Security Sealant Applications for Prisons
Vandalism in prisons costs taxpayers in the U.S. millions of dollars per year in maintenance and repair. In prisons and detention centers, safeguards are needed against inmates using construction materials to hurt themselves or others. Sealant has been “picked out” to be used as weapons, to expose joints for hiding contraband and weapons, and even to smoke. All interior joints and seams in areas where residents will be spending time in isolation should be specified with a tamper proof sealant such as Pecora Dynapoxy EP-1200.
Common areas such as day rooms, exercise rooms, and cafeterias where supervision is present should be specified with a tamper resistant sealant such as Pecora Dynaflex SC. Pecora Dynaflex SC is USDA approved for use in food processing and preparation areas although direct contact with food is not recommended.
Exterior applications where residents spend extended periods of time should also be considered for a tamper resistant specification. Exterior applications are designed around tamper and tamper resistant sealants of class 12.5 such as Pecora Dynaflex SC.
Why Use Security Sealants?
In the majority of building projects, sealants are used solely to protect the building. However, when the building is a daycare, hospital or prison, there is much more at stake. It’s important that sealant cannot be pulled from a joint and eaten by a small child, used by psychiatric patients to hurt themselves, or removed to expose a joint for an inmate to hide a weapon or illicit drugs. Security sealants contain the properties to prevent idle tampering and vandalism that can endanger children, patients and citizens. In addition to safety, the use of security sealants present many benefits from an economic perspective:
• Decreased risk of lawsuits
• Decreased maintenance costs
• Increased service periods of sealants
• Decreased replacement costs
“Tamper resistant” or “tamper proof” security sealants have been specifically engineered to offer enhanced hardness properties that distinguish them from typical construction sealants.

The theory behind tamper-resistant fasteners is to make a fastener whose loosening requires a tool that a tamperer is unlikely to have on hand at the time of opportunity for tampering. There is no expectation that it will be impossible for a tamperer to obtain the driver. Rather, the main idea is simply that most tamperers will not bother to seek out and obtain a driver. In the cases of vandalism prevention and theft prevention, since most vandalism and theft incidents are simply crimes of easy opportunity, the idea is to “raise the bar” and make the opportunity less convenient.
A tamper proof fastener takes the theory one notch further. Some tamper proof screws require a tool that is proprietary and can only be obtained with the purchaser submitting documentation as to its intended use. Others can be installed with standard wrenches, but when tightened to a specific torque head shears off, leaving a conical, round, or flat head design that completely protects your property.
