Are Tamper Proof & Tamper Resistant Sealants Compatible With Cleaning Agents Used to Deep Clean Schools?

Over the last few months, we have discussed the way in which we operate our businesses will completely change moving forward. This includes the importance of ensuring and maintaining a safe environment for employees, customers, distributors, and carriers within our own company. Like Pecora, many businesses around the country are utilizing cleaning agents in their facilities to protect employees. The same goes for daycares, schools, universities, etc. who use these cleaning agents to defend our children against Covid-19.

Just like their parents who adjusted to a new working environment, as schools begin to reopen, students will learn to adapt to this new world. Many school districts are deciding whether to teach students virtually, face-to-face, or offer a hybrid option of both. A smaller school district in Eastern Pennsylvania has chosen to allow parents and students to choose between virtual or hybrid learning. The hybrid learning allows students to alternate every other day in the physical buildings. Every Friday will be the designated deep cleaning day. While students are all at home, the schools will deep clean classrooms, cafeteria, bathrooms, computers, etc.

In the majority of building projects, sealants are used solely to protect the building. However, when the building is a daycare or school, there is more at stake. It is important that the sealant cannot be pulled from a joint and eaten by a small child. Most caulking and construction materials are easily tampered with or “pickable.” in regard to sealants, pickable means the ability of the material to be interfered with to the point of removal, for uses other than what it was intended. In schools where idle “tampering” of a sealant can cause costly damage to a building or harmful to kids, security grade sealants are becoming an increasingly viable option to traditional caulks and sealants. All areas within reach of students, both exterior and interior, are potential locations where the use of tamper resistant and tamper proof sealants will result in significant life cycle cost savings.

In June, we highlighted our Pecora Joint Sealants and their compatibility with cleaning agents, degreasers, and detergents. Pecora joint sealants are routinely applied in interior applications such as a daycare or school. These sealants are subjected to periodic cleanings, even more so now, involving various cleaning agents, sanitizers, degreasers, disinfectants, and detergents. To ensure the joint sealants are compatible and acceptable for use in areas exposed to these chemicals, is it important for the applicator and sealant manufacturer to work together for a solution. Our tamper resistant and tamper proof (896-HIS, DynaFlex, DynaFlex SC, Dynapoxy EP-1200, & DynaTrol II) polyurethane, epoxy, hybrid, and silicone sealants are no exception to this compatibility.

Based on extensive field use, the following classes of cleaning product solutions are generally compatible with the aforementioned fully cured Pecora Joint Sealants:

  • Hydrogen Peroxide
  • Sodium Hypochlorite
  • Peracetic Acid
  • Acetic Acid
  • Alcohols
  • Citric Acid
  • Most Emulsifying Detergents

For any questions, Pecora Technical Service will review the specific cleaning solutions on a per project basis and provide written approvals for submittal purposes. Pecora Technical Service can be reached via email at or by phone at 1-800-355-8817.
