I. System Overview and Products
System Overview
The Parapro Roof Membrane System is a liquid-applied,
PMMA resin-based system designed to provide watertight
protection on low slope and sloped applications. Parapro Roof
Membrane is used in conjunction with Parapro 123 Flashing.
The Parapro Roof Membrane System is a layered application
consisting of one coat of primer (where required depending on
substrate conditions), and waterproofing layers reinforced with
polyester fleece fabric.

of precipitation, condensation is present on the sub-
strate or the ambient temperature is within 5ºF of the
dew point. Ambient and substrate temperatures affect
the application of Siplast Parapro and Pro materials.
Ambient and substrate temperature guidelines and re-

New Concrete Pours
The mix design for new concrete pours should be submitted
to Siplast for review prior to placement. New concrete must
be allowed to hydrate for a minimum of 28 days in accordance
with American Concrete Institute (ACI) Bulletin 308 – Guide to
Curing Concrete, in addition to being below the maximum
moisture content. Concrete should not utilize curing agents,
penetrating release agents, or be treated with waterproofing
materials as these materials can affect primer penetration
and/or adhesion.
New concrete pours may require an extended exposure time
before an acceptable moisture content is reached. To prevent
delays in system installation, the use of an epoxy-based moisture mitigation system should be considered when the mois-
ture content is expected to be above the published maximum
at the time of waterproofing application.

using the ASTM F 1869 test. New test methods have also
been developed for measuring relative humidity over a period

plywood manufacturer’s specifications to minimize the potential for rupture at joints. Plywood panels should be fastened
with corrosion resistant screws using a spacing of not greater
than 6-inches o.c. along panel edges and 12-inches o.c. over
intermediate supports.
Plywood Joint Treatment
Following panel securement, prime panels using Pro Primer W,
including the vertical surfaces at gaps between panels, and
allow to cure. Ensure that the Pro Primer W does not pool in
the joints. Fill joints with Pro Paste and allow to cure. Reinforce the joints using a 6-inch (150 mm) wide strip of Pro
Fleece and Parapro Flashing Resin.
Pre-cast Hollow Core Slabs
or Pre-cast Concrete
Pre-cast hollow core slabs or pre-cast concrete should be dry,
fully cured, clean, and free of imperfections. Slabs should be
securely fastened to the sub frame to prevent movement or
sagging, and should be set level with all joints aligned and
closely butted to provide a smooth, even surface. Using ZonoPatch Patching Compound, grout all joints between uneven
slabs to a slope not to exceed 18-inch per foot on the low
member. For asphalt applications, prime the deck surface with
PA-1125 Primer or PA-917 LS Primer at the rate of 1 gallon
per 100 square feet; keep the primer back 4 inches from
joints. Cover all of the joints with an 8-inch wide strip of
Parabase Plus or Parabase, adhered on one side only with
PA-1021 Plastic Cement. Pre-cast hollow core slabs or pre-
cast concrete decks must be covered by a lightweight insulating concrete fill or an acceptable rigid roof insulation.
Prestressed T or Double T Sections
Prestressed T or Double T sections shall be dry, fully cured,
clean, and free from excessive camber or “set.” Prestressed
sections should be securely anchored against uplift and lateral
movement. Welding plates should be positioned next to the
edge and on the top surface of the member for mid-span securement. Camber differential resulting in offset edges in excess of 14-inch should be corrected with Zono-Patch
Patching Compound prior to the application of insulation and
roofing. Using Zono-Patch, grout all joints between uneven
units to a slope not to exceed 18-inch per foot on the low
member. For asphalt applications, prime the deck surface with
PA-1125 Primer or PA-917 LS Primer at the rate of 1 gallon
per 100 square feet; keep the primer back 4 inches from the
joints. Cover all of the joints with an 8-inch wide strip of
Parabase Plus or Parabase, adhered on one side only with

Steel
Steel roof decks should be constructed in accordance with the
FM Approvals structural requirements listed in the current Fac-
tory Mutual Loss Prevention Data Sheet 1-29. Steel roof decks
should be 22-gauge minimum, and factory galvanized or factory coated with aluminum zinc alloy for corrosion protection.
When specifying galvanized protection, the designer should
decks.
Rigid Roof Insulation
Rigid roof insulation should be kept dry at all times. Edges of
the insulation panels should be butted without forcing, and cut
to fit neatly against adjoining surfaces. The insulation layer
should present a smooth surface to accept the roof mem-
brane. No more insulation should be installed than can be covered in the same day. Insulation panels should be installed
strictly according to the insulation manufacturer’s recommendations and FM Approvals requirements (if applicable). Im-
properly attached insulation can result in roof blow-offs. Siplast
will not be responsible for (and the standard Siplast guarantee
does not include) roof blow-offs due to loss of adhesion of the
insulation layer or performance failure of the insulation itself.
Polyisocyanurates and other materials used as a roofing substrate must be specifically approved by Siplast prior to use,
and a coverboard is required over all polyisocyanurate panels
prior to installation of the Parapro Roof Membrane System.
When insulation panels are applied with hot asphalt over
sloped roof decks, insulation stops may be required. Consult
with the insulation manufacturer regarding requirements for,
and the construction and spacing of, insulation stops.

