Pergo is a brand of laminate flooring that is designed to float over the subfloor, requiring no glue or nails for its installation. The individual 3-foot sections are engineered with interlocking tongue and groove edges so each section can be snapped to adjoining sections. If a board is badly damaged, you can remove it by removing part of the floor until you can access it. If this is impractical, you can cut it out with a circular saw. If you do this, however, the replacement board will have to be glued in place.
Repair small imperfections with a laminate flooring touch-up kit. The kit will have everything you need to fill small holes and blend them into the rest of the floor. Be sure the kit matches your floor colour and style.
Replace a damaged board that is close to a parallel wall by removing flooring until you get to the damaged board. Pry off the baseboard with a pry bar and unlock the sections by lifting them and pushing them towards the wall. Remove the damaged board and install a new one, then replace the rest of the boards and nail the baseboard back in place.
Cut out a board that is so far from the wall that removing the flooring is impractical. Start by drawing a rectangle around the edge of the damaged board with a straight edge and a pencil. This rectangle should be 1 1/2 inches from the sides and ends.
Drill 3/16-inch holes at the corners of the rectangle and the corners of the board. Drill two more relief holes in the middle of both long edges of the board, about 10 inches apart.
Set the depth of the blade of a circular saw to the thickness of the board, or about 3/8 inches, and cut out the centre rectangle. Stop cutting when you reach each pre-drilled hole. Lift out the centre section. Make diagonal cuts at each corner to the pre-drilled holes in the corner of the board, and straight cuts from the edge of the rectangular cut-out to the relief holes. Lift and unsnap all the sections carefully, starting with the sides.
Prepare the replacement board by sawing off the bottoms of the grooves on one side and one end. Then cut off the tongue on the other end with a sharp utility knife.
Test the board by snapping the tongue into the groove of the adjoining board to make sure that you have cut off everything that needs to be cut and that the board fits. Then remove it and spread contact cement carefully on the tongues of the adjoining boards and snap the replacement board back into place. Place a heavy weight on the board to hold it down while the glue dries.
When you are removing floorboards, be careful not to damage the interlocking mechanisms, or the boards may not snap back together easily.
Cutting laminate flooring produces a fine spray of wood and plastic that can damage you eyes, so always wear safety glasses while you do this. Use a straight edge when you cut the tongue off a board with a utility knife to prevent the knife from slipping and damaging the surface of the board or yourself.
