Sealants

Soudal sealants cover every joint, gap, and surface found on a New Zealand building site, from MS sealant, silicone sealant and acrylics through to fire rated and automotive formulations. The range includes neutral, and hybrid polymer cures, so each product is matched to a specific substrate, movement class, and exposure condition rather than sold as a single all-purpose fix.

Match the sealant to the joint, not the other way round.

Soudal has been formulating sealants and adhesives since 1966 and is the largest independent European manufacturer in this category. Every NZ-specific sealant is tested against local UV and climate conditions, and BRANZ appraisal covers key products across the range. Trade users get technical datasheets and safety data sheets for every product, and the range is stocked through an established NZ hardware and trade merchant network. If the job calls for bonding rather than sealing, the Adhesives range or Expanding Foams may be a better fit. Not sure where to start, use the product selector tool.

How to choose the right sealant

Sealant selection comes down to four questions: what’s the substrate, how much will the joint move, will it be exposed to water or UV, and does it need to be painted.

Substrate compatibility. Acetic-cure silicones bond well to glass, ceramic, and non-porous surfaces but can corrode some metals and shouldn’t go on fresh masonry. Neutral-cure silicones and MS Polymer sealants are safe on a wider range of substrates, including natural stone, powder-coated aluminium, and most metals.

Movement capability. Expansion joints and façade joints need a sealant rated for higher movement accommodation, typically 20-25% for MS Polymer sealants and up to 50% for premium silicones. General interior joints and static joints can use a lower-movement mastic.

Exposure and location. Bathroom and kitchen silicones are formulated with additional fungicides to resist mould in humid rooms. Roof and gutter silicones carry stronger UV stabilisation for constant sun exposure. Applications with high UV exposure, such as around windows and doors, require sealants that have high movement capability and resistance to UV along with providing weather-tightness.

Paintability. Silicone sealants can’t be painted. If the joint needs to be painted over, an MS Polymer or polyurethane sealant is the correct choice.

Our sealant range includes

MS Sealants & Adhesives for paintable, high-tack sealing and bonding.
Silicone Sealants for wet areas, roofing, glazing, and general use.
Fire Rated Sealants for passive fire joints and service penetrations.
Automotive Sealants for windscreen bonding, panel sealing, and underbody protection.

Sealant Application guidance

Clean and dry the joint before application, removing dust, grease, and old sealant residue. Use masking tape either side of the joint for a straight finish and remove it before the sealant skins over. Tool the bead within the open time stated on the product’s technical datasheet, and don’t disturb the joint until the stated cure time has passed. For deep joints, use a backing rod to control bead depth and prevent three-sided adhesion, which restricts a sealant’s ability to move with the joint.

Sealants FAQs

What's the difference between silicone and MS sealant?

Silicone sealants offer higher UV resistance and flexibility but can’t be painted and have limited adhesion to some metals. MS Polymer sealants can be painted and bond to a wider range of substrates including damp surfaces.

Can Soudal sealants be used outdoors?

Yes. Roof, gutter, façade, and general exterior formulations across the Silicone Sealants and MS Sealants ranges are formulated with UV stabilisers to resist weathering and colour change over time. Check the specific product’s technical datasheet for exposure ratings before use on façades or roofing.

How long do sealants take to cure?

Most Soudal sealants form a surface skin within 10-30 minutes and reach full cure within 24 hours to 7 days, depending on bead depth, ambient temperature, and humidity. Full movement capability shouldn’t be relied on until the product has fully cured.

What sealant should I use for a bathroom?

A mould-resistant or neutral-cure silicone designed for wet areas.

Do I need a primer before applying sealant?

Most Soudal sealants don’t require a primer on standard substrates like glass, ceramic, aluminium, and painted timber. Porous, oily, or unusual substrates (some plastics, certain natural stones, automotive glass) may need a specific primer or activator, listed on the product’s technical datasheet. However, it is important to make sure that the surface is clean and dry before applying any sealant.
