A construction crew is repairing a damaged Glued Laminated Timber (Glulam) beam in a commercial building. The damage consists of a deep gouge on the face of the beam. According to best practices, which of the following is the most appropriate method for repairing this type of damage?

  1. AFill the gouge with standard wood putty and paint over it.
  2. BClean the gouge and fill it with an epoxy-based wood repair compound, ensuring proper adhesion and finish.
  3. CRemove the damaged area and splice in a new section of Glulam using mechanical fasteners.
  4. DIgnore the gouge, as cosmetic damage to Glulam does not affect its structural integrity.
Show answer & explanation

Correct answer: B. Clean the gouge and fill it with an epoxy-based wood repair compound, ensuring proper adhesion and finish.

For deep gouges or other non-structural surface damage to Glulam, an epoxy-based wood repair compound is the most appropriate solution. It provides a durable fill, maintains the aesthetic, and does not compromise structural integrity if applied correctly.

Why the other options are wrong

  • A. Standard wood putty is typically not durable enough for deep gouges in structural members and may not adhere well.
  • C. Splicing in a new section is a major structural repair, typically for severe damage or section loss, and requires engineering design, not just for a gouge.
  • D. While a minor cosmetic blemish might be ignored, a deep gouge can compromise the protective finish and potentially expose the wood to moisture or further damage, and should be addressed.

Glulam Cosmetic Repair

Methods for addressing surface imperfections or minor damage on Glued Laminated Timber beams that do not compromise structural integrity.

  • Epoxy-based fillers are common for gouges and checks.
  • Repairs should match the aesthetic and provide protection.
  • Structural damage requires engineering review and specialized repair techniques.

Memory trick: Gouges on Glulam? Epoxy's your friend, for a strong and smooth end.
