It contains real wood fibre, not just pigments, which gives it a genuine timber-matched finish that sits naturally with your floor rather than standing out against it. Each variant comes in a 380g cartridge for standard caulking gun application (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). This is a gap sealant, not a structural adhesive (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Its job is to close visual gaps, stop debris working its way into timber floor joints, and deliver a clean finish across expansion gaps and perimeter transitions. That distinction matters because it defines where the product works well: a flexible, colour-matched seal in non-load-bearing applications where timber naturally expands and contracts through the seasons. ## Chemistry and composition Selleys No More Gaps Timber Floors is an aqueous acrylic sealant with built-in antimicrobial protection. Two biocides form the preservative system: 1,2-Benzisothiazol-3(2H)-one (BIT) at less than 0.05% w/w and 2-Methyl-1,2-benzisothiazol-3(2H)-one (MBIT) at less than 0.05% w/w (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). These isothiazolinone preservatives protect the water-based formulation from microbial degradation in storage and after application, keeping the product performing in the moisture-variable environment of a timber floor. The rest of the formulation uses non-hazardous ingredients: acrylic polymers, fillers, pigments, and water (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). The pigment systems are calibrated to replicate the visual character of Baltic pine, hardwood species, Jarrah, and Walnut timber, so the cured sealant blends with the surrounding floor rather than drawing attention to itself. Because water is the carrier, the product cures through moisture evaporation rather than chemical cross-linking — a fact that shapes both how you apply it and how it performs over time. ## Available variants and product codes Four colour-matched variants cover the most common Australian timber species, each available under multiple product codes for different distribution channels. Baltic 380g (product codes 100473, 101906, and N2190281-UNIT; barcode 9300697125484) is formulated to match light-toned Baltic pine and similar pale timber species (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Hardwood 380g (product codes 100472, 101905, and N2190282-UNIT; barcode 9300697125477) is calibrated to medium-brown hardwood tones typical of Australian native species (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Jarrah 380g (product codes 100474, 101907, and N2190283-UNIT; barcode 9300697125491) is matched to the distinctive reddish-brown hue of Jarrah timber (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Walnut 380g (product codes 100475 and 101908; barcode 9300697125507) is designed to complement dark walnut and similar deep-toned timber finishes (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Multiple product codes reflect different packaging or distribution variants of the same formulation. Performance is identical within each colour category, which keeps specification straightforward across projects of any scale. ## Key features and performance characteristics The timber-matched pigmentation system is what sets this product apart from generic gap fillers. Rather than leaving a white or grey line across your floor, the sealant blends into the surrounding timber — a meaningful difference in high-visibility residential spaces and commercial installations where floor appearance affects perceived quality. As an acrylic sealant, the cured product stays flexible. Timber expands as it absorbs moisture and contracts when conditions dry out. A rigid filler cracks under that cyclic stress, opening pathways for dirt and requiring reapplication. The flexible acrylic matrix in Selleys No More Gaps Timber Floors holds its seal through those movement cycles without the maintenance headache. One note on fire classification: the wet, uncured product contains significant water content, but the cured residue may be combustible. Confirm the applicable fire classification against the current Safety Data Sheet before specifying the product in environments where fire classification is a regulatory requirement. Coverage should be verified against the official Technical Data Sheet. A single 380g cartridge is calibrated for typical residential room installations, where one cartridge commonly handles a standard-sized room's perimeter gaps in a single pass. ## Recommended applications Selleys No More Gaps Timber Floors is purpose-built for timber floor installations where gaps need sealing for aesthetic or functional reasons. It works well across these primary applications. Perimeter expansion gaps: the joint between timber flooring and wall skirting boards typically calls for a 10–15mm expansion gap to accommodate seasonal floor movement. This sealant fills that gap cleanly while the floor moves beneath it. Floorboard joints: gaps between individual timber boards, whether from shrinkage or original installation, get filled to stop debris accumulating and to restore a uniform floor appearance. Transition joints: at the interface between timber flooring and other floor finishes such as tile, carpet, or vinyl, a flexible seal prevents debris migration while handling