Work Safely: This Product Is Classified WARNING Selleys No More Cracks Exterior Wood Filler is hazardous according to the health criteria of Safe Work Australia. The signal word is Warning. It is classified as NON-Dangerous Goods. Hazard statement: CodeStatementClassificationWhat This MeansH317May cause an allergic skin reactionSkin Sensitisation Cat 1Contact with skin may result in irritation. A skin sensitiser. 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 irritate mucous membranes and the respiratory tract. It may be an eye irritant. Dust exposure may cause discomfort due to particulate nature. 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. In addition, P280 for this product specifically requires a suitable respirator. Dust from sanding exterior wood repairs and particulate matter during application can irritate mucous membranes and the respiratory tract. 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 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 and dust may cause discomfort due to particulate nature. Suitable respirator: Required by P280. Protects against dust, fume, gas, mist, vapours, or spray per P261. Overalls and safety shoes: Full body coverage minimises skin contact with the sensitiser. Contaminated work clothing should not be allowed out of the workplace. Wash contaminated clothing before storing or re-using. Engineering: Natural ventilation should be adequate under normal use conditions. Hygiene: Keep away from food, drink, and animal feeding stuffs. When using, do not eat, drink, or smoke. Wash hands before smoking, eating, drinking, or using the toilet. Avoid eye contact and skin contact. Avoid inhalation of dust. Ensure eyewash stations and safety showers are close to the workstation location.

Product Overview This product is specifically designed for exterior timber. Its key characteristics: Weather resistant flexible filler — unlike rigid interior fillers, this product flexes with the wood's natural movement caused by seasonal moisture and temperature changes. This is why it will not crack, split, or fall out over time. Suitable for all exterior timber — the product is formulated for the exposure conditions that exterior timber faces. Priming is unnecessary before filling — you can apply the filler directly to clean, dry timber without priming first. Can be nailed or planed — once dried, the repair can be nailed through or planed without damage, with minimal shrinkage. Stainable, paintable, tintable, and varnishable — the pine coloured paste can be finished in multiple ways. When tinting or staining, note that the final colour is not achieved until varnish is applied.

Prepare the Surface Ensure the surface to be filled is clean and dry with no loose or powdery material. Remove rotten wood and fix split timber firmly before filling. Any rotten or loose wood must be removed — the filler needs sound timber for proper adhesion. Split timber should be secured back in place before applying filler.

Apply the Filler The product is ready to use straight from the tub — no mixing required. Press filler firmly into the surface and remove excess. Use a filling blade or scraper to firmly press the filler into the crack, hole, or imperfection. Scraping off excess reduces sanding later. For deeper repairs, apply in 10mm layers. Allow each layer to dry before applying the next. This prevents the surface from drying while the interior remains uncured.

Drying Times Drying times at 25°C: DepthDrying Time2–3mm2–3 hours10mm+16 hours For deeper repairs applied in 10mm layers, allow each layer to fully dry (16+ hours at 25°C) before applying the next layer.

Sand and Finish Sand and paint or stain after drying. Once the filler is fully dry, sand with fine sandpaper and apply your chosen finish. Staining and tinting: The product can be stained, tinted, or varnished. When tinting or staining, the final colour is not achieved until varnish is applied. Start with a light application of stain — the tone can be progressively darkened by applying more stain. Painting: For best results if painting, apply an undercoat before your top coat. Protect from rain until painted. The repair must be protected from rain until the final paint or stain coat is applied.

Clean Up and Storage Uncured product: Clean tools and hands with water before filler dries. Cured product: Once dried, cured filler can be removed by sanding and scraping. Storage: Store in a cool, dry, well-ventilated place out of direct sunlight. Store away from foodstuffs, incompatible materials (oxidising agents), and sources of heat and/or ignition. Keep container standing upright. Keep containers closed when not in use. 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

Not for permanently wet areas — the product is weather resistant but not designed for areas subject to constant water immersion or permanent wetness Not for joints subject to movement — specifically not for joints between weatherboards, floorboard panels, etc. Where movement occurs, use Selleys No More Gaps Exterior & Weatherboard instead Do not use below 5°C — cold conditions prevent proper drying Protect from rain until painted — the repair must be protected from rain exposure until the final finish coat is applied

Tips for Best Results Remove rotten wood and fix splits before filling. Sound timber is essential for proper adhesion. Rotten wood crumbles under the filler and causes failure. Apply in 10mm layers for deeper repairs. Each layer needs to dry fully before the next. At 10mm depth, allow 16+ hours at 25°C per layer. Priming is unnecessary before filling. Apply directly to clean, dry timber. Protect from rain until painted. Schedule exterior repairs for dry weather and apply finish coat promptly. When tinting or staining, final colour is not achieved until varnish is applied. Test on an inconspicuous area first to determine the amount of staining required for a colour match. For best results if painting, apply an undercoat before your top coat. This creates a uniform base for the topcoat. Clean tools with water before filler dries. Once cured, removal requires sanding or scraping.

Troubleshoot Common Problems Problem: Filler not dry after 2–3 hours Drying times depend on depth and temperature. At 10mm depth, expect 16+ hours at 25°C. Cold conditions extend drying further. Do not apply next layer until previous is fully dry. Problem: Filler cracks or falls out Ensure rotten wood was removed and splits fixed before filling. This product is designed to flex with wood movement and should not crack, split, or fall out when applied to sound timber. If the joint is subject to movement (e.g., between weatherboards), use Selleys No More Gaps Exterior & Weatherboard instead. Problem: Stain colour doesn't match Final colour is not achieved until varnish is applied. Start with a light application and darken progressively. Test on an inconspicuous area first. Problem: Paint peeling over repair Apply an undercoat before the top coat for best results. Ensure the repair was fully dry before painting. Problem: Rain damaged repair before painting Protect from rain until painted. If rain exposure occurred, allow to dry completely and assess whether re-application is needed. Problem: Filler won't adhere Ensure surface is clean and dry. Remove all rotten wood. Fix split timber firmly before filling.
