Control Every Bead, Bond & Fill

Soudal Applicator Guns give builders, installers, maintenance crews & workshop technicians better control when dispensing sealants, adhesives, chemical anchors & gun-grade polyurethane foams. Choosing the right sealant applicator gun comes down to what you're dispensing, how it's packaged & how much control the job demands.

A standard cartridge of sealant doesn't place the same demands on a gun as a thick construction adhesive. A 600mL sausage needs a completely different barrel, while chemical anchors & PU foam have their own dispensing systems.

That's why the starting point isn't simply “Which gun is strongest?” It's cartridge or sausage, material viscosity, application volume, access & frequency of use.

Working with sealants or bonding products? Adhesives & Tapes covers the wider bonding & sealing job, while Waterproofing & Damp Proofing provides a useful pathway when controlled sealant application forms part of wet-area or moisture-management work.

What Are Soudal Applicator Guns?

An applicator gun converts trigger pressure into controlled material flow from the package to the joint, fixing or cavity.

Soudal's range covers several distinctly different dispensing jobs rather than trying to make one caulking gun handle everything.

Cartridge Guns

Cartridge guns are the familiar choice for cartridge-packed sealants, adhesives & fillers.

Soudal's Dripless Skeleton Gun provides a lightweight trade option with automatic pressure release designed to reduce unwanted material flow after the trigger is released.

When thicker material increases extrusion resistance, a heavy-duty adhesive applicator gun provides greater leverage. Soudal's Dripless Heavy Duty Cartridge Gun is designed for high-viscosity adhesives & sealants where a light-duty mechanism may require unnecessary effort.

600mL Sausage Guns

Foil sausages don't fit a conventional skeleton gun.

A 600mL sealant gun encloses the foil pack inside its barrel, with the plunger pushing material towards the nozzle as the trigger is operated.

Soudal's heavy-duty sausage applicator is designed around this larger format, with smooth operation, a substantial handle & trigger & interchangeable barrel options.

For trades running long beads or consuming larger volumes of sealant, the sausage format can also mean fewer material changes during the job.

Chemical Anchor Guns

Chemical anchoring creates another dispensing requirement entirely.

Soudal's 380mL Chemical Anchor Gun is designed around compatible anchoring cartridges, providing the controlled pressure required to move the resin components through the mixing nozzle & into a properly prepared fixing hole.

The applicator is only one component of that system. Structural Fasteners & Bolts covers the wider structural fixing pathway.

PU Foam Guns

Gun-grade polyurethane foam doesn't use a conventional sealant cartridge.

A dedicated PU foam gun connects to a compatible foam canister & allows the installer to regulate output into gaps, cavities & openings.

Soudal offers different foam-gun configurations, including extended-reach options for applications where the joint is difficult to access directly.

Pneumatic Applicator Guns

Now change the workload from three cartridges to thirty.

Repeated manual trigger operation becomes a much bigger consideration.

Pneumatic applicators use compressed air to assist material dispensing, making them particularly useful in workshops, production environments & larger installation jobs where cartridges or sausages are being applied repeatedly.

Why Choose Soudal Applicator Guns?

The Product Does the Sealing. The Gun Controls How It Gets There.

An expensive cartridge won't automatically produce a clean bead.

Jerky trigger movement can create inconsistent material flow. Poor leverage makes thick adhesive harder to dispense. Continued pressure after the trigger is released creates mess & waste. & no amount of force will make the wrong cartridge format fit the gun.

Choose the applicator around the work being done.

For Builders & General Installers

Working mainly with cartridge-packed sealants, fillers or construction adhesives?

Start with a manual cartridge gun, then move towards a heavier-duty model when product viscosity or daily workload demands greater leverage.

For Joint-Sealing Crews

Long runs can make 600mL sausages particularly practical.

A dedicated sausage gun accepts the larger foil format & reduces the need to stop repeatedly for smaller cartridge changes.

For Structural Fixing Work

Chemical anchors require the correct cartridge arrangement, mixing nozzle & applicator.

Don't assume a standard caulking gun is suitable simply because the package looks similar.

For Window, Door & Foam Installers

Gun-grade PU foam requires its own applicator.

A dedicated foam gun gives greater control over output, while extended-reach configurations can help when the target area is difficult to reach.

For Workshops & Repetitive Production

When material dispensing happens throughout the working day, pneumatic equipment can reduce repeated manual trigger effort.

For businesses already using compressed air, Air Tools & Compressors connects the applicator with the supporting workshop system.

Common Applications

Sealing Construction Joints & Gaps

Silicone, acrylic, hybrid & other cartridge-applied sealants benefit from controlled material flow.

A smooth trigger action combined with steady movement along the joint helps lay a manageable bead before tooling, while a dripless mechanism can reduce the unwanted material tail that sometimes follows trigger release.

Dispensing High-Viscosity Adhesives

Thick construction adhesive quickly reveals whether an applicator has enough leverage.

A professional caulking gun intended for demanding trade use can make heavy material easier to dispense consistently than a lightweight gun designed primarily for lower-resistance products.

This becomes particularly noticeable across long adhesive runs, repetitive bonding or colder conditions where some materials become harder to extrude.

