The 4mm wear layer is able to be sanded and refinished several times over its lifespan.
Wear layer on engineered wood flooring.
An engineered floor with a 4mm wear layer or thicker can be sanded and refinished approximately 3 to 5 times over the lifetime of the floor.
What most people fail to realize is that a quality piece of engineered hardwood can be refinished as many times as solid hardwood.
A very popular thickness for a high quality engineered hardwood floor is 4mm.
A thicker wear layer contributes to a floor lasting longer as it can be sanded.
What this means is that somewhere around 5mm of it s surface can be removed in its lifetime through sanding without risking exposing the tongue and groove structure or causing the floor to significantly weaken.
These two elements combined present you with an engineered wooden floor.
Approximate lifespan 40 50 years.
The wear layer can vary in thickness from as thin as 2mm up to 6mm.
By using the ideal 3 16 wear layer you now have the same wear layer as a solid wood floor.
An engineered floor with a 3mm wear layer can be sanded and refinished approximately 2 to 3 times over the lifetime of the floor.
The 4mm wear layer is a thickness used with high quality engineered hardwood flooring.
Wear layer is that surface on the wood that can be re sanded and refinished until it reaches the tongue and groove.
Approximate lifespan 50 100 years or more.
To answer this question simply the wear layer is basically the thickness of hardwood that sits on top of the multiply core of engineered wood flooring.
Now your floor will last longer and it can be sanded multiple times if needed.
Engineered flooring s wear layer can be as thin as 1mm and gets as thick as 5mm.
On the contrary engineered flooring made from sliced and rotary peeled material is only going to produce thinner veneer layers about 2 mm.
