Slivers/Splinters in Hardwood Floors

What it is: Slivers and/or splinters are protruding from the surface of the floor, especially at the edges of the boards.

Cause:

• Unevenness caused by expansion, cupping, subfloor irregularities, edge crushing from expansion or grain raise from moisture.
• Damage during installation associated with nailing.Wind shake (associated with annual rings/springwood fractures).
• May tend to occur more frequently in beveled prefinished products and wirebrushed products.
•  Improper grading.

 Cure:

• If a new floor is producing fibers, not splinters, buff  vigorously with a commercial buffer and nylon polishing pad.
• For slivered bevels, shave off with a razor knife and re-stain.
• For expansion, cupping and grain raise, correct the moisture source.

For wind shake, it may be possible to repair the boards using low viscosity, CA (cyanoacrylate) adhesive (such as Super Glue). Apply the adhesive under the seam of the shake. The adhesive will wick down and hold the shake. Because it is clear and nonambering, it can even be used between coats of finish. Or, the boards can be removed and replaced.
