·Tolerance of level difference is within 3mm which measured by a 2 metter rule
·All ground should be no cracks.IF there is cracks or not level,then must fill and level up well.

2.Checking the Materials
Differences of width(tolerances) may exist between the rolls.
It is advisable to check the material for defects before installation.If there are visible defects, you should inform Aceflor before using the material.
When unloading the materials from containers or trucks, take care of packing,especially the surface of flooring.Please roll or move the rolls in the direction that we roll the flooring,not in reverse direction.
Please make sure all rolls stand up in the installation facilities if the venue or subfloors are not ready for the installation.
