Bituminous Rubber Seal

FIELDS OF APPLICATION:

Bitumastic is ideally suited for sealing and filling gaps and joints on roofs, pointing horizontal chases for waterproofing membranes and felts. Sealing around roof/wet service pipes. Pointing between brickwork and roof flashings. Sealing cracks in asphalt and concrete pavements. Filling horizontal joints in concrete and asphalt where movements are not expected.

Environmental Information:

Contributes toward satisfying LEED® v4 requirements of the EQ Credit- Low-emitting Materials (for the VOC content)

Composition:

Bitumastic is a blend of rubber and high-quality bitumen carried in a hydrocarbon solvent to improve the application properties. Black in color and exhibiting a non-slump consistency it cures by solvent release, to form a tough flexible waterproof seal.

Application Insructions:

Surface preparation:

Surface must be free from all dirt, dust and loose material. Any oil and grease contamination must be removed completely. The surface must be made dry prior to the application of the sealant.

Masking:

Prior to application of primer and sealant, apply masking tape to the adjacent sides of the joints for getting a neat finish and to avoid the spilling over of the sealant on the edges.

Priming:

Under normal circumstances priming is not required. However, for very dry and porous surfaces, it is recommended to apply one coat of a solvent based bitumen primer (Polyp rime SB) *. Similarly, for joints subjected to continuous immersion, priming is recommended.

Application:

The sealant can be applied by means of a spatula or trowel. As the product is sol vented, it is recommended to mix the contents of the pail with a paddle mixer for a few minutes prior to the application to ensure a homogenous mix. Sealant application should start form the bottom of the joint/groove and continued to the top. Immediately tool the joint with the spatula or putty knife to smoothen and compress the sealant to effect total contact with joint surfaces. The putty knife shall be moistened with a cleaning solvent to prevent the sealant to adhere to the knife and ensuring a smooth and neat finish. Where masking tape has been employed to keep building surfaces clean, it is advisable to remove them at the moment the sealant filling is completed.

CURING Time:

The sealant cures on solvent release. The initial surface skinning will occur within 24-48 hour, however full cure depends on relative humidity. A 10mm depth of seal will typically cure within 14- 21 days @23°C @50% RH.

CLEANING:

Tools and equipment should be cleaned immediately after use with a cleaning solvent. Hardened materials can be cleaned mechanically only

STORAGE & SHELF LIFE:

The pails and drums must be stored in a covered, dry and shaded area, away from direct sunlight, UV and other sources of heat and protected from extreme temperatures. The shelf life of the product is up to 12 months if stored as per the recommendations. Excessive exposure to sunlight and UV will result in the deterioration of the quality of the product and reduce its shelf life.

HEALTH & SAFETY:

Bitumastic contains petroleum distillate, is flammable. Keep away from fire, sparks or other source of ignition. Wear protective clothing, rubber gloves, mask and safety goggles.
