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.
