Materials should be stored in an enclosed
 area in
whichtemperaturesareabove50°Fandbelow90°F.
They should not be stored directly on the ground.
Pallets should not be stored more than two high
withoutprotectivebracing.

LapCement:Asphalt‐basedroofingceme ntthatcomplies
withASTMspecificationD4586mustbeused.Application
withaserratedtrowelisrecommended.Further,cement
shouldbeusedonlyinanamountthatisnecessaryto
obtainadhesion.Innocaseshouldcementusageexceed2
gallonsper100squarefeetof
cementedarea.Ifadhesive
thickensincoolweather,placecansinwarmwater.DO
NOTHEATOVERFLAMES.

RoofDeck:Alldecksmustbefirm;solid;freeofsharp
edgesordepressions,moistureorfreezingeffects,and
dustordebris;andcapableofsupportingallanticipated
deckloads.Thesubstrateshouldconsistofdry,well‐
seasonedlumberofuniformthicknessnotmorethan6
incheswideoraproperlyinstalled
andconditionedroof
deckconstructedofexterior‐typeplywoodwitha 
minimumthicknessof3/8inch.Alternatively,APA‐rated,
non‐veneer‐structuredpanelsof7/16inchthicknessmay
beused.Piecesoftinorothersuitablemetalshouldbe
nailedoverallknotholesandlargecracks.Ifsheetmetal
is
notavailable,piecesofthisroofingmaybeused.Theroof
deckshouldbesweptcleanofalldirtandloosematerials.

Unrolling
:Rollsofcapsshouldneverbeputdownin
full‐lengthrolls.Theyshouldbecuttothefollowing
length: 2 16‐foot lengths.When ambient
temperature is below 60ºF and cloudy or overcast
Supercap membranes should be cut to 3 11‐foot
lengths (maximum) and placed in a warm area
(>50ºF) for 24 hours prior to application. Always
unrollthisroofingona flat,smoothsurface.Then,







loosely re‐roll the sheets the reverse way. The
roofing should be drawn up tightly during
application. Wrinkles should be pulled out during
finalfastening.

NewConstruction:Installmetalflashingaroundtheedges
oftheroof,usingahammerandroofingnailstosecureit.
Besuretooverhangtheroofatleast1/2inch.Cutthe
flashingtotheproperlengthusingapairoftinsnips.Cut
enough18‐inchwidestripsfromtherollroofingtocreate
starterstripsaroundalloftheedgesoftheroof.Spread
roofingcementaroundalloftheouteredgesoftheroof
usingalargepaintrolleraffixedtoarollerhandle.Sweep
thedecktoremoveanydebris,dust,orlooseparticles.
Applyalayerof15/30#feltoraG2baseovertheentire
roofdeckarea.Layinahorizontalmanner,lappingeach
course2inchesoverthelowercourseand4incheswhere
endsjoin.Laytheunderlaymentatleast6inchesoverall
hips,ridges,andvalleys.
Re‐RoofingApplication:Priortoapplyingthemembrane,
removeallgravel,loosenails,orslag.Donotapplyany
roofingmembraneoveramoistsurface.Ifthereare
blistersorbuckles,theyshouldbecutopen.Nailboth
edgestocreateasmoothsurface.Priortoapplyingthe
Supercap,theroofsurfaceshouldbesweptcleanofalldirt
andlooseparticles.Ifthesurfaceiswet,allowittodry
priortoapplyingthemembrane.

ApplicationofFastenersNails
:Properattachmentofall
membraneunderlaymentisessential.Uselarge‐head
corrosion‐resistantnails(11‐12gauge)withheadsofat
least1inchindiameter.Allfastenersshouldbelong
enoughtopenetrateintothewooddeckatleast3/4inch
orcompletelythroughaplywooddeckorOSB
aminimum
of1/8inch.

Valleys:Applyvalleysheetsfirst.Cutalengthofroofing
intotwostrips:one18incheswideforthelowerlayerand
one36incheswidefortheupperlayer.Foldthesestripsto
conformtotheangleofthevalleyorgutter.Toapplythe
lowerlayer,placeSupercapSBS
facedown.Startatthe
bottomandnailevery6inchesalongtheedges.Theends
shouldbebutted,notlapped.Coatthislayerwithlap
cementandapplytheuppersheetfaceupoverthelower
sheets.Theendsoftheuppersheetshouldbelapped6
inchesand
cemented,butnotnailed.Nailthesecond
sheetalongtheouteredgesevery6inches.Thesheets
usedtocoverthemainroofshouldoverlapthevalley
sheetstowithin1inchofthevalleyangle,alignwiththe 
rakelineofthevalley,andbecementedandnailedfor
long
sidelaps.
