Product Guide: Selleys No More Gaps Comparison

Introduction

Choosing the right gap filler gets the job done properly the first time. This guide compares three products from Selleys' No More Gaps range: the Bathroom & Kitchen formula, the Interior Fast Dry, and the Interior Multipurpose. All three share the same skin-sensitisation hazard profile, but each is built for a specific job — they differ in application environment, available pack sizes, and chemical preservative systems. This comparison draws directly from the manufacturers' Safety Data Sheets. These documents focus on safety information rather than performance specifications, so data on drying times, paintability, movement tolerance, and gap-filling capacity aren't available in the supplied datasheets. For those performance details, consult the technical datasheets.

Best-fit room

Bathroom & Kitchen

The Bathroom & Kitchen SDS explicitly states its recommended use as "Flexible sealant for bathroom applications." That designation tells you this formula is engineered for high-moisture, high-humidity environments — exactly the conditions found in bathrooms and kitchens.

Interior Fast Dry

The Interior Fast Dry SDS recommends this product as a "Gap sealant" for interior use, with no specific room designation. The absence of bathroom-specific or moisture-environment claims sets it apart from the Bathroom & Kitchen formula — this one is built for general interior work across a wide range of gaps.

Interior Multipurpose

The Multipurpose SDS specifies "Flexible gap sealant for interior/exterior use," making it the only product in this comparison with documented approval for outdoor applications. It works indoors too, but the exterior capability gives it the broadest scope of the three.

Key trade-off: The Bathroom & Kitchen formula targets wet environments with precision. The Multipurpose extends to exterior use. The Interior Fast Dry covers general interior work where application-specific claims aren't required.

Chemical composition and preservative systems

The preservative system in each formula is worth understanding — it's how you match the right product to the right environment, and each blend is engineered to protect the sealant against microbial degradation.

Bathroom & Kitchen preservative blend

The Bathroom & Kitchen SDS composition table lists three isothiazolone preservatives: 1,2-Benzisothiazol-3(2H)-one (BIT) at <0.05%, 2-Methyl-2H-isothiazol-3-one (MIT) at <0.05%, and 2-Octyl-2H-isothiazol-3-one (OIT) at <0.5%. The OIT at a higher concentration ceiling is what separates this formula from the Interior Fast Dry — a deliberate engineering choice for wet-area performance.

Interior Fast Dry preservative blend

The Interior Fast Dry SDS lists two preservatives: 5-Chloro-2-methyl-4-isothiazolin-3-one (CMIT) at <0.05% and MIT at <0.05%. This is the most streamlined preservative system of the three, and the only one without OIT. For standard interior applications, this focused blend does the job.

Interior Multipurpose preservative blend

The Multipurpose SDS lists four preservatives: BIT (<0.05%), CMIT (<0.05%), MIT (<0.05%), and OIT (<0.05%). That's the broadest preservative coverage of the three products. Worth noting: OIT appears at a lower maximum concentration (<0.05%) than in the Bathroom & Kitchen formula (<0.5%), despite both products containing it.

Key trade-off: The Bathroom & Kitchen formula carries the highest OIT concentration ceiling — up to 0.5% versus 0.05% in the Multipurpose. That higher loading reflects the mould and mildew resistance required in wet environments. The Interior Fast Dry runs a two-preservative system suited to dry interior conditions. The Multipurpose uses all four preservatives for broader protection across varied environments.

Size availability and packaging

Bathroom & Kitchen

The Bathroom & Kitchen SDS product variants table documents two sizes: 130g and 410g cartridges. The 130g option is the smallest format across all three products — a practical choice for minor repairs where you don't want leftover material.

Interior Fast Dry and Multipurpose

Both the Interior Fast Dry and Interior Multipurpose come in 475g format, as confirmed by their respective product names and SDS documents. Neither datasheet lists alternative sizes. At 475g, these cartridges are approximately 16% larger than the Bathroom & Kitchen's maximum 410g size — suited to moderate and large projects that need more material.

Key trade-off: Only the Bathroom & Kitchen offers the 130g tube for targeted repair work. The Interior Fast Dry and Multipurpose both come in the larger 475g format, making them the better fit for bigger jobs.

Interior versus exterior suitability

Bathroom & Kitchen and Interior Fast Dry

The Bathroom & Kitchen SDS doesn't explicitly state exterior suitability. Its recommended use focuses on bathroom applications — typically interior environments. The Interior Fast Dry SDS specifies "Gap sealant" for interior work, with no exterior claims in the supplied documentation.

Interior Multipurpose

The Multipurpose SDS explicitly states "Flexible gap sealant for interior/exterior use." This is the only product in this comparison with a documented outdoor application claim. When the job takes you outside, this is the one to reach for.

Key trade-off: For outdoor installations or surfaces exposed to weather, the Multipurpose is the clear choice based on the supplied datasheets. The Bathroom & Kitchen and Interior Fast Dry lack exterior-use claims in the supplied documentation — use them where they're engineered to perform.

Drying time, paintability, movement tolerance, and gap size

The supplied Safety Data Sheets for all three products don't contain specifications for drying time, paintability, movement tolerance, or maximum gap-filling capacity. Safety Data Sheets are regulatory documents built for hazard communication, chemical composition, and safe handling — not application performance.

