Some brief guidelines for Huiyuan bitumen tape...

Ensure all surfaces are clean, dry and dust-free. Remove any loose particles and any rust with a wire brush & soft broom.

The use of gloves is recommended.

Rough, porous or friable surfaces (such as wood, cement boards, course brickwork, breeze blocks etc..) should be primed with a bituminous primer and allowed to dry in order to improve bonding strength. (we sell primer in 1ltr 2.5ltr and 5litre tins)

1. Roll out the flashing strip then cut to the required measured length
2. Remove the backing paper (peel back 150mm) and place the adhesive side to the previously prepared surface
3. To ensure a tight contact - smooth the tape down with a dry cloth, removing all the air bubbles
4. Press the tape to the surface firmly once in position
5. Repeat the steps 2-4 in 300mm to 600mm sections until the area is covered
6. If the tape is joined ensure all overlaps are greater than 25mm
7. Smooth flat all edges with a wallpaper roller or trowel
8. After use reseal pack and store upright in cool, dry condition
