted surfaces shall be as specified herein and as noted on Finish Schedule.

     SPEC NOTES: .1 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. .2 Unless otherwise approved by the painting inspection agency having jurisdiction, the use of deep colors or high contrast accent colors will require a minimum of three or more finish coats over primer to achieve satisfactory hiding results. .3 Caution should be used when specifying deep colors in high traffic areas, regardless of the surface to which these colors are applied. Deep tinted color in a flat, eggshell, semi-gloss and to some extent high gloss finish will mar easily and leave an unsightly appearance with loss of sheen and with considerable reduction of abrasion resistance. Refer to MPI Repainting Manual.