differential movement between materials. Penetration sealing: gaps around pipe penetrations, floor vents, and built-in fixtures where timber flooring has been cut to accommodate these elements get a neat, colour-matched finish. This product is not suited to structural gap filling in load-bearing applications, exterior exposed joints subject to UV degradation, or gaps wider than approximately 20mm where sealant mass becomes too thick to cure evenly. For gaps beyond that, use backing rod or foam to reduce effective gap depth before applying sealant. ## Surface preparation and application technique Surface preparation is where lasting results begin. Gaps must be clean, dry, and free from loose debris, oil, wax, or polish residues that would block adhesion. On existing floors, vacuum gaps thoroughly and wipe surfaces with methylated spirits to cut through floor polish or wax contamination. New installations should be swept clean and left to reach equilibrium moisture content before gap filling begins. Load the 380g cartridge into a standard caulking gun and cut the nozzle at a 45-degree angle to achieve the bead size you need. Match the nozzle cut diameter to the gap width for accurate material placement. Apply steady, continuous pressure to the trigger while drawing the nozzle along the gap at a consistent speed. Aim to deposit a bead that slightly overfills the gap, producing a convex surface ready for tooling. Immediately after application, tool the bead with a wet finger, shaped plastic tool, or damp sponge. This compresses the sealant into the gap, creates a smooth finish, removes excess material, eliminates voids, and locks adhesion to both gap faces. Work in sections short enough to tool before the surface begins to skin — skin time is 30 minutes under normal conditions — and keep your tooling implements ready before you apply each section. Curing moves from the surface inward as moisture evaporates. Shallow gaps under 5mm deep cure within 24 hours in normal conditions. Deeper gaps need several days to cure completely. Keep foot traffic off freshly applied sealant for at least 2 hours to avoid tracking and disturbance. ## Hazards and safety precautions Selleys No More Gaps Timber Floors is classified as hazardous under Safe Work Australia GHS 7 criteria, specifically as a Skin Sensitizer Category 1 with hazard statement H317: "May cause an allergic skin reaction" (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). The BIT and MBIT preservatives are responsible for this classification. The signal word is Warning (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Follow these precautionary measures every time: avoid breathing dust, fume, gas, mist, vapours, or spray (P261), and keep contaminated work clothing out of non-work areas (P272) (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). These requirements carry particular weight during large-scale commercial installations where multiple applicators work simultaneously in enclosed spaces. Wear protective gloves, protective clothing, and eye/face protection (P280) (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Nitrile rubber gloves are recommended for intermittent contact, though make your final selection based on specific glove construction and your working conditions (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Wash hands before eating, drinking, smoking, or using toilet facilities (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). If skin contact occurs, wash thoroughly with plenty of water and soap (P302+P352) (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). If skin irritation or a rash develops, get medical advice (P333+P313) (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Remove contaminated clothing and wash it before wearing again (P362+P364) (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Symptoms from sensitizer exposure can be delayed, so monitor for reactions in the hours following exposure (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Keep out of reach of children (P102) and read all instructions before use (P103) (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). In a poisoning emergency, contact the Poisons Information Centre at 131 126 (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). The product is not classified as Dangerous Goods under Australian transport regulations (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf), which keeps logistics simple for contractors managing material delivery to job sites. ## Storage and handling Store cartridges in a cool, dry location away from direct sunlight and heat sources. Elevated temperatures alter sealant consistency and accelerate preservative breakdown, cutting shelf life short. As an aqueous formulation, this product is vulnerable to freeze-thaw damage — never store it where temperatures drop to freezing, as ice crystal formation permanently disrupts the polymer matrix. After use, seal partially used cartridges immediately. Clean the nozzle, reinstall the cap, or push a large nail into the nozzle to block air exposure. Even with proper sealing, a partially used cartridge has a shorter shelf life than an unopened one, as moisture evaporation continues at the material surface. Spilled sealant creates a slip hazard on floor surfaces (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Clean