solvent wipe-down and tackragging

163
Q

*** A solvent wipe-down must be done….

A

*****prior to the application of any primer or topcoat if the surface becomes contaminated after chemical treatment after scuff sanding operations, or if the coating needs reactivation.

164
Q

When performing a solvent wipe-down, what type of rags should be used……..only use a cloth to clean an area of..

A

clean cotton or cotton synthetic cloth

..10 square feet

165
Q

** What is Tackragging

A

**another form of wipe-down; is typically used AFTER an applied primer has cured

166
Q

When Tackragging what do you use

A

a cloth qualified to CID A-A-2522, Grade A, Color 1. very lightly spray with the finishing material being applied to the surface and then gently wipe the part being painted

167
Q

what are the first steps in preparing coating materials

A

check the shelf-life date and allow the materials to come to room temp

168
Q

what is “Viscosity”

A

a measure of a liquids resistance to flow. (slow or fast)
