About Us


Preptech was formed in response to a growing need for an environmentally friendly and effective alternative for removing graffiti and renewing damaged, vandalized, or simply dirty surfaces. We use the SCHMIDT Accustrip soda-blast system with sodium bicarbonate blast materials and achieve superior cleaning without causing damage to the underlying surface or the environment.
