Overlap and double cutting
Commercial wallcovering is untrimmed. Both match and random patterns must be overlap and double cut. When applying the second strip, it should be applied to the edge of previous one and match design. For uni color or wallcovering no need to match, overlap the two strips about 4-5 centimeters and use sharp knife to cut in the middle. To make cutting line straight, use steel ruler to avoid knife derailing.
Take out the two strips cut, press the seam between two strips and use clean wet towel or sponge to clear excessive adhesive on surface. Avoid adhesive contacts face side when applying deep texture, mica-abundant and dark color wallpaper. Can use special seamless tape, stick it on overlap area and take it out after cutting edge, later use seam roller to smooth the edges.
