Why open the wallpaper with varnish

After opening the wallpaper with varnish, you can give the surface of the finishing material certain protective properties. Provided that the work is carried out correctly, the following advantages appear:

1. Paper and any other varnished wallpapers become moisture resistant. After the layer dries, the surface can be washed with a damp sponge.
2. Resistance to mechanical damage. The paint under the varnish layer does not fade, the top layer becomes impossible to erase or damage due to sticking tape or touch.
3. Appearance. Having varnished the surface of the wallpaper, the varnish changes the color of the surface, makes it glossy.

Before applying varnish to the wallpaper, you must take into account possible negative effects. Among them:

1. The material may become transparent and begin to shine through the wall.
2. If you cover the surface with glossy varnish, you can emphasize all the bumps and imperfections of the wall.
3. When drying, the paintwork material, decreasing in size, can undermine the wallpaper at the joints or voids.
4. If you need to remove the old wallpaper, then after opening it with varnish, this will become a real torment.

What trellis can be varnished

The following types of wallpaper can be varnished:

1. Paper. Water has a bad effect on the coating, so a special varnish VAK-A-104 is used for paper. It is allowed to use some varnishes on wood, for example, nitrocellulose NTs-228. The composition is easily applied with a soft bristle brush and dries quickly.
2. Liquid. The surface is hygroscopic and cannot be washed. The manufacturer of the coating usually also produces protective equipment. For liquid wallpaper, you can use matte varnish.. The protective layer will not change the appearance, but will allow you to acquire water-repellent properties.

3. Vinyl. They are made on a moisture resistant basis, so it makes no sense to apply a protective water-repellent layer.
4. Natural. Varnish can be used for bamboo and any other wallpaper. Durable material is able to withstand any paintwork. It is necessary to cover the wallpaper pasted in the bathroom and hallway with paintwork material.
5. Non-woven. Varnish is applied to a pre-painted surface. For work, paint and varnish is selected on a water basis.

Advice! If you cover the non-woven material based on the protective layer, it will become transparent. To prevent this, it is recommended to pre-paint the surface of the trellis.
