When the water suddenly squashes under your feet, boat-flood It turns a walk into a battle for the survival of a vessel, which is familiar to many aquatic motorists. It's not just a discomfort in the form of wet feet, it's a signal of a critical leakage. bottom-layer It can cause serious consequences, including loss of buoyancy in open water, if you ignore the first signs of leakage.
Moisture accumulating between balloon hard or soft bottomIt creates the perfect environment for mold and decay, especially if the floor is made of plywood. Prolonged exposure to water in a confined space accelerates the deformation of materials and reduces their strength specifications. Understanding the nature of the origin of the floodplain is the first step to saving your life. boat from premature aging.
In this article, we will look at all possible causes of moisture, from banal condensation to complex tissue tears, and consider proven methods for eliminating defects. A competent approach to diagnosis will allow you to avoid expensive repairs in the workshop and prolong the life of the boat.
Mechanism of moisture formation and main causes
Before you grab the glue, you need to clearly identify the source of moisture. boat-flood It's not because of a hole in the balloon, but because of a combination of less obvious factors, and it can come from outside through microcracks, or it can form inside a closed volume because of temperature differences.
One of the main reasons is a violation of tightness gluedThey connect paioles (hard floor) to cylinders, and when you're in active use and temperature changes, the glue loses its elasticity, and there are microgaps, and through them, the water that's taken up by the spray is drawn under the balloon by the effect. Venturi when moving.
It's also natural. Condensate is produced when warm, moist air meets cold surfaces of PVC or water, and this is especially true in the morning or when the weather changes abruptly. If you find that the water is rust colored or smells bad, it's rotting. plywoodA man who's been soaking up moisture for years.
- 💧 Violation of the tightness of the adhesive seam along the perimeter of the bottom
- 🌡️ Condensation formation due to the change in air and water temperatures
- 🪵 Rotting of plywood floorboard absorbed moisture
- 🕳️ Mechanical puncture or rubbing of the cylinder tissue in the contact zone with the ground
⚠️ Warning: If the water in the boat has an oily film or a specific fuel odor, check immediately.
lower unitAnd the mounting points of the slab, and maybe the problem is not the floor, but the engine installation system.
Diagnosis: Where exactly does it flow?
Finding the source of the leak requires methodical approach and patience. It is not enough to just draw out the water, you need to find the entry point. PVC You need to completely drain, thoroughly wipe all surfaces and leave to dry in a warm room for at least 24 hours.
After drying, inflate the cylinders to working pressure and leave the boat for a few hours. If the pressure has dropped and the external holes are not visible, use a soap solution. Pour the foam profusely on the joints of the cylinder with the bottom and seams. Even small bubbles will indicate where the air is poisoning and, therefore, water can pass.
Pay special attention to the state plywoodTake them out of the boat and look at the ends, and if the plywood has become stratified, blackened, or soft, it no longer acts as a barrier, and it becomes a source of moisture itself, giving the accumulated water back into the space under the cylinders with each heat in the sun.
To test the integrity of the fabric in hard-to-reach areas, you can use the tinted water method. Carefully pour dye water on the joints outside, watching the inside. This method requires an assistant and good lighting, but gives 100% results when looking for microcracks in the interior. glued.
Repair of glue seams and elimination of leaks
Re-sealing is a process that requires compliance with temperature and technology. PVC fabric And we use special two-component polyurethane adhesives, and a regular "moment" or universal adhesives won't work, because they don't have the necessary elasticity and water resistance.
Before work begins, the surface must be cleaned with fine sandpaper (granularity 200-400) to create roughness, then degrease the surface with a special composition or acetone, strictly following the instructions for the glue. The application of the glue is usually done in two layers: the first layer is absorbed into the structure of the material, the second creates an adhesive film.
Sticking a patch or reconnecting a seam requires a strong press. Use a roller to drive all the air bubbles out of the glue. It is important to ensure uniform pressure throughout the glue area. The time for complete glue polymerization is 24 to 72 hours, depending on air temperature and humidity.
☑️ Preparation for seam repair
If the damage is in a difficult place, for example, timber or in the area of the stringer, it may be necessary to partially paste the element, in such cases it is better not to save time and contact professionals, as improper assembly can disrupt the geometry. boat.
The problem of floor rotting and replacement of floorboards
The most insidious reason why it appears boat-flood The moisture that gets under the cylinders often stays there forever if there are no drainage holes or they are clogged, and the plywood used in floorboards, even moisture-resistant (FSF), loses its properties over time.
