The owners of the inflatable watercraft know that polyvinyl chlorideThe slabs and bottoms are made of, and despite the high density of modern fabrics, sharp stones, branches and even prolonged exposure to UV light can significantly reduce the life of your vessel. PVC-film It is not just an accessory, but a necessity for those who appreciate the durability of their property.
The use of protective materials allows you to solve several problems at once: from the banal improvement of appearance to the creation of a serious barrier against abrasion. vinyl It takes the first hit, keeping the core tissue intact, and in this article, we'll look at what types of coatings exist, how to properly prepare the surface, and whether it's worth the time to self-paint.
The market offers a variety of options, and it's easy for a beginner to get confused about acronyms and specifications. Some materials are designed solely for decor, while others have a reinforcing structure. Understanding these differences will help you save money and avoid mistakes that can lead to detachment of the coating at the most inopportune time.
Types of protective materials for PVC
The choice of material depends on which part of the boat you plan to protect and what effect you want to achieve. polyurethaneIt's very elastic, and it's very capable of tightening small scratches when exposed to heat.
For those looking for a budget solution, medium-density vinyl options are great at protecting against the sun, preventing color burnout, but inferior to polyurethane in resisting mechanical damage. self-adhesive with reinforced adhesive layer, designed specifically for high humidity conditions.
It is important to consider the thickness of the material, which usually varies from 100 to 200 microns. Thinner options are easier to glue, especially on complex curvilinear surfaces, but their protective properties are lower. Thick coatings require a professional approach and use a building hair dryer for high-quality stacking.
What is the difference between PU and PVC films?
Polyurethane (PU) is significantly more expensive, but lasts 3-4 times longer than vinyl (PVC). PU does not turn yellow over time and is better stretched, returning the shape, whereas vinyl can shrink and crack after several seasons of active use.
Advantages of using protective coating
The main argument in favor of installing protection is the extension of the resource fly-boatMechanical damage, such as punctures and cuts, often occurs in areas of friction against the ground or the side of the pier. The armored film takes that blow, and even if it is damaged, the main cylinder will remain intact.
In addition to physical protection, we must not forget about UV filtersSolar radiation is a hidden enemy of PVC, making the material brittle and brittle over time, and reflects a significant portion of the radiation, keeping the fabric elastic for years to come.
- 🛡️ Antigravel effect Protection against blows with small pebbles and sand at high speed.
- ☀️ Ultraviolet stability - prevention of fading and degradation of the PVC structure.
- 💧 Hydrophobicity Water and dirt stick less to the smooth surface of the film, simplifying washing.
- 🎨 Customization The ability to change the color of the boat or to apply camouflage without painting.
Another important aspect is liquidity: a boat in perfect condition, without scuffs and burnt stains, will cost much more on the secondary market, buyers are more likely to prefer boats that look new visually, and protective coating is the best way to maintain this appearance.
When choosing the color of the film for camouflage, keep in mind that matte surfaces shine less in the sun and do not scare away fish, unlike glossy counterparts.
Preparation of the surface before the sticker
The quality of surface preparation determines 90% of the success of the entire operation. flap It will not be kept on a greasy, dusty or wet basis, and the first step should always be to thoroughly wash the boat using specialized silicone-free detergents.
After washing and drying completely, you need to degreasing. isopropyl Or special degreases for PVC. It is important to wipe the surface with a lilac-free wipe so that the microfibers of the fabric do not remain on the sticky layer.
Particular attention should be paid to the places with the factory sealant If the surface has obvious irregularities or residues of old glue, they must be carefully removed or sanded with fine sandpaper, and smooth transition is critical to prevent bubbles.
☑️ Preparation for pasting
Indoor temperature also plays a role, with temperatures between +18 and +25 degrees Celsius being considered optimal, air that is too cold will slow the glue's reaction, and too hot can cause too fast accretion, which will prevent the material from adjusting its position.
Technology of film application DIY
The pasting process requires patience and a set of tools, and you'll need: a temperature-adjusted building hair dryer, rubber racks of varying stiffness, a stationery knife with a margin of blades, and of course, the very same. shield-filmIt is better to work together, especially if the large planes of cylinders are pasted.
