Finding an installer
Thank you for bringing Grow House Grow’s wallpapers into your space! Professional installation is highly recommended. To find a paperhanger in your area, searching the Wallcovering Installers Association database is a great place to start. We also keep a short list of qualified installers on hand, and are happy to share it. On a related note, if you’re working with an installer who’s doing a great job, let us know! We would love to add them to our list.
Prior to Installation
It’s important to inspect your wallpaper before trimming or pasting, and to alert us of any issues before installation begins. Please note we are not responsible for wallpaper that has been hung on the wall, or damaged during installation. Grow House Grow’s wallpaper is hand silk screened with care using hand-mixed inks. Slight color, print, and alignment variation may occur and is considered normal.
Surface Preparation
Make sure walls are clean, patched, and even. Walls should be primed and prepped with a coat of sizing. Hanging blank stock or lining papers under our wallpaper is not necessary, but recommended. Its benefits include a smoother hanging surface (for older walls) as well as the control of seams and bubbles through moisture reduction.
For Dark Colorways
To minimize the appearance of seams when hanging a dark or vibrant colorway, choose a paint similar to the main background color of your pattern. Measure where each strip of wallpaper will meet on the wall, and paint the vertical area where the seams will align.
Additionally, we recommend tinting the edge of your trimmed paper with a small amount of diluted guache, colored pencil, crayon, or acrylic paint in a similar color (see “Trimming” below).
Layout
Trimming
Like many hand-crafted brands, Grow House Grow’s wallpaper will arrive with something most machine-made papers won’t have: a selvedge. This is a narrow 1.5 inch strip of unpatterned paper on each side of the artwork itself. Selvedge is important for several reasons:
Protection: The most important purpose of a selvedge is to protect your printed paper’s printed edge in shipping.
Alignment: The selvedge provides important information for your installer, such as where to join the pattern side-to-side and what direction the pattern should be hung.
There are two ways to remove your selvedge: the double cut, and the dry cut/table trim methods. For most installations, carefully dry cutting the wallpaper on a flat surface using a long straight edge and sharp razor blade is preferred. Be sure to replace your blades often for a clean cut.
Our wallpapers are designed to be trimmed just inside the TRIM mark on each side of the pattern. Please use this mark as a guide for the approximate trim line. Prior to trimming your paper, take note of the JOIN marks on each side of the selvedge. For the best match, Grow House Grow’s wallpaper should be aligned using the JOIN mark, both for straight-match and drop-match patterns.
For dark colorways, trimmed paper can be re-rolled and the edges lightly tinted to help camouflage the white ground.
Pasting
Clear, strippable paste works best with our wallpapers. Roman Pro-880 is a popular choice, and available at most hardware stores.
Using a brush or roller, carefully apply an even, thin coat of paste to the back of your wallpaper strip from the center outward, ensuring full coverage.
Booking
Also referred to as “baking,” this important step allows the newly applied paste to genty moisten your paper so that it will expand properly. Without creasing, carefully take one end of your pasted wallpaper and fold it in on itself, joining the end of the paper to the center of the strip. Keep the edges of the folded paper aligned, to prevent them from drying out. Repeat with the opposite end, folding over and meeting in the middle, paste-to-paste. You can now loosely roll this strip up to keep it moist as it continues to bake.
Take care to keep paste from smearing onto the paper’s printed surface. Should paste make its way onto the face of your wallpaper, remove it quickly and gently with a soft, clean, damp sponge.
Allow your wallpaper to book for 5-10 minutes. Booking times will vary according to ink coverage and the conditions of your space (for example, a very humid room may need less soaking time. Heavily inked patterns may need more soaking time). Do your best to be consistent with how long you book your wallpaper, so that each strip expands and dries at a similar rate. This will assist in the best pattern alignment.
Hanging your first strip
Take your fully booked wallpaper to the wall, and unfold the top portion of the strip. It can be helpful to do this step once you’re already on your stool or ladder. Press the top of your strip against the wall, leaving 2-3 inches overage along the ceiling (this is the allowance accounted for earlier, and will be trimmed off later). Using the palm of your (clean) hands and following your plumb line as a guide, begin to smooth the paper from the center out to the edges, working your way down the strip.
At the center of the strip, unfold the bottom booked portion, and continue to gently smooth and slide the paper into place down the wall. Once the strip is matched to the plumb line, smooth out all existing bubbles and air pockets from the center of the paper out. In some instances, areas of the paper may need to be pulled from the wall and repositioned to remove air pockets. When positioning your wallpaper, avoid pulling on its edges.
Take care when using smoothing tools not to burnish the paper; pressing too firmly with a wallpaper smoother can loosen metallics or scratch dark pigments. For delicate papers, keeping a high-quality wallpaper hanging brush or wallpaper roller on hand is wise.
Take care not to squeeze excess paste from the seams. Address any paste on the face of the paper as soon as possible. Paste that is allowed to dry on the paper’s surface may cause it to stain.
Once your strip is in position, using your smoother and a straight edge, trim the excess wallpaper from the top and bottom of the wall.
If necessary, use clean, warm water and a microfiber cloth to gently rinse your wallpaper of any remaining excess paste. Replace your rinsing water frequently.
