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 for long periods, 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 snap and 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.
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.
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.
The solvents in the 1021 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.
Be sure to only clean each material with appropriate cleaning materials, we do not sell cleaning products.
Class A Customs no longer carries Alpha SUPERFLEX at this time.
Class A Customs Acrylic Water Based Adhesive is a technically advanced
scientific formula of water base adhesive designed for use as a bonding
adhesive for single ply roofing membranes.
Class A Customs
Adhesive is a high solids adhesive with a short drying time. It is used
in the Recreational Vehicle and Commercial Roofing industries to adhere
membranes to wood decking (not designed for fiberglass).
It is ideal for applications where a quick dry time is dictated by production line speed or other variables.
Class
A Customs Adhesive does not lose peel value over time, but remains
flexible to allow for expansion and contraction of the membrane. When
tested side-by-side with competitors RV adhesives, Class A Customs
Adhesive was proven to be stronger and keep a better hold on both the
rubber roofing, and the materials it was applied to.
Water Based Acrylic AdhesiveFast Setting - dries clear
Bond
grows stronger with age but remains flexible to allow for expansion and
contraction of various roofing materials. Excellent adhesion to
plywood, particleboard, MDF, and most roofing membranes such as EPDM,
PVC, TPO, etc...
Coverage 160-200 sq ft/gal
Best when applied in air temperatures over 50 deg F (10 deg C)
For glue roller applicators and glue spreaders, can be hand applied by brush.
Apply to one substrate with 10-12 mil coat weight to achieve excellent bond.
To
achieve best bond, apply to both substrates with 5-6 mil coat weight
and allow to dry, then laminate to membrane and apply pressure with
roller to insure 100% contact.
Diluent Water, if required. Use as received.
Clean-up requires only warm water.
Store product in a cool, dry area.
Product should not be stored in direct sunlight.
