What Are Floor Joists and Why Are They Important?

Floor joists are horizontal beams, used to provide structure and support to the subfloor and finished flooring. They are typically made of wood or steel. The spacing between these floor joists plays an essential role, how far they are placed have a direct impact on the strength and stability of your floor. Proper spacing between joists helps a lot when you are installing a tough coating like flake or metallic epoxy as it prevents sagging and cracking issues, giving a durable floor that lasts long. 

Standard Floor Joist Spacing

Wondering how far apart are floor joists? Well, the joists spacing depends on multiple factors like building codes, the kind of joist material, and for what floor will be used. Let's discuss some common spacings: 

• 16 Inches On-Center (O.C.): On-Center refers to the distance from the middle of one joist to the center of the next. This is a standard spacing for residential homes as it is ideal for household loads and supports most flooring types. 
• 24 Inches O.C.: This one is not very common but works best for lighter loads. It's mostly used in modern homes or light commercial areas. The joist material that is used here is mostly engineered wood or steel..
• 12 Inches O.C.: It is commonly used in commercial areas, where extra support is required as the joist spacing works great for high traffic areas. It is often found in old homes too.

Why Joist Spacing Matters for Concrete Coatings

Let's discuss why proper joist spacing is important for concrete coating: 

• Stability: Accurate spacing provides strength and stability. If the spacing is not measured properly, it might lead to bouncy or sagging floors, cracking even the toughest polyaspartic coatings. 
• Load Capacity: To support heavy loads, our coating systems need a solid foundation to perform at their best. Wider spacing like 24 inches may not hold heavy loads, such as gym equipment or vehicles in the garage.
• Longevity: Well-spaced joists make sure that your floor stays level, avoiding any stress on the coating, giving you a floor that lasts a decade. 

If your joists are spaced too far apart for your project, you may need to add more joists before applying the coating. Check out our blog page for more flooring tips and techniques.

Understanding your floor joist spacing is the key to a strong, durable coating. Before applying any coating always make sure that your joists are correctly spaced and in good condition. If repairs are needed, address them quickly to avoid issues afterwards.
