Bitumen tape rubber (also known as bituminous sealing tape or rubberized bitumen tape) is a flexible, self-adhesive waterproofing tape made by combining bitumen (a petroleum-based adhesive) with rubber or polymer components. It is usually reinforced with a layer of aluminum foil, HDPE film, or non-woven fabric on one side and has a peel-off release liner on the adhesive side.

🔧 Key Properties:

Waterproof and weather-resistant

UV-resistant (depending on surface layer)

Flexible and self-sealing

Strong adhesion to various surfaces (metal, concrete, plastic, wood, etc.)

Withstands temperature changes and vibrations

✅ Common Uses:
Sealing roof joints, flashings, skylights, and chimneys

Waterproofing gutters, valleys, and eaves

Patching cracks or holes in metal or concrete

Wrapping and protecting underground pipelines (anti-corrosion)

Sealing around windows or doors during construction

Damp-proofing foundation walls

🛠️ Effective Ways to Use Bitumen Tape Rubber:
Surface Preparation:

Clean the surface thoroughly: Remove dust, oil, rust, loose particles, or any old sealants.

Surface must be dry and stable for best adhesion.

For porous or rough surfaces, applying a bitumen primer can improve bonding.

Measure & Cut:

Cut the tape to the required length using scissors or a utility knife.

Allow for overlap of at least 50mm (2 inches) if using multiple strips.

Peel & Stick:

Gradually peel back the release liner while applying the tape to avoid wrinkles or air bubbles.

Press the tape firmly into place using a roller or hand pressure.

Seal the Edges:

Run your finger or a tool along the edges to make sure they’re tightly sealed.

Overlap joints or seams to ensure continuous waterproofing.

Temperature Tip:

Best applied in warm weather (above 10°C / 50°F).

In cold conditions, warm the tape slightly with a heat gun or keep it indoors before use to improve flexibility and tack.

⚠️ Pro Tips:
Do not apply on wet or frozen surfaces.

Not ideal for high foot traffic areas unless overlaid with additional protection.

Store rolls in a cool, dry place, away from direct sunlight.
