  • To measure correctly, the bar is measured between two corners. In this case, for internal corners, the length is measured from the internal elements, and the distance from the external corners is measured from a point that is at a distance equal to the width of the plinth deep into the room from the internal.
  • When installing foam plinths at the junction between the wall and the stretch ceiling, glue is applied to the part of the plinth that is in contact with the wall, and not with the canvas.
  • The final fixation of the skirting board is carried out after fitting the angle of the adjacent plank to it.
  • If the wall, ceiling and floor have a right angle, it is easier to adjust the planks below, laying out the parts on the floor or on the prepared table.
  • Small gaps remaining in the corners are putty.
  • Particular attention should be paid to the installation of rare wood skirting boards. In this case, puttying the gaps the expected result, most likely will not work. A bright spot will appear on the background of the texture.

When proceeding to the next corner, carefully measure the distance that remains and cut off the missing part, everything should be very accurate.
