How to Install
Test Sample (included free in every order)
- Choose a spot: Wipe clean with a damp microfiber cloth and let dry.
- Apply the sample: Peel, stick, and smooth down by hand.
- Wait 24–48 hrs: Check adhesion and paint hold.
- Remove with gentle heat: Warm with a hairdryer and peel slowly downwards, flat against the wall.
If the sample works, your decals will too. Fresh paint (30+ days), textured/porous walls, or poor prep may affect results.
Quick Install Guide
- Start with clean, dry, smooth walls and fully cured paint (30+ days after painting).
- Peel the decal from the backing.
- Position and smooth firmly with your hands or a soft squeegee.
- For larger pieces, cut and apply individually for easier alignment.
Most installs take just minutes.
Removal
- Warm with a hairdryer and peel slowly downwards, flat against the wall (not outwards).
Removal Guide
Warm a hairdryer on low heat over the decal for 30–60 seconds, then peel slowly from a corner in a downwards direction, keeping the decal as close to the wall as possible, Don't pull outwards from the wall. Heat again if needed.
Materials & Wall Types
Our decals are printed on premium, non-toxic polyester fabric with a soft matte finish — never vinyl. They use a removable, water-based adhesive so you can reposition during install and peel away when you’re ready for a change.
Best on: Smooth, fully cured painted walls finished with quality primer and acrylic paint.
Not suitable for: Textured walls, raw plaster, brick, bathrooms, or high-humidity areas.
Tip: For freshly painted walls, wait at least 30 days before applying. Avoid chalky, powdery, or flaking surfaces.
