When can you apply epoxy over an older coating? As long as the existing garage floor coating is a 2-part resinous product such as epoxy, polyurea, polyaspartic, or polyurethane, then you should be able to apply an additional coat of a compatible product without issue.
Can you apply polyurea over epoxy?
It’s fine to apply polyaspartic coatings on top of old epoxy-coated floors. They feature a strong intercoat adhesion with epoxy coatings. Your installer can apply a fresh coat of polyaspartic top-coat over old epoxy coatings that are still well-bonded to the substrate.
Which is better polyurea or epoxy?
As mentioned above, Polyurea is 4x stronger than Epoxy. It is also 98% more flexible than Epoxy. It is the flexibility of the material that makes it extremely durable and long-lasting. Polyurea is UV resistant, so it won’t fade or turn a sour, unsightly yellow in the sunlight.
Is polyurea stronger than epoxy?
With 98% solids, polyurea is 4x stronger and yet 98% more flexible than epoxy. It is highly elastic (300%) and will accommodate expansion, contraction and relative movement within concrete without cracking.
What should you not put on a epoxy floor?
Avoid using cleaning products with vinegar and citric acid. Citrus cleaners or vinegar can slowly degloss the epoxy finish. You should also avoid soap-based cleaners that can leave a hazy build-up on the epoxy floors. This film can also make the floor more slippery when wet.
Is polyurea better than epoxy for garage floors?
So, Which is Better: Epoxy or Polyurea? Polyurea is the clear winner. Because it’s more flexible, the material moves with the concrete (hello, earthquakes!). It’s also more impact resistant and is several times more durable than epoxy.
How long does polyurea last?
Finally, polyurea is very durable and long-lasting. This kind of coating can last up to 10 years and is a much less expensive alternative to other floor maintenance and restoration types. If you use polyurea to coat your garage floors, they will look brand new for years to come.
Why is polyurea so expensive?
Because it’s so flexible, the material can move with the concrete when there are major shifts in weight or temperature. Of course, all of this durability comes at a cost, and polyurea coatings are typically more expensive than their epoxy counterparts.
Is SpartaFlex better than epoxy?
SpartaFlex is an advanced, next generation 100% solids polyaspartic floor coating that gives your garage a beautiful finish that is 3x harder than epoxy, resists yellowing while also resisting permanent damage from hot tires. Perhaps best of all, SpartaFlex comes with a much better warranty than Epoxy.
Can polyurea be painted?
What kind of paint to use when going over polyurea? Generally, a good quality 100% acrylic latex house paint works well over sprayed polyurea. It is usually best to coat over the polyurea (sooner rather than later) within 24 hours of application.
Is polyaspartic harder than epoxy?
Today’s polyaspartic floor coatings are engineered to look better, wear harder and last longer than epoxy or polyurethane options.
What is the strongest epoxy adhesive?
The name of the world’s strongest adhesive is DELO MONOPOX VE403728. This is a modified version of the high-temperature-resistant DELO MONOPOX HT2860. This epoxy resin forms a very dense network during heat curing.
What is the most durable garage floor coating?
Epoxy is the most durable material available for coating tile flooring. Solid epoxy, which does not contain any solvents, can increase the strength of your concrete slab up to eight times. There are a variety of color options available, and you can also embellish the floor with colored paint flakes.
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.
Do epoxy floors 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.
How long will an epoxy garage floor 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.
What is better than epoxy for garage floor?
Nowadays, polyurea coatings are a much better option. Here at Garage Force, our patented polyurea garage floor coatings are about 20 times stronger than epoxy coatings. That is a huge difference in strength! In contrast, epoxy coatings will yellow and fade after consistent exposure to sunlight.
How strong is polyurea?
Polyurea is formed by reaction of diisocyanates and diamines, and it is one of the toughest synthetic polymer materials. These are some of its attributes: High strength with tensile strength higher than 5,000 psi and tear strength higher than 500 lbs/in. 100% solid with no volatile organic compounds (VOC)Aug 25, 2017.
Is polyurea coating toxic?
Polyurea coatings are made of isocyanates which are highly reactive, low molecular weight chemicals. According to the Centers for Disease Control and Prevention, these chemicals are powerful irritants to the mucous membranes of your eyes as well as your gastrointestinal and respiratory tracts.
What is polyurea used for?
Polyurea provides corrosion and abrasion protection of pipelines that carrying abrasive and corrosive materials. It is applied as a base coating to prevent cathodic disbonding. It is used as a pump coating to reduce cavitation and erosion, and to improve pump output.
How do you apply polyurea?
How to Install a Polyurea Concrete Coating, Step by Step Step 1: Prepare the surface. Removing laitance, sealers, and contaminants from the concrete surface is critical to the installation’s success. Step 2: Repair cracks and joints. Step 3: Apply the primer. Step 4: Roll the “bed” layer. Step 5: Apply the top coat.
