AQUAFIN-2C is one of Pakistan’s most trusted cementitious waterproofing systems for basements, rooftops, water tanks, balconies, sewage structures, retaining walls, and reinforced concrete. Its high flexibility, crack-bridging properties, strong adhesion, and resistance to over 5 bars of hydrostatic pressure make it ideal for long term structural protection. 


But even the strongest waterproofing system needs the right post-application maintenance to reach its full performance life. Below is a complete guide on how to protect, maintain, and extend the life of your AQUAFIN-2C coating. 



roof waterproofing in Pakistan





 1. Allow Correct Curing and Hardening (Critical Stage) 

• The first 24–72 hours after application directly determine performance. Incorrect curing is the #1 cause of waterproofing failure in Pakistan.

 • Rain Exposure Limits

 • Vertical surfaces: Safe after 3 hours. 

 • Horizontal surfaces: Safe after 6 hours.

 • Hydrostatic Pressure Resistance

 • AQUAFIN-2C is ready to withstand pressure only after reaching Shore A Hardness 85—typically 3–7 days depending on weather.

 • What is Shore A Hardness?

It’s a measure of how firm and cured the coating is. At 85 Shore A, the membrane becomes tough, elastic, and fully capable of resisting water pressure.

 • Backfilling Timeline

 • Backfilling around foundations should be done after 3 days (at 20°C, 60% humidity).

 • Early backfilling can puncture or damage the membrane. 




 2. Control Site Conditions During Early Strength Gain 

  Aquafin-2C allows foot traffic after 1 hour, but:

 • Avoid heavy loads, machinery, and dragging objects until full curing.

 • Tile Installation

 • Install tiles after 24 hours.

 • Use flexible polymer-modified tile adhesive. 

 • Avoid Thermal Shock

 • Hot weather in Pakistan (above 30°C) can cause:

 • Rapid drying

 • Cracks

 • Loss of elasticity

 • Always protect fresh coating from direct sun and hot winds for the first 24 hours.


 3. Use Proper Drainage & Protection Systems 

 • For long-term performance, especially in basements:

 • Use drainage boards, geotextiles, or protection boards.

 • Backfill only with clean, rounded gravel.

 • Ensure drains and weep holes are open and functional.

 • Poor drainage increases hydrostatic pressure, stressing the membrane unnecessarily. 


 4. Keep the Surface Breathable

 AQUAFIN-2C is vapor-permeable — meaning moisture can escape without blistering the coating.

 To maintain breathability: 

Allowed: 

• Breathable water-based coatings 

• Cementitious plasters (after 24 hrs) 


Not Allowed:

 • Solvent-based paints

 • Bitumen membranes directly on top

 • Epoxy coatings 

• Trapping moisture can cause peeling or failure over time.

 

 5. Inspect Cracks & Movement Areas 

• AQUAFIN-2C bridges static cracks up to 2.5 mm, thanks to its high flexibility and elongation.

 • But dynamic cracks (movement or expansion zones) require reinforced waterproofing.

• Use: 

• ASO-Joint-Tape 2000 

• ASO-Joint-Tape 2000 S

 • These ensure watertight continuity in joints, corners, and structural movement areas. 


 6. Routine Maintenance Every 6–12 Months

 • Especially important in Pakistan’s monsoon climate.

 • Checklist:

 • Inspect for abrasion, impacts, and surface damage

 • Remove efflorescence and salt deposits

 • Check roof drains for blockages

 • Prevent standing water (especially on rooftops)

 • Routine check-ups significantly extend the system’s lifespan. 


 7. Avoid Contact With Alkali-Sensitive Metals 

• Do not apply AQUAFIN-2C directly on: 

• Copper 

• Aluminum 

• Zinc-coated steel 

• Prime these surfaces with a proper anti-corrosive primer first. 


 FAQs — AQUAFIN-2C 


 1. How long does AQUAFIN-2C last? 

When installed and maintained correctly, AQUAFIN-2C can last 10–20 years.



 2. Can AQUAFIN-2C stop active leakage? 

 No. Stop active leakage using AQUAFIN WaterStop or pressure plugs before applying.



 3. Is it suitable for rooftops in Pakistan? 

Yes. It resists: 

• UV 

• Rain 

• Heat 

• Thermal expansion 

• Perfect for roof leakage solutions. 



4. When can I fill a waterproofed water tank? 

 After 3–7 days, once full curing is achieved.



 5. Can I paint over it?

  Yes—but only with breathable, water-based paints.



 6. Can it be applied on damp surfaces?

  Yes. AQUAFIN-2C requires SSD (Saturated Surface Dry) substrate.


Conclusion 

• AQUAFIN-2C is one of Pakistan’s most reliable systems for basement waterproofing, roof leakage protection, tanks, pools, and concrete protection under hydrostatic pressure. 


• By following the right curing process and adopting regular maintenance, you ensure the coating performs at its full potential for years or even decades. • Its flexibility, crack-bridging capacity, and strong adhesion make it a long-lasting solution for both residential and industrial waterproofing needs.
