Peel & Stick = Piece of Sh!t

September 24, 2019


We’re seeing more and more of this peel-and-stick, supposedly “removable” and “repositionable” plastic wallcovering. Unfortunately, many homeowners read the lofty claims by the manufacturers and think it will be a perfect alternative to traditional wallpaper. It is not.

The stuff is awful – I won’t hang it, and most of my friends won’t either.

First of all, you don’t NEED an alternative to traditional wallpaper – you just need quality paper and someone who will properly prep the walls and then properly install the paper.

Getting back to P&S, the stuff is virtually impossible to hang. Imagine a 9’x2′ strip of Contact Paper, trying to position that on a wall without it wrinkling or sticking to itself, and then trying to butt another strip up next to it. Not gonna happen. It also does not “remove easily” … well, it does, but it will tear your wall apart in the process.

These homeowners had some guys doing other work in the nursery, and they said they could hang the wallpaper, too. They weren’t experienced paperhangers, and they weren’t up to the battle against this P&S. Virtually no one is.

First, they should have smoothed out the textured wall. Second, most P&S products spec that the wall should be sealed with a semi-gloss paint, which needs to dry and cure for two weeks. As you can see, this adds time and labor charges to the job.

I’m not sure why there are gaps at the seams (top two photos), but better prep would surely have helped prevent this. The large wrinkles are due to the inflexiblity of the material and its unwillingness to twist or stretch into position. With the baby on the way, the homeowner dad got desperate and used nails to try to tack down the curling paper.

The baby girl arrived, the parents lived with this wall for a while, and, when life settled down, they contacted me. I counseled them to forget the P&S and to choose a traditional wallpaper.

They zoomed in on this butterfly pattern by SuperFresco. This material is one of the newish non-woven materials, which contain a component of fiberglass and thus don’t expand or shrink, and won’t tug at the wall, so fewer worries of seems popping loose. These qualities also make it possible to dry-hang the paper, by pasting the wall instead of pasting the paper. I usually paste the paper, but on a single accent wall such as this (no toilets or sinks or fancy moldings to work around), pasting the wall works beautifully. It also saved me lugging my heavy, bulky work table up to this townhome’s third floor. 🙂

Removing the P&S paper was easy – it is strong and held together while I tugged it off the wall … I could do it all from the floor, without even climbing the ladder. Unfortunately, it took much of the paint along with it. So much for the “removable” claim.

It was still as sticky as the day it was born – so I rolled it all up and stuck it to itself and tossed the whole mess into the trash. Done and gone!

I skim-floated the wall to smooth it, sanded smooth, vacuumed, wiped residual dust off the wall with a damp sponge, and then rolled on Gardz, a penetrating primer-sealer, that also is a great undercoat for wallpaper.

All that (especially waiting for the smoothing compound to dry) took several hours. I think it was about 6:00 before I started hanging wallpaper!

Thin non-wovens generally go up with pleasingly invisible seams, and this one did, too. I was surprised to discover more than a few large wrinkles and bubbles. This could have been because the paper got twisted during installation, because the wall was smooth but not flat, because of some uneven reaction between the substrate and the paste which caused off-gassing (burps!), or some other reason. But it meant that I had to go over the wall several times, checking to be sure all areas were firmly secured to the wall.

The finished accent wall looks great! It’s a gentler pattern and a quieter color, and doesn’t hit you in the face as the original floral pattern did. There’s a little bit of fun shimmer in the scattered pearlized butterflies, and the blue-grey wings coordinate nicely with the three grey walls in the rest of the room.

Finally, Baby Girl is ready to move into her own room!

Cure Time – Paint Woodwork LONG BEFORE the Paper Goes Up

May 17, 2018


Why am I posting a picture of a can of trim paint? Because I found this in the room where I am to hang wallpaper today, along with a portable cup of wet paint and some brushes. This tells me that the homeowners were in the room last night, frantically painting all the woodwork in a large room with lots of framed openings and two walls of windows – LOTS of trim to paint.

Folks, this is not good. Woodwork should be painted carefully and slowly. First, the existing paint needs to be sanded or deglossed, and then wiped clean. I like to apply a coat of primer. Then the new paint can go up – but it should be brushed on carefully, paying attention to the direction of brush strokes and eliminating runs and drips.

But most important is that the paint needs time to dry. Not just to dry, but to cure. This can take several days.

This is important, because when I come along and put up the wallpaper, paste will get onto the woodwork. This is normal. No biggie. You just wiped it off with a damp rag.

But if the woodwork was not prepped properly, or if the paint has not had a chance to cure, it’s possible – probable – that the paint is not sticking tightly to the surface, and that wiping the paste off the woodwork will also take some of the paint along with it.

Best to plan ahead, read up on proper prep and materials, allow enough time to apply the paint properly, and then allow adequate dry / cure time.
