SDS- Polyapspartic Gloss & Satin

DIY EPOXY Polyaspartic is a 4 Hour Dry, two component, high-solids, Polyaspartic. The Shield’s extra working time, coupled with its UV resistance, mar resistance, and chemical resistance
will outperform most other types of sealers or topcoats.


Polyaspartic Shield is designed for professional use only and is specified as the finish coat for use in moderate chemical environments or in medium-heavy traffic areas. Apply Polyaspartic Shield as a coating over DIY Epoxy water base and 100% solids epoxies. POLYASPARTIC SHIELD can also be applied over decorative paint chips and can be used as a sealer on a variety of other substrates such as plain concrete, acrylic cements and Acid Stained Concrete Flooring. Use POLYASPARTIC SHIELD on Industrial Floors, residential Garage Floors, Decorative Floors, Restaurant Floors, Food Processing Facilities, Automotive Service Areas, and other moderate-high traffic areas.

Concrete must be clean, dry, and free of grease, paint, oil, dust, curing agents, or any foreign material that will prevent proper adhesion. The concrete should be at least 2500 psi and feel like
30-grit sandpaper. The concrete should be porous and be able to absorb water. A minimum of 28 days cured is required on all concrete. Relative humidity in the concrete floor slab should be
below 80% (per ASTM F-2170). All moisture should be kept away a min. of 72hrs before application and a min. of 72 hours after installation. This includes sprinklers, rain, fog, dew, etc. Before starting flooring work, test existing concrete slab to make sure there is no efflorescence or high levels of alkalinity. Alkalinity refers to a high pH reading which means the floor is not neutral. A high alkaline environment can cause salts to creep up through the cement called efflorescence. These salts have a tendency to prevent or destroy the bonding of coatings to the concrete. The most common form of testing is the use of a wide-range pH paper or tape. Make sure the floors pH reading ranges between 5-9 to ensure adhesion. The testing of concrete for alkalinity can show the amount of alkalinity only at the time the test is ran, and cannot be used to predict long-term conditions. Calcium chloride tests should be conducted to determine if the concrete is sufficiently dry for a floor coating’s installation. The calcium chloride tests should be conducted in accordance with the latest edition of ASTM F 1869, Standard Test Method for Measuring Vapor Emission Rate of Concrete Subfloor Using mAnhydrous Calcium Chloride. When running a calcium chloride test, it is important to remove any grease, oil, curing agents, etc. so accurate readings can be obtained. A rate of 3 lbs/1000 ft2/24hr period or less is an acceptable amount of vapor pressure the POLYASPARTIC SHIELD. If the reading is any higher, please consult your DIY Epoxy Salesman for further instructions. Failing to adhere to these strict guidelines can result in product delamination, discoloration, blistering, or all together failure of the coating system. Testing is the responsibility of the applicator. DIY Epoxy bears no responsibility for failures due to any of the above conditions.

Surface Preparation

Over Concrete: Concrete should be mechanically profiled by shotblasting or diamond grinding. When using other methods or scarification, make sure it is roughed to feel like 30 grit sandpaper and so that it is porous and contaminant free so the product can soak in and properly bond. Over Epoxy or CRU: Apply directly over new epoxy or urethane within 24 hours of initial application. When applying over existing epoxy or CRU that has been cured for longer than 24 hours, sand the surface with 100 grit sand paper, remove debris and wipe with acetone just before new application.


As Coating over Concrete, Epoxy, or CRU: Before application, POLYASPARTIC SHIELD (GLASS) A-Side and B-Side should be pre-mixed in their individual containers. Add 1 part of the A-Side
to 1 part of the B-Side while mixing, using a mechanical mixer (Jiffy Mixer) at low to medium speeds. No thinning is necessary. Mix until a homogeneous mixture and streak-free appearance is
attained (approximately 3 minutes). Use care to scrape the sides of the container to ensure that no unmixed material remains.


For best results, the material should be spread by squeegee or magic trowel and finished with a mohair roller cover. Neatly cut-in all edges with a brush and spread thin and evenly throughout surface to be coated. After spreading evenly, lightly back roll using a 1/4” solvent proof, non-shedding nap roller for smooth surfaces and a 3/8” nap for rough surfaces. Be sure to roll gently and evenly in a “V” pattern, rolling in both directions. Avoid over rolling as this may cause unwanted bubbles or roller marks. Avoid puddling, as material will turn white and bubble. Brush all puddles and expansion joints to avoid this problem. You have approximately 20 minutes to work with, as product will begin to “tack-up” as it begins to cure. Re-coat if needed within 24 hours of application to insure adhesion. If a delay occurs, it is recommended that the surface be sanded and wiped clean with acetone before reapplication.


Cleaning the Polyurea is best done by mopping surface with mild soap and water or a mild detergent. For best appearance, DIY Epoxy recommends resealing the surface every 3-4 years. Reseal by lightly sanding existing coating, cleaning surface, and applying polyaspartic over dry surface using above application specifications


• Do not apply in temperatures below 50°F or above 90°F.
• Do not apply unless temperature is 5° above the dew point or • Do not apply on damp or moist surface as it will whiten and
may cause delamination.
• Do not allow any BD Classic products to freeze.
• Always apply on a test area before starting actual job.
• Prior to coating previously sealed surfaces, do a small area
to test for adhesion.
• Shelf Life of this material is 12 months from the date of
manufacture. (See batch number for manufactured date)
• DIY Epoxy recommends the use of angular slip resistant
aggregate in all coatings or flooring systems that may be
exposed to wet, oily or greasy conditions. It is the contractor
and end users’ responsibility to provide a flooring system
that meets current safety standards.
• OK for use in residential garages in all districts of the United
• Please become familiar with local Air Quality laws and
regulations prior to applying this coating. DIY Epoxy bears no
responsibility for improper usage.
