3. Product Description
BASIC USE
Procorª fluid-applied waterproofing mem-
branes are ideal for waterproofing concrete,
masonry and plywood surfaces below grade
and in split slab construction. Typical below-
grade applications include foundation walls,
tunnels and earth sheltered structures. Typical
split slab applications include plaza decks, bal-
conies, pedestrian walkways and parking
decks.
Procor membranes are ideally suited for
interior use conditions where the membrance
will be covered such as floors in mechanical
rooms, laboratories, kitchens, wet rooms and
bathrooms. They also can be used in planters.
Procor fluid-applied waterproofing mem-
branes are especially suited for jobs where the
use of solvents is restricted. They can be used in
new construction and retrofit applications.
Procor is available for both hand and spray
applications.
Procor 10 waterproofing membrane is
intended primarily for horizontal hand appli-
cations. Procor 20 waterproofing membrane is
intended primarily for vertical hand applica-
tions. Procor 75 waterproofing membrane is
intended for all spray applications.
COMPOSITION & MATERIALS
Procor 10, Procor 20 and Procor 75 fluid-applied
waterproofing membranes are 2-part, self-
curing rubber-based materials. The volatile
organic compound (VOC) content of Procor
waterproofing membranes as applied is 75 g/L.
COMPATIBILITY
Procor is not compatible with petroleum sol-
vents, fuels and oils, materials containing
creosote, pentachlorophenol or linseed oil.
Procor membranes are not compatible with
certain types of prefabricated drainage sys-
tems that damage waterproofing mem-
branes when exposed to soil pressures.
LIMITATIONS
Do not specify Procor membranes in areas
where they will be permanently exposed to
sunlight, weather or traffic. If an exposure
period of greater than 30 days is anticipated,
some form of temporary protection should be
used. Do not specify Procor for exposed inte-
rior use.
Apply Procor membranes directly to struc-
tural surfaces. Do not apply Procor mem-
branes over lightweight insulating concrete.
Insulation, if used, must be installed over the
membrane.
Procor membranes are not recommended
for use as a tank or containment structure liner
unless in split slab construction.
In horizontal applications where a minimum
slope of 0.125 in/ft (10.6 mm/m) cannot be
achieved, a 2-coat application of Procor mem-
brane is recommended to achieve a total
thickness of 120 mil (3 mm).

5. Installation
SAFETY, STORAGE & HANDLING
Procor waterproofing membranes, Parts A
and B, should be stored under cover in origi-
nal sealed containers between 40 - 90
degrees F (4 - 32 degrees C). Part A reacts
with water releasing heat. Do not allow Part A
to come in contact with water. Prevent Part B
from freezing during storage. In cool temper-
atures, store the material for several hours at
room temperature to facilitate mixing and
application. The shelf life is 9 months in
unopened containers. Shelf life will be
reduced if stored in temperatures above 90
degrees F (32 degrees C).
Refer to product label and Material Safety
Data Sheet (MSDS) before use. All users should
acquaint themselves with this information
prior to working with the material. Carefully
read detailed precaution statements on the
product labels and MSDS before use, or con-
tact Grace Construction Products.
PREPARATORY WORK
Concrete
All concrete and masonry surfaces must be
smooth, monolithic and free of frost, voids,
spalled areas, loose substrate and sharp pro-
trusions, dirt, oil, grease and debris and must
contain no other contaminants or any visible
coarse aggregate. Repair defects such as
spalled or poorly consolidated areas.
Tie-holes, bugholes, voids and surface irreg-
ularities larger than 1/2" (13 mm) in diameter or
deeper than 1/8" (3 mm), or both, should be
either pretreated with Procor or repaired with
a lean concrete mix of grout. See ASTM
D5295, Preparation of Concrete Surfaces for
Adhered Membrane Waterproofing Systems,
for further details concerning substrate
preparation.
Cracked, pitted, honeycombed or heavily
bugholed surfaces can be filled by spraying
from close in, 10" - 12", but high material usage
will result. Under these circumstances, it may
be more efficient to fill the surface with a
parge coat of lean mortar mix before appli-
cation of the Procor. It is also acceptable to fill
in gaps with a compatible sealant or caulk.

Remove windows, sharp protrusions and
form match lines. Also remove high spots
greater than 1/32" (0.8 mm) in height. On high-
ly porous and rough surfaces, it may be nec-
essary to apply Procor Concrete Sealer or a
scratch coat of Procor to provide a smooth
surface before applying the liquid membrane.
All substrates must be wire-brushed, swept
with a stiff broom or blown off with low pres-
sure air to remove dirt, dust and loose stones.
Poor quality surfaces with excessive laitance
may require shotblasting or pressure washing
to provide a dense, smooth surface free from
contaminants.
Please refer to Tech Letter #2, Inspection
and Repair of Concrete, for more information.
Masonry
Apply a scratch coat of Procor to provide a
smooth surface before applying the liquid
membrane.
Wood/Plywood
Apply Procor membrane over a securely fas-
tened sound surface. To create a smooth sur-
face, ensure that all joints and fasteners are
flush.
Contact Grace Construction Products if the
suitability of the substrate is in question.
Temperature
Hand Application - Apply Procor 10 and 20
membranes at ambient and substrate tempera-
tures above 40 degrees F (4 degrees C). Do not
apply the material if the ambient temperature is
likely to fall below 32 degrees F (0 degrees C)
within one hour of application completion.
Spray Application - In spray applications
using Procor 75, it is possible to work at tem-
peratures below 40 degrees F (4 degrees C)
provided there is no frost or condensation on
the substrate. The minimum temperature for
spray application is 20 degrees F (-7 degrees
C). Refer to Technical Bulletin 13, Spraying
Procor 75 at Low Temperatures, or contact a
Grace Construction Products representative
for cold weather spraying guidelines.
Application to Green Concrete or Damp
Surfaces
Procor may be applied to green (minimum 3
days) concrete or over surfaces that are
damp to the touch. Remove any visible water
prior to application. In green concrete or
damp substrate applications, direct sunlight
may cause the surface temperature to rise
rapidly, drawing moisture from the substrate
and resulting in blisters and pinholes in the
membrane. Under these conditions, it may be
necessary to apply Procor Concrete Sealer or
a scratch coat of Procor before applying the
liquid membrane.
Do not apply Procor waterproofing mem-
branes in wet weather. Once applied, the
membranes will not be affected by light rain
showers.
MIXING
If Procor waterproofing membranes are stored
in cold temperatures, allow the material to
stand at room temperature for several hours to
facilitate mixing and application.
Handmixing (Procor 10 and 20 only): Open
the Part A container and stir or mix for about
15 seconds. Add the en
