How to repair carpet

repair carpet

Accidentally, you can even damage the carpet, which is carefully cared for. You can burn through the carpet with cigarette ash. The sharp end of a fallen broken toy can cut through the carpet fibers to the base. And stains from certain liquids persistently resist shampoos and stain removers. However, if you have some carpet scraps and some inexpensive tools, you can safely and discreetly repair the carpet.

Hide the scraps if you are laying a carpet, or ask the seller for them if you are buying a house with carpets. If you don’t have any clippings, you can cut off some of the carpets in invisible places, such as under cabinets. Minor damage can be repaired by restoring the pile or loops of the carpet. 

If you do not have any carpet scraps, pull the threads around the perimeter of the carpet from its edges. New threads are sewn to the carpet with a rounded surgical needle with strong thread; you can make such a needle yourself by heating a regular sewing needle in a flame and bending it.

More extensive damage can be repaired by patching it. To avoid damage to the fibers of the front side of jacquard carpets, you need to unscrew and sew the patch from the wrong side. On pile carpets, patches are placed on the front side, using a piece of cloth and latex mastic. Surface tears in which the top layer of the carpet has come off the base are repaired from the front side by gluing;

if the base is visible around the hole, carpet threads are sewn in this place. Gaps that have also affected the carpet base are repaired on the lower side. Never stick the adhesive tape to the front surface of the carpet, even temporarily, as it is impossible to tear it off without damaging the carpet fibers.

Despite the fact that most repair methods are not difficult, they require patience. For example, when replacing carpet threads, do not rush; you will get better results if you sew one thread per stitch in the damaged area. Apply the glue carefully so that its excess does not get on the carpet surface. Before cutting out the patch, make sure that it matches the pattern and direction of the fibers in the damaged area. 

Always try to use the smallest piece of carpet first, so that if you make a mistake, there is always material to correct the mistake. And if you’re doing something that you’re doing for the first time, take the time to train on unnecessary clippings before you start working on the carpet itself.

Preparing for pile restoration

Use scissors with short curved ends (medical) to cut the pile from the damaged area to the base and remove the remnants of cut threads or loops with tweezers. To make it easier to remove fiber residues, wet the damaged area of the carpet with a cotton swab soaked in gasoline, which softens the adhesive compound that holds the threads in the base. To replace, pull out the fibers or a whole thread of looped yarn from the edge or trim of the carpet.

Sewing on the pile

Remove any remaining fibers from the cleaned area so that the base is visible. Thread the needle with a thread that matches the base thread in color and thickness. While holding the V-shaped carpet thread with tweezers, secure the thread in the base and make a loop over the V-shaped thread. Insert the needle into the base at the point where the thread is attached and gently pull the thread, pressing the carpet thread to the base. Without cutting the thread, sew a second V-shaped piece of carpet thread to the adjacent warp thread. 

Continue working until you have covered the entire surface of the base. Sew several times around the last piece of carpet thread to secure it. On carpets with a latex-coated base, push the new fibers apart and moisten the carpet with a cotton swab soaked in gasoline to glue the stitched threads to the base. Trim the uneven ends of the new threads with scissors.

Replacement of loop carpet threads

Press the loops around the lint-free area. Using a semicircular needle, sew a long piece of untangled yarn to the base, from which the carpet loops are made, then make another stitch to form a loop. Pull the loop so that it matches the shape of the existing carpet loops. 

To do this, you can use a match or other object that will standardize the size of the loops (inset). Continue making loops without cutting the threads until the entire damaged area is filled in. Secure the end of the yarn by making several repeated stitches in one place.

Putting a patch on a jacquard carpet

1. Loosening the carpet tension

Use a tensioning device to reduce the tension on the carpet in the corner of the room closest to the damaged area. Use an awl to lift the carpet off the grappling hooks. When the corner is clear, remove the carpet from the grippers along the two walls.

2. Cutting out the damaged area

Mark the corners of the damaged area on the front side of the carpet with pins that are inserted into the carpet and lining. Cut a stencil out of thick cardboard to match the shape of the marked area, then fold the carpet so that the underside is exposed. Position the stencil so that its edges are parallel to the warp threads. Use a linoleum knife to cut out the damaged area around the edges of the stencil, trying to cut only along the base.

3. Cutting out a patch

Place the cut-out area of the carpet on the front side of the unwanted carpet trim. Align the fiber directions and pattern, if the carpet is patterned, then insert pins into the carpet trim at the corners of the cut area. Remove the cut-out area, turn the carpet piece over, and use a stencil to cut out the patch as described in step 2.4.

