Medium-density fiberboard (MDF) has a ton of useful applications,
but as a finished flooring material?
About five years ago, we needed a cheap "temporary" finished flooring
solution in our upstairs, 1,200-sq.-ft. addition. MDF isn't as cheap as it was
then, however. Now it runs about $30 per sheet. The idea was to use MDF until
we could afford something better (we called it our "five-year" floor).
Well, five years down the line (and no sign of new flooring in sight), here's
how the MDF is holding up (photo below).
We've found that using cheaper materials is OK if you're prepared
to put in A LOT more labor to make them look finished. That was definitely the
case with the MDF floor. We glued and screwed down 4 x 8-ft. sheets of MDF
throughout our living room, office, dining room and kitchen. We countersunk the
screw heads but left them exposed (but you could fill them). We also installed
½-in. aluminum channels between the sheets for decorative purposes and to allow
for expansion and contraction (we have radiant in-floor heat). We sanded the
floor and put three to four coats of polyurethane on it. If you choose to use
MDF as flooring, shop around at different lumberyards and home centers. You'll
find that it comes in many different shades of brown, yellow and tan.
— Less expensive than other flooring materials.
— Easy to work with.
— Surprisingly stable and solid.
— Looks good, feels good underfoot and has held up better than
expected (especially in the lower-traffic areas).
— Has a monolithic look similar to concrete but with the warmth
and softness of wood.
— Emits potentially harmful fumes (until sealed).
— Swells after contact with water or oil (right through many coats
of sealer, so we covered the kitchen MDF with cork a couple of years ago).
— Scratches easily (especially when you're scraping dining room
chairs over it constantly).
— Every run of MDF is a different color and texture. Buy enough
the first time to avoid variations.
— It was hard to apply the poly in place. The MDF absorbed it
unevenly and created an uneven finish. The next time around, we'd spray the
sheets with at least one coat of sanding sealer to seal the pores before
— Not good in high-traffic areas or where water will be a problem.
