GUARDIAN-DOS™

FREEDOMTUFF® GUARDIAN-DOS™ is a group of integrative coatings utilizing an epoxy primer, spray applied freedomtuff® 2190 polyurea, freedomtuff® 4300 polyurethane intermediate coat and freedomtuff® 4000 polyaspartic topcoat that are hand applied a protective and elastomeric waterproofing with an overall theoretical dry film thickness between 80 mils± (2032 microns) to 140 mils± (3556 ± microns) used on concrete, frp panels, wood, metal and tile surfaces for showers and flooring. These coatings are 100% solids, solvent free and odorless, applied on vertical and horizontal surfaces forming a continuous seamless membrane.

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

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 4 – 7. Profile steel between 4-6 mils.

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. FreedomTuff® primer is required on all substrates, except on properly prepared steel.

MIXING

See Product Information Bulletin’s.

Do not mix partial containers of multi-component materials. Do not dilute under any circumstances.

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.

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.

Apply coating over primer within eighteen (18) hours, if not coated within the time allotted, contact Freedom® Chemical Corporation.

Allow Step One (1) primer to become tack free prior to application of FreedomTuff® FT-2190.

Prior to application of FreedomTuff® 2190 precondition both Part-A and Part-B to 75º F (23.88º C) – 80º F (26.66º C) before applying.

Adequately blend FreedomTuff® 2190 Part-B (Resin) making sure not to encapsulate any air until the mixture and color is consistent.

Fit Part-A with a desiccant drying device.

Apply FreedomTuff® 2190 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 170º F (76.66º C) each

Spray apply FreedomTuff® 2190 at a minimum of 4 (15.14165 liters) to 6.25 gallons (23.65882 liters) per 100 square feet (9.290 m²) to the substrate, to achieve a theoretical dry film thickness between 64 mils (1625.6 microns) to 100 dry mils (2540 microns) over the entire surface.

FreedomTuff® 2190 should be sprayed in a smooth pattern, to establish uniform thickness and appearance (crosshatch pattern).

Re-coat FreedomTuff® 2190 within 0 – 6 hours of previous coat.

STEP THREE: Application of FreedomTuff® 4300 must start within 0 6 hours of spraying FreedomTuff® 2190. FreedomTuff® 4300 Part-B should be mixed individually prior to combining, add Part-A to Part-B while mixing, using a mechanical mixer at medium speed making sure not to encapsulate any air. Mix until a homogeneous mixture and color is obtained (a minimum of 2 minutes is recommended).

Immediately pour the FreedomTuff® 4300 at 1¼ gallons (4.731 liters) per 100 square feet onto surface and spread evenly onto the FreedomTuff® 2190 in enough quantity to obtain 20 dry mils (508 microns), over the entire surface using notched trowel or squeegee then back roll using a ¼ “mohair roller with a phenolic resin core.

Prior to its full set and starting to gel, broadcast to refusal a washed, dry, rounded, contamination free 40 x 70 nominal sieve size sand (0165”/0.0083” millimeters) (400/210 microns) with 6.5 Moh’s minimum hardness into the FreedomTuff® 4300, or as required to achieve the specified slip-resistant finish.

Excess (loose) aggregate must be completely removed before application of the FreedomTuff® 4000. If shiny spots (no sand) appear in this area, re-apply FreedomTuff® 4300 and reapply sand.

Tile application: If applying tile over the FreedomTuff® Guardian-DOS™ coating skip Step Four (4).

Excess aggregate must be completely removed.

Do not apply more FreedomTuff® 4300 than can be top coated within twenty-four (24) hours.

Allow FreedomTuff® 4300 to dry prior to application of FreedomTuff® 4000.

STEP FOUR: FreedomTuff® 4000 is applied in two coats the first coat at a rate of 200 square feet per gallon (18.5806 m²), and the second coat at a rate of 200 square feet per gallon (18.5806 m²), for a total theoretical dry film thickness of 16 mils (406.4 microns) to achieve a desired color.

Coverage rates are approximate and vary based on type of substrate, porosity, roughness and size of broadcast aggregate. FreedomTuff® 4000 may require more than two coats.

Proceed with application of FreedomTuff® 4000 while air and substrate temperatures are between 40° F (4.4º C) and 104° F (40º C) and 25% Relative Humidity.

When FreedomTuff® 4000 is used as a top coat it must be applied within twenty-four (24) hours of the application of any Freedom ® Chemical Corporation’s products.

Re-coating FreedomTuff® 4000 the surface must be properly prepared and may require priming prior to re-coating.

DRY FILM THICKNESS

Freedom® Chemical Corporation’s Apply FreedomTuff® GuardianDOS™ coating with an aliphatic top coat is a theoretical dry film thickness between 80 mils± (2032 microns) to 140 mils± (3556 ± microns) without sand.