4. Installing the patch

To prevent fraying, apply a thin layer of glue to the edges of the carpet base around the hole and the edge of the patch. The glue should not get on the carpet pile. Align the fiber direction and, if necessary, the patch pattern with the carpet pattern. Press the patch back into place, starting from one corner in the direction of the diagonally opposite corner. Use the blunt end of the needle to remove all the carpet fibers on the front side.

5. Sewing on the patch

Align the edges of the patch with the edges of the hole. Lift the two edges of the joint so that it is convenient to sew, and sew the two edges with thick thread alternately long (30 mm) and short (20 mm) stitches. Periodically inspect the surface of the carpet and remove any carpet fibers trapped in the seam. After sewing the patch, straighten the carpet and pull it over the grippers with a tension device. Put a load on the patch for several hours, so that the fibers straighten out and the patch becomes invisible.

Putting a patch on a voluminous pile carpet

1. Attach the damaged area to the floor

If the carpet is stretched with grippers, place strips of carpet scraps around the damaged area at a distance of about 200 mm from the edges of the damaged area and attach them with 25 mm furniture nails at intervals of 75 mm. This procedure reduces the tension of the carpet in the area of patching. If the carpet is attached with sticky tape or lies loosely on the floor, there is no need to attach it.

2. Cutting out the damaged area

Make a cardboard stencil that matches the size of the damaged area and place it on the carpet. With the blunt side of the linoleum knife blade, divide the carpet pile “in the middle” along the edges of the stencil, then push the pile apart with your fingers. Cut through the base of the carpet using the stencil, being careful not to cut the lining, then lift the cut area by one corner and remove it. Cut a patch from the carpet trim, using a cut-out area to align the pile direction and pattern, and a stencil to make it easier to work with a knife.

3. Installing fabric tape

The patch will be held in place by using fabric and mastic strips on the wrong side of the carpet. Cut four strips of fabric so that they are approximately 25 mm longer than the sides of the hole. Apply a thin layer of latex mastic to the tape and place the tape under the edges of the hole so that the joint lines are in the center of the tape. Apply a thin layer of glue to the edges of the hole, making sure that the glue does not get on the carpet pile.

4. Attaching a patch 

Combine the slope of the fibers and the pattern of the patch and carpet. Press the patch back into place, starting from one corner in the direction of the diagonally opposite corner, taking care not to stain the front side of the carpet with glue. Slide the edges of the hole patch together and press them with your palms. Use an awl to free the carpet fibers or loops that are caught in the joint, then use your fingers to smooth out the carpet fibers and patches so that they mix and the seam becomes invisible. Load the seam for several hours with a stack of books. If the carpet is stretched on the grippers, after approximately five hours, remove the temporarily nailed strips from the carpet scraps and restore the carpet tension with a tensioning tool.

Surface tear repair

1. Applying mastic

If the base is not damaged, lift the torn area of the carpet, remove the lint, and spread a thin film of mastic on the base.

2. Sealing the tear

While holding the edges of the tear with your hand, smooth the surface of the carpet with a smooth object, such as a lemonade bottle. While firmly pressing down on the carpet, move the bottle away from the tear in different directions to evenly distribute the mastic under the carpet between the fibers without squeezing it out on the surface. If the adhesive still appears on the surface, remove it immediately with water and carpet cleaning shampoo. Four to five hours after the glue dries, sew on the loose fibers.

Repair of gaps

Sewing up a jacquard carpet

Using a tensioning device and an awl, remove the carpet from the grippers in one corner, then wrap the carpet so that the gap is visible from the wrong side. Holding the edges of the gap at an angle so that it is convenient to sew, sew the two edges with thick thread alternately long (30 mm) and short (20 mm) stitches. Cut out a ribbon from the fabric that will cover the gap, and smear it with a thin layer of latex mastic. Allow the mastic to dry for a few minutes and press the tape firmly against the sewn tear spot on the wrong side of the carpet. Unfold the carpet and pull it over the grippers using the tension device.

Using sticky tape

Carpets with a foam base can be repaired as described above or with adhesive tape. Lift the carpet off the grippers or tear off the double-sided adhesive tape from the floor and wrap the carpet. Align the edges of the tear, then press a single-sided adhesive tape about 50 mm wide to cover both edges. Wait a few hours, then unfold the carpet and secure it to the grippers or, if the carpet has a foam base, stick it to the floor with double-sided adhesive tape.
