How to glue rum to the PVC boat: instructions with photos and expert advice

Installing PVC rims on a boat is a challenge that every boat owner faces sooner or later. These metal or plastic rings are used to attach cables, tow, moor or hold cargo, but improperly mounting them can cause the boat to tear off under load or even damage material. Unlike rigid aluminum or fiberglass hulls, PVC fabric requires a special approach: conventional welding or bolt mounting will not work here.

In this article, we will discuss stage-by-stage From the selection of crims and adhesives to the testing of the finished mount. surfaceIt's the one that's 80 percent strong, and you'll also learn what mistakes beginners make most often (like ignoring degreasing or using the wrong glue) and how to avoid them. Honda Marine, Bark and Wingsand the experience of professional installers.

What Rims are suitable for PVC boats: types and materials

Not all Roma are equally effective on inflatable boats. material, construction and loadAnd the key options are the ones that they can handle.

• 🔹 Stainless steel It's the safest option for seawater. AISI 316 They are resistant to corrosion and can withstand loads of up to 500 kg. Suitable for heavy boats and towing.
• 🔹 aluminum It is lightweight and budget, but less durable, and is ideal for small boats (up to 3.5 m) and for fastening lightweight loads (for example, anchors weighing up to 10 kg).
• 🔹 Plastic (polyamide, ABS) It is used for temporary or auxiliary attachments, not suitable for towing, but convenient for fixing covers or nets.
• 🔹 Composite rifts They combine the strength of metal and the lightness of plastic, and they're often used in tourist boats. Sevylor or Intex.

By design, the Rims are divided into:

• 🔧 Open. - with a detachable ring (convenient for fast fast fastening / untie of the cable).
• 🔧 Closed. All-metal (more reliable, but require the rope to be pulled through the ring).
• 🔧 Turning - with a hinge that allows you to change the load angle (ideal for towing).

For PVC boats, the optimal rims with flat-base At least 50 cm2, this increases the adhesive area. Avoid sharp edge models, which can cut through the material under dynamic loads.

Choosing adhesive: What really works for PVC

Mistakes in glue selection are the main reason why the dips break off after a few months. PVC fabric requires specializedcapable of withstanding:

• 🌡️ Temperature differences (from -30 C to +60 C).
• 💦 Constant contact with water and UV radiation.
• 🔄 Dynamic loads (trucks during towing).

The best options for glue for rum:

The name of the glue	Type	Seizure time	Break-off strength	Price (for 50 ml)
Bostik 2402	Polyurethane	24 hours.	up to 40 kg/cm2	~800 ₽
Kernil Stick	Polychloroprene	12 hours.	up to 35 kg/cm2	~650 ₽
Crystal moment	Cyanacrylate	4 hours	up to 25 kg/cm2	~300 ₽
UHU Plus Endfest 300	epoxy	48 hours.	up to 50 kg/cm2	~1200 ₽

Critically, the adhesive must be compatible with PVC and not contain solvents (acetone, toluene) that destroy the boat’s material. For example, popular Superglue. (Cyanoacrylate) gives a fragile compound that cracks when you're under load. For maximum strength, experts recommend two-component compounds, for example, Bostik 2402 or UHU Plus.

⚠️ Attention: Never use adhesives for rubber (for example, 88th) - it does not provide adhesion with PVC and flakes off over time. Also avoid thermal glue: it melts in the sun and loses strength.

Preparation of the boat and the rift for bonding

Even the most expensive glue can't save you if you don't prepare the surface properly.

1. Cleanup. Rinse the installation site with a soapy solution, then rinse with fresh water. Remove the salt, sand and greasy stains.
2. Degreasing. Wipe the surface. isopropyl (concentration 90%+) or a special degreasing agent for PVC (for example, Loctite 7063). Don't use acetone!
3. Cleanup. In light circular movements walk along PVC sandpaper P400-P600 It's going to increase the area of the clutch. Don't overdo it, just remove the gloss without damaging the fabric.
4. Drying. Dry the surface with a hair dryer at a temperature not higher than 50 ° C or leave for 1-2 hours at room temperature.

Preparation of the Rima:

• 🧼 Clean the base of the roe from the factory lubricant (if there is) with alcohol.
• 🔍 Check if there is any rust on the metal (for steel fry). WD-40 and brush it.
• 🖌️ Apply a thin layer of glue on the base of the mug and let it dry for 5-10 minutes (this is called "sticking").

⚠️ Attention: If the boat is new, it needs to be run around before installing the rums, inflate it 2-3 times and blow it away so that the PVC fabric takes its working shape, which will reduce the risk of deformation of the adhesive seam.

Step-by-step instructions for gluing the fry

Now, to the most critical stage, you're going to need to:

• 🔧 Flat-based roms.
• 🧴 Selected glue (see table above).
• 📏 Line and marker for marking.
• 🪛 Strubs or heavy objects for fixation.
• 🧤 Gloves (glue can irritate the skin).

Step 1. Markup. Put it on the boat and mark the outline of the base.

• 📍 The rhyme is symmetrically positioned relative to the axis of the boat.
• 🚤 The distance from the edge of the balloon is at least 10 cm (otherwise the glue will not withstand the load).
• 🔄 If you have multiple slacks, keep the same distance between them.

