Totally dry during normal temperature water test.
Customer: SEASPIRE INTERNATIONAL (No.20 Enterprise Centre)
Date Completed: Feb 2014
Problem: Epoxy paint gave way to low temperature hairline cracks which result in water
seepage onto epoxy flooring causing flaking of paint through various points within 2 tank at
pipe joints area. Most “Green” label water proofer does not withstand low temperature
operation and the contraction of membrane will cause water ingress/seepage towards
hairline cracks. The penetration of Seal Once MSC could reach upto 1’’ inch but subject to
surface porousity.
Solution: Grind completely and remove existing internal epoxy paint and apply 2-3 coats of Seal
Once MSC nanotech water proofer till surface cannot absorb further. Grind external leakage points
1m by 1m with the leakage point in the middle for water plug treatment with Seal Once Negative
Pressure Water (NPW) before applying 2 coats Seal Once MSC nanotech water proofer and the
problem were solved.
Active but green ingredient present inside Seal Once MSC will prevent the growth of fungi / algae
and only a sponge is needed to do maintenance cleaning inside the tank.
Duration of whole work: 2 & half days. (Exclude water test for 72 hours with
pumps activated and temperature to be around 12 Degrees Celsius)
