Best Methods & Techniques for Painting Industrial Floors

A new floor polymer floor offers commercial, retail, industrial and institutional environments a variety of benefits including a beautiful appearance, high-performance and durability. Are you looking to paint or refinish your industrial or commercial floors? Not sure what the best method is to install a resinous floor? Professional polymer floor installers use a variety of methods. Today we’ll discuss four different installation methods.

Trowel Applied Flooring

This method uses hand-troweling (using a flat bladed trowel) or power-troweling to install aggregate-filled polymer mortars. The aggregate is applied as a single mortar blend. Typical application is 3/16ths to 4/16ths of an inch in thickness.

General steps for trowelled application:

  • Prime
  • Screed
  • Apply material with trowel
  • Apply topcoats as necessary

Broadcast Applied Flooring

Similar to troweling, broadcast applications use a liquid resin and aggregate component. However, unlike troweling, the two are applied separately in alternating layers. Examples of aggregate components include Colored Quartz or Colored Chips.  Typical application of each layer is 1/16th of an inch in thickness.

Steps for broadcasting application:

  • Prepare substrate (Note – any floor imperfections must be properly corrected or they will be visible through broadcast floor)
  • Apply primer
  • Apply basecoat and broadcast aggregate
  • Sweep off loose aggregate after basecoat has cured
  • Apply a second basecoat and broadcast aggregate
  • Sweep off loose aggregate after final broadcast is cured
  • Apply grout coat to seal aggregate

Slurry Applied Flooring

Slurry is another common technique for installing resinous flooring. It is economical and a great way to add strength and wear into any floor. In this case, liquid resin is combined with powders and/or aggregates and applied as a fluid mixture. Typical application ranges from 1/8th to 3/16ths of an inch in thickness.

Basic steps for a slurry-applied floor include:

  • Prepare substrate (including any crack repairs)
  • Prime
  • Apply slurry mix with notched squeegee
  • Apply optional topcoats

For floors that require additional thickness, a broadcast floor may be installed on top of the slurry.

Resin Only Flooring Application

Unlike slurry or broadcast floors, resin only floors do not contain fillers, resulting in a thinner cured finish. Final thickness ranges from 13 mils to up to 32 mils.

Installation of resin only floors requires:

  • Prepare (including crack repair)
  • Apply primer
  • Apply topcoats as needed

Choosing the right application method for installing your resinous floor depends largely on the desired result and overall environment of your floor. Consult with a knowledgeable polymer flooring specialist to provide you with the best method for your particular flooring needs.
