GUARDIAN-PW

FREEDOMTUFF® Guardian-PW Certified by Truesdale Labs as NSF/ANSI 61 for potable water applications utilizes an epoxy primer and FreedomTuff® 2210-PW™ a two-component spray applied 100% solids pure aromatic polyurea coating.  FT-2210-PW™ is flexible, abrasion resistant, impact resistant and forms a continuous seamless membrane of a desired thickness on concrete, metal, fiberglass and geotextile fabrics.  Its quick gel and set time allow for single or multiple applications without appreciable sagging and is relatively insensitive to moisture, allowing application in most temperatures.

FREEDOMTUFF® GUARDIAN-PW

PROFESSIONAL USE ONLY

Read and understand all the information contained in the Product Information Bulletin’s, Specifications, SDS’s and product labels prior to starting any project. Nothing contained in any of Freedom® Chemical Corporation’s materials relieves the end user of the obligation to read and follow the warnings and instructions for each of Freedom® Chemical Corporation’s products.

PREPARATION

Do not place coating over metal pan decks vented or unvented, split slab membranes, or other locations containing trapped moisture without prior written approval from Freedom® Chemical Corporation.

Concrete should be cured for 28 days (less than 28 days a Moisture Vapor Reducing primer maybe required) prior to product application and have at least 3000 psi compressive and 220 psi tensile strength.

Surface preparation is the essential first stage treatment of a substrate before the application of any coating. The performance of a coating is significantly influenced by its ability to adhere properly to the substrate material. It is generally established that correct surface preparation is the most important factor affecting the total success of surface treatment. Surfaces will be clean, dry, and sound, the presence of even small amounts of surface contaminants, dust, efflorescence, laitance, salts, curing compounds, dirt, oil, form release agents, and other foreign matter can physically impair and prevent coating adhesion to the substrate.

Shot Blast concrete between CSP 3 – 7.

Grinding is permitted only in areas that are inaccessible to shot blasting equipment.

COVERAGE RATE

Freedom® Chemical Corporation’s coverage rates for all products are approximate and vary based on type of substrate, substrate porosity, roughness and size of broadcast aggregate.

PACKAGING

See Product Information Bulletin’s.

PRIMER

Select appropriate primer from individual Product Information Bulletin’s. FreedomTuff® primer is required on all substrates, except on properly prepared steel.

MIXING

See Product Information Bulletin’s.

APPLICATION

Throughout the application the sanded surface must be clean and dry.

For optimum results proceed with application while air and substrate temperatures are between 32º F (0° C) and 104° F (40° C) 6º (-14.44º C) above the dew point and rising.

Prior to application of FreedomTuff® 2210-PW precondition both Part-A and Part-B to 75º F (23.88º C) – 80º F (26.66º C) before applying.

The substrate may require more than one coat of FreedomTuff® primer. After selection of primer, mix and immediately pour primer onto the substrate at a rate of 100 to 200 square feet per gallon (9.29030m² to 18.5806m² per liter) in enough quantity to obtain a minimum theoretical dry film thickness of 8 mils (203.2 microns) per coat.

Aggregate the primer with 0.125 pounds of washed, rounded, dry contamination free sand nominal sieve size #30-60.

Excess aggregate must be completely removed before application of the FreedomTuff® 2210-PW.

Do not apply more primer to substrate than can be coated with FreedomTuff® 2210-PW within eighteen (18) hours of application. If primer is not coated within the allotted time, sand and re-apply primer.

STEP TWO: Fit Part-A with a desiccant drying device.

Apply FreedomTuff® 2210-PW using a plural component, high pressure 1:1 ratio heated, spray equipment.

Proportioner Conditions:

  • Capacity minimum 20 lbs. per minute
  • Static pressure 2800 – 3000psi
  • Spraying pressure 2500psi minimum
  • Pressure balance 100 variance desirable
  • 300 psi variance maximum
  • Temperatures preheaters & hose 165º F (73.8889º C) each

Spray apply FreedomTuff® 2210-PW at a between 4 to 6 gallons (15.1416 to 22.7125 liters) per 100 square feet (9.290 m²) to the substrate, to achieve a theoretical dry film thickness of 72 to 104 (1828.8 to 2541.6 microns) over the entire surface.

When FreedomTuff® 2210-PW is applied in sections, each application must overlap the previous one within 0 – 6 hours by a minimum six (6”) to a neat straight line.

FreedomTuff® 2210-PW should be sprayed in a smooth pattern, to establish uniform thickness and appearance (crosshatch pattern).

Recoat window is within 0-6 hours of application, if not recoated within 0-6 hours, sand, prime and re-apply FreedomTuff® 2210-PW.

Freedom® Chemical Corporation’s FreedomTuff® 2210-PW has a theoretical dry film thickness of 96 dry mils (2438.4 microns) with primer (sand not included).

PRODUCT INFORMATION

See Product Information Bulletins for substrate preparation, packaging, coverage rates, primer, mixing and application information for each product selected.

FreedomTuff® products have a shelf life of 1 year from the date of manufacture, in factory-sealed containers.

DISPOSAL

All spilled material, unused contents of containers, empty containers and secondary containment spills/leaks, must be cleaned up and disposed of in accordance with local, state and federal regulations.

SPECIFICATION AND FIELD ASSISTANCE

Contact Freedom® Chemical Corporation for assistance.

Jobsite visits by Freedom® Chemical Corporation’s employees or its independent agents are solely for determining qualification for warranty.

TESTING

Perform an adhesion test prior to starting any coating project.

Substrate adhesion test should be performed seven days after application. All testing should be performed by a qualified testing agency. Freedom® Chemical Corporation is not responsible for testing.

TESTING IS REQUIRED FOR LEAK FREE WARRANTIES

Test the entire surface of the protective liner by spark testing at 100 volts per dry mil of lining thickness as per NACE Standard RPO 18B or ASTM D-1562 (steel) or ASTM D-4787 (concrete).
