REPAIRING SCRATCHES, GOUGES, AND DENTS IN WOOD WALL ORNAMENT
A. This procedure includes guidance on repairing scratches,
gouges and dents in wood by sanding and filling with
putty as required.
B. Scratches, gouges and dents in wood wall ornament are
usually the result of an abrasive object coming into
contact with the surface of the wood member in question.
This type of damage is usually avoidable if care is taken
around wood surfaces.
C. See 01100-07-S for general project guidelines to be
reviewed along with this procedure. These guidelines
cover the following sections:
1. Safety Precautions
2. Historic Structures Precautions
4. Quality Assurance
5. Delivery, Storage and Handling
6. Project/Site Conditions
7. Sequencing and Scheduling
8. General Protection (Surface and Surrounding)
These guidelines should be reviewed prior to performing
this procedure and should be followed, when applicable,
along with recommendations from the Regional Historic
Preservation Officer (RHPO).
A. Interior wood wall ornament may include crown moulding,
picture rail, chair rail, wainscotting, base, and casing.
B. For the purpose of this procedure, repair of interior
wall ornament may also pertain to interior wood wall
covering and trim; ceiling covering, trim, and ornament;
door trim; window trim; ornamental columns and posts; and
built-in cabinets and bookcases.
C. Scratches are slight marks produced by rubbing, scraping
or tearing with something sharp or rough. Gouges are
blunt grooves or holes and are generally deeper than
scratches. Dents are depressions or hollows made by a
blow or by pressure.
B. Wood stain
C. Linseed oil putty
D. Wood filler (there are four basic types):
1. Water-mix Wood Putty: Easy to tint and fairly
resilient, but has poor moisture resistance.
2. Solvent-based Wood Filler: Not tintable, but has
many color choices. A solvent is needed to clean
any excess or spills. It is difficult to sand, but
has good adhesion and moisture resistance. It also
has a problem with shrinkage.
3. Acrylic Latex Wood Filler: Better than water-based
in adhesion, moisture resistance, and flexibility.
Apply the filler in layers to avoid shrinkage.
4. Two-part Polyester Filler: Similar to auto body
filler. It has excellent adherence and moisture
resistance with minimal shrinkage. It stains
easily, but is time consuming to prepare.
A. Putty knife to apply filler
B. Any mixing tools required for filler.
C. Steam iron and moist cloth
A. Inspect for paint that is worn, chipped, peeling,
blistered, or flaking. If any of these conditions exist
there may be moisture entering the feature. Check for
possible sources of this moisture and correct as
B. Inspect for the signs of decay and/or insect infestation
and make repairs as necessary.
3.02 ERECTION, INSTALLATION, APPLICATION
A. Carefully hand rub scratches and minor surface
imperfections with a fine grit sandpaper. Match patina
of unscratched wood by selective staining. Do not remove
more than 1/16" thickness of the material. Maintain
levelness of surface over entire width or length of wood
B. Small gouges and nail holes can be filled using linseed
oil putty. Stain the putty to match using the sediment
from the bottom of the stain can, or use universal tints.
C. For large holes, use a sandable filler. Stain to match
as above (if needed).
D. Lift dents with steam iron and moistened cloth. Moisture
will raise the grain of the wood surface and it will have
to be sanded smooth and refinished.
E. Touch-up resurfaced area during finishing so that color
and other appearance characteristics match the finish of
