Penetration CX TRANSCOAT 255 penetrates into concrete for a minimum depth of penetration of 2mm 
Water resistance   Repels rain water and inhibits ingress of surface water provided there is nohydrostatic pressure.
Permeability Permeability is low to water, salt solution, dust and soot particles. Leaching of soluble salts from brick work, which causes efflrescence, absorption of deicing salts by concrete  which causes degradation and absorption of atmospheric dirt by brickwork, concrete and stone are all minimized.
Water vapor release  CX TRANSCOAT 255 allows building surfaces to breathe naturally.
Application

Note: It is important to reseal containers after use to prevent deterioration of the product or evaporation. Any spillage should be absorbed with sand or saw dust.

Instructions

  • Preparation : Surfaces should be dry, although slight dampness is not detrimental. Surface to be treated should be free from oil, grease, loose particles, decayed matter and moss or algae growth. For this, cleaning with cleancrete mp is recommended. Joints in brickwork should be sound. If not, should be raked and redone with cement/sand mortar using CBSUPERPLAST IWC waterproofing compound.
  • Coating : Apply CX TRANSCOAT 255 evenly by spraying or brushing. Ensure an even coat over the entire surface. Porous surface should be well saturated with a two coat application
  • Decorating : Decorative coatings can be applied to surfaces previously treated with CX TRANSCOAT 255. Water based cement or emulsion paints should not be applied on coated areas. They can be applied before coating the surface with CX TRANSCOAT 255 coating.
  • Cleaning : Brushes and equipment should be cleaned with CHEMAX Florclean Sol immediately after use.

Estimating

  • Packaging and coverage : CX TRANSCOAT 255 is available in 1, 5 & 20 liter containers. On brick work and smooth cement renderings, 4.5 - 9 m2 per liter can be covered depending upon porosity of the substrate.
  • Storage Shelf life :CX TRANSCOAT 255 has a shelf life of 12 months if kept in a dry store in its original packing. High temperature and humidity storage may reduce this period.

Precautions

  • Health & Safety instructions : Contact with skin and eyes shall be avoided. Contamination with skin and eyes should be washed with water. CX TRANSCOAT 255 in liquid state is slightly toxic. Should be kept away from children and animals. Prolonged inhalation of the vapor should be avoided and adequate ventilation be ensured.
  • Fire : CX TRANSCOAT 255 is inflammable. Liquid vapor should not be exposed to naked flames. Smoking should be prohibited during application.
  • Flash point : CX TRANSCOAT 255: 380C
