Every owner of the boat sooner or later faces the question of increasing comfort and safety on board. EVA boat cover It has become the standard in modern shipbuilding and tuning, displacing traditional wooden flooring and slippery surfaces from fiberglass, a material that combines lightness, strength and excellent tactile properties.
And this flooring is a huge change in the experience of steering a boat, making it a very safe place to walk on deck, even in wet weather. EVA foam It does not absorb water, is resistant to ultraviolet light and chemical influences, which are critical for marine and river applications, and in this article we will discuss in detail all the nuances of choice, technology of gluing and care of this modern material.
Before you start purchasing materials, you need to clearly understand what surface you will work with. EVA carpet It can be installed on a rigid case of aluminum or fiberglass, and on inflatable tubes of PVC. The versatility of the material allows you to create complex geometric shapes that repeat the curves of the deck, which is impossible to do with the use of rigid plates.
What is EVA Material and Its Key Benefits
Ethylene vinyl acetate is a copolymer of ethylene and vinyl acetate, which, after special foaming treatment, acquires a porous structure. depreciationThis material does not rot, mold and is completely inert to salt water, making it an ideal choice for use in any climatic conditions.
The most important property is thermal insulationStepping on such a floor barefoot, you will not feel the cold from frozen metal or fiberglass, which is especially true in the off-season, and the material has excellent noise-absorbing specifications, reducing the resonance of engine operation or waves hitting the body.
- 🌊 Wet resistance: The material is completely closed-mesh, water does not penetrate into the structure, preventing the development of bacteria.
- ☀️ UV stability: Quality brands of EVA do not burn out and do not lose elasticity under the influence of direct sunlight.
- 🛡️ Chemical inertia: Resistant to gasoline, oil, acids and alkalis, often used on a boat.
⚠️ Caution: Cheap EVAs can contain harmful volatiles. When buying, be sure to require safety certificates, as you will be above this material for a long time.
The life of the coating is between 7 and 10 years of active use, which is comparable to the life of the boat itself, but the visual specifications remain unchanged: the color does not dim, and the texture does not “glaze” to a smooth slippery surface, as is the case with paint.
When choosing a coating color, consider that dark colors (graphite, black) heat up in the sun more than light colors (gray, beige), which can be noticeable when cruising barefoot on a hot day.
Comparison of EVA with PVC and other floor materials
Choice between eva traditional PVC PVC mats, often called puzzles, are cheaper but have a number of significant drawbacks: They are stiffer, they lose color faster and can be layered at joints over time.
EVA material wins in tactile sensation: it is softer and more pleasant to the touch, resembling dense rubber or cork. Compared with plywood covered with carpet, EVA does not swell from moisture and does not require drying after each fishing, which greatly simplifies. operation.
| Characterization | EVA (EVA) | PVC (PVC) | Plywood + carpet |
|---|---|---|---|
| Water absorption | 0% (not absorbing) | Minimum | High (rotting) |
| Tactical comfort | Tall (soft) | Medium (hard) | Low (hard) |
| Term of service | 7-10 years | 3-5 years | 2-4 years |
| Difficulty of installation | Medium (glue) | Low (laying) | Tall (sweeping) |
Another important aspect is security. Anti-slip properties EVAs persist even when there is oil or mucus on the surface, while wet PVC becomes ice-like, a critical safety factor, especially for children or the elderly on board.
Preparation of the surface before the EVA sticker
The quality of the base preparation determines 90% of the success of the entire boat upgrade operation. The surface must be perfectly clean, fat-free and dry. Any residue of old glue, paint or dirt will lead to detachment of the material in the future, which will require complex and complex work. repair.
Start with mechanical cleaning. If there is swelling of old paint or rust on the floor (on aluminum boats), they should be cleaned to metal. For fiberglass cases, it is enough to thoroughly wash the surface using special detergents that remove fat film.
- 🧹 Cleanup: Remove all dust and debris with a vacuum cleaner and a wet cloth.
- 🧪 Degreasing: Use acetone, white spirits or specialized degreasers (for example, Novol 770).
- 💧 Drying: let the surface dry completely, moisture between the glue and the body is unacceptable.
Pay special attention to the corners and joints of the sides with the bottom. This is where dirt and moisture most often accumulate. If you plan to close EVA large areas, it is recommended to pre-expand the sheets on the floor without glue to assess the cutting and cutting.
