Typically, where there is a seam, the traffic will need to be away from this area over night. These seams usually have a shiny coating on them that will dull down through the seasons. Although seams are not invisible, they should not stand out when looking at them from all for sides. You will almost always see the seam sealer coating. While still maintaining climate control throughout the life of the sheet vinyl AKA linoleum be sure to use the proper care and maintenance supplied from the manufacturer. We do stock most recommended cleaners here at Rice’s More Than Floors. As reminder most of these sheet vinyls are top-down waterproof. Do not flood these floors. The initial couple cleanings may be more intense after the install due to the dust that is disturbed in your space from the removal of your old floors, the dust that was on your substrate and some generated from our team. Although we do our best to control dust expect dust in your space and surrounding spaces. Utilize floor protectors on all items touching the surface of the sheet vinyl Do not allow wheeled traffic or wheels on your new sheet vinyl as this will accelerate deterioration of your floor and most manufactures do not warranty the sheet vinyl from wheels.
