Skimming Spatulas Explained: The Benefits of X-SKIM and SUPERSKIM
Share
When it comes to achieving smooth, consistent plaster finishes in less time and with less physical strain, skimming spatulas have become essential tools for professional plasterers and decorators. Unlike traditional trowels, skimming spatulas are specifically engineered to cover large surface areas quickly while maintaining control and finesse. In this article, we’ll explore what makes skimming spatulas different, outline the key benefits they offer, and explain why REFINA’s X-SKIM and SUPERSKIM X-LITE ranges are trusted by tradespeople across the UK.
What Is a Skimming Spatula?
A skimming spatula is a wide-bladed finishing tool used in plastering and drywall taping to smooth and level joint compounds, finish coats, and skimming coats over large wall and ceiling surfaces. Typically featuring stainless steel or flexible composite blades, skimming spatulas are designed to deliver broad, even strokes that reduce the number of passes needed to achieve a flat, polished surface.
Unlike conventional plastering trowels, which require more wrist movement and a steeper angle of application, skimming spatulas are used at a shallower angle with minimal wrist strain. This design not only improves coverage speed but also helps reduce fatigue, particularly during extended use or overhead work.
Key Benefits of Using Skimming Spatulas
1. Faster Surface Coverage
The wider blades, often ranging from 10″ up to 48″, enable plasterers to cover large areas more quickly than with standard trowels. This increased productivity is especially valuable on commercial jobs, new builds, or multi-room renovations.
2. Superior Finishes
Skimming spatulas glide over the surface and feather edges more smoothly than rigid trowels. This results in fewer lines, ridges, or lap marks, allowing for a finer, flatter finish that requires minimal sanding.
3. Reduced Arm and Wrist Strain
Thanks to their ergonomic design and shallow angle of operation, spatulas place less stress on joints, particularly during ceiling work. This makes them ideal for daily use and helps reduce the risk of repetitive strain injuries (RSIs).
4. Cleaner Working Method
Because spatulas produce fewer lines and edges that need reworking, there is less back-and-forth needed, saving not only time, but also minimising mess and rework.
The REFINA Range: X-SKIM vs SUPERSKIM

- Interchangeable Blade System: Swap blades quickly and easily to suit each stage of your project. This system also offers a cost-effective way to replace worn blades without needing to purchase a complete new spatula.
- Contoured Grip Handle: Designed for balance and ergonomic comfort, ensuring a steady, comfortable grip even during longer plastering sessions.
Best Suited For:
- Base Coat Flattening: The X-SKIM excels in levelling out freshly applied base coats, such as bonding plaster or hardwall, by distributing consistent pressure across its blade. This helps achieve a uniform, flat surface early in the plastering process, reducing the need for rework and ensuring a smoother foundation for subsequent finishing coats.
- Multi-Finish Plaster: Designed for optimal performance with gypsum-based multi-finish plasters, the X-SKIM allows for seamless feathering and precise edge control. Its rigid profile makes it ideal for pulling through larger areas of setting plaster, maintaining flatness while eliminating ripples or drag marks, even as the material begins to firm up.
- Drywall Jointing Compounds: When working with jointing compounds on taped seams or board junctions, the X-SKIM provides the perfect combination of blade width, blade flexibility and profile rigidity to flatten joints quickly and accurately. This is especially beneficial for achieving invisible joints over larger spans and reducing sanding time before decoration.
- Large Commercial or Domestic Skimming Jobs: For high-volume work on new builds or whole-property renovations, the X-SKIM’s wide blade reduces the number of strokes needed to skim walls and ceilings, improving productivity and reducing operator fatigue. Its robust construction withstands repeated use in demanding environments, enabling teams to meet deadlines without compromising finish quality.
If your project requires pressing down on fresh plaster, achieving sharp angles, or maintaining a defined feathered edge, the X-SKIM offers the control and durability needed for repeatable results.
