Causes of cracks in wooden finishes

There are a number of different causes of cracks in wooden finishes, including:

  • Moisture
  • Thermal expansion and contraction
  • Ageing
  • Improper finishing
  • Damage

Moisture is one of the most common causes of cracks in wooden finishes. When wood absorbs moisture, it swells. If the wood is then exposed to dry conditions, it will shrink. This shrinking and swelling can cause the finish to crack.

Thermal expansion and contraction is another common cause of cracks in wooden finishes. When wood is exposed to heat, it expands. When wood is exposed to cold, it contracts. This expansion and contraction can cause the finish to crack.

Ageing is another factor that can contribute to cracks in wooden finishes. As wood ages, it becomes drier and more brittle. This can make it more susceptible to cracking.

Damage can also cause cracks in wooden finishes. If wood is struck by a sharp object, it can crack. If wood is exposed to chemicals, it can also crack.
