Operating an inflatable vessel requires not only proper assembly and storage, but also periodic treatment with special compounds that prolong the life of the material. Many owners wonder how to process the PVC boat so that it lasts longer, does not slide underfoot and maintains an aesthetic appearance. Polyvinyl chloride, from which the balloon fabric is made, is resistant to aggressive environments, but is vulnerable to mechanical damage, ultraviolet and algae foulcing.
The modern chemical industry offers a wide range of solutions, from simple cleaners to complex two-component coatings that change the physical properties of the surface. Competent care It starts with understanding the structure of the material and the processing purposes, and in this article, we'll go into detail about what tools to use to produce the effect, how to restore the faded color, and how to protect the seams from drying out.
Incorrectly selected chemistry can turn a solid boat into a sieve, so it is important to distinguish between PVC products and universal solvents. Textile coatings Polyurethane or acrylic is often confused with specialized plastic varnishes, which leads to unfortunate results. Let's see what really works in the field.
Antifriction coatings: combating slippage
The main problem with any inflatable boat is slippery surfaces, especially when they are wet. To slip on a balloon when you go ashore or cross the side, you get injured or damage equipment. covering Anti-slip, which creates a rough texture, and the most popular aerosol sprays are rubber-based or acrylic resins with abrasive microparticles.
The application process requires careful preparation: the surface should be absolutely clean and fat-free. Alcoholic solutions Or special degreases will remove all traces of dirt, oils and silicone lubricants, and after drying the degreaser, the base layer is applied, and then the main composition, and it is important to follow the temperature regime specified by the manufacturer, usually in the range from +15 to +25 degrees Celsius.
⚠️ Warning: Never apply coatings to wet fabric or high humidity – this will lead to film detachment and bubbles after a few days of operation.
There are also liquid rubbers that, after polymerization, form an elastic, non-slip membrane, which are more durable than sprays, but take longer to apply and dry. Liquid rubber It's great at filling in microcracks and hiding small tissue defects while protecting tissue, but it's worth remembering that removing this coating in the future will require the use of aggressive solvents.
Protection against ultraviolet and aging material
Sunlight is the invisible but ruthless enemy of polyvinyl chloride. UV radiation The plasticizers that make up the tissue gradually evaporate, making the material tough and brittle, a phenomenon called polymer destruction. For this process, you need to use UV filters, and they create a transparent barrier that reflects or absorbs harmful rays.
Regular treatment with protective polyroles not only maintains elasticity, but also makes it easier to clean dirt, and a smooth, treated surface is less susceptible to fouling with mud and algae. Silicone emulsions They are often used to give shine, but they are quickly washed away by water. For long-term protection, it is better to choose fluoropolymer-based formulations or specialized sprays for marine applications.
And you have to pay special attention to the folding and seams, and that's where the material is most tense, and that's where the microcracks are most common, and the treatment of these areas should be more thorough. Specialized air conditioners for PVCThey penetrate the tissue structure, restoring lost plasticizers.
Keep the boat in the shade or in a case, and even the best chemistry will not protect the material if the boat is standing for months in the scorching sun on the shore.
Restoring the color and painting of the boat
And over time, the bright boat fades, and it fades and it's not really presentable. So the question is, how do you paint the PVC boat so it doesn't get cracked? Ordinary paints don't work here, they don't have the elasticity that they need, and they just fall off when you first deflate the balloon. PVC paint polyurethane or acrylic-based.
The painting technology requires strict adherence to the steps: first, the surface is matted with fine sandpaper (P400-P600 grain) to improve adhesion, then a primer is applied, which creates a chemical bond between the plastic and the paint, and only after the primer is completely dry can the primary color be applied. Aerosol paints It is more convenient for small areas, and for complete repainting it is better to use a spray gun.
| Type of coating | Resistance to abrasion | Elasticity | Difficulty of application |
|---|---|---|---|
| Acrylic spray | Low. | Medium | Low. |
| Polyurethane enamel | High. | High. | Medium |
| Liquid rubber | Medium | Very high. | High. |
| Two-component lacquer | Very high. | Low. | High. |
When choosing a color, consider that dark colors (black, dark blue) are heated in the sun much more than light colors, which can lead to increased pressure inside the cylinders and the risk of rupturing the seams in hot weather. Light shades They are more practical in terms of thermoregulation, but they get dirty faster.
Can I paint a boat with ordinary car paint?
