How to prepare your walls before installing your mural?
1-A clean, smooth surface for your wallpaper mural
The surface must be clean and smooth. Feel free to slightly smooth your wall with sandpaper to remove small imperfections (small grains of paint).
2-Ideal preparation: sealant B-I-N from Zinsser
For an ideal preparation, apply a coat of shellac sealer B-I-N from Zinsser, available in all good hardware stores (let it dry for 1 hour before installing your mural). When you want to remove your wallpaper mural, in 1, 5 or 15 years from now, pull the strips from the bottom up (no water, no steamer) and you will be able to reinstall it without any additional paste.
3-Very good preparation: An oil base primer (ideal to paint over dark or 2 colors wall)
A wall painted with an oil primer is fine too but you have to wait three days before installing your wallpaper mural. You will have the same benefits as the number 2 (your wall mural will be dry removable and you will be able to reinstall it without any additional paste). If you have a dark paint wall or 2 colors wall, oil base primer will do a better job than BIN to give you a light surface. Installing over dark paint might make your mural look darker if your mural has light colors.
4-Acceptable preparation: Wall painted with latex for at least 1 month
A wall painted with latex for at least 1 month (but ideally painted for more than 2 months) is acceptable, you will have no problem for the installation. When time comes to remove your wall mural, try to pull each strip from the bottom up but if you feel too much resistance, apply hot water over the whole mural, wait 7 to 8 minutes and try again. The strips should come off without any damage. You can reinstall the mural again but there will no paste left on the back of the strips. You will have to apply a clear wallpaper adhesive on the wall first, and install each strip as usual (soak in water).
5-Never: Install a mural over a latex primer
Never install a mural or any wallpaper over a latex primer, particularly when it is freshly done. You will not get any slip and it will make the installation more difficult. The removal will also be very difficult.
Our murals will stick well when hung directly over glass or mirror. You can also hang on melamine, ceramic or pre-finished panels providing you put 2 coats of oil base primer or one coat of primer-sealer B-I-N.
* Remember that with fast drying wallpaper primers are only diluted adhesives. It facilitates the installation but removal is very difficult.
