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.
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 4 – 7. Profile steel between 4-6 mils.
Grinding is permitted only in areas that are inaccessible to shot blasting equipment.
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.
See Product Information Bulletin’s.
Do not mix partial containers of multi-component materials. Do not dilute under any circumstances.
Throughout the application the sanded surface must be clean and dry.
For optimum results proceed with application while air temperatures are between 40º F (4.4º C) and 104º F (40º C). Insure that the outside temperature is at least 6º F (-14.44° C) above the dew point and rising. Apply while the outside temperature is descending, high or Low temperatures and humidity can significantly affect the cure time and pot life.
STEP ONE: 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.
Do not apply more primer to substrate than can be coated with FreedomTuff® 4300 within eighteen (18) hours of application. If primer is not coated within the allotted time, sand and re-apply primer.
Allow primer to become tack free prior to application of FreedomTuff® 4300.
STEP TWO: Apply 1¼ gallon (4.7317 liters) of FreedomTuff® 4300 at 100 square feet per gallon (9.290 m²) or in enough quantity to obtain a minimum theoretical 20 mils dry (508 microns); film thickness, immediately pour the FreedomTuff® 4300 onto the horizontal surface and spread evenly over the entire surface using notched trowel or squeegee.
Prior to its full set and starting to gel, broadcast to refusal a washed, dry, rounded, contamination free 30 x 70 nominal sieve size sand (.0232”/.600 millimeters, .0083”/.212 millimeters) with 6.5 Moh’s minimum hardness into the FreedomTuff® 4300, or as required to achieve the specified slip-resistant finish.
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® 4440.
STEP THREE: Apply ¾ gallons (2.839 liters) of FreedomTuff® 4440 top coat at 100 square feet per gallon (9.290 m²) or in enough quantity to obtain a minimum theoretical of 12 mils (304.79 microns). Immediately pour the FreedomTuff® 4440 onto the horizontal surface and spread evenly over the entire using a flat edge squeegee and then back roll using a ¼” mohair roller with a phenolic resin core.
FreedomTuff® 4440 should be applied in a smooth pattern to establish a uniform thickness and appearance.
Re-coating FreedomTuff® 4440 the surface must be properly prepared and may require priming prior to re-coating.
DRY FILM THICKNESS
Freedom® Chemical Corporation’s FreedomTuff® mechanical room with primer is a theoretical 37± mils (939.8 microns) dry film thickness without sand using FreedomTuff® 4440 top coat.
SAND OR AGGREGATE
Apply sand to refusal for the FreedomTuff® mechanical room deck for a slip resistant finish.
