Sticking the inside of an aluminum boat is not just a matter of comfort, but also of protecting the hull from corrosion, noise and mechanical damage. aluminum-magnesium alloys (for example, "Kazanka", "Ob", "Wings of the Soviets") often face condensation problems, which accelerates metal oxidation, and constant waves create an unpleasant crash. Proper coating solves these problems, but errors in the choice of materials can lead to detachment, mold or even deterioration of the boat's handling.

In this article, we will discuss 7 Verified Materials For interior decoration, we compare them in terms of price, durability and complexity of installation, and also tell you how to avoid typical errors. compatibility of adhesive compositions with aluminum This is a point that is often overlooked, although it is critical for the durability of the coating. If you plan to paste the boat yourself, here you will find step-by-step instructions with nuances for different types of boats. small-timer before boats).

Why not leave an aluminum boat uncoated?

Bare aluminum in a boat is not only a discomfort, but also a safety risk, and here are three key issues that internal plastering solves:

  • 🔊 Noise and vibration: Without coverage, each wave is given by a loud knock in the body. 80 dB It’s like a working vacuum cleaner next to your ear.
  • 💧 Condensation and corrosion: The temperature difference between the water and the air in the boat causes droplets on the metal. point-corrosionEspecially in the welding areas.
  • ⚠️ Slip and injury: Wet aluminum is becoming dangerously slippery. 12% of falls overboard Small boats are caused by slipping passengers.

And the unprotected metal wears out faster from the abrasive effects of sand, fishing gear and shoes, for example, in boats. "Diver." or "Aqualine."The inner surface, which is often used for hunting, wears out in 2-3 seasons if it is not protected.

⚠️ Attention.If you operate a boat in salt water, the lack of coating will accelerate corrosion in the water. 3-5 timesChlorides break down the protective oxide film of aluminum, opening up the deep layers of metal.

Top 7 materials for pasting: comparison of pros and cons

The choice of material depends on the budget, the type of boat and operating conditions, and we tested popular options and ranked them according to the following criteria: noise insulation, moisture resistance, durability and ease of installation.

Materials Noise insulation Moisture resistance Term of service Price per m2 Difficulty of installation
penofol (followed) ⭐⭐⭐⭐ ⭐⭐⭐⭐ 5-7 years 300–500 ₽ Low.
isolone (Plastic foam) ⭐⭐⭐ ⭐⭐⭐⭐ 4-6 years 250–400 ₽ Low.
Vibrosplast (bitumenous) ⭐⭐⭐⭐⭐ ⭐⭐⭐ 3-5 years 400–700 ₽ Medium
sea-carpet ⭐⭐ ⭐⭐⭐⭐⭐ 7-10 years 800–1500 ₽ High.
Polyurethane foam sheet ⭐⭐⭐⭐⭐ ⭐⭐⭐ 8-12 years 600–1200 ₽ High.

For most owners, the best choice is foamfool or isolyte They are cheaper, easier to install and do not require special tools, but if the priority is maximum noise insulation (for example, for the use of electronic equipment). motorboats), worth considering vibroplate or polyurethane.

Penofol and isolone: a budget solution for noise insulation

These two materials are the ones that lead in terms of price/quality. polyethylene with closed pores, which does not absorb water and extinguishes vibrations well. penofol It also has a foil layer that reflects heat, which is important for winter fishing.

Advantages:

  • 💰 Low priceThe 3.5 m long boat will cost a lot of money. 3 000–5 000 ₽.
  • 🛠️ Simple editing.You can glue on nail-bag Or double-sided scotch.
  • 🔄 Easy dismantlingIf necessary, the coating is removed without damage to the aluminum.

Disadvantages:

  • ❌ Low abrasive resistance: Quickly wears off shoe soles or tackles.
  • ❌ Weak defense against blowsIt will not save you from dents when heavy objects fall.

Use glue for installation "Crystal Moment" or «Tytan Professional» They don't react with aluminum and they don't lose their elasticity when they're hot. degrease Acetone or white spirit.

Degrease the surface with solvent |Clean the rust with sandpaper (P120)|Application of a primer for aluminum (e.g., Zincrometal)| Dry the boat within 24 hours Mark and cut materials with a margin of 2-3 cm->

Vibroplastics and bitumen materials: maximum noise insulation

If your boat is equipped with a powerful motor (from the 30 hp), conventional materials can't handle vibration. bitumensuch as Vibrosplast or bimastThey consist of a layer of bitumen mixed with mineral fillers and aluminum foil.

Where to apply:

  • 🛥️ transom parts (at the motor) - here the vibration is maximum.
  • 🔧 Seat anchorages - prevents rattling.
  • 🌊 Bottom in the nose - extinguishes the waves.

Bitumen materials require heating It's a tight fit, but it makes it harder. It's important not to overheat the coating, because it's hotter. 120°C The bitumen starts to flow.

⚠️ Attention.Bitumen materials cannot be used in places where there is a possibility of contact with gasoline or oil (for example, under a fuel tank).

For boats with stationary (for example, Wind 8M.) recommend combining vibroplastics + foamThe first layer extinguishes vibration, the second - protects against condensation.

Carpet and artificial leather: premium options for comfort

If you are willing to invest in durability and aesthetics, pay attention to the quality of your life. sea-carpet or leather (for example, AlcantaraThese materials are used in premium yachts and boats, but are also suitable for aluminum boats.

The advantages of sea carpet:

  • 🌊 Absolute moisture resistanceIt doesn't rot or mold.
  • 👟 Anti-slip surfaceIt is safe even in wet shoes.
  • 🎨 Wide selection of colors: You can choose the design of the boat.

Cons:

  • ❌ High price.From 1,500 /m2.
  • ❌ Complicated editingRequires a professional tool (heat pistol for stretching).

