Product Guide: Selleys No More Gaps Exterior vs. No More Gaps Timber Floors

Introduction

This guide compares two gap-filling products from Selleys: No More Gaps Exterior and No More Gaps Timber Floors. Both are acrylic-based gap sealants built for different jobs — one for outdoor exposure, the other for interior timber flooring. The datasheets referenced here are safety (GHS) documents, not full technical specifications. They confirm product identity, chemical composition, and safety requirements, but say nothing about cure time, movement accommodation, or substrate adhesion. This comparison sticks to facts drawn directly from those safety datasheets, clearly flagging where technical specifications are missing and calling out the key differences in formulation, packaging, and intended use. For specification-grade decisions, get the full technical datasheets or contact Selleys directly.

At-a-glance comparison

Weather/exposure rating

No More Gaps Exterior

The safety datasheet identifies this product as "No More Gaps Exterior" — a name that points clearly to outdoor applications. The SELLEYS_NO_MORE_GAPS_EXTERIOR-AUS_GHS.pdf confirms the material is non-combustible and should be stored out of direct sunlight, but it includes no weatherability data, UV resistance ratings, or temperature cycling specifications. For quantified performance data on rain resistance, freeze-thaw cycling, or UV degradation, consult the full technical datasheet or contact Selleys directly.

No More Gaps Timber Floors

The SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf identifies this product as a Timber Floors sealant, built for protected indoor environments. The datasheet carries no reference to outdoor exposure, weatherability, or UV resistance. Storage instructions match those of the Exterior variant (cool, dry, well-ventilated, away from sunlight), but these govern shelf stability rather than in-service durability.

Comparison: The Exterior formulation is built for external weather exposure. The Timber Floors variant is designed for the controlled conditions of interior spaces. Neither safety datasheet provides quantifiable exposure ratings. Users who need specific weatherability data — such as ASTM G154 UV hours or water immersion resistance — must source full technical datasheets or speak with Selleys directly.

Substrate

No More Gaps Timber Floors

The product name makes the application clear: timber floors. The SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf reinforces this with four colour variants — Baltic, Hardwood, Jarrah, and Walnut — matched to common Australian timber species. This confirms both the formulation and pigmentation are purpose-built for wood substrates. The safety datasheet does not specify adhesion test results, substrate preparation requirements, or compatibility with sealed versus unsealed timber; full technical documentation covers those details.

No More Gaps Exterior

The SELLEYS_NO_MORE_GAPS_EXTERIOR-AUS_GHS.pdf does not identify specific substrates. The Exterior designation points to compatibility with masonry, weatherboards, and other outdoor building materials, but the safety document includes no adhesion data, priming requirements, or lists of compatible and incompatible surfaces.

Comparison: The Timber Floors variant is purpose-built for wood flooring, with colour-matching options that deliver clean visible results. The Exterior product's substrate scope requires confirmation through technical documentation. For interior timber gaps, No More Gaps Timber Floors is the right tool. For external cladding, masonry, or mixed outdoor materials, No More Gaps Exterior is the product to reach for — verify substrate compatibility through the full technical datasheet.

UV/movement tolerance

Neither the SELLEYS_NO_MORE_GAPS_EXTERIOR-AUS_GHS.pdf nor the SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf documents UV stability, Shore A hardness, elongation-at-break, or joint movement accommodation (typically expressed as ±X%). Both datasheets confirm the materials are non-combustible and that residual material can burn after evaporation of the aqueous component — confirming an acrylic-water base — but physical flexibility and UV ageing performance are not covered in safety documentation.

Comparison: The Exterior product name points to UV resistance suited to outdoor service. The Timber Floors variant operates in interior conditions where UV exposure is indirect at most. Movement tolerance — critical for timber expansion and contraction as well as building movement — cannot be quantified from the supplied documents alone. Users requiring specific movement class ratings, such as ISO 11600 classifications, must source full technical datasheets from Selleys.

Application

No More Gaps Exterior

The SELLEYS_NO_MORE_GAPS_EXTERIOR-AUS_GHS.pdf provides safety-focused application guidance:

• Handling: Avoid eye contact and skin contact. Avoid inhalation of dust.
• PPE: Wear protective gloves and protective clothing including eye and face protection. Nitrile gloves are recommended for intermittent contact.
• Spill cleanup: Wipe small spills with an absorbent rag. For larger spills, cover with damp absorbent material and sweep or vacuum.

