Heavy Duty AG Epoxy Acid Shield

We recommend that the floor be cleaned and neutralized with TSP if its been exposed to acids or other caustic fluids. Then it should be either shot blasted or diamond grinded. This will provide the proper profile for the primer to permanently bond to. For small areas the Floor Prep Machine that can be rented from Home Depot does a good job. On larger floors of over 3000 sf we recommend renting a shot blaster or heavy duty grinder. For large areas rent the largest diamond grinder you can handle and ask for new 25 grit bits. You want to achieve a CSP 2 finished surface.

If acid etching we recommend two acid etches back to back with a TSP rinse after the second etch. To acid etch simply mix 1 gallon of muriatic acid with 3 gallons of water and disperse over wet floor at a rate of 300 sf per batch, scrub in with stiff bristle shop broom and let sit 3-5 minuts and rinse, repeat and disperse TSP powder onto wet etched floor, scrub in and then rinse thoroughly. Let floor dry 24-48 hrs until 100% dry. For very dirty floors we recommend increasing the strength to 2 gallons of water only per gallon of acid and or reducing area to 200 sf from 300 sf.

 Oil stain floors should be cleaned with Liquid Tide or Dawn dish detergent in combination with a diluted muriatic acid solution. Several applications may be necessary depending on heavy the stains are. Then neutralize with TSP rinse at 1lb TSP per 1000 SF. 

For heavily oil stained floors that won't come clean apply our Oil Stain Primer to form a bond to the oil soaked concrete.

For coating over a previous floor coating, sand the coating clean and apply our Bonding Primer to ensure adhesion between our epoxy and the existing coating.

Once the floor has been prepped, mix primer(front lable will be color coded and labeled Primer) Part & Part B per label mix ratio of 2:1. Use clear measuring cups to measure out an accurate amount of each part. Do not mix all at once, we recommend mixing a gallon of combine Part A & Part B for each person rolling. Mixing too much at once will result in the epoxy hardening in about 10 minutes which is not covered under warranty. If mixing more than a gallon, once mixed split the amount into two separate pails for each person rolling, this will slow the catalytic reaction. Apply as you would regular paint with a lint free 1/4" nap roller. Apply at approximately 290-300 sf/gal. Allow to cure 7-10 hrs before applying the topcoat but no more then 24hrs.

Next mix the topcoat(diffeerent color labels and marked Topcoat) in the same manner. Again do not mix all at once! Apply at approximately 100-115 sf/gal with 1/4" lint free roller. For best results after topcoat is mixed pour out in a bead directly onto the floor. When mixing be sure to run a drill mounted Jiffy mixer all the way to the bottom of your mixing bucket and all along the sides to ensure all the Part A & Part B gets mixed together. Allow topcoat to cure overnight for light traffic and at least 36 hrs before heavy traffic.

If using nonslip you can either mix it into the topcoat directly, we recommend using a roller pan when doing this. Keep stirring the topcoat to keep nonslip suspended. An alternate method is to broadcast the nonslip directly onto the cured primer and then apply the topcoat over it.
