When the seams of vinyl sheet flooring separate and pucker, you can glue them back down with a vinyl flooring sealer kit. Generic types are available at home improvement stores; better, order kits made specifically for your type of flooring (if you know the brand) from a flooring dealer.
1) Use a hair dryer to warm the edges of the raised seam so you can peel them back to work on them.
2) Brush and/or vacuum the dirt out from the subfloor beneath the seam area.
3) With masking tape, protect the flooring surfaces on both sides of the seam.
4) Use a brush to apply multi-purpose sheet flooring adhesive to the back of the raised flooring.
5) Press the edges down and wipe off any excess adhesive. Then put a heavy, flat board along the seam and add weight with phone books or other heavy objects. Allow to dry overnight.
6) Use the seam-sealing kit as prescribed on the label to clean and permanently fuse the seam along the surface.
