General advice when laying a Cure It roof
Repairing a Cure it roof
If the roof surface becomes damaged by impact or has to be cut for any reason it can be easily repaired using the following procedure:
1. Wipe off the damaged area with acetone and lightly abrade the GRP surface with a hand grinder for a distance of 100mm from the damaged
area or edge to be joined.
2.Cutthe450/600gm²glassto200mmextrathanrequiredtocovertheaffectedareaandriptheedgesforafeatherednish.
3.Mixsufcientresinwithhardeneraspreviouslydescribed.Brushresinontotheareatobelaminatedattherateof0.5kg/m

.
4. Place the glass over the area, wet out the glass with resin at the rate of 0.5kg/m
2
. Stipple well with the brush or use
a paddle metal roller for larger areas.
5. Ensure that the laminate is free from air and completely consolidated and allow to cure.
6. Mix the Topcoat with hardener as previously described and apply with a brush at the rate of 0.4kg/m

.
7. Allow to cure.
This procedure will ensure that the patch or joining piece applied will bond to the original laminate and form a weatherproof patch over the
damaged or cut laminate.
Advice when using Cure It during Winter months
• Always check the local weather forecast.
• During the Winter, avoid topcoating a roof after 2-3pm unless it is a clear bright day and not too cold. The heat from the sun contributes a
great deal towards the curing of the laminate during colder months. After the sun has set, it is unlikely that the topcoat will cure over night.
 Ifleftuncured,thetopcoatmaycurewithdebrisandleavesstucktothesurface,orwithanundesirablenishifitrains.
• EnsurethatthesurfacetemperatureoftheboardsischeckedbeforelayingtheCureItRoongResinorTopcoat.(canuseinfraredthermometer)
• EnsurethattheCureItRoongResiniskeptwarmbeforeuseiftheambienttemperatureisbelow10

• AlwaysensurethattheCureItRoongResinremainsindoorsinawarmplacethenightbeforeitisused.
• DonotuseCureItRoongResinorTopcoatintemperaturesbelow5

• Ifitbeginstorain,covertheroofwithavisqueensheet.
• Ifyouareunabletolaminateoveraprepareddeck,thencoatthedeckingwithhardenermixedwithCureItRoongResinandcoverany
exposed edges. This will seal the deck and prevent moisture uptake until the laminate can be applied. Always cover the edges of the roof
and uncoated boards with a polyethylene sheet.
• Always ensure the deck or substrate to be laid onto is completely dry before laying the laminate. Sweep off any excess water and mop up
the excess with dry cloths before allowing the roof to dry naturally. Wiping the surface with acetone can speed up this process.
• Do not start to lay a roof if a period of rain is forecast.
Advice when using Cure It during Summer months
• Always check the local weather forecast.
• DonotuseCureItRoongResinorTopcoatintemperaturesabove35
o
C.
• AlwaysmixsmallerbatchesofCureItRoongResinthanyounormallywouldtogiveadequatetimetoapplyitbeforeitstartstocatalyse.
• AlwaysuseextraslowhardenerinhotterweatheriftheCureItRoongResinstartstocuretooquickly.
• Always apply the laminate in the shortest runs possible across a roof. The shorter the length of laminate, the less likely it is that the Cure It
 RoongResinwillcatalysebeforeitcanbeconsolidatedintothelaminate.
• Use a temperature sensor to measure the surface temperature of the laminate before applying the topcoat. On surfaces that are too hot,
the wax component of the topcoat will melt and the topcoat may remain tacky to the touch, this will usually mean that any loose debris will
stick to the roof and the colour of the topcoat will also be impaired.
• If possible, topcoat the roof out of direct sunlight or wait until later in the day before applying it, this may mean that the roof will take you
longer but it will save you time spent returning to the roof to re-topcoat it at a later date.
Safe working practices
It is always the installer’s responsibility to ensure safe working practices for themselves and their employees and always pay attention to the
risks for other members of the public that may be nearby at the time. Installers should always assess any potential risks when working on a
contractandmakesufcientmeanstoaddressthem.Inadditiontothesenotes,theinstallershouldalsobeawareofthehealthandsafety
information that applies to most materials (see the relevant material safety data sheet for further information).