Use the carpet to fix the carpet. glue-spray 3M Super 77 It's a uniform distribution, and it doesn't leave any lumps. polyurethane (for example, UHU Plus Endfest 300), since it retains elasticity.

How to save on premium materials?

Many stores sell remnants of sea carpet for 30-50% lower. Look for deals marked "flip" or "unconformed" - often pieces of 1×2 m, which will be enough to paste a small boat. "Textilmash" in Moscow) and save up to 20%.

Polyurethane foam: a universal solution for tuning

This material is often used in autotuningBut it's also great for boats. polyurethane (PPU) is of different densities:

  • 25-30 kg/m3 - for noise insulation;
  • 40-60 kg/m3 - to protect against blows.

Benefits of PSP:

  • 🛡️ Impact resistance: Can withstand a drop in weight to 50 kg No deformation.
  • 🔇 Noise insulation: Absorbing until 90% vibration.
  • 🔥 Heat resistance: Does not melt at temperatures to 150°C.

For boats it is better to choose sheets thick 10–20 mmYou can fix them on foaming or polyurethaneIt's important to leave gaps. 2-3 mm between the sheets to compensate for temperature expansion.

⚠️ Attention.: When pasting the bottom with polyurethane foam, check that the material does not cover drainageOtherwise, the water will accumulate and the boat will become less stable.

Step by step: how to paste the boat yourself

The process of scoring can be divided into 5 stagesWe will look at a universal scheme that is suitable for most materials (except for premium versions like carpet).

Tools required:

  • 🔧 Scissors or a stationery knife;
  • 🧴 Degreasing agent (acetone, white-spirit);
  • 🖌️ A brush or a roller for glue;
  • 📏 Roulette and marker;
  • 🧹 A dust brush.

Step 1: Surface preparation

  1. Remove the old coating (if any) with a spatula.
  2. Clean the rust with sandpaper P120–P180.
  3. Degrease the surface and apply a primer for aluminum (for example, Zincrometal).

Step 2. Open up the material.

  • Take the measurements off the boat by adding a 2-3 cm I'm on the pass.
  • Cut the parts according to the pattern, given the curves of the body.
  • For complex areas (for example, transoms) use heat-pistol For molding.
💡

If you paste the boat with the ribs of stiffness, make incisions in the material at an angle of 45 ° - this will help to avoid folds and ensure a tight fit.

Stage 3: Applying glue

  • Apply the glue on the aluminum point-point (for lightweight materials) or solid (for heavy ones, for example, polyurethane foam).
  • Wait. 5-10 minutesAnd then the stain will dry a little (this will improve the grip).
  • Press the material to the surface, smoothing from the center to the edges.

Step 4: Finishing

  • Cut the excess material at the edges.
  • Roll the coating roller to remove air bubbles.
  • If necessary, seal the joints. aluminum-scotch.

Stage 5: Drying

  • Don't operate the boat. 24-48 hours (The time depends on the type of glue).
  • Avoid getting water during the period. 3-5 days.
💡

The most common mistake when pasting is saving on glue. Cheap compounds (like PVA) can't withstand moisture and temperature changes. Use only specialized adhesives for aluminum and plastic!

Frequent mistakes and how to avoid them

Even experienced boaters make mistakes that shorten the life of the cover. TOP-5 misses And how to prevent them:

  1. Ignoring primer

    Aluminum is oxidized in air, and without soil, the glue is not very fast. epoxy (for example, Dulux Trade).

  2. Wrong glue choice

    Water-based adhesives (e.g., bustilate) is destroyed by moisture. For boats only suitable polyurethane or rubber compounds.

  3. Wet-surface pasting

    Even drops of condensate reduce adhesion. at least 12 hours before work.

  4. Absence of ventilation gaps

    If you completely seal the bottom, it will accumulate moisture under the material. 5-10 mm in the nose.

  5. Use of household scotch

    The regular Scotch will fall off in a week. aluminum or reinforced scotch.

If you have bubbles after the pasting, don't try to puncture them, it will only aggravate the problem. liquid-latch (for example, "Moment Herment.").

FAQ: Answers to frequent questions

Can I put a foam on the boat?

No, foam is not a good fit, it crumbles, it absorbs water, it's not strong enough, and it can also be a hotbed of mold. polyethylene (isolone, foam foam) or polyurethane.

Which glue is better for aluminum?

Best options:

  • Tytan Professional Alu - for light materials (penofol, isolone);
  • UHU Plus Endfest 300 For heavy (foam, rug, etc.);
  • 3M Scotch-Weld DP8005 Premium materials (artificial leather).

Avoid glues based on the acetate (for example, "The Universal Moment") — they corrode aluminum over time.

Do I need to paste a transom?

Yes, but with reservations:

  • If you outboard- Plug on the transom. vibrating on 20-30 cm It's going to lower the vibration.
  • For stationary use polyurethane thickness 15–20 mm.
  • Don't close. motor-holding - Leave access for maintenance.

How much does it cost to put a boat on the service?

Prices depend on the size of the boat and the material:

Type of boat Penofol/Isolon Vibrosplast Carpet
Small-time (3-4 m) 5 000–8 000 ₽ 8 000–12 000 ₽ 15 000–20 000 ₽
Boat (5-6 m) 10 000–15 000 ₽ 15 000–25 000 ₽ 30 000–50 000 ₽

You can save money by buying materials yourself and paying only for the work (usually). 50–70% from the full cost).

How to take care of a covered boat?

Care tips:

  • After every exit wash the boat with fresh water (Especially if you are in salt water).
  • Use it for cleaning. soft detergent (for example, "Shine-Aluminum.").
  • Once a season, treat the coating silicone - it'll prevent cracking.
  • Avoid. lip-spin - they scratch the material.
