*** CRACKING & ALLIGATORING
Cracking is generally a result of paint againg to an excessively hard finish, most often caused by many layers of old gloss oil paint. The paint is unable to expand and contract resulting in hairline cracks which allow water to enter and seep down to the wood itself. Resulting pressure and subsequent shrinking of paint film cause the paint to curl and flake off, and expose the bare wood.
Solution: If this condition is noticed before it becomes severe, wire brushing and repainting .. If complete paint removal is necessary, always prime bare wood surfaces Oil or Acrylic Latex Primer Sealer.
