    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Scratch coat is applied evenly with visible scoring to provide a mechanical key.
    • Stop beads are cut square, fixed plumb and level, and securely attached.
    • Backing plaster is applied flush with the stop beads, with no hollows or excessive thickness.
    • Finish plaster is trowelled smooth, free from trowel marks, and feathered into the beads.
    • Work area is left free of debris, tools cleaned, and waste disposed of in accordance with site rules.
    • Correct measurement and cutting of stop beads to fit between boundaries, with neat mitred corners if applicable.
    • Consistent mix ratio of plaster to achieve workable consistency without slumping or cracking.
    • Application of scratch coat with appropriate thickness (e.g., 10-12mm) and even combed key.
    • Leveling and straightening of backing plaster using a straight edge to fill the bead depth.
    • Double coating of finish plaster with troweling technique to eliminate trowel marks and achieve a polished finish.
    • Proper cleaning of tools and disposal of waste, leaving the area free of debris and splatter.
    • Award credit for demonstrating correct mixing ratios and consistent application of the scratch coat, ensuring full coverage and keying for the next layer without over-troweling.
    • Award credit for accurately measuring, cutting with tin snips, and securely fixing internal stop beads, ensuring they are plumb and level to provide true margins for plastering.
    • Award credit for applying lightweight backing plaster evenly and to the required thickness, feathering into the beads and ruling off to a flat plane with a straightedge.
    • Award credit for applying two separate coats of lightweight finish plaster, with the first coat filling any minor imperfections and the second achieving a polished, blemish-free surface through controlled troweling.
    • Award credit for leaving the work area swept clean, tools washed, and all waste disposed of appropriately, demonstrating adherence to health and safety protocols.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Practice maintaining a consistent trowel angle and pressure to avoid excessive sanding later.
    • 💡Check that stop beads are plumb and level before plastering, as they guide the final surface.
    • 💡Plan the sequence of work to minimize cleaning time and avoid contamination between coats.
    • 💡Always check the background for suction and dampen if necessary before applying the scratch coat to ensure proper adhesion.
    • 💡Use a spirit level and straight edge frequently when fixing beads to guarantee accurate alignment.
    • 💡Work methodically when applying finish coats, allowing the first coat to stiffen slightly before applying the second for better control.
    • 💡Keep a clean water bucket and sponge at hand to clean tools and edges, maintaining a professional finish.
    • 💡In practical assessments, always present your work neatly: ensure beads are clean and free of plaster residue, and that the plaster surface is free from trowel marks and undulations.
    • 💡Read the assignment brief carefully to confirm the required plaster thicknesses and finish specifications; if a sample panel is provided, replicate its standard precisely.
    • 💡Time management is critical: set out your materials and tools beforehand, and plan the sequence to avoid delays between coats, ensuring each layer is still workable before application.
    • 💡During supplementary written questions, link your answers to health and safety legislation such as COSHH for plaster dust and manual handling regulations when lifting bags of plaster.
    • 💡Tip 1: Focus on accuracy over speed. Examiners award marks for correct measurements, straight lines, and neat finishes. Rushing leads to mistakes – take your time to set out work properly.
    • 💡Tip 2: Keep your workspace tidy. A clean area shows you are organised and safety-conscious. It also prevents accidents and makes it easier for assessors to see your work clearly.
    • 💡Tip 3: Practice using tools correctly before the assessment. Know how to hold a saw, trowel, or brush properly. Using tools the right way improves control and quality of your work.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to dampen the substrate before applying the scratch coat, leading to poor adhesion.
    • Incorrectly aligning stop beads, resulting in uneven plaster thickness.
    • Over-mixing the plaster or using the wrong water ratio, causing premature setting or weak finish.
    • Using too much water in the plaster mix, leading to weak bonding and surface dusting.
    • Incorrect positioning of stop beads, resulting in uneven reveals or non-plumb edges.
    • Over-troweling the finish coat, causing the plaster to become polished and impermeable, which may hinder subsequent decoration.
    • Failing to protect adjacent surfaces from plaster splatter, requiring extra cleaning.
    • Failing to dampen the background before applying the scratch coat, causing rapid water absorption and poor adhesion, leading to a weak bond.
    • Fixing stop beads with insufficient nails or adhesive, resulting in movement during plastering; also, not cutting beads accurately causing gaps or overlapping at corners.
    • Overworking the backing plaster while it is setting, which can disrupt the crystal structure and weaken the final set, or applying it too thinly over the scratch coat, reducing mechanical key.
    • Applying the finish plaster before the backing coat has adequately cured, trapping moisture that may cause blistering, or attempting to polish too early, dragging the surface and creating roughness.
    • Neglecting to cover adjacent surfaces or failing to clean splatters promptly, leading to contamination and extra remedial work, and not segregating waste materials as per site regulations.
    • Misconception: 'You don't need to measure twice – just cut once.' Correction: Always measure twice and check your markings before cutting. A single mistake can waste materials and time, which is costly on a real site.
    • Misconception: 'Safety gear is optional for small tasks.' Correction: PPE like safety glasses, gloves, and hard hats must be worn at all times in workshops, even for quick jobs. Accidents can happen in seconds.
    • Misconception: 'Mortar should be very wet to stick better.' Correction: Mortar needs the right consistency – not too wet or dry. Too much water weakens the bond and causes bricks to slip. Follow the mixing instructions carefully.
