BITUTAK MB SMOOTH

BITUTAK MB SMOOTH is a 150 mils (3.8 mm) heat-welded cap sheet membrane composed of a blend of APP (atactic polypropylene) polymers, select asphalts and a non-woven polyester reinforcement with a sanded surface. Membrane is film-backed for ease of heat-welding installation.


Benefits

  • Manufactured from a unique blend of APP (atactic polypropylene) polymers and select asphalts that enhances the weathering capabilities and UV resistance of the membrane
  • Reinforced with a heat resistant non-woven polyester mat which provides the strength and durability necessary in a roofing membrane
  • Adapts well to the use of aluminum or other fine coatings
  • Membranes are film-backed for ease of heat-welding installation

Surface Preparation

The substrate should be clean, stable, dry and free of any loose materials, or grease and contaminants, which will compromise the performance of the product.

Restrictions

This product can be applied directly only on non-combustible subtrates. A protection sheet such as RESISTO SEMI-RIGID ASPHALT BOARD needs to be covering combustible substrates (such as wood, plywood and OSB) before application of the product. Never apply this product over solvent-based materials. Keep away any combustible material from open flame. The product can be used as a cap sheet, but a UV-resistant coating needs to be applied uniformly on the sanded surface of the membrane after torching on substrate.
