Acclimation of Laminate Flooring

The manufacturers of most laminate floors require the cartons of flooring to be acclimated for 48 to 72 hours prior to installation.  Acclimation requires conditioning of the flooring material at or near occupancy level. Check the installation instructions to see how they want the material stacked for installation and if the cartons are to be opened or left unopened.

The flooring material needs to be acclimated in the area of installation. This means that if the laminate is to be installed in the family room it should be acclimated in that room.

Storing the laminate flooring in the garage is not acclimation even if the garage is attached. Storage of the material at the store or warehouse of the dealer or installer is not acclimation unless the floor is to be installed in the store or warehouse.

Not all laminate manufacturers require acclimation. If the dealer or installer says it is not necessary to acclimate insist that they show you where the manufacturer states that in writing. Don’t make the manufacturers, dealers or installers problem yours. If they say that the floor does not require acclimation insist on getting this in writing.

When a floor acclimates the product is adjusting to the humidity of the area of installation.

All wet work in the area of installation such as plastering and painting must be completed prior to the start of acclimation.  All windows and doors must be installed prior to the start of acclimation. The heating and air conditioning system must be operational at or near occupancy levels. If installing over concrete the concrete should have been tested and found to be at acceptable levels for the installation of the laminate.

When a floor is not acclimated prior to installation it can be hard to click together chipping or damaging the edges of the laminate. A floor that is not acclimated to its environment is more likely to experience problems such as expansion, tenting, squeaking and buckling after installation.

If you are unsure of the laminate manufacturers installation requirements a copy of them is often contained in each carton. Most manufacturers’ installation instructions are also available on LaminateFloorProblems.com

Laminate Floor Problems and Concerns

Laminate Floor Problems

Delamination

When the laminate releases from the core material this results in delamination.

Delamination may be seen in the field of the blank as a bubble.
Delamination may also be found along an edge.

When an area of delamination continues across the seam of the planks this is almost always a site related condition.

Core Voids in surface of Laminate Floor

• Core voids are indentations in the face of the laminate floor.
• The best way to tell a manufacturing core void from a dent caused by a dropped object is the absence of stress cracks. A dropped object usually leaves cracks while a core void does not.

Bumps or Blisters in Laminate Face

Blisters are small bumps in the finish of the laminate floor. These bumps often look like a pimple and can be very difficult to see during installation.

Chatter Marks

Chatter marks appear as wavy bands or lines across the width of the plank.

Chatter mark bands can be very difficult to see during installation and are most visible with reflective light.

Proud Edges

Proud edges are seen as a difference in height at the joints of the laminate plank.

Proud edges can be found on the side or end.
Most laminate flooring manufacturers consider proud edges up to 0.1mm  acceptable and within manufacturing tolerance.

Some manufacturers have different or expanded tolerances. As an example Pergo considers proud edges up to 0.2mm acceptable if they do not affect the appearance or function of the floor. Pergo also considers 5 or less proud edges per 300 sq. ft. acceptable.

Micro Chipping

Micro chipping is seen as continuous small chips along the edge of the plank.

The chips usually appear white in color.

These chips occur during milling of the laminate plank as the result of a dull milling tool.

Color Deviations

Some manufacturers state that there will not be a color difference between runs. When this is stated a color difference between runs is the laminate manufactures floor problem.

A color difference would be a difference in hue, shade or gloss.

At times what appears as a color difference is actually the installation of two different colors of laminate floor. If the carton labels or plank markings show this to be the same style and color this is a manufacture related condition.

If the packaging shows that these were different styles or colors the manufacturer will unlikely warrant the difference and this laminate flooring problem will be between the consumer and supplier or retailer.

Fading

• Fading warranties differ with each manufacturer.

• Some laminate flooring manufacturers guarantee their floor not to fade due to sun or electrical lighting.

Gaps and Glue Voids (Glued Floors)

• A feeler gauge is used to indicate a gap in the glue and to measure the size of the gap.
• Voids or gaps in the glue will allow moisture to penetrate at the seam resulting in swelling along the plank edges.
