The bottom edge of the backer felt should terminate at the bottom edge(base) of the cant. Do not extend the backer felt onto the horizontal membrane surface.Laps in the backer felt should be a minimum of 2”.

C. Cut the BaseFlashing into sections that can be easily handled and installed (6’-8’).Starting just above the top edge of the backer felt, mop the wall, the surface of the backer


felt, and out onto the roof membrane with hot Type IV asphalt. Holding the upper cornersof the BaseFlashing, position its lower horizontal edge on the roof membrane (minimum4” from base of the cant) and lay it into place over the cant strip and up the wall. Thesheet should be “worked-in” to ensure that it is firmly and uniformly bonded. In cool orcold weather, the back of the flashing sheet should also be mopped with the hot bitumen,and shorter lengths of BaseFlashing should be used. Laps in the in the BaseFlashingshould be minimum of 3” and be well sealed.

PART 3 EXECUTION

3.01 EXAMINATION

A. Do not begin application of coatings until substrates have been properly prepared.


1. Including but not limited to primer and texture required for gypsum wall surfaces specified in Section 092116.

B. Verify that surfaces are ready to receive work as instructed by the product manufacturer.

C. Examine surfaces scheduled to be finished prior to commencement of work. Report any condition that maypotentially affect proper application.

D. Test shop-applied primer for compatibility with subsequent cover materials.

E. Measure moisture content of surfaces using an electronic moisture meter. Do not apply finishes unlessmoisture content of surfaces are below the following maximums:

1. Gypsum Wallboard: 12 percent.2. Masonry, Concrete, and Concrete Unit Masonry: 12 percent.3. Interior Wood: 15 percent, measured in accordance with ASTM D 4442.4. Exterior Wood: 15 percent, measured in accordance with ASTM D 4442.

3.02 PREPARATION

A. Clean surfaces thoroughly and correct defects prior to coating application.

B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for thesubstrate under the project conditions.

C. Remove or mask surface appurtenances, including electrical plates, hardware, light fixture trim,escutcheons, and fittings, prior to preparing surfaces or finishing.

D. Seal surfaces that might cause bleed through or staining of topcoat.

E. Remove mildew from impervious surfaces by scrubbing with solution of tetra-sodium phosphate and bleach.Rinse with clean water and allow surface to dry.

F. Concrete and Unit Masonry Surfaces to be Painted: Remove dirt, loose mortar, scale, salt or alkali powder,and other foreign matter. Remove oil and grease with a solution of tri-sodium phosphate; rinse well andallow to dry. Remove stains caused by weathering of corroding metals with a solution of sodiummetasilicate after thoroughly wetting with water. Allow to dry.

G. Gypsum Board Surfaces to be Painted: Fill minor defects with filler compound. Spot prime defects afterrepair.

H. Galvanized Surfaces to be Painted: Remove surface contamination and oils and wash with solvent. Applycoat of etching primer.
