HYPERSEAL®-25LM-S
HYPERSEAL®-25LM-S is a single component, Polyurethane based, Low modulus expansion joint sealant and excellent thixotropic properties. It is moisture curing material to give 50% joint movement accommodation factor which has an excellent recovery capability and adhesion on substrates.
Sealing of joints:
- Precast concrete panels
- In-situ concrete
- Brick and block work
- Water tanks and swimming pools
- Metal frames
- Aluminium windows and panels
- Irrigation channels
- Glass, Granite & marble
SURFACE PREPARATION
The substrate must be cleaned or removed down to a solid and stable base material by using wire brush and air blower. The damaged concrete edge surfaces shall be rectified by using with HYGROSMART FIBRE or EPOXY RESIN 21-T.
LAYING OF BACKER ROD
Backer rod is laid over the prepared surface. This acts as the support for filling the HYPERSEAL PU sealant.
APPLICATION OF PRIMER
The sides of the joint should be primed with MICROSEALER primer (dry surface) and AQUASMART®- DUR primer (wet surface).
APPLICATION OF PU SEALANTS
After complete drying of primer, Masking tape is stretched and applied along the both sides of the line to be sealed. HYPERSEAL PU sealant is filled and it should be extruded into the joint so that ensuring no air is trapped in the joint. The edge masking tape should be removed before the joint sealant is hardened.