Re-cover
Because Siplast materials are light in weight, they are espe-
cially suitable and widely used for re-cover applications. Each
re-cover application is unique and should be considered individually. However, certain requirements and procedures are
necessary in the general consideration of any project.
It should be noted that certain design considerations (such as
the use or construction of vapor retarders and the addition
and positioning of expansion joints as necessary, etc.) are the
responsibility of the architect, engineer, or owner and, as
such, are not part of this section.
Although the following criteria are not all inclusive, they do, if
met and used in conjunction with the applicable Siplast specification and details, indicate an appropriate situation for the
consideration of re-cover with Siplast materials.
Siplast recommends the use of analytical tools such as non-
destructive moisture survey methods as well as test cuts and
any other evaluation methods available to ascertain existing
surfaces. (3) Remove and discard all of the base flashings,
and any metal incorporated into the roof system (i.e. gravel
stops, vent stack jacks, drain leads, etc). Bring these areas
back to level using compatible materials. (4) Existing perimeter
nailers should be carefully inspected for proper securement,
and be anchored to the structural deck or supporting mem-
bers as required to meet building code regulations and appropriate uplift approvals. Install new wood nailers where
necessary due to deterioration or inadequate securement, or
when required to bring the nailer to the proper height. (5) Remove all of the existing counterflashing and determine
whether it is in a reusable condition. Lifting of the existing
counterflashing in good condition is acceptable only if it can
be returned to its original position without deformation that
would affect its performance. (6) Except in those cases where
the new assembly will be mechanically attached to the deck,
the existing assembly should be resecured as necessary to
meet all local code and insurance wind uplift requirements.
In most cases, the old roof assembly should be separated
from the new Siplast materials with a product and installation
procedure appropriate for the existing deck, roof system, and
surfacing. Where possible, it is preferable that the separating
materials be mechanically attached using fasteners designed
for that purpose. Please contact your Siplast representative
for recommendations tailored to meet your particular re-cover
conditions.

General Substrate Preparation
This thorough inspection of the existing roof conditions must

be made to determine that: (1) the deck is structurally sound,
(2) the deck is able to take the added weight of the new as-

isting assembly has been specifically ascertained, (5) mini-
mum 8-inch flashing heights will exist at curbs, walls, etc, and
(6) the new assembly will provide proper drainage.
Preparation of the existing assembly is extremely important to
the ultimate performance of the new membrane. The following
preparatory procedures should be followed: (1) Power-broom

adhesion of the catalyzed primer and/or resin to the sub-
strate. Some surfaces may require shotblasting, scarification
followed by shotblasting, or grinding to achieve a suitable
substrate.

4. Wipe down thoroughly with Pro Prep prior to coating.
Allow Pro Prep a minimum of 20 minutes drying time after
application before continuing. The next application rocess
should be completed within 60 minutes of cleaning with
Pro Prep.
5. See substrate preparation and repair guidelines on page
5.
6. Grind surface to remove glaze. Tiles must be fully bonded
to a sound foundation. No moisture should be present
beneath tiles.
7. All paint coverings and coatings must be removed.
8. Refer to polymer concrete manufacturer’s requirements for
suitability as a substrate for waterproofing materials.
Prepare by shotblasting or grinding. Contact Siplast for
uns at side laps.
Primer R can be applied to maintain a consistent aesthetic
appearance. Pro Primer R cannot be used over concrete
or masonry and is not intended for use over asphalt
contaminated roofing or flashing substrates.
13. A peel test is recommended to ensure that adhesion is
adequate.
Substrate Preparation and
Repair Masonry Walls
Masonry walls should be prepared in the same manner as
concrete substrates (see page 5). Parapro materials must not
be applied over soft or scaling brick or masonry, faulty mortar
joints, or walls with broken, damaged or leaking coping. Laitance must be completely removed by grinding. The Siplast

used, and varies with the ambient temperature and type of
resin (primer, paste, base, flashing, or color finish). Pro Catalyst is available in 0.1-kg (100 gram) pre-measured bags to
simplify the catalyzing and mixing of Pro Resins. Whenever
possible, pre-measured bags of Pro Catalyst should be used
for mixing. See pages 12-13 for mixing ratios. The amount of
Pro Catalyst added to Parapro and Pro Resins must not be
less than 2%. If resin mixed with the minimum required cata-
lyst of 2% does not offer sufficient pot life, the resin temperature may be too high.

