Work Safely: This Product Is Classified WARNING Selleys No More Cracks Large Cracks & Holes is hazardous according to the criteria of Safe Work Australia GHS 7. The signal word is Warning. It is classified as NON-Dangerous Goods. Hazard statement: CodeStatementWhat This MeansH317May cause an allergic skin reactionSkin Sensitisation Category 1. Repeated or prolonged skin contact may lead to allergic contact dermatitis. Effects may be delayed — you may not notice a reaction immediately. The product may also be an eye irritant — exposure to dust may cause discomfort due to particulate nature and may cause physical irritation to the eyes. It may be an irritant to mucous membranes and respiratory tract. Key precautionary statements:

P102: Keep out of reach of children P103: Read carefully and follow all instructions P261: Avoid breathing dust, fume, gas, mist, vapours, or spray P272: Contaminated work clothing should not be allowed out of the workplace P280: Wear protective gloves/protective clothing including eye/face protection and suitable respirator

Protect Yourself with the Required PPE The required personal protection equipment is: SAFETY SHOES, OVERALLS, GLOVES, SAFETY GLASSES. Additionally, P280 specifies a suitable respirator — particularly relevant during sanding operations when fine dust is generated. Gloves: Nitrile rubber gloves should be suitable for intermittent contact. Due to variations in glove construction and local conditions, make a final assessment based on your situation. This is particularly important given the H317 skin sensitisation hazard — bare-skin contact should be avoided. Repeated or prolonged contact may lead to allergic contact dermatitis, and effects may be delayed. Safety glasses: The product may be an eye irritant, particularly from dust generated during sanding. Overalls and safety shoes: Full body coverage minimises skin contact with the skin sensitiser. Contaminated work clothing should not be allowed out of the workplace. Wash contaminated clothing and other protective equipment before storing or re-using. Respirator: P280 specifies a suitable respirator. This is especially important during sanding when fine dust becomes airborne. The product may irritate mucous membranes and respiratory tract. Engineering: Natural ventilation should be adequate under normal use conditions. Hygiene: Always wash hands before smoking, eating, drinking, or using the toilet. Do not eat, drink, or smoke when using this product. Keep away from food, drink, and animal feeding stuffs. Avoid contact with clothing. Avoid eye contact and skin contact. Avoid inhalation of dust. Ensure that eyewash stations and safety showers are close to the workstation location.

Prepare the Surface Ensure the surface to be filled is clean and dry with no loose or powdery material. This is the critical first step. Any contamination, moisture, or unstable substrate material will compromise adhesion. Exterior surfaces: It is recommended that exterior surfaces are primed before filling. This improves adhesion and helps the repair integrate with the surrounding surface. Note on surface types: The product has superior adhesion to plaster, mortar, concrete, timber, and primed metal. It is also suitable for brick and stone. For primed metal, ensure the primer is sound and well-adhered before filling.

Apply the Filler Use a filling blade or scraper to firmly press the filler in and scrape off excess to minimise sanding. Press firmly during application to ensure complete contact with all surfaces of the crack or hole. Scraping off excess flush with the surrounding surface reduces sanding effort once the repair is dry. Allow to dry for 2–3 hours, depending on humidity. This drying time applies to applications of less than 2mm. For thicker applications up to 6mm, allow 24 hours before sanding or painting.

Build Depth with 6mm Layers For deeper repairs, apply in 6mm layers, allowing each layer to dry before applying the next. This is the single most important technique for successful deep repairs. The 6mm maximum applies to each individual layer — this allows proper drying throughout the full depth of each application. Applying thicker layers risks incomplete drying through the full depth, which can lead to cracking or soft spots. How to calculate layers: Measure hole depth and divide by 6mm. A 12mm hole needs 2 layers. An 18mm hole needs 3 layers. A 30mm hole needs 5 layers. Allow each layer to dry before applying the next. Drying between layers: Applications up to 6mm require 24 hours for sand/paint readiness. Allow each 6mm layer to dry before applying the next, with drying time dependent on humidity and conditions. Overfill the final layer only slightly to minimise sanding. This is the manufacturer's tip for achieving a flush finish — a slight overfill is sanded back to perfectly level rather than trying to fill exactly flush, which risks leaving low spots.

