Stage 3
Laminating
Deck is coated with Cure It Roofing Resin
Figure 4.
Premium cost options:
When a client specifies a Cure
It roof there are a number of
different options available for the
weight, colour and finish of the
roof. All of these should be charged
at a premium.
- The Cure It laminate can be
specified in two weights: 450g/
m² and 600g/m². 450g/m² is
the standard weight for most
installations and will withstand
foot traffic. 600g/m
2
should be
specified where the roof will be
subject to regular heavy foot
traffic such as a walkway or
balcony. This would normally be
specified with an aggregate slip
resistant finish.
- The roof can be finished in any
BS4800 colour.
- The roof can be finished with a
standard smooth or two choices
of non-slip finish (see next page.)
Consolidating
Let the Cure It Roofing Resin soak into the mat to break down the binder for 2 to 3 minutes. Using the
paddle roller and applying a little pressure, roll back and forth along the 2 edges and the end of the wet
mat. Now roll the paddle roller over the whole of the wet out mat, ensuring the paddle roller makes at least
2 passes over the whole area. In colder weather the resin will be thicker and will take a little longer to wet
out. When a laminate is correctly wet out it should be transparent, there should be no white or opaque
areas. Take care near the edge of the roof and in windy conditions as a fine spray will be emitted from
the roller.
Make regular close inspections of the laminate as it is consolidated, checking for ‘pinholes’ and areas short
of Cure It roofing Resin. Pinholes in the laminate will lead to porosity and water penetration.
While completing the next metre wide run of laminate, put a quick ‘wash coat’ of the resin
(1 roller full per 2m
2
) over the previous run of finished laminate.
On all overlaps of the mat, pay extra attention to the ‘feathering in’ as this will improve the overall
appearance of the finished roof.
Preparation for topcoating
Taking care and paying attention at this stage will produce a roof of superb appearance. Using a Cure It
sanding pad with a 40 grit sand paper, lightly sand the corners and trim bandages. Sand off any unsightly
fibres, taking care not to sand too heavily on the corner itself as this may lead to holes appearing. Cut any
excess cured mat protruding beyond the trim with a sharp Stanley knife.
Seal any abutments with walls using a clear silicone sealant. Fit any C100 simulated lead flashing before top
coating and seal off the chase with a clear silicone sealant or Cure It Trim Adhesive. Occasionally mortar will
be required to finish the chase.
Roller is dipped into Cure It Roofing
Resin and then applied to 1m length
of mat, one roller width at a time.
Consolidator roller is used after
allowing the Cure It Roofing resin to
break down the reinforcement mat
binder for a minute or two.
Finished laminate
should be transparent.
