PRODUCT DESCRIPTION

An optimal blend of specially created acrylic binder and premium grade pigments combined with rheology modifiers and fillers, Chemistik HB-75 is an acrylic high build wall coating. This provides a tough, waterproof, durable yet flexible film which can breathe. Chemistik HB-75 is formulated to protect old and new painted or bare masonry walls for an infinite period of time. Ideally suited for exteriors of industrial, commercial and residential buildings.

ADVANTAGES

  • Adhesion : Due to its excellent adhesive property to masonry surfaces, HB-75 will not chip, flake or peel.
  • Flexibility: HB-75′s composition allows it to expand and contract with normal surface movement. Even under extreme temperature variations, it remains flexible, even as it maintains its toughness.
  • High build coating: With HB-75, a high build coating is attained. This helps to hide surface blemishes, hairline cracks, while preserving the architectural features of the building.lt also, protects the surface from atmospheric pollutants, thus making it extremely durable.
  • Resistance: HB-75′s formula creates a tough barrier which resists dirt pick up, growth of fungus, algae, mildew, dry rot, moss etc. Importantly, it prevents hydrolysis which decomposes the film due to water exposure.
  • Vapour permeable: Though water resistant, this tough and flexible film permits transmission of water thus allowing the walls to breathe normally and thereby increasing its life.
  • Easy to apply: Being single component coating, HB-75 can be easily applied with rollers/trowel thus eliminating the need for skilled labour.
  • Attractive and economical: Soft texture designs in a choice of selected shades make HB-75 a very attractive option. And once applied, little or no maintenance is required. Hence, HB75 is economical, too.

METHOD OF APPLICATION

  • HB-75 to be applied with roller/trowel. To get a softer texture, use our special rollers.
  • Apply HB-75 coat on prepared surface with rollers using just enough hand pressure to attain a uniform soft texture and moving roller in one direction only.
  • For other designs as per roller designs, the method of use would be to trowel the material on prepared surface attaining a thickness of 300-400 microns. Allow it to touch dry. After which the roller should be moved to attain the design. Move roller in one direction only and occasionally dip into water to provide lubrication.
  • Where second coat is recommended, follow the above precautions. However, move roller at right angles to the first coat. Recoat interval should not be done more than 8-10 hours between each coat. For normal application, only one coat is recommended.
