PART	EXECUTION

EXAMINATION

Do not begin installation until substrates have been properly constructed and prepared.

If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.

Examine substrates and conditions, with Applicator present, for compliance with manufacturer's requirements for surface treatments, shop-primed surfaces, maximum moisture content, and other conditions affecting performance of the Work.

Begin coating only when moisture content of wood substrate is 12 percent or less when measured with an electronic moisture meter.

Begin coating no sooner than 28 days after substrate is constructed and is visually dry on both sides.

Verify suitability of substrates, including surface conditions, and compatibility with existing finishes and primers.

Begin coating application only after unsatisfactory conditions have been corrected and surfaces are dry.

Inspection:

The independent testing agency will ensure that preparation of substrate is in accordance with manufacturer's recommendations.

The testing agency will randomly obtain and test samples during application to verify that wet film thickness of the intumescent coating complies with requirements of this section.

Work not in compliance will be rejected and shall immediately be brought into compliance by the applicator.

PREPARATION

Comply with manufacturer's written instructions applicable to substrates and coating systems indicated.

Remove hardware and hardware accessories, plates, machined surfaces, light fixtures, and similar items already installed that are not to be coated. If removal is impractical or impossible because of size or weight of item, provide surface-applied protection before surface preparation and coating.

After completing coating operations, use workers skilled in the trades involved to reinstall items that were removed. Remove surface-applied protection if any.

Clean substrates of substances, including dirt, oil, grease, and incompatible paints and encapsulants, that could impair bond of coatings. Do not coat surfaces if surface moisture content or alkalinity exceeds that permitted in manufacturer's written instructions.

Remove incompatible primers and reprime substrate with compatible primers as required to produce coating systems indicated.

Perform cleaning and coating application so dust and other contaminants from cleaning process will not fall on wet, newly coated surfaces.

INSTALLATION

Install in accordance with manufacturer's instructions, approved submittals, and in proper relationship with adjacent construction.

General: Apply intumescent paints according to manufacturer's written instructions and to comply with requirements for fire-retardant coating classification.

Use equipment and techniques best suited for substrate and type of material being applied.

Coat surfaces behind movable items the same as similar exposed surfaces.

Apply each coat separately according to manufacturer's written instructions.

Apply coatings to prepared surfaces as soon as practical after preparation and before subsequent surface soiling or deterioration.

Apply coatings to produce surface films without cloudiness, spotting, holidays, laps, brush marks, roller tracking, runs, sags, ropiness, or other surface imperfections. Cut in sharp lines and color breaks.

Pigmented Finishes: If undercoats or other conditions show through pigmented topcoat/overcoat, apply additional coats until cured film has a uniform paint finish, color, and appearance.

FIELD QUALITY CONTROL

Field Inspection: Coordinate field inspection in accordance with appropriate sections in Division 01.

Manufacturer's Services: Coordinate manufacturer's services in accordance with appropriate sections in Division 01.

CLEANING AND PROTECTION

At end of each workday, remove rubbish, empty cans, rags, and other discarded materials from Project site.

After completing coating application, clean spattered surfaces. Remove spattered coatings by washing, scraping, or other methods. Do not scratch or damage adjacent finished surfaces.

Protect work of other trades against damage from coating application. Correct damage to work of other trades by cleaning, repairing, replacing, and refinishing, as approved by Architect, and leave in an undamaged condition.

At completion of construction activities, touch up and restore damaged or defaced coated surfaces.
