Installation anchor-rim This is one of the first things that an inflatable boat owner thinks about after buying: the regular mounts are often absent or inconveniently located, which makes you look for ways to install yourself, properly installed element ensures safety when anchoring and allows you to feel confident on the water even in windy weather.
The gluing process requires precision and temperature, because the integrity of the entire vessel depends on the quality of the connection. An error in the preparation stage can lead to the part being torn off under load, which at best will result in the loss of the anchor, and at worst - damage to the cylinder. In this article, we will analyze all the nuances so that you can get the job done efficiently the first time.
Selection of installation site and preparation of tools
Before starting work, you need to determine where exactly will be located. anchorIt is most often mounted on the bow of a boat in the center of the keel or on the transom, if you plan to install the engine and the need to fix the vessel with the stern. It is important to consider the geometry of the balloon: the site must be flat, without folds and seams, to ensure maximum adhesion area of the adhesive to the surface.
You'll need the minimum toolkit that any home craftsman can have to work with, and the basic tool requirement is cleanness and no sharp edges that can damage the fabric, and you'll also need to have a workplace that's well lit and protected from dust, which is the enemy of all gluing.
- 🛠️ Toolkit: hair dryer (construction or household), roller (rubber or metal), degreasing (acetone or alcohol), scissors.
- 📏 Marking materials: marker, ruler or flexible roulette for precise positioning.
- 🧴 Consumers: sandpaper (grain content 100-150), rags without pile, gloves for hand protection.
⚠️ Note: Do not use oil-based permanent markers for marking, as they are difficult to remove from PVC and can worsen adhesion of the adhesive.
Careful. surface This is 80 percent of the success of the whole operation, and if you ignore this step, even the most expensive glue will not be able to create a monolithic bond, and the material of the boat is often coated with a protective layer or factory lubricant, which must be completely removed.
Selection of adhesive for PVC
The choice of adhesive is critical, as not all compounds are suitable for polyvinyl chloride. PVC boats use special two-component polyurethane adhesives that become elastic after polymerization and do not crack when the cylinder deforms. Single-component variants are often inferior in strength and resistance to water.
There are various brands on the market that specialize in repair and tuning of inflatable products. When choosing, pay attention to the purpose: the glue should be designed specifically for the purpose of the product. PVC materials And they can withstand constant contact with water, and cheap plastics or rubbers may not provide the reliability that you need.
| Type of glue | Basis | Seizure time | Features |
|---|---|---|---|
| Two-pronged | Polyurethane | 24-48 hours | High strength, elasticity, water resistance |
| single-component | Polyurethane | 12:24 hours. | Easy to use, but less durable |
| Contact | Neoprene/Chloroprene | 1-3 hours | Requires precise alignment, less elastic |
When working with two-component formulations, it is important to accurately observe the proportions of mixing the base and hardener. A violation of the mixture preparation technology can lead to the fact that the glue does not freeze at all or loses its value. strength-plateAlways read the instructions on the packaging of a particular manufacturer.
If you glue the rum at a low temperature, use a special activator or heat the gluing site, as the cold slows down the polymerization reaction.
Technology of preparation of the surface of the balloon
The preparation process begins with a thorough cleaning of the selected place. Use the rags dipped in the degreaser to remove dirt, fat and factory lubricant. Movements should be directed from the center to the edges so as not to smear the contamination on the clean surface.
The next step is machining, and you need to remove the top glossy layer of PVC to open the pores of the material to allow better glue penetration, and you need to use fine-grained sandpaper, and you need to move lightly so that you don't damage the cords of the fabric, but you need to move it intense enough to make the surface matte.
After grinding, wipe the installation site again with a degreaser. Don't touch the prepared surface with your hands, as the skin fat can spoil the adhesion. If it's been a long time between grinding and applying the glue, the degreasing procedure should be repeated immediately before gluing.
Step-by-step instructions for gluing the fry
Now, to the main step, mix the glue components in the proportions specified by the manufacturer, and mix thoroughly to a homogeneous mass. Apply a thin, uniform layer of glue on the prepared place on the cylinder and on the return part of the pit itself (platform).
