Wood flaking is a phenomenon in which the top layers detach or separate from the underlying wood. This phenomenon can be the result of several factors, including humidity, temperature changes, aging of the wood, improperly applied coatings, or other harmful influences. But how to renovate correctly flaking wooden surfaces?
Causes of wood flaking
- Humidity: Frequent exposure of wood to high humidity or contact with water can cause moisture to soak into the wood, leading to flaking of the top layers.
- Temperature changes: Frequent transitions between temperature extremes can cause the wood to expand and contract, eventually causing peeling/flaking.
- Aging: Wood naturally wears over time and aging can cause the top layers to peel off or separate from the underlying wood.
- Improperly applied coatings: Applying coatings, such as paints or varnishes, to improperly prepared or humid wood can cause the coatings to peel off and cause peeling/flaking.
- Physical damage: A strong impact or pressure on the wooden surface can also cause peeling of the upper layers.
Renovation steps for peeling/flaking wooden substrates
- Clean and prepare the substrate: Remove the protruding parts of the wood and clean the substrate. The latter should be dry and free of dirt or coatings.
- Repair damaged parts: Fill any cracks or minor impairments with JUBIN Akrilin wood filler and follow the instructions for use.
- Sanding: Gently sand the substrate of the wood to remove rough edges and ensure a smooth substrate.
- Apply wood coating: Apply the appropriate type of wood coating (transparent – JUBIN Lasur or varnish – JUBIN Decor Universal) according to the instructions for use. Using the correct products for wood will help protect the wood and prevent further peeling/flaking.
