Can you plaster over artex? What you need to know before starting
Can you plaster over artex without removing it first? This is a question that homeowners across Kent and Bromley frequently ask when planning renovation projects. The straightforward answer is yes, you can plaster over artex, but like many plastering tasks, it’s not always advisable in every situation. Understanding when plastering over artex makes sense and when removal is the better option can save you time, money, and potential headaches down the line. TL;DR – Quick Summary Yes, you can plaster over artex – but only when it’s well-adhered, post-1985, and has minimal texture depth Pre-1985 artex may contain asbestos – requiring professional testing and potentially licensed removal before any work begins Professional preparation is essential – including PVA sealing, surface assessment, and typically a two-coat plastering method for best results Deep textures and damaged artex require removal – covering these creates long-term problems that cost more to fix later Budget considerations matter – plastering over costs less initially, but removal may offer better value for property developers and high-end renovations Can you plaster over artex? The complete guide The question of whether you can plaster over artex doesn’t have a simple one-size-fits-all answer. Professional plasterers in Kent evaluate multiple factors before recommending the best approach for each unique situation. These include the artex’s age, condition, texture depth, and whether asbestos might be present. For many homeowners and property developers in Bromley and throughout Kent, plastering over artex represents an efficient renovation solution. It saves time compared to complete removal and delivers the smooth, contemporary finish that modern buyers expect. However, taking this approach without proper assessment can lead to disappointing results and costly remedial work. The key to success lies in understanding when covering artex is appropriate and when removal becomes the wiser investment. This comprehensive guide examines both scenarios to help you make an informed decision for your specific project. What is artex and why was it so popular? Artex is a textured coating material that dominated British interior design from the 1960s through the 1980s. Composed of gypsum plaster mixed with additives to create various decorative patterns, it offered an affordable way to add visual interest to ceilings and walls. The material could be applied in numerous patterns including stipple, swirl, and peaked designs. During its heyday, artex served multiple practical purposes beyond aesthetics. It effectively concealed imperfections in plasterwork, provided some acoustic dampening, and was considered modern and stylish. Many homes built or renovated during this period feature artex in living rooms, bedrooms, and hallways. The material’s popularity stemmed from its cost-effectiveness and ease of application compared to traditional ornamental plastering. Property developers could finish homes quickly whilst giving them a distinctive character. This explains why millions of UK properties still feature artex ceilings and walls today, particularly in areas like Kent where housing stock includes many properties from this era. The asbestos concern with older artex Here’s what every homeowner and contractor must understand: artex manufactured before 1985 may contain asbestos fibres. Chrysotile (white asbestos) was commonly added to artex formulations to improve strength and fire resistance. This creates serious health and safety implications when renovating older properties. You cannot determine whether artex contains asbestos simply by looking at it. The only reliable method is professional laboratory testing of samples. If your property was built or renovated before the mid-1980s, you must assume artex potentially contains asbestos until testing proves otherwise. Disturbing asbestos-containing artex releases harmful fibres into the air, posing significant health risks including lung disease and cancer. UK law requires licensed professionals to remove asbestos-containing materials in most circumstances. Simply plastering over confirmed asbestos artex, whilst potentially permissible if done without disturbance, doesn’t eliminate the long-term liability. Professional plasterers in Tunbridge Wells and across Kent understand these regulations thoroughly. They can arrange proper testing and, if necessary, coordinate with licensed asbestos removal contractors before proceeding with plastering work. This protects both your health and your legal position as a property owner or developer. When plastering over artex makes sense Several scenarios exist where applying plaster directly over artex represents the most practical and cost-effective solution. Understanding these situations helps homeowners and developers make informed decisions that balance quality, budget, and timeline considerations. The decision ultimately depends on three primary factors: the condition of existing artex, the type and depth of texture present, and your specific project constraints. When these factors align favourably, plastering over artex delivers excellent results that can last for decades. Condition of the existing artex surface Well-adhered artex provides a suitable substrate for plastering when it remains firmly attached to the underlying surface. Before proceeding, professional plasterers conduct a thorough assessment by pressing various areas and listening for hollow sounds that indicate detachment. Firmly bonded artex with no signs of moisture damage or crumbling passes this critical test. Conversely, artex showing signs of deterioration requires removal rather than covering. Loose areas, flaking sections, or water-stained artex indicates underlying problems that plastering over will simply conceal temporarily. These issues inevitably resurface, causing the new plaster to crack or detach within months or years. The substrate beneath the artex matters equally. If applied over old plasterboard or lime plaster in good condition, covering becomes viable. However, artex applied over already-failing surfaces compounds the problem. Professional assessment distinguishes between cosmetically poor artex that’s structurally sound and genuinely compromised surfaces requiring complete renovation. Type and depth of artex texture Not all artex patterns present equal challenges when plastering over them. Fine stipple textures typically measure 1-3mm in depth and can be successfully covered with proper preparation and a two-coat plastering system. These shallow textures allow plasterers to build up a level surface without excessive material application. Medium swirl patterns, measuring 3-6mm deep, require more substantial preparation and thicker base coats. Whilst still manageable, these patterns demand greater skill and material to achieve a perfectly smooth finish. Experienced plasterers can handle these textures, but the process takes longer and costs more than covering fine stipple. Deep artex patterns present significant challenges: Peaked or ‘artex mountain’
