Over the years nearly half of the technical service questions we're asked involve painting and varnishing epoxy coatings. More than anything else this has been the area that has caused most people trouble. We have solved these problems by developing our own paint and clear finish system for epoxy resin surfaces - more on this later.

Has excellent corrosion resistance and sealing properties. Highly alkali-resistant so there is no need for neutralization of new concrete. For very smooth floors, acid etch smooth surfaces to improve adhesion. Do this by mixing one 1 part muriatic acid to one 1 part water.
Important Mix well before using, Keep container tightly closed when paint is not in used. It is suitable for semi-conductor and electronic plants, food factories, pharmaceutical companies, automotive assembly plants, etc. Mixed with graded silica sand, it is trowelled on at an average thickness of 3 mm DFT SYSTEM C is for Medium Duty self-leveling floor coating system on concrete floors subject to light vehicle and pedestrian traffic as in garment factories, service stations, warehouses, parking buildings, restaurants, hospitals, and similar establishments.
It has the advantage of easier application and better weather resistance properties. For best results, recoating should be done overnight. For smooth surfaces, acid etch to improve adhesion.
Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted. Primer is a paint product that allows finishing paint to adhere much better than if it were used alone. Compared to paint, a primer is not intended to be used as the outermost durable finish and can instead be engineered to have improved filling and binding properties with the material underneath.
Two-part, high-solids epoxy primer is an ideal tie coat under high-gloss urethane topcoats to maximize adhesion, improve gloss, and aid in gloss retention. Dries quickly for faster overcoating, easy to sand once cured, and provides excellent corrosion control. The Surfacing Primer formula is ideal for faired surfaces. The High Build Primer formula provides superior filling capabilities.
One of the most common questions I get with epoxy floors is if it is necessary to prime the floor before applying the epoxy floor coat. Many contractors would like to avoid priming epoxy floors, as priming means at least an extra day of work as well as the additional cost of purchasing the primer products. Flooring professionals are actually divided over this issue, but let me just say that I belong to the Priming is necessary camp.
Epoxy paint usually comes in a two-part system, and when the parts are mixed, the result is a hard, smooth finish suitable for garages and other high-traffic areas. The smoothness and durability of epoxy are drawbacks when the time comes for recoating, however, and it isn't unusual for the new paint to flake or peel after it dries. You can prevent this by screening the epoxy surface with a floor buffer and sanding screen, then priming the epoxy and coating it with more epoxy or polyurethane. Sweep the floor, then mop it with a solution of 1 cup trisodium phosphate to 1 gallon warm water.
