Sweep your terrace from all the dust. After sweeping use a wire brush to thoroughly remove any weak deposits on the terrace.

Once done with the above two jobs, use the water hose to remove traces of dust.

Step 2: Repair Cracks:

Once you have cleaned your terrace, you will see a few cracks here and there. Open those cracks a tiny bit using a grinder. We are opening the cracks so that they can be sealed properly. Remove the dust using a blower.

Now make a mortar using a repair latex (E.g. Dr. Fixit URP) 1 kg cement, 150 gm repair latex, and water as per workability. Sprinkle water over the cracks and let it dry for 10-15 mins. Apply the mortar over the cracks and flatten them. Wait for 24 hours to let it dry.

Step 3: Check the status of the Angle Fillets:

Angle Fillets are the transitional edge between the parapet wall and roof surface. It is made at an angle of 45 Degree, having dimensions of 100 mm X 100 mm. Check the image below for clarity.

If there is no fillet on your terrace, construct one using mortar around all the parapet walls covering the perimeter of your roof. If there is an existing fillet, check for any damage and repair it with the repair mortar.

Step 4: Sealing of drainage pipes:

Areas near the sealing drain or outlet pipes are vulnerable to water leakages. Seal the periphery of the same using the repair mortar as an added precaution.

Step 5: Waterproofing coating application:

There are many options in the market for waterproof coating like Dr. Fixit Roofseal, Asian Paints Dampproof, etc. We recommend Dr. Fixit Roofseal because of its superior material quality. The coatings can not be applied during rain.

Spray water on the terrace and let it dry for 20-25 mins. Now apply primer coat ( make primer from your coating chemical by it with 50% water. In 20 Liter bucket, add 10 Liter water) on the surface. Let it dry for 3-4 hours.

Apply the first coat (no dilution) on the primed surface in one direction. No zig-zag painting. Apply unidirectionally over your roof. After the first coat, wait for 4-6 hours. Apply the second coat perpendicular to the direction of the first coat. Finish the job. Initial drying will take 4-6 hours. Complete drying takes 3 days, after which you can walk on the terrace.