Application temperature, cure time, tooling window, paintability, and cleanup solvent are not specified in the safety document. Full technical datasheets carry these details.

No More Gaps Timber Floors

The SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf provides the same safety-based application guidance:

• Handling: Avoid eye contact and skin contact. Avoid inhalation of dust.
• PPE: Protective gloves (nitrile), clothing, and eye and face protection.
• Response: If on skin, wash with plenty of water and soap. If skin irritation or rash occurs, get medical advice and attention.

Like the Exterior variant, this datasheet does not cover working time, joint depth and width ratios, primer requirements, or post-application foot traffic timings.

Comparison: Safety protocols during application are identical for both products. The Timber Floors variant includes an additional precautionary statement (P302+P352, P333+P313) for skin contact response, reflecting labelling emphasis rather than a performance difference. Both products contain skin sensitisers (Category 1, H317), making glove use mandatory for both. Application-specific guidance — such as whether the Timber Floors product requires gap pre-cleaning or whether the Exterior product needs primer on porous substrates — is available through full technical documentation.

Pack sizes and colour options

No More Gaps Exterior

The SELLEYS_NO_MORE_GAPS_EXTERIOR-AUS_GHS.pdf confirms two pack sizes:

• 130g (product code 102092, barcode 9300697129819)
• 430g (product code 101904, barcode 9300697125668)

No colour variants are listed in the safety datasheet.

No More Gaps Timber Floors

The SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf lists a single size (380g) across four timber-matched colours:

• Baltic (codes 100473, 101906, N2190281-UNIT; barcode 9300697125484)
• Hardwood (codes 100472, 101905, N2190282-UNIT; barcode 9300697125477)
• Jarrah (codes 100474, 101907, N2190283-UNIT; barcode 9300697125491)
• Walnut (codes 100475, 101908; barcode 9300697125507)

Comparison: The Exterior product gives you a choice of pack size — 130g for smaller repairs, 430g for larger jobs. The Timber Floors variant is standardised at 380g but delivers strong colour matching for seamless integration with Australian timber species. Where the Exterior product has no specified colour variants and suits applications where the filler will be painted over, the Timber Floors colour range is built specifically for visible interior flooring repairs where colour matching matters.

Chemical composition and safety

No More Gaps Exterior

The SELLEYS_NO_MORE_GAPS_EXTERIOR-AUS_GHS.pdf lists three biocidal preservatives:

1. 1,2-Benzisothiazol-3(2H)-one (BIT) — CAS 2634-33-5, <0.05% w/w
2. 2-Methyl-2H-isothiazol-3-one (MIT) — CAS 2682-20-4, <0.05% w/w
3. 2-Octyl-2H-isothiazol-3-one (OIT) — CAS 26530-20-1, <0.05% w/w

This three-preservative system includes OIT, widely used in exterior coatings for mould and algae resistance — an important advantage in exposed outdoor conditions.

No More Gaps Timber Floors

The SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf lists two preservatives:

1. 1,2-Benzisothiazol-3(2H)-one (BIT) — CAS 2634-33-5, <0.05% w/w
2. 2-Methyl-1,2-benzisothiazol-3(2H)-one (MBIT) — CAS 2527-66-4, <0.05% w/w

Both products share BIT but differ in secondary preservatives. The Timber Floors formulation drops OIT — the broad-spectrum exterior fungicide — in favour of MBIT, which suits the lower microbial challenge of interior environments.

Comparison: Both formulations carry the same H317 skin sensitisation hazard and require identical PPE: nitrile gloves and eye protection. The Exterior product's three-preservative system, including OIT, delivers stronger microbiological protection for damp outdoor environments. The Timber Floors preservative system is appropriate for climate-controlled interior spaces where extreme UV, water immersion, and heavy fungal growth are not factors. Anyone with isothiazolinone sensitivities should avoid both products. Neither datasheet discloses a preservative-free alternative — contact Selleys directly for guidance.

