With tens of thousands of happy families, this is something we very rarely see, and when we do it almost always traces back to the wall surface. Because each design is printed in large production runs, a genuine manufacturing fault would show up across many orders at once, not as an isolated case. To date, we've never had a material or print fault behind this issue, it always comes back to the wall. Here are the five usual causes:
1) Your walls were not cleaned properly prior to installation. The dust and oil has repelled the adhesive on the decals
2) Your walls were not primed or are flaking (not a great paint job).
3) Your walls are textured and there is not enough surface area to grip.
4) Your walls were painted with Wash & Wear or Low VOC paint which is repelling the decal adhesive.
5) Your walls were recently painted (within 45 days) and the paint has not cured.
If you're using Wash & Wear or low VOC paint, or you're unsure about any of the above, a bonding primer can help improve adhesion on tricky surfaces.
If any of the above don't apply to you then contact us.
