Winter version is designed to be used in 40 to 50 degree temperatures and recoat in a couple of hours. You can use it all year…it will just set quicker when its warmer. Poly Base 98 is a low odor, 98% solids, two-component polyurea designed as a base-coat/primer for high-performance coating systems. Customers love it for flake systems. Poly Base 98 has an extended open time which allows users to coat larger areas prior to broadcasting chips or quartz. Most people find that this product can be recoated in a couple of hours. Adhesion and broadcast consistency has also improved due to the longer open time. Poly Base 98 offers excellent elongation so it can be applied to multiple substances. Pigments can be added! This product is for base coats only (full flake, or base solid color where Poly 90/85 pigmented will go over the top )

Approximate Coverage Rate: 250 – 350 Sq Ft per Gallon

SURFACE PREP: The concrete surface must be deemed mechanically and structurally sound, completely clean, and dry. To achieve desired results, a mechanical grinding method should be performed with a 30 grit or coarser diamond to insure flatness of the substrate, remove surface impurities, and to profile the surface of the floor to a CSP-2.

Substrate and air temperature must be no less than 50° F and not exceed 80° F. If applied outside these limits the sealer may not achieve adequate film formation and may have excessive air entrapment, bubbles, blushing or hazing. Note that in direct sunlight, substrate temperature can exceed 150° F which can cause extreme bubbling issues.

MIXING: If mixing less than a full kit, mix Part A & Part B separately with a stir stick, low speed mixer or vigorously shake container prior to blending the smaller kit to ensure uniform distribution of all ingredients. Proper mixing is pertinent to application success. Pour a full pre-packaged kit of 2 parts A to 1 part B using a clean, dry working pot (mixing container). Drill mix contents approximately a minimum of 60 seconds…2 to 3 minutes is preferred. Avoid over-mixing or creating a vortex which could introduce moisture content to the mixture. No induction time is required prior to use, nor after mixing. If integrating anti-skid media agents, only do so after Parts A & B have been thoroughly mixed. Only mix up what can be used in 5 to 15 minutes. Many customers mix half of a 3 gallon kit at a time.

COVERAGE RATE: 250 – 350 ft per gallon *Coverage rates may vary depending upon surface porosity, texture, application method and prior sealer application. Excessive build up should be avoided.

POT LIFE: Expected workable pot life after mixing Part A and Part B is approximately 5-15 minutes at a common temperature range of 70°F – 80°F at roughly 50% relative humidity. Please note that higher temperatures and high percentages of humidity will shorten pot life, as colder temperatures and lower percentages of humidity will extend the coatings pot life. We do have different seasonal blends to help with set times.

APPLICATION INSTRUCTIONS: Application should be completed by rolling or a squeegee and back roll using a 3/8″ synthetic nap, phenolic core roller, or a lambs wool cover for pigmented, stained floors, or media coats. It is recommended to use only 18″ wide squeegees and rollers. If considering using airless application method, consult the manufacturer prior to application. Please note that the use of pump-up style spray bottle may create visible bubbles, blisters, and pinholes and is not recommended. Do Not Thin!

Polybase 98 must be re-coated within 12 hours. If beyond 12 hours, the coating must be sanded or screened with a 120 grit screen or equivalent. Failure to scarify beyond 12 hours may result in delamination and product failure.

FOR PERSONAL PROTECTION USE GLOVES, GOGGLES, AND RESPIRATORS.

PLEASE NOTE: Applying material outside the suggested parameters may result in product failure. It is always recommended to test the product in a small, inconspicuous area (on the same concrete substrate) for desired results prior to application. Coverage rates may vary for all coatings and substrates depending on porosity, density, texture, etc. When applying, do not exceed 400 sq. ft. per gallon. Applying too thin of a coating may cause inadequate film formation or performance expectations may be limited.

DO NOT USE ON BRICK. Basecoat only. Do not expose. This product should be completely covered in flake or a solid color.

Increased Temperature will shorten re-coat window. Decreased Temperature will lengthen re-coat window.

Question: How long do you have to flake in Poly Base 98?
Answer: Roughly 30 Minutes, the time can vary depending on several other variables like temperature, mixing times, and winter or summer blends.

Question: Is Poly Base 98 the best base-coat for a full flake system that has the quickest return to service?
Answer: Yes, Poly Base 98 is our contractor’s go to base-coat for a full flake one day system. Poly 90/85 slow (hyperlink) is a very popular alternative that gives you more time to apply.

Question: Can you use Poly Base 98 on a partial flake?
Answer: Poly Base 98 will amber if exposed and is not recommended to be used on a partial flake. Poly base 98 should be used as a base coat only and should always be completely covered by another color coat or media at 100% broadcast (ex. Flake) to assure you don’t see any basecoat. A polyaspartic such as Poly 90 or Poly 85 Slow would be best for partial flake base and topcoats as it can be exposed to sunlight and not be affected.

Question: Can you use Poly Base 98 all year?
Answer: Yes, we have a winter blend and a summer blend to adjust for temperatures. Winter blend is designed for 40-50 degree temperatures. Summer blend is designed for 75-95 degree temperatures. Winter sets up quicker than the Summer blend. We have customers that use the Summer blend all year and have tons of work time in the fall and winter. If you want to recoat in a couple of hours try to use the appropriate blend for the time/temperature.
