3.1.3
Priming
Prime surfaces to receive fluid-applied waterproofing membrane. Apply
primer as required by membrane manufacturer's printed instructions.
3.2
SPECIAL PRECAUTIONS
Protect waterproofing materials during transport and application. Do not
dilute primers and other materials, unless specifically recommended by
materials manufacturer. Keep containers closed except when removing
contents. Do not mix remains of unlike materials. Thoroughly remove
residual materials before using application equipment for mixing and
transporting materials. Do not permit equipment on the project site that
has residue of materials used on previous projects. Use cleaners only for
cleaning, not for thinning primers or membrane materials. Ensure that
workers and others who walk on cured membrane wear clean, soft-soled shoes
to avoid damaging the waterproofing materials.
3.3
APPLICATION
Over primed surfaces, provide a uniform, wet, monolithic coating of
fluid-applied membrane, 1.5 mm 60 mils thick, plus or minus 0.125 mm 5 mils
by following manufacturer's printed instructions. Apply material by
trowel, squeegee, roller, brush, spray apparatus, or other method
recommended by membrane manufacturer. Check wet film thickness as
specified in paragraph entitled "Film Thickness" and adjust application
rate as necessary to provide a uniform coating of the thickness specified.
Where possible, mark off surface to be coated in equal units to facilitate
proper coverage. At expansion joints, control joints, prepared cracks,
flashing, and terminations, carry membrane over preformed elastomeric sheet
in a uniform 1.5 mm 60 mil thick, plus or minus 0.125 mm 5 mils, wet
thickness to provide a monolithic coating. If membrane cures before next
application, wipe previously applied membrane with a solvent to remove dirt
and dust that could inhibit adhesion of overlapping membrane coat. Use
solvent recommended by the membrane manufacturer, as approved.
3.3.1
Work Sequence
Perform work so that protection board is installed prior to using the
waterproofed surface. Do not permanently install protection board until
the membrane has passed the flood test specified under paragraph entitled
"Flood Test." Move material storage areas as work progresses to prevent
abuse of membrane and overloading of structural deck.
3.3.2
Protection Board
Protect fluid-applied membrane by placing protection board over membrane at
a time recommended by the membrane manufacturer. Protect membrane
application when protection board is not placed immediately. Butt
protection boards together and do not overlap.
3.3.3
Drainage Course
Place drainage course where shown after flood tests are completed and
concrete protection slab or wearing course is ready to be installed.
3.3.4
Insulation
Place insulation of thickness indicated, on top of drainage course just
