Because vinyl sheet flooring is manufactured in 12-foot wide rolls, installation in rooms that are wider than 12 feet require the vinyl to be seamed. When you're installing vinyl sheet flooring in a room wider than 12 feet, there are important considerations to incorporate in the planning stages as well as certain procedures to ensure a proper seam in the vinyl. When seamed properly, the vinyl floor seam will blend well and any pattern will be maintained, as will the warranty and wear of the vinyl itself.
Install the first section of vinyl, taking care to spread the adhesive completely on the outside edges.
Roll out the second piece of vinyl, matching any pattern with the pattern of the first piece to ensure the integrity of the pattern.
Trim any areas as needed, such as doorways and walls on the second piece of vinyl before rerolling the sheet prior to actual installation.
Apply the adhesive to the floor and install the second piece, again taking care to match the pattern exactly with the first piece.
Roll the floor with an approved floor roller, as per manufacturer's installation instructions. Take care to roll the seamed area so that the adhesive will be spread uniformly beneath the edges where the two pieces meet. Allow the floor adhesive to dry completely as per manufacturer's directions.
Clean the vinyl flooring seam, using seam cleaner and a cloth applicator from the Seam Sealer Kit. Work in 8-inch lengths, rubbing the seam vigorously in a back-and-forth motion to remove any dust or adhesive from the seam edges and adding more seam cleaner when the cloth dries out.
Allow the seam cleaner to dry ten minutes. There will be a white residue where the excess cleaner has dried; buff the residue off with a clean, dry cloth.
Cut a 1/32-inch opening in the tip of the seam sealer applicator bottle.
Apply a uniform 1/8-inch bead of seam sealer to the seam, taking care to work in a straight continuous line along the seam. Allow to dry completely before using floor; typically this will be 2 to 3 hours.
Practice applying a uniform bead of sealant on a piece of scrap cardboard before applying the sealer to the actual seam.
Always follow the manufacturer's instructions when seaming vinyl sheet flooring. Seam sealer kits come with a drying accelerant; do not add the accelerant unless you are experienced with working quickly with seam sealing products.
