Description

WB Prime FX is a 1:1 ratio, 41% solids, water-based epoxy primer. It has been formulated to be a low odor, two-component, water-based epoxy primer for interior use. WB Prime FX provides excellent substrate penetration and is a suitable primer for most epoxies, urethanes, polyureas, and polyaspartic polyureas.

Its low viscosity allows for excellent substrate wetting and penetration which provides a superior bond to concrete. That makes WB Prime FX an ideal primer for many coating systems.

WB Prime FX has a fast cure time and its low odor makes this a coating contractor’s favorite primer.

It also works well as a stand-alone, clear epoxy for interior applications. WB Prime FX has many priming applications suitable for most epoxies, urethanes, polyureas, and polyaspartics.

Can be used clear or tinted using WB Color FX.

Mixing

If mixing less than a full kit, mix Part A and Part B separately with a stir stick, or low-speed mixer to ensure uniform distribution of all ingredients.

If adding color, mix a 32 oz container of WB Color FX into Part A (Even if using less than a full kit) and mix thoroughly for 2 minutes.

In a clean mixing container, blend 1 Part 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.

Be sure to scrape the sides and bottom of the mixing bucket.

As a final mixing step, we strongly recommend placing the mixed (A and B) material in a clean bucket and mixing for an additional 1-2 minutes.

*Coverage Rates

First Coat – Direct to Concrete: 200 – 300 ft per gallon
Second Coat – Over Existing Coating: 250 – 350 ft per gallon

*Coverage rates may vary depending upon surface porosity, texture, application method, and prior coating application.

Application

We suggest using a shedless 3/8″ nap roller cover. Dip and roll from a roller pan. An 18″ roller is always suggested as it covers a larger area and helps prevent roller lines.

Start by placing the wet roller at one corner of an approximate 4′ x 4′ square and roll the material at an angle to the 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. 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 the material to puddle! Use a brush to remove the excess coating in joints. An airless or HVLP sprayer may also be used.

WB Prime FX will aid in completely sealing off the concrete surface and avoiding air bubbles.

Re-Coat

For best results, it is always recommended to re-coat WB Prime FX as soon as one can walk onto the surface without imprinting or making an impression on the surface. This is typically within 4 – 6 hours. (This is especially true when re-coating with Xtreme FX or Base Coat FX.)

If possible, recoat within the suggested recoat window. 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 recoat window of WB Prime FX. When working in higher temperatures, always recoat as early in the recoat window as possible to avoid failure between coats.

If recoating outside the suggested recoat window or beyond 24 hours, sand using a 220 grit or coarser 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 the surface to dry completely prior to application of the coating. Where applicable and with adequate ventilation, wipe the surface with acetone and a microfiber dust mop.
