The working area will be clear and free of all contaminants. Moisture must be
eliminated from the working area for successful GRP application. All
hydrocarbon substances such as oils and lubricants will be removed for perfect
ad-hesion. Any other surface impurities will also be removed.
Cleaning may include brooms brushes vacuum cleaners for the removal of
heavy and fine particles.
Materials will be stored in a manner to avoid spills causing staining.
Edges will chamfer, and corners rounded with the prescribed filler before the
lining is applied. Imperfections will be rectified with the use of resins suitable
for the GRP application.
A bonding coat such as will be applied thinly to the working area to assist the
chopped strands mat adherence to the working surface.
After the bonding coat is cured, the chopped mat strands will be applied to
make sure that the CSM is sufficiently wet for good application. Ensure enough
impregnation of the CSM to avoid the exothermic heat.
A second layer of the CSM can be applied again using the steel roller when the
first layer is sufficiently cured.
Approximately Four layers will be required to achieve the depth of 4mm GRP.
It is recommended to use 50mm overlapping for the laminating process.
When complete and sufficiently cured the surface will be inspected for
anomalies such as air pockets and exposed matting. Remedial work should be
conducted using sanders if required.
When complete and signed off as complete and in compliance by the QA/QC a
final gel coat will be applied using glass fibre tissue.
The gel coat should have the properties of anti-corrosion properties and
provide a smooth surface in compliance with the job order.
The covering slap will require just two coatings of the gel coat to provide
When the installation is complete and working materials such as tool and
access platforms will be removed from the working area.
The floor application of the GRP will now follow the same protocol as the walls.
Drainage systems and catchment areas will be also GRP lined to a depth of
4mm in compliance with the original drawings.
