Airless Spray: Output fluid pressure at tip 1500 psi, Tip Size: 9-11 thou (0.23- 0.28mm)
*Spraying is not recommended as this method can result in excessive application, which can result in a powdery surface causing disbondment of subsequently applied paint coatings
If spraying, it is advisable that equipment should be cleaned/flushed during the course of application, to prevent attack of the equipment by this acidic product
Brush or sponge application is recommended
An even black film should result if the reaction has occurred correctly
If the surface is uneven in colour, lightly abrade, thoroughly degrease by solvent washing and re-apply
Remove any excess product by solvent washing before applying a paint system
