DUTCHMAN REPAIR OF WOOD FLOORBOARDS
A. This procedure includes guidance on repairing small
localized damage to wood floorboards by cutting out a
geometric piece of the board slightly larger than the
damaged area and replacing it with a piece of wood cut
and fit to match. This method of repair - called a
dutchman - enables as much of the original material to be
retained as possible.
B. This procedure may also be used for making small repairs
to wood trim and may include filling holes left from
heating or plumbing pipes.
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. A wood floor surface can be either a series of connected
planks or parquet (small wood pieces arranged in
decorative patterns). The wood used is either plain sawn
or quarter sawn. Plank flooring, the more common type,
is assembled by joining: butt joint, tongue and groove,
shiplap, doweled or spline. Wood floors are usually
secured to the under structure by countersinking nails,
blind-nailing, or screwing and plugging.
A. Wood for dutchman (match existing material to be repaired
including species, saw/grain)
B. Wood glue such as Elmer's or equivalent
3.01 ERECTION, INSTALLATION, APPLICATION
A. Remove damaged portion with hammer and chisel.
1. Cut an irregular geometrically-shaped cavity in the
wood that is slightly larger than the damaged area.
Select a geometric shape that is easy to reproduce
such as a diamond or trapezoid, but is not obvious
to the eye (a plug in the shape of a circle or
square is more apparent).
2. Bevel the edges of the cavity.
B. Fabricate a plug to match the surface cavity bevel from
matching wood stock. Make sure that the grain direction
also matches. Glue the plug into the cavity.
C. Allow the glue to dry, then plane or sand if necessary
and refinish to match surrounding floor.