Step 2. Apply the glue. Put the glue on. thin-layer (1-2 mm) on the base of the riddle and the circled area on the boat. Bostik) one layer is sufficient for epoxy (UHU Plus) two with intermediate drying for 15 minutes.

Step 3. Fix. Press tightly against the boat and fix with rods or put a bag of sand on top (weighing at least 5 kg).

Step 4. Drying. Leave the boat in a warm (18-25°C), dry place for the time specified in the glue instructions. The minimum drying time is 24 hours, even if it says less on the package, and for epoxy adhesives, it takes up to 48 hours.

Testing of fastening: how to check reliability

Don't rush to load the pits immediately after drying!

1. Visual examination. Check if there is any under the base of the rym:
• 🔍 Air bubbles.
• 🔍 Uneven glue projections.
• 🔍 Cracks or flaks at the edges.

Static load. Hang a weight of 2 times the calculated weight (for example, if the rum is designed for 50 kg, hang 100 kg). Leave for 10 minutes. If the mount is not deformed, the test is passed.

Dynamic load. Pull the rope on the scallop with a force of ~70% of the maximum force, for example, for a 100 kg distillery, pull with a force of 70 kg. If the glue is not cracked, you can use it.

If the rum is intended for towing, do an additional test:

4. A simulated towing. Attach the boat to another (or to the car) and drag at low speed (2-3 km / h) through the water for a distance of 50 meters. After checking the temperature of the base of the rim - if it is heated, then the glue will not withstand a long load.

⚠️ Attention: If the glue has become sticky or has changed color after the tests (yellowish spots appear), this is a sign of poor quality composition, which must be removed and re-glued using another glue.

Common Mistakes and How to Avoid Them

Even experienced boaters sometimes make mistakes when installing the frymes.

• 🚫 Ignoring degreasing. The fat layer on PVC reduces adhesion by 40-60%. isopropylNot household solvents.
• 🚫 Savings on glue. A thin layer of glue will not provide sufficient strength. The optimal thickness is 1-2 mm.
• 🚫 Installation on a dirty or wet surface. Even drops of water under the sludge lead to detachment after 1-2 months.
• 🚫 Use of squirrels without padding. The metal base can rub PVC when vibrating. Always put a rubber or neoprene pad 1-2 mm thick.
• 🚫 Load until full drying. Even if the glue is “grabbed” after 4 hours, complete polymerization takes up to 48 hours.

Another common problem. rimFor example:

• 📍 Too close to the seam of the balloon, the risk of rupture under load.
• 📍 In curved areas, the glue is worse due to uneven pressure.
• 📍 Without taking into account symmetry, a boat can behave unpredictable when towing.
What do I do if I'm out of shape?

If the rum is torn off with a piece of PVC, the damage site should be reinforced with a patch of the same material. UHU Plus) and a fiberglass gasket, install the new rum at a distance of not less than 15 cm from the old mount.

Alternative ways of fastening the squirrels

Adhesives are not the only option. Let's look at the alternatives.

• 🔧 A bolt mount with a gasket. Suitable for boats with a hard bottom (for example, Bark 320A hole is drilled into the PVC fabric, a bolt with a wide washer and a rubber gasket is inserted, and then a nut is fixed. Minus: The leakage of the balloon is broken.
• 🔧 Velcro straps based on 3M VHB. A special double-sided tape can withstand a load of up to 20 kg / cm2. It is suitable for lightweight slimes (for example, for fastening covers). Plus: It does not require drying, it can be removed without a trace.
• 🔧 Textile loops. The kapron cord loops sewn into the PVC fabric (diameter 6-8 mm) replace the lightweight rims. Minus: They're not suitable for towing.

For boats with aluminum-bottom can be used combination:

1. Stick the PVC part of the balloon.
2. Fix it additionally with a bolt to the hard bottom through the gasket.

This increases reliability by 30-40%, but requires careful drilling.

FAQ: Answers to frequent questions

❓ Can I put a slap on an old boat with scuffs?

Yeah, but first, you need to regenerate the PVC tissue, clean the installation site of dirt, defat and apply a thin layer. liquid PVC (for example, Composite PVC glueAfter drying (4-6 hours), the bark can be glued according to the standard scheme.

❓ How many rums do you need to tow a boat?

At least 2 - one on the bow and aft. For boats longer than 3.5 m, 4 rims are recommended (in addition on the sides), the distance between the bow rims should be at least 30 cm for even distribution of the load.

❓ How to remove the poop without damaging the boat?

Carefully tuck the base of the rim with a plastic spatula, preheated with a dryer (temperature not higher than 60 ° C. Remove the glue residues with a solvent for PVC (for example, Loctite SF 7520Do not use a knife or metal tools!

❓ Can I make a squirrel in the winter?

Yes, but only in a heated room (at least 18°C) and sub-zero temperatures, the glue loses its elasticity and the connection becomes brittle. If the boat is stored in an unheated garage, move the work to spring.

❓ What is the strongest glue for seawater?

It's optimal for salt water. Bostik 2402 or Sikaflex-291These adhesives are resistant to salt corrosion and UV radiation. After the frying is installed, then you can coat the adhesive seam with a thin layer. polyurethane for protection.