Priming with catalyzed Pro Primer R Resin is recommended
prior to application of Parapro Roof Membrane Systems over
asphaltic substrates. For specific priming requirements, refer
to the substrate preparation chart on page 10 of this guide.
Pro Primer T, Pro Primer W, and Pro Primer R may be applied
when the ambient and substrate temperatures are between
32°F (0°C) and 95°F (35°C). The resin itself should be within
storage temperature guidelines at the time of catalyzation to
ensure that the product maintains a workable pot life. Discontinue membrane application when the ambient and/or substrate temperature exceeds 95°F (35°C). In warm
temperatures, the substrate should be shaded for a sufficient
period of time both prior to and during application, as necessary, to maintain substrate temperatures below 95ºF (35ºC).

Parapro Flashing Resin Pot Life
Parapro Flashing Resin pot life is approximately 15 minutes
when the catalyzed liquid is at 68°F (20°C). Pot life will be reduced if the resin is at higher temperatures. Pot life can be
maximized by storing product under controlled conditions and
ensuring that the liquid resin is at the low range of minimum
storage temperature during/following catalyzation and prior to
application.
All flashing/penetration applications installed in conjunction
with the Parapro Roof System should be completed prior to
the liquid field membrane application.

XI. Parapro Roof Membrane Resin
General Application Guidelines
Parapro Roof Membrane Resin, when catalyzed, forms the
waterproofing layer in the system.
Parapro Roof Membrane Resin is available in two formulations:
Summer Grade and Winter Grade. Care should be taken to
ensure the correct formulation of Parapro Roof Membrane
Resin (Summer Grade or Winter Grade) is chosen for the ap-
even waterproofing layer of catalyzed Parapro Roof Membrane
Resin is applied to the substrate with a roller. Pro Fleece reinforcement is worked into the wet, catalyzed Parapro Roof

After priming with the appropriate Pro Primer (if applicable), an
product maintains a workable pot life. The substrate temperature should be between 23°F (-5°C) and 77°F (25°C).
Parapro Roof Resin pot life is approximately 15 minutes when
the catalyzed liquid is at 68°F (20°C). Pot life will be reduced if
the resin is at higher temperatures. Pot life can be maximized
by storing product under controlled conditions and ensuring
that the liquid resin is at the low range of minimum storage
temperature during/following catalyzation and prior to application.

XIV. Parapro Roof Membrane System Applied over Paradiene 20 P Series Products
NOTE: Flashing membrane application is typically accomplished prior to application of the Parapro field membrane. See the Parapro
123 Flashing System Installer’s Guide for information regarding detailed application of flashing materials.
Preparation of Existing
Parapro Surfaces
Using Pro Prep, wipe down thoroughly all horizontal areas of the Parapro Flashing Membrane
which will receive an overlap of the Parapro
Roof Membrane. Allow Pro Prep a minimum 20
minutes drying time after application before
continuing.
Note: Certain substrates require priming with
Pro Primer before application of Parapro Roof
Membrane Resin. Refer to the Substrate
Preparation Chart in the Parapro Roof Membrane Installer’s Guide for priming requirements. Apply a base coat of catalyzed Parapro
Roof Membrane Resin at a minimum consumption rate of 0.19 kg/sf - 18.6 kg/square
(2.0 kg/m2) using an approved roller. Due to the

varying porosity of different substrates, additional Parapro Roof Membrane Resin may be
required to ensure proper coverage and fleece
embedment.
Use a roller to embed the fleece in the resin
and remove trapped air. Lap fleece layers a
minimum of 2 inches, and apply an additional
coat of catalyzed Parapro Roof Membrane
Resin between layers of overlapping fleece.
Apply a top coat of catalyzed Parapro Roof
Membrane Resin at a minimum consumption
rate of 0.12 kg/sf -12.1 kg/square (1.3 kg/m2)
using an approved roller immediately following
embedment of the Pro Fleece to ensure full
saturation of the fleece. Allow to cure for
2 hours prior to application of any optional
color finishes or anti-skid surfacings. The completed Parapro Roof Membrane can be exposed to foot traffic after a 2-hour cure time.
