Surface to receive Chemical Resistant Epoxy Primer and Epoxy Floor Sealer Product #12 must be clean and sound. Remove all dirt, laitance, grease curing compounds and other foreign matter by sandblasting, mechanical abrasion. If acid etching is used follow with abrasive or mechanical abrasion. Remove water and dust from all surfaces with an oil free blast, or vacuum, immediately prior to application.


Temperature of Chemical Resistant Epoxy Primer and Epoxy Floor Sealer Product #12 must be 65 degrees F or above at time of mixing. Stir each component separately before blending. Mix two parts by volume of Part A with one part by volume of Part B for three minutes with a low speed electric drill motor equipped with a mixing paddle.


Chemical Resistant Epoxy Primer and Epoxy Floor Sealer Product #12  can be applied with brush, roller, trowel, airless sprayer or squeegee. Apply a coat of Product #12 to surface to be finished. Average application rate is 200 square feet per gallon on smooth concrete. Contact Epoxy.com technical support for information on how to adjust application rate to account for a substrate that is more porous, or has more texture. For more information before installing please see installation tips.

If anti-skid is required, or to improve trowelablilty of the next coat, it may be broadcast with aggregate (while epoxy is still wet). This can be done by hand or mechanical means. Allow them to dry. Then sweep off excess aggregate. Sand surface (if required) to desired texture. It may be left a final sealer or you may install other high end top-coats over the Product #12 at a rate as recommended by that material.
