Operating an inflatable craft in difficult conditions often involves the risk of mechanical damage, whether it is a sharp stone, a snag or a shell on the bottom. PVC boat reservation It is not just a desirable procedure, but often a necessary one for those who value the durability of their equipment and do not want to risk expensive repairs in the middle of a reservoir. Many owners still mistakenly believe that factory coverage is sufficient, but practice shows that strengthening the most vulnerable areas significantly prolongs the life of the product.
The process of applying an additional protective layer requires not only the availability of high-quality materials, but also an understanding of the physicochemical processes occurring during the gluing of polyvinyl chloride. PVC boat With well-designed armor, it becomes virtually unsinkable in the everyday sense, withstanding hard contact with abrasive surfaces. In this article, we will discuss how to do this work yourself, avoiding the typical mistakes that beginners make when working with adhesives.
It is important to note right away that saving on materials to protect the bottom is a false saving that can lead to a complete loss of tightness of cylinders. High-quality armor on a PVC boat must withstand not only puncture, but also severe friction against the sand when pulling ashore, maintaining elasticity at negative temperatures. Preparation for work takes no less time than the process of pasting, and ignoring this stage negates all efforts.
Selection of materials for reliable protection of the body
The first step towards an indestructible craft is to choose the right materials, because they are the ones that determine the adhesion and the ultimate strength of the layer. boat-booking Professionals recommend using specialized fabrics based on high-density PVC. Conventional awning material or tarpaulin will not work, as they do not have the necessary elasticity and can detach when the cylinder deforms.
The key element is glue, which should allow the materials to be chemically welded, rather than just gluing their surfaces together. polyvinyl chloride Two-component polyurethane compounds are ideal, which, after polymerization, create a seam that is stronger than the material itself. chloroprene (neoprene) single-component adhesives are also used, but they are less resistant to constant water exposure and temperature changes, which is critical for the bottom.
And don't forget the solvents that are needed to degrease and activate the surface before applying the adhesive. Using aggressive chemicals that aren't designed for PVC can burn the top layer of tissue, making it fragile and vulnerable. Always check the compatibility of the solvent with your boat's material in an inconspicuous area.
⚠️ Warning: Never use Moment glue or other household products to book the bottom, they can't withstand constant contact with water and tear loads, peeling off after 2-3 seasons of active use.
The secrets of glue selection
Which glue to choose for armor?: Two-component polyurethane adhesives (e.g. Wignol, Kleyberg, Tensol) are best suited for reliable protection. They create a chemical bond between PVC molecules, turning two pieces of fabric into a monolith. Single-component adhesives (based on rubber) create an elastic but less durable seam that can be layered over time by moisture and ultraphyet.
Surface preparation and necessary tools
The quality of the surface preparation determines 80% of the success of the entire operation to strengthen the protection of the hull. Before starting work, the boat must be completely lowered, thoroughly washed with detergents and dried, removing all dirt, sand and greasy spots. Any grain of sand left under the layer of armor will become a point of tension around which the material will detach during loads.
To carry out the work, you will need a set of tools that should be at hand so that the process does not interrupt. Booking technology It requires precision and precision, so it's not a rush, and degreasing the surface with acetone or a special activator is a must-see step, even if the boat is visually clean.
After cleaning, it is recommended to slightly go through the place of application of armor with fine sandpaper to improve adhesion, but this should be done extremely carefully so as not to damage the main layer of tissue. Some masters recommend heating the surface with a hairdryer before applying the glue, which helps activate PVC molecules and improve adhesion.
- 🛠️ Tools: Roller for rolling (preferably Teflon or rubber), brushes with hard bristles, building hair dryer, scissors, ruler.
- 🧴 Chemistry: Two-component glue, solvent (acetone, toluene or specialized activator), degreasing agent.
- 🧼 Expenditure: No pile, gloves, paint tape for border markings.
Technology of applying a protective layer on the bottom
The process of applying armor to the bottom of the boat requires compliance with the temperature regime and time intervals specified by the adhesive manufacturer. Usually the adhesive is applied in two layers: the first layer is rubbed into the fabric and dries to a stick (about 15-20 minutes), the second is applied more abundantly and also aged for a certain time. It is important not to overreact the glue, otherwise it will lose its adhesive properties, and do not hurry to keep the solvent inside the seam.
