How to effectively use fibreglass mesh tapefibreglass mesh tape?

Fibreglass mesh tape is a popular material used for reinforcing drywall joints and repairing cracked walls. When used correctly, it can provide a strong and durable finish that will last for years. Here are the steps to effectively use fibreglass mesh tape:

Step 1: Prepare the surface.

To effectively use fibreglass mesh tape, start by preparing the surface you will be applying the tape to. This involves cleaning the area thoroughly to remove any dirt, dust or debris that may be present. Use a dry cloth to wipe off any loose dust and debris, and then use a damp cloth or sponge to clean the surface. Allow it to dry completely before moving on to the next step.

Step 2: Cut the tape to size.

Next, cut the fibreglass mesh tape to the desired length. Use a pair of scissors to cut the tape to the size you need, ensuring that it is slightly longer than the joint you will be covering. This will allow you to overlap the tape onto the adjacent wall, ensuring a strong and secure finish.

Step 3: Apply joint compound.

Before applying the tape, apply a thin layer of joint compound to the area where you will be placing the tape. This will help the tape adhere to the surface and create a smooth finish. Use a putty knife to apply the joint compound evenly to the area.

Step 4: Apply the tape.

Once the joint compound is applied, place the fibreglass mesh tape over the joint and press it firmly into place, ensuring that it is flush with the wall surface. Use a putty knife or drywall knife to smooth out any bumps or wrinkles in the tape, ensuring a smooth and even finish. Repeat this process for the entire length of the joint, overlapping the tape by about an inch or so on either end.

Step 5: Apply a second layer of joint compound.

After the tape is applied, allow it to dry for at least 24 hours. Once it is dry, apply a second layer of joint compound over the tape, ensuring that it overlaps onto the adjacent wall. Use a putty knife to smooth out any bumps or wrinkles in the compound, creating a smooth finish.

Step 6: Sand and prime.

Once the second layer of joint compound is dry, use sandpaper to sand down any bumps or high spots in the compound, creating a smooth finish. Vacuum up any dust or debris, and then apply a coat of primer to the area, allowing it to dry completely.

Final thoughts.

Fibreglass mesh tape can be an effective way to repair cracked walls and reinforce drywall joints. By following these steps, you can ensure that you are using the tape correctly and creating a strong and durable finish that will last for years.
