    What Is The Purpose Of Quarter Round?

    As the name implies, quarter round molding is a convex molding that is one-quarter of a round piece of wood. It is always seen where the floor meets the drywall. Also, you can see it staying at the bottom along the baseboard.

    Although you might think of it as a decorative element, in fact, it is typically used to hide any gaps between the baseboard and the floor. The gap is not only unaesthetic but also easy to heap up dust, debris, and dirt in it. And it is quite hard for you to clean up. You may ask why there is a gap between the floor and the drywall all the time. Couldn’t all these gaps be filled in when building the flooring? The answer is no. Leaving a vertical 1/2-inch gap at the floor, it would allow for floor and wall expansion. So it wouldn’t end up cracking the drywall. And this also helps prevent moisture that would soften the floor wood. Therefore, the main purpose of the quarter round must be to protect the gap between the surface of the floor and its adjoining wall.

    Another reason to install a quarter round molding is for aesthetic reasons. Because of the reason mentioned above, you have to leave gaps between the floor and drywall and it is unaesthetic at all. In this case, the quarter round molding would be the best remedy surely. It would hide the gaps and be a transition between the floor and walls.

    Is It Necessary To Install A Quarter Round On Baseboard?

    The purpose of baseboard installation is more than aesthetic. It has the same function as the quarter round molding–to protect the floor expansion gap. If the gap between the wall and floor is not so wide, maybe only using a quarter round is enough. But if the gap is wide, and the lower part of the wall is defective, you would need to use the baseboard to protect the wall. Installing baseboard or quarter round entirely depends on the with of the gap. However, the baseboard often finished off with an additional quarter round in some home improvements. That means to combine baseboard and quarter round. Why? Because sometimes there are still gaps between the floor and baseboard. At this time, the quarter round is applied to cover the gap between the bottom of the baseboards and the floor. 

    Therefore, installing a quarter round on baseboard is not necessary unless there is still a gap between your baseboard and the floor. But there’s also a situation where you want to use quarter round just as decoration. It would provide a finished look with the baseboard. Whether you use quarter round that matches your floor or baseboard, it will add some sparkle to your house.

    What Materials Pair With Quarter Round

    The quarter round comes in a variety of sizes and materials. Generally, the average quarter round measures up to 7 feet long. Its height and width are made of pieces of about 3/4 inches. The main kinds of construction of quarter round are as follows: hardwood, softwood, engineered wood, PVC, and Medium-density fibreboard.

    Quarter Round Wood Molding

    The quarter round of wood material is the most common. Hardwood quarter round molding, including oak, ash, and walnut, could be painted to match the baseboard. Or you can choose one that matches the color of your floor.

    PVC Quarter Round Molding 

    This kind of material has good performance in resisting moisture, termite, and split. Its original color is white and it can also be painted or stained. If you would like to match it with the white color baseboard, you don’t have to paint it. The downside of the material is that it is not very durable and may be sunken on impact.

    Medium-density Fibreboard Quarter Round Molding

    This material is a mixture of resin and sawdust. It is more stretchable and flexible than wood. If there are plenty of uneven gaps between your baseboard and floor, this would be the best option. But it doesn’t stain well as the wood and PVC.

    How To Install Quarter Round On Baseboard?

    • Step1: Firstly, measure each wall that you would like to install the quarter round molding. Then try to fit the quarter round to the baseboard and make the marks. After marking, you can begin to cut the molding into equal quarters. Make your first cut, then reverse the saw to cut 45-degrees for the other end of the trim.

    Tips: When fitting the inside corner, you need to measure the entire of the wall at first. Then cut the quarter round into suitable length to attach to the baseboard tightly. For the outside corner, put the piece of quarter round across the wall. Make the ends of two piece of quarter round to fit just right.

    • Step2: Polish the side of the quarter round that would attach to the baseboard with the sandpaper. Also, use sandpaper to brush the baseboard to be more smooth as well to allow them to bond better.
    • Step3: There are two ways to make quarter round attach to the baseboard. One is using the adhesive to form a bond between quarter round and baseboard. Another is to finish the work with nails. It is no doubt that the first way would be easier. You just have to apply adhesive to the quarter round and then align the line with the baseboard. Hold the quarter round in the proper place to make them attach firmly. If you want to install the quarter round with nails, you would have a lot of work to do. You have to repeat Step1–measure, cut, and test fit. Then Use the hammer and nails to attach the molding to the baseboard. Make sure both sides of the quarter round fit tightly to the baseboard and floor. Then drive each nail almost flush with the quarter round and sink the head beneath the surface of the quarter round. Use putty to cover the nail holes and you’ve done.
