ResinForce Water Based Urethane Matte - 1.5 Gallon Kit (Mix 2:1) Two Component
6100 WB URETHANE MATTE
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. Proper moisture testing should be performed prior to applying this product. 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 is thoroughly removed. If applying over an existing, fully bonded coating that is outside it's 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. Clean dust thoroughly.
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.
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. Up to 10% clean water may be added AFTER blending Parts A and B to help reduce roller marks, orange peel, etc. 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.
Coverage rates may vary depending upon surface porosity, texture application method and prior coating application. Excessive build up should be avoided.
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 4x4 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, more 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-coat with suggested window listed below. Refer to TDS for full re-coat information.
