How can I mend flooring seam?

It's very difficult to "fix" this -- you need to get the underside of the flooring completely clean of any grit sticking to any adhesive beneath it and then heat the flooring while weighting it to get the vinyl to lay flat again -- but not so much heat that it melts it -- such as heating it with a space heater or with a hair dryer -- and even that may not force it back into it's original flat shape.

If there is a seam in the plywood or other subfloor directly beneath it, that may be moving as you walk on it and caused the problem; if so, the problem would recur unless you stabilize the subfloor so it doesn't rise/fall w/weight.

One alternative to repair is to cut out the area and replace it -- can work if you have matching floor covering on hand. another alternative is to not try to match it -- use the problem as an opportunity to accent pieces to the flooring ... if the pieces you add would be where they make sense visually.

Another alternative is to cut out a narrow strip of the floor covering where it is damaged actually damaged, paint the subfloor to "match" color of what the color of the floor covering should be and then add multiple thin layers of polyurethane atop it to make it floor level -- "building" floor covering with the polyurethane.

A better option, if within budget, is to consider whether or not you want to replace the floor covering in that room.

Not at all difficult. I have done this many times. You can do it, provided you use the right type of glue and a special seam sealer kit, available at most flooring stores. First, heat the vinyl edges of the seam with a hair dryer. This should make the edges easier to peel back, so you can sweep away any dirt or debris. Line the seam with masking tape to protect the surface. Apply a multipurpose sheet flooring adhesive to the backing. Then flatten the seam with a weighted board while the glue dires. Use the seam sealer kit to bond together the edges of the seam. The kits typically contain a cleaner, applicator, sealer and catalyst—just follow the directions on the package. ***** https://www.google.com/#q=vinyl+flooring+adhesive&tbm=shop ***** https://www.google.com/#q=mend+vinyl+flooring+seam&tbm=shop

Here is a really helpful discussion from a Hometalker with a similar problem to give you some more direction: http://www.hometalk.com/diy/floors-ceilings/q-laminate-flooring-is-curling-up-at-the-seams-can-it-be-repaired-easily-9821279 Good luck!!!
