To apply sealer to wallpaper, follow these steps:
1. Prepare the wallpaper by cleaning it with a mild detergent solution and a sponge. Make sure to remove any dirt or stains.
2. Allow the wallpaper to dry completely before applying the sealer. This will ensure that the sealer adheres properly.
3. Use a paintbrush or roller to apply the sealer evenly over the wallpaper. Start from the top and work your way down, applying a thin coat.
4. Let the sealer dry according to the manufacturer’s instructions. This can take anywhere from a few hours to overnight.
5. Once the sealer is dry, you can hang pictures or other decorative items on the wallpaper without worrying about damaging it.
Applying sealer to wallpaper helps protect it from moisture, stains, and fading, extending its lifespan and keeping it looking like new.
When wallpaper is hung in a clean, dry area, it can be quite durable. However, if you plan to hang wallpaper in a damp or dirty area, it’s recommended to apply a sealer to protect the surface.
What is Wallpaper Sealer?
Wallpaper sealer is a product specifically designed to waterproof wallpaper and provide protection when it’s installed in moist or dirt-prone areas. Decorator’s varnish is a popular choice recommended by manufacturers, retailers, and decorators.
What You’ll Need:
-
Lint-free cloth
-
Decorator’s varnish
-
Shallow container or roller tray
-
Paint brush, paint roller, or foam applicator brush
Step 1: Ensure Wallpaper is Dry and Clean
If you want to seal the wallpaper immediately after installation, allow it to dry on the walls for one to two days. If the wallpaper is not newly installed, clean the surface with a lint-free cloth to remove any grease or dust.
Step 2: Mix the Sealer
Before application, ensure the varnish is well-mixed. Hold the bottle horizontally, with one hand on the cap and the other on the bottom of the bottle. Gently roll the bottle a few times to mix the ingredients without creating bubbles in the varnish.
Step 3: Pour Varnish into a Shallow Pan
Pour a portion of the varnish into a shallow pan or roller tray. The varnish will appear white when poured, but it will dry clear.
Step 4: Apply the Sealer
Use a brush, roller, or foam applicator to apply the varnish over the wallpaper. Maintain consistent brush strokes in the same direction, reloading varnish as needed. Ensure the entire wallpaper surface is covered with a thin layer of varnish, spreading it evenly.
Step 5: Add Additional Coats
Allow the varnish to dry for approximately two hours. Then, wipe the surface with a lint-free cloth and apply a second coat. Repeat the drying and wiping process, and then apply a third coat.
Step 6: Let Varnish Cure
Leave the wallpaper untouched for about a week to allow the varnish to harden and cure. Avoid scrubbing the surface until the varnish has fully cured.
Tip:
For better protection, choose a higher-gloss varnish like satin finish. If you prefer a matte finish, apply two coats of semi-gloss varnish followed by one or two coats of flat finish varnish.
Before applying the sealer to your wallpaper, test it first in an inconspicuous area of the room or on a scrap piece of wallpaper. Not all wallpapers may be suitable for varnish application.
