BITUSEAL 1200

DESCRIPTION
BITUSEAL 1200  self adhesive membranes are produced with a special multi-layer design with a non woven polyester reinforcement which is impregnated and coated on both sides with a uniquely formulated elastomeric bitumen compound, which provides high adhesive properties. BITUSEAL 1200 is covered on its top surface with a translucent polyethylene foil and on the under side with a siliconised release paper. This combination provides instant adhesion with high tear and puncture resistance and improved tensile strength. A top surfacing of polypropylene film is also available. BITUSEAL 1200 DSA with double sided adhesive finish is also available for special applications. 

USES
BITUSEAL 1200  is the ideal membrane for dam proofing foundations, bridges, viaducts, and tunnels. It is recommended for use under composition shingles and roof tiles as a protective shield against water and ice. Strips of various widths are used extensively in road design and construction.

OUTSTANDING FEATURES
· Self adhesive
- Reinforced
- Easy to apply
                                               

INSTALLATION TOOLS REQUIRED
Knife, Measuring tape, Marking string, Small roller, Gloves.

APPLICATION
The surface to receive BITUSEAL 1200 should be smooth, dry, free from dust and dirt. the surface should be primed thoroughly with BITUMAT primer BITUSEAL 1200 is installed by progressively pealing off the release paper and unrolling the membrane along with it. The membranes, particularly at the overlaps should be firmly pressed down to ensure a good seal. For details of installation methods and flashing requirements, consult the relevant BITUMAT Design and Installation Manual.
