Remember to check the specification. Most likely it will state that the surface must be checked for contaminants, and blown down with compressed air prior to coating application. Protecting the newly blasted floor is important to ensure that coating failure does not spoil an otherwise profitable job. There are a number of ways to help eliminate contaminants on a newly blasted surface: 1. Sticky Mat Some contractors have been using a sticky mat at the entrance of their tanks. The workers simply wipe their boots on the first mat, then step on to the sticky sheets. This removes any final dirt and dust before they walk onto the new surface. When the sticky mat gets covered with contaminants just tear off the top sheet and continue the process. The mat is supplied in a pad of 100 sheets. 2. Overspray Shoe Covers You can supply overspray foot covers to all those who enter your tank to protect the newly blasted floor and keep the dirt from coming off their boots. This can become expensive and hard to monitor. 3. Non-marking Boots You can request all site personnel to wear non-marking boots. This eliminates the black marks left on the floor from the rubber soled boots and avoids contamination on the surface. It is a good practise to insist on the use of non-marking boots. It will certainly make the inspector happier and ensure you have a better quality project.
