Wallpapering doesn't have to be complicated. After more than 25 years in the trade, I can tell you that success comes down to five things: a well-prepared wall, quality adhesive, a level laser, precisely cut strips, and finishing with a utility knife. Nothing more.
However, there's one factor that makes all the difference: the wallpaper itself. High-quality wallpaper, with a wide grammage, not only looks better—it's much easier to work with, applies better, and lasts longer. Don't skimp on the material. If you want to see how we work and the results we achieve, visit sevapintores.com.
Follow these steps, and you'll see that the result is professional, even if it's your first time wallpapering.
Step 1 — How to prepare for wallpapering
The wall is key. It needs to be clean, dry, and smooth. Use a level laser to mark the first vertical line—this is the starting point for everything. If the first strip is crooked, the rest will be too. The laser isn't a luxury; it's essential. At Seva Pintores, we've been preparing surfaces for over 25 years to ensure the result is always impeccable.
Step 2 — How to cut wallpaper correctly
Always measure with a margin—about 5 cm extra at the top and bottom. Use a long table, a metal ruler, and a sharp utility knife. A clean cut from the start prevents problems later. And remember: if the wallpaper has a pattern, align it before cutting. Have questions about which type of wallpaper to choose? At sevapintores.com, we offer free advice.
Step 3 — Surface preparation and gluing
Use quality adhesive—don't skimp here. Apply the adhesive evenly to the wall (for non-woven wallpaper) or to the wallpaper (for paper-backed wallpaper). The laser is still your guide: only apply adhesive to the area you'll cover with the first strip. If you prefer to leave it to professionals, Seva Pintores will take care of everything.
Step 4 — Applying the first strip
This is the most important strip. Align it perfectly with the laser line, from top to bottom. Don't stick it all at once—apply it gradually, making sure it stays vertical. The rest of the strips will align with this one. This is when you can tell if the preparation was good—as we always ensure at sevapintores.com.
Step 5 — Smoothing and preventing bubbles
Using the white plastic smoother, smooth from the center towards the edges. This expels air without creasing the wallpaper. Don't press too hard—use smooth, continuous movements. If any small bubbles appear, they usually disappear as the wallpaper dries. Not sure about the result? At Seva Pintores, we guarantee a perfect finish.
Step 6 — Wallpapering around outlets and switches
Run the wallpaper over the outlet without fear. With the utility knife, make an X incision over the center and carefully trim following the contour. Remove the outlet cover beforehand if you can—the result is much cleaner. These details are what differentiate amateur work from professional work, like the kind we do at sevapintores.com.
Step 7 — Sealing seams between strips
Using the seam roller, go over each joint between strips with gentle, even pressure. This ensures that the edges are well adhered and that the seams are practically invisible. Do not use the roller on textured or embossed papers—it flattens them. A wide, quality wallpaper, like those you'll find in our store, makes this step much easier. More info at sevapintores.com.
Step 8 — Final touches with an aluminum ruler and utility knife
With the aluminum ruler firmly against the skirting board or ceiling, cut the excess with the utility knife in a single clean motion. Change the blade frequently—a dull blade will tear the paper instead of cutting it. This detail makes the difference between good work and excellent work, like the kind you can see at sevapintores.com.
