New initiatives in anti-terrorism require government buildings to protect personnel by making the building blast-resistant. Coating existing structures with polyurea spray on coatings is the best option because the elasticity of the polyurea coatings have proven to effectively contain debris in the case of an explosion, greatly reducing injuries and death from flying debris. The benefits of polyurea coatings are clear: it bonds to a variety of surfaces, it is ductile, easy to apply, and can be retrofitted into any existing building.
