Maintain surfaces to be waterproofed/lined and surrounding air temperature at not less than 40oF (5oC)
for at least 48 hours before, during and after application of waterproofing.
Do not apply materials to frozen or frost-filled surfaces.
Exercise caution when temperatures exceed 86oF (30oC). It may be necessary to apply
waterproofing/lining during times when the sun is not at its strongest (i.e. early morning, evening or

PART 3 - EXECUTION
Examine substrates and adjoining construction, and conditions under which Work is to be installed.
Do not proceed with Work until unsatisfactory conditions are corrected.
Verify the following substrate conditions before application of waterproof lining:
That substrate condition is satisfactory and in accordance with manufacturer's instructions.
That concrete surfaces have open pores and wood float finish on horizontal surfaces.
That concrete surfaces are free of voids, spalled areas, loose aggregate and sharp protrusions,
and with no coarse aggregate visible.
That curing compounds or surface hardeners incompatible with waterproof lining have not
been used on concrete.
Protect adjacent surfaces not designated to receive waterproof lining.
Remove remaining concrete fins and projections, and general surface dirt.
Remove grease, oil and other contaminants. Use high-pressure water blasting, wet or dry
sand blasting, or other methods recommended by waterproofing manufacturer to produce
surfaces suitable for application of waterproofing.
Follow manufacturer's instructions to clean and prepare surfaces.
Repair cracks, honeycombs, unsound concrete and weak mortar joints.
Roughen form tie holes.
Rinse surfaces to be lined/waterproofed several times so that the concrete is thoroughly saturated.
Surfaces shall be moist but not wet when waterproofing system is applied. Remove any surface water
on horizontal surfaces.
Mix waterproof lining material in proportions recommended by manufacturer.
Apply waterproof lining material in quantities as per manufacturer's specifications and
Floor/wall and corner joints:
Install (rounded) coves 2" x 2" (5 cm x 5 cm) with patching compound in mortar
consistency. Leave rough surface finish for subsequent waterproof lining material to bond.
Horizontal and vertical surfaces - Damp proofing:
Apply 1st coat of waterproof lining material at 40 mils (1.0 mm) thickness (145 SF/50 lb
(13.6 m2/22.7 kg) bag). Apply by masonry brush, steel trowel or appropriate compressed-air
spray equipment. Back-trowel application to uniform thickness if applied with spray
Apply 2nd coat of waterproof lining material at 20 mils (0.5 mm) thickness (295 SF/50 lb
(27.3 m2/22.7 kg) bag) after 1st coat has sufficiently hardened (approximately 2 to 4 hrs) to
total 60 mils = 1/16" (1.5 mm) wet film thickness. Apply by masonry brush, steel trowel or
appropriate air spray equipment. Surface finish shall be troweled smooth, or dense, glazed
appearance if sprayed, showing little indentations from air pressure (orange skin).
Horizontal and vertical surfaces – Waterproofing (subject to hydrostatic pressure):
Apply 1st coat of waterproof lining material at 50 mils (1.25 mm) thickness (120 SF/50 lb
(11.2 m2/22.7 kg) bag). Apply by steel trowel or appropriate compressed-air spray
equipment. Back-trowel application to uniform thickness if applied with spray equipment.
At cleaned and prepared faulty construction joints, cracks, form tie, nail and bug holes, fill
voids with patching compound in mortar consistency flush to surface. Leave rough surface
finish for subsequent waterproofing material to bond.
Apply 2nd coat of waterproof lining material at 50 mils (1.25 mm) thickness (120 SF/50 lb
(11.2 m2/22.7 kg) bag) after 1st coat has sufficiently hardened (approximately 2 to 4 hrs) to
total 100 mils = 1/10" (2.5 mm) wet film thickness. Apply by steel trowel or appropriate air
spray equipment. Surface finish shall be troweled smooth, or dense, glazed appearance if
sprayed, showing little indentations from air pressure (orange skin).
Protect exposed waterproofed/lined surfaces from premature drying out with polyethylene sheeting.
Do not use burlap as this may stain the white surface.
Moisture cure exposed waterproofed/lined surfaces as per manufacturer's instructions.
Remove left over materials and any foreign material resulting from the work from the site.
Clean adjacent surfaces and materials.
