Professional Sealing for Construction, Glazing & Wet Areas

Soudal silicone sealants give builders, plumbers, glaziers, roofers & maintenance teams professional options for sealing bathrooms, kitchens, windows, roofing, gutters & general construction joints.

Choosing the right silicone starts with the job rather than the cartridge. Consider the substrate, moisture exposure, interior or exterior location & expected joint movement before selecting a formulation. Industrial Shed stocks Soudal silicones for sanitary applications, glazing, neutral cure sealing, roofing & general trade use.

Which Soudal Silicone Do You Need?

Not every silicone is designed to solve the same sealing problem.

A sanitary joint around a shower experiences regular moisture & cleaning. An aluminium window joint needs compatibility with the frame, glass & surrounding materials. A roof or gutter connection faces outdoor weather exposure. General construction joints may need to accommodate movement between different substrates.

Use the application as your starting point:

► Bathrooms, showers & kitchens — look for sanitary or bathroom & kitchen silicone suited to wet-area sealing.
► Glass & windows — choose a glazing-compatible silicone suited to the glass, frame & adjoining materials.
► Aluminium & sensitive substrates — consider an appropriate neutral cure silicone after checking product compatibility.
► Roofs, gutters & exterior joints — select a product intended for the relevant exterior application & materials.
► General construction & maintenance — use a compatible multi-purpose or construction silicone where a specialist formulation isn't required.

For exterior projects where the seal forms part of a wider weather-protection system, browse Weatherproofing Supplies.

Why Silicone Selection Starts With the Substrate?

Silicone remains flexible after curing, making it useful for suitable joints where adjoining materials can experience normal movement, temperature changes, vibration or moisture.

But flexibility alone doesn't make every silicone suitable for every surface.

Glass, aluminium, ceramic tile, coated metal, plastics, natural stone & other construction materials can have different compatibility requirements. A sealant that performs well on one substrate shouldn't automatically be used on another.

Before application:

► Identify both materials forming the joint
► Check whether the area is wet, dry, internal or exposed
► Consider expected joint movement
► Confirm the product is compatible with the substrates
► Check the manufacturer's application & curing requirements

This is particularly important when sealing coated surfaces, metals, natural stone or other materials where product compatibility may vary.

Neutral Cure vs Acetic Cure Silicone

The curing system is another important part of silicone selection.

Neutral cure silicone cures without releasing acetic acid & is commonly selected for compatible construction applications involving metals & other sensitive substrates.

Acetic cure silicone typically produces a vinegar-like smell while curing. It can perform well on compatible non-porous surfaces but isn't appropriate for every construction material.

Neither should be chosen simply because it is already in the toolbox.

Match the cure type to the application & check the individual Soudal product information before applying it to unfamiliar or sensitive materials.

Soudal Silicone for Bathrooms, Showers & Kitchens

Wet-area sealing requires a product suited to regular moisture exposure.

Sanitary silicone is commonly used around:

► Showers & shower screens
► Baths
► Basins & sinks
► Splashbacks
► Compatible tiles
► Plumbing fixtures
► Kitchen & bathroom joints

Choose a Soudal bathroom & kitchen silicone or other suitable sanitary formulation rather than relying automatically on a general-purpose product.

Surface preparation also matters. Soap residue, grease, moisture, old silicone & other contamination can interfere with adhesion.

Soudal Silicone for Windows, Glass & Aluminium

Glazing joints can connect materials that respond differently to temperature changes.

Glass & aluminium framing may therefore require a glazing silicone that remains flexible while being compatible with the surfaces forming the joint.

For aluminium frames & other sensitive construction materials, a suitable neutral cure silicone is commonly considered. However, the exact formulation should always be checked against the frame finish, glass & any adjoining materials.

This is especially important on coated or finished aluminium where assuming compatibility can lead to poor adhesion or an unsuitable seal.

Soudal Silicone for Roofs, Gutters & Exterior Joints

Roofing applications expose sealants to conditions that internal joints don't normally experience.

Rain, UV exposure, temperature changes & movement can all affect an exterior joint.

For roofing, guttering, flashing & similar work, choose a silicone or sealant specifically suited to the application & substrate.

Soudal Silicone for Construction & Maintenance

General construction sealing can involve window & door surrounds, fixtures, penetrations, metalwork & joints between compatible building materials.

Maintenance work adds another consideration: why did the previous seal fail?

A deteriorated bead doesn't necessarily mean the silicone simply reached the end of its life.

Failure can also be associated with:

► Poor surface preparation
► Residual old silicone
► Contamination or moisture
► Incorrect substrate compatibility
► Unsuitable product selection
► Excessive joint movement
► Exterior exposure beyond the intended application

Identifying the cause before resealing can help avoid repeating the same repair.

Preparing a Joint Before Applying New Silicone

Good silicone can't compensate for poor preparation.

When repairing an existing joint, avoid simply laying a fresh bead over failed material. New sealant needs suitable surfaces & application conditions to form a reliable joint.

► Remove loose, deteriorated or failed silicone
► Remove residue that may interfere with adhesion
► Clean & prepare the substrate as required
► Allow surfaces to reach the condition required by the product
► Check compatibility with both sides of the joint
► Confirm suitability for the expected exposure
► Apply & tool the silicone according to product instructions
► Allow appropriate curing before putting the joint into service

Sealant removal & preparation can expose workers to chemicals, sharp edges & contaminated material. Where appropriate hand protection is required, browse Chemical-Resistant Gloves.

Trade Tips for a Cleaner Silicone Finish

Plan the bead before opening the cartridge. Joint width, depth, movement & access can affect how the sealant should be applied.

Keep contamination away from bonding surfaces. Dust, grease, moisture & old silicone residue can compromise adhesion.

Tool while the silicone remains workable. Good tooling helps create a clean finish & establishes contact along the joint edges.

Don't mistake a surface skin for complete curing. The outside of the bead can become touch-dry while material deeper in the joint continues to cure.

Don't assume more silicone means a stronger joint. Correct joint design matters. Filling an unnecessarily deep cavity with sealant isn't automatically better.

Check before painting. Conventional silicone sealants generally aren't selected where the finished joint needs to accept paint. If painting is required, confirm that the chosen sealant is suitable.

Inspect exposed joints periodically. Roof, gutter & other weather-exposed seals should be checked for separation, physical damage or loss of adhesion during routine maintenance.
