2. To remove dust and debris from the surface

3. To mask off areas not being painted

4. To enhance the gloss of the paint

The correct answer is: To remove dust and debris from the surface

The primary purpose of a tack cloth in the refinishing process is to remove dust and debris from the surface before painting. During the preparation stage, it is crucial to ensure that the surface is clean and free from any contaminants that could affect the adhesion of the paint or cause imperfections in the finish. A tack cloth is specifically designed to attract and capture particles like dust, lint, and other small debris, using a sticky texture that holds onto these contaminants without leaving any residue behind. This step is vital in achieving a smooth and flawless paint application, ensuring that the final surface is as pristine as possible for the subsequent coatings. Using a tack cloth makes a significant difference in the overall quality of the paint job, as any leftover dust can lead to imperfections such as orange peel texture or uneven gloss levels. Thus, the function of the tack cloth is integral to preparing a surface that allows for optimal adhesion and a high-quality finish.
