INSTRUCTIONS FOR USE

The application temperature should be between 5°C to 45°C. Application procedures may vary slightly depending upon site conditions. The general recommended guidelines for the application of the waterproofing system are as follows:

SURFACE PREPARATION

The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections and protrusions shall be removed and repaired.

PRIMING

Apply Solvent based RANSBITU-PRIMER @ 0.3-0.4L /Sqmt as per ASTM D 41 & IS: 3384-1986 and BS 4147-1980 to a clean smooth and dry surface by brush, roller or spray. Allow the primer to dry prior to the application of the membrane. As the viscosity of the primer is low, it easily creates adhesion between the membrane and the pipe surface. In addition to that the primer also acts as a binder for the dust which gets accumulated on the pipe surface even after cleaning.

PRECAUTION:

Wash all the tools and tackles with industrial solvent immediately after the application is completed.

HEALTH & SAFETY

Avoid prolonged contact with eyes and skin. For detailed information refer to relevant material safety data sheet.

ALIGNMENT & TORCHING

After RANSBITU-PRIMER, next step is followed; RANSPIPE-CBT 2MM Pipe Wrap Coating is then wrapped around the pipe in spiral fashion and bonded to pipe by thermo fusion process using LPG Torch. An overlap of 10mm is to be allowed. The overlaps are to be sealed by thermo fusion process.

• A second coat of primer is applied over the first layer of RANSPIPE-CBT2MM and allowed to dry till it becomes tacky.
• RANSPIPE-CBT 2MM second layer is spirally wound over the first layer in spiral fashion and the overlaps are thermo fused.
• An area of 250 mm at the end of the Pipes is to be left uncoated to permit installation and welding. This area is to be coated after welding.
• CAUTION
• Do not over torch the membrane as this will expose the reinforcement and cause damage to it.
• SEALING
• Heat both the overlaps and use round tipped trowel to seal the overlap. Adequate heat is confirmed when a uniform flow of melted bitumen compound flows evenly in a bead that oozes from the applied membrane’s edges. Excess compound should be smoothened and pressed into the seam using a heated trowel. Any un-bonded areas must be lifted and re-torched. Do not attempt to reseal by torching the top surface of the membrane. Up stand.

Flashing details are accomplished using cut pieces of RANSPIPE-CBT 2MM in combination with appropriate prefabricated flashing components. The same side lap and end lap rules apply to flashing details as to field membrane.All angles and abutments should be sealed with extra care to ensure full bonding.All brushes and tools should be cleaned by water immediately after use.
