4 Rolls of Putty Tape (1/8" Thick x 3/4" W x 30' L)
2 Gallon of Class A Customs Acrylic Water Based Adhesive
Membrane Length / Width It is recommended to get a length that is longer / wider than your unit due to possible curve of the roof, raised or lowered areas, removing the excess is much better than not having enough.
Class A Customs Warranty Registration Must Be Completed Within 30 Days for warranty to be valid.
PVC Membrane
RV USE ONLY
Color White: Color is same throughout substrate (white on both sides), can
be applied either side facing down.
Thickness: 0.90 millimeter thickness
All of Class A Customs Membranes are been tested by a 3rd party company for quality and UV resistance: 1,000-hour accelerated weathering (ASTM G155 xenon arc) and color fade (ASTM D2244) test.
INSTALLATION INSTRUCTIONS
As soon as possible, while on top of clean unit remove membrane from box, do not drag over edge of unit.
• Do Not allow membrane to sit boxed, use
as soon as possible.
• Do Not allow membrane to touch ground, dirty surfaces,
sharp objects, or surfaces, including lifted screw head and edges.
• Do Not drag the membrane as this can cause punctures and
tears, this is not covered under warranty.
• Membrane can be glued either side down. Single-Ply
membranes are the same color throughout.
Membrane must be installed onto clean wooden surface, do
not install on top of existing membrane, glue, etc.
• Router all vent and accessory openings. Sand all openings,
seams, and edges to a smooth finish. Remove all debris off roof with air hose.
• Apply seam tape (2” minimum width) evenly onto roof and
sidewall to cover any sharp edges, it is required that seam tape be used to
avoid edge splits. (We do not provide seam tape due to different sized needed)
• Make sure all screw heads and surfaces are smooth and level
throughout, raised screws will puncture membrane and is not covered under
warranty.
Membrane Installation
1. Cut the membrane to fit roof length with an excess of at
least 6” front and rear.
2. “Bed Sheet” the membrane. That is, fold it in half so half
of the roof is exposed.
3. Apply adhesive in a wet film thickness of 8-10 mils with a
short-napped paint roller to the exposed half of the roof decking, brush can be
used but is more difficult. (1 gal. will cover approximately 160-200 sq ft.
best when applied in air temperatures over 50 deg F (10 deg C).
4. Lay the roof membrane over the wet adhesive, the membrane
needs to be adjusted both in width (side to side) and length (front to rear) to
ensure the membrane is as flat as possible before the squeegee process. Let
surplus material drape over the side of the unit for perimeter finishing.
5. Remove all air pockets and wrinkles with a squeegee (gray
neoprene head will not streak) or linoleum roller; press firmly working from
the center outward toward the edges, do not be on the roof during this time.
All wrinkles must be removed at this point for a quality installation. The roof
will tighten and conform as the adhesive cures removing creases, be sure to
complete roof securing steps before allowing roof to dry.
6. Repeat steps 2 – 5 for remaining half of roof.
Roof Securing Steps
7. Apply putty/butyl tape to the backside of the roof-edge
molding. Then while holding the bar, draw surplus material tight with a
downward pull, but do not stretch the membrane. Drive screws through molding,
membrane, and roof framing members. For best application install molding from
center of unit to ends.
Alternative method, staple membrane in place using ½” staples 3”-5” apart then
apply bar.
If roof-edge moldings are not installed on roof during this time membrane
will peel-up as drying.
8. Apply putty/butyl tape to the backside of the front and
rear termination moldings/caps. Front cap will lay on top of the membrane,
membrane should lay on top of the rear cap. Reinstall termination molding using
screw type fastener, make sure to screw into sufficient roof structure to
prevent lifting. Both edges of the front and rear roof molding must be sealed
with caulk/sealant. A minimum 3/8” bead will work for most applications.
Openings & Vents and Appliance Installation
1. Using a utility knife “x” cut all roof openings. Make sure
you round all 90-degree corners to eliminate the possibility of running cuts.
2. Surplus material must be secured by staples or screws
inside the openings, trim all excess material.
