PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly constructed and prepared.
B.	If substrate preparation is the responsibility of another installer, notify Architect in writing of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	For Primer: Surface Preparation.
1.	Make sure surface is clean, dry, in sound condition, and free of any contaminants including oil, dust, grease, dirt, and silicone sealers. 
2.	Application Temperature: 45 to 104 degrees F (7 to 40 degrees C).
3.	Relative Humidity: 90 percent or less.
4.	Outdoor Applications:
a.	There is to be no rain or dew for 5 hours after completing coating process.
b.	Wind: May affect the finish quality. It may be necessary to erect a windshield. FP1 may be sprayed, rolled, or brushed. Best results and greater coverage are achieved when it is sprayed.
B.	For Coating: Surface Preparation.
1.	Metal: Surfaces must be clean, dry and in sound condition. Remove oil, dust, grease, dirt, and other foreign material from metal. Remove scale and light to medium rust using chemical cleaner. Heavy rust must be sandblasted or ground off.
a.	Field Check: Use a white rag with cleaner to wipe the surface to inspect surface condition. If rag remains white, your surface is clean. If rag turns dark or shows evidence of residue, clean away remaining impurities.
b.	New Iron and Steel: Sandblast, grind or otherwise remove 100 percent of slag from hot rolled steel, as surface tension of coatings adhere to slag and pull away from steel, causing delamination.
1)	If desired, prime bare metal with rust and corrosion primer per manufacturer's instructions. Apply single coat of T2 MCM after primer has cured per manufacturer's instructions. Be sure to follow primer manufacturer's application time to allow T2 MCM to anchor properly. If application window has passed, abrade the surface by sanding with 220 grit sandpaper to achieve suitable anchor system for the T2 MCM.
2)	If applying T2 MCM over steel or iron that has no primer, apply two coats of T2 MCM wet over tack no more than 15 minutes apart to ensure micropores are filled properly and completely.
c.	Iron or Steel with Existing Primer or Paint: Existing paint must be sanded down with 220 grit sandpaper or courser to get past any oxidation and to reach unoxidized paint layer. Sanding new layer is not necessary because it is already fresh paint. Re-paint as needed. Recommended: When re-painted areas are completely dry and cured, wipe surface with cleaner, followed by wipe-down with a damp rag with fresh water. Once surface is clean and dry, apply one coat of T2 MCM.
d.	Aluminum, Copper, Brass, Bronze, Galvanized Steel and Stainless Steel: Apply one coat of T2 MCM.
e.	Powder Coated Metal: Inspect surface to ensure there are no breaches in the powder coating. If breach discovered, re-coat or prime with matching paint to touch up area. Apply one coat of T2 MCM.
2.	Concrete: Surface must be clean, dry, and in sound condition. Remove oil, dust, grease, dirt and other foreign material. Surface that has retained oil must be completely free from further wicking action which will prevent a proper coating bond.
3.	Remove Silicone and existing coatings. Premera T2 MCM will not adhere to silicone or polymer-modified grout. Conduct a simple test to determine if surface previously sealed or coated, sprinkle water onto the surface. If water is absorbed and surface becomes darkens, it has not been sealed. If water beads, coating or sealer exist and must be removed before applying T2 MCM. Use appropriate cleaner to remove silicon or existing sealer. Rinse with fresh water and allow to dry until moisture content is below 13 percent (level of dryness required for coating bonding).
4.	Pre-seal unsealed or porous concrete with quality no-silicon sealers to prevent concrete surface from absorbing abundance of Premera T2 MCM, and rendering it ineffective. Recommended: Premera AT1 QSE.
5.	On concrete and porous substrates use Premera AT1 QSE to pre-seal porous unpainted surfaces first. Over unglazed ceramic or porcelain tile mix 25 percent Premera AT1 QSE with 75 percent Premera T2 MCM.
a.	New Concrete or Masonry: Inspect for sound condition. Clean surfaces of foreign material, dirt, dust, grease, oil, loose particles, laitance, sealers, curing or release agents. Rinse with fresh water and allow to dry until moisture content is below 13 percent (level of dryness required for coating bonding). Smooth surfaces should be abraded with 220 grit sandpaper, sand/bead blasted or ground with a floor machine. Test surface for proper ph (7 to 9).
b.	Previously Painted Surfaces: Inspect for sound condition. Clean the surface of all foreign material, dirt, dust, grease, oil, loose particles, or sealers. Rinse with fresh water and allow to dry until moisture content is below 13% (level of dryness required for coating bonding). If existing paint is peeling or badly weathered, repaint may be necessary. If re-paint is required proceed with that process outlined by the paint Manufacturer, then apply T2 MCM, following the paint manufacturer's cure time. If re-paint is not necessary, abrading paint to 220 grit before applying Premera T2 MCM.
