Seamless triangle Wallpaper

• Non-Pasted is the traditional paste-the-wall option and the most durable for permanent installations.
• Pre-Pasted requires water to activate and is a good middle ground. You can also remove it cleanly by reactivating the adhesive backing with water.
• Self-Adhesive (peel-and-stick wallpaper) is the best option for renters, curved surfaces, and quick changes – it removes cleanly with no residue (with proper wall preparation beforehand!).
• Grasscloth is a great option if you want to add a unique texture and a more organic feel to your home.
  

Yes, we highly recommend ordering a sample before purchasing wallpaper for your entire wall. A sample lets you see the actual colors, texture, print quality, and material in your space and lighting.

Use the wallpaper calculator on this page – enter your wall width and height, and it will tell you how many panels to order and show the layout. 

We recommend adding 1–2 extra inches (2–3 centimeters) to your measurements for trimming and any mistakes. 

Yes! Our wallpapers are suitable for DIY installation. Self-Adhesive and Pre-Pasted options are particularly beginner-friendly, while Non-Pasted and Grasscloth require a little more preparation and care.

For best results, follow the installation instructions for your chosen material and take your time when positioning each panel.

For the best adhesion and finish, we recommend installing wallpaper on  smooth, clean, dry, and properly prepared surfaces. Lightly textured walls may work with some materials, but heavy or uneven textures can prevent the wallpaper from adhering properly and may remain visible through the finished wallpaper.

If you're unsure about your wall, we recommend ordering a sample and testing it on a small area before placing a full order. You can also email us a photo of your wall at support@lagrandclassique.com, and we'll be happy to help you determine whether our wallpaper suits your surface and which material is the best choice for you.

Yes, you can use Self-Adhesive Wallpaper and Pre-Pasted Wallpaper in a bathroom as long as the room is well ventilated and the wallpaper isn't exposed to constant or direct water. 

Before installation, make sure the wall is completely dry, clean, and properly prepared. Do not install wallpaper inside a shower or on surfaces with ongoing moisture exposure.

It’s not recommended to use Non‑pasted and Grasscloth Wallpaper in high‑moisture areas, including bathrooms or kitchens, as water and humidity can damage the material.

Yes. All our wallpaper materials are PVC-free and made with eco-conscious materials, making them a great option for nurseries, children's bedrooms, playrooms, and other spaces throughout your home.

Self-Adhesive and Pre-Pasted options are designed to remove cleanly, as long as the surface was properly primed.

Non-pasted and Grasscloth can be removed as long as you use a strippable adhesive such as PRO-880 Ultra Clear® during installation. 

As with any wallpaper, follow our hanging guide (https://lagrandclassique.com/pages/wallpaper-hanging-guide) and test a small area first. 

Wallpaper is printed in CMYK, while screens display colors in RGB, so slight differences in color, brightness, and tone are normal. Screen settings can also affect how colors appear.

We strongly recommend ordering a sample of your exact wallpaper combination before committing to a full order.
