Whether you're completing new plasterboard work or managing repairs, we can help you explore options suited to the surfaces and conditions involved.

Choosing Between Joint Sealants and Gap Fillers

Although joint sealants and gap fillers are often discussed together, their applications can differ. Sealants are commonly selected for joints where a continuous seal is required, while fillers may be used to close suitable openings or prepare uneven areas for subsequent work.

The right choice depends on the width and location of the opening, the material being treated, and whether movement is expected. Our range of sealants and fillers gives you options to consider across these common applications.

Sealing Joints and Finishing Gaps

On building and fitout projects, joint sealants can be used around compatible junctions, penetrations, and transitions between materials. Some situations call for flexibility to accommodate movement, while others require a specified installation system or performance rating. Before applying joint sealants, check the substrate, preparation requirements, and the manufacturer's suitability guidance.

Gap fillers are often selected for suitable cracks, openings, and finishing work where a neat, even result is needed. Different gap fillers offer different application and curing properties, so consider whether the area will be painted, exposed to moisture, or subject to movement. Choosing between sealants and fillers based on the actual application helps avoid mismatched materials.

Practical Considerations for Trade and DIY Work

For contractors, choosing joint sealants involves more than selecting a convenient packaging format. Coverage, working time, tooling, cure conditions, and compatibility with adjoining materials can all affect the job. Our gap fillers can support various finishing needs, while appropriately specified joint sealants help address joint sealing requirements throughout an installation.

DIY renovators may be tackling smaller tasks such as sealing a junction or preparing an area for decoration. When comparing gap fillers, start with the intended surface and required finish. Our team can help explain the differences among sealants and fillers, including when a specialised material or manufacturer-approved system is needed.

Matching Materials to the Project

Not all joint sealants or gap fillers suit every substrate or environment. If your project involves wet areas, fire-rated or acoustic assemblies, or other performance requirements, confirm that the selected material is specifically approved for that purpose. The application details matter just as much as the product category, particularly where compliance or ongoing movement is involved.
