Professional Joint Preparation, Removal & Finishing

Soudal Sealant Tools help trades achieve cleaner, more consistent joints from the first stage of preparation through to the final finishing pass. Whether you're removing failed silicone, cutting a cartridge nozzle, shaping a fresh bead or cleaning up around the joint, using the right tool can save time & improve the finished result.

For builders, plumbers, glaziers, bathroom installers, roofers & maintenance teams, professional sealing involves more than applying material from a cartridge. The joint needs to be prepared correctly, the sealant needs to be controlled during application & the finished profile needs to suit the job.

Working through the complete sealing setup? Adhesives & Tapes covers the wider sealing & bonding range, while Hand Tools supports the preparation & installation work surrounding the joint.

What Are Soudal Sealant Tools?

Soudal sealant tools are purpose-built accessories for removing old sealant, preparing cartridges & joints, shaping fresh material & achieving a controlled finished profile.

The range supports several different stages of sealing work:

► Multi Tool — for pushing, pulling & scraping old sealant from joints
► Cartridge Cutting Tool — for safely opening cartridges & trimming nozzles
► Soudaglatt — a flexible joint-smoothing tool for professional finishing
► Silicone Spatula Kit — multiple profiling edges for smoothing & shaping different joint sizes
► Joint Finishing Solution — assists with smoothing freshly applied acrylic, silicone, SMX® & hybrid sealants

Each solves a different problem, which is why selecting by stage of work is more useful than simply buying another general-purpose scraper.

Removing Existing Sealant

A resealing job starts with what's already in the joint.

Soudal's Multi Tool is designed to remove old sealant by pushing, pulling or scraping. Its reusable design gives installers a dedicated option for removing existing joints before replacement material is applied.

The objective isn't simply to make the old bead disappear. The bonding area underneath needs to be exposed so its condition can be properly assessed.

Preparing the Cartridge

A clean joint still needs controlled material delivery.

The Soudal Cartridge Cutting Tool is designed for opening cartridges & trimming nozzles quickly. Nozzle preparation matters because the size & angle of the opening influence how much material reaches the joint.

An oversized nozzle can put down substantially more sealant than required, leaving the finishing tool to push excess material somewhere else.

Shaping Fresh Sealant

Soudaglatt & the Silicone Spatula Kit are designed for the finishing stage.

Their purpose is to help shape freshly applied sealant into a smoother, more repeatable joint profile.

The Silicone Spatula Kit provides multiple angles for different joint shapes, making it useful when one profile won't suit every corner, perimeter or gap on the job.

Finishing the Joint

Soudal Joint Finishing Solution is designed to assist the smoothening of freshly applied sealants & is suitable for acrylics, silicones, SMX® & hybrid sealants.

Used with an appropriate smoothing tool, it provides another level of control during the final finishing pass.

Follow the product directions rather than allowing finishing solution to dry unnecessarily on the sealant or surrounding surfaces.

Why Choose Soudal Sealant Tools?

The Finish Starts Before the Cartridge Opens

A clean bead isn't created during the final few seconds alone.

Poor preparation can leave old residue underneath. An incorrectly cut nozzle can dispense too much material. Inconsistent tooling can change the profile along the joint.

Treating the process as a sequence produces a more controlled result:

Remove → inspect → prepare → cut → apply → profile → clean.

That approach is particularly useful where:

► Existing silicone needs replacing
► The finished joint remains highly visible
► Long runs need a consistent profile
► Several corners or transitions are involved
► Different joint widths occur on the same job
► Surrounding surfaces need to remain clean
► Repeatable results matter across multiple installations

For wet areas where the visible sealant forms only one part of the moisture-control system, Waterproofing & Damp Proofing covers the wider waterproofing requirements behind the finished joint.

Common Applications

Bathroom & Shower Resealing

Failed silicone around showers, baths, vanities & tiled corners should be treated as a repair rather than simply another bead to cover.

Start by removing deteriorated material & inspecting the exposed joint.

Once the bonding surfaces are appropriately prepared, fresh sanitary sealant can be applied & shaped with a suitable finishing profile.

This is where a dedicated silicone smoothing tool becomes useful: highly visible bathroom joints quickly reveal changes in bead width, tool angle & edge quality.

Kitchen Benchtops, Sinks & Splashbacks

Kitchen sealing often involves narrow joints against finished surfaces.

Control matters.

Cutting the nozzle to suit the actual joint helps avoid laying an unnecessarily large bead, while a suitable profiling tool can keep the finished line consistent around sinks, splashbacks & benchtop junctions.

The aim is not to apply the most material.

It's to apply the appropriate amount in the appropriate place.

Windows & Doors

Perimeter sealing around frames often involves longer runs where small changes in pressure or angle become increasingly noticeable.

Before application, check whether the chosen finishing tool can pass around corners, hardware & frame details without forcing your hand into an awkward position.

For exterior openings where the seal forms part of the building envelope, Weatherproofing Supplies provides a relevant pathway for the wider moisture-protection job.