spills immediately using damp absorbent material (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). For small spills, clean rags or paper towels work well — collect the waste and seal it in properly labelled containers for disposal (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Large spills call for covering with damp absorbent material such as sand or soil, then sweeping or vacuuming while keeping dust generation to a minimum (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Dispose of contents and containers in line with local, state, and national regulations (P501) (SELLEYS_NO_MORE_GAPS_TIMBER_FLOORS-AUS_GHS.pdf). Empty cartridges with fully cured material typically qualify as general waste, but confirm with your local waste management authority as regulations vary by jurisdiction. ## Troubleshooting and best practices **Colour mismatch with flooring:** Timber shows natural colour variation even within a single species. Always test the sealant in an inconspicuous area first to confirm colour compatibility. If none of the four standard colours align closely enough with your floor, consider using timber dust mixed with an appropriate adhesive to create a custom-matched filler, though that approach requires additional expertise and preparation. **Sealant shrinkage in deep gaps:** Gaps deeper than 10mm can show surface depression as moisture evaporates from the sealant mass during curing. Apply sealant in multiple passes, letting each layer cure before adding the next. Alternatively, insert closed-cell foam backing rod to reduce effective gap depth before applying sealant. **Adhesion loss at gap edges:** This almost always points to inadequate surface preparation. Oil, wax, and polish residues are the most common culprits in timber floor applications. Remove the failed sealant, clean the gap thoroughly with methylated spirits, allow surfaces to dry completely, and reapply. Where timber has been heavily treated with penetrating oils, adhesion may remain compromised regardless of preparation — in those cases, mechanical gap filling methods deliver more reliable results. **Premature surface skinning:** High ambient temperatures or low humidity speed up surface curing and reduce working time for tooling. Work in shorter sections and have your tooling implements ready before applying each run. Lightly misting the bead with water immediately before tooling can extend working time marginally, but avoid over-wetting — excess water dilutes the sealant and affects performance. **Cleanup taking longer than expected:** This usually means tooling was delayed too long, or adjacent surfaces weren't protected before application. Remove uncured excess with a damp cloth immediately after tooling. Once cured, excess must be scraped off mechanically, which risks damaging the floor finish. Applying painter's tape to timber surfaces adjacent to gaps before sealant application gives you clean edges and eliminates cleanup concerns — the extra time upfront pays off in a better finished result. Work in well-ventilated areas to support moisture evaporation and speed curing, particularly in enclosed spaces or during humid conditions when cure times extend. Good ventilation also reduces potential vapour exposure, though the aqueous formulation produces minimal volatile emissions compared to solvent-based sealants. ## References - Source PDF:

Within the Selleys range, this product sits inside the **Gap Fillers & Sealants** segment of the broader Home & Garden category, specifically under the putty and fillers grouping. Its dedicated timber flooring focus distinguishes it from general-purpose gap fillers in the same family — where a standard gap filler might suit walls or skirting boards, No More Gaps Timber Floors is engineered for the particular demands of moving timber substrates, offering 25% movement capability and an elongation at break exceeding 500%. Within the product itself, differentiation comes from four colour variants — **Jarrah**, **Hardwood**, **Walnut**, and **Baltic** — each matched to specific Australian and imported timber species. This means buyers choosing between variants are essentially selecting a sibling SKU rather than a different product, with Jarrah suited to timbers like River Red Gum and Karri, Hardwood covering species such as Black Butt and Spotted Gum, Walnut targeting Ironbark, Teak, and engineered floors, and Baltic addressing Pine, Myrtle, and Alpine Ash. All variants share identical technical specifications and are supplied in 380 g cartridges. From a use-case adjacency perspective, anyone applying No More Gaps Timber Floors is likely working on a flooring installation or repair project. That typically means they will also need a compatible floor finish or stain — the product is explicitly stainable and sandable, so it is designed to sit beneath or alongside floor coating products. A standard cartridge gun is required to dispense the 380 g cartridge format, making applicator tools a natural companion purchase. Surface preparation materials such as a vacuum or compressed air for clearing debris from gaps before application would also commonly be needed. The graph context does not name additional Selleys sibling products by title beyond this product, so no further specific product-to-product comparisons can be drawn from the available data.
