How to Install LVP Flooring: Step-by-Step Guide for Click-Lock Vinyl Plank

This guide covers rigid-core click-lock LVP (SPC or WPC), which is what most people buy for a DIY floor. It floats, meaning it is not glued or nailed down. The steps are simple. The results come down to prep and layout, which is where most DIY floors go wrong. Always read the installation instructions in your box, because gap sizes, stagger rules and underlayment requirements vary by product.

What you'll need

Tools

• Tape measure, speed square or framing square, pencil
• Utility knife with fresh blades (for score-and-snap cuts)
• Rubber mallet (white or non-marking), tapping block and pull bar
• Spacers, 1/4 to 3/8 inch, or scrap pieces cut to that thickness
• Jamb saw or oscillating multi-tool for undercutting door casings
• Jigsaw for notches and curves, hole saw for pipes
• Miter saw or table saw (helpful for rip cuts and cleaner cross cuts)
• 6 to 10 foot straightedge, chalk line
• Pry bar and nail puller for baseboard
• Moisture test kit or meter if you are over concrete
• Knee pads, safety glasses, hearing protection, dust mask

Materials

• LVP planks: room square footage plus 5 to 10 percent for waste (10 percent or more for lots of small rooms or diagonal layouts)
• Underlayment only if your product calls for it. Many planks have a pad attached. Do not add a second foam pad under those. See underlayment for LVP and laminate.
• 6-mil poly vapor barrier over concrete if the manufacturer requires it
• Floor patch or leveling compound for low spots
• Transition strips (T-molding, reducer, end cap) and stair nosing if needed
• Quarter round or baseboard, finish nails, caulk

Step 1: Prepare the room and the subfloor

1. Remove the old floor, or confirm it can stay. Carpet and pad always come out. Tile, sheet vinyl and hardwood can sometimes stay if they are flat, hard and firmly attached. Check can LVP go over an existing floor before you decide. In homes built before 1978, old vinyl, its adhesive and painted trim can contain asbestos or lead. Test before you scrape or sand, or have a certified pro remove it.
2. Remove baseboard. Score the caulk line, pry gently against a scrap block to protect the wall, and number each piece on the back so it goes back in the same spot. You can leave baseboard on and use quarter round instead, but pulling it gives a cleaner look.
3. Check flatness. Lay a long straightedge in several directions and look for gaps. Most LVP wants the floor flat within about 3/16 inch over 10 feet, and some products ask for 1/8 inch over 6 feet. Mark high and low spots with a pencil.
4. Fix what you found. Screw down loose subfloor and squeaks. Sand high plywood seams. Fill low spots with patch and feather the edges. Larger problems are covered in how to level a subfloor.
5. Test concrete for moisture. Over a slab, use a calcium chloride test or in-situ relative humidity probes (ASTM F2170). Compare the result to your product's limit. Basements need extra care, so read LVP in basements.
6. Undercut door casings and jambs. Set a scrap plank (and underlayment if used) against the casing as a height guide and cut the casing with a jamb saw or multi-tool. The new floor slides under it so you do not have to scribe around trim.
7. Vacuum. Any grit left behind becomes a bump or a click under the floor.

Step 2: Plan your layout

1. Pick a direction. Planks usually look best running the long way of the room or toward the main light source, like a big window or slider. In connected rooms, keep one direction throughout so you do not need extra transitions. More in which direction to lay flooring.
2. Calculate the first and last row. Measure the room width across the planks, subtract the expansion gaps on both sides, and divide by the plank's exposed width. If the last row comes out narrower than about a third to half of a plank, rip the first row narrower so the first and last rows are close to equal. Nobody wants a 1-inch sliver along the wall.
3. Check the end walls too. Do the same math along the length so you do not end a row with a tiny piece at a doorway.
4. Mix boxes. Open three or four boxes at a time and pull from all of them so the color and pattern variation spreads evenly.
5. Plan the stagger. End joints in neighboring rows should be offset at least 6 to 8 inches, or whatever your product specifies. Avoid stair-step patterns and H-joints, where joints two rows apart line up.

