Removing the Damaged Plank When It's Against the Wall

Replacing a vinyl plank that sits against a wall is harder than replacing one in the middle of the floor because you cannot slide it out sideways. You will need to cut the plank lengthwise into two pieces, remove each piece separately, and then install a new full plank in its place. The wall does not have to come down — you are just working around it.

Start by identifying exactly where the plank ends and the wall begins. Use a utility knife to score a straight line down the length of the damaged plank, about 2 to 3 inches from the wall. This line should run parallel to the wall and divide the plank into a thin strip (the part closest to the wall) and a wider piece (the part toward the center of the room). Score the line several times until you cut through the wear layer and into the core.

Once you have scored the line, use a pry bar to lift and remove the wider piece first. Start at one end and work your way along the length, prying gently upward. Vinyl planks are glued down, so expect some resistance. After you remove the wider piece, go back and remove the thin strip that remains against the wall. This strip is usually easier to peel away once the main plank is gone.

Key Takeaways

  • Cut the damaged plank lengthwise into two pieces so you can remove it without moving the wall or baseboard.
  • Remove the wider piece first by prying it up from one end, then remove the thin strip that remains against the wall.
  • Clean off all old adhesive from the subfloor before installing the new plank, or the new plank will sit uneven.
  • Slide the new plank into place from the side, then press it down firmly and let the adhesive set for at least 24 hours before walking on it.
  • If the wall is not perfectly straight, you may need to scribe and cut the new plank to fit the wall's shape.

Cleaning the Subfloor and Removing Old Adhesive

After both pieces of the damaged plank are out, you will see old adhesive stuck to the subfloor. This adhesive must come off, or the new plank will rock and feel hollow underfoot. Use a plastic scraper or old credit card to scrape away as much adhesive as you can by hand. Work at a low angle so you do not gouge the subfloor itself.

For adhesive that will not scrape away, use a heat gun set to medium temperature. Hold it 6 to 8 inches above the adhesive for 30 to 60 seconds until the adhesive softens, then scrape again. Do not use a heat gun on vinyl planks themselves — the heat can warp them — but it is safe to use on the bare subfloor. Once the subfloor is clean and smooth, wipe it down with a damp cloth and let it dry completely before you lay the new plank.

Measuring and Cutting the New Plank to Fit the Wall

Walls are rarely perfectly straight, so the new plank may not fit flush against the wall without some trimming. Measure the distance from the wall to the edge of the adjacent plank at three points: the top of the space, the middle, and the bottom. If all three measurements are the same, the wall is straight and you can cut the plank to a straightforward width. If the measurements vary, the wall is bowed or uneven, and you will need to scribe the plank to match the wall's shape.

To scribe a plank, use a compass or a scribe tool set to the largest gap between the wall and the plank. Place the pointed end of the compass against the wall and run it along the length of the plank while holding a pencil in the other end. The pencil will draw a line that matches the wall's contour. Cut along this line with a jigsaw, and the plank will fit snugly against the wall even if the wall is not straight.

If the wall is straight, straightforward measure the width you need and cut the plank lengthwise with a table saw or circular saw. Make sure the cut edge is clean and straight — a rough edge will not sit flush against the wall and will be visible if the baseboard is removed later.

Installing the New Plank and Securing It

Before you set the new plank in place, explore a fresh bead of vinyl plank adhesive to the subfloor. Use the adhesive recommended by the plank manufacturer — different brands require different products, and using the wrong adhesive can cause the plank to fail. Spread the adhesive with a notched trowel in a thin, even layer across the entire area where the plank will sit.

Slide the new plank into place from the side, starting at one end and working it into position. Press down firmly along the entire length, paying special attention to the edges and the corners. Use a roller or a block of wood and a hammer to press the plank down evenly. Avoid walking on the plank for at least 24 hours while the adhesive sets. If you must cross the area, step only on the adjacent planks, not on the new one.

Dealing with Baseboards and Trim

If the baseboard or trim was removed to access the plank, reinstall it now that the new plank is in place. If the baseboard was left in place, check that the new plank sits flush underneath it. Sometimes the baseboard will need to be lifted slightly or shimmed to sit evenly over the new plank, especially if the old plank was damaged and sitting lower than it should have been.

If you had to cut the plank to fit the wall, the cut edge will be visible at the wall line. If the baseboard covers this edge, you do not need to worry about appearance. If the edge is exposed, you can paint it with a color that matches the plank, or you can install a thin trim piece to cover it. Most vinyl plank manufacturers sell matching trim pieces for this purpose.

Common Mistakes to Avoid

The most common mistake is leaving old adhesive on the subfloor. Even a thin layer of old adhesive will prevent the new plank from sitting flat, and the plank will feel soft or bouncy underfoot. Take the time to scrape and heat-gun the subfloor until it is completely clean.

Another mistake is cutting the plank too narrow or too wide. Measure twice and cut once. If you cut it too narrow, there will be a visible gap between the plank and the wall. If you cut it too wide, you will not be able to slide it into place, and you will have to remove it and cut again.

Do not rush the adhesive cure time. Vinyl plank adhesive needs at least 24 hours to set properly. Walking on the plank too soon can shift it out of position or create air pockets underneath, both of which will cause problems later.

Frequently Asked Questions

Can I replace just the damaged plank without cutting it in half?

No, not if it is against a wall. Vinyl planks are rigid and cannot be bent or flexed enough to slide out sideways past a wall. Cutting it into two pieces is the only way to remove it without moving the wall or baseboard.

What if the subfloor is uneven or has a dip where the old plank was?

Use a self-leveling floor compound to fill the dip before you lay the new plank. Pour the compound into the low spot, spread it with a trowel, and let it dry according to the product instructions — usually 24 to 48 hours. This will may support the new plank sits at the same height as the surrounding planks.

Do I need to remove the baseboard to replace the plank?

Not always. If the baseboard is nailed or screwed to the wall rather than the floor, you can work around it. If it is glued to the floor or if it is in the way, remove it carefully with a pry bar, replace the plank, and reinstall the baseboard afterward.

What type of adhesive should I use for vinyl planks?

Use the adhesive specified by the plank manufacturer. Most vinyl plank brands require a specific urethane or acrylic adhesive designed for their product. Using the wrong adhesive can void the warranty and cause the plank to fail. Check the manufacturer's instructions or the back of the plank packaging for the correct product name.

How long do I have to wait before I can walk on the new plank?

Wait at least 24 hours before walking on the plank. Some adhesives require longer cure times — check the product instructions. If you must cross the area before 24 hours, step only on the adjacent planks, not on the new one.
