Below are excerpts from an article written in September 15, 2020 issue of Concrete Decor magazine by Chris Sullivan:

Ever wonder where 21 square feet per bag or 300 square feet per gallon comes from? Coverage or application spread rates aren’t just a made-up number or educated guess. Determining coverage rates is always based on a mathematical constant known as the Theoretical Coverage Rate of a Coating. This in conjunction with surface conditions is how the rates are calculated.

According to, “The theoretical spreading rate or coverage of a coating is a function of the volume solids. The volume solids is the percentage of the coating consisting of binder and pigments which remain on the substrate, forming the final film after the volatile

Using this constant and the solids percentage of the product allows us to calculate the coverage rate of any material when applied to a smooth nonporous surface.components or solvents evaporate.”

A less technical explanation translates into how much of the actual solids of the applied product will remain and how far it will go once the volatile liquid portion evaporates. The mathematical part is based on the constant that 1 gallon of any 100% solids material will cover 1,604 square feet when applied at a dry thickness of 1 mil (1/1000th inch).


One U.S. gallon of sealer with 25% solids by volume will cover 267 square feet at a dry film thickness of 1.5 mil.

1,604 sq. ft. / 1.5 mil thick      X      0.25 solids      =      267 square feet

Most manufacturers will provide coverage ranges to take into consideration variations in surface smoothness and porosity. The smoother a surface the greater the coverage rate will be. The more porous a surface the lower the coverage rate will be. Understanding how coverage rates are established lets us better understand common decorative materials’ rate of application.

Cement-based overlays

Decorative overlays are treated like a 100% solids coating when it comes to coverage rate. In the case of microtoppings, the application is thin, with most ranging from 1/16 inch to 1/8 inch.

Coverage ranges from 200 to 400 square feet per 50-pound bag. The variation in coverage comes from the final thickness. It is usually determined by the top size aggregate (sand) in the mix.

Single-component acrylic sealers usually top out at 30% solids.  These are applied between 1 to 3 mils thick. Therefore, after working the math, you end up with 481 to 160 square feet depending on thickness.

Looking at a high-performance coating, like a 100% solids epoxy applied 5 mils thick, the theoretical coverage rate is 320 square feet. This is right between the 250 and 350 square feet most manufacturers state in their tech data sheets.

The big variable in all these applications is the surface profile and porosity. As stated earlier, the theoretical values are based on a smooth surface. Any roughness of the surface negatively impacts coverage rate.

Inside or Out

As the weather turns cooler, homeowners begin to look for ways to make the inside of their homes cozier and more attractive. CTi offers a number of looks for areas inside the home that are durable, easy to clean and beautiful. Compared to industry standard products, many times the CTi alternative can save the homeowner money as well.

Doing the Right Things

Always nice to be recognized for doing the right things, below is a review received by our Dealer, Concrete Design Solutions in Louisiana:

The work on the patio looks great.
I want to commend your employee ( I think his name is Brandon). The young man in charge…when others would take a break…he never stopped and asked over and over again for us to keep looking to make sure everything was to our satisfaction including colors.
He is an excellent employee. I would only want him to do my work in the future…..
Pat him on the back. He deserves it.

Virtual Reality

The Pandemic has created certain challenges for business people around the globe. A couple of the good things about the CTi Dealership is it’s considered essential and the application process allows the Dealer to keep the social distance needed. The challenge comes in how to present the product to the customer the first time. Some of our Dealers have gone virtual with this process, below are the tips they’ve provided over the last few months:


Before you meet with your potential customers, review the tips below so your virtual appointments will run smoothly. Also, include a brief run down to your customers on what they can expect on the call – some homeowners may not be as familiar with technology as you.


Many businesses, large and small, have turned to Zoom, GoToMeeting, or Google Hangouts to keep projects moving forward. To help you get a jumpstart, here are step-by-step video tutorials on how to use the platforms linked above.


Prepare your customers:

• Ask homeowners what virtual meeting software or app they prefer to use and try to accommodate and adapt to them. You can always give them options you’re comfortable with to choose from. (Our software suggestions are listed above.)

  • Schedule the meeting over the phone or via email. Send them an email calendar invite to confirm and remind them of the appointment.
  • Let your customers know to keep an eye out in their email for a link to the meeting invite. They should click the link and use the code given to sign into the meeting at the scheduled time.
  • Request photos of the existing deck, patio, or space where the new build will go. If measurements would be helpful, give detailed and easy-to-understand instructions of how to do so.
  • Suggest they browse to your website or Social Media pages so they will have a better idea of what they want the look and style of the outdoor living space to be.

 Prepare yourself:

  • Before the meeting, straighten up your meeting space, especially the area that will be on camera during your appointment. Homeowners want to see a professional, neutral space.
  • If needed, some software allows you to apply a virtual background that will cover up the area behind you. This is an opportunity to feature your logo or a beautiful, past build.
  • A reliable internet connection is crucial
  • Practice sharing your screen before the meeting.
  • Test the connection by calling someone from a different room in your house.
  • Be sure you have proper lighting so homeowners can see your face and the product samples clearly.
  • If you can, create a presentation ahead of time, so you have visuals you can share to the homeowners’ screen.
  • Go through your presentation to ensure a smooth experience while looking at your portfolio of past work and product samples.


  • Wear a branded shirt.
  • Share your screen and showcase your online reviews in real time, like on Guild Quality
  • Make it feel real by showing them past work or presenting a prepared rendering of their outdoor living space, if you have enough information to do so.


  • Send a follow-up thank you email that day or the following day to keep the discussion alive – and keep you top of mind.
  • Send a draft or rendering of their outdoor living space with the project proposal.
  • Get set up to have homeowners sign documents online. DocuSign offers a free 30-day trial.
