Tensile Strength

Part 5: Tensile Strength in Epoxy Garage Floor Coatings. Tensile strength is the focus of Part 5 of our series, measured in pounds per square inch (psi), and it measures the resistance to breaking when pulled apart or “ripping,” a key factor in the durability of your epoxy garage floor coating in Toronto, Mississauga, Vaughan, the GTA, Scarborough, and Brampton. The testing is conducted in a specialized machine that pulls a sample apart, noting two critical measurements: the pressure required to pull and the elongation, which we’ll cover in more detail in our next posts to give you a complete picture for your residential epoxy flooring.

Durability Impact

Importance of tensile strength: A higher tensile strength suggests a more durable coating that can better resist equipment on its surface and other mechanical stresses, making it a vital property for long-term performance with concrete coating services. A high tensile strength often plays into good impact resistance and adhesion, meaning the coating will stand up to heavy objects falling on it and prevent delamination, which is crucial for industrial applications with epoxy flooring Toronto.

Industrial Needs

In industrial settings, you would want higher tensile strength to prevent premature floor failure that could disrupt operations across the GTA. These are the typical specs for some of the materials that we use: Epoxy/MVB at ~5,500/6,800psi, Polyurea at ~5,150psi, Polyaspartic at ~5,150psi, Urethane at ~6,250psi, and Polyurethane at ~3,500psi, offering a range of options. In most cases, you would want higher tensile strength to ensure the coating has a strong bond, as it measures the pull force—for example, high tensile strength is desired in crack fillers to help them stay bonded even when the substrate has slight shifts due to environmental changes.
