Areas of Application:-

For concrete repairs – Spalled concrete of floors, columns, beams, chajja, slabs, parapets, etc.
For waterproofing – Small roof terraces, sunken portions of toilets & bathrooms, chajja & lift pits, balconies.
As a bond coat – For bonding of new concrete to old concrete, masonry stone work, plastering.
For cladding – Fixing or re-fixing of slip bricks, tiles, stones & marble bedding.
As external rendering – Weatherproof & frost resistant render.
As Bonding Slurry – As bonding slurry coat for pinhole treatment on concrete surface.

Method of Application:

1. SURFACE PREPARATION – 

Clean the surface with wire brush or scrubber to remove hidden dirt, loose particles, laitance & dust. Degrease the surface by using suitable solvents.

Repair the spalled concrete portion by saw, cutting the extreme edges of the repair location to a depth of at least 10 mm to avoid featheredging & to provide strong bond.

Clean the concrete surface to remove any contamination where breaking is not possible. Roughen the surface by light scrabbling or grit blasting.

For priming of concrete substrate, the surface should be thoroughly saturated with potable water. Remove any excess of water prior to application.

2. WATERPROOFING COATING –

For a waterproofing coating Mix URP: Cement in the ratio 1:1.5 by volume.

Mix for 2-3 minutes to avoid air entrapment. Keep on slowly adding cement to Dr. Fixit Pidicrete URP until the required consistency is achieved.

Brush apply 2 coats of the mix in a span of 4-6 hours on the prepared concrete substrate.

Overlay the coating with a protective screed to the desired slope & thickness.

3. BONDING PRIMER –

For a bonding primer coat of Dr. Fixit Pidicrete URP mix URP: Cement in the ratio 1:1 by volume.

Brush apply 1 continuous coat of the mix on the prepared concrete substrate.

Ensure to overlay the repair mortar when the bond coat is still tacky.

4. REPAIR MORTARS & RENDERS – A suitable mix ratio for patching repair mortar or render is as follows:

Mix design – Portland Cement: 50 kg, Washed sand: 150 kg, Dr. Fixit Pidicrete URP: 6-7.5 kg & Water: 10 Litre.

5. FLOOR SCREEDS & PCC – A suitable mix ratio for patching repair mortar or render is as follows:

Mix design – Portland Cement: 50 kg, Washed sand: 75kg, 6mm downsize aggregates: 75 kg, Dr. Fixit Pidicrete URP: 6-7.5 kg & Water: 10 Litre.

6. MIXING & APPLICATION –

A forced action mixer is essential (PAN Mixer) & recommended to ensure that Dr. Fixit Pidicrete URP mortar is thoroughly mixed. Use a suitable sized drum with heavy-duty electrical drill machine fitted with spiral paddle mixer at slow speed of 400-500 rpm.

Hand mixing is permissible only for 25 kg or less quantity.

Charge the mixer with required quantity of clean & dry sand(or coarse aggregates as needed), cement & mix for 1-2 minutes, then add the recommended dosage of Dr. Fixit Pidicrete URP dispensed in water which is pre-batched. Mix for 2-3 minutes to avoid air entrapment. Keep on slowly adding water until the required consistency is achieved.
