Frequently Asked Questions

Do you have a machine that removes wood flooring, ceramic tile, or VCT?

Yes we carry several different size machines for this application. Please contact one of our branches with the dimensions and type of flooring and we can help point you in the right direction. If it is a large commercial site ask to have one of our salesman come to your site to give you recommendations.

How can I remove concrete coatings such as glue, paint, or thin set from my concrete floor?

One of the most common ways of doing this is with a concrete grinder. Now depending on the size of the area along with how thick of the coating will determine which machine you need and what type of diamond tooling.

Why Polish Concrete?

Polished concrete has many advantages: it is durable, easy to maintain, cost effective, dust proof, Leed friendly, has increased light reflectivity and is slip resistant, can be stained, stenciled and engraved to achieve a nice decorative appeal.

What Do I Need To Get Started?

We recommend that you have a complete surface preparation system including: a floor machine(s), vacuum system(s), diamond tooling, chemicals (densifier and sealer) and dyes (optional). It is also important that you have the proper training to ensure that your get your project done in a professional, timely and cost effective manner.

What Machine and Tools Do I Need?

Choosing the proper machine and tooling is critical for the success of the job, and you need to answer the following questions first:

  • Choosing the proper machine and tooling is critical for the success of the job, and you need to answer the following questions first:
    This will determine the size of the machine and vacuum needed, as well as how much tools you need. For example, a Lavina 20® Pro is great for small residential projects, like garages and patios, whereas for larger residential or commercial projects or time-sensitive jobs, you would need a bigger and more productive machine, like Lavina 25N® or Lavina 32® Pro
  • How Old Is The Concrete?
    If it is a brand new concrete floor, you have to give it at least 28 days to cure. If the slab is old, you may want to check it for pits and cracks, and use a special product, like the Quick Mender, to fill those.
  • What Condition Is The Concrete?
    The condition of the concrete will determine the initial grinding steps needed to prepare the floor for polishing including coatings, epoxy removal etc. If the floor is in great shape, you can start with 120 grit metals, but if the floor is uneven and blemished, you will need to start with a rougher grit like 30.
  • How Much Aggregate Do Want To Show?
    If you want to show aggregate, you have to grind the concrete more aggressively (longer and deeper) than if you want to polish just the cream.
  • How Hard Is The Concrete?
    If it is hard, use soft bond diamond tooling like the Nato® and T-Bone® resin pads. If it is soft, you have to use a hard bond tooling like the metal bond plates.
  • How Much Shine Do You Want?
    If you want just a honed finish on your concrete floor, you can stop after grit 220 or 400 but if you want a shiny mirror-like finish, you have to go through all the steps up to 3500 or 8500 grit. After V-Harr® Buff (8500 grit), the highest polishing step on the market, your floor will be sparkling.
  • Grinding Wet or Dry?
    Most people use the dry process – it is faster and less messy but you will need a good vacuum to take care of the dust.
  • Is Your Project Indoors or Outdoors?
    This will determine what sealer and dyes are needed. Lavina SPS Glow is for indoor use only. Water- and acetone-based dyes are also for interior applications only because color will fade over time in areas where the dye is exposed to frequent UV light. The Color Juice is ideal for concrete porches, patios, driveways, sidewalks and pool decks.
  • Do You Want Color In The Concrete?
    Color is entirely up to you but you would need the following accessories to apply the chemicals and dyes: microfibers mops and mop heads; air pump sprayers or a special pump sprayer if applying an acetone-based dye; painters tape and masking paper to mask off all areas that do not receive any color. Note: water- and acetone-based dyes are for interior applications only.
  • What Are The Electrical Requirements?
    Make sure you know what voltage your machine is before you plug it in the circuit. If you have a regular 220V machine, the Lavina Quick 220V system will help you put a 220V 20amp circuit in just about any house using 2 separate 110V outlets on different circuits. Never plug a 220V machine into a 480V circuit! If you have a high voltage machine you would need a special generator unless you have access to 480V circuit.
Can I Skip Steps?

It is important that you do not skip steps in order to achieve professional results.

How Many Square Feet Can Process A Day?

It depends on the condition of the concrete and whether you are exposing aggregates or polishing the cream only. Uneven floors and floors with epoxy that has to be removed takes much longer to process. The grinding portion of the job is the most time consuming, whereas the polishing steps go much more quickly.
