Vinyl floors are a popular choice for many rooms in the home, including the basement, kitchen and bathroom. Sometimes their seams get loose or curl as part of the aging and consistent use, and it's not always hard to get those fixed.
Depending on the extent of seam damage, you will either use seam glue or a transition strip to fix the vinyl flooring. Seam glue is needed when the edges are simply out of place and loose. Alternatively when the edges are jagged and can't meet, that's when you need transitional strips.
To use seam glue, heat the seams with a blow dryer or steam iron placed on a towel so you can pull them back to expose the subfloor. Clean any dirt from the area, make sure the subfloor is dry, then apply a thin layer of vinyl mastic to the floor and press the seams back down. Place wax paper over it in case the mastic is forced out of the seams and then weight the area down overnight.
For transitional strips, measure the length of the seam and cut the strip using metal snips. Then fit the strip in place to make sure it covers the entire area. Using screws or nail, anchor the strip in place to make sure it doesn't move.
