3.2	PREPARATION
A.	Remove all dirt, trash, debris, grease, oil, water, moisture and other contaminates from the footings and walls which may affect the bond of the membrane to application surface.
B.	Condition of Surface: Any new concrete surfaces shall be wood float finish ACI 301-11.7.3 and comply with ASTM D5295 requirements. All concrete shall have cured for a minimum of 28 days or, alternatively, pass the ASTM D4263 and the NRCA deck dryness tests. All surfaces shall be dry, clean, firm and free from laitance, frost, dust, dirt, oil, unapproved curing compounds or other foreign matter detrimental to the performance of the waterproofing membrane. Contractor shall certify no wax base curing compounds have been used.
C.	Before commencing work, examine all areas and report in writing to Architect any conditions that will adversely affect successful installation. Do not begin work until the conditions have been addressed and corrected. Voids, cracks, holes and other damaged surfaces shall be repaired with materials compatible with waterproofing membrane.
D.	Expansion Joints: Expansion joints shall be sharply formed and free of broken edges, loose aggregate and completely free of preformed joint fillers, sealants or back-up materials to a depth that is at least twice the width of the joint. Chamfer edges of the joint.
E.	Contractor shall verify concrete surfaces are properly cured, dry, and reasonably smooth and in conformance with ASTM D5295 standard guide for concrete surface preparation. Prepare other surfaces according to respective Manufacturer's published instructions. Use cleaning materials and methods necessary to render an acceptable dust- free surface, including oil-free filtered compressed air or high speed power blowers. Protect adjacent areas from damage with tarpaulins or other durable materials.
F.	Temporary protection to installed membrane is required to prevent damage by mechanical gouging, scraping, spilling of oil and solvents or excessive heat.
3.3	INSTALLATION
A.	Install in accordance with manufacturer's instructions, approved submittals, and in proper relationship with adjacent construction.
B.	Surface Conditioner: Each day, prior to application of waterproofing membrane, apply surface conditioner, as a fine spray at a rate of approximately 1 gallon (3.8 L) per 300 to 600 square feet (27.9 to 37.2 square meters). Allow to dry completely tack free. Do not allow primed surface to be contaminated with construction debris or dust barrier. Re-prime and allow to dry as may be required by job conditions.
C.	Application: Units of waterproofing membrane shall be melted in an approved double-jacketed melter under continuous agitation until the material can be drawn free-flowing and lump- free at a temperature of approximately 350 to 400 degrees F (177 to 204 degrees C).

Roll all membrane with a steel hand roller. Install termination bar at top of lower sheets prior to installation of higher sheets.
2.	At the top terminations, press the membrane firmly to the wall with steel roller and secure with a termination bar. Seal all laps and termination bars with a toweling of hot waterproofing membrane before the end of each work day. Deck membrane shall overlap vertical wall membrane by 12 inches (305 mm).
F.	Crack Treatment: At all cracks and construction joints, apply waterproofing membrane with a 6 inch (152 mm) wide strip of flashing over the joint or crack and embed into the warm membrane. Avoid air pockets. Allow assembly to cool. Flashing should be installed before the continuous, unbroken thick film of bitumen and reinforcement felt is applied over the entire application surface and flashing areas in accordance with Part 3 of this Specification.
G.	Expansion Joints: Over expansion joints, up to 2 inches (51 mm) in width with a designed total movement of 50 percent or less, neoprene flashing shall be placed over the joint as shown on the drawings and embedded into a 125 mil (3.12 mm) thick coating of waterproofing membrane. The sheet shall be looped into the joint 1-1/2 times the joint width at maximum opening and extend 8 inches onto the substrate on each side of the joint. The sheet shall be covered and the loop coated with waterproofing membrane. Install 1-1/2 inch (38 mm) foam rod and second sheet of neoprene flashing looped over the foam rod.
