Isotex RUBB650

Rubberized Bitumen Protective/Waterproof Coating

Isotex-rubb 650 is a single-component, ready to use emulsified rubber modified bitumen coating with polymer and mineral fillers. It is suitable for applications to horizontal, vertical and inclined surfaces .It dries to form a black, flexible coating, which is odor and taint free.

Advantages/Features

  • Rubber like membrane capable of withstanding severe cases of expansion, contraction and deck movements.
  • Vapor proof barrier coating for interior & exterior floors & walls.
  • Excellent adhesion to most substrates.
  • It acts as a water proofer and curing membrane when applied to green concrete.
  • Liquid applied/Easy to apply with roller or brush.

Uses

Ideal protection system for concrete foundations basements, footings, retaining walls, bridge abutments, excellent vapor barrier for walls, floors, roofing structure, building exteriors and façade

Substrate Quality

The substrate must be clean, dry and free of all contamination such as dirt, oil, grease, coatings, etc which hinder an adhesion. The substrate must be sound and of sufficient strength. There should not be any standing water and should be a cured surface.

Substrate Preparation / Priming

It is recommended to use a prime coat to ensure proper bonding of subsequent coat. The prime coat can be prepared at the site by diluting isoTEX RUBB-650 with 20% water and applying this diluted coat as the primer. The primer penetrates concrete surfaces, fills pores, hairline cracks etc and produces an excellent surface for adhesion of isoTEX RUBB-650. Further coats shall be applied only after the primer coat dries off completely.

Application Method

Stir the contents of the drum thoroughly before application to remove all sediments. Each coat must be applied at right angles to the previous one to obtain proper coverage and uniformity. Be certain to examine each section carefully to ensure you’ve covered every minute crack and hole. Subsequent coats shall be applied only after the previous coat dries off completely Apply the rubberized bitumen coating @ 1-4m2/Lt/coat. Leave the coating for curing for a minimum period of 48 hours before applying any protection board or backfilling.
