Surface Profile Inspection Guide from SP1 to SP10

A surface profile of concrete or asphalt is a number associated with the material’s desired roughness or texture and its general appearance. It helps in determining if the surface is fit for a specific purpose. Roughness can be an indicator for:

  • Wear-ability
  • Friction coefficients
  • Performance in terms of cracks or corrosion
  • Adhesive properties

Our Surface Profile Inspection Guide helps in determining the desired surface profile of your concrete or asphalt and indicates the proper diamond tooling and machinery required for achieving it during the preparation process.

Surface Profiles (SP1-SP10)

The lower the surface profile (SP) number (SP1), the flatter the surface. An SP10 rating is an extremely rough surface. An accepted definition of surface profile is “the average distance from the peaks to the valleys of the surface, as seen through a cross-section of the prepared substrate.” The range of variation with your specific concrete slab, substrate or asphalt depends on its strength, composition, aggregate and finish. The final surface must allow for the secure mechanical bond of any sealer, coating or marking material, so make sure the surface is free of any dirt, oil, films, paint, coatings, cure, sealer and any other material before creating your desired surface profile.

[GUIDE] How-To Pair Your Concrete Equipment with the Proper Vacuum

One of the trickiest parts of choosing which vacuums you need on the job is determining which goes best with the equipment you already own, or the equipment you want to purchase. Based on voltage, water lift, amperage, etc. there are certain vacuums that are better suited to particular pieces of equipment. In order to simplify this process, below is a chart that outlines which equipment models are compatible with each Ermator vacuum and pre-separator duo. [Note: Ermator is our preferred dust extraction system.]

However, this is not an all-inclusive list – there are many equipment models not on this chart. So, if that is the case, let us know and we would be thrilled to pair you up with the proper dust extraction system. Also, be sure to check out our small grinder packages and large grinder packages.

Remove Residue Build-Up with 4 Proven Methods

Stoops Freightliner Mastic RemovalAre you working on the existing floor of an office, warehouse or department store? Old floor coverings leave behind surface residue such as glue, black mastic, rubber membranes, even thin-set materials and epoxy coatings that must be removed before you can revitalize the floor with a new overlay or polish.

Methods of Surface Preparation

Each floor brings with it a unique set of challenges based on a number of determining factors:

  • Condition of the floor
  • Type of surface residue
  • Concrete profile
  • Square footage of the job
  • Desired finished floor
  • Budget

After this initial assessment, contractors choose among several solutions for surface preparation, each with specific benefits and specialties for removing residue build-up. Below is an overview of the four most effective methods:

1. Grinding

  • Ideal for removing almost any coating or mastic, especially epoxy and glue
  • Ideal for large square footage

A Green Endurance Process Success with Cuviello Concrete

Cuviello Concrete - Howard County Middle SchoolCreating a polished concrete surface that is going to last over a long period of time, with little wear, long-lasting never-ending shine and well-preserved design is of course the ultimate goal for any polished concrete floor. However, actually attaining this is a different story. A unique concrete polishing solution, that addresses all of these desired outcomes, is the Green Endurance Process. This is a natural, yet customizable, approach with a focus on maximum durability and aesthetics. The process begins by working closely with architects to write in specs that are most conducive to the polishing process, eliciting the best results possible. Cuviello Concrete and Terrazzo Polishing is a large proponent of this process and integrates it into every job.

Recently Cuviello completed concrete polishing work at Howard County Middle School in Hanover, MD – a 23,250 square foot area. The corridors and cafeteria floor now feature cream and sand aggregate with multiple colors of dye in an elaborate design. What a head-turner! By using the Green Endurance process every aspect that effect the finished floor was controlled — mix design, placement, finishing, joint placement, the polishing process, protection and in service maintenance training.

The Green Endurance Process

  • Saw cut the pattern into the concrete
  • Fill the cuts with VersaFlex polyurea
  • Grind with 50 grit and 100 grit metal, 50 resin bond abrasive
  • Hone with 100 and 200 grit
  • Dye the floor with AmeriPolish Solvent Base Color
  • Densify the floor with Retro Plate 99
  • Finish honing with 400 grit resin bond abrasive
  • Polish with 800 and finally 1500 grit resin bond

Each bonded abrasive was fully refined from one grit to the next. At no time was any grit skipped.

Things to Keep in Mind

  • Understand exactly what the spec says and exactly what your scope of work includes and does not include
  • Educate, educate, educate your architect, owner and general contractor, and then manage expectations
  • Develop a TIGHT relationship with the division 3 contractor  be sure they understand what they are finishing is going to become the finished floor. Educate them beyond what the division 3 spec says and what is included in their scope of work.

Shining Moments

  • Successfully applied dye within the lines
  • Intricately saw cut the designs
  • Kept a consistent and steady work flow to accomplish saw cutting, joint filling, dying, densifying and polishing through multiple smaller crews

Getting to Know Husqvarna’s Dual Drive Technology™

When you hear “Husqvarna Dual Drive Technology™,” it may create excitement or apprehension, depending on your level of adeptness. Although making sense of this unique system may at first seem overwhelming, mastering your understanding will improve both production and performance. Thus, learning the intricate ins and outs can help you to best utilize your Husqvarna floor grinder, so pay attention!

The Essence of Dual Drive Technology

To begin, you should first know that this system comes standard only on models PG 820 and PG 680. Now, the key to understanding the Dual Drive system is that it provides versatility of movement, by allowing the operator to control the speed and direction of either the planetary head or the discs. This results in unlimited speed and directional combinations. For instance, the grinding discs can function in the same direction rotation or counter rotation.

Husqvarna Dual Drive Technology

The Unparalleled Benefits

Beyond this primary benefit however, there are other appealing advantages:

  • Allows grinding optimization for any application
  • Same direction rotation creates more friction on diamond tools – i.e. wider grinding width and higher productivity
  • Opposite rotation creates less friction on diamond tools – i.e. less powerful grinding and easier handling

Application Optimiziation

With these in mind, there are certain applications that are most ideal based on the setting you choose. This may not be surprising, but almost all applications can be applied using same direction rotation, and they are as follows:

  • Epoxy coating removal
  • Ceramic tile adhesive removal
  • Rain-damaged slab rectification
  • Flattening of uneven floors
  • Aggressive grinding of floor surfaces
  • Removal of thick contact adhesive
  • Lippage removal (stone and terrazzo tiles)
  • Resin bond diamonds, concrete
  • Resin bond diamonds, stone

However, counter-rotation also has specific applications it is well-suited for, including lippage removal, re-grouting of concrete floors (for Hiperfloor™ System) and both concrete and stone resin bonds. In addition, disc speed and planetary speed determine which applications can be best optimized. Refer to the chart below for those specifications:

Dual Drive Application Optimization

After delving into the essence of Husqvarna Dual Drive Technology™, the benefits, and application optimization, this complex but rewarding system should be clearer. This Husqvarna technology not only sets it apart, but it allows you – the user – to experience unparalleled control, power and a multi-functional range of applications. Begin putting your newfound knowledge to use now and you will see an increase in productivity and performance.
