How to glue rum to a PVC boat: a step-by-step guide with photos and tips

Installing a PVC digger on a boat is a challenge that every inflatable boat owner faces sooner or later. Without this simple but important element, it's hard to imagine a safe mooring, transportation or even towing. improper installation of the diamond can lead to the separation of fittings At the most inopportune moment, such as a strong jerk or agitation on the water, in this article we will learn how to avoid mistakes and secure it so that it lasts more than one season.

Many PVC boat owners mistakenly believe that it is enough to simply glue the pod on the "eye" using the first glue they get. The quality of bonding depends on many factors: PVC material, adhesive mix, surface preparation and even weather conditions during work, and we've collected proven recommendations from boat repairers and accessories manufacturers to keep your rum infused.

Why do you need a PVC boat and what types are there

A rim (or nut) is a metal or plastic ring with a mounting pad that serves as a focal point for a cable, safety flap or towing rope. On boats, PVC rims are installed in several key locations:

• 🔹 Nose part - for mooring to the pier or towing.
• 🔹 Aft part If the boat is equipped with an engine, a safety line is attached here.
• 🔹 board - for fixing cargo or additional accessories (for example, sonar).
• 🔹 Tranza rifts - especially for motor boats to fix the engine.

By design, the Rims are divided into:

• 🔧 Open. Simple rings without a lock, suitable for temporary fixation.
• 🔧 Closed. (with a latch) - more reliable, exclude spontaneous disconnection of the cable.
• 🔧 Recessed - mounted flush with the surface of the boat, do not cling to the tackle.
• 🔧 Regulated - with a rotary mechanism to change the angle of tension.

For PVC boats, the most commonly used rips from stainless steel stamps AISI 316or aluminum-alloy Plastic diamonds are cheaper, but they're only suitable for light loads, like mounting a case.

What glue to choose for a squirrel on a PVC boat

The quality of the glue depends on up to 80% of the strength of the mounting of the diamondPVC material in boats requires special compounds that provide an elastic and water-resistant compound, and a regular "moment" or superglue is not suitable here, they will eventually crack under the influence of water and UV rays.

The best options for glue for rum:

Type of glue	Brand/model/model/model/model/	Advantages	Deficiencies	Price (for 50 ml)
Polyurethane	Bostik 2402, Saba Marine	High elasticity, resistance to salt water	Long drying time (24+ hours)	600–900 ₽
Polychloroprene	Clay 88-HT, UHU Plus Endfest 300	Quickly grasping, suitable for emergency repairs	Less elastic, may turn yellow over time	300–500 ₽
Two-pronged	Poxipol, Loctite Hysol 9466	Maximum strength, suitable for heavy squirrels	Difficult to remove during dismantling, requires precise mixing	1200–1800 ₽
Specialized for PVC	Vinyl Cement, Clifton Adhesives	Optimized for PVC boat, UV-stable	Hard to find in regular stores	800–1500 ₽

For most tasks, it is sufficient polyurethane It provides a balance of strength and flexibility, and if the fry will be subjected to serious loads (for example, for towing), it is better to choose between the two. two-componentBefore buying, make sure that the package is marked. "for PVC" or "marine grade" (Navy class)

⚠️ Attention: Never use cyanoacrylate-based glue (superglue) or epoxy resin without plasticizers - they become brittle at low temperatures and can break off on impact.

Preparing the boat and the squirrel for sticking

Even the most expensive glue will not save you if you do not properly prepare the surface. 90% of failures in the installation of muds are associated with poor cleaning or degreasing PVC. Follow this algorithm:

1. Selection of location. The rump must be attached to flat-boatThe optimal distance from the edge is 5-10 cm. Avoid areas where PVC is already damaged or has been repaired.
2. Markup. Put a barbecue on the boat and circle it with a marker. If the barbecue is round, use a stencil. Check the markings on both sides of the boat for accuracy, and sometimes PVC can be deformed.
3. Cleanup. Wash the installation site thoroughly with soapy solution, then rinse with clean water. Remove any traces of salt, sand or old glue.
4. Degreasing. Wipe the surface. acetone or a specialized degreasing agent (PVC CleanerDo not use gasoline or solvent 646 - they can damage PVC.
5. Cleanup. Walk in easy motions to the place of the sticker sandpaper with grain content 220-320 (only for matte surfaces!) This will improve adhesion. For glossy PVC, no cleaning is needed.