⚠️ Warning: Do not use aggressive solvents that can damage the structure of fiberglass or dissolve paint on the sides of the boat. Always test the product on an inconspicuous area.
The ambient temperature during preparation and sticker should not be lower than +15 ° C. The cold material becomes rigid and poorly glued, and in conditions of high humidity, the glue may not polymerize properly.
☑️ Preparation for installation
Installation technology: step-by-step instructions
Sticking process EVA coverage It requires precision and quality adhesives, and polyurethane single-component adhesives, such as polyurethane adhesives, are the most proven. 3M 5200, Sikaflex Or special aerosol adhesives for EVA, if the area is small, and for larger areas, it's better to use adhesives applied with a serrated spatula.
Apply the glue uniformly on both surfaces, both the boat floor and the back of the EVA sheet, and let the glue dry for the time specified by the manufacturer (usually 10-20 minutes) to the "stick state." This is an important point: if glued right away, the material can "swim."
Sequence of action:1. Apply the glue on the base.
2. Apply glue on EVA.
3. wait 15 minutes (time depends on temperature).
4. Apply the sheet carefully, starting at one end.
5. Roll the roller from center to edge.
After you dock the sheets, you need to carefully roll the surface with a hard rubber roller, which will remove the air bubbles and ensure maximum contact area of the glue with the surface. If you use sheets with a chamfer (skos of edges), make sure that the pattern and gaps match perfectly.
What to do if the glue is frozen ahead of time?
If the glue is dry and you haven't glued the sheet yet, don't try to apply a new layer on top, you need to remove the solidified glue completely mechanically or with a solvent, degrease the surface again and repeat the process.
For complex areas, such as bends of cans or transitions to the sides, the material can be heated with a building hair dryer. At a temperature of about 60-70 ° C. ethylene vinyl acetate It becomes elastic and easily takes the desired shape, and after cooling, fixes it.
The main secret of high-quality installation is not to rush with the final glue and give the glue to reach the desired degree of stickiness, otherwise the sheets can move when rolling.
EVA care and service life
Despite the high wear resistance, EVA It requires minimal maintenance to maintain its presentable appearance, the main enemy of the material is dirt, which is clogged into the pores of the texture, and regular pressure washing (kercher) allows you to quickly remove sand and silt.
For deep cleaning, use soft brushes and neutral detergents. Aggressive chemistry can change the color or structure of the top layer. If you have persistent oil or fuel stains on the coating, you can remove them with rags dipped in diesel or a special cleaner.
- 🚿 Regular washing: Rinse the floor with fresh water after each exit to salt water.
- 🧼 Deep cleaning: Once a season, wash using a soft brush and soap solution.
- ☀️ Storage: During winter, it is better to keep the boat in the shade or under the awning to minimize the UV load.
The service life is directly dependent on the intensity of operation: on pleasure boats, the coverage lasts for decades, while on professional fishing vessels with constant heavy lifting and aggressive environments, the resource can be reduced to 5-7 years.
⚠️ Warning: Never use metal brushes or scrapers to clean the EVA coating. They will irrevocably damage the texture and the material will wear out and stain faster.
If a segment is damaged (for example, a cut by a sharp object), it can be replaced, carefully cut the damaged piece along the contour of the texture and a new, prepared fragment is pasted in its place. Repair of EVA coating is only possible using a similar material of the same batch to avoid color differences.
Frequently Asked Questions (FAQ)
Can I glue EVA directly onto an old slippery floor without cleaning?
It's not recommended, the adhesion of the adhesive is going to be extremely low, and the coating will quickly move away in stockings, and you need to create roughness (sharp) on the old coating or remove it completely.
How to cut EVA material at home?
For smooth cuts, use a sharp construction knife with interchangeable blades and a metal ruler. For curly carving around hatches or studs, electric blades with a wood file (at minimum speed) or special knives for EVA are best suited.
How safe is EVA coverage for children?
Absolutely safe: Certified material is toxic-free, does not cause allergies and provides excellent cushioning when falling, making it ideal for family boats.
Can I paint the EVA coating?
Normal paints -- no, they don't stick to the surface, but there are special compounds to restore EVA color if the material is burned out, and in most cases, it's easier to replace the burnt out segment than to try to paint it.
