One of the biggest advantages of epoxy floors is their strength and durability — but even the toughest garage coatings can show signs of damage if not properly protected from point loads. If you’ve ever parked a car with a jack stand on your epoxy garage paint floor and later noticed small circular indentations or shiny spots, you’ve encountered compression marks. These marks occur when heavy pressure is concentrated on a small area, slightly deforming the coating or leaving a visible impression.
The good news? Compression marks are completely preventable with a simple solution — jack pads. At Superior Garage Floors USA, we help Arizona homeowners protect their investment by understanding how epoxy flooring behaves under weight and how accessories like jack pads can preserve that flawless, showroom-quality look.
What Are Compression Marks on Epoxy Floors?
Compression marks appear as small, glossy circles or dull indents where an object has sat for a long time under heavy pressure. While the concrete underneath remains solid, the surface resin can slightly compress, changing the reflection or sheen. On darker metallic floors or high-gloss coatings, these marks are more noticeable under direct light.
Common culprits include:
- Car jack stands
- Motorcycle kickstands
- Heavy toolboxes on small casters
- Floor jacks left in one position for too long
- Metal furniture or equipment with narrow legs
Compression marks are not cracks or delamination — they’re aesthetic blemishes caused by concentrated load pressure. With the right precautions, you can easily prevent them.
Why Compression Marks Happen
Epoxy is extremely hard and chemical-resistant, but it’s not immune to physics. When heavy loads rest on a small contact area for long periods, the pressure per square inch increases dramatically. For instance, a 2-ton car supported on four 2-inch jack stands exerts more than 1,500 PSI at each contact point.
Even the best epoxy flooring systems — like Sherwin Williams epoxy paint floor or 100% solids resin coatings — have a limit. High pressure can slightly deform the cured surface or compress the flake texture underneath, especially during hot Arizona summers when temperatures soften the resin molecules.
The Role of Jack Pads
Jack pads are simple but effective tools designed to distribute weight over a larger surface area. By placing a pad under the jack stand or equipment leg, the load pressure spreads evenly, reducing the risk of indentation or surface deformation.
Jack pads come in various materials, including:
- Rubber – flexible, high-grip, and gentle on epoxy finishes
- Polyurethane – durable and chemical-resistant
- HDPE (High-Density Polyethylene) – rigid and ideal for heavy loads
- Composite or wood blocks – cost-effective for occasional use
At Superior Garage Floors USA, we always recommend using rubber or composite jack pads for residential garages. These pads protect the surface while maintaining traction so your vehicle or equipment stays safely supported.
Why Arizona Homeowners Need Jack Pads
Arizona’s extreme heat is a major factor. When garage temperatures rise above 100°F, even a professional-grade epoxy floor can soften slightly, increasing the chance of compression marks under static loads. Homeowners in Phoenix, Peoria, Mesa, and Goodyear know that summer heat can make garage surfaces hot enough to cook an egg — and that temperature affects epoxy’s surface resilience.
Using jack pads in this environment isn’t optional; it’s a must. They act like shock absorbers for your floor, ensuring the resin coating maintains its structure even under pressure and heat.
How to Use Jack Pads Correctly
Follow these simple steps to ensure maximum protection for your epoxy floor:
- Choose the Right Size: Select pads at least 6″ in diameter or large enough to spread the weight evenly.
- Inspect for Cleanliness: Ensure no dust or debris is trapped under the pad that could scratch your coating.
- Position Carefully: Place the pad before lowering your jack or stand — never slide metal directly on epoxy.
- Avoid Long-Term Loads: If possible, move heavy equipment occasionally to avoid long-term compression.
- Use Flat Pads for Level Support: Avoid pads with deep grooves that can concentrate pressure unevenly.
Additional Protection Strategies
Jack pads are just one part of maintaining a flawless epoxy surface. Here are other tips from our Arizona epoxy experts:
- Use Furniture Sliders: Under tool chests, workbenches, or freezers, sliders reduce wear and prevent marks.
- Opt for Thick Flake Systems: Our epoxy flake flooring adds texture and thickness, which helps resist minor surface pressure.
- Add a Polyaspartic Topcoat: A same-day epoxy flooring system with a polyaspartic finish provides extra hardness and UV protection.
- Keep Temperatures Stable: Using a garage fan or shade can prevent softening during extreme heat.
- Avoid Metal-on-Epoxy Contact: Even short contact from jack stands or steel legs can leave shiny marks.
Common Myths About Compression Marks
Myth #1: “High-quality epoxy doesn’t need jack pads.”
Even the best epoxy flooring can compress slightly under concentrated loads. Jack pads protect both high-end and budget coatings alike.
Myth #2: “Compression marks mean the coating failed.”
No — they’re surface-level impressions, not signs of failure. The underlying adhesion and durability remain intact.
Myth #3: “Heat alone causes marks.”
While heat softens epoxy slightly, marks only appear when heavy weight is applied in small areas. Both factors together are usually responsible.
Myth #4: “You can buff compression marks out.”
Unfortunately, once compression marks form, they can’t be polished away without resurfacing. Prevention is the best approach.
The Science of Load Distribution
The concept behind jack pads is simple physics — Pressure = Force ÷ Area. By increasing the contact area, the force per unit of area drops dramatically. For example:
- A 4,000 lb car on four 2-inch pads = 1,500 PSI per pad
- A 4,000 lb car on four 6-inch pads = about 170 PSI per pad
That’s nearly a 90% reduction in surface pressure, which is why even a thin rubber pad can make a huge difference.
Real Estate Perspective: Why Maintenance Details Matter

Homeowner Testimonials
Mike R., Glendale: “After installing my epoxy floor, I noticed marks from my jack stands. Superior Garage Floors explained compression and gave me jack pads — no more issues since!”
Tara N., Phoenix: “I park two classic cars on my epoxy floor. The team told me exactly how to prevent damage with rubber pads. It still looks perfect two years later.”
Jeff L., Mesa: “Superior’s crew used thicker epoxy and explained how to care for it. They really know their stuff — my garage floor looks better than most showrooms.”
FAQs About Jack Pads and Epoxy Floors
Q: What type of jack pad works best for epoxy?
A: Rubber or HDPE pads are ideal — they offer strength and slip resistance without damaging the coating.
Q: Can I use cardboard or carpet instead?
A: Temporary materials like cardboard can absorb oil or moisture, which may discolor epoxy. Always use non-porous pads.
Q: Are compression marks covered under warranty?
A: Most epoxy warranties cover adhesion and delamination, not cosmetic marks from improper load distribution — prevention is key.
Q: Can polyaspartic coatings resist compression better?
A: Yes. Polyaspartic and urethane topcoats have higher hardness ratings, which helps minimize indentations.
