The installation of Pergo floors is easy because of the simple groove and tongue system incorporated in the design of the flooring pieces. However, before installation, a number of precautionary measures must be taken to ensure that the floor being installed will stand the test of time.
First and foremost, the Pergo flooring pieces must be left in open boxes so as to adjust to the levels of moisture in the air within the room. This process is referred to as acclimatization and it takes 48 hours. For extremely dry or humid areas, the period should be extended to at least 72 hours. The planks are thus able to swell and shrink appropriately before installation.
The condition of the subfloor also matters. Pergo can be installed over virtually any subfloor, be it concrete, wood, vinyl or even tile, but installation over carpet and padding is not advisable. The subfloor must also be flat, well bonded and dimensionally stable. If the existing subfloor is considerably ruined (i.e. with numerous indentations and discontinuities) remove it by use of the appropriate tools. Take care not to tamper with asbestos products as you will risk contacting cancer.
If the floor is uneven, you will have to go the extra mile of removing all the bumps or peaks on the subfloor. Similarly, fill all the depressions with floor leveling compound so as to ensure the stability of the floor that will be floating on top of the subfloor. The rule is that there should be no more than,1-10.” unevenness per 3 foot span. This flooring should not be installed in rooms with sump pumps, mobile homes, boats or planes.
A moisture test should also be performed on the subfloor to determine if high moisture exists in the subfloor. For the calcium chloride moisture test, the values must be less than 5lbs/1000ft2/24hr. For moisture meters, the values must be less than 4.5%. If these values are exceeded, the floor cannot be installed until the moisture content is reduced by other methods, otherwise the laminate flooring will not last long.
Thoroughly clean all the debris from the subfloor before the installation. Likewise, drilling, sawing, sanding and machining of the planks should be done in a separate room or outside so that the dust generated does not remain buried below the Pergo pieces. After all these preparations, it may be necessary to install the planks over a single underlayment appropriate for laminate floors. Some models, however, come with attached underlayment.
With the above recommendations, you are sure to enjoy your floor for a long time without any problems.
