Inspect your floor and decide on an installation method
If you have an existing vinyl floor that's not coming loose and the underlying floor is solid and flat, you can glue new vinyl directly over it as we show in this article. We don't recommend tearing out old vinyl floors because many contain asbestos, which can be hazardous to your health.
If your existing floor is wood planks, loose or deteriorated vinyl, or is in bad shape, you'll have to cover it with a layer of 1/4-in. plywood. Make sure you use special underlayment plywood recommended for use under vinyl floors and follow the manufacturer's instructions for installing it. This method raises the height about 3/8 in. You may have to cut off door bottoms and use special transition strips at openings.
If you plan to install vinyl over concrete, check for excessive moisture by gluing down a 3 x 3-ft. piece of vinyl and taping the edges. After 72 hours, try to pull up the vinyl. If it comes up easily, there's too much moisture in the concrete to install vinyl.
Next measure your floor and draw a simple sketch with dimensions. Take the sketch along when you shop for flooring. The salesperson will help you figure the quantity to order. Also order embossing leveler, adhesive, seam sealer (if necessary) and transition pieces. See “Buying Vinyl” for more information.
Vinyl flooring ranges in price from about 60¢ to $3 or $4 per square foot plus $50 to $100 for floor leveling compound and adhesive.
Most vinyl flooring is available in 12-ft. widths so you can cover a wide area without creating seams. However, some of the higher quality vinyl floors are stiffer, so they're available only in 6-ft. or 6-ft. 4-in. widths for easier installation. Stiffer vinyl is more difficult to install than more flexible vinyl and you'll have to make more seams. If you fall in love with the pattern on one of these stiffer vinyls, hire a pro to install your flooring.
There are two installation options for vinyl floors. Most require a full spread of adhesive as shown in this article. This is a time-tested method that guarantees good results. Another type of vinyl flooring allow you to apply glue only to the perimeter. This type is slightly more forgiving of imperfections in the existing floor, but it still requires careful attention to the installation details.
Careful floor prep is the key to a great-looking job
Start by prying loose the base shoe molding and thresholds or carpet strips at the doorways. If you don't have base shoe, plan on adding it after you install the floor to cover the edges of the vinyl.
Photo 1 shows how to cut off the bottom of door trim and jambs so the new flooring will slide under them. This is a lot easier than trying to cut the vinyl to fit around them. Photos 2 and 3 show how to fill the embossed pattern and minor indentations in the old floor to prepare it for vinyl. After the first coat dries, inspect the floor with a raking light to make sure it's perfectly smooth. Trowel on another coat of filler if necessary.
Make a paper template for a perfect fit
Pick up masking tape and a roll of rosin paper (about $8 at home centers and lumberyards) and use them to assemble a paper template of the floor. Photos 4 – 6 show how. Overlap and tape the seams. Cut out triangles every 3 ft., and tape the template to the floor to keep it from shifting while you draw the lines. You can use any straightedge to transfer the lines to the paper, as long as you use the same one to then transfer the lines to the vinyl. We bought two inexpensive 3-ft. aluminum rulers and cut one into shorter lengths to fit short wall sections.
If your room includes curved or irregular shapes, use a compass rather than the straightedge to scribe the line. Hold the compass points at a right angle to the surface you're scribing and keep the compass setting the same when you scribe the line onto the new vinyl.
Photo 6 shows how to mark around doorjambs and trim. It's helpful to mark the edges of the trim on the template. But be sure to indicate that these are actual rather than scribed lines by putting “Xs” on these marks (Photo 6). Then transfer these lines directly to the vinyl rather than scribing them with the straightedge.
Transfer the template to the vinyl
Find a large enough area, like a basement or garage floor, and sweep it thoroughly before you roll out the new vinyl. Then position the paper template on the vinyl. Now you'll have to make some decisions. If your vinyl has a symmetrical pattern like ours—simulated tile, for example—make sure the template is parallel with the “grout” lines on the longest, most conspicuous wall. Also shift the template until the border tiles are equal (Photo 7).And finally, if you're planning a seam that has to fall in a particular spot—we placed a seam in the opening to the next room—then make sure there's a grout line or other pattern at this location to help hide the seam.
When you're satisfied with the alignment, tape the template to the vinyl through the triangle cutouts, and also set a few heavy items on it to keep it from shifting. Then transfer the marks from the template to the vinyl (Photo 8).Use a pencil or a pen, not a marker. In areas that will be covered by base shoe or moldings, cut about 1/8 in. inside the line to allow a little space between the wall and the vinyl (Photo 9).Cut on the line in areas that won't be covered. Leave a few extra inches of vinyl at the seam location. You'll need this extra material to double-cut the seam.
Fit the vinyl and spread the adhesive
Start by sweeping the old floor. You can't be too careful here. Any little speck of dirt will show through the new vinyl floor. Roll the new vinyl and carry it into the room. Get help if you have an extra large piece. Support the vinyl carefully as you unroll it so it doesn't crease or kink. It should fit perfectly. Photo 10 shows how to fit the vinyl under door trim. Trim the vinyl with your hook blade in areas where it's too tight.
Next plan a gluing strategy that will allow you to glue down the flooring in two nearly equal sections. When you're satisfied with the fit and have a gluing plan, set a few heavy items on the half you'll be gluing last to keep the vinyl from shifting. Then roll back the vinyl to the midpoint and spread glue under it (Photo 11).
First trowel the adhesive around the perimeter, then fill in the middle with an even coat (Photo 11).Don't leave any globs. Leaving too much adhesive is a common mistake that will result in glue bubbles under your new floor. Trowel the glue in a straight line along the rolled-back vinyl. Avoid double- coating this area when you trowel the second half. Let the adhesive set for the recommended time, usually about 20 minutes, before you rolling the vinyl back over it (Photo 12).
Glue down the flooring
Photo 12 shows how to lay the first half of the vinyl on the adhesive. Keep a bucket of water and a rag available to clean up all extra adhesive immediately. It's difficult to remove once it starts to dry. Roll the vinyl as soon as possible after gluing it down. Use a rolling pin on small floors (Photo 13) or rent a special floor roller for large floors (about $15 per day). Watch for bubbles and work them toward the edges if possible. If they remain after you've finished rolling, be patient; they'll probably disappear in a day or two. Next roll the unglued section of vinyl back onto the completed half and repeat the gluing
and rolling steps.
Finish the job by reinstalling the base shoe and installing new threshold or transition moldings at doors and openings to other rooms. Use matching caulk to seal edges that aren't covered by base shoe.

If you have to make a seam, use this “double-cut” method
There are several methods for cutting and assembling seams. Check with the manufacturer of your flooring to see which one it recommends. The double-cutting method we describe here is an easy way to get a good fit between two pieces. But be sure to align the two pieces exactly before cutting through them. Then use a sharp new blade and firm pressure to cut entirely through both layers of vinyl in one pass.
The photos on the right show the process. If your flooring has a repeating pattern, make sure to align it correctly. Notice that we completed the floor installation on one side of the seam before making the template for the other half.
Removing the underlying vinyl strip (Photo 3) may remove adhesive as well. Use the narrow edge of your notched trowel to spread additional glue over this area before assembling the seam. Be careful to avoid getting adhesive on the edges that will be joined. Follow the instructions on the package to apply the seam sealer.
