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.

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.


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.