3. Apply putty/butyl tape to all vents and accessories, when
installing if any bubbles are noticed in membrane smooth bubble to vent opening
and secure vent with screws.
4. Seal around all vents and accessories. Apply sealant to
all visible screw heads. There is no need to spread the sealant as you are
applying it. A minimum 3/8” bead will work for most applications.
*Butyl tape provides the “Primary Seal” against water infiltration or penetration in these membrane roof assemblies. The lap sealant is a secondary seal. Butyl tape must be compressed 30% to 40% to perform correctly.

Class A Customs Warranty Registration Must Be Completed Within 30 Days for warranty to be valid.
Class A Customs Acrylic Water Based Adhesive
Water base adhesive designed for use as a bonding adhesive for single ply
roofing membranes.
Designed to Bond EPDM, PVC, and Hypalon to wood fiberboard, plywood, EPS, any
typical polyisocyanurate insulation, gypsum, concrete, etc.
May be applied by spray, roll coating, or by brush.
Grows stronger and adheres more with age.
Remains flexible to compensate for expansion and contraction of the membrane
itself.
COLOR White
COVERAGE 160-200 sq ft/gal (1side @ 8-10 mil)
May be applied by spray, roll coating, or by brush.
(When using spray application an Aro 650095 4.25 inch air motor with a 30:1
ratio pump @ 80 psi using a 651-500 gun equipped with #651551 quick clean and
spray tip #T.C. 1565 with 0.015 orifice or similar equipment is recommended).
For maximum bond strength a two-sided application is recommended.
If one surface is porous, such as plywood or fiberboard, it is acceptable to
wet laminate the membrane to the substrate.
If both surfaces are non-porous, such as EPS or ISO apply the adhesive to both
surfaces 4 - 5 mils and allow to dry approximately 20 - 30 minutes, depending
on conditions.
Adhesive will turn from white to clear when it is dry.
Apply membrane to roof deck and roll or broom down sheet to assure 100% contact
area.

Putty Tape
Non-hardening, pliable putty tape.
Color Gray
Waterproofs overlapping metal seams.
1/8" high X 3/4" wide - Roll 30 feet long
Class A Customs Self-Leveling Silicone Caulk (Color White 10.1 fl oz
Tube)
All weather self-leveling sealant designed and formulated to provide excellent
weather resistance.
It features high solids, low V.O.C. content, and no hazardous air pollutants
(HAP).
This compound provides good adhesion to a variety of substrates.
This product has good low temperature resistance and will not crack at -40oF.
Typically used in RV applications where a long-term weather tight seal with
good ozone and UV resistance are required.
Cured sealant is paintable.
Surfaces should be free of dirt, oil, or other contaminants. A solvent cleaned
surface is optimum.
PRECAUTION ON ALL PRODUCTS
This material in the liquid or vapor phases is extremely flammable. Keep away
from sparks and open flame - do not smoke by this product.
Avoid prolonged breathing of vapors of this product - use in a well ventilated
area. Prolonged breathing of vapors may cause headaches and even
unconsciousness.
Direct contact of uncured sealant irritates eyes and may irritate skin. In case
of eye contact flush eyes with water for 15 minutes and call a physician. In
case of skin contact, thoroughly wash skin with soap and water.
Material may be harmful or fatal if swallowed. If swallowed, do not induce
vomiting. Seek medical attention immediately.
Answer: Either side can be installed facing down. Some people think for better traction to install with the textured size facing up and the smooth side down toward the roof (facing glue), some people think for easier cleaning to install the smooth side facing up.
Question: My roof turned pink!
Answer: This will happen when your roof is exposed to too much carbon dioxide, you leave the unit indoors or covered too long with no access to fresh air, once the unit is outside the pink will slowly disappear.
Answer: The solvents in the self-leveling sealant temporarily swell the roofing membrane. In the warmer months it takes 3-5 days to go away & 5-9 in the colder months.
Question: Cleaning The Roof
Answer: Be sure to only clean each material with appropriate cleaning materials, we do not sell cleaning products.
