FibaTape wall repair fabrics are fibreglass mesh materials that have an adhesive back and are manufactured by Saint-Gobain Technical Fabrics. They are applied to cracked, damaged areas of both sheetrock and plaster walls to stop them from spreading. After the fabric is covered and sanded down, the damaged wall is restored to its original appearance. FibaTape wall repair fabric is available in multiple widths, which reduces the amount of cutting required.
Dampen a clean cloth with 1 to 2 tbsp of water, and wipe the entire wall from top to bottom to remove any plaster chunks and dust from the surface. Allow the wall to dry for 10 to 15 minutes before proceeding.
Unroll the FibaTape and cut off the amount you need from the roll, using sharp scissors. Peel off the protective backing to reveal the sticky adhesive.
Position the FibaTape over the damaged section of the wall, and press it down smoothly until it sticks. Press from the top to the bottom of the fabric to ensure there are no wrinkles or bubbles.
Open a tub of joint compound if you have sheetrock, or plaster if the walls are plaster. Insert a putty knife into the material and smooth it over the FibaTape in a thin layer only until none of the fabric is visible.
Allow the plaster or joint compound to dry overnight until it is completely dry and hard to the touch.
Sand the entire area with fine-grit sandpaper until you can no longer feel a difference in the wall when you run your hand over it.
Wipe the wall down well with a damp rag to remove the sanding dust, and then paint the wall with your desired paint colour.
You can use the wider FibaTape fabrics to repair entire walls, such as plaster walls with multiple chunks missing.
