[PART 3: EXECUTION]{.underline}

3.1 EXAMINATION:

A. Verification of Conditions: Verify surfaces are solid, free of frozen
matter, loose particles, cracks, pits, rough projections, and foreign
matter detrimental to adhesion and application of damp-proofing. Do not
apply damp-proofing to damp, frozen, dirty, dusty, or deck surfaces
unacceptable to \[applicator.\]

B. Bitumen Membrane: Allow 24 hr drying time and do not backfill against
damp-proofed surfaces until surfaces have been inspected and approved.
See Section 02221 ‑ Excavating, Backfilling and Compacting for
Structures.

3.2 PREPARATION:

A. Surface Preparation:

1\. Clean and prepare surfaces to receive damp-proofing according to the
manufacturer\'s instructions.

2\. Apply mastic to seal penetrations, cracks, honeycomb in substrate.

B. Protection:

1\. Protect finished dampproofing from damage during backfill operations
by adhering protection board with mastic over treated surfaces.

2\. Neatly fit boards around pipes and projections.

3\. Backfill against protection board to prevent injury to membrane.

3.3 APPLICATION:

A. General: Apply dampproofing to exterior face of foundation walls.

B. Prime Coat: Prime surfaces \[according to the manufacturer\'s
instructions.\] \[according to the NCRA ‑ Weatherproofing Manual.\] \[at
a rate of \[[ ]{.underline}\] gal/100 sq ft\]. Permit primer to dry
before applying succeeding coats.

C. Succeeding Coats:

1\. Apply \[hot\] \[cold\] bitumen with \[mop.\] \[roller.\] \[spray.\]

2\. Apply \[one\] \[two\] coats, continuous and uniform at a rate of \[[
]{.underline}\] gal/100 sq ft \[per coat.\]

3\. Apply from \[2\] inches below finish grade elevation to \[top of
footings.\] \[[ ]{.underline}.\]

D. Seals: Seal watertight items projecting through damp-proofing surface
with mastic.
