Rated 4.5 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by Great looking Moulding. Easy to work with I purchased this for my media room in the basement. I was looking for an upgrade of what was down there, but didn't want to spend tons of $$. This moulding is easy to cut and paint. October 8, 2013
Rated 4.0 out of 5.0 by Very good product for the price The broads are very attractive and a fraction of the cost of actual wooden boards of similar size and design. The down side of the product is that because they are a composite, they have very smooth surface making painting difficult. Unless you intend to use a spray gun, plan on two to three coats depending on the color paint you are using. August 4, 2015
Rated 5.0 out of 5.0 by Great base board This base board is great looking and easy to use. Narrow profile works well with our door frames. Easy to cut and holds paint well. Excellent price for this product! May 12, 2015
Rated 4.0 out of 5.0 by Nice looking baseboards These baseboards are very nice especially for the price. I would recommend especially if you want to add a more distinguished look by getting baseboards taller than what you currently have. We went from 3 1/2 inch boards to these and couldn't be happier with the result. February 5, 2014
Rated 5.0 out of 5.0 by simple wide baseboard This baseboard was just what I needed to finish walls and new flooring, it was easy to cut and apply. I had it delivered because I do not have an 8 ft length in my car to transport it myself. June 16, 2015
Rated 5.0 out of 5.0 by Good Value Because it is a composite material this base moulding is always straight with no bows or warping. Cuts cleanly and is easy to work with. October 28, 2014
Rated 2.0 out of 5.0 by Not for High Moisture or High Humidity Areas As an amateur woodworker, I don't understand the popularity of MDF. It is basically compressed fiberboard, with a huge amount of glue (that's why it weighs more than wood). I purchased a small run of this baseboard to replace one section in a bathroom. Eventually I tore it out and replaced the section with wood, which is what the rest of the baseboard was. MDF expands and contracts like crazy in response to moisture levels. The most noticeable problem was where a joint was made. If you are committed to using MDF, I would recommend that you prime it thoroughly (both the back and the front facing sides) with a good oil-based primer. Then paint it. You want to seal all the points where any moisture can creep in and cause it to swell like a sponge. I suppose if you do this you will be okay with MDF baseboard, but for my money it's easier to bump up to the quality of solid wood and pay the extra dollars. March 22, 2014
Rated 5.0 out of 5.0 by Base moulding was what we were looking for. Just what we were looking for! Arrived in good condition, no damage. April 14, 2015
