What Type Of Glue To Use On Wallpaper

When it comes to wallpaper installation, using the right type of glue is crucial for a successful and long-lasting result. Choosing the wrong glue can lead to peeling, bubbling, and other defects that can ruin the look of your wallpaper and even damage your walls. Therefore, it's essential to know what type of glue to use on wallpaper and how to apply it correctly.

There are several types of wallpaper glue available on the market, each with its own strengths and weaknesses. The most commonly used glues are:

1. PVA Wallpaper Glue - Polyvinyl Acetate (PVA) glue is a water-based adhesive that is ideal for porous surfaces such as wallpaper. It dries clear and creates a strong bond between the wallpaper and the wall. PVA glue is easy to use, easy to clean up, and non-toxic, making it the perfect choice for DIY home projects. It is also resistant to moisture, which is a plus.

2. Cellulose Wallpaper Glue - Cellulose wallpaper glue is made from wood pulp and is also a popular choice for wallpaper installation. It's easy to mix and apply and creates a strong bond with the wallpaper. However, it takes a bit longer to dry than PVA glue, and it's more challenging to clean up.

3. Ready-Mixed Wallpaper Paste - Ready-mixed wallpaper paste is a convenient option for those who want to avoid the hassle of mixing their own glue. It comes in a tub or a bottle and is ready to use immediately. However, it's more expensive than PVA or cellulose glue, and it might not be as strong as other types of glue.

4. Vinyl Over Vinyl Wallpaper Adhesive - This type of glue is specially designed for applying new vinyl wallpaper over existing vinyl wallpaper. It has a strong bonding power and ensures that the new wallpaper won't peel off.

When choosing a glue for your wallpaper, consider the type of wallpaper you are using, the surface you will be sticking it to, and the room's humidity level. In general, PVA glue is suitable for most types of wallpaper and surfaces, but if you are using a heavyweight wallpaper or have a humid room, you might need a stronger adhesive such as vinyl over vinyl wallpaper adhesive.

Before applying the glue, you need to prepare the walls and the wallpaper. Make sure the walls are clean, dry, and free from dust or debris. If the wallpaper is pre-pasted, activate the adhesive by wetting it with a sponge. If it's not pre-pasted, apply the glue to the back of the wallpaper using a brush or a roller, making sure to spread it evenly.

When hanging the wallpaper, start from the top and work your way down, aligning the edges carefully. Smooth out any bubbles or creases using a wallpaper roller or a clean, damp cloth. Allow the wallpaper to dry completely before trimming the excess using a sharp knife.
