Installing an additional anchor ditch is one of the most frequent and useful improvements that inflatable boat owners perform. Standard equipment often involves only one ditch on the nose, which is not always convenient when fishing or maneuvering in windy weather. An additional anchor point allows you to change the angle of drift, fix the anchor tile from the stern or create reliable insurance when landing.
The adhesive process anchor-rim It doesn't require complex tools or professional equipment, but it's critically dependent on compliance. A mistake in surface preparation or the wrong choice of glue can cause the element to fall off at the wrong time, leaving the boat without anchor. In this article, we'll look at all the nuances of working with PVC materials.
The challenge is to create an inseparable chemical bond between the metal or plastic of the rosy and the polyvinyl chloride fabric of the side, and it's not enough to just smear the glue and press the parts, it's necessary to activate the surface of the material so that the glue molecules penetrate the structure of the PVC, and this activation process is key to the longevity of the compound.
Choosing the Right Adhesive for PVC Materials
The success of the whole operation depends on 90 percent of what you glue, and the market offers many options, but not all of them are suitable for creating power joints that are constantly under stress and in contact with water, and using the wrong compound will cause the rum to unstuck after a few weeks or even during the first fishing.
The most reliable option is considered polyurethaneThey're made up of a base and a hardener that are mixed just before use. Klejcoll or Texacol They're using a hardener to create a seam that is often stronger than the material of the boat, and they're not afraid of salt water, ultraviolet light, and temperature changes.
If you glue the rum for the first time, buy glue with a stock - the finished mixture does not live long, and the residues will be needed for smearing edges or repairs in the future.
Single-component adhesives that are dried by evaporating the solvent are also applicable, but require more careful preparation and are often inferior in elasticity. PVC Glue guns or universal "superglues" are not suitable, because they make the material tough and brittle.
Why is two-component glue better?
In two-component compounds, a chemical polymerization reaction occurs, creating strong bonds between the molecules of the adhesive and the material. Single-component adhesives work by dissolving the surface layer, which gives a less strong compound at high loads.
Necessary tools and workplace preparation
Before you start, you need to prepare all the tools so that the process does not stop looking for details. To properly install the pome, you need not only the glue itself, but also the means for degreasing, cleaning and fixing. The workplace must be dry, warm and well-ventilated.
The optimum temperature for bonding PVC is between +15 and +25 degrees Celsius. At lower temperatures, the polymerization reaction may not go or be sluggish, which will affect the strength of the seam. High humidity is also unacceptable, since moisture can be preserved under the adhesive layer.
List of necessary tools and materials:
- 🛠️ Sandpaper with grain of 100-150 (for surface cleaning)
- 🧪 Solvent (acetone, white spirit or special degreasing)
- 🖌️ Brush for applying glue (usually comes complete or synthetic)
- 🔥 Hair dryer construction (preferably with temperature adjustment)
- 🧱 Load or squeezing rod (if the construction of the squeezing allows)
And the particular thing to pay attention to is the dryer, and warming the surface is not just drying, it's a way to activate the polymer molecules, making it more susceptible to glue, but overheating is dangerous, because if the material starts to melt or bubble, its structure will be irrevocably disrupted.
Preparation of the surface of the boat and the rift
The most important step, which is where errors happen most often, is to prepare the surface to remove all the contaminants, the factory coatings, and create roughness for better adhesion, and even a microscopic film of fat or dust can cause detachment.
First, the installation site is thoroughly cleaned with a solvent, which removes fatty stains, silicone greases and dirt, and then you take sandpaper, and not only the area under the rum, but the sole of the mug, if it's made of plastic or rubberized material, and the metal dips also require stripping at the contact point.
The stripping area should be 1 to 2 centimeters larger than the area of the sticking element, creating a buffer zone where the glue will be placed directly on the cleaned material, and after mechanical stripping, the surface will be degreased again.
The quality of the cleansing and degreasing directly affects the strength of the joint – do not save time at this stage.
Technology of applying glue and gluing
The gluing process requires strict sequence of actions. For two-component adhesives, the base and hardener are first mixed in the proportion specified by the manufacturer (usually 100:4 or 100:10).
The glue is applied in a thin, uniform layer on both the surfaces that are glued together, both on the boat and on the sole of the squirrel. Don't try to thicken it, because the thick layer of glue dries longer and holds worse. After applying the first layer, you need to let it dry to "slip".
The drying time depends on the temperature and the type of glue, which is usually 15 to 30 minutes. The finger should not stick to the glue, but the stickiness should be maintained. If the glue is dry, it should be activated with a warm-up hairdryer. Then a second layer is applied, which is also dried.