When to choose No More Gaps Exterior

Choose this product when:

1. Filling gaps in outdoor building elements — The product name and OIT-inclusive preservative system (per SELLEYS_NO_MORE_GAPS_EXTERIOR-AUS_GHS.pdf) point to strong performance on exterior cladding, window perimeters, masonry joints, and other weather-exposed applications. Confirm full weatherability data through the technical datasheet before specification-grade use.

2. Pack size flexibility matters — The 130g cartridge handles small repairs and touch-ups. The 430g cartridge suits larger projects. This choice is not available with the 380g-only Timber Floors variant.

3. The finish will be painted over — Without specified colour matching, this product suits applications where the gap filler goes under paint or where colour matching to the substrate is not a requirement.

When to choose No More Gaps Timber Floors

Choose this product when:

1. Filling gaps in timber flooring — The product name, purpose-built formulation, and four timber-species colour options (Baltic, Hardwood, Jarrah, Walnut per SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf) make this the clear choice for floorboard gaps, skirting joints, and timber stair repairs.

2. Invisible repairs are the goal — Four colour options deliver near-invisible results when matched to timber species. No post-application staining or painting required.

3. The environment is indoor and climate-controlled — The targeted preservative system (BIT and MBIT, without the exterior-focused OIT) is built for interior spaces where extreme UV, water immersion, and heavy fungal growth are not factors.

Summary

No More Gaps Exterior and No More Gaps Timber Floors are both acrylic gap sealants from Selleys. Both carry identical skin sensitisation hazards (H317) and handling requirements (nitrile gloves, eye protection). The supplied safety datasheets confirm that the Exterior variant uses a three-preservative system (BIT, MIT, OIT) built for outdoor microbial challenge, and is available in 130g and 430g packs. The Timber Floors variant uses a two-preservative blend (BIT, MBIT), comes in a single 380g size, and offers four timber-matched colours — Baltic, Hardwood, Jarrah, and Walnut — for interior flooring applications.

The practical trade-off is straightforward: the Exterior product's formulation and name point to weather durability for outdoor gaps, but the supplied datasheet includes no UV resistance, movement tolerance, or substrate compatibility data. The Timber Floors product is built for interior wood flooring with colour matching, and is not intended for external exposure. Neither datasheet provides the technical performance data — cure time, elongation, adhesion strength — needed for specification-grade project selection. Get the full technical datasheets or contact Selleys directly to confirm suitability for your specific gap width, substrate, and exposure conditions.

Related Products & Brand Context

No More Gaps Exterior sits within Selleys' No More Gaps product range, which groups together a family of purpose-built gap fillers designed for different surfaces and environments. The closest sibling in the range is No More Gaps Timber Floors, and comparing the two illustrates how Selleys has engineered each product for a specific job rather than offering a single all-purpose filler. No More Gaps Exterior targets outdoor surfaces — weatherboards, door frames, tongue-and-groove cladding, and other exterior gaps exposed to the elements — while No More Gaps Timber Floors is formulated for interior timber flooring, benchtops, skirting boards, and architraves, and notably contains real wood fibre so the cured filler can be stained to blend with surrounding timber.

Selleys is an Australian-focused manufacturer best known for adhesives, sealants, and surface preparation products. No More Gaps Exterior fits their broader range of weather-resistant sealants, positioned as a flexible, water-based option suited to the UV exposure and temperature swings common in Australian conditions. Its polymer system and titanium compound formulation give it the flexibility and weather resistance expected of an exterior-grade product, distinguishing it clearly from interior-only fillers in the same No More Gaps line.

Within the Home & Garden > Caulking & Gap Fillers category, No More Gaps Exterior occupies the exterior/weatherproof segment. The key differentiator from No More Gaps Timber Floors is environmental suitability: the Exterior variant is built to resist weathering and UV damage without cracking or shrinking, whereas the Timber Floors product prioritises a timber-matched aesthetic finish for indoor use. Buyers choosing between them should start with the location — outdoors or indoors — rather than the surface material alone.

Someone using No More Gaps Exterior on weatherboards or door frames is likely to also need a caulking gun for precise application, a surface cleaner or degreaser to prepare the substrate before filling, and potentially an exterior primer or paint to finish and protect the filled area. These are complementary products typically stocked alongside gap fillers in the caulking and sealants aisle rather than part of the No More Gaps range itself.
