  • Applicable Scenario: This is particularly crucial before applying paint or finishing products, where surface integrity is paramount.

2. Choose the Right Protective Tape

Select a protective tape that suits your specific project needs, considering factors such as adhesive strength and temperature resistance.

Apply the protective tape evenly to cover the desired areas without air bubbles or wrinkles.

  • How to do it: Start applying the tape from one end and slowly press it down while unrolling, using a squeegee or credit card to eliminate air pockets as you go.
