UNDERSTANDING EPOXY FLOORING THICKNESS

UNDERSTANDING EPOXY FLOORING THICKNESS

Epoxy floors provide an array of different styles, colors, and customizations. However, epoxy floors also vary in thickness, and in most cases, this is overlooked. This is usually because not many people and installers are talking about epoxy floor thickness, so there is little information available about it. Most epoxy companies don’t even give you enough detail about their epoxy product thickness and how it affects your floor.

Some epoxy floors are engineered to be more resilient than others. Your workspace or residential needs should influence the thickness of your epoxy floor. In this regard, we are going to be discussing some factors that will help you understand your epoxy flooring thickness. Floor coatings are measured in ‘mils’ (a mil is 1/1000th of an inch). For example, one-eight of an inch equals 125 mils. Standard ‘home center’ floor paint when cured is about 2 mils. A sheet of standard copy paper is about 4 mils.

·         Thin Floor Coating

The thickness of these floors varies from 3-10 mils  based on the number of times it is coated, and if a top coat is used. These are perfect for floors that get standard foot traffic and lighter vehicle traffic. Primarily, they are only used to keep the surface of the floor shiny and clean.

·         High Build  Floor Coatings

These floors are often  self-leveling and run about 10+mils thick. For some industries, even a 20mm thick coating is not sufficient due to the use of heavy machinery, vehicles, forklifts, and movement of loads. In this case, the thickness may go as high as 250 mils (¼”)  and even up to ½” (500 mils). They use various layers of intermediate aggregates and screeds to build up these types of floors, and they are very expensive.

The general rule of thumb is the thicker the floor, the longer lasting, and the more expensive. One thing to remember is that if you go from a 10 mil floor thickness to a 20 mil, you need TWICE as much material and cost.

·         Is it an industrial-grade?

Most people find it difficult to know if their epoxy coating is industrial grade. Well, the simple way to find out is to check the abrasion rating. With this, you’d understand how the epoxy floor responds to foot and vehicle traffic. This lets you know how long the epoxy coating can endure stains and pressure without losing its gloss.

Abrasion is tested used abrasion meters which test a sample for wear.  The more ‘loss’ the sample has the less abrasion resistant it is. If the abrasion rating is high, then this means that the epoxy coating will wear out quickly. If the loss is low, then it is high abrasion-resistant.  Note that every small variation in the abrasion rating can make a large difference in wear factor.  vary from 4mg, 8mg, and 20mg to 24 mg. A floor with an abrasion loss rating of 24mg is not thick enough and could wear out quickly..

·         High Solids Epoxies

Epoxy floor thickness is also affected by the budget you have for your project. An example of such an epoxy is the Armorpoxy II high solids epoxy, which utilizes a topcoat with a nonskid wear additive called UltraWear.  The two-layer feature helps to keep costs to a minimum.

However, some epoxies are 100% solids systems which means that nothing evaporates out of the 100% solids epoxy. ArmorUltra is an example of this system.   These floors are extremely durable, and ideal for commercial/industrial environments. Our www.armorcladepoxy.com is also a 100% solids system designed for garage floors. It is more costly, but ideal for more demanding environments.