The rum itself also requires preparation:

• 🧼 Wash it in warm water with detergent.
• 🧴 Be fattened with alcohol or acetone (especially if the rum is new - it may have factory lubrication).
• 🔍 Check the thread (if the rift is collapsible) - it should rotate smoothly, without jamming.

If you set the rhyme on swelling-boatMake sure that the pressure in the cylinder is nominal (usually 250-300 mbar). Too soft or pumped PVC can deform when glued.

Step by step instructions: how to glue rum to the PVC boat

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

• 🔧 Roma with a fastener
• 🧴 Selected glue (see table above)
• 🎨 A brush or spatula for adhesive application
• 📏 Line and marker
• 🧊 Goods (such as sandbags) for fixation

Step 1. Apply the glue.

Put the glue on. flat-layer On both surfaces to be glued: on the base of the dimp and on the PVC of the boat. For polyurethane adhesive, a layer of 0.5-1 mm is enough. If you use two-component adhesive, mix it according to the instructions (usually a ratio of 1: 1).

Step 2. Drying the first layer.

Let the glue dry for 10 to 15 minutes (exact time on the package), the glue should become sticky, but not liquid. This is called the "open exposure" stage, which is critical for maximum adhesion.

Step 3, fix the riddle.

Carefully apply the weight to the boat, combined with the markings. Press it with a force of 5-10 kg for 30-60 seconds. Then put the load on top (for example, a 5-pound weight) and leave for 2-4 hours. If you are large, use soft-plated rods to avoid damaging the PVC.

Step 4: Complete polymerization.

Do not overload the topping up during 24-48 hours At this time, the boat cannot be inflated, blown, transported or subjected to temperature changes. Ideal conditions for drying: temperature 18-25 ° C, humidity up to 60%.

What if the adhesive hit the visible part of the boat?

If the glue is not already frozen, remove it with acetone and a soft cloth. Use a special cleaner for dried stains (for example, Bostik RemoverDon't rub PVC with hard brushes, it will spoil the texture of the material.

⚠️ Attention: If you put a poop on blown-boatPVC can stretch and the rum will fall off after the pumping. Always mount the fittings on a rated pressure boat!

How to check the strength of the fastening of the frock

Before you go out, you need to test the reliability of the installation.

1. Visual examination. Check if there are any bubbles, detachments or glue excess around the cone. The edges should be flat, without gaps.
2. Manual test. Pull it in different directions with a force of 10-15 kg. It should not move or "play." Let's only allow a minimum backlash (up to 1 mm) due to the elasticity of PVC.
3. A load test. Hang a load of 20-30 kg (for example, a bucket of water) to the red for 10-15 minutes. If the mount is withstanding, you can increase the load to 50 kg.
4. Dynamic test. Pull a rope that's attached to the scallop, which is a simulated jerk when mooring, and a high-quality mount can withstand 3-5 of these jerks without any signs of detachment.

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

• 🚤 Attach the boat to another boat and give an easy ride (1-2 knots).
• 🔄 Check if the rod is shifted when the direction of thrust changes.
• 💦 After the test, examine the place of attachment for the presence of moisture under the glue seam (this is a sign of leakage).

If the tests fail, don't take any chances! Remove the crumb (neatly cutting the glue with a stationery knife), clean the surface and repeat the procedure with new glue.

