Refina Professional 12″ Comb Scarifier: 90mm Stainless Steel Prongs
Prepare your external substrates quickly and accurately with the premium 12″ scarifier from Refina. This trade-grade rendering tool features semi-flexible stainless steel tines designed specifically for EWI contractors across the UK. Consequently, it works perfectly for scratching monocouche surfaces, keying polymer basecoats, and scoring underlying backing plasters smoothly. Additionally, it offers exceptional aggregate leveling parameters to deliver an optimal keying texture before subsequent finish layers are applied.
Notice: Product handle component configurations, bracket accents, or prong color shades may vary slightly from the website display photos depending on current manufacturer manufacturing batches and supplier stock availability.
Key Features of the Refina 12″ Render Comb Scarifier
- Semi-Flexible Stainless Steel Tines: The 90mm rust-free metal spikes are arrayed evenly into a rigid reinforcement beam. Therefore, it completely eliminates prong bending under heavy leverage and ensures an evenly matched scratch finish across wide surface planes.
- Lightweight Aluminum Mounting Bracket: Engineered with a heavy-duty, low-weight aluminum core body matrix. Because of this design, it provides uniform leverage distribution down through the prongs while reducing hand fatigue.
- Robust Wooden Grip Construction: Features a contoured classic wooden handle assembly attached firmly to the frame assembly. As a result, the tool provides a solid grip and outstanding control when dragging through wet masonry mortars.
- Efficient Surface Laitance Removal: Designed explicitly to key scratch surfaces effortlessly before the final structural set takes place. Furthermore, it rolls over modern render applications seamlessly without digging deep gouges or fracturing underlying plaster blocks.

UK Application Guidelines for Render Scarifiers
For more detailed data on structural anchor patterns and building compliance, you can read the official UK Building Regulations Approved Document L guidelines.
- First, apply your single-coat monocouche or primary basecoat layer tightly using standard trowelling techniques. For ideal system compatibility, browse our complete collection of EWI installation basecoats.
- Next, allow the material to set for roughly 2 to 4 hours depending on local atmospheric variables before processing.
- Subsequently, place the Refina 12″ scarifier face flat and drag the tines uniformly across the damp render coat to expose aggregates.
- Finally, clean out any jammed masonry particles from between the stainless steel spikes using a stiff wire brush between passes to avoid marking lines. Always adhere to application standards outlined in the INCA Best Practice Guides.
