Reasons and Solutions

Jerry-built
In order to request the fast efficiency, the construction unit often omits the correct construction method, such as the caulking process. In general, the correct construction method is to paint a layer of AB glue at the junction first, then, do the caulking process. Finally, use the sandpaper to make the surface smooth. But some construction units will omit the AG glue process. That’s why the cracks will show up easily.
-
Thermal expansion and contraction
If the density of PU moulding is insufficient, it may cause the expansion and contraction. The cracks will cause broken and influence the beauty of the interior. You should choose high-quality PU moulding to decorate your house, such as Goodware PU decorative materials.
