PART 3 EXECUTION
 
3.1
EXAMINATION
A.
Do not begin installation until substrates have been properly prepared.
1.
Substrates shall be inspected and repaired as needed to provide a proper surface to receive waterproofing system.
2.
Verify substrate surface slopes to drain for horizontal waterproofing applications.
3.
Identify incompatible substrates, if any.
B.
Verify substrate openings, curbs, and protrusions through deck/substrate, wood cant strips and reglets are in place and solidly set.
C.
If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2
PREPARATION
A.
Surfaces to be prepared as a substrate for the new waterproofing system as follows:
1.
Determine the condition of the existing structural deck/substrate. All defects in the deck or substrate shall be corrected before new waterproofing work commences. Areas of deteriorated deck/substrate, porous or other affected materials must be removed and replaced with new to match existing.
2.
Prepare flashing substrates as required for application of new waterproofing membrane flashings.
3.
Inspect substrates, and correct defects before application of new waterproofing. Fill all surface voids greater than 1/8 inch wide with an acceptable fill material.
4.
Remove all ponded water, snow, frost and/or ice from the work substrate prior to installing new waterproofing materials.
5.
Final substrate for waterproofing shall be clean, dry, free of loose, spalled or weak material including coatings, mineral aggregate, and flood coat/gravel surfacing, oil, grease, contaminants, abrupt changes in level, waterproofing agents, curing compounds, and free of projections which could damage membrane materials.
B.
On Site Testing: Perform on site testing of cementitious substrate. Determine substrate moisture content throughout the work and record with Daily Inspection Reports or other form of reporting acceptable to the Architect, and Membrane Manufacturer. Do not begin application of waterproofing until acceptable conditions are achieved.
1.
Evaluate surface moisture content by means of an Tramex Concrete Moisture Encounter Meter. A surface moisture content of under 5 percent is required to allow for proper primer penetration into the substrate.
2.
Frothing, bubbling, or pinholes within the primer indicates excessive moisture content within the substrate. Blistering of membrane may result from excessive substrate moisture. Primer application during late afternoon/early evening will reduce vapor pressure within the substrate and may alleviate these conditions.
3.
Continued frothing, bubbling, or pinholes indicates excessive moisture content that requires more substantial measures. Evaluate substrate moisture content by means of relative humidity (RH) probes in accordance with ASTM F 2170. Relative moisture content of 75 percent or greater indicates the need for more extensive substrate priming and sealing. Contact Membrane Manufacturer for recommendations.
C.
Bond Strength to Substrate: Conduct random tests to determine tensile bond strength of membrane to substrate at the job site using an Elcometer Adhesion Tester Model 106 or similar device, or by the performance of a manual pull test. Perform tests at the beginning of the Work, and at intervals as required to assure specified adhesion with a minimum of 3 tests per 5000 SF area to be waterproofed. Smaller areas shall receive a minimum of 3 tests. Submit test results to the Architect promptly as they are completed. Notify the Architect immediately in the event the test results are below specified values.
1.
Tensile bond strength of membrane to substrate must be greater than or equal to 150 psi (1.0 N/mm2), as determined by use of an adhesion tester.
2.
Adequate surface preparation will be indicated by 135 degree peel bond strength of membrane to substrate such that cohesive failure of substrate or membrane occurs before adhesive failure of membrane/ substrate interface.
3.
In the event the bond strengths are less than the minimum specified, additional substrate preparation and testing is required. Repeat testing to verify suitability of substrate preparation.
 
** NOTE TO SPECIFIER ** Select required substrate preparation method(s) from the following paragraphs and delete those that are not applicable.

Do not thin primer. Determine required primer coverage for each substrate material/condition and apply in strict accordance with written instructions of Membrane Manufacturer.
E.
Application:
1.
Roll or brush primer evenly onto the surface to fully saturate the substrate in one application. Do not allow primer to pond or collect in low areas. Follow manufacturer's recommended application rates to ensure that a thin layer of cured primer remains on the substrate surface.
2.
Apply primer only up to the edge of the membrane flashing terminations. Primer application past the membrane terminations requires surfacing with an approved material.
3.
For EP/EP5 primer applications over cementitious substrates where protection from substrate wetness is required, apply primer coat at a heavier application rate until pore saturation is achieved.
4.
For all EP/EP5 primer applications, apply kiln-dried sand into final coat of EP/EP5 primer while still wet at the rate of 50 lbs. per 100 square feet.
5.
Allow standard primers to cure for a minimum of 12 hours before membrane application. Allow quick-dry primers to cure for a minimum of 4 hours before membrane application. Membrane must be applied to primer only when completely dry and without tack.
6.
Exposure of the primer in excess of 8 days or premature exposure to moisture may require removal and application of new primer. Do not apply new primer over exposed primer older than 8 days, primer prematurely exposed to moisture, or primer used as temporary waterproofing, unless approved in writing by the Membrane Manufacturer.
3.7
MEMBRANE APPLICATION
A.
General:
1.
Apply the waterproofing membrane immediately following full curing of the primer in order to obtain the best bond between primer and membrane.
2.

3.
Primed substrate surface shall be dry, with any remaining dust or loose particles removed using clean, dry, oil-free compressed air, industrial vacuum, cloth-wipe or a combination.
4.
Protect all areas where membrane has been installed. Do not work off installed membrane during application of remaining work before 48 hours of curing. Movement of materials and equipment across installed membrane is not acceptable. If movement is necessary, provide complete protection of affected areas.

Apply mixed resin to the prepared surface at the manufacturer's recommended application rate. Resin should be rolled or brushed liberally and evenly onto the surface using a broad, even stroke. Cover one working area at a time, between 15 - 20 SF (1.4 - 1.9 m2).
2.
Roll out dry polyester fleece onto the liquid resin mix, making sure the SMOOTH SIDE IS FACING UP (natural unrolling procedure), avoiding any folds and wrinkles. Fleece will begin to rapidly saturate with the liquid resin mix. Use a medium nap roller or brush to work the resin into the fleece, saturating from the bottom up, and eliminating air bubbles, wrinkles, etc. Appearance of the saturated fleece should be light opaque amber with no white spots. White spots are indications of unsaturated fleece or lack of adhesion. It is important to correct these faults before the resin cures.
3.
Apply additional liquid resin mix on top of fleece at the manufacturer's recommended application rate to finish the saturation of the fleece. Roll this final coating into the fleece, which will result in a glossy appearance. The fleece can only hold so much resin and all excess should be rolled forward to the unsaturated fleece, eliminating ponding or excessive build-up of the resin. The correct amount of resin will leave no whiteness in fleece and there will be a slightly fibrous surface texture. Final resin coating should be smooth and uniform.
4.
Approximately 2/3 of the total resin should be applied to the substrate below the fleece reinforcement, and 1/3 of the total resin should be applied over the fleece reinforcement.
5.
Prevent contact between mixed/unmixed resin and new/existing membrane. If any unmixed resin contacts membrane surface remove immediately and clean thoroughly with a cloth rag.
6.
At all fleece seams, allow a 2 inches (5 cm) overlap for all side joints and a 4 inches (10 cm) overlap for all end joints.
7.
At membrane tie-offs, clean in-place membrane with MEK (methyl ethyl ketone) solvent or acetone once resin has cured. Allow solvents to fully evaporate before application of new resin.