The final step is to heat the hair dryer up to 50-60 degrees, and you can check the temperature with the back of your hand, which is hot but bearable, and then you get warm, and then you connect and you press it very tightly, and you have to squeeze all the bubbles out of the smoke.
Table of gluing steps:
| Phase | Action. | Time/Temperature | Preparedness criterion |
|---|---|---|---|
| 1. Sweeping. | Grinding and degreasing | - | Matte surface |
| 2. First layer | Applying glue | 15-20 minutes | Complete drying |
| 3. Second layer | Application and drying | 5-10 minutes | Sticky to the break. |
| Activation | Hair-warming | 50-60°C | Tolerable for the hand. |
| 5. Connection | Pressing and rolling | Right away. | Absence of bubbles |
Fixing and time of polymerization
After joining the parts and removing air (rolling with a roller or finger through the fabric), you need to ensure a tight fit for the entire polymerization period. The glue does not gain final strength instantly. Primary fixation occurs after a few hours, but full strength is achieved after 24-72 hours.
The weight of the cargo depends on the size of the cone, usually 3-5 kg. If the design allows, you can use soft-pad rods, but the load is simpler and safer for the shape of the boat. It is important that the boat at this time lies straightened, without tension of fabric in the place of gluing.
☑️ Checklist before launching
Don't try to test the strength of the joint immediately after the load is removed. Give the glue a rest for another day. Early load can lead to microcracks in the still-hardened seam, which will manifest later under load.
Typical errors and security measures
Failure to comply with technology often leads to unfortunate results, and one of the most common mistakes is sticking together in the cold or on a wet surface, and water that gets between the layers of glue will turn into steam when heated or simply breaks the adhesion, creating a point of detachment.
What happens if you don’t warm up the surface?
Without heating, the glue will remain on the surface without penetrating the PVC structure. Such a connection will only hold due to stickiness, not a chemical bond, and easily break off under load.
Another mistake is using too much hardener, and some craftsmen think that the more hardener, the faster and stronger the glue will grasp, which actually upsets the chemical balance, and the seam becomes brittle and can crumble.
⚠️ Warning: Only work with glue and solvents in a well-ventilated or outdoor environment. Solvent vapors are toxic and flammable. Don't smoke near an open can of glue!
It's also dangerous to overheat the material with a hair dryer. If you see PVC shining more than usual or deforming, stop heating immediately. The overheated material loses its strength and elasticity, becoming vulnerable to rupture.
Care for established scavenging
After successful installation and drying, the rim requires minimal but regular maintenance. Periodically check the condition of the adhesive seam, especially after long-term storage of the boat in a deflated state or after active operation.
Pay attention to the edges of the sticker, and if you notice a gap or dirt in the area, clean the area carefully and smear it with a little glue, which will prevent further detachment.
Regular visual inspection of the places of gluing of additional equipment is the best prevention of loss of anchor or other troubles on the water.
When washing a boat, try not to pour a powerful jet of water under high pressure directly into the junction of metal and rubber, so as not to wash out the adhesive layer. Observing these simple rules will allow the additional smear to serve you faithfully for many years.
Can I put the squirrel on a wet or wet boat?
Absolutely not. Moisture is the main enemy of bonding. Even microscopic drops of water will not allow the glue to connect with the material. The boat must be completely dry and warm. If you bring the boat from the cold to the heat, let it warm up and dry for at least 2-3 hours before work begins.
How much dried PVC glue?
The primary polymerization time is about 24 hours at a temperature of +20 ° C. Full strength is gained after 3 days. It is recommended to operate the boat (launch, load) not earlier than 24 hours after gluing.
How to replace a building hair dryer if it is not?
There is no perfect replacement. A household hair dryer doesn't give the right temperature (usually 60-70°C at the exit, but cools down at a long distance), you can try using an iron through several layers of fabric, but it's risky - it's easy to overheat and spoil the boat, it's better to borrow or buy an inexpensive construction hair dryer.
Can I get a winter coat in the garage?
Only if the garage has a temperature above 15°C and low humidity. If the garage is cold (+5...+10°C), the glue may not react or dry for weeks, remaining sticky. Also, you can not glue on the cold material of the boat - bring it to the heat in advance.
What to do if the squirrel is still unstuck?
Don't despair. Pull the residues of old glue mechanically (with a knife or sandpaper), thoroughly clean the surface again, degrease and re-glue, strictly following the technology, often re-adhesive holds even better than the first one, since the surface is already prepared.
