How to Install Vinyl Floor Trim

Vinyl floors are very common in the foyer, kitchen or bath or in any room that needs a durable and easy to clean floor. This type of floor can be designed to look like tile, stone and even hardwood. It is usually installed over a sub floor and underlayment and sometimes, over an older floor. The most common ways to trim a vinyl floor is similar to any hard surface floor. Along walls it is common to use baseboards and 1/4-round trim. Thresholds are used to transition from one floor type to another.

  1. 1

    Measure the longest wall in the room where the vinyl flooring has been installed. Cut the baseboard to fit into the corner and to end at a second corner or at the opening of a doorway. If the wall is uneven or wavy it may be a good idea to glue the moulding to the wall as well as nail it, otherwise you may have substantial gaps between the wall and moulding.

  2. 2

    Apply a bead of construction adhesive to the back of the moulding and press it firmly into the wall so that the moulding follows the contour of the wall. Nail finish nails every 12 inches along the moulding trying to hide the nail holes in the contour of the baseboard when possible.

  3. 3

    Start your second baseboard in the same corner as your first. Cut the corner end of the baseboard at a 45-degree angle. Allow extra board until you have properly fitted your first corner. Draw along the edge of the 45-degree cut to make it easier to see. Take your coping saw and cut along the pencil line removing 50 per cent of the remaining wood. This will allow you to fit the second baseboard to the contour of the first board in the corner. Make minor cuts until the board fits well. Measure carefully and cut the other end of the board to the length that you need.

  4. 4

    Measure and cut the 1/4-inch round moulding to fit along the bottom edge of the baseboard and over the edge of the vinyl floor. Round or mitre back exterior corners. Glue and nail. After installing all of the baseboard and 1/4-round trim, use a hammer and nail set to recess the finish nails into the wood. Fill the holes with wood fill and caulk along all seams, cracks and corners for a clean, finished appearance.

  5. 5

    Select the correct transition material to create a bridge between the vinyl floor and any adjacent flooring. There are transition boards and metal strips designed to smooth out and finish the floor between most flooring types. Often a transition will bridge from a low floor like vinyl to a much thicker floor like tile and hardwood. These transitions often glue and are nailed after being cut to size. Follow the manufacturer's recommendations for your transition type for best results.

Tips and warnings

  • Pre-prime and paint your baseboard and 1/4-round trim before installation. This reduces finishing time significantly and you may only need to paint over wood filled areas after the trim is installed for a clean and finished look.