Roofing & Flashing Details

Roofing applications may not require the same decorative profile as an internal bathroom joint, but material control remains important.

Around flashing, penetrations & repair details, preparation tools help clear the working area while controlled application reduces unnecessary sealant spread across adjacent roofing surfaces.

Browse Roofing Materials & Sealants for broader roof repair work or Roof Sealants & Adhesives when the job specifically requires sealing or bonding exposed roof details.

Removing Failed Silicone & Sealant

Not every old joint fails for the same reason.

Once the material begins coming out, look for evidence of:

► Adhesion loss along one edge
► Cracking or splitting
► Persistent moisture
► Contamination
► Movement around the joint
► Previous sealant underneath
► Poorly prepared surfaces
► Damage to the adjoining substrate

Removal exposes the joint.

Inspection tells you whether simply replacing the bead is enough.

General Maintenance & Repairs

Maintenance crews rarely start with pristine new surfaces.

A repair may involve several generations of sealant, old residue, paint, awkward access & multiple substrate types.

A reusable sealant scraper, cartridge cutter & selection of finishing profiles can therefore be more useful than relying on one improvised tool for every stage.

Removing an Existing Joint?

Use a simple three-stage process:

Remove → inspect → prepare.

Take out the old material carefully enough to avoid unnecessary damage to the surrounding surface.

Then inspect the bonding edges.

A joint can look empty while still carrying a thin layer of residue exactly where the replacement sealant needs to bond.

Where cured silicone residue remains after mechanical removal, a compatible specialist remover may be appropriate. Always follow the product directions & confirm suitability for the surrounding substrate.

Cutting the Cartridge & Nozzle

Don't automatically cut the largest opening.

Start by considering the width of the joint & the amount of material required.

A controlled nozzle opening makes the bead easier to place & reduces the volume that needs to be removed during finishing.

The cut angle can also affect how comfortably the nozzle tracks along the joint.

A few seconds spent preparing the nozzle can save considerably more time during cleanup.

Choosing a Finishing Profile

Soudal's Silicone Spatula Kit provides multiple profile angles, allowing the finishing edge to be selected around the joint rather than forcing one shape across every application.

Consider:

► Joint width
► Joint position
► Internal or external corner
► Adjoining substrates
► Required sealant depth
► Accessibility
► Final appearance

For construction joints, profile selection doesn't replace correct joint design. Follow the sealant manufacturer's requirements for dimensions, backing material & application.

Using Joint Finishing Solution

Joint Finishing Solution is intended to make freshly applied sealant easier to smooth.

Apply it according to the product directions & use it with the appropriate finishing method.

Avoid leaving unnecessary residue to dry on the sealant or adjacent materials.

The finishing solution assists the tooling process—it doesn't replace correct surface preparation, appropriate sealant selection or proper joint dimensions.

Finishing Tool or Applicator Gun?

These tools work together but perform different jobs.

Applicator gun: gets material out of the cartridge or sausage.

Cartridge cutter: prepares the package & nozzle.

Finishing tool: shapes the fresh bead.

Removal tool: prepares an existing joint for replacement.

A professional sealing setup may require all four.

Expert Tips

Test the Finishing Tool on the Empty Joint

Before applying sealant, run the selected profile along the joint.

This simple check can reveal:

► A corner you can't reach cleanly
► A tap or fitting obstructing your hand
► A profile that's too large
► Changes in joint width
► Frame details affecting the tool angle
► Areas needing more preparation

Solve those problems while the joint is dry.

Remove old material thoroughly. New sealant needs properly prepared bonding surfaces rather than a cosmetic layer over failed material.

Inspect before resealing. If moisture, movement or substrate damage caused the original problem, another bead alone may not solve it.

Cut the nozzle for the joint. Excessive material creates unnecessary finishing & cleanup.

Work in manageable sections. Don't apply more material than can be properly tooled within the product's stated working time.

Maintain a consistent finishing angle. Changing the tool position changes the profile.

Choose the profile deliberately. Use the spatula edge that suits the joint rather than simply reaching for the same one every time.

Check both sides of the bead. A smooth centre doesn't guarantee clean, properly finished edges.

Avoid excessive reworking. Once the profile is correct, repeated passes can disturb the finish.

Clean reusable tools promptly. Removing uncured material is considerably easier than dealing with hardened residue before the next job.

Protect yourself during removal & cleanup. Sealants, removers & cleaning products can have different handling requirements.  Chemical-Resistant Gloves provides a relevant pathway when selecting suitable hand protection.

Before the Fresh Bead Goes Down

Confirm:

► The failed sealant has been removed
► The reason for failure has been considered
► Bonding surfaces are sound
► Residue isn't interfering with the joint edges
► Surface conditions suit the selected sealant
► The cartridge nozzle is cut appropriately
► The chosen finishing profile suits the joint
► The tool can reach the full application area
► The bead can be finished within the available tooling time
► Surrounding finished surfaces are protected where necessary

Preparation should be complete before application begins.
