bituseal plastic is a hydrocarbon solvent-borne, asbestos-free, reinforced bituminous mastic.
bituseal plastic is a heavy duty mastic sealer and repair compound. bituseal plastic may be used to seal most roofing defects: sheeting laps, valleys, gutters, down-pipes, enlarged screw holes, to repair roof cracks, flashings, cracked tiles and patch repairs to tanks.
Advantages
- Economical waterproofing compound
- Easy to apply
- May be over-coated
Surface Preparation
All surfaces to be clean, dry and sound.
Bonding / Priming
Prime with a coat of bituprime, which should be allowed to dry prior to over-coating, except for steel which must be coated with a suitable anti-corrosive primer like 4 metal primer.
Mixing
Stir well before use.

Application
bituseal plastic may be applied by trowel, putty knife, extrusion gun or gloved hand.
bituseal plastic can be used in conjunction with a glass fibre membrane. The membrane must be set into the still wet film of bituseal plastic.
Cleaning of Equipment
Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.
Protection on Completion
Where the bituseal plastic is ultimately to be exposed to the effects of sunlight and ultra-violet radiation, it is recommended that, some 3 – 4 weeks after being applied, it be over-coated with silvakote®.
Temperature & Relative Humidity
| Application temperature range: | 5° C to 40° C, but material should be warmed to at least 10° C before use. |
