AWR 2 & AWR 3 "Super Sealers"

Clear & Pigmented Acrylic Lacquers in Satin or Gloss for Concrete, Masonry, Paver, Roofing Tile & Aggregate Surfaces

Also for Interior/Exterior Pigmented Lacquer Artistic Use On Filled Wood, Metal or Masonry Panels

Product Description-VOC Compliant

AWR 2 & AWR 3 Series materials are water clear or pigmented 100% Acrylic solution surface lacquer sealers for exterior and interior use on concrete, masonry and aggregate surfaces. The AWR Super Sealer family repeatedly has been shown to be the highest performer of all the competitors in comparative testing in high, foot/vehicular traffic, steam cleaning resistance and food service for amusement parks (PIER 39), shopping centers, casino's, hotels and road use (Palm Springs Hwy 111 paver project). The resin has superior ultraviolet light resistance and does not yellow on exterior exposures. AWR is specifically designed for ease of maintenance due to its' ability to re-dissolve into itself when recoating after aging. Many enhancements have been made over the last 15 years that have dramatically increased AWR's resistance to water, soda drinks, common food stuffs, fuels, common acids & bases, water treatment chemicals, pool water & tanning oils, common vehicular oils & fluids, urine & other common body fluids and so forth. The film has superior resistance to foot and vehicle traffic and most water & solvent-borne common chemicals not listed above. Properly sealed surfaces have excellent food stain resistance. AWR can be tinted with solvent tints & is available in satin & medium gloss; colors include, clear, white, gray, terracotta, black (for asphalt), transparent "acid stain looks" and custom colors. PolyGrit™ can be added to AWR-3 for maximum traction where desired.

Decorative & Feaux Finishes: AWR is used as a pigmented lacquer system for creative artful designs on walls and floors - inside or out. These surfaces can be wood or masonry but must be properly prepared and filled for the look to be achieved. It is commonly used by artists for such applications on interior & exterior surfaces wherein several different coats are applied with transparent or partially transparent looks applied in layers. This work can be stunning and has been used in residences, hotels, restaurants and casinos. The "look of acid stain" can be achieved with our transparent automotive pigments with much longer life and easier repair than common commercial acid stains.

Broad Range of Product Uses

Decorative & uncolored concrete aggregate finishes, terracotta roofing tile, interlocking pavers, concrete, block, interior & exterior concrete floors, brick, driveways, precast exterior aggregate construction panels, stone, stucco, asphalt and patio blocks. AWR Is also used to restore or change the color of tile roofs, stamped concrete, driveways, garage floors, asphalt surfaces (maintains black color for years) & so forth.

Typical Projects

Driveways (asphalt & concrete), sidewalks, amusement parks (San Francisco's Pier 39), bathroom & restaurant floors, hotel entries, animal shelters/hospitals (Stanford Animal Hospital, Escondido Animal Shelter) parking garages, warehouses, loading docks, water treatment facilities, roadways (Highway 111 road base & sidewalks in Palm Springs), pool decks, concrete/fiberglass water slides, roofing tiles, stamped concrete surfaces, terracotta floor tiles & acid stained concrete surfaces, feaux/decorative wall & floor finishes (casinos).

AWR can withstand weekly or even daily steam cleaning when public use health safety issues are a concern as with situations at amusement parks, hotels or public places (frequent maintenance required in these situations).

Surface Preparation

Remove dust, grease and oily deposits. New concrete surfaces should be aged 60 days minimum. Interior & exterior concrete surfaces (particularly new) must be mechanically abraded (example - blast track, dust & cement residue must be removed) or acid etched with FSC Etch & Clean (phosphoric acid cleaner; must be neutralized with baking soda at 0.5-1.0 lb/100 sq ft concrete) to insure proper penetration & adhesion. The surface must be thoroughly rinsed (power wash is best) after etching & neutralizing to remove excess salts & debris. For stone, brick, slate, glazed tile or terracotta pavers, only use Tile & Brick Preparer.

When Etching: 1) DO NOT USE Muriatic acid or hydrochloric acid since they remain corrosive, leave poisonous residues (Calcium Chloride) and cannot be neutralized. 2) Plan runoff to prevent bleaching & etching of adjacent surfaces. 3) Use rotor scrubbers with nylo-grit pads for maximum etch and cleaning with FSC Etch & Clean. 4) If heavy oil residue present, use FSC Concrete Cleaner full strength before etching. FSC Etch & Clean cannot penetrate through heavy oil residue - it will only bead - providing no benefit for opening up the surface.

