PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly constructed and prepared.
B.	If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.
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: New concrete surfaces shall provide an acceptable finish and have cured for a minimum of 48 hrs. The General Contractor shall certify no wax base or stearate based curing compounds have been used. All form release agents must be approved in writing prior to application. All concrete surfaces shall comply with ASTM D5295 standard preparation guide.
1.	Horizontal concrete surfaces shall comply with ACI 301-11.7.3.
C.	Existing concrete surfaces shall be examined for any defects or failure to meet ASTM D5295 standard. All surfaces shall be free from laitance, grease, oil, unapproved curing compounds, bug holes, air holes, and honeycombs or other foreign matter detrimental to performance of the waterproofing membrane. Contractor shall certify no wax base or stearate based curing compounds have been used.
D.	Voids, cracks, holes and other damaged surfaces shall be repaired with compatible materials.
E.	Before commencing work, examine all areas and report in writing to Architect and manufacturer any conditions that will adversely affect successful installation. Do not begin work until the conditions have been addressed and corrected.
F.	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.
1.	Chamfer edges of the joint.
2.	For horizontal applications, curb expansion joints at each side of the joint, either by integrally forming with the slab or securely fastening sulfate treated wood strips to deck.
3.3	MEMBRANE INSTALLATION
A.	Install in accordance with manufacturer's instructions, approved submittals, and in proper relationship with adjacent construction.
B.	Horizontal Application:
1.	Apply 15-20 mils of Black Pearl Primer Adhesive with a non-serrated straight edge squeegee at the rate of 45 sq. ft./gal. Allow it to dry to a tacky condition (approximately 20 minutes) before installing the Black Pearl Sheet Membrane. Adhesive must extend 1 inch beyond the sheet.
2.	Rub the sheet into the Black Pearl Primer Adhesive with a stiff broom, squeegee, hand garden roller, or similar method.
3.	Lap all edge seams a minimum of 3 inches. Stagger all end laps a minimum of 6 inches. Ensure that total contact with the substrate is maintained. Any membrane "bridging" is unacceptable and will come back to haunt you the installer. Coat the top of the first ply with 15-20 mils of Black Pearl Primer Adhesive at the rate of 45 sq. ft./gal. Allow to dry to tack state. Smoothly embed the second ply, offsetting the side laps of the first ply by half a sheet's width. Any "Fishmouths" or wrinkles in the fabric need to be cut out and detailed.
4.	If additional plies are specified, repeat the same procedure. With multiple ply application, check the adhesion of each ply by applying hand pressure to the sheet. If the sheet moves, delay the next ply application until the underlying sheet has set. 
5.	When all specified plies are installed, it is time to run the flood test (ASTM D-5957), or EVM survey (ASTM D-7877). If any leakage or voids are detected, repair the suspect area and retest until there is no leakage of any kind.
6.	When testing is complete, uniformly coat the final sheet with 15-20 mils of Black Pearl Primer Adhesive at the rate of 45 sq. ft./gal. If specified, install a Ram Protection Course directly into the top coat of Black Pearl Primer Adhesive, starting at the low points. Install any additional overburden such as aeration mats, root barriers, concrete pavers, stone ballast, and similar components in accordance with plans and specifications.
7.	When installing the membrane rub the membrane into place with stiff brooms or a squeegee. Total contact with all substrates is required. No bridging or unattached membrane will be accepted.
8.	Install second layer of membrane in a primer and adhesive coating applied at the rate of 1.0 gallon (3.8 L) per 80 square feet (7.4 square meters), after allowing the primer and adhesive to reach a tacky state. Broom or squeegee in place. Offset the side laps from the first ply by half a sheet width and end laps by 6 inches.
C.	Vertical Application:
1.	Footer Detail: Install 20 mils of the Black Pearl Primer Adhesive into the horizontal-to-vertical junction a minimum of 7 inches on the vertical surface and as far a possible onto the horizontal, leaving room for the termination bar. Install the Black Pearl Sheet Membrane a minimum of 6 inches onto the horizontal-to-vertical junction. Repeat the previous step with 20 mils of Black Pearl Primer Adhesive. Then install the complete system over the detailed area. All other detailing follows the installation guidelines for horizontal applications.
2.	Vertical Surfaces: For applications on vertical surfaces, the Black Pearl Sheet Membrane is to be applied in vertical strips and terminated at grade. Apply Black Pearl Primer Adhesive at a rate of 45 sq. ft./gal. Pre-cut sheets of the Black Pearl Sheet Membrane to workable lengths (typically about 5 to 7 feet). Allow Black Pearl Primer Adhesive to dry to a tacky state, then embed the sheets smoothly into the coating, ensuring that they fully adhere to the vertical substrate. Side laps shall be maintained at 3 inches. The bottom of the sheet shall start at the corner of the previously applied base flashing and run up the vertical substrate to termination of the sheet. Ensure that the top edge of the sheet is sealed tight to the vertical substrate using either Black Pearl Primer-Adhesive or Ram Mastic. The succeeding plies on vertical substrates should overlap the lower application plies by 4 inches.
3.	Multiple plies shall be installed in the same manner as the first ply with offset side laps. For multiple ply applications, check the adhesion set-up of each ply by applying hand pressure to the sheet and exerting sideway pressure. If the sheet moves, delay installation of the next ply until the underlying plies are firmly set.
4.	Where required, apply 20 mils of Black Pearl Primer Adhesive at a rate of 45 sq. ft./gal at the top edge of the topmost lift. Embed a sealing strip of Black Pearl Sheet Membrane 8 to 9 inches wide, cut lengthwise from the sheet, directly into the coating with a handheld squeegee. For specified above-ground applications, install termination bars at the top of the membrane, fastened 8 inches on centers.
5.	Inspection and approval of all waterproofing membrane installations shall occur before application of any protection, insulation board or other overburden. All warranted installations must be inspected and accepted by the Barrett Company before any overburden installation can occur. Protection courses for vertical substrates are recommended to be 1-inch thick and 1-pound minimum density expanded or extruded polystyrene, made or cut into 2 feet by 4 feet wide sheets and adhered with 20 mils of Black Pearl Primer- Adhesive at a rate of 45 sq. ft./gal. All protection course insulation shall be laid up in brick pattern.
