Jargon Buster

• Two-Part Wood Filler: A resin-based repair system consisting of a base compound and hardener that are mixed together before application. These provide exceptional strength and durability, ideal for structural repairs and exterior use where moisture resistance is essential.
• Grain Filler: A paste-like product designed to fill the natural pores in open-grained woods such as oak, ash, or mahogany, creating a smooth surface before applying finish coats. Particularly important for achieving high-quality painted or lacquered finishes.
• Wax Filler Stick: A solid wax-based product that melts slightly with friction, allowing it to be rubbed into small scratches, dents, and imperfections. Available in various wood tones for quick cosmetic repairs on finished surfaces.
• Wood Hardener: A liquid penetrating solution that consolidates and strengthens damaged, rotten, or soft timber by soaking into the fibres. Typically used as a preparatory treatment before applying wood filler to compromised areas.
• Flexible Filler: A wood repair compound that remains slightly pliable after curing, accommodating the natural expansion and contraction of timber. Particularly useful for exterior joinery and areas subject to movement or vibration.
• Stainable Filler: A wood repair product formulated to accept wood stains and dyes, allowing repairs to blend seamlessly with the surrounding timber's natural colour and grain pattern.

How to Choose the Right Wood Repairer

Location and Exposure: Determine whether the repair is for interior or exterior use. Exterior applications require weather-resistant, flexible fillers that can withstand UV exposure, moisture, and temperature fluctuations. For structural exterior repairs, two-part epoxy systems offer superior durability and water resistance, whilst interior cosmetic repairs may only require standard ready-mixed fillers.

Size and Type of Damage: Small scratches and minor dents can often be addressed with wax filler sticks for quick cosmetic fixes, whilst larger holes, splits, or areas of rot require substantial fillers or two-part repair systems. For deep repairs exceeding 10mm, apply filler in layers, allowing each to cure before adding the next.

Finish Requirements: Consider how the repaired surface will be finished. If you're planning to stain the timber, ensure you select a stainable filler. For painted finishes, most standard fillers will suffice, but check they can accept paint without primer. Natural or clear-finished wood requires careful colour matching—many manufacturers offer fillers in various wood tones.

Drying and Curing Time: Quick-drying fillers are ideal for fast-turnaround work on site, curing in as little as 15-30 minutes, allowing you to sand and finish rapidly. Two-part systems may take longer to cure but offer superior strength. Consider your project timeline when selecting products from the Tooled-Up range.

Workability and Application: Ready-mixed fillers in tubs offer convenience for everyday repairs, whilst two-part systems require mixing but provide greater versatility. Some products are designed for trowel application, others for injection into cracks or application with filling knives. Consider the tools you have available and the nature of the repair.

Structural Requirements: For load-bearing repairs or areas subject to stress, opt for high-strength two-part epoxy wood fillers that can be drilled, sawed, planed, and sanded once cured. Standard cosmetic fillers are unsuitable for structural applications.

Safety Information

Ventilation: Many wood fillers and hardeners contain solvents that release fumes during application and curing. Always work in well-ventilated areas, particularly when using two-part epoxy systems or solvent-based products. For extensive interior work, consider using extraction equipment or respiratory protection in accordance with HSE guidelines.

Skin Protection: Two-part epoxy resins and hardeners can cause skin sensitisation and irritation. Wear appropriate protective gloves—nitrile gloves offer good chemical resistance. Avoid skin contact, and if contact occurs, wash immediately with soap and water. Barrier creams provide an additional layer of protection for frequent users.

Dust Control: Sanding cured wood filler generates fine dust particles. Use dust extraction where possible, and wear appropriate dust masks or respirators, particularly when working with materials that may contain silica. Comply with HSE workplace exposure limits for wood dust and respirable particles.

Storage and Disposal: Store wood repair products in sealed containers away from heat sources and out of reach of children. Two-part systems should have components stored separately. Dispose of unused materials and contaminated rags according to local authority guidelines and COSHH regulations. Note that some solvent-laden materials can spontaneously combust if not disposed of properly.

Frequently Asked Questions

Can wood filler be used outdoors?
Not all wood fillers are suitable for exterior use. Standard interior fillers may crack, shrink, or degrade when exposed to moisture and UV light. For exterior applications, choose products specifically labelled as exterior-grade or weather-resistant. Two-part epoxy wood fillers generally offer the best performance outdoors, providing excellent water resistance and durability. Always apply wood preservative to bare timber before filling exterior repairs.

How do I match the colour of wood filler to my timber?
For stained or natural finishes, select a filler slightly lighter than your timber, as it will typically darken when stain is applied. Many manufacturers offer colour-matched fillers for common wood species like oak, pine, and mahogany. Alternatively, use neutral fillers that accept stain, allowing you to colour-match after application. For painted finishes, filler colour is less critical as it will be covered. Test colour matching on an inconspicuous area first.

What's the difference between wood filler and wood putty?
Wood filler is typically water-based, dries hard, and can be sanded, drilled, and painted once cured—ideal for repairs that need structural integrity. Wood putty is usually oil-based, remains slightly flexible, and is better suited for filling small gaps and nail holes in finished wood. Putty is often used for final touch-ups after finishing, whilst filler is applied before finishing. For repairs requiring strength and sandability, wood filler is the better choice.

How long should I wait before sanding wood filler?
Drying times vary significantly between products. Quick-drying ready-mixed fillers may be ready to sand in 15-30 minutes for shallow applications, whilst deeper fills may require several hours. Two-part epoxy fillers typically cure within 2-4 hours but check manufacturer specifications. As a rule, filler should feel completely hard and show no tackiness before sanding. Attempting to sand too early can clog abrasives and create an uneven finish.

Can I drill or screw into wood filler?
High-strength two-part epoxy wood fillers can accept screws and be drilled once fully cured, making them suitable for semi-structural repairs. Standard ready-mixed fillers generally lack the strength to hold fixings reliably and may crumble under stress. If you need to fix into a repair, use a two-part system and allow complete curing (typically 24 hours) before drilling. Pre-drilling pilot holes reduces the risk of splitting the repair.
