Bitubond

Rubber Duck Bitubond is a single component fibre reinforced bitumen-based, thixotropic heavy duty product for use on horizontal and vertical surfaces as a waterproofing and vapour barrier. Used in conjunction with a membrane to enhance the waterproofing system.

• Fibre reinforced: enhances the membrane's toughness, durability and flexibility

• Forms a watertight fibre reinforced system

• Heavy duty waterproof coating and vapour barrier

• Excellent adhesion to the concrete substrate that prevents lateral migration of underground water

• Can be applied to a damp surface

• Cured film is non-toxic

Smooth surface: 0.8 – 1 m² / litre per coat: WFT: 1000-1200 µm, DFT: 500‐600 µm, depending on surface porosity, profile and application tools.

Prime the surface with the suitable primer as suggested in SURFACE PREPARATION. Allow to dry.

STEP 1 - FIRST COAT

Apply one undiluted coat of Rubber Duck Sure Seal at a rate of 0.8 - 1 m² per litre. Allow drying for 6 hours before recoating. If used in conjunction with a membrane do not allow to dry and embed membrane whilst first coat is still wet.

STEP 2 - BEDDING (JOINTS, PONDS, DAMS & WATER FEATURES)

Thoroughly work the Geotexile waterproofing membrane (WP1100) firmly into the still wet first coat to obtain maximum saturation from below, smooth out all air pockets and creases. Ensure a minimum of 50 mm overlap on the adjoining lengths of the membrane. Allow to dry until tacky before applying the saturation coat.

STEP 3 - SATURATION

Apply a saturation coat of Rubber Duck Bitubond at a rate of 0.8 - 1 m² per litre to completely obliterate the weave and pattern of the membrane. Allow to dry for 6 hours before recoating.

STEP 4 - FINISHING

Apply a final coat of Rubber Duck Bitubond at a rate of 0.8 - 1 m² per litre. Allow finishing coat to dry for 48 hours before overcoating or 14 days before water exposure. If exposed to UV, Rubber Duck Bitubond must be overcoated with a suitable Promac top coat i.e. Rubber Duck Bituminous Aluminium.

Do not allow the product to dry on equipment. Equipment is readily cleaned using water. (Some detergent may be added to water to facilitate clean up).
