Methodology
Surface Preparation
All surface imperfections, protrusions,
structurally unsound and loose concrete
must be removed and repaired with polymer
modified mortar using Dr. Fixit Pidicrete URP.
All surfaces must be cleaned with compressed
air, free of loose materials, oils, form release
agents and other contaminants.
Light fitting casings, pipes, insert, etc., provided
in the concrete raft floor and walls are to
be grouted with a non-shrink grout, Dr. Fixit
Bathseal Grout. The inserts shall be wrapped
around with Dr. Fixit Bathseal Tape to ensure
a water-tight fitting.
Priming
Priming generally not required on concrete
substrates for Dr. Fixit Extensa.
Application
Spray apply Dr. Fixit Extensa to achieve
minimum thickness of 2.0 mm
Dr. Fixit Extensa is applied through designated
equipment only. It cannot be sprayed through
any other type of commonly available sprayers.
Extend the Dr. Fixit Extensa coating up to
the top and covering the overflow concrete
channels all around the periphery of the pool.
As per the plans drawn up by the structural
engineer, lay the steel cage accordingly.
System Life
Expectancy
of 10 years
Reinforcing steel must be installed after the
plumbing is complete. The steel is installed
in a grid pattern following the requirements
of the engineering calculations. Steel bar size
can range from 3/8” diameter to 3/4” diameter
depending on the requirements.
Concrete spacers ensure the steel is not
against the wall or the floor of the pool.
This system allows shotcrete to be evenly
distributed under and above the steel.
a rule of thumb to remember when designing
swimming pools is to minimize the number of
separation joints between concrete sections
in the pool!
Finish the shotcrete area with wooden float.
After curing and drying make angle fillets if
necessary, all around the periphery of the pool
wall with polymer modified mortar prepared
with Dr. Fixit Pidicrete URP.
Now the shell of the swimming pool is ready to
receive further waterproofing system.
Apply 1st coat of Dr. Fixit Fastflex maintaining
the saturated surface dry condition.
While the coat is still wet embed a glass fibre
mesh of 2.5 mm x 2.5 mm of 50 gsm over the
angle fillets and allow it to soak completely.
Immediately apply one additional coat to
sandwich this glass fibre mesh between the
Dr. Fixit Fastflex coatings.

Apply the 2 nd coat of Dr. Fixit Fastflex.

(LSP)
After the 2nd coat is completely dry apply 3rd coat of Dr. Fixit Fastflex and sprinkle coarse
sand while it is still wet. This will provide the
key for subsequent tile adhesive materials.
Dr. Fixit Fastflex should be liberally applied
around the inserts, pipes and the around the
light fitting casings, sandwiched with an open
woven mesh as an extra precaution about
these points.
Now, start the application of tile adhesives
from ROFF range depending upon whether
they glass mosaics, or ceramics and fill the
grooves / tile joints with epoxy based RTM
coloured tile grouts.
