Installing plastic below vinyl floors is a manageable DIY project. Before installing vinyl plank flooring, you must determine the best type of vinyl plank for your renovation needs. Vinyl planks can be sorted into three main categories based on their installation method: GripStrip, click-lock, and glue down. The underlayer is a 1/4-inch-thick layer of plywood that smooths out the floor and provides a sturdy base for the vinyl. It is important to prepare the subfloor so that it is clean, dry, and level. You can use a self-leveller on low spots and/or sand high spots of wood or concrete. The key to success is preparation, accurate measurements, and proper tools.

What You'll Learn

Prep the subfloor
Preparing the subfloor is an important step in ensuring a successful vinyl flooring installation. Here are the steps you should take:
First, remove any existing flooring that may be present. If you have carpet, pull it up, and take out any threshold strips that trim the doorways. If there are nails or staples, ensure they are driven below the floor surface. If you encounter any nails or staples that are not flush with the surface, you can either pull them out or hammer them in. A metal trowel can be used to locate any nails or staples by dragging it across the floor and listening for a telltale 'tink' sound.
Old flooring and adhesives may contain asbestos, so it is important to consult your local county or a private testing laboratory before disturbing or removing them. Once the old flooring is removed, fill any holes or cracks.
Next, you will need to address any unevenness in the subfloor. If you have a hardwood, embossed, cushioned, buckled, or uneven floor, it is recommended to install an underlayment. Underlayment is a 1/4-inch thick layer of plywood that smooths out the floor and provides a sturdy base for the vinyl. It is important to stagger the seams of the plywood panels, leaving a 1/32-inch gap between them for expansion. If necessary, use a floor leveller or cement patching compound to smooth out any uneven areas where the underlayment panels meet. Allow it to dry, and then sand it smooth.
Before installing the vinyl, ensure the subfloor is clean, dry, and level within 3/16-inch change per 10 feet. You can use a self-leveller to address any low spots and sand down any high spots on wood or concrete surfaces. Keep in mind that some walls may not be straight, so it is important to create a square starting line. Mark the centre of each wall and snap lines between them with a chalk line. Measure from the centre to the starting wall, subtracting the expansion gap, and mark this distance at each end of the wall. Snap a chalk line between these marks to create a straight line against the wall.

Choose the right underlayment
When installing vinyl flooring, the type of underlayment you choose will depend on several factors, including your budget, the type of subfloor, and whether the space has moisture issues or requires sound or thermal insulation.
Firstly, you should always clean the subfloor thoroughly before installing underlayment. Ensure every bit of dust, dirt, and debris is removed, and the surface is washed and completely dry.
If your vinyl flooring has a built-in underlayment, you can add compressed cork to enhance sound insulation. However, cork is not a moisture barrier and can retain moisture, leading to mould formation if not installed properly. Therefore, if installing over a concrete slab, always lay a moisture barrier first.
Foam is a cost-effective option that pairs well with plywood subfloors, but it lacks a vapour barrier, so it is not suitable for moisture-prone areas. Felt offers superior sound control compared to foam and is an excellent eco-friendly option, as it is made from recycled fibres. Particleboard is another budget-friendly choice, but it is not durable and cannot handle moisture exposure.
Rubber is considered the best underlayment for vinyl flooring, offering excellent protection against moisture and superior sound and thermal insulation.
If you are unsure about which underlayment to choose, it is always best to consult a flooring expert.

Measure and cut the vinyl
Measuring and cutting vinyl flooring is a crucial step in the installation process. Here is a detailed guide to help you through the process:
Preparation
Before you begin measuring and cutting the vinyl, it is essential to prepare the room by removing any furniture, appliances, or fixtures that may obstruct your work area. Take measurements of the room's length and width to determine the square footage or square yardage. With these measurements, you can estimate the amount of vinyl flooring required, adding an extra 10% to 20% for cutting mistakes and future replacements.
Measuring and Cutting Techniques
There are two primary methods for measuring and cutting vinyl:
Method 1: Direct Measurement and Cutting
This method is suitable for rooms with fewer angles or obstacles. First, measure the entire floor area. Then, cut the vinyl 3 inches wider than the floor area on all sides. Lay the vinyl in place and trim the excess for a precise fit.
Method 2: Template Transfer
For rooms with intricate shapes, angles, or recesses, creating a template ensures a more accurate fit. Cut heavy construction paper into strips and tape them together to form a full-sized copy of the floor. You can also use graph paper to sketch your floor plan to scale. Transfer the template to the vinyl, marking the cutting lines. Cut the vinyl accordingly, and you may need to use a utility knife or a jigsaw for this step.
Cutting Tips
- Always double-check your measurements before cutting.
- When cutting, use a framing square to guide your cuts and ensure straight edges.
- For small pieces, use the scoring and snapping technique. Score the vinyl with a utility knife, then snap it off.
- For lengthwise cuts, a jigsaw is recommended.
- Wear protective eyewear when using power tools, and handle them with care.
Remember, accurate measurements and careful cutting are essential for achieving a seamless and professional-looking vinyl floor installation.

Install the vinyl
Installing vinyl plank flooring is a fairly simple process, even for beginners. There are three main categories of vinyl plank based on their installation method: GripStrip, click-lock, and glue down.
GripStrip
GripStrip vinyl plank flooring has a manufacturer-applied adhesive layer that connects the planks to one another. This installation method creates a floating floor, meaning the vinyl planking covers the subfloor without adhering or fastening to it. This is a mess-free way to install new flooring without having to remove the existing floor.
Click-Lock
Interlocking vinyl plank flooring, also known as click-lock, creates a floating floor through the use of tongue-and-groove joints that easily snap together. For the first row of vinyl planks, you only need to click in the width of the plank. Insert at a slight angle and rotate downward. Then, use a rubber mallet to tap the plank into place. For the rest of the room, the planks have to click in both lengthwise and widthwise.
Glue-Down
Glue-down vinyl plank flooring adheres to the subfloor using either hard-set or pressure-sensitive adhesives. Hard-set adhesive is spread along the subfloor, and then the vinyl planks are laid down on top. Pressure-sensitive adhesive is already on the bottom of the plank and bonds to the subfloor when the plank is pressed into place.
General Installation Tips
- Measure the area of the room in square yards and order a small amount of extra vinyl above your measurements.
- Remove any furniture, appliances, or old flooring that will be in the way.
- Allow the new vinyl floor to acclimate to the room by leaving it in the room where it'll be installed for at least 24 hours before cutting.
- There are two ways to measure and fit vinyl: either measure the entire floor area and cut the vinyl 3 inches wider than the floor area on all sides, or make a template of the floor layout and transfer it to the vinyl.

Finishing touches
Once you have installed your vinyl plank flooring, there are a few final steps to ensure a clean finish. Firstly, if you have had to cut any planks to fit, use any excess cut pieces to start new rows, ensuring that these pieces are at least 6 inches long. The joints of your vinyl flooring must be staggered at least 6 inches apart. You can measure and cut your first piece accordingly, using a cut end from the first row if necessary.
After laying your vinyl flooring, you may need to cut into your door framing if you are raising the floors higher than they were previously. Use a plank to mark a line on the framing and cut into it with a multi-tool. If you want to keep the pattern going, make a note of where the seams are in the previous rows.
Finally, for a clean look, purchase coordinating transition strips to use at doorways or when switching flooring types.