Car enamels are not designed for flexible surfaces. When blowing and inflating a boat, this paint will cover a grid of cracks and begin to crumble. Use only specialized compounds marked "PVC" or "Flex".
Cleaning and removing complex contaminants
The question of how to wash a PVC boat of fuel oil, sludge or rust is relevant for every angler. Aggressive chemicals such as acetone, gasoline or chlorine products can dissolve the top protective layer of fabric or disrupt the adhesive seams. So the choice of cleaning agent should be weighted. For most contaminants, warm enough water with the addition of a soft detergent.
Complex spots, such as traces of fuel or oil, require the use of special PVC cleanersThey work gently, breaking down the contaminants, but not damaging the polymer matrix. If you don't have a special tool at hand, you can use a white spirit, but the test on the inconspicuous area is mandatory. Friction should be done with a soft sponge, avoiding abrasive brushes.
- 🌿 Tina and algae: They are easily removed with water under pressure and a soft brush, and antifouling sprays can be used for prevention.
- ⛽ Mazut and fuel: require the use of special degreasing agents or white spirits followed by washing with soap solution.
- 🍂 Organic stains: juice of berries, the leaves are better removed immediately until they have become ingrained in the structure of the material.
After any chemical cleaning, the boat must be thoroughly washed with clean water, and the residue of chemicals on the surface can react with sunlight or begin to erode the material during prolonged storage. Suit before packaging is a critical step to prevent the appearance of mold.
⚠️ It is strictly forbidden to use chlorine-containing bleach (type "White") for cleaning colored boats - they destroy the pigment and weaken the fabric base.
Seam sealing and repair of damage
Sooner or later, repairs are needed. How do you seal or treat the seams so that they don't leak? Special liquid compounds, often called "liquid seams," are dissolved PVC or polyurethane, which, when dried, becomes part of the tissue. Sealants silicone-based for these purposes are not suitable, as they do not have adhesion to PVC.
The process of repairing the damaged area is as follows: cleaned, degreased and covered with glue or liquid PVC. If it is a crack, the edges should be slightly diluted and filled with a composition. To enhance the effect, you can use a reinforcement tape of the same material as the boat. Polyurethane adhesives provide a more elastic compound than PVC adhesives, but require stricter application technology.
☑️ Puncture repair algorithm
Even the most expensive glue will not keep on a dirty or greasy surface, and it is also worth considering the exposure time of the glue before gluing - it varies depending on the air temperature and type of glue.
Seasonal conservation and storage preparation
The end of the season is the time to do the general treatment. How do you treat a PVC boat for the winter so it's new in the spring? First of all, the boat needs to be thoroughly washed, dried and preservatively treated. Many people use glycerol or special spray preservatives that create a protective film that prevents the material from drying out in the dry winter air.
Store the boat should be in a straightened or half-blown state, away from heating devices and direct sunlight. Temperature conditions Storage is important: -20 to 30 degrees is optimal, but sudden changes are undesirable. The packaging bag must be so that moisture does not accumulate inside.
Before the first inflatation after winter, the boat should not be pumped immediately to working pressure. Let it lie in a warm room for several hours, then pump and leave for a day to check the tightness of the seams. Smooth recovery The material will extend its life.
The main secret of the longevity of PVC boats is not so much chemistry as proper drying before packaging and storage away from direct sunlight.
Frequently Asked Questions (FAQ)
Can I paint a PVC boat with ordinary spray paint?
No, the regular paint doesn't have the elasticity it needs, it'll crack and fly around when blown and inflated, and only use specialty paints labeled "PVC" or "Flexible."
How often should the boat be handled?
The frequency depends on the intensity of the operation, and the average fishing season is one season, and it is recommended to update it before the start of each season if you feel that the surface has become too slippery.
How to wash the boat from fuel oil, if there are no special means?
You can try using white spirit or kerosene, but you need to act quickly and carefully, immediately washing off the residues with soap solution.
Do I need to lubricate the seams of the boat before storage?
You don't have to lubricate the seams with thick lubricants, you have to have a clean, dry and clean surface, and if the seams look dry and whitish, you can wipe them with a special PVC conditioner, but not with oil or solidol.
Is PVC afraid of frost?
At temperatures below -20°C, PVC becomes brittle; in the cold, the boat is easily damaged mechanically (by a blow or a bend); it is not recommended to inflate and actively use the boat in severe frost.
