Applying the epoxy to smooth concrete. It is essential for the primer and epoxy to be painted over a rough surface for proper adhesion to take place. Once applied, the epoxy itself will give the floor the smooth look that you expect.
Can I epoxy over smooth concrete?
The only valid reason why someone should apply epoxy on rough concrete is to eliminate dust and protect the surface from absorbing water or other chemicals. Epoxy is glossy and this will lead to all dents, cracks, holes and trowel marks of the concrete being revealed and magnified.
Does concrete need to be smooth before epoxy?
Epoxy Installation over Very Rough Concrete Floors Proper surface preparation is imperative to a successful installation of any epoxy. If the floor is excessively rough, in addition to proper surface prep above, it should be ground as flat as you can reasonably make it.
What happens if you don’t etch concrete before epoxy?
New concrete must be etched before applying the epoxy. The smooth surface of unaltered concrete won’t bind with other materials, such as epoxy or paint. As a result, epoxy will peel and lift away, failing to adhere to the surface.
Does epoxy stick to concrete?
Most epoxy glues for concrete come as two-part systems consisting of an epoxy resin and a hardener. When equal volumes of the resin and hardener are mixed, they react to produce a tough, rigid, high-strength bond. You can use epoxy resin for concrete to repair, fill, bond, and rebuild concrete surfaces.
What are the disadvantages of epoxy flooring?
Disadvantages epoxy floor Epoxy floors are hard and therefore there is contact noise during walking. Without underfloor heating an epoxy floor feels somewhat cold, similar to tiled floors. If there are unevennesses or cracks in the substrate, ripples can become visible in the floor.
Is epoxy self leveling?
Self-leveling epoxy is a coating applied to a slab of concrete and, as the name suggests, it’s easy to apply because it self-levels and spreads out across the flooring surface. While general epoxy coatings can also create a seamless floor, self-leveling epoxy leaves nothing to chance.
How clean should concrete be before epoxy?
Prepping Your Concrete Floor Before you apply any coating, you need a clean, dry floor without debris, moisture, cracks or holes. Give the area a thorough sweep. Clean up any grease stains with a degreaser and a stiff brush. You don’t need to remove all of the discoloration, just the greasy residue.
How Long Should concrete Cure epoxy?
Standard specifications recommend a minimum 28 day cure period for “green concrete”, before an epoxy floor coating or other resinous system can be applied.
How do you prepare a concrete floor for epoxy coating?
Instructions Clean and Degrease the Floor. Use a broom and wet-dry vacuum to clean debris from the floor. Etch the Concrete. Etch the concrete floor using the etching solution provided in the epoxy coating kit, following the manufacturer’s directions. Prepare the Room. Mix the Epoxy. Apply the Epoxy. Let the Garage Floor Dry.
Can you put a second coat of epoxy on garage floor?
Only one coat of EpoxyShield is needed on most concrete floors. If a second coat is needed / desired, it can be applied once the initial coat has dried. For the best adhesion, apply the second coat within 4 days of the first coat.
Does vinegar etch concrete?
Etching – Vinegar’s ability to dissolve CaCO3 will dull your marble, travertine, concrete and terrazzo surfaces. It may “clean” the surface but it is also dissolving pits into the finish and effectively dulling it. This will affect marble, travertine, concrete and concrete terrazzo surfaces.
What kind of epoxy do you use on concrete?
Two-Part Epoxy Floor Coating With 100 Percent Solids Two-part epoxy coatings offer the very best surface for concrete, a thick, hard, and attractive finish. These epoxy kits are often used with decorative chips that are sprinkled over the surface while it is hardening to provide a texture and attractive finish.
Does epoxy flooring scratch easily?
Epoxy floors are some of the hardest and most durable industrial floors on the market. That being said, they can still scratch, cut, or gouge if enough force is applied. Typical epoxy floors have strength of more than 10,000 psi.
What are the disadvantages of epoxy glue?
Lower bond strength than epoxies. Lower operating temperature range (max 125C) Moisture sensitive ingredients prior to curing. Ingredients can be hazardous to handle.
How long do epoxy floors last?
Typically, epoxy flooring lasts 2 to 3 years in heavy traffic. Commercial properties—like garages, restaurants, or factory spaces—with lots of daily foot traffic can expect this experience. However, with proper care and maintenance, your epoxy flooring may last much longer.
Is epoxy hard or soft?

How long does it take epoxy to self level?
The working timeframe for the epoxy before it cures and hardens is around 8 mins (lots of variables). If you have a large amount of mixed epoxy in your container, it’ll accelerate the chemical reaction because of the extra heat that the mix is generating and cure even faster.
How long after pressure washing concrete can you epoxy?
Sealer or Paint Applications Sealers range from 24 to 72 hours as a general rule, while epoxy paint applications to the etched areas of the concrete can take up to 10 days to dry in humid conditions.
