The Harris Ultimate Walls & Ceilings Blade Paint Brush represents the highest standard in interior painting tools, specifically designed for precision work with emulsion paints. Central to its performance is the proprietary Blade Technology, which features ultra-fine tapered filament tips that form a razor-sharp edge. This advanced bristle structure allows decorators to achieve crisp, defined lines around sockets, ceiling junctions, and intricate trim without relying on masking tape. The 2” width offers a perfect balance of accuracy and efficiency, making it suitable for both detailed edging and small surface areas where rollers cannot reach. Ideal for cutting in along skirting, coving, or mouldings, the brush allows for smooth, controlled application in just a few strokes.
Crafted as part of Harris’ premium ‘Ultimate’ range, this brush is built to meet the expectations of professional painters and demanding DIY users alike. Its densely packed synthetic filaments ensure consistent paint delivery across both smooth and slightly textured surfaces, while the NO-LOSS technology prevents bristle shedding for a flawless finish every time. The ergonomic handle has been shaped for comfort during prolonged use, helping to reduce strain when working on large projects or tackling awkward angles. Compatible with all standard water-based emulsions—including specialist coatings like Anti-Mould or breathable wall paints—the brush delivers reliable performance across a wide range of interior applications. From tight spaces behind fixtures to detailed refurbishment work, the Harris Ultimate Walls & Ceilings Blade Paint Brush offers the control and finish quality needed for top-tier decorating results.

Edging Between Walls and Ceilings: Allows for sharp, controlled lines along the edges of walls and ceilings where a roller cannot reach effectively, enhancing the overall finish.
Trim and Detail Work: Suitable for painting skirting boards, architraves, and corner details where neat edges are critical and space is limited.
Internal Wall Preparation: Perfect for tackling tricky sections of smooth or semi-smooth internal walls, such as newly plastered areas, older painted walls, or those with minor surface variations.
Touch-Ups and Corrections: Useful for returning to areas requiring further refinement or paint correction after main coverage has been applied with rollers.
This paint brush is suitable for use on most internal surfaces requiring emulsion application. Typical substrates include plasterboard, previously painted plaster, smooth and semi-smooth walls, and ceiling surfaces.
It is also effective when working on edges, corners, around plug sockets, light switches, and other detailed interior areas where neat, accurate lines are essential.
Before applying paint, surfaces should be thoroughly cleaned to remove dust, dirt, grease, or loose material. If painting over previously coated walls, sand down any uneven areas and wipe clean with a damp cloth.
On newly plastered surfaces, ensure full drying and prime with an appropriate mist coat before finishing with emulsion. Clean, dry, and stable surfaces will provide the best results and prolong the life of the brush.
For best results, gently rub the brush with a clean hand before use to remove any dust particles that may affect the finish. Do not pre-wet the bristles. Load the brush with emulsion paint, removing excess on the rim of the paint container.
Use smooth, deliberate strokes for high-precision cutting in along trim, wall edges, and awkward junctions. Harris’ unique Blade Technology allows the tapered head to deliver crisp lines and even coverage with a single dip, helping to reduce drag and paint marks during use.
After use with water-based paints such as standard emulsions, remove as much excess paint as possible. Wash the bristles thoroughly in warm, soapy water or rinse under clean running water.
Cleaning should be done immediately after use to prevent paint from drying within the bristles. Avoid soaking the brush or leaving it in damp conditions, as this may cause bristle loss and shorten the lifespan of the brush.
Once cleaned, the brush should be dried thoroughly before storing. Lay the brush flat or store it in its protective case if supplied. Allowing the bristles to dry in a natural position helps preserve the shape and maintain precision for future use.
Proper aftercare is essential to retain the performance of the bristles and ensure consistent results across multiple projects.
This product is specifically designed for use with emulsion paints only and should not be used with oil-based or solvent-based coatings. Bristle loss may occur if left to soak or stored in a humid environment.
