Plastering Hawks and Boards: How to Choose and Use
Quick Answer: A plastering hawk (or hand board) is an essential tool that holds plaster while you work, typically a flat aluminium or plastic square (270-330mm) with a handle underneath. Combined with a trowel, it’s the fundamental duo for applying plaster efficiently. Quality hawks cost £12-£35, with professional-grade aluminium models from brands like Refina and Marshalltown being the gold standard. The hawk keeps plaster at arm’s reach, reduces trips to your mixing bucket, and allows single-handed operation whilst maintaining a smooth workflow. What Is a Plastering Hawk and Why Do You Need One? A plastering hawk is a flat, square board with a perpendicular handle fixed to its underside. You hold it in your non-dominant hand whilst working with a trowel in your dominant hand. It’s fundamentally a portable plaster platform that sits just below your working area. The hawk serves several critical functions that make it indispensable on any plastering job: Plaster reservoir: Holds 1-2kg of mixed plaster at a time, reducing constant trips to your bucket Single-handed operation: Frees up your trowel hand to work continuously without interruption Workflow efficiency: Positioned at the perfect angle for loading your trowel quickly Material control: Prevents plaster from drying out too quickly compared to leaving it in a bucket Professional technique: Essential for proper hawk-and-trowel methodology taught in CITB plastering qualifications Without a hawk, you’d need to constantly bend to your bucket, breaking your rhythm and creating an inefficient, physically draining workflow. Professional plasterers can work for hours using proper hawk technique, whereas beginners without one tire quickly and produce inconsistent results. Types of Plastering Hawks: Materials and Designs Not all hawks are created equal. The material, size, and construction directly impact durability, weight, and performance. Here’s what’s available in 2026: Aluminium Hawks (Professional Standard) Aluminium hawks are the industry standard used by 90% of professional plasterers across the UK. They offer the optimal balance of lightweight construction and durability. Key characteristics: Weight: 400-600g (light enough for all-day use) Standard sizes: 280mm, 300mm, 330mm square Price range: £18-£35 for quality models Lifespan: 5-10+ years with proper care Surface: Smooth aluminium that won’t rust or corrode Premium brands include Refina, Marshalltown, and OX Tools. These feature properly welded handles, bevelled edges to prevent plaster build-up, and perfectly flat surfaces. You’ll find them at Screwfix, Toolstation, and specialist trade suppliers. Plastic Hawks (Budget Option) Plastic hawks cost £8-£15 and work adequately for DIY projects or occasional use. However, they have significant drawbacks for professional work: Flexibility issues: Can warp or flex when loaded with heavy plaster Durability concerns: Handles can snap under repeated stress Surface texture: Some plastics allow plaster to stick more than aluminium Limited lifespan: Typically 1-2 years for regular users Plastic hawks suit homeowners doing a single room or apprentices learning basic technique before investing in professional tools. Wooden Hawks (Traditional but Obsolete) Traditional wooden hawks were standard until the 1980s but are now rare. Wood absorbs moisture, warps over time, and requires maintenance (sanding and sealing). Most professionals abandoned them decades ago, though some heritage restoration specialists still use them for authenticity on listed building projects. Specialist Hawks Several niche variations exist for specific applications: Type Description Use Case Price Range Rendering Hawk Larger (350-400mm), heavier construction External rendering, holding more material £25-£45 Corner Hawk 90° angled design Internal/external corner work £22-£35 Lightweight Hawk Thin aluminium (300-400g) Ceiling work, reduced arm fatigue £20-£30 Magnetic Hawk Integrated magnets for tool storage Holding trowels whilst loading hawk £28-£40 Choosing the Right Size Hawk Size matters significantly when selecting a hawk. The wrong size causes arm fatigue, inefficient plaster management, or difficulty maneuvering in tight spaces. Standard Sizing Guide 280mm (11″): Ideal for small rooms, bathrooms, tight spaces. Lighter and easier for beginners or those with smaller builds. Holds approximately 1-1.5kg of plaster. 300mm (12″): The most popular all-rounder size. Suitable for 90% of domestic plastering work. Holds 1.5-2kg comfortably. Recommended for most tradespeople. 330mm (13″): Preferred by experienced plasterers on larger jobs. Holds 2-2.5kg. Requires stronger arm and wrist strength but maximizes efficiency on big walls. Most professionals own multiple sizes, selecting based on the specific job. A bathroom plastering project might suit a 280mm hawk, whilst a large lounge calls for a 330mm. Pro Tip: Your hawk size should match your physical build and the typical room sizes you work in. If you’re 5’6″ and work mainly in standard UK terraced houses, a 300mm hawk is perfect. If you’re 6’2″ doing new-build estates, consider a 330mm for efficiency. Start with a 300mm if unsure—it’s the Goldilocks size that works for almost everything. Plastering Hawks vs. Spot Boards: Understanding the Difference Beginners often confuse hawks with spot boards, but they serve completely different functions in the plastering workflow. Spot boards are larger flat boards (typically 600-900mm square) placed on a stand at waist height. They hold your bulk plaster supply—the bucket of mixed material you’re working from. You load your hawk from the spot board, not directly from the mixing bucket. Hawks are handheld, holding only the small amount of plaster you’re actively applying at that moment. The professional workflow looks like this: Mix plaster in bucket using a plastering whisk and drill Transfer mixed plaster to spot board on stand Load hawk from spot board (2-3 trowel loads) Apply from hawk to wall using trowel Return to spot board when hawk is empty This system keeps your working material at the perfect height and consistency, prevents contamination, and creates an efficient production line. How to Hold and Use a Plastering Hawk Properly Proper hawk technique is fundamental to plastering efficiency and quality. Poor technique causes arm fatigue, dropped plaster, and inconsistent application. The Correct Grip Hold the hawk handle with your non-dominant hand, fingers wrapped around the handle with your thumb on top. Your hand should be in a natural, relaxed position—not gripping tightly. Key positioning elements: Hawk tilted at approximately 30-45° angle toward your body Positioned at chest to shoulder height for optimal loading Elbow bent at roughly