When the wooden flooring starts to rot, it turns into a sponge, and when it parks, it absorbs water, and then it starts to sweat in the sun, releasing moisture back as steam, which condenses on cold PVC. Visually, it looks like constant dampness, although there may not be holes in the cylinders.
The solution is radical: completely replacing decks, and modern technology allows us to make new paioles from composite materials or aluminum that are absolutely not afraid of water, and if you decide to leave the plywood, be sure to treat the ends and surfaces with epoxy resin or special impregnations.
| floorboard material | Weight (kg/m2) | Moisture resistance | Term of service |
|---|---|---|---|
| Plywood FSF (9 mm) | ~6.5 | Medium (requires processing) | 3-5 years |
| Aluminum (2 mm) | ~5.4 | Tall (not rotting) | 15+ years |
| Composite (Plastic glass) | ~4.0 | Absolute. | 10+ years |
⚠️ Warning: Never dry a wet plywood floor in direct sunlight or near the battery. Rapid drying will cause deformation and cracks, after which the water will flow even more actively.
Prevention: How to prevent the appearance of water
Preventing moisture is easier than dealing with the consequences. Regular maintenance PVC This involves not only washing, but also checking the drainage valves, making sure they are not clogged with sand or grass and letting water out.
Boat storage is also critical, and if you leave the boat assembled, be sure to raise your nose and stern to allow water to flow out of the cylinders, and the ideal option is to store it in a disassembled, dry room where condensation is not allowed.
Use paiola mats, which not only improve comfort, but also create an additional barrier to protect the underside fabric from abrasion and spread the load. Small pebbles that fall between the bottom of the boat and the paiola can eventually wipe out. PVC fabric to the holes.
Should I make drainage holes in the floorboard?
Many craftsmen recommend drilling small holes in the corners of plywood peyols to drain water, but this is a controversial point: on the one hand, water leaves, on the other, water can be sucked into the boat through these holes when moving, it is better to ensure the perimeter is tight than to leak the floor.
Selection of materials for quality repair
The quality of the repair depends on the materials used, and the market offers many options, but for the purpose of the repair, the product is not very expensive. PVC Only specialized formulations are suitable. Cheap analogues can give a temporary effect, but under the load and exposure to ultraviolet light, they quickly collapse.
When choosing adhesive, consider whether it's for PVC or rubber. It's different chemical bases. It's also important to have the type of compound: hot gluing (with a hairdryer) is stronger than cold gluing, but requires skill. For home repairs, cold gluing is most often used with two-component polyurethane adhesives.
The patch fabric must be identical to the boat material or have similar elasticity specifications. Using a stiffer fabric on a soft cylinder will detach the edges of the patch. Always leave a supply of material for future repairs when buying a boat.
When buying a remake, immediately purchase a special degreasing agent and roller. The use of improvised means (gasoline, a bottle instead of a roller) often leads to a marriage of gluing.
Frequent mistakes in eliminating floods
The most common mistake is to try to seal the hole without draining or degreasing the surface, and the glue will not lie on a wet or greasy base, and in a week the water will reappear in the boat, and careful surface preparation is 80% of the success of the repair.
Another mistake is to use too large patches "just in case," bulky designs disrupt the aerodynamics and flexibility of the balloon, creating new points of tension of the fabric, the patch should cover the damage with a margin of 3-5 cm, but no more.
Ignoring the time of drying glue is a way to re-repair, many people rush to lower the boat or pump it immediately after gluing, polymerization is a chemical process that can not be accelerated by heating the dryer (unless it is provided by technology), violation of time regimes makes the seam weak.
A high-quality repair of the floodplain is impossible without drying the boat completely and observing the time of glue exposure, and haste here is the main enemy of tightness.
Can I seal a hole on a wet boat?
Absolutely not. Water blocks adhesion of the adhesive. Even special adhesives require dry surfaces for initial grasping. Attempting to repair on a wet surface will only result in a loss of material and time.
How often should I check the boat for a flood?
Visual and pressure checks are recommended after every active fishing or walk, and deep soap solution diagnosis should be done at the beginning and end of the navigation season.
Will talc help in the fight against condensation?
Some boat owners sprinkle talc under the cylinders to soak up moisture, a temporary measure that may alleviate the situation, but will not solve the problem of rotten floor or leaky seam.
