When applying tape for mirrors, which method should NOT be used for sealing against condensation?

• A. Trimming the tape square
• B. Using double-backed tape
• C. Sealing with silicone
• D. Trimming the tape to a point

Answer: (A)

When installing mirrors and applying tape to seal them, trimming the tape square is not an effective method for sealing against condensation. A square cut edge can create a gap or edge where moisture may penetrate, which can ultimately lead to condensation build-up behind the mirror. In contrast, using double-backed tape provides a strong adhesion that allows for good sealing against moisture, and sealing with silicone creates a flexible, watertight barrier that is effective in preventing water from getting behind the mirror. Trimming the tape to a point can also enhance the application by providing more overlap and reducing the chance of moisture seeping in. Therefore, avoiding a square cut provides better protection and ensures a more reliable adhesion to inhibit condensation.