Frequent mistakes and how to avoid them

Even experienced boaters sometimes make mistakes when installing the frymes, and here are the most common mistakes and ways to prevent them:

Mistake.	Effects of consequences	How to avoid
Use of inappropriate glue	The rump will fall off after 1-2 exits to the water	Only buy glue marked "for PVC" or "marine"
Sticking on a dirty surface	Weak adhesion, the glue won't catch.	Degrease PVC with acetone, not alcohol
Applying too thick adhesive	Long drying, risk of bubbles	The adhesive shall be not more than 1 mm thick
Ignoring the "open exposure"	The glue will not reach maximum strength	Always wait 10-15 minutes before fixing.
Setting the dice on the seam of the boat	The seam may disperse under load.	Hold your bark at least 5 cm from the seam

Another common mistake. low-temperature Under these conditions, the glue polymerizes slowly and does not gain full strength. If you have to work in cool weather, use it. cure-accelerator (for example, 3M Marine Adhesive Sealant 5200) and increase the drying time by 1.5 to 2 times.

It is equally important to avoid heat-up If the boat was in the sun, cool the PVC to room temperature before sticking, and overheating makes the material too elastic, and the rum may "sink" in the surface.

Alternative ways of fastening the diamond

Adhesive attachment is not the only option, and in some cases it is more appropriate to use mechanical methods:

• 🔩 Bolt mount. Suitable for boats with hard-bottomed or aluminum-platedPVC drills a hole, inserts a screw and locks a nut on the back. Minus: The leakage of the balloon is broken.
• 🧲 Magnetic squirrels. They are fastened without drilling, but they only hold light loads (up to 5 kg) suitable for temporary fixation of covers or tackles.
• 🔗 Textile loops. Stitched loops of strong cord (for example, Dyneema) glued to PVC and attached to them with scavenge, this method distributes the load over a large area.
• 🛠️ PVC welding. For professional installation, they are used hot-air (dryer with nozzle) and special PVC patches. It's reliable, but it takes experience.

Mechanical methods are inferior to the adhesive mount in tightness, but allow you to dismantle the frock when necessary. squirrel on motor boats where high strength is required.

FAQ: Answers to frequent questions

Can I put PVC on a boat in winter?

Technically, it can, but it's not recommended, and at temperatures below 10°C, the glue polymerizes slowly and may not gain full strength.

• Use a glue with a curing accelerator (for example, 3M 5200).
• Before work, warm up the boat and glue in a warm room (at least +15 ° C).
• Increase the drying time by 2 times.

The ideal time for installation is spring or early autumn, when the temperature is stable in the range of 18-25 ° C.

How many rums should I install on a PVC boat?

Minimum equipment:

• 1 nasal pome (for mooring).
• 1 stern pome (if there is a motor).

The best equipment for active use:

• 2 noses (front on the sides).
• 2 stern snare (for the engine and safety line).
• 2 side rims (for fastening the cargo).

For fishing or hunting, add 1-2 rips on the transom to fasten the sonar or lift.

How to remove old rum from a PVC boat?

Carefully cut the glue with a stationery knife, trying not to damage the PVC.

1. Treat the glue residues with a solvent (Bostik Remover or acetone.
2. Clean the surface with sandpaper (grain 320) to remove traces.
3. Apply to the former rym PVC-component (for example, Vinyl Repair Kit) to restore leakage.

If the PVC is damaged, stick it on top. patch-up It's the same material.

Can I paint with stain after installation?

Yes, but only after complete polymerization of the adhesive (after 5-7 days).

• 🎨 Acrylic paint metal (if steel is stained).
• 🎨 Powder coating (Put before installation).
• 🎨 Vinyl stickers - they don't damage the glue seam.

Do not use nitro paint or enamel on the solvent – they can eat the glue.

Which squirrels to choose for towing a PVC boat?

Towing requires a pouch with:

• 🔄 Closed ring. (to keep the cable from slipping off).
• 💪 Minimum load of 200 kg (indicated in the specifications).
• 🛠️ Reinforced anchorage (area not less than 50 cm2).

Best models: Harken 157, Ronstan RF5110or the domestic roma from Kovrov factory (Profi series)

Important: for towing, the pome should be attached not just glue, but bolts. (If the design of the boat permits).
