Artex ceilings were a popular decorative feature in homes throughout the UK, particularly in the 1970s and 1980s. While they add texture and character to a room, over time, cracks can appear, causing concern for homeowners. Understanding the reasons behind these cracks can help determine whether they are cosmetic or a sign of a more serious issue.
Natural Settlement and Structural Movement
One of the most common reasons Artex ceilings develop cracks is natural settlement and structural movement. Buildings expand and contract due to temperature changes, humidity levels, and natural shifts in the foundation. These subtle movements can cause minor cracks in the Artex, particularly in older properties where the structure has had more time to shift.
Moisture and Water Damage
Moisture is another leading cause of cracking in Artex ceilings. Water leaks from a roof, plumbing issue, or condensation buildup in poorly ventilated areas can weaken the ceiling material and cause it to crack or even peel away. If water damage is suspected, it is important to identify and fix the source of the moisture before repairing the ceiling.
Poor Application or Ageing Material
The quality of the original Artex application can also play a role in cracking. If the mixture was applied too thickly or without proper bonding to the ceiling, it may become brittle over time and develop cracks. Additionally, as Artex ages, it naturally becomes more fragile, making it more susceptible to damage from minor impacts or general wear and tear.
Vibrations and Movement in the Property
Everyday activities, such as closing doors forcefully, heavy foot traffic on upper floors, or even nearby construction work, can create vibrations that lead to small cracks in an Artex ceiling. In some cases, covering with plaster, fixing loose plasterboards or securing ceiling joists can help reduce movement and prevent further cracking.
How to Repair Cracked Artex Ceilings
If the cracks in your Artex ceiling are purely cosmetic, they can often be repaired using a flexible filler or reapplying a matching textured coating. For more severe cracks, professional assessment may be required to ensure there are no underlying structural issues. If the ceiling contains old Artex that may include asbestos, it is important to seek expert advice before attempting any repairs or removal.
Understanding why Artex ceilings crack can help homeowners take the right steps to prevent further damage and maintain the appearance of their interiors. Regular maintenance, proper ventilation, and addressing any moisture issues promptly can all help prolong the life of an Artex ceiling.
