One Strike Filler
(5 Products)One Strike Filler provides a high-performance, lightweight solution for repairing gaps and holes in walls and ceilings in a single application. Formulated using advanced polymer technology, this filler is designed to finish surfaces without the need for secondary layers, ensuring a smooth, ready-to-paint surface that will not shrink or crack.
Understanding One Strike Filler
One Strike Filler is an ultra-lightweight repair compound engineered for speed and efficiency in internal decorating and maintenance tasks. Unlike traditional gypsum-based fillers that often require multiple applications due to evaporation and shrinkage, this polymer-based formula maintains its volume as it cures. This "one-strike" capability allows for the filling of deep cavities—up to 75mm in a single pass—without the sagging or slumping typically associated with heavy-weight fillers.
The material’s unique consistency resembles a light paste, which facilitates easy application with a filling knife or spreader. Once applied, the filler dries rapidly to a smooth finish that usually requires little to no sanding, significantly reducing airborne dust on site. It provides an ideal substrate for all types of emulsion and oil-based paints, as well as wallpaper, without the risk of "flashing" or ghosting through the final finish.
Available in a range of volumes from 250ml tubs for minor domestic touch-ups to 5L buckets for large-scale commercial renovations, the chemical composition remains consistent across the entire range. Its versatility makes it suitable for use on a wide variety of internal substrates, including plaster, brick, stone, wood, and even rendered surfaces, provided they are clean and dry before application.
Material Range
- Lightweight Repair Compound: A consistent, high-performance polymer formula available in various sizes - featuring 250ml, 1L, 2.5L, and 5L containers - to suit the scale of the specific repair task.
Performance Benefits
- Non-Shrink Formula: Maintains its original volume during the drying process, eliminating the need for overfilling or secondary applications.
- Rapid Cure Time: Dries quickly to a finish that is typically ready to paint in approximately 30 minutes, depending on ambient conditions.
- Sanding-Free Finish: Dries to an exceptionally smooth surface, often removing the requirement for abrasive finishing and reducing site dust.
- High-Volume Filling: Capable of filling holes up to 75mm deep in one application without sagging or cracking.
Typical Applications
- Plaster Repair: Filling deep cracks, gouges, and impact damage in plastered walls and ceilings.
- Fixture Remediation: Filling holes left by the removal of wall plugs, screws, or electrical fittings.
- Joinery Preparation: Filling nail heads and minor imperfections in internal timber trim before painting.
- Pre-Decoration Levelling: Smoothing out uneven masonry or stone surfaces prior to the application of wallcoverings.
Specification & Standards
- BS EN 13963: Jointing materials for gypsum boards. Definitions, requirements, and test methods.
- ISO 16000-9: Compliance with low VOC emission standards for indoor air quality.
- ASTM C475: Standard specification for joint compound and joint tape for finishing gypsum board (relevant for performance benchmarks).
Related Materials and Construction Uses
One Strike Filler is a critical component in the preparation phase of interior decoration. It is most effective when used on surfaces previously cleaned of loose debris and dust. For deep repairs in highly porous substrates, the area may be primed with a diluted PVA solution to ensure maximum adhesion. Once dry, the filler integrates perfectly with standard decorative systems, including water-based emulsions and solvent-based undercoats, providing a seamless transition between the repaired area and the original substrate.
Frequently Asked One Strike Filler Questions
What Depth Can One Strike Filler Be Applied In A Single Application?
It is typically suitable for filling depths up to approximately 50mm in one application, depending on substrate and cavity size. For deeper voids, staged filling may be required to ensure proper curing and adhesion.
Is One Strike Filler Suitable For Structural Repairs?
One Strike Filler is intended for non-structural surface repairs only. It should not be used where load-bearing performance is required or where movement is anticipated beyond normal building tolerances.
How Long Does One Strike Filler Take To Dry?
Drying time depends on depth of fill, temperature, and ventilation. Shallow repairs may dry within one to two hours, while deeper sections require extended drying before sanding or overpainting.
