Isotex 100 Polyurathane

Polyurethane Based Liquid Waterproofing Membrane

isoTEXA 100 400  is a single component, VOC-compliant, unmodified Polyurethane waterproofing membrane that is applied as liquid. When it cures by humidity, maintains its elasticity, suitable for applications to horizontal, vertical and inclined surfaces. IsoTEXA 100 is with a special formulation of 100% polyurethane without fillers. 

Advantages/Features

  • Rubber like membrane capable of withstanding severe cases of expansion, contraction and deck movements.
  • Liquid applied/Easy to apply with roller or brush.
  • Highly resistant to oxidation, UV light and ozone because of unique additives used in compounding it. It does not crack.
  • Provides perfect resistance to water penetration.
  • Protect the structure from positive /negative pressures.
  • Excellent in abrasion, weather and corrosion resistance.

Uses

Ideal waterproofing system for concrete based built up roofs, maintenance of existing roofs, masonry and concrete walls, bathrooms, basements, bridges, decks, metal surfaces etc.

Installation

Surface Preparation

Surface to be waterproofed shall be dry, clean, sound and free of all contaminants which may interfere with adhesion or proper curing .The substrates should not contain holes or cracks and should be dust-free. All shrinkage cracks shall be treated with suitable material. Moving structural cracks greater than 1/16” (1.6 mm) shall be routed out and caulked with approved ISOCRETE material. Detailing like horizontal-vertical junctures, projections, expansion joints and other areas of potential high movement may require reinforcement mate and sealants to detail. Consult with ISOFLEX on site support for further information.

Mixing:

According to the construction consumption, the two components are mixed with a ratio as indicated and well stirred with a slow and stable speed mechanical mixer at least for 3 mins. The mixing container should be dry and clean.

Application

Before application, stir isoTEXA 100 by hand or using a mechanical mixer at slow speed. This rapid setting liquid is spread at the desired thickness onto the prepared surface. The coating is applied from the container using standard roofing brushes, squeegees or airless spray equipment at the recommended coverage rates on properly cleaned and prepared dry substrates. Application of the isoTEXA 100 System should be done in one complete step to create a smooth uniform self leveling surface without cold joints, lines or streaks. Apply the first coat at the rate of 500 micron thickness. Let it dry fully (approximately 4-6 hours should be waited between two layers), then apply the second coat (500micron thickness) .Waiting time shortens in hot weather and lengthens in cold weather.

Health/ Safety

Wear protective clothing, gloves and goggles.

Skin:- Avoid repeated or prolonged contact, if contact occurs ,clean with hand cleaner that removes oil or grease , then clean with soap and water.

Eyes- Contact could cause irritation. If contact occurs, flush with clean water.

Inhalation -Can cause dizziness. Remove to fresh air and if breathing difficulty persists, administer oxygen.
