Before you begin, it’s important to gather all the necessary tools and materials. Here’s what you’ll need:


  • Measuring tape
  • Miter saw or hand saw
  • Drill or screwdriver
  • Hammer
  • Pencil or marker
  • Safety glasses and gloves


  • T-moulding strip
  • T-moulding track
  • Adhesive or screws
  • Sealant
  • Sandpaper

When purchasing your materials, make sure to measure the area where you’ll be installing the T-moulding to ensure you purchase the correct length. You can find T-moulding strips and tracks at your local home improvement store or online.

Now that you have your tools and materials, let’s move on to the pre-installation preparation.

Pre-Installation Preparation

Before installing T-moulding, you’ll want to prepare the area where it will be attached. Here are the steps to follow:

Measuring the area

Using your measuring tape, measure the length of the gap between the two types of flooring. Be sure to add an extra inch or two to account for any irregularities.

Cleaning the surface

Clean the surface where the T-moulding will be attached. You can use a damp cloth or a mild cleaner to remove any dirt or debris.

Trimming the T-moulding

Using your miter saw or hand saw, trim the T-moulding strip to the correct length. Be sure to use your pencil or marker to mark the cutting line to ensure accuracy. Sand the edges of the T-moulding strip to smooth any rough edges.

With the pre-installation preparation complete, you’re now ready to move on to the installation steps.

Installation Steps

Now that you’ve prepared the area, it’s time to install the T-moulding. Follow these installation steps:

Attaching the T-moulding track

First, attach the T-moulding track to the subfloor. The track serves as a guide for the T-moulding strip and keeps it in place. To attach the track, use your drill or screwdriver to secure it to the subfloor. Be sure to use the appropriate screws or adhesive to ensure a secure hold.

Inserting the T-moulding strip

Insert the T-moulding strip into the track. Push the strip down into the track until it clicks into place. Use a hammer or mallet to gently tap the strip into place if needed. Be sure to check that the strip is level and flush with the surrounding flooring.

Securing the T-moulding with adhesive or screws

Finally, secure the T-moulding strip to the subfloor using either adhesive or screws. If using adhesive, apply a small amount to the bottom of the T-moulding strip and press it firmly into place. If using screws, drill pilot holes through the T-moulding strip and into the subfloor before securing it with screws. Be sure to fill any screw holes with wood filler and sand it down to create a smooth finish.

Finishing Touches

After securing the T-moulding strip, it’s time to add the finishing touches:

Trimming any excess T-moulding

If the T-moulding strip is longer than the gap, trim any excess with your saw. Use sandpaper to smooth the edges of the T-moulding strip.

Applying sealant

To ensure durability and prevent moisture damage, apply a sealant to the T-moulding strip. You can use a clear silicone sealant or a color-matching sealant to blend in with the surrounding flooring.

With these finishing touches complete, your T-moulding installation is finished! Not only does it provide a functional transition between two types of flooring, but it also adds a polished finish to any room. Remember to follow these steps carefully to ensure a successful installation that will last for years to come.

Finishing Touches

Once you’ve installed the T-moulding, there are a few finishing touches you can make to ensure it looks great and lasts for years to come.

Trimming any excess T-moulding

Using your miter saw or hand saw, carefully trim any excess T-moulding from the edges. Be sure to make clean cuts to avoid any jagged edges. Sand the trimmed edges to smooth any roughness.

Applying sealant to ensure durability

To ensure the T-moulding lasts as long as possible, apply a sealant to the edges. This will help protect the T-moulding from moisture and wear and tear. You can use a clear silicone or caulk to seal the edges. Simply apply a small bead along the edge and smooth it out with your finger or a caulk smoothing tool.

With these finishing touches complete, your T-moulding installation is now finished.
