a second plank (make sure it is snug against the wall) on top of the overlapping plank.  You should be working with the depth of three planks -- one on top of another.   Mark your measurements onto the overlapping plank (the one sandwiched in the middle).  You will cut the width of your last row to the measurements you have just made. Make sure you maintain the tongue and groove of your flooring and that you cut the CORRECT SIDE!!! Remember: Measure twice, Cut once! Maintenance: For daily maintenance, you can use a damp mop to clean the cork floors. Too much moisture can cause warping which is not covered under warranty. Quickly wipe spills from the floor to protect cork from excess liquid. Use door mat to prevent sand and dirt or other abrasives. 4. It's wise to use felt pads under the legs of furniture to avoid scratching and permanent denting. When moving heavy objects try to lift instead of pull. If this is not possible, then using pieces of heavy cardboard under the furniture, while moving it, will help keep your floor from being scratched. SEALING: Our cork products have been surface-sealed with three layers of water based polyurethane. To facilitate installation, the seams are not sealed from the factory. After installation we recommend you re-coat the entire floor. This will seal the seams to protect the joints against dirt accumulation and water spillage. Apply 2 coats of floor grade water based polyurethane for light residential use