Step 3: Install the first rows

1. Cut off the tongue on the first row. Most click LVP starts with the groove side facing out into the room, so the tongue side against the wall gets trimmed off. Check your instructions, since a few products start the other way.
2. Set spacers. Place 1/4 to 3/8 inch spacers along the starting wall and the end wall. Walls are rarely straight, so if the first row has to be scribed to follow a wavy wall, do it now.
3. Lay the first row. Connect the short ends of each plank by angling and pressing down, or by tapping with a tapping block, depending on the lock. Cut the last piece of the row to length, leaving the end gap.
4. Start row two with the offcut. The cut-off piece from the end of row one often starts row two, as long as it meets the minimum length in your instructions. This keeps waste down and the stagger random.
5. Lock the long side. Angle the new plank about 20 to 30 degrees into the groove of the previous row, press forward, and lay it flat. Then tap the short end joint closed with the tapping block. The joint should be tight with no gap you can catch a fingernail on.
6. Check the first three rows for straight. Snap a chalk line or sight down the row. If the start is crooked, the whole floor will be crooked. Fix it now.

Step 4: Work across the room

1. Keep the rhythm. Angle, press, drop, tap. Walk on finished rows, not on the edge you are about to click into.
2. Score and snap cross cuts. For SPC, score the face firmly with a utility knife along a square, snap it over your knee or the edge of a plank, then cut the backing. WPC and thick products may need a saw.
3. Cut around obstacles. For a heat register or floor vent, mark and cut the opening with a jigsaw. For pipes, drill a hole about 1/2 inch larger than the pipe with a hole saw, cut the plank through the center of the hole, and glue the small piece back in behind the pipe. Cover with a pipe collar.
4. Fit under casings. Slide the plank under the undercut casing. When you cannot angle a plank into place, many products allow you to slide it flat and use the pull bar to close the joint.
5. Mind the toilet flange and cabinets. Floating floors go around fixed cabinets and islands, not under them. Keep the expansion gap there too.

Step 5: Install the last row

1. Lay a full plank directly on top of the second-to-last row, line it up, and set a scrap piece against the wall on top of it.
2. Trace along the scrap to mark the cut line. That transfers the wall's shape and the gap in one step. Measure at both ends of each plank because walls wander.
3. Rip the plank with a table saw or circular saw, click it in at an angle, and pull the joint tight with the pull bar.

Step 6: Expansion gap, transitions and trim

1. Pull the spacers. Leave the gap open. It gets covered by trim, not filled with caulk or nails.
2. Install transitions. Use a T-molding between floors of the same height, a reducer down to a thinner floor, and an end cap at sliders or the bottom of a step. Most products also need a T-molding break in very long runs or between rooms through narrow doorways, so check the maximum run length in your instructions. Placement is covered in flooring transitions between rooms.
3. Reinstall baseboard or add quarter round. Nail into the wall, not down into the floor. Trim should sit just above the plank surface so the floor can move under it.
4. Caulk where needed. Caulk the top of the trim to the wall. In bathrooms, many manufacturers call for a flexible silicone at the tub and around the perimeter. Follow your product's wet-area instructions.
5. Set appliances back on plywood or hardboard and put felt pads on furniture.

Common mistakes to avoid

• Skipping the flatness check. Click joints flex over dips and eventually break or peak.
• No expansion gap. Planks butted tight to walls or pipes can buckle when the house warms up.
• Pinning the floor. Nailing trim through the plank, or setting cabinets and islands on top, stops the floor from floating.
• Short end pieces and poor stagger. Pieces under the minimum length make weak joints. Repeating patterns look fake.
• Doubling up padding. Extra foam under an attached pad makes the floor bounce and strains the locks.
• Hammering the edge directly. Always use a tapping block. A mallet on the tongue will crush it.
• Ignoring moisture on concrete. Waterproof planks do not stop mold under the floor.

How long does it take to install LVP yourself?

A first-time DIYer can usually lay a bedroom in a weekend, including baseboard removal and reinstall. Pros are faster mainly because they have done the layout math and the tricky cuts many times. See how long LVP installation takes for timelines by room.

When to hire a pro

• The subfloor is out of flat by more than patching can fix, or the floor bounces or sags
• Concrete moisture readings are near or over your product's limit
• Stairs, which take precise cutting and solid nosing attachment
• Old flooring that may contain asbestos, or a pre-1978 home with painted trim you plan to cut or sand
• Kitchens where appliances, water lines and gas lines have to be moved
• Large open areas where layout errors are expensive and very visible