You start by cutting the material, leaving the edges about 2-3 centimeters, which will be cut later, applying the material to the surface, carefully remove the protective layer and, starting from the center, smooth the film with a rakel, driving the air to the edges.
The use of a hair dryer is necessary when bending corners and complex transitions. Heat treatment It makes the material elastic, allowing it to stretch and tightly fit the shape of the boat, but beware: overheating can cause the adhesive layer to deform or damage.
| Tool. | Appointment | Features of use |
|---|---|---|
| Construction hair dryer | Warming and stretching | Temperature not exceeding 150°C |
| raquel | Smoothing | Use the soft edge |
| Knife | Cutting. | Change the blade every 15 minutes |
| ALCOURT | Degreasing | Only pure isopropyl |
Once pasted, it is recommended that the boat be allowed to stand for a minimum of 24-48 hours before first operating or pumping, which is the time required for complete polymerization of the adhesive and maximum adhesion.
Caring and maintenance of an armored boat
Having a protective layer doesn't mean you can forget about the boat; on the contrary, the right care will prolong the life of the surface itself, and regular washing with fresh water after every fishing or walk will help wash away the salt, sand and aggressive river chemistry that can accumulate in the micropores.
To clean the surface, use soft sponges and neutral detergents. Abrasive brushes Aggressive chemicals based on solvents are strictly prohibited, as they can damage the top lacquer layer of the film, making it matte or sticky.
Keep the boat clean and dry, and if you leave the boat inflated for a long time, try to keep it in the shade. UV protectionConstant direct exposure to the scorching sun for months can accelerate aging of the adhesive composition.
⚠️ Attention: Never use gasoline, acetone or chlorine-containing products to clean the polyurethane, which can instantly break down the structure of the polyurethane and dissolve the adhesive, causing permanent damage to the coating.
Periodically check the edges and joints. If you notice that the detachment is beginning, don't wait for water and dirt to fall under the film. Carefully warm the problem area with a hairdryer and press it with a roller. In case of serious damage, local replacement of the site is possible.
Frequent mistakes in self-cleaning
Self-booking is a creative process, but newcomers often step on the same rake. One of the most common mistakes is trying to paste a boat outside in windy weather. Dust and small debris stuck under film can't be removed without removing the entire canvas.
Another mistake is saving on the tool, and using hard scrapers or knives with blunted blades causes scratches on the material itself. Stationary knife It should be sharp like a scalpel to cut the film without damaging the underlying PVC tissue.
Underestimating drying times is also common, with many owners pumping the boat to working pressure immediately after the sticker is put in order to "check" the result, which cannot be done: the glue must stand in place in a calm state, otherwise air pockets will form.
The secret to success is to take your time, and it's better to spend two days preparing and pasting than to redo the work a week later because of bubbles and detachments.
Sometimes you get the wrong choice of material for specific areas, like pasting the bottom with too thin decorative film, the bottom is under maximum load, and you only need thick material. polyurethaneOtherwise, the defense will be wiped out in one season.
Can I put a film on an old, worn boat?
Yes, you can, but only after careful preparation, all the deep scratches and chips need to be ground and maybe primed with a special PVC primer. If the surface is uneven, the film will repeat all the defects, and they will be visible even more.
How long does the glue dry after the sticker?
Primary grip occurs in 1-2 hours, but full polymerization and maximum strength set of adhesive seam take from 24 to 72 hours depending on the ambient temperature and thickness of the film.
Do I need to take film for the winter?
No, you don't have to take film for the winter, and quality materials are designed to be used year-round and can tolerate temperature changes, and film removal is a complex process that can damage the top layer of PVC of a boat.
Does the film affect the boat manufacturer's warranty?
Formally, third-party coatings can be considered as interference with the design, but if the film is applied carefully and does not hide production defects, there is usually no problem.
What is the life of the armored film?
The average life of a quality polyurethane coating is 5-7 years of active use. Vinyl films last less, usually 2-3 years, after which they may require replacement due to loss of elasticity or color burnout.
