PART 3 EXECUTION

3.1 EVALUATION

Perform a complete evaluation survey of the existing conditions of each wood window to determine the extent of repairs necessary. The evaluation survey may be in the form of a schedule and must note at a minimum:

a. Window location.

b. Condition of the paint.

c. Condition of the frame and sill.

d. Condition of the interior and exterior trim.

e. Condition of the sash (including rails, stiles, and muntins).

f. Glazing problems.

g. Window hardware and operating system.

h. The overall condition of the window.

3.2 REPAIRS

3.2.1 Example Window

Prepare an existing window of each type to serve as an example of the quality of repairs to be provided for inspection and approval by the Contracting Officer.

3.2.2 Sash Removal

Remove the interior stops first, in a method so as to not scar the wood.

Detach connecting hardware and operating mechanisms and remove the sash from the frame. Identify removed sashes and frames as to location to assure reinstallation in their original positions. For windows with counter-weight systems, detach the sash cords from the sides of the sash and pin their ends with a nail or tie in a knot to prevent them from falling into the weight pocket; the lower sash can then be removed.

Remove the parting bead so as to not scar the wood. Install plastic covering or plywood to cover the window opening during repairs.

3.2.3 Paint Removal

Remove paint from areas on frame, sill, sash and muntins where paint or varnish has peeled, alligatored, blistered or crazed, to bare wood or first sound paint layer, using non-destructive means such as a chemical stripper or heat gun. If chemical strippers are used, neutralize wood

SECTION 08 01 52 Page 5 after stripping to a litmus pH of 5 to 8.5. Allow wood to dry to a moisture content of 8 to 12 percent before repainting. If heat methods are used for paint removal, protect glass from sudden temperature change to avoid breakage.

3.2.4 Wood Repair

Remove badly decayed areas (with more than 30 percent wood decayed) from wood sash, sill, frame, and trim assemblies. Patch moderately decayed areas (less than 30 percent decayed), weathered, or gouged wood with approved patching compounds, and sand smooth. Repair intact sash rails and stiles that are loose with new dowels to make joints tight.

3.2.5 Epoxy Wood Repair

Apply epoxy wood repair materials in accordance with manufacturer's written instructions. Follow health and safety instructions in accordance with the manufacturer's instructions. Identify the source or cause of wood decay and correct prior to application of patching materials. Dry wet wood to a moisture content of 8 to 12 percent to its full depth before patching. Clean dust, grease, and loose paint from wood that is to be patched. Use clean mixing equipment to avoid contamination. Provide mix and proportions as directed by the manufacturer. Provide batches large enough to complete the specific job intended. Cure patching materials before painting or reinstalling patched pieces.

3.2.5.1 Epoxy Liquid Wood Consolidant

Use epoxy liquid wood consolidant to penetrate and impregnate deteriorated wood sections to reinforce wood fibers that have become softened or absorbent.

3.2.5.2 Epoxy Paste

Use epoxy paste to fill areas where portions of wood are missing such as holes, cracks, gaps, gouges, and other voids. Prime areas to receive epoxy paste patching material with compatible epoxy liquid wood consolidant or a primer recommended by the manufacturer.

3.2.6 Wood Replacement

Replace pieces decayed beyond repair with new pieces that match originals in all respects. Match joinery to existing. Provide muntins consisting of coped mortise and tenon joints. Provide molded members that have mitered or coped joints.

3.2.7 Hardware

Reuse existing hardware, which is in good condition, unless otherwise noted. Strip reused existing hardware of paint down to bare metal.

Install new hardware where original is missing, damaged, or unsuitable for new operation, in accordance with manufacturer's directions to provide a secure and smoothly operating window assembly.

3.2.8 Glazing

Reinstall lights to be reused in their original frames and positions.

Brush rabbeted integral glazing recesses with boiled linseed oil prior to the application of bed glazing compound. Replace broken glass as

SECTION 08 01 52 Page 6 specified in Section 08 81 00 GLAZING.

3.2.9 Operating System

Repair windows with counter-weight systems to original operating function. Reuse original sash weights (and sash chains, if applicable) wherever possible. Replace missing weights and sash cords or chains.

Replace missing or deteriorated sash cords with new cotton-polypropylene cord rated for sash weight. When new weights are required, match the originals in weight. Provide cast iron or square milled steel bar stock replacement weights.

3.2.10 Weatherstripping and Moldings

Install Weatherstripping on all operable windows. Provide weatherstripping consisting of brass, compression or interlocking weather strips designed for permanent sealing under bumper or wiper action.

Provide weatherstripping at the perimeter of each sash including meeting rails and install in accordance with manufacturer's instructions. Submit a 12 inch long sample of each type of weatherstripping required with fasteners. Weatherstripping must be completely concealed when sash is closed. Install moldings in accordance with manufacturer's instructions.

Submit a 12 inch long piece of each molding type required for each window and casing with specified finish.

3.3 PAINTING PREPARATION

Scrape, sand, and feather edges in areas where paint was removed or where existing paint shows crazing, wrinkling, and intercoat peeling. Remove paint to bare wood or first sound paint layer. Clean all parts by brush using bleach and/or trisodium phosphate (TSP) solution, and let dry.

Degloss existing finish. Fill open joints and cracks with epoxy repair materials. Caulk perimeter of fixed sash.

3.4 PAINTING

Prime and paint wood elements in accordance with Section 09 90 00 PAINTS

AND COATINGS.

3.5 REASSEMBLY

After repairs are completed, reassemble the window with all parts tight, true and functioning properly. Wood surfaces must be free of blemishes.

3.6 ADJUSTMENTS

Make final adjustment, for proper operation of ventilating unit, after reassembly. Make adjustments to operating sash or ventilators to assure smooth operation and weathertight performance when locked closed.

3.7 CLEANING

Clean windows on both exterior and interior sides.