Always refer to the manufacturer’s guidance on the paint tin for any specific cleaning instructions or compatibility notes when using specialist emulsions or additives.
A) The Harris Ultimate Walls & Ceilings Blade Paint Brush is specifically designed for precision work with emulsion paints on interior walls and ceilings. Its 2-inch width and finely tapered bristles—developed using Harris’ proprietary Blade Technology—allow users to create crisp, clean edges without the need for masking tape. This makes it ideal for cutting in around plug sockets, light switches, ceiling lines, and trims where accuracy is crucial. The brush excels in delivering a smooth, controlled paint application, especially in areas where a roller cannot reach effectively. Whether you’re painting new plaster, refurbishing an older property, or just refreshing a room, this brush ensures that neat, professional-looking lines are achieved with minimal effort and high consistency.
A) The defining feature of the Harris Ultimate Walls & Ceilings Blade Paint Brush is its advanced Blade Technology, which gives the bristle tips an ultra-fine taper. This design provides a razor-sharp edge, allowing for far greater control than traditional brushes. It enables decorators to apply straight, crisp lines with minimal overspill or bleeding, making it especially valuable for cutting in around fixtures and fittings. Unlike standard paint brushes, this one also includes NO-LOSS technology, meaning the bristles are securely fixed and will not shed during use—eliminating a common frustration in decorative work. The synthetic bristles are optimised for water-based emulsion paints and deliver an even flow, while the ergonomic handle supports comfortable use during extended decorating tasks. It’s a high-performance brush for high-precision jobs.
A) Absolutely. Cutting in is where the Harris Ultimate Walls & Ceilings Blade Paint Brush truly shines. The finely tapered bristles, created through Harris’ Blade Technology, allow users to produce ultra-clean lines along edges, corners, and joins. This makes the brush especially well-suited for detailed areas such as the junction between walls and ceilings, along skirting boards, and around light switches and sockets. The 2-inch width offers a perfect balance—it’s wide enough to cover a reasonable surface area yet narrow enough to manoeuvre with precision. Many decorators find that with a steady hand, this brush removes the need for masking tape entirely, speeding up the process without compromising the finish. Its exceptional paint flow and easy control make it a go-to tool for high-quality edge work.
A) The Harris Ultimate Walls & Ceilings Blade Paint Brush is optimised specifically for use with water-based emulsion paints. This includes matt, silk, soft sheen, and washable emulsions typically used on internal walls and ceilings. The synthetic bristles are engineered to hold and release emulsion evenly, giving you a smooth and consistent finish with each stroke. It is not suitable for use with oil-based or solvent-based paints, as these can affect the integrity of the bristles and compromise the precision edge. When using specialist emulsions such as stain-blockers or mould-resistant formulations, it’s always best to check the product label for brush compatibility, though this brush typically performs very well across all standard emulsion ranges.
A) The Harris Ultimate Walls & Ceilings Blade Paint Brush is suitable for a wide variety of internal surfaces typically coated with emulsion paints. These include smooth or slightly textured plaster walls, previously painted surfaces, lining paper, and ceiling areas. It’s also effective for cutting in around architectural features like coving, architraves, and skirting boards. The blade-shaped bristles offer excellent control on uneven surfaces, allowing you to maintain neat, defined lines even when working with older or imperfect walls. It is especially effective on newly plastered surfaces when finishing around edges after the mist coat has been applied. As long as the substrate is dry, clean, and properly prepared, this brush will perform to a very high standard.
A) Proper surface preparation is essential for achieving the best results with the Harris Ultimate Walls & Ceilings Blade Paint Brush. Begin by ensuring the surface is dry, clean, and free from dust, grease, or flaking paint. For previously painted walls, lightly sand any rough areas to create a smooth base, and wipe clean with a damp cloth. New plaster should be fully dry and primed with a mist coat to seal the surface before applying your chosen emulsion. Pay special attention to edges, corners, and areas around sockets or switches, as these are the spots where the brush is likely to be used most. Clean preparation not only improves the quality of your finish but also helps prolong the lifespan of the brush itself.
