Can you Wallpaper Over Mass Loaded Vinyl? – Yes, Here’s How!

Yes, you can wallpaper over Mass Loaded Vinyl (MLV). However, it’s essential to follow specific steps and precautions to ensure the wallpaper adheres properly and remains in good condition. Here’s a guide on how to apply wallpaper over MLV:

1. Prepare the MLV surface: Make sure the MLV is clean and free of dust, dirt, or debris. Wipe the surface down with a damp cloth, and allow it to dry completely before proceeding. As with painting, lightly sand the MLV using fine-grit sandpaper (180-220 grit) to create a slightly rough texture, which will help the wallpaper adhesive adhere better. Remove any sanding residue with a vacuum or microfiber cloth.
2. Choose the right wallpaper: Select a wallpaper that is compatible with vinyl surfaces. Non-woven wallpapers are a good choice, as they are durable, breathable, and less prone to shrinkage. There’s a great selection of non-woven wallpapers on Amazon. Avoid using wallpapers that are too thin or delicate, as they may not adhere well or could be damaged by the MLV’s texture.
3. Apply a wallpaper primer: Before applying wallpaper, coat the MLV surface with a high-quality wallpaper primer designed for use on vinyl surfaces like Roman Eco wallpaper primer. This primer will create a smooth and even surface for the wallpaper to adhere to, improving adhesion and preventing potential issues. Allow the primer to dry according to the manufacturer’s instructions.
4. Measure and cut the wallpaper: Measure the height and width of the MLV surface and cut the wallpaper to size, allowing for a few extra inches on all sides for trimming. It’s a good idea to label the back of each wallpaper strip to ensure proper placement.
5. Apply wallpaper adhesive: Use a wallpaper adhesive specifically designed for use on vinyl surfaces like the Roman Heavy Duty Wallpaper Adhesive. Follow the manufacturer’s instructions for application. Apply the adhesive evenly to the back of the wallpaper strip using a brush or roller, ensuring full coverage to prevent bubbles or loose edges.
6. Hang the wallpaper: Starting in a corner or at a seam, carefully align the wallpaper strip with the top edge of the MLV and press it onto the surface, smoothing out any air bubbles or wrinkles with a wallpaper smoother or plastic scraper. Be sure to match patterns or seams as needed, and trim any excess wallpaper with a sharp utility knife.
7. Repeat for additional strips: Continue applying wallpaper strips, ensuring that patterns match and seams are properly aligned. Smooth out any bubbles or wrinkles as you go, and trim excess material as needed.
8. Allow the wallpaper to dry: Let the wallpaper dry according to the manufacturer’s instructions, usually for at least 24 hours. Avoid exposing the newly wallpapered MLV to moisture or extreme temperatures during this time.

By following these steps, you can successfully apply wallpaper over Mass Loaded Vinyl, adding a decorative touch to your soundproofing solution while maintaining its effectiveness.
