What is the function of a tack cloth in surface preparation?

• A. Removing dust before painting
• B. Applying a primer
• C. Polishing for gloss
• D. Mopping with solvent

Answer: (A)

Removing dust before painting is the main purpose. A tack cloth is a lightly sticky, lint-free fabric that you use after the surface has been cleaned and wiped with solvent. The tackiness grabs and lifts tiny dust particles that lingering on the surface, which prevents those particles from being trapped in the wet paint. This helps avoid defects like dust nibs, fisheyes, or an uneven finish and allows the coating to adhere properly and lay down smoothly. Use light, even strokes and switch to a clean area of the cloth as it collects dust, then proceed with priming and painting. It isn’t meant for applying primer, polishing for gloss, or mopping with solvent.
