Dampcourse and roofing.
An organic fibre felt which is completely saturated in hot bitumen then coated with further selected bitumens and finished with a dusting of fine powder to prevent sticking when rolled.
Uses
- Waterproofing flat roofs, roof tiles, corrugated fibre cement and corrugated iron sheet roofing.
- Dampcourse for brickwork etc.
- Separation strip, for timber brickwork and concrete.
- Underneath galvanised water tanks to prevent condensation.
Features & Benefits
- Highly economical waterproofing membrane.
- Mild acid, alkali and moisture resistant.
- Easy to lay.
Surface Preparation
- Surface must be structurally sound and free from grease, oil, wax and other loose or contaminating material which may affect adhesion.
- Area to be waterproofed should have adequate drainage to prevent water ponding.
Application
If you have conventional planked or sheet timber roof, nail the first underlayer of felt to the decking, parallel with the drainage fall, using 20mm extra large head galvanised clout nails. Start nailing at 150mm centres. Overlap the second and subsequent sheets by about 50mm, seal the overlap with Bitumen Paint and nail along the overlap at 50mm centres.
The second underlay must be bonded to the first with Bitumen Paint. You will find it easier to handle half a length of felt at a time: lay the sheet flat on the roof, roll half of it back and then paint the Bitumen Paint on to the roof. Unroll the sheet on to the Bitumen Paint, press it into place, making sure that there aren’t any air pockets trapped underneath. Roll back the other half, apply the Bitumen Paint, then smooth this half into place. You can fix the top layer of felt (the cap sheet) in the same way. Cover the edges of the roof with felt strips called “welted aprons”.
Finish off the roof by applying a coat of Silver Aluminium based paint to the entire roof for U.V. protection.
Precautions
- Store rolls upright.
Clean Up
Tools and other equipment can be cleaned with turpentine.
Packaging
- 20 metre rolls × 90mm, 110mm, 150mm, 230mm, 270mm, 300mm, 350mm, 450mm and 1 metre