3.3	INSTALLATION - APPLICATION
A.	Install in accordance with manufacturer's instructions, approved submittals, and in proper relationship with adjacent construction.
B.	Primer:
1.	Spraying:
a.	Sprayer Type: Portable alcohol and acetone-proof sprayer; grey or red tip.
b.	Sprayer Type: HVLP spray gun. Tip Size: 1.0. Pressure: 25 psi (172 kPa).
c.	Spray test-patterns: Elongated pattern 7.88 to 9.84 inch (20 to 25 cm) long and 5 cm wide in the middle with sufficient fluid to cover but not to puddle.
1)	Work with a waste bucket. Start and finish spraying in bucket and avoid drips on the surface being coated.
2)	When satisfied with spray pattern apply one coat to surface in a cross-hatch pattern to provide sufficient even coverage.
2.	Rolling: Use ultra-smooth high-density foam roller and apply FP1 as quickly as possible in a cross-hatch pattern. Do not press down on roller.
3.	Brushing:
a.	Use a good-quality brush. Choose size suitable for area being coated. Apply in a cross-hatch pattern.
b.	Do not over-work the coating.
c.	Keep lid on tin to stop evaporation.
C.	Coating:
1.	Over Primer: Apply single coat of T2 MCM after primer has cured per manufacturer's instructions. 
a.	Be sure to follow primer manufacturer's application time to allow T2 MCM to anchor properly. 
b.	If application window has passed, abrade the surface by sanding with 220 grit sandpaper to achieve suitable anchor system for the T2 MCM.
2.	Over Bare Metal: 
a.	If applying T2 MCM over steel or iron that has no primer, apply two coats of T2 MCM wet over tack no more than 15 minutes apart to ensure micropores are filled properly and completely.
3.	Application: Stir contents thoroughly to re-suspend nano particles that have settled to the bottom. 
a.	You may be a thick layer of sediment in the bottom of the container. 
1)	Sediment must be re-suspended in liquid to ensure coating performance. Re-stir every 15 to 20 minutes to re-suspend settling nano particles during application process to ensure proper performance of the coating.
b.	Spraying: Once surface preparation is complete and surface is dry and free of dust, begin application.
1)	Use a high volume, low pressure (HVLP) spray gun with a 1.0 to 1.3 size tip and pressure set at approximately 25 to 30 psi (172 to 206 mm). 
2)	Spray one coat in a cross-pattern; left to right, then up and down. This will provide sufficient coverage and will help prevent holes in coverage. 
a)	Exception for one coat is on unpainted steel or iron, which requires 2 coats wet on tack.
3)	Desired wet film thickness (WFT) is approximately 2.0 to 2.5 mils (51 to 64 microns). 
4)	b)Available in the paint department of major home improvement stores, or major paint store chains.
5)	To spray small pieces or tight locations, you can usea "Preval" sprayer. 
a)	This is a small disposable sprayer that can spray any liquid and holds approximately 6 oz (170 grams), which is ideal for touch ups. 
b)	Available in the paint department of major home improvement stores, or major paint store chains
c.	Rolling: Use a white, ultra-smooth high-density foam roller.
1)	Pour the Metal Coat into a roller pan and completely saturate roller. 
2)	Apply in a cross-pattern; left to right, then up and down as quickly as possible, since coating dries fast. 
3)	It gives a better looking finish if you avoid down pressure on the roller.
d.	Brushing: Use a good quality China bristle brush.
1)	Apply Metal Coat in a cross-pattern; up and down, then left and right. 
2)	To obtain best results, do not overwork coating, as it dries fairly quickly. 
3)	Do not bear down with the brush. Use light strokes using tip of brush to smooth out the coating. 
4)	Desired wet film thickness (WFT) is approximately 2.0 to 2.5 mils (51 to 64 microns)
e.	Dipping: Apply a blanket of nitrogen gas over coating in tank to prevent flashing of solvents and evaporation of product. Dip pieces and agitate back and forth and up and down and remove to dry rack.