Surface must be thoroughly dry for 36 hours...use fans. If moisture remains, white spots and/or disbonding may occur due to activation of the water repellant. White spots may normally be removed with an AWR Thinner application, which redissolves the resin in preparation of another light AWR coat (sometimes 2 or 3 solvent treatments required). If white spots occur in heavy AWR build-up, sand off build-up down to substrate and reapply AWR. To be effective and prevent peel, AWR must penetrate into the masonry, concrete or asphalt matrix. Hard water deposits from landscaping water or regular hosings can leave a white film on surface (use FSC Etch & Clean with ScotchBrite Pad agitation for removal).

When Going Over Old Coatings : We always recommend complete removal of old systems as the ONLY sure way to get to a solid surface to penetrate into and to ensure long term adhesion when followed by proper surface preparation as described above. When AWR Super Sealer is applied over an old coating, it is at the applicator and building owner's risk. There is no way for FSC or AMTECO to stand behind such an application. Remember nothing sticks to old epoxies, urethanes or enamels so deep physical tooth is the only way to achieve any adhesion. If this approach is undertaken, machine grinding with 36-40 grit paper or grit blasting is required with all aggregate removed or sanded through. Always do test areas with adhesion pull tests before proceeding to a full project application. Even if the test and project appears successful, there is no way to be sure how long such an application will last - it could be 1 hour, 1 week or 1 year or much longer. So buyer, applicator or building owner beware of the risk that you are assuming by going over old coatings.

Application

AWR Series Sealers are 2 to 4 coat systems. Best to spray or roll apply in thin surface wetting coats. The first coat is intended to penetrate deeply and should almost disappear into the substrate. AWR-2SAL is the recommended primer coat for tight surfaces - especially smooth surfaces or lower permeability surfaces - to improve penetration & adhesion. Allow first coat to dry 2 to 4 hrs. The 2nd coat will re-dissolve the 1st coat & drive it deeper into the substrate. Do Not Leave Puddles On Horizontal Surfaces!!! A uniform light sheen should result after the second coat. A third coat may be required or desired if the surface is very porous (such as flat block, split face block or sandblasted surfaces). The porosity and temperature of the surface & substrate influence the amount of sheen & resulting surface wear characteristics. Porosity determines the amount of product required for each coat. 3 coats recommended whenever PolyGrit™ Non-Slip Aggregate is used to secure the aggregate particles for longer life.

Three coats must be applied whenever pigmented AWR Super Sealers are used (Clear AWR can be used as the topcoat). IMPORTANT NOTE: When Clear AWR is used as a topcoat over pigmented AWR, IT MUST BE SPRAYED to prevent modeling or uneven color. Pigmented AWR is best applied by spray to prevent roller marks if that is a concern.

For beadblasted or sandblasted surfaces, apply one coat of clear AWR 3 as a sealer coat prior to applying pigmented versions of AWR 3. Allow overnight cure for 1^st coat on extremely permeable surfaces to allow proper solvent escapement & film formation (especially for subsequent coats). 3 to 4 coats of AWR 3 required for beadblasted, sandblasted or extremely textured surfaces to fill profile (allow longer dry time due to deep penetration of AWR SSealer).

Changing Floor Colors With AWR : If previously applied AWR color is being changed (from grey to tan or light grey to dark grey for example), spray apply one coat of clear AWR 3 to isolate original color - allow to dry overnight or longer. Since AWR is an acrylic lacquer and redissolves upon subsequent recoats, the clear coat as an isolation coat is necessary to prevent color bleeding of the original color.

After the appropriate dry time, apply 2 coats (or more) of the new color to achieve the desired look. Always test an area first to ensure dry times and recoat times are appropriate to achieve the desired results. We recommend spray for all coats in this situation to prevent intermixing of the various layers & possible color modeling.

Equipment Application

AWR Super Sealers may be applied by spray, roller or brush.

1. Roller: Use 3/8" nap or 1/4" nap roller (must be chemical resistant woven cover, phenolic core). Work out of a paint tray or pour AWR directly on to work area. Only work each area with a couple strokes--PENETRATION IS QUICK WITH FAST DRY! Curing on the roller means the area is being over worked. Work roller in front of the body, not side to side.

2. Add FSC Retarder and/or ZR Thinner at recommended rates when surface temperature is 85°F & higher. Call FSC Coatings for instructions at 858-558-0800 or 800-579-8459.

3. Spray equipment & tools must be compatible with Perchloroethylene, Aromatic Hydrocarbons, Ketones, Acetone & Oxol 100 (Viton/Teflon seals & stainless steel parts required).

