Direction for use

    Surface Preparation
  • Surface Preparation
    Surface preparation is of great importance and will affect the degree of adhesion and life of the coating. The surface should be sound, dry, free of oils, greases and dust. The new concrete mortar / plaster should be cured for minimum 28 days. Lattice and loose particles can be removed by light sand blasting


Application

1. Apply one coat of TECHOXY, water dilutable epoxy coating as a Primer Coat &
    allow it to dry for 6-8 hrs.
2. In case the surface is very rough, apply Techoxy white cement putty. TECHOXY
    putty can be prepared by mixing of 1 ltr. TECHOXY with 2 Kg of white cement and     water. Allow putty to cure for minimum 24 hours and sand it lightly by fine emery     paper No. 320 to a smooth surface. Clean the dust by clean & dry cloth. Mix     component A & B as specified.
3. Apply first coat of TECHWALL ULTRA by brush or spray.
4. Second coat should be applied at the intervals of 6-8 hours.
5. Allow the coating to cure for minimum 72 hours before exposing to the working     conditions.

DRYING & CURING TIME SCHEDULE AT 30° C

 Surface dry time
:
15-20 minutes
 Intercoat application
:
6-8 hours
 Hard dry time
:

24 hours

 Complete dry
:
72 hours minimum


Cleaning
Tools and equipment should be cleaned with Xylene, Toluene, Acetone or Ketone solvents.

Precaution

  • Some people are sensitive to resins, hardeners, solvents & its vapours so it is advisable to use hand gloves, goggles & mask.
  • While application, proper ventilation should be provided.
  • Avoid application below 10°C temperature of surface.
  • At low temperatures, drying & curing periods will be prolonged.
  • Avoid application on damp or moist conditions, as it will create blister formation problem.
  • Shelf life of the unmixed materials is one year from the date of manufacture
  • Storage store at cool & dry place


Shelf Life - One year from the date of manufacture.
