Method of Application
1 . R E PA I R I N G DA M AG ED CO N CR E T E R O O F S CR EED :
} Use a mechanical cutter to remove loose, damaged, or hollow-sounding sections of the concrete screed in
localized areas (pockets).
} Thoroughly clean the exposed concrete screed with clean water to remove any dirt, dust, or loose particles.
} Prepare a 1:1 (by volume) mix of Dr. Fixit Pidicrete URP polymer and cement. Apply bond coat using a brush to
the entire exposed concrete surface. Prepare a polymer-modified mortar (PMM) by mixing Dr. Fixit Pidicrete
URP (10% by weight of cement) with M20 concrete mix in a 1:1.5:3 ratio (one bag of 50kg cement: 1.5 parts
sand: 3 parts coarse aggregate).
} Level the repair and damaged areas of the concrete screed in a smooth trowel finish, creating a proper slope
for drainage.
} Keep the repaired surface moist for 7 days, this can be achieved by spraying water regularly or covering the
area with wet burlap.
} Allow the entire screed to air cure for an additional 4-5 days before applying roof top coat coating system.

2 . CR ACK R E PA I R :
} All hairline cracks which are more than 0.50 mm in width and not giving hollow sound, should be cut, and
widened in V shape with mechanical cutter in the size (8mm W x 6mm D) and fill with Feviseal HY100 Hybrid /
PU sealant with suitable gun.
} Allow sealant to cure a minimum 72 hours (about 3 days).

} Apply thick coat of Dr. Fixit Wonderproof 100 and cut of 2.5 mm x 2.5 mm 45 GSM glass fiber mesh /40 - 60
Gsm Geo Textile fabric in 50mm width to cover crack area. Apply another coat of Dr. Fixit Wonderproof 100
after 3-4 hrs. coating towards the length of the crack to ensure complete hiding of mesh/fabric. Ensure there
are no pinholes or air bubbles on the membrane.

} Carefully chip and hack away the surface around the rainwater drain outlet mouth to a depth of approximately
25 mm. This creates a roughened surface for better adhesion.
} Prepare a 1:1 (by volume) mix of SBR-based polymer and cement bond coat slurry and apply over the corners
and gaps around the water pipe outlets.
} Prepare a polymer-modified mortar (PMM) mixed with 10% SBR-based polymer (by weight of cement) in a 1:3
ratio and fill the gaps around the drain mouth with PMM, finishing etc complete. Allow the repaired surface to
cure as per standard practice.
} Embed a 100 mm wide strip of either 45 gsm fiberglass mesh or 40-60 gsm geotextile fabric around the
entire perimeter of the drain mouth.
} Apply two thick coats of Dr. Fixit Wonderproof 100 waterproofing coating to completely cover the mesh/fabric
and surrounding area.
} Allow the first coat to air cure for 3-4 hours, apply a second coat of Dr. Fixit Wonderproof 100 over the entire
treated area around the rainwater outlet.
4 . V ER T I C A L U P S TA N D D E TA I L I N G FO R M S A N G L E S :
} Use Dr. Fixit Rust Remover to remove rust from steel reinforcement, MS pipelines, MS plates, and MS angles.
} Remove loose rust using wire brushing, chipping, hammering, or grinding to remove most of the rust scale.
} Apply Dr. Fixit Rust Remover to the affected surface using a cotton waste swab or brush.
} Allow the surface to react with Dr. Fixit Rust Remover for at least 15-30 minutes.
} Wash the steel surface with a water jet to remove acidic residue and clean with a cotton cloth.
} Apply a coat of Dr. Fixit Zinc Rich Primer and allow to air cure for 12 hrs.
} Apply two thick coats of Dr. Fixit Wonderproof 100 over the entire upstand, embedding it with 45 GSM 2.5mm
x 2.5mm fiberglass mesh or 40-60 GSM fleece while the Dr. Fixit Wonderproof 100 is still wet.
} Ensure good coverage and complete saturation of the mesh/fabric.
} Once the final coat is dry, inspect the membrane for any pinholes or air bubbles.
5 . M IX I N G :
} Premix Dr. Fixit Wonderproof 100 components A and B with an electric double paddle mixer stirrer for 2-3
minutes at a slow speed. Thorough mixing of components in two-part products is crucial.
Note: Ensure complete mixing throughout the material, especially along the sides and bottom of the pail, until
a uniform consistency is achieved.
6 . WAT ER P R O O F I N G A P P L I C AT I O N :
} Ensure the concrete screed, China mosaic, Clay tile, BBC screed surface is in Saturated Surface Dry (SSD)
condition before of topcoat application.
} Apply the first coat of Dr. Fixit Wonderproof 100 at a rate of 0.45-0.50 Kg/sq.mt/coat. Place a 45-GSM glass
fiber mesh with a size of 2.5 mm by 2.5 mm between the first and second coats while the first coat is still wet.
Allow the first coat to dry for 4-6 hours.
} Apply the second and third coats of Wonderproof 100 with the same application coverage, but in a direction
perpendicular to that of the first and second coats. Allow each coat to air cure for a minimum of 3-4 hours
after application. Ensure that no void surface is left untreated or uncoated. All coats should be applied in
directions perpendicular to each other, ensuring the correct consumption of material, resulting in a total dry
film thickness of 900–1000 microns with system coverage in three undiluted coats at a rate of 1.35 -1.50 Kg/
sq.mt/coat.
} Note- It is mandatory to reinforce Dr. Fixit Wonderproof 100 coating with 45 GSM glass fibre mesh as a
reinforcing material.
} Allow the coated surface to air cure fully for 5-7 days.
