PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until the substrates have been properly constructed and prepared.
1.	Verify project site conditions under Section 01 00 00.
B.	If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.
C.	Coordinate with adjacent trades to ease construction process.
3.2	PREPARATION
A.	Prevent damage to substrate during preparation.
B.	Mechanically prepare concrete to ICRI CSP 3. Required CSP may vary based on the condition of concrete. Always adhere to International Concrete Repair Institute's current standards.
C.	Shotblast with mobile steel shot and dust recycling machine using a 50/50 blend of 290/330 shot. Remove steel shots with MAG-Broom and remove any leftover dust, debris, and loose particles using a dust collector vacuum with wand adapter. If using a small 110V shot-blaster, this step may need to be repeated several times by cross-blasting. 
D.	Edge Grinding: Grind all edges using an adjustable speed grinder to ensure all edges are clear of paints, sealers, and contaminants. Do not grind at high speed, as this may smooth out pores of the concrete and does not allow system to properly adhere to substrate.
E.	Cleaning and Dust Removal: Wear shoe covers. Remove all leftover dust and loose particles by using dust collector. Completely remove all existing coatings, oil, water, adhesives, dust, debris, and other substances that may impede system's adhesion.

3.7	CLEANING, CURING, AND PROTECTION
A.	Cleaning:
1.	Perform detailed cleaning at floor termination to leave a cleanable surface for subsequent work of other sections.
2.	Remove any spillage of cured and uncured materials from the site with a suitable solvent. Dispose of any temporary floor covering and leftover materials in accordance with federal, local, and building requirements.
B.	Curing and Protection:
1.	After completion of an application, do not allow traffic on coated surfaces for a period of 24 hours.
2.	Allow material to cure in compliance with Manufacturer instructions, taking care to prevent contamination during the installation and curing process.
3.	"Return to Service" means the system can be walked on. However, typical resinous coatings require 7 days at 70 degrees F to reach full cure. During this period, standing water, caustic chemicals, cleaning, or heavy traffic should be avoided as it may cause permanent damage to the finish.