The Bathroom & Kitchen SDS describes the product as a "Flexible sealant," and the Multipurpose SDS uses "Flexible gap sealant." Neither document quantifies movement capability in percentage or millimetre terms. The Interior Fast Dry SDS includes no flexibility claims in its recommended use statement.

For cure speed, overcoatability, joint movement accommodation, or gap width limits, consult the technical datasheets (TDS) or product application guides. Those documents contain the performance specifications you need to plan the job properly. The supplied materials don't include them.

When to choose No More Gaps Bathroom & Kitchen

Choose this product when:

• Working in wet environments: The SDS positions this as a bathroom-focused sealant. Its higher OIT preservative ceiling — up to 0.5% versus 0.05% in the Multipurpose — delivers better mould and mildew resistance in moisture-prone areas.
• Small repair jobs need a precise solution: The 130g tube is the only small format available across the three products. It reduces waste and gives you the right amount of material for minor gap-sealing tasks.
• Kitchen or bathroom installations are on the schedule: The product name and recommended use directly target these high-humidity rooms. The formulation aligns with the moisture exposure and substrate types — tile, porcelain, laminate — found in these spaces.

When to choose No More Gaps Interior Fast Dry

Choose this product when:

• General interior gap sealing is the task: The SDS designates this as a "Gap sealant" without application-specific restrictions. It's a reliable choice for interior trim, skirting, architraves, and general gaps where a specialised formula isn't needed.
• A focused preservative profile suits the application: With CMIT and MIT as its two preservatives — versus three or four in the other products — this formula runs a targeted biocide system. For users who require a specific isothiazolone profile, this is the product to reach for.
• The 475g cartridge fits the scope of work: Available in a single 475g format, this product suits moderate to large interior projects where a small-tube option isn't required.

When to choose No More Gaps Interior Multipurpose

Choose this product when:

• Exterior application is part of the job: The SDS explicitly states "interior/exterior use." This is the only product in the comparison with a documented outdoor claim. For window frames, external trim, or weatherboard gaps exposed to the elements, this is the one the safety datasheet backs.
• Broad-spectrum preservative protection is the priority: The Multipurpose uses all four isothiazolone preservatives — BIT, CMIT, MIT, and OIT — giving it the widest biocide coverage across fungal and bacterial species. Individual concentrations are lower than the Bathroom & Kitchen's OIT loading, but the full-spectrum approach suits varied environments.
• One product needs to cover multiple substrates and conditions: The "Multipurpose" designation and interior/exterior scope reflect a formula built for versatility. One product across many applications keeps professionals and DIYers from stocking multiple specialised products.

Summary

All three Selleys No More Gaps products share identical skin-sensitisation hazard classifications and similar first-aid protocols, but each is purpose-built for a specific set of conditions. The Bathroom & Kitchen variant is engineered for wet environments, carrying the highest OIT preservative concentration and the only 130g small-tube option. The Interior Fast Dry handles general interior gap sealing with a two-preservative system in a 475g format. The Interior Multipurpose extends to exterior use with a four-preservative blend, also in a 475g cartridge.

The decision comes down to environment. Bathroom & Kitchen for wet interiors where mould resistance matters. Interior Fast Dry for dry interior applications where a focused formula is enough. Multipurpose when outdoor exposure is a factor and you need one product across a range of conditions.

The supplied Safety Data Sheets don't contain performance specifications such as drying time, paintability, or movement tolerance. Consult the technical datasheets for those application-critical details before you start the job.

Related Products & Brand Context

The three products covered in this guide — No More Gaps Bathroom & Kitchen, No More Gaps Interior Fast Dry (475g), and No More Gaps Interior Multipurpose Gap Filler (475g) — are all siblings within Selleys' No More Gaps range, sitting in the Home & Garden > Sealants & Fillers category. Selleys is an Australian brand with a long-standing presence in the putty, filler, and sealant space, and the No More Gaps line represents their mainstream gap-filling offering aimed at both home renovators and tradespeople.

Within the range, each product is tuned to a distinct environment. No More Gaps Bathroom & Kitchen is formulated for wet and humid rooms, offering water and mould resistance — making it the appropriate choice around sinks, taps, and tiles where moisture exposure is ongoing. No More Gaps Interior Fast Dry targets general dry interior gaps where a quicker return-to-paint time is the priority, suiting rooms like hallways, living areas, or bedrooms that don't face moisture challenges. No More Gaps Interior Multipurpose Gap Filler occupies a broader middle ground, designed to handle a variety of interior gap-filling tasks across both residential and commercial settings — useful when a single product needs to serve multiple rooms or applications in one job.

The category position for all three is flexible gap fillers, which distinguishes them from rigid fillers or setting-type compounds. Because these products are paintable once cured, buyers working with them will typically also need surface preparation supplies (such as a primer or undercoat), appropriate applicator tools (a caulking gun for cartridge formats, or a spatula for smoothing), and painter's tape to achieve clean sealant lines. Cleanup tools and solvent wipes may also be relevant depending on the specific formulation.

When choosing between the three, the key differentiators are moisture exposure (Bathroom & Kitchen for wet areas), drying speed (Interior Fast Dry for quicker turnaround), and breadth of use (Multipurpose for varied interior projects). All three carry the Selleys No More Gaps name and share the same core brand commitment to flexible, paintable gap filling.