When applying a prepared piece of armor on the bottom, you need to act quickly and accurately, since the activated glue is grasped instantly. PVC boat It should be on a flat surface, and the armor material should be spread out from the center to the edges, driving the air out with a roller, and the movement of the roller should be directed from the center to the periphery, to prevent the formation of air bubbles.
Special attention should be paid to the edges of the protective linings: they should be carefully rolled and, if necessary, additionally smeared with glue around the perimeter. If you use a material with riffling, make sure that the direction of the picture coincides with the direction of movement of the water or just looks aesthetic.
☑️ Checklist of bottom-cleaning
Reinforcement of cylinders and critical areas
Although the bottom takes the brunt of the blow, the cylinders also need protection, especially in the lower part of them, where they come into contact with water and boards upon landing. Reservation of cylinders It is often performed as strips along the keel or in the mounting places of cans and transoms, and these zones are subject to constant friction and can be damaged by equipment or hooks.
To reinforce the transom where the motor is attached, you often use additional thicker material linings or multi-layered pastings, and the vibrations from the running engine create dynamic loads that can lead to microcracks at the intersection of the transom and the cylinder, and the reinforcement of this zone extends the life of the entire structure.
When working with cylinders, it is important not to overdo the thickness of the armor layer, as this can disrupt the geometry of the inflated boat and make it difficult to pack it into a regular bag.
| Protection zone | Recommended thickness | Type of material | Features of installation |
|---|---|---|---|
| Day (fully) | 1.5 - 2.0 mm | PVC 850-900 g/m2 | A full-on slack on board. |
| Bottom of cylinders (Kilson) | 1.0 - 1.5 mm | PVC 650-750 g/m2 | Strips along the side, reinforced joints |
| Tranza | 2.0 - 3.0 mm | PVC reinforced | Multi-layered pasting, cylinder capture |
| Nose part | 1.0 mm | PVC standard | Protection against strikes on the pier |
⚠️ Attention: When pasting corners and transitions from bottom to cylinders, make incisions of the material ("anchors") to avoid creases. The fold is the place where the armor will come off first.
Professional advice: Use paint tape to pre-mark the boundaries of the reservation, which will create a smooth line of tear and carefully decorate the edges of the protective layer.
Drying, polymerization and quality control
Once the mechanical part of the work is complete, the boat takes time to fully polymerize the adhesive, although the adhesive can take hours to grasp. solidity It is recruited within 24-72 hours depending on ambient temperature and humidity. Don't rush to inflate the boat immediately after peeling - this can lead to layer displacement or bubble formation.
The optimal temperature for drying is considered to be a range of +15 to +25 degrees Celsius. Direct sunlight in the first hours of drying is undesirable, as they can cause too rapid evaporation of solvents, which will lead to boiling of the glue and the appearance of pores in the seam.
Before you first fully operate, make a visual inspection and tactile check of all the seams. Run your hand around the edges of the armor, there should be no detachment or bloating. If you find a defect, it must be repaired immediately by gluing the site again.
Take your time to launch the boat immediately after booking. Let the glue gain 100% strength for 3 days at room temperature - this is a guarantee of durability of protection.
Frequently Asked Questions (FAQ)
Can I book a boat in the garage in winter?
Yes, you can, but only if the room temperature is stable above +15 ° C and there is no draft. Low temperature slows down the reaction of the glue polymerization, making the seam weak, and high humidity can lead to clouding of the seam and loss of adhesion. Be sure to warm up the room and the boat before work begins.
How much will the weight of the boat increase after the booking?
Weight will increase by an average of 3-5 kg depending on the area of the sticker and the thickness of the material used. For an inflatable boat, this is a minor additive, which is fully compensated for by increased reliability and no risk of puncture. The balance of the boat on the water will not change much.
Do I need to skin the surface before applying glue?
In most cases, modern two-part adhesives do not require mechanical cleaning if the surface is clean and fat-free. However, if the boat is old and has an oxidized layer, light sanding with fine sandpaper (P240-P400) will improve grip, the main thing is not to damage the reinforcing layer of fabric.
How to remove the reservation if it is damaged?
Removing high-quality armor is a time-consuming process, using a building dryer (heating softens the glue) and special washes for PVC glues, removing the armor carefully so as not to damage the main material of the boat, after removing it will require a complete cleaning of the surface of the glue residue before re-sticking.
Should I book a new boat?
Yes, it makes sense to book a new boat right after you buy it, so you can put protection on a perfectly clean, unwound surface, which will ensure maximum adhesion, and you can also protect the boat from the first scratches that inevitably appear on the first trips.
