Product Description
RF-AU Aliphatic Urethane is a 60% solids, two component aliphatic polyurethane coating. RF-AU has excellent abrasion resistance, chemical resistance, hot tire resistance and UV stability. RF-AU is designed as a high performance top coat for concrete flooring systems.
KEY FEATURES & TYPICAL BENEFITS
- Excellent long term wear capabilities allow for longer life without re-coating.
- Enhanced chemical and stain resistance make this an excellent top coat in a variety of locations.
- UV stability allows this to be used in areas saturated by the sun throughout the day.
- This is an excellent top coat over Metallic Epoxy flooring systems.
- Can be tinted for solid color applications.
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. 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!
COVERAGE RATE:
First Coat - Direct to Concrete : 250 - 350 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: 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. 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. An airless or HVLP sprayer may also be used.
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 24 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.
