What is ALEXSEAL SURFACE PROTECTOR and why choose it
ALEXSEAL SURFACE PROTECTOR is a professional, water-based, one-component coating that cures into a flexible, tear-resistant film. It is designed for the temporary protection of fully cured painted, glass or stainless steel surfaces during construction, storage, assembly and transport of yachts. The protective film helps prevent light scratching, soiling and weather influences and can remain intact for up to 6 months under proper conditions.
Thanks to its light blue color, easy spray or roller application and clean peel-off removal, SURFACE PROTECTOR offers a controlled, traceable way to safeguard high-value finishes without permanent alteration. The product is intended for professional use only.

FAQ
-
What type of product is ALEXSEAL SURFACE PROTECTOR?
It is a water-based, single-component coating that dries to a flexible, peelable film for temporary surface protection.
-
Which surfaces can I protect with this product?
It may be applied on fully cured topcoat surfaces, as well as suitable glass and stainless steel surfaces, after proper cleaning and testing.
-
How long can the protective film stay on the surface?
The tear-resistant film is designed to remain intact for up to 6 months; it should not be left on a freshly painted surface longer than this period.
-
Can I use it on unpainted gelcoat, polycarbonates or wood?
No. The technical data sheet states that it should not be applied over unpainted gelcoat, polycarbonates or wood.
-
How should I apply ALEXSEAL SURFACE PROTECTOR?
It can be sprayed in one coat to 150–250 µm WFT (75–125 µm DFT) or rolled in 2–3 coats to about 100 µm DFT, following the specified equipment settings and film thicknesses.
-
Do I need to mix it with a hardener or thinner?
No. It is a single-component product that only needs thorough stirring. It must not be reduced.
-
How is the film removed after use?
Once fully dry, lift an edge and peel off the film, preferably between 10 °C and 32 °C, with best results between 18 °C and 24 °C.

Section 8 – Personal protection measures
Exposure controls
- Provide good general and/or local exhaust ventilation to keep solvent vapor concentrations below applicable occupational exposure limits.
- If ventilation is insufficient to maintain safe concentrations, appropriate respiratory protection must be used.
Personal protective equipment
- Eye protection: Wear safety goggles to protect against splashes.
- Hand protection:
- Use chemical-resistant protective gloves compliant with EN 374.
- Recommended materials for short-term contact (splash protection): nitrile rubber or neoprene.
- Material thickness: > 0.4 mm.
- Breakthrough time: > 480 minutes.
- Check suitability of the gloves for the specific workplace (mechanical resistance, product compatibility, antistatic properties).
- Replace gloves immediately if damaged or worn.
- Preventive skin protection (protective cream) and washing of contaminated skin are recommended.
- Skin and body protection: Wear antistatic clothing made of natural fiber or heat-resistant synthetic fiber. Wash all exposed body parts after contact.
- Respiratory protection:
- If exposure may exceed limit values, use appropriate certified respirators, such as a half-mask with filter cartridge or air-fed respirator.
- Dry sanding, torch cutting or welding on coated surfaces can generate hazardous dust or vapors; where practicable, use wet methods and install exhaust hoods.
- Inside spray booths, operators may need compressed air-fed respirators during spraying until particulate and solvent vapor levels are below exposure limits.
- General protective measures:
- Do not eat, drink or smoke during work.
- Avoid contact with skin, eyes and clothing.
- Keep away from ignition sources and ensure good ventilation in application areas.
