High pressure water wash of 3,000 - 7,000 psi is also suitable. Apply a thin fi lm of Denso Paste, which serves as a primer. Spirally wrap the tape with a minimum 1" overlap. For severely corrosive environments, a 55% overlap is recommended. While wrapping, press air pockets out and smooth all lap seams.
Mix each of the base and hardener to an even consistency. Pour Part B (Hardener) into Part A (Base) and mix until an even color is achieved making sure all sides of container are scraped. Immediately begin applying mixed material onto surface with brush, roller or Denso applicator pad. Special attention shall be taken to ensure that there are no pin holes or low fi lm thickness areas. A second coat may be necessary