Hanging additional strips
Taking your pattern repeat and match into account, cut your next strip of wallpaper, including 4-6 inches extra. Book your paper similarly to the first, and when ready bring your new strip to the wall. Starting with the top section of paper, use the palms of your hands to press your strip at the top of the wall, aligning the pattern where the “JOIN” marks were placed. Carefully slide the seams of the new strip and previous strip together, butting them well without overlapping.
Continue down the full length of paper, and once everything is properly matched use your smoothing brush to remove any pockets of air bubbles. Trim excess paper from top and bottom, wash away any excess paste, and continue to the next strip.
Once you’ve hung three strips, roll each of the butted seams with a seam roller using light pressure.
Inspect your strips for alignment and placement, and then continue with the rest of the space. Keep an eye on seams and re-roll gently as necessary. Allow for adequate ventilation and time for the paper to dry naturally. New wallpaper and pastes can have a light scent, similar to new paint, which will dissipate as it dries.
Cleaning + Maintenance
Using a soft cloth or duster every few months to keep the surface of your paper free from debris is the easiest way to keep your wallpaper maintained. Start at the top and work your way down to keep dust from spreading around. For small marks and stains, using a bleach-free household spray cleaner can assist in spot cleaning. Always use a soft cloth or sponge and a light touch to avoid burnishing, and test your preferred cleaner in an inconspicuous spot to ensure it won’t damage the pigments. For larger areas, the surface of the paper can be cleaned using warm water with mild dish soap and a microfiber cloth. Avoid hard scrubbing, and rinse well with clean, warm water.
Troubleshooting
WHITE EDGES ALONG SEAMS
There are two reasons why white may appear along the seam line. The first is the wall behind your wallcovering, which can peek through as the strips dry and gently contract. The second is the wallcovering itself: Because most wallpapers are produced wtih colorful ink on a white ground, this very thin white paper edge can be noticable along the seam after trimming–especially with darker colorways. There are several tricks to hiding color differences along the seam, especially when this is tackled prior to installation.
SOLUTION:
Before Installation
1. Determine the placement of your wallpaper strips on the wall, and paint the vertical areas where the strips will meet in a color similar to that of your wallpaper. This will help hide the wall underneath any spots where the paper contracts. Keep in mind you don’t need to paint the full wall (unless you want to!).
2. After trimming your wallpaper and prior to booking, roll your strip back up and carefully tint the cut white edge with a color similar to the main color of your pattern. For this process you can use crayons, colored pencils, pastels, markers, or diluted guache/a watercolor pen.
After Installation
Correcting a white seam after installation takes a little more patience, but don’t fret! Using a colored pencil (watercolor pencils are a little softer) or diluted watercolor/guache and a thin brush, you can lightly tint noticable areas. It can help to use a straight edge along the seam to control the fill, and it’s always wise to begin in an inconspicuous area as you get your technique down. We recommend selecting a color that’s a shade lighter than you think you’ll need, to prevent over tinting these spots. Keep in mind it might take some experimentation to land on the perfect color and method.
SEAMS CURLING
You’ve primed and sized your walls, pasted and booked your wallpaper, and after hanging your first drops you see the seams aren’t laying flat. One possibility could be the “differential” — this is the un-inked underside of the wallpaper absorbing mosture and expanding more quickly than the denser inked surface, which will push the coated side up into a curl. This is normal, and the more heavily inked a pattern is the bigger the differential will be.
SOLUTION:
– Ensure further strips are fully pasted all the way to the edge, and are rolled carefully edge-to-edge when booking to prevent seams from drying out more quickly than the rest of the paper.
– If needed, place pasted and rolled paper into a plastic bag with a light spritz of water when booking to help it fully relax. Adding one final light coat of paste after booking may be necessary.
– Adding a little paste to the wall underneath the seams and allowing it to get tacky before hanging your strips can help keep unruly seams in place.
– Consider the temperature and humidity of your space during installation. A very cold room will prolong drying times, while hot temperatures will shorten them. A very humid space can reactivate newly dried paste and allow once flat seams to lift.
– If necessary, hanging blankstock or liner papers underneath wallpaper can assist in controlling both seams and moisture.
SHINY SEAMS
If excess paste is allowed onto the surface of the wallpaper, it can leave a noticeable residue–especially on dark patterns. Additionally, shiny or discolored seams can also be the result of burnishing the paper when smoothing seams down.
SOLUTION
Care should be taken to quickly and gently wipe away any paste from the patterned surface using a clean, damp sponge or microfiber cloth. Paste that’s allowed to dry on the face of the wallpaper will be difficult to remove without damaging the print and will alter the finish.
To prevent burnishing, a gentle touch is required when pressing down seams and smoothing air bubbles.
POOR PATTERN ALIGNMENT AT SEAMS
Grow House Grow’s wallpapers are silk screened by hand, which means slight variation in color, linework, and pattern may occasionally occur. In most cases, these hints of the human hand aren’t noticable, but in order to minimize any differences in screen placement it is impotant to match your wallpaper at the “JOIN” mark noted on the selvedge.
This point denotes the screen repeat (as opposed to the pattern repeat, which might be smaller). By aligning your wallpaper at the screen repeat, you are ensuring the tightest overall pattern match for your installation. It’s important to consider this when measuring for your wall, to ensure this larger repeat is accounted for in your order quantity.
If you’re joining your strips at the “JOIN” mark and still encountering misalignment, you might have over-trimmed your wallpaper. Grow House Grow’s wallapers are intended to be table-trimmed just inside the trim line, and should be cut with a fresh straight edge for each strip.
