Self adhesive waterlines

A crisp, clean waterline tape is a fundamental aesthetic detail for any vessel. It not only visually defines the boundary between the hull and topsides but also enhances the overall design. Choose from a range of widths (15 to 80 mm) to perfectly suit your boat's size and style.

These self-adhesive tapes are engineered to withstand the harsh marine environment. Their formulation ensures excellent adhesion and long-lasting durability, even under prolonged exposure to UV rays and saltwater. Application is quick and easy, but proper surface preparation is essential for flawless results.

How to Prepare the Surface?

Before applying the waterline stripe, ensure the surface is clean, dry, and free of wax or silicone residue. Use a marine-specific cleaner and degreaser to remove any impurities. If necessary, lightly sand the area to promote adhesion.

Why Choose Self-Adhesive Waterline Tape?

* Easy Application: Requires no special skills or complex equipment.
* Precision: Allows you to create a sharp, uniform line.
* Durability: Resists weathering and saltwater.
* Aesthetics: Enhances your boat's design.

Frequently Asked Questions

What is the right width for my boat's waterline stripe?

The ideal width depends on the size and type of boat. Generally, it's recommended to position the waterline stripe approximately 5-10 cm (2-4 inches) above the static waterline (i.e., the line at which the boat normally floats). You can measure the height of the existing waterline (if present) or consult your boat manufacturer's specifications.

How do I correctly apply the adhesive waterline tape?

Thoroughly clean and degrease the surface. Apply the tape starting from one end and proceeding gradually, being careful to avoid air bubbles. Use a rubber squeegee to smooth the tape and ensure perfect adhesion. Finally, trim any excess tape with a sharp utility knife.

What products should I use to clean the hull without damaging the Gelcoat?

Use marine-specific cleaners formulated to remove dirt and grime without damaging the Gelcoat. Avoid harsh or abrasive products that could dull or scratch the surface. You can also use a protective wax to shield the Gelcoat from UV rays and saltwater.
