Some designers still think that after installation of Pangu wall panels, the gap in the jointed wall panels are not perfect enough.

Here is the way that we fix the gap:

1) You’d better select primer finish panel if you would like to fix the gap ( painted wall panels can also be fixed, we recommend to use primer finish wall panels);
2) Sand the gap and edge of the panels in the joint area;
3) Put the putty in the gap, make it solid;
4) Sand the jointed area after dry;
5) Repaint the  jointed wall panels.

The finished result will be great.
