All Purpose Filler – R&G Filler Material for Every Surface
Whether you need a filler material for walls, a wood filler for repairs, or a fine filler for smooth surfaces – at R&G you will find the right all purpose filler for every application. Our range includes high-quality products for professionals and DIY enthusiasts alike, delivering easy application, excellent adhesion, and long-lasting results.
What Is Filler Material?
Filler material is a paste-like compound used to fill and level uneven surfaces, cracks, and damaged areas on a wide variety of substrates. Depending on its composition, it is suitable for different applications – from fine surface finishing to structural repair. Many of our products are water-dilutable, making them particularly easy to handle.
Types of Filler Material at a Glance
Fine Filler – For Smooth Surfaces and Detail Work
Fine fillers are ideal for levelling minor surface imperfections and smoothing pre-treated areas. Used as a filling compound, they close fine cracks and hairline cracks to achieve a uniform surface. Typical products include the Presto SF Polyester Fine Filler (styrene-free) and the Colormatic 2K Soft Fine Filler – both are characterised by excellent sandability and a smooth finish.
Fibre Filler – For Larger Damaged Areas and Structural Repairs
For deeper damage, holes, or rust-through areas, a fibre filler – such as a glass fibre-reinforced filler – is the better choice. The Colormatic 2K Glass Fibre Filler offers significantly higher strength thanks to its glass fibre reinforcement and is well suited to substrates exposed to tensile and flexural forces.
Spray Filler – Fast and Easy Application
For smaller repair jobs, the Presto Finish Spray Filler is a practical alternative to manual application. This high-quality acrylic spray filler quickly and professionally closes minor surface imperfections, scratches, and sanding marks on coated surfaces. Thanks to its short drying time, it can be sanded quickly and applied in multiple coats – ideal for efficient repair work.

Applications for Filler Material
Filler Material for Walls & Interiors
For filling walls and ceilings in interior spaces, fine fillers and wall fillers are particularly well suited. They level uneven surfaces, close cracks, and create a uniform base for paint or wallpaper.
Filler Material for Cars & Vehicle Repair
In the automotive sector, both fine fillers and fibre fillers are used. The Colormatic 2K Universal Filler is an excellent multi purpose filler for body panels and metal surfaces. For deeper damage, the glass fibre filler is recommended.
Wood Filler & Wood Repairs
For wood repairs and filling wooden surfaces, specialist wood fillers are the ideal solution. The Colormatic 2K Universal Filler adheres reliably to wood and is well suited for the restoration and repair of wooden surfaces.
Further Applications
For use in boat building or underwater environments, we recommend the Presto Epoxy Filler , which offers outstanding water resistance. The YC KK-Plast VT is available as a filler material in various container sizes.
Applying Filler Material – Tips & Guidance
The best results are achieved on a properly prepared substrate:
- Prepare the surface: Clean, degrease, and sand the substrate
- Mix the filler: For 2K products, add the hardener exactly as specified by the manufacturer
- Apply: Spread evenly and draw smooth
- Allow to dry: Observe the drying time according to the product and ambient temperature
- Sand: Once cured, sand to achieve a smooth, even surface
Tip: For larger damaged areas, first fill with fibre filler, then finish with fine filler for a smooth result.
FAQ – Frequently Asked Questions About All Purpose Filler & Filler Material
Which filler material for which purpose?
The choice depends on the type of damage and the substrate. Fine filler is suitable for minor imperfections and smooth surfaces; fibre filler is the right choice for deeper damage and structural repairs. For holes and cracks, 2K products such as the Colormatic 2K Universal Filler are recommended as a reliable all purpose filler.
Which filler material adheres to wood?
For wood repairs, polyester-based wood fillers such as the Presto SF Polyester Fine Filler are well suited. They adhere reliably to wood and can be sanded and painted with ease.
Is there a waterproof filler material?
Yes – for damp areas and underwater applications, we recommend the Presto Epoxy Filler . This 2K epoxy filler is exceptionally water-resistant and has been specifically developed for use in boat building.
Which filler material for cracks?
For fine hairline cracks, fine filler is the appropriate choice. For deeper cracks and rust-through damage, the Colormatic 2K Glass Fibre Filler is recommended. For concrete cracks, specialist epoxy fillers with strong adhesion to mineral substrates are advisable.
Which filler material for interior use?
For interior applications, water-dilutable wall fillers and fine fillers are particularly well suited. They are low-odour, easy to apply, and sand well. The Presto SF Polyester Fine Filler is styrene-free, making it especially pleasant to work with indoors.
What is the drying time for filler material?
Drying time varies depending on the product, temperature, and layer thickness. 2K polyester-based products are often sandable after 20–30 minutes. Water-dilutable filler materials generally require longer. Full cure can take several hours depending on the product.
