I. System Overview and Products
Siplast Parapro 123 Products
The Parapro 123 Flashing System used with
PMMA-based flashing system designed for use in conjunction
Systems
The Siplast Parapro 123 Flashing System is a liquid-applied,
with SBS-modified bitumen and PMMA-based roofing sys-
tems. The Parapro 123 Flashing System is a layered application consisting of one coat of primer (where required
depending on substrate conditions) and waterproofing layers
reinforced with polyester fleece.
Parapro products include Parapro 123 Flashing Resin and
Parapro Roof Membrane Resin. Pro Products, which are used
with both Parapro Systems and Terapro Waterproofing Sys-
tems, include: Pro Primers, Pro Color Finish, Pro Catalyst, and
Pro aggregates. Pro Primers and Pro Color Finish are collectively referred to as Pro Resins in this Installer’s Guide.
Siplast SBS-Modified Bitumen Roof Membrane
The Parapro 123 Flashing System can be applied directly over
standard Siplast SBS-modified bitumen roof systems that are
applied by torch, Type IV asphalt, or SFT Adhesive. Alterna-
tively, the Parapro 123 Flashing System can be installed between plies of Siplast SBS-modified bitumen Roof Systems
applied by torch, hot asphalt, SFT Adhesive or solvent-based
adhesive. Refer to the application instructions beginning on
page 12 of this guide for step-by-step installation procedures.
Contact the Siplast Technical Department at 1-800-922-8800
for information.
Weather Restrictions
Do not apply any Parapro or Pro Resin products if there is a
threat of precipitation, condensation is present on the substrate or the ambient temperature is within 5°F of the dew
point. Ambient and substrate temperatures affect the application of Siplast Parapro and Pro Resin materials. Ambient and
substrate temperature guidelines and restrictions vary by
product, and are noted in the product sections of this guide.

product shelf life is 6 months from ship date. The shelf life of
resin products will be reduced if the products are stored at

Pro Prep a minimum of 20 minutes drying time after application before continuing. The next application process
should be completed within 60 minutes of cleaning with

suitability as a substrate for waterproofing materials. Prepare by shotblasting or grinding. Contact Siplast for a list
of approved polymer concrete products.
9. Tape all joints between panels and panel edges at all walls,
perimeters, and penetrations using gaffer’s tape before
priming or apply Eternabond® Webseal® after priming.
10. Mopping asphalt residue should be removed from the
primary substrate that will receive the Parapro Flashing
materials.
11. Priming is recommended over raw asphalt if aesthetics is a
concern.
12. While priming of the Paradiene 20 is not required, Pro
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.

All loose granules, dust, and organic debris must be com-

New concrete must be cured a minimum of 28 days in accordance with ACI-308 (or as recommended by the concrete
manufacturer) and meet moisture content guidelines before
the application of the appropriate Pro Primer. New or existing
concrete must be prepared to provide a sound substrate free
from laitance and should be free from materials that may in-
hibit adhesion of the Parapro 123 Flashing System. All spalls
and voids must be repaired and allowed to cure a minimum of
28 days in accordance with ACI-308 (or as recommended by
the concrete manufacturer). Small spalls and voids may be
primed with the appropriate Pro Primer and repaired with Pro
Paste prior to application of the Parapro Flashing Membrane.
Masonry walls should be prepared in the same manner as
concrete substrates. Parapro materials must not be applied
over soft or scaling brick or masonry, faulty mortar joints, or
walls with broken, damaged, or a leaking coping system.
Masonry wall surfaces above the termination of the Parapro
materials should be appropriately treated against moisture
intrusion, and a properly sealed, reglet-anchored counterflash-
ing should be considered. Siplast guarantees exclude from
coverage moisture entry through walls above the Parapro
termination.
Acceptable sheathings include approved cementitious boards,
tion of Parapro flashing materials. Common paper-faced gyp-
sum wall board is not acceptable. Joints between panels must
be covered with 2-inch wide strips of gaffers tape and the
panels/tape must be primed using Pro Primer W prior to application of the Parapro Flashing Membrane. Alternatively, the
panels can be primed followed by application of 2-inch strips
of Eternabond Webseal over the joints. Parapro Flashing
Membrane applied to walls with approved insulation or substrate panels must be adequately counterflashed.
Plywood Sheathing Panels
Plywood should be exterior grade, AC or better. Install panels
with the “A” side to receive the primer. “A” surfaced plywood is
used to eliminate the presence of knots and/or glues, both of
which can contaminate primers. Pressure treated and fire-retardant plywood is typically not produced in a A-grade finish
and is generally wet with chemical treatments. Any such panel
should be tested by Siplast R&D before use to ensure the
chemicals will not affect the primer or primer adhesion. Prior to
application of the Parapro Flashing Membrane, overlay joints
with gaffers tape and prime using Pro Primer W. Alternatively,
panels can be primed using Pro Primer W, including the verti-
cal surfaces at gaps between panels, and joints filled with Pro
Paste and reinforced using a 6-inch (150 mm) wide strip of
Parapro Flashing Resin/Pro Fleece/Parapro Flashing Resin.
Another option is to apply a 4-inch (75 mm) strip of Eternabond Webseal over the joints between primed panels.

Pro Catalyst is available in 0.1 kg (100 gram) premeasured

Whenever possible, pre-measured Pro Catalyst should be
used for mixing. When this is not practical, or small quantities
of resin are required, Pro Catalyst may be field measured using
the following methods:

The most accurate means for field measuring Pro Catalyst is
with a portable, battery-operated scale.

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
