A. SUBSTRATE PREPARATION
Cementitious or mineral based substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and to achieve an open textured surface. Loose friable material and weak concrete must be completely removed and surface defect. The concrete must be carefully assessed for moisture content, air entrapment, and surface finish prior to any primer application. Apply the TT Primer, at the correct consumption to the prepared dry surface and allow to dry before next application stage.
B TORCHING
Use a gas burner to heat the substrate and the backing film on the underside of membrane.When the backing film starts to melt, the membrane is ready to stick. Roll the membrane forward and press firmly against the substrate to bond. Ensure a bead of melted bitumen is visible along the full length of the overlap sides and ends when laying. Embossed membrane versions require less torching.
C. DETAILING
All details such as internal and external corners, upstands, vent pipes, drains, support metalwork etc. must be cut and sealed effectively. Detailing must follow the recommended guidelines and good practice for torch-applied membranes
D. PROTECTION
The membrane applied over the terrace, must be finished with a coating of Torchtar aluminium paint for non-foot traffic area. For foot trafficked area, overlay with concrete screed mortar.
PRECAUTIONS:
- Do not apply during rains or extreme temperatures.
- Avoid abuses which may lead to puncturing of membrane.
- Ensure that the product is applied at least 6 inches inside the drain pipe.
- Apply parapet to parapet to envelope the entire building for long term performance.
