After SODABLASTING what kind of prep work should be done before painting?

 

A through pressure washing is necessary to remove the soda residue before ANY coatings are applied.

This is very important; WATER is the only way to remove the baking soda.  Do not try to remove it any other way, it will not work and you may experience a coating failure.  We recommend a chemical called HoldTight 102 which when used properly will remove all Salts, Chlorides and Contaminates on the metal.  Even though pressure washing with clean water works fine to remove the residue, we recommend the use of this chemical due to the added benefits.  HoldTight 102 will give a window of 48 to 96 hours that will help prevent flash rusting.  Also when used properly it can increase the adhesion of you coatings by as much a 70%.  HoldTight 102 changes the surface tension of the water allowing it to flush out areas that normal pressure washing MAY not get into.  HoldTight works on most substrates; however on wood surfaces we recommend a citric acid or 1 part vinegar to 3 part water solution wash before applying any coatings.
