Before you start wallpapering, read this

Preparation is the foundation of a successful result. The effort you put in here will always pay off when you start wallpapering. Meticulously performed preparation work makes wallpapering easier and the result better looking.

What type of wallpaper have you bought?
· Non-woven, a so-called EasyUp wallpaper: here you apply the paste directly to the wall. Cut your strips to size and mount them on the pre-pasted wall. Be careful with any pattern matching. (More on that later). Use non-woven paste, e.g., Hernia NW.
· Paper wallpapers: you apply the paste to the back of the wallpaper and let it "soak" for a little while. When mounting on the wall, place it with an overlap of approx. 5 mm because it shrinks slightly as it dries. Use paste intended for paper wallpapers, e.g., Hernia 1870.
· Photo wallpapers, many imported wallpapers, or digital wallpapers that have more transparent paper: here you must first paint the wall to get a homogeneous base for the wallpaper. Otherwise, color shifts in the substrate will show through and lead to a poorer result. Use non-woven paste here as well, e.g., Hernia NW.

Before you begin.
· Always check that the wallpapers you received are the right kind and that the batch number is the same on all rolls that will be in the same room. We always check this carefully before we send the wallpapers to you, but mistakes happen.
· Check that the rolls have no defects; if you discover any, contact us so we can send new rolls. Wallpaper manufacturers do not approve claims once the wallpaper is on the wall; it must be claimed before hanging.

Now it's time to start.
· The wall must be firm and clean, with no loose wallpaper flakes or filler dust.
· If you have not removed all old layers of wallpaper, which is recommended, it is a good idea to prime the wall with insulating/sealing paint. You do this to reduce the risk of the old wallpapers underneath bubbling. Suitable paint is Sigma Isotop Primer or Jotun’s wallpaper primer. Once painted, sand lightly and wash down with paint cleaner.
· Where applicable, prime the wall, preferably white. The entire wall must have the same shade if the wallpaper is of the type mentioned in point 3 above.
· Sometimes "reverse hanging" occurs; make sure all wallpapers are hung in the right direction. If reverse hanging is required, this is marked on the roll label or with a loose note inside the roll.
· For non-woven, digital, and photo wallpapers, apply the paste with a brush at the ceiling and skirting boards and roll the paste onto the wall. Apply paste for 2–3 strips (approx. 1–1.5 m) at a time. If you can "draw" in the paste with your fingers without it dripping or running, you have the right amount of paste.
· Start from the top, press the wallpaper into place, and check that it is plumb, i.e., completely straight. Small deviations at the beginning become large deviations at the end. If the wallpaper ends up crooked, loosen the whole strip and start over. Work from top to bottom with a wallpaper tool or brush. Make sure all air bubbles are gone. Do not press so hard that paste comes out on the front; if it does, wipe it off immediately with a wet cellulose sponge.
· For non-woven, digital, and photo wallpapers, hang the next strip edge-to-edge. Guide the strip into the correct position with your palms; do not pull on the edges of the strip. If not all angles are 100% straight, pattern matching can sometimes feel tricky. Keep in mind that when you enter your newly wallpapered room, you perceive the whole, not the small deviations you see in detail while hanging. If deviations in the pattern occur, match the pattern at eye level. In odd angles (e.g., 45°) or at doors and windows, it may be easier to cut the wallpaper vertically and apply narrower strips, then match the pattern as closely and well as you can. The overall impression will still be perceived as very good.
· When you have hung 2–3 strips, check the result for color differences or other faults; if any occur, contact the seller for possible claims or advice.
· If you have bought a wallpaper with strong and intense colors, these are slightly over-pigmented and can rub off. Use a wallpaper brush or other soft tool. Press the seams with a light hand and try to avoid getting paste on the front. Should this happen anyway, wipe it off carefully with a wet cellulose sponge. Do not use textile rags, dishcloths, or similar, as these act like sandpaper and destroy the wallpaper; this causes the printing ink to come off and the seams to become lighter. If the wallpaper is also embossed, this can be ruined while the wallpaper is damp. Cut the wallpaper at the skirting board with a sharp wallpaper knife. Change the blade often; a dull blade tears the wallpaper.
· When finished, ventilate and maintain a normal room temperature until the wallpaper has dried thoroughly.

If something is wrong with your wallpaper.
· For any claims, all roll labels must be returned together with opened and unopened rolls or sample pieces of the wallpaper that clearly show the fault. Installed rolls are considered approved rolls and cannot be claimed.
· Always stop working if material defects are discovered.
· If you have hired a professional to do the job, this is especially important as compensation for labor costs is never provided.
· Defective rolls are replaced with new rolls; labor costs are not credited.

Faults that can occur which are not due to the wallpaper
· Blistering
· Edge curling
· Gaps in the seams
Printing errors, damage to paint or paper, misprints, or similar will be replaced with an equivalent amount of flawless wallpaper upon presentation of the defective item and roll labels.
Costs for wallpapering or painting work are not compensated, nor is compensation provided for loss of time or other indirect damage.
