🎯 Role Definition

A Plasterer applies, repairs and finishes plaster, render and related materials on interior and exterior surfaces to produce smooth, durable and decorative finishes. This role requires expertise in plaster mixing and application (gypsum, cement, lime, and synthetic renders), proficiency with hand and power tools, safe use of scaffolding and access equipment, and the ability to read drawings and specifications. Plasterers work across new-build construction, renovation and restoration projects, delivering high-quality skim coats, decorative mouldings and weatherproof external render systems while ensuring compliance with building codes and client standards.

Core Responsibilities

Primary Functions

  • Prepare and inspect surfaces by removing old plaster, paint, grease, or debris, ensuring substrates (lath, masonry, drywall, concrete) are sound and correctly primed before plaster application.
  • Accurately measure and cut lath, gypsum board and backing materials to specification, align joints and install temporary supports or battens for render and plaster work.
  • Mix plaster, cement render, lime putty, gypsum-based plasters and proprietary systems to the correct consistency using hand tools and mechanical mixers, following manufacturer ratios and order specifications.
  • Apply base coats (scratch and brown coats) using hand trowels, hawks, floats and mechanical sprayers to achieve proper bond, thickness and cure conditions for multi-coat systems.
  • Perform skim coating and finishing operations to produce seamless, flat, and paint-ready interior surfaces, including feathering and sanding to hide joints and imperfections.
  • Install metal bead, stop, corner profiles and control joints to protect edges, create clean lines and ensure long-term durability of plastered corners and reveals.
  • Apply external render systems (monocouche, silicone, acrylic renders) with consistent texture, ensuring weatherproofing, adhesion and correct curing for facade performance.
  • Carry out patch repair of cracked or damaged plaster, matching textures and finishes to existing surfaces for renovations and conservation projects.
  • Execute specialty decorative plasterwork, moulding, cornice installation and reproduction of ornamental features using moulds, castings, and hand-sculpting techniques where required.
  • Use spray-plastering equipment to apply gypsum or cement-based plasters on larger surfaces, calibrating machines and adjusting work methods to maintain consistent coverage and finish quality.
  • Interpret architectural drawings, specification documents and plastering schedules, coordinating with project managers and other trades to meet design intent and delivery milestones.
  • Perform quality control inspections throughout the plastering process, checking thicknesses, flatness tolerances, bond integrity and final appearance against standards and client expectations.
  • Prepare work areas, erect and safely use scaffolding, mobile towers and fall-protection systems to access ceilings, high walls and exterior facades while maintaining site safety protocols.
  • Apply primers, bonding agents, water repellents and crack-bridging membranes as specified to ensure adhesion, flexibility and longevity of plaster and render systems.
  • Maintain accurate material usage and labour records, report waste and manage on-site stock to optimize job costs and reduce rework.
  • Communicate clearly with clients, site managers and trade contractors to clarify scope, recommend solutions for substrate issues, and provide guidance on finishing schedules.
  • Troubleshoot adhesion failures, damp-related issues and cracking; recommend remedial actions such as substrate repair, chemical treatments or revised detailing to prevent recurrence.
  • Follow manufacturer technical data sheets (TDS) and Health & Safety data sheets (SDS) for all products used, ensuring correct storage, mixing, and disposal of materials.
  • Mentor apprentices and trainee plasterers, demonstrating best practices in mixing, application, finishing and safe equipment operation.
  • Ensure projects meet regulatory requirements and building codes related to fire protection, acoustic performance and thermal bridging where plaster systems are part of compliance.
  • Conduct final inspections with clients or site supervisors, address punch-list items, and deliver completed, cleaned and protected plastered surfaces ready for decoration.

Secondary Functions

  • Assist with estimating material quantities, labour hours and scope definitions for quotes and tender submissions.
  • Maintain and service hand tools, power tools and plaster pumps, scheduling repairs and replacements to minimize downtime.
  • Keep work areas tidy, manage waste disposal and recycling of packaging, and return surplus materials to yard stock when practical.
  • Log daily progress and communicate schedule impacts to supervisors to support site coordination and timely handover to finishing trades.
  • Participate in toolbox talks, safety briefings and continuous improvement meetings to share lessons learned and adopt safer, more efficient methods.
  • Support heritage restoration projects by researching original plaster compositions and selecting compatible repair materials.
  • Coordinate with painters, electricians and joiners on sequencing of penetrations, trims and final sealing to avoid rework.
  • Assist sales/operations teams by preparing before-and-after photos, progress reports and material samples for client presentations.
  • Contribute to company training materials and standard operating procedures for plaster application and quality control.
  • Monitor weather and environmental conditions, advising on protection strategies to ensure proper curing and prevent freeze/thaw or rapid drying issues.
