Frequently Asked Questions
What is an Epoxy Seamless Floor System?
Epoxy seamless floors are applied in 1/4 to 3/8 thickness as a protective aesthetic surface on concrete substrates. In light institutional floorings, they provide attractive looks, clean ability and good wear resistance. The system is an amine cured epoxy thermoset layer with suitable filler and pigments that cures in a proper time for quick back to service. Hotel hallways, bathrooms and food service areas are ideal candidates for epoxy seamless floors. Today’s technologies favor the use of cycloaliphatic amine curatives such as EC422 or EC430.

How do I formulate an Epoxy Floor?
Epoxy flooring formulas are relatively straight forward two package products of the liquid resin and curing agent. A third component will be the silica filler and mixture of fine and course silica and pigment. Some manufacturers prefer to pre pigment the resin portion to assure a good pigment mix in the system. A 2 to 1 ratio of resin to curing agent is the most preferred since it greatly minimized the problem of incorrect mix ratio.
For field use, the resin is packaged 3 parts to 1.5 parts curative by weight. The curative is then mixed into the larger container holding the resin. A portable mixer with paddle blade is use to mix thoroughly and then filler is added. The mix is free flowing and poured on to the substrate. A serrated trowel is used to spread the material and set application thickness by the height of the teeth.
Self-leveling epoxy floors. What are they?
Self-leveling floors consist of Part A diluted epoxy resin formulated with colorants and fine filler components such as silica flour. Part B amine curing agent and Part C courser fillers. A proper ratio of liquids (A&B) to Fillers (Part C) is 1 to 4. This makes for a flowable mix. A serrated trowel is used to spread the mixture and a spiked roller is used to accelerate de-aeration and avoid surface defects during curing. As a result self-leveling floors can be efficiently applied up to several hundred square feet per day.
The cured floor is ready for exposure to traffic 24 hours after application. This is determined by temperature conditions and the right selection of curative. EC422 is a curative of choice for this application in 55°F plus situations. Cooler ambient temperatures would require a faster curative (EC423) be blended in to assure a 24 hour return of the floor to traffic.
