1. Can Pergo be installed over my existing flooring material?
Pergo can be laid directly over most existing floors including ceramic tile, vinyl, and wood. Always remove carpeting and pad and remove parquet and strip wood flooring if it is installed on a concrete subfloor.

2. Can I install Pergo under cabinets?
We recommend that cabinets be installed before installing Pergo. Run the Pergo up to the kick plate, leaving an expansion space and cover the space with a Pergo quarter round or end molding. However, cabinets may be installed after the floor is in place IF they are NOT fixed or attached to the Pergo floor. Cabinets and islands can be anchored to the subfloor. Should any anchoring bolts or screws be placed through Pergo, the drilled holes must be larger than the diameter of the bolts to allow for the required floating floor expansion space.

3. Do I have to keep staggering the planks in my installation?
The first row should be started with a full plank, the second row with a 2/3 plank and the third row with a 1/3 plank. The distance between joints from one row to the next for the remainder of the installation must be 8" or greater.

4. What type of saw do you recommend?
A 10-inch table saw and sliding compound miter saw and a blade with 60-80 triple chip grind carbide teeth will provide the best cuts and longest use. Offset teeth on the saw blade (those that alternate left and right) will dull more quickly and make rougher cuts. For making circular cuts, such as those for pipes, use a Saber saw (jigsaw) with medium to fine-toothed blades.

5. In what lengths are the Pergo moldings available?
The Pergo End Molding, Stair Nosing, Hard Surface Reducer, Carpet Transition, T-Molding and the Four-In-One Molding are available in 78.75" length pieces. The Pergo Wallbase and Quarter Round are available in 94.5" length pieces.

6. Do I need a T-molding in my doorway?
A T-molding must be used in doorways and archways four feet wide or less. The only exception is for closets that are 30" deep or less, where the flooring may run continuously.

7. How do I install a Pergo End Molding?
Pergo End Molding is used to join Pergo to another floor which is higher and to finish the floor at vertical surfaces such as exterior door thresholds, sliding glass doors, raised hearths, marble sills and tub and shower basins.

Step 1. Stop the finished Pergo flooring 1/2" from any vertical surface where you will install the end molding to accommodate for the molding's vertical leg.

Step 2: Cut the end molding to an appropriate length and apply Pergo Sealant or a 100% mildew-resistant silicone sealant on the edge of the end molding where it comes into contact with the vertical surface. Set the molding into the opening and press it firmly against the vertical surface.

Step 3: Clean up the excess sealant with acetone, mineral spirits or denatured alcohol.

8. What if the parts of the Four-In-One Molding feel loose after I snap them together?
The components will tighten when installed in the track.

9. What is the proper method for separating previously assembled components of the Four-In-One Molding?
If you must separate an assembled molding, slide the components apart instead of pulling them apart.

10. Is it normal for the joints of a recently installed Pergo Floor to appear swollen?
On Pergo glued floors, you may notice swelling along the joints of your floor during the first 6 to 8 weeks after installation. THIS IS NORMAL. In fact, it is a good sign that an adequate amount of Pergo Glue has been used. It is caused by the absorption of glue in the core material and will disappear as the glue fully cures.