Let the first layer dry for the time specified in the instructions (usually 10-20 minutes), to the state of "stick". Then apply the second layer of glue on both surfaces. After drying the second layer (when the glue stops sticking to the fingers), you can start to join.
☑️ Checklist of installation
Combine the rum with the marked space on the boat. Starting from the center, carefully roll the part with a roller, driving air bubbles from under the site. The pressure should be uniform and strong enough to ensure close contact of the layers.
⚠️ Warning: Do not try to move the crumbs after contacting surfaces. The adhesive is grasped instantly, and re-adhesive will not be possible without completely removing the part and re-preparing the surface.
Once the load or roll is installed, you have to leave the boat to fully polymerize the adhesive, which usually takes 24 to 48 hours at room temperature, and early operation can disrupt the structure of the adhesive seam, which has not yet gained final strength.
Strengthening of the attachment site (optional)
To improve reliability, especially if the boat will be used on large bodies of water or with a powerful engine, it is recommended to strengthen the installation site of the river. To do this, an additional plate of PVC fabric (pig) with a diameter of 2-3 cm larger than the base of the river is cut.
The piglet is first glued to the tank, and the scum is mounted on it, and this design spreads the load over a large area of fabric, reducing the risk of tearing off when the anchor shaft is jerked, which is especially true for boats made of thin PVC.
Do I need to warm the gluing site?
Warming up to 50-60 degrees before rolling activates the glue and improves penetrative capacity, but requires caution not to overheat and deform the fabric.
Use of use platform It also allows the surface to be leveled if the fry is mounted on a rounded part of the balloon, in which case the platform may be wedge-shaped, providing a vertical position of the fry relative to the water.
Typical errors and ways to fix them
One of the most common mistakes is not cleaning the surface properly, and even microscopic particles of dust or grease can become the center of detachment, and if you notice that the edges of the redhead have started to recede after a while, the problem is probably the preparation.
Another common mistake is to apply a layer of glue that is too thick, and the glue should work as a binder, not as a filler of voids, and the thick layer may not dry out, leaving it sticky and losing strength, and follow the instructions and apply thin layers.
- ❌ Ignoring the drying time between layers leads to the formation of bubbles.
- ❌ Try to glue the poop in the cold or in damp weather without heating.
- ❌ Use of inappropriate solvents that can corrosive PVC.
If you do, don't just try to smear the glue on top, you need to remove the old adhesive completely mechanically (by carefully cutting or cleaning), re-skin and degrease the surface, and then repeat the gluing procedure.
The quality of gluing directly depends on the purity of the surface and compliance with the drying time of each layer of glue.
Care and safety checks for anchorages
After installing the river, it is recommended to check its condition regularly. Before each season, inspect the perimeter of the glue for detachment or bloating. Timely detection of the defect will eliminate it quickly and without consequences.
When washing a boat, avoid using aggressive chemicals at the gluing site. Although modern polyurethane glue is resistant to water and many substances, constant contact with strong solvents can gradually destroy the compound. Use soft detergents and water.
⚠️ Warning: Do not use the installed rum to tow a boat or lift it out of the water. Anchor rum is designed solely for anchoring and is not designed to weigh the entire crewed boat.
Proper maintenance and careful operation will prolong the life of your tuning. Remember that safety on the water depends on small things, and reliable anchoring is one of such important details.
Can I put a squirrel on a wet boat?
Absolutely not. The surface must be completely dry, moisture prevents adhesion of the glue and will cause the part to be instantly removed, and the boat must be dried before work begins.
How much weight can a glued rum bear?
Highly glued rum on a reinforced platform can withstand loads of up to 50-70 kg per tear, which is enough to anchor an inflatable boat. However, the load should be directed along the axis of the rim, not at the kink.
Do I need to remove the old rum before installing a new one?
If the old rum is installed safely and does not interfere, the new one can be glued next to it, but if you plan to replace it, the old one must be carefully removed, cleaned up and re-painted using standard technology.
At what temperature can you glue the rum?
The optimum temperature for gluing PVC is between +15 and +25 degrees Celsius. At lower temperatures, the polymerization process slows down, and the dryer gluing site needs to be heated.