4. Spray Applications: Use standard airless or HVLP equipment with a 50% overlapping stroke. Slight sheen will show after application of satin; medium gloss when AWR3 Gloss is applied as the topcoat. Uniformity of sheen will depend on the uniformity of porosity and application technique. Recommended spray tip and pressure: 0.017 - 0.019 (6501 - 6502) tip orifice @ 900 - 1200 psi for airless applications. If dry spray is a problem, add Retarder per FSC instructions (800-579-8459).

Precautions:

1) Wear respirators when applying these materials. Do not smoke in area or apply near open flame due to flammability & hazardous combustion gases.

2) TEST AREAS: Always apply AWR Super Sealer to test area(s) before proceeding with full application. Testing especially important for sloped areas, surfaces to be recoated or color changed and tight, smooth surfaces . If AWR is applied in heavy coats then peeling, disbonding and premature wear patterns may result due to excessive surface build up. Do not apply to previously sealed surfaces other than AWR previously sealed surfaces, unless a test area is done before proceeding with AWR application.

3) AWR SUPER SEALER Is "Not" a waterproofing system. Water migration through stone or masonry surface can result in disbonding and efflorescence. Consider Silox-Seal or other alternatives prior to application for additional moisture control. If water migration and/or white salts are evident, use Calcium Chloride test to determine water migration rates for suitability of AWR on surface. Run tests during "wet season" if salt migration or water presence happens during heavy rains - otherwise test may give inappropriate low readings.

4) When Surface Temperature exceeds 85°F (ambient temperature greater than 70 degrees F or in direct sun), use ZR Thinner at 1 qt/gal AWR SUPER SEALER plus add FSC Retarder if necessary (and allowed in your area for emissions reasons) at recommended rates to slow down solvent evaporation and prevent solvent flashing. Do not apply above 110 degrees surface temperature. Check to see if is allowable in your area due to possible VOC impact.

Spread Rate

New Smooth Concrete Floors 200-300 ft² / gal

Old or More Porous Surfaces 150-200 ft² / gal

Stucco - Medium to light texture 100-150 ft² / gal

Very Porous Decking & Vertical Surfaces 100-150 ft² / gal

Quality Control : "Water Resistance Testing" is recommended. After 24 hrs of cure, flood AWR Coated surface with water to ensure water seal. Mark dark areas (where water has penetrated). After 24-48 hrs dry, apply AWR to marked areas & repeat test to ensure water seal.

Maintenance Recommendations: Given the variety of surfaces, ground water & landscaping water issues, hard water (calcium salts plus others) deposits, foot traffic issues, vehicular traffic, solvent/fuel exposures, quality of surface prep and so forth, regular cleanings with FSC recommended cleaners and AWR reapplications are required. General rule of thumb - residential reapplications every 2 years, commercial/industrial every 1-2 years. Touch-up around stairwells, high traffic areas, chemical treatment areas and escalators may be required more often.

Notes

1. Tinted materials will require more frequent maintenance coats than clears.

2. Allow test samples to age for 1 month for full evaluation.

3. Where maximum traction is desired, incorporate "POLY-GRITÔ " non-slip additive @ 5-7 oz. by volume of "POLY-GRITÔ" per gal of AWR. Mix "POLY-GRITÔ" into AWR-3 and stir w/drill motor. Apply mix with roller or spray with special HVLP. Apply 2-3 topcoats of AWR with "POLY-GRIT™" non-slip added over AWR primer coat for uniform appearance & to ensure hold for the "POLY-GRIT"Ô. Yearly and bi-yearly maintenance coats are required to maintain non-slip properties over time. For sloped surfaces -ALWAYS add POLY-GRIT™.

4. Will not stop water migration or efflorescence from underneath the surface.

5. Negative side water and edge water migration (as from landscaping sprinklers) can cause white spots and/or lifting & peeling of AWR. Use Calcium Chloride tests to determine water and/or vapor migration rates for AWR suitability.

6. Consider PRIME & SEALÔ and SILOX SEALÔ for sidewall sealing applications because of their superior vapor transmission rates and "breathability".

7. Do not apply in foggy or misty conditions or if rain is imminent or if humidity is above 85%--whitening, improper cure and/or peeling may occur if AWR is applied in these "wet" conditions.

8. Though not a problem to date, it is possible that "hot" tire marks could be left in material in applications where vehicular traffic is present. Do not allow car traffic on AWR for 5 days after applying.

Thinning & Cleanup

Thinning not required except during high temperatures. Thin with 1qt. ZR Thinner (VOC Compliant) per gallon AWR and appropriate FSC Retarder when surface temp exceeds 85 °F. Use ZR Thinner to clean equipment. When applying AWR over deep or dark colors (including asphalt or cured deep or darkly pigmented AWR coated surfaces), add ZR Thinner and FSC Retarder at ambient temperatures above 60 degrees F with direct sun exposure during application.
