PART 3 – EXECUTION
3.01 EXAMINATION AND PREPARATION
A. Allow 28-30 days after completion of panel erection &/or concrete mansory wall for curing of concrete &/or
mortar.
B. Examination:
1. Examine substrate to which finely textured coating is to be applied. Do not proceed if unsatisfactory
conditions exist which hamper proper application.
C. Preparation:
1. Surface to receive system shall be free of defects such as honeycombs, form marks, tie holes, concrete
droppings, laitance, dirt, grease form release treatments, efflorescence, curing compounds, paint and other
foreign materials.
2. Remove all oil, dust, grease, dirt, loose rust, and other foreign material to ensure adequate adhesion, per
manufactures recommendations. Form release agents, hardeners, etc. must be removed by sandblasting,
shot-blasting, mechanical scarification , or suitable chemical means.
3. Fill all cracks, voids, holes in excess of 3/8 inch and bugholes.
D. Beginning of application means acceptance of substrate.
G. Tolerances: Finish coat must be pinhole free.
3.03 FIELD QUALITY CONTROL
A. Maintain schedule of application of system in field office for owners/architect's review.
