1. Wall surface and wall surface preparation
According to the technical guidelines for wallpapering and pasting work the surface to be covered must be dry, sound, uniformly absorbent, clean and smooth.
Remove old wallpaper and any unsound coatings completely. Close any holes or irregularities with plaster-based filler, and smooth the surface.
In order to make absorbency consistent and reinforce old plaster surfaces or new plasterboard surfaces, prime the surface with water-based plaster sealer. Prime new gypsum plaster and firm, highly absorbent surfaces with diluted wallpaper paste. If the surface is smooth but not absorbent, you can make the surface compatible with wallpaper by applying a nonwoven liner with special-purpose wallcovering paste.
2. Paste and hanging
For paperhanging, we recommend using solvent-free non-woven glue.
For paperhanging on the wall: Apply the wallpaper paste evenly in a sufficient amount to the base surface and lay the cut lengths of wallpaper dry into the bed of adhesive. Please read the adhesive manufacturer’s instructions for use.
Using a pasting machine: Paste solvoprint performance wallpaper using a pasting machine, fold it and hang it immediately without allowing for a soaking time. Use non-woven adhesives in the way of manufacturer recommendations.
Please read the manufacturer’s wallpaper glue instructions.
Hang Neschen performance wallpaper perpendicular, with the lengths butt jointed to each other. Before you start paperhanging on the wall ensure, that the printed surface/ink are cured and dried. Basically, a vertical paperhanging on the wall “away from light” is recommended. For prints with clean cut edges, the edge of one strip is butted up against the edge of the adjoining strip. Please note, after printing of the length of wallpaper, approx. 0.3% warping would be expected.
For overlapping printed wallpaper strips, cut off the white edges up to the pattern when the wallpaper is dry. Then align the stripes on the wall in the area where they overlap and press down with a rubber roller or a soft brush, to remove any air bubbles. On each drop, the final sweep with the rubber roller should be applied horizontally in the direction of the free edge (working direction). If a double seam cut is necessary, it will be possible to use the special-purpose knife.
For a clean seam, cut through the two layers of overlapping wallpaper in one cut, remove the wallpaper adhesive residues and finish off with a seam roller. Press excess wallpaper on ceilings, skirting boards, windows etc. into the corners with a plastic trowel and trim with a Stanley knife. Ensure the wall covering does not overlap. Immediately remove any traces of adhesive on the surface with a soft, slightly damp cloth.
Neschen performance wallpapers are extremely hard-wearing. For heavily used environments such as catering establishments, swimming pools or event venues, we recommend coating the wallpaper after hanging with a high-quality clear varnish to protect the print.
Don’t use dispersion adhesive, because a negative influence on the printed surface is to be expected! We recommend the use of protective gloves (soft cotton) when wallpapering, to protect the high-density inks.
Prevent any emerging paste from getting onto the front or else stains and differences in gloss may occur. If paste does get onto the front of the paper, remove it immediately with a clean cloth and clean water.
A golden rule when wallpapering is to avoid heating the room too much and prevent draughts during the drying process or else seams may open. This information only consists of general recommendations.
