Under the Sea Wall Decals

Our decals are designed for easy application and clean removal on most walls. To ensure the best, longest-lasting results and avoid any surprises, please follow these tips carefully.

1. Test First — Your Free Sample

Every order includes a wall test sample. Apply it to the same wall and paint finish where your decals will go, leave it for 24–48 hours, then remove using gentle heat and a slow downward peel (flat against the wall, not outwards).

• If it applies and removes cleanly, you can install with confidence.
• If you notice bubbling or paint peeling, your wall may not be suitable — this can happen with fresh paint, old or flaky paint, porous or textured surfaces, or if a separate primer wasn’t used.
• Refunds are only available on unused products. Please see our Returns Policy for full details.

2. Wall Preparation

• For smooth application and best adhesion, your wall should be:
• Clean, dry, and smooth
• Painted with two coats of good-quality acrylic paint over a separate primer (avoid 2-in-1 paint + primer products)
• Fully cured for at least four weeks (paint may feel dry but still needs time to harden) and outgas, if this is ont followed decals can fall down as they cannot adhere properly
• Newly painted or poorly prepared walls can lead to bubbling or peeling when decals are repositioned or removed.

3. Paint Type Matters

Even professionally painted walls can cause issues if:

• A separate primer wasn’t used
• The paint is stain-resistant, washable, or Teflon-based (these resist adhesion if not primed correctly)
• The wall wasn’t sealed, or old flaky paint wasn’t removed before repainting
• The surface wasn’t sanded before repainting, so new paint couldn’t bond properly
• The paint is very old, brittle, or weakly bonded, which may cause lifting during removal

4. Prep Checklist

• Wash your hands
• Wipe the wall gently with a damp microfibre cloth
• Allow the surface to dry completely

5. Applying Your Decals

• Peel carefully from the backing sheet, handling the edges and avoiding touching the adhesive.

• Position on the wall and smooth firmly with your hands or a felt squeegee, working from the centre outward—pressure helps the adhesive bond. Be careful not to scratch or rub the the decal surface excessively as you can damage the print.

• For larger decals supplied in separate pieces: lay out the full design first, cut pieces apart (trim excess backing for easier handling), use painter’s tape to dry-fit/position, then apply one piece at a time, smoothing firmly as you go.

• If pieces overlap: align the patterns carefully. If the design looks slightly off, rotate the piece a little left or right until the overlap sits naturally, then smooth and press firmly to finish.

6. Repositioning

• Keep hands and wall clean
• Press firmly after repositioning
• Avoid shifting large sections at once, especially on delicate paint

7. Removing Your Decals

• Warm the decal with a hairdryer on low for 30–60 seconds
• Peel slowly from one corner, keeping the decal flat against the wall
• Use more heat if needed
• Gentle heat and a slow, downward peel are safest for delicate paint. On well-prepared, well-bonded paint, decals typically remove cleanly

8. Storage Tip

• Keep the original backing paper if you plan to move or store decals
• Corflute sheets (available at Bunnings or hardware stores) also work well
• Keep adhesive clean and free of dust to maintain reusability

9. Safety Reminder

• Press decals firmly, especially above cots or beds
• Check regularly and remove immediately if any edges start to lift

Important

Tiny Walls decals are designed to be removable, but damage-free results cannot be guaranteed in every case. Wall preparation, paint quality, and removal method all play a role. Testing with your sample first and following this guide will give you the best possible outcome.
