Producing specialist decorative finishes
This unit introduces learners to the application of specialist decorative finishes in painting and decorating, focusing on three key techniques: preparing high-quality ground coats, creating broken colour effects using acrylic and oil-based scumbles, and applying single-colour stencils. These skills are essential for producing visually appealing and durable finishes in both residential and commercial settings, enhancing the aesthetic value of interior spaces through precise craftsmanship.

Topic Overview
The City & Guilds Level 1 Diploma in Painting and Decorating is an introductory qualification designed for students who are new to the trade. It covers fundamental skills such as preparing surfaces, applying paint, and hanging wallpaper, as well as essential health and safety practices. This diploma provides a solid foundation for progressing to Level 2 or starting an apprenticeship, making it a crucial first step for anyone aiming to become a professional painter and decorator.
Throughout the course, you will learn how to select and use tools like brushes, rollers, and scrapers, and how to work with different materials including emulsions, gloss paints, and lining paper. You will also develop an understanding of colour schemes and how to achieve a professional finish. The qualification is hands-on, with practical assessments that test your ability to complete tasks to industry standards. By the end, you will be able to prepare walls, ceilings, and woodwork, apply paint evenly, and hang wallpaper without bubbles or tears.
This diploma fits into the broader construction and building services sector by equipping you with the skills needed for entry-level roles in decorating. It also emphasises teamwork, communication, and following instructions, which are vital in any construction environment. Whether you plan to work for a company or become self-employed, this qualification gives you the confidence and competence to start your career.

Assessment Guidance
Guidance for achieving higher grades
- 💡Always follow the manufacturer's instructions for product mixing, application, and drying times to ensure quality results.
- 💡Practice your scumble technique on sample boards to develop a consistent hand before working on the assessed piece.
- 💡Spend ample time on preparation; a flawless ground coat is the foundation for successful decorative finishes.
- 💡For stencilling, use low-tack spray adhesive to hold the stencil in place and apply paint sparingly with a nearly dry brush to prevent bleeding.
- 💡Tip 1: In practical assessments, focus on neatness and attention to detail. Examiners look for clean edges, no paint splatters, and smooth finishes. Take your time to cut in carefully around windows and skirting boards.
- 💡Tip 2: Know your tools and materials. Be able to explain why you choose a specific brush or roller for a job. This shows understanding and can earn you marks in oral questioning.
- 💡Tip 3: Practice health and safety throughout. Always wear appropriate PPE, set up ladders correctly, and keep your workspace tidy. Examiners note safe working habits.
Common Mistakes
Common errors to avoid in your coursework
- Rushing surface preparation, leading to imperfections that show through the ground coat.
- Applying scumble glaze too thickly, which can obscure the base colour and take too long to dry.
- Overworking the scumble glaze, resulting in a muddy, blended appearance rather than a distinct broken colour effect.
- Allowing stencil paint to bleed under the stencil edges due to overloading the brush or applying too much pressure.
- Confusing the properties of acrylic and oil-based scumbles, such as using water to thin oil-based products or vice versa.
- Mistake: Skipping surface preparation because it seems unnecessary. Correction: Poor preparation leads to paint peeling or bubbling; always clean, sand, and prime surfaces first.
- Mistake: Applying thick paint coats to cover faster. Correction: Thin, even coats dry better and reduce drips; multiple thin coats are more durable than one thick coat.
- Mistake: Hanging wallpaper without matching the pattern. Correction: Always measure and align patterns at the ceiling or a reference point to avoid visible mismatches.