A) To get the most from the Harris Ultimate Walls & Ceilings Blade Paint Brush, begin by dipping the bristles no more than a third of the way into your emulsion paint, then tap gently on the inside of the tin to remove excess without overloading. Position the brush close to the edge you’re cutting in and use smooth, deliberate strokes to guide the paint along the trim or junction. Keep the brush angled so the tapered edge leads the stroke, which helps form a sharp line. Thanks to Blade Technology, the brush naturally creates a crisp boundary without dragging or spattering. Work in short sections for greater control and reload the brush regularly to maintain an even application. With a bit of practice, this method produces professional-grade results without the need for tape.
A) Cleaning the Harris Ultimate Walls & Ceilings Blade Paint Brush promptly after use is key to preserving its precision and longevity. Start by removing as much excess emulsion as possible using a rag or the edge of the paint tin. Rinse the brush under warm running water while gently working the bristles with your fingers to release trapped paint. A mild soap or brush cleaner can be used to break down any remaining residue, especially near the ferrule. Avoid soaking the brush or using very hot water, as this can damage the synthetic bristles. Once clean, shake out any excess water, reshape the bristles to their original form, and lay the brush flat or hang it to dry in a well-ventilated area. Never store it bristle-down while wet, as this can deform the brush and reduce its performance over time.
A) After cleaning, it’s important to store the Harris Ultimate Walls & Ceilings Blade Paint Brush properly to preserve its shape and performance. Ensure the brush is completely dry before storing to prevent mould growth or odour. Lay it flat or hang it with the bristles pointing downwards to retain the shape of the tapered edge. If supplied, use the original case to protect the bristles from damage during storage. Avoid placing heavy objects on top of the brush or storing it in a confined space where the bristles may become bent or compressed. With regular cleaning and correct storage, the brush will maintain its precision edge across multiple projects, offering reliable results time and again.
A) Yes, while primarily intended for cutting in along walls and ceilings, the Harris Ultimate Walls & Ceilings Blade Paint Brush is also highly effective for trim work such as skirting boards, architraves, door frames, and other narrow features. Its 2-inch width provides a good balance between precision and coverage, and the finely tapered bristles allow you to reach into corners and follow the contours of detailed trim work without smudging or overpainting. It’s particularly useful for areas where masking tape would be impractical or time-consuming. The brush’s consistent paint flow and sharp edge help achieve neat finishes even along slightly irregular trim surfaces, making it an excellent all-rounder for interior decorative detailing.
A) The Harris Ultimate Walls & Ceilings Blade Paint Brush is optimised for emulsion paint on internal surfaces, so it is not suitable for oil-based or solvent-based coatings. Using it with such products may damage the bristles and reduce the precision of the tapered edge. It is also not intended for use on large, flat wall areas where a roller would be more efficient. Additionally, while the blade-shaped bristles offer excellent control, achieving sharp lines still depends on user technique, particularly in tricky areas. The brush should not be left in water or damp storage conditions, as this could lead to bristle distortion or detachment over time. Used as intended, however, the brush delivers consistently high performance for detailed emulsion painting.
A) Yes, the Harris Ultimate Walls & Ceilings Blade Paint Brush is part of Harris’ top-tier decorating range and is widely used by professional painters and decorators. Its advanced Blade Technology and NO-LOSS filament retention make it ideal for cutting in with precision and achieving crisp lines quickly and cleanly. The ergonomic handle is designed for long periods of use without causing hand fatigue, while the high-quality synthetic bristles maintain their performance across multiple projects. Its ability to deliver a near-perfect finish without the need for masking tape makes it a time-saving tool that decorators can rely on. Whether working on residential interiors, commercial spaces, or heritage refurbishments, the brush is engineered to meet the exacting standards of trade professionals.
