Husqvarna Grinders
Why Husqvarna Grinders Are the Gold Standard for Concrete Surface Prep in SoCal
Before any coating goes down, the slab has to be ready. Here’s why the right grinder makes every epoxy, polyaspartic, and urethane cement job look better — and last longer.
Ask any experienced floor coating contractor what separates a job that holds for 20 years from one that peels at year two, and the answer is almost always the same: surface preparation. You can pour the best epoxy money can buy over a poorly prepped slab and it won’t bond. The coating will fail — not because of the product, but because of what happened (or didn’t happen) before the bucket was even opened.
At Empire Coating Solutions, we’ve been supplying and installing high-performance concrete coatings across Southern California since 2000. Over those years, we’ve watched hundreds of jobs succeed and fail. The pattern is consistent: proper concrete grinding is the single highest-leverage action a contractor can take on any coating project.
And when it comes to grinding equipment, Husqvarna’s floor grinder lineup is our recommendation — for homeowners tackling their first garage floor, for professional contractors running full-time crews, and for everyone in between. Below we’ve broken down their entire current US lineup so you can find the right tool for your job.
The SoCal concrete problem
Southern California slabs come with their own character. Hot summers, dry heat, and decades of deferred maintenance mean the floors we work on are often sealed, contaminated, or just plain hard. Troweled concrete in older commercial properties can have surface laitance that looks solid until a coating fails to adhere. Garage slabs in the Inland Empire frequently have oil and tire marks ground in for years.
None of that is a problem — if you prep correctly. Mechanical grinding opens the concrete’s pores, removes surface contamination, establishes the CSP (Concrete Surface Profile) your topcoat needs, and gives the coating something to actually grab onto. Skip it, and you’re applying product to a surface that will reject it.
“Surface prep isn’t the unsexy part of the job. It is the job. The coating is just the finish.”
What makes Husqvarna grinders stand out
Husqvarna has been engineering concrete equipment for decades, and their floor grinder lineup reflects genuine R&D investment — not just rebadged commodity machines. Here’s what sets them apart for real-world coating applications:
Dual Drive Technology. Husqvarna’s planetary grinders allow separate control of the grinding head rotation and the individual disc rotation. That matters because different surfaces and diamond tooling respond differently. Being able to tune the relationship between those two axes gives operators precision control that single-drive machines simply can’t offer.
Planetary head design. Rather than a single spinning disc, planetary grinders use multiple smaller discs rotating simultaneously — both around their own axes and around a central axis. The result is a more even grind, fewer swirl marks, and better coverage on the first pass. For polished concrete and Superfloor finishes, this matters enormously.
Redi Lock and EZchange tooling systems. Switching diamond segments mid-job is friction that costs time. Husqvarna’s quick-change tooling systems let operators swap diamonds without reaching for a wrench. When you’re working through a 3,000 sq ft warehouse and the diamonds wear down, that’s not a minor convenience — it’s real money.
Sealed cabinet and head design. Concrete dust is abrasive, fine, and pervasive. Husqvarna machines are engineered with sealed grinding heads and electrical cabinets that keep dust out of the mechanisms. That translates directly to longer service life and lower maintenance costs — critical for rental fleets and busy contractor shops.
Built-in mist cooler systems. On mid-size and larger planetary models, an integrated mist cooler keeps diamond tools from glazing during heavy passes. This extends tool life significantly — especially important when working SoCal’s harder slabs.
Common platform across the lineup. All large floor grinder models share one unified platform. That means the same maintenance procedures, the same diamond tooling ecosystem, and the same operator experience across machines — making it easy to scale up your crew without retraining.
The full Husqvarna grinder lineup
Husqvarna currently offers 16 floor grinder models in the US market, spanning three categories: planetary grinders, single-disc grinders, and edge grinders. Here’s the complete breakdown — from entry-level rental units to remote-controlled industrial machines.

Diamond tooling: the half of prep most people underestimate
The grinder is the vehicle. The diamonds are the tires. You wouldn’t put bald tires on a race car and expect it to perform, and you shouldn’t run mismatched segments on a premium planetary grinder.
Diamond tooling selection depends on three variables: concrete hardness, the desired surface profile (CSP), and what you’re removing. Soft concrete needs harder bond diamonds. Hard concrete needs softer bond diamonds that self-expose fresh cutting edges faster. For thick coating removal, you want aggressive segments. For prep before a polyaspartic topcoat, you’re looking for a finer profile that the coating can still bite.
Husqvarna’s diamond tooling lineup is engineered to work with their grinder geometry, and we carry a full range in stock at Empire Coating Solutions. When you rent a grinder from us, we’ll spec out the right segments for your job — not just hand you a machine and wish you luck.
Prep, then coat — the right order every time
The coating products we carry — from our epoxy and metallic systems to urethane cement and polyaspartic topcoats — are engineered to perform on properly prepared concrete. They’re formulated with real adhesion chemistry, not forgiveness for bad prep.
That means the Husqvarna grinder and the coating product aren’t separate decisions. They’re one system. When you use the right machine, the right diamonds, and the right product together, the results speak for themselves: floors that don’t peel, don’t bubble, and don’t fail under SoCal’s heat and traffic conditions.
If you’re planning a coating project — whether it’s a two-car garage in Corona or a 50,000 sq ft industrial facility in the Inland Empire — come talk to us before you buy your materials. We’ll walk you through the prep, the product selection, and the application. That’s what we’ve been doing for 25 years, and it’s why our customers keep coming back.
