Thirdly, the problem of moisture content. If the moisture content of wooden flooring is not perfectly control, there will be seriously deformation of the flooring, such as cupping, banana, and bending. Usually, occasional bending problems could be selected and taked away when inspect, but if the bending exceed a certain proportion of unacceptable, and there is reason to refuse delivery, the manufacturer will have to re-processed these planks. The main point here is that some buyers do not fully understand the processing technology, factory processing can use some methods to have deformation of the floor temporarily restored to a straight state, however, when the floor eventually arrived at the work site or will resume bending state, then the installation will be problem. Conventional pre-shipment inspection can not completely eliminate such problems. can problems be found in time and hidden dangers be avoided.
Fourthly, the problems of processing accuracy, such as the height difference, the tightness of the tongue and groove, the pointed seam, the straightness, and the assembling of locking system, noise when walking on the installed flooring. These problems require a high level of equipment and experience of the workers . buyers should take care about these when visiting the factory, anyway, if your inspectors familiar with the workers, when any wrong occur, it could be solved on the spot.
The above quality problems can be basically controlled before shipment, but there are also some problems that are not easy to find before shipment:
1, the glue failure problem of engineered flooring is a very serious problem, which always cause a large amount of claims. However, problems generally appear in the pressing process, which requires professional inspectors to find and correct in time.
2,The coating cracks from the knots when the flooring installed and used. This problem may be due to the use of the floor environment, but most of the cases are due to the poor quality of raw materials for floor processing. Some times the manufacturer using the low quality coating not according to the agreement, so it is better your inspector will be there when painting.
