Installation Tips: 1. During the packaging and transportation of the product, the tape may foam. This is normal and will not affect normal use; 2. If the wall is uneven, peeling, or damp, you need to deal with the wall before it can be used; 3. Buyers who have wall cloth or wall stickers on the wall should use nail-free glue or glass glue to ensure the effect of the paste; 4. Please make a mark in advance to avoid repeated sticking, which will affect the stickiness; 5. Please clean up the dust and water stains before installation; 6. Before installation, you can use a hairdryer to heat the adhesive strips for better sticking effect; 7. During the installation process, it is more ideal to use multi-angle bevel shears or to match corner decoration; 8. Please don't use your hands to test the adhesiveness of the adhesive strip, which will affect the stickiness; 9. Don't touch it immediately after installation, it will reach the best viscosity after 24 hours. Please note: 1.
