ResinForce™ Polyurea 2:1 Primer 2H
98% Solids Polyurea Base Coat, Two Component, Mix Ratio 2(A):1(B)
Polyurea 2:1 Primer 2H is a low odor, 98% solids, two component polyurea designed as a base coat and primer for high performance coating systems. Polyurea 2:1 Primer 2H has an extended open working time which allows users to coat larger areas prior to broadcasting chips and quartz. Adhesion and broadcast consistency is also improved due to the longer open working time. This material offers excellent elongation so it can be applied to multiple substrate types.
Key Features and Benefits:
- Excellent Open Working Time provides more time for broadcasting media
- High solids provides great coverage and Low Odor
- Less than 50 VOC formula and non hazardous
- Excellent for use in Flake or Chip Floor Systems
- This Product is Tintable
- VOC Compliant for all areas in the United States and Canada
- Auto Service Centers
- Many other interior concrete floors where fast curing, high performance coating is necessary

MOISTURE TESTING: Concrete floors, especially those not poured over a proper vapor barrier (plastic), are subject to possible moisture vapor transmission which may result in bubbling and/or failure of high performance coatings. Basic moisture testing can be performed by placing a 4' x 4' sheet of plastic on the concrete surface and securely taping it down on all edges. If after 24 hours the concrete is still dry below the plastic, the surface should be ready to coat. If moisture is present, the coating applicator should perform calcium chloride and relative humidity probe testing to determine if excessive levels of vapor emissions are present before applying any coatings.
SURFACE PREPARATION: The concrete surface must be deemed mechanically and structurally sound, thoroughly clean of debris and completely dry. Concrete must be fully cured a minimum of 28 days. It is recommended to prepare the concrete surface by mechanical means such as shot blasting or diamond grinding with 30 grit or coarser diamonds to achieve a CSP-2 to CSP-3 profile. Vacuum concrete surface several times until dust thoroughly removed. If applying over an existing, fully bonded coating that is outside its recommended re-coat window, the surface should be sanded thoroughly with a 60-120 grit sanding screen until the surface is completely dulled with scratches.Vacuum dust thoroughly, rinse with clean water and remove excess water with a wet/dry vacuum or floor scrubber. Allow surface to dry completely prior to application of coating. Where applicable and with adequate ventilation, wipe the surface with acetone and a microfiber dust mop. CAUTION: Acetone is extremely flammable! If using acetone follow all safety precautions, make sure no pilot lights, open flames, sources of static electricity, sparks or extreme heat sources are present. Use recommended personal protection for acetone.
Substrate, air and material temperatures must be no less than 50'F and not exceed 80'F. If applied outside these limits the coating may not achieve adequate film formation and may have excessive air entrapment, bubbles, blushing or hazing. Please note that higher substrate, air and material temperatures as well as excessive humidity may speed the cure rate of this product. Cooler temperatures and lower humidity may slow the cure rate of this product.
FOR PERSONAL PROTECTION USE GLOVES, GOGGLES, RESPIRATOR AND OTHER NECESSARY PPE. REFER TO SOS PRIOR TO USE!
TINTING: May be tinted with polyurea tint packs, 32 oz. per 3 gallon kit is suggested for a solid, opaque finish. Always add color to Part A and drill mix for 2-3 minutes prior to blending A and B. Color may settle during long term storage and be difficult to redistribute. Always test for color acceptance prior to full application. Multiple coats may be necessary for total opacity.
MIXING: If mixing less than a full kit, mix Part A and Part B separately with a stir stick, low speed mixer or vigorously shake containers prior to measuring out the smaller kit to ensure uniform distribution of all ingredients. In a clean mixing container, blend 2 Parts A and 1 Part B using a drill mixer for 2-3 minutes. If mixing a full kit (except a 15 gallon kit), the Part A container can be used as the mixing container. Avoid creating a vortex in the material which could introduce air and/or moisture content to the mixture. Do not mix more than can be applied within the usable pot life time frame. DO NOT THIN!
First Coat - Direct to Concrete: 200 - 300 ft2 per gallon• Second Coat - Over Existing Coating: 250 - 350 ft2 per gallon•
- coverage rates may vary depending upon surface porosity, texture, application method and prior coating application. Excessive build up should be avoided.
APPLICATION: Recommended only as base coat under colored epoxy systems or full broadcast flake/quartz floors. Using a brush and/or 3/8" nap shedless roller, dip and roll the mixed material from a roller pan. 18" rollers are recommended for any surface to speed up application time and reduce roller marks. Start by placing the wet roller at one corner of an approximate 4' x 4' square and roll the material at an angle to opposite corner applying no pressure to the roller. Spread the material across only that square and immediately back-roll to even out material and roller lines. Adjust the size of your square as needed based on the amount of material being applied with the roller. After finishing the square, move on to the next square using the same technique. A squeegee and back roll technique may be used as well using a 5 - 7 mil notched squeegee and a 3/8" nap shedless roller. Always fill the roller cover in a puddle before beginning to back roll. While applying keep a wet edge to prevent roller marks. It is recommended to work in sections usually using control joints as dividers to ensure proper application results. Apply the mixed material within the usable pot life time frame. If the material becomes thick while applying and sticking to the roller, stop applying and discard the mixed material. At this point it has reached the end of the usable pot life. Do not allow to puddle! Use a brush to remove excess coating in joints.
Polyurea 2:1 Primer 2H 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 fisheyes, cratering, delamination and product failure.
RE-COATING: If possible, re-coat within the suggested re-coat window located on page 1. Apply additional coats in the same manner as the first coat. Note that higher substrate, air and material temperatures as well as excessive humidity may greatly reduce the acceptable re-coat window of this product. When working in higher temperatures, always re-coat as early in the re-coat window as possible to avoid failure between coats. If re-coating outside the suggested re-coat window (see page 1) or beyond 12 hours, sand using a 60-120 grit sanding screen to ensure adequate adhesion between coats. Vacuum dust thoroughly, rinse with clean water and remove excess water with a wet/dry vacuum or floor scrubber. Allow surface to dry completely prior to application of coating. Where applicable and with adequate ventilation, wipe the surface with acetone and a microfiber dust mop. CAUTION: Acetone is extremely flammable! If using acetone follow all safety precautions, make sure no pilot lights, open flames, sources of static electricity, sparks or extreme heat sources are present. Use recommended personal protection for acetone.
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, adhere to suggested coverage rates. Applying too thin of a coating may cause inadequate film formation, limited performance expectations and/or undesirable finish. Applying too thick may result to bubbling, hazing, etc. DO NOT USE ON BRICK.