Allow Proper Drying Time Selleys No More Cracks Large Cracks & Holes dries by water evaporation. Drying time depends on application thickness and humidity. ThicknessDrying TimeLess than 2mm2–3 hours (depending on humidity)Up to 6mm24 hours Note: Drying time for 6mm is listed as "+16 hours" in some documentation and "24 hours" in other documentation. Both are provided for reference — allow adequate time and verify the layer is fully dry before sanding, painting, or applying the next layer. Do not use below 5°C. Cold conditions slow water evaporation significantly.

Sand and Finish Once the repair is fully dry, sand back with fine sandpaper. The product is specifically formulated to be easy to sand, delivering a smooth finish ready for painting. Painting sequence for best results:

Sand the repair flush with the surrounding surface using fine sandpaper Apply an undercoat before your top coat of paint for best results Apply your top coat

Exterior repairs: Protect exterior applications from rain until painted over. The repair must be fully dry and painted to achieve full weather protection.

Clean Up Uncured product: Remove with water. Clean tools with water before filler dries — once cured, water will not dissolve it. Cured product: Remove by sanding and scraping. Spill response (from SDS):

Small spills: Wear protective equipment. Wipe up with absorbent (clean rag or paper towels). Collect and seal in properly labelled containers. Large spills: Clear area of unprotected personnel. Slippery when spilt. Wear protective equipment. Cover with damp absorbent (sand or soil). Sweep or vacuum — avoid generating dust. If contamination of waterways occurs, advise local emergency services.

Disposal: Dispose of contents/container in accordance with local, regional, national, and international regulations. If possible, material and container should be recycled. Avoid contaminating waterways.

Know the Limitations

Do not use below 5°C — applies to both storage and application Not for permanent water immersion — the product is water-based and not designed for submerged conditions Not suitable for exterior timber likely to absorb excessive amounts of water — waterlogged timber will compromise adhesion Where movement occurs, use Selleys No More Gaps — this filler is designed for static repairs; joints or cracks subject to ongoing movement require a flexible sealant

Tips for Best Results These tips come directly from the manufacturer's guidance: For deeper holes, fill in 6mm layers. Allow each layer to dry before applying the next. Patience with layering delivers a permanent repair; rushing with thick layers leads to cracking. Overfill the final layer only slightly to minimise sanding. A slight overfill sanded flush gives a better result than trying to fill exactly level. Prime exterior surfaces before filling. This improves adhesion between filler and substrate on outdoor repairs. Protect exterior applications from rain until painted over. The uncured filler is water-based and will wash out if exposed to rain before drying. For best results, apply an undercoat before your top coat of paint. The repair area may have different absorption characteristics compared to the surrounding surface. An undercoat creates a uniform base for the final paint coat. Press filler firmly into the surface. Firm application with a filling blade or scraper ensures full contact with the crack or hole surfaces and eliminates voids that could compromise the repair. Scrape off excess to minimise sanding. Good technique during application reduces finishing time. Clean tools with water before filler dries. The water-based formulation cleans up easily while wet — but once cured, removal requires sanding and scraping.

Troubleshoot Common Problems Problem: Repair cracks after drying The most likely cause is layer thickness exceeding 6mm. Deeper repairs must be built up in 6mm layers, allowing each to dry before the next. Remove cracked material, allow to dry, and restart with proper 6mm layers. Problem: Filler won't adhere to surface Ensure the surface is clean and dry with no loose or powdery material. For exterior surfaces, prime before filling. For primed metal, ensure the primer is sound and well-adhered. Problem: Slow drying Drying depends on humidity and temperature. At less than 2mm thickness, expect 2–3 hours. At up to 6mm, allow 24 hours. Do not use below 5°C — cold conditions slow drying significantly. Problem: Repair not flush after drying Some shrinkage is normal, though the product features minimal shrinkage. If the repair sits below the surface, apply an additional thin layer, allow to dry, and sand flush. Overfilling the final layer slightly (as the manufacturer recommends) helps avoid this. Problem: Filler difficult to remove from tools Clean tools with water immediately after use. Once the product cures, it can only be removed by sanding and scraping — prevention is much easier than removal. Problem: Repair cracks return in the same location If the underlying crack is caused by structural movement, this filler will not accommodate ongoing movement. Where movement occurs, use Selleys No More Gaps, which offers the flexibility needed for dynamic joints and cracks. Problem: Filler washing out on exterior repairs Exterior applications must be protected from rain until fully dry and painted over. The manufacturer also recommends priming exterior surfaces before filling for best adhesion.