Applying 600mL Sealant Sausages

Larger-volume joint sealing often favours the 600mL sausage format.

The foil pack sits inside the applicator barrel rather than a skeleton frame, allowing the gun to push material towards the nozzle as the trigger is operated.

For crews applying metres of sealant at a time, fewer pack changes can make the format practical.

Installing Chemical Anchors

Chemical anchoring is a system, not simply a cartridge of resin.

The compatible applicator pushes the resin components through the mixing nozzle before the mixed material enters the prepared hole.

The fixing, hole diameter, cleaning method, substrate, resin, embedment depth & curing requirements still need to match the installation.

Applying Foam Around Windows & Doors

A conventional sealant gun stops being relevant once the product changes to gun-grade PU foam.

Dedicated foam applicators give the installer greater control when filling suitable joints, cavities & openings around construction details.

Soudal's extended-reach foam-gun configuration uses a 1 metre barrel, providing another option where normal hand reach won't comfortably place the nozzle where the foam is required.

Repetitive Workshop Dispensing

A manual gun has obvious advantages: it's simple, portable & doesn't need an air line.

But high-volume work changes the calculation.

Where a workshop already has compressed air & operators repeatedly dispense the same cartridge or sausage material, pneumatic application can reduce the physical trigger work involved across the shift.

Product Selection Guide

Start With the Package, Not the Handle

Have the material in front of you?

Read the pack before comparing guns.

Package compatibility comes first. Extrusion resistance, workload & access come next.

Standard or Heavy-Duty Cartridge Gun?

For general cartridge-applied products, a quality skeleton gun provides a straightforward manual solution.

Move towards heavy-duty construction when the material becomes difficult to extrude or the applicator is being used repeatedly.

Soudal's heavy-duty cartridge gun is intended for thicker adhesives & sealants. Its dripless system automatically releases pressure when the trigger is released, helping reduce continued extrusion between sections of the job.

Cartridge or 600mL Sausage?

This is partly a product-format decision & partly a workload decision.

Cartridges can be convenient for smaller jobs, intermittent applications & frequent product changes.

600mL sausages become attractive where compatible products are being consumed in larger quantities & reducing pack changes matters.

Neither format is automatically better.

Ask how much material the job will consume before choosing the dispensing system around it.

Manual or Pneumatic?

Think in repetitions rather than minutes.

A manual gun used for a few beads is simple & highly portable.

Apply the same trigger movement hundreds of times across production work & the equation changes.

Pneumatic application becomes more attractive when:

► The dispensing operation is repetitive
► Cartridge or sausage consumption is high
► Compressed air is already available
► Consistent material delivery matters
► Reducing repeated manual trigger effort has practical value

Manual applicators remain useful where portability & independence from an air supply matter more.

Do You Need a Dedicated Chemical Anchor Gun?

Check the resin cartridge before reaching for the nearest caulking gun.

Soudal provides a dedicated 380mL Chemical Anchor Gun for compatible products, while other anchoring systems may use different cartridge arrangements.

Correct dispensing also needs to be considered alongside hole preparation, substrate condition, mixing & cure requirements.

Foam Gun or Built-In Applicator?

How often are you applying foam?

For regular installation work, a reusable foam gun provides controlled dosing from compatible gun-grade cans.

A built-in applicator system serves another purpose: convenient application without carrying a separate gun.

Regular installer → control & reusability matter more.

Occasional application → simplicity may matter more.

Choose around the actual workload.

Expert Tips

Check compatibility before opening anything. Cartridge diameter, sausage capacity, anchor format & foam connection should be confirmed before the product is opened.

Let viscosity influence the gun. If dispensing requires excessive force, determine whether the material needs a heavier-duty applicator rather than simply squeezing harder.

Cut the nozzle to suit the joint. An oversized opening can waste material & make a narrow bead difficult to control.

Keep your movement steady. Consistent travel along the joint often matters more than dispensing as quickly as possible.

Use drip control properly. Automatic pressure release can reduce continued flow, but clean trigger technique still matters at the end of each run.

Never force a blocked nozzle. Stop & identify the restriction. Excessive pressure can damage the cartridge, nozzle or applicator.

Keep the plunger clean. Cured adhesive around moving components can progressively affect operation.

Treat foam guns as reusable tools. Appropriate cleaning & storage matter because cured PU foam inside the applicator can make the tool unusable.

Check air pressure before repetitive pneumatic work. Too much pressure can make dispensing harder to control, while insufficient pressure can affect material delivery.

Keep chemical anchor mixing components organised. The applicator cannot compensate for incorrect resin mixing or poor hole preparation.

Store guns without damaging the working end. Bent plungers, contaminated barrels & damaged nozzles can turn up as dispensing problems on the next job.

Buying One Gun or Equipping a Crew?

The answer changes the buying decision.

An applicator used occasionally can prioritise straightforward operation & portability.

For installers dispensing material every day, look harder at:

► Trigger comfort
► Extrusion force
► Drip control
► Cartridge or sausage capacity
► Reload frequency
► Tool weight
► Cleaning requirements
► Joint access
► Availability of compressed air
► Number of operators using the equipment

Small inefficiencies become much more noticeable when multiplied across every bead, every cartridge & every installer.
