Wallpaper and YouTube Don’t Mix

December 31, 2017


This West University mother of young children went to YouTube for some primers on how to hang wallpaper, and then, along with hubby, spent a 3-day weekend tackling the powder room redo project. They didn’t do a horrible job (first three photos), but there were some things that must not have been covered on YouTube.

First, and probably most important, the walls should have been primed with a product designed for wallpaper.

Second, seams should be butted, not overlapped.

Third, wallpaper should not be wrapped around the door moldings, but trimmed at the base.

Fourth, I’m not sure what’s going on with the cuts at the baseboard. I think the room had seen a number of redecorating efforts, and that the baseboards took a bit of a beating in the process, leaving a surface that wasn’t smooth and wasn’t willing to hold on to wallpaper.

I stripped off their wallpaper, patched bad spots, sanded the walls, then primed with Gardz, a penetrating sealing primer that bonds together porous surfaces and that is also a good base to hold wallpaper.

The rest of the photos are of the room after I hung the new paper.

This product is a pre-pasted, paper-backed, solid vinyl material. It happens to be one of my least favorite kinds of wallpaper. The homeowner chose it because she has young children and the vinyl is reputed to be more water-resistant and durable than other types of wallpaper. If she had consulted with me before she bought her paper, I would have steered her in another direction.

It’s true that the vinyl surface is resistant to water, and it’s more resistant to stains than a paper-wallpaper. But that doesn’t make the product wonderful.

The main problem is the paper backing. This stuff is not horrible, but it does have a reputation for curling a tad at the seams (do a search on my blog for previous posts). Humidity (such as in a bathroom with showering) can cause increased curling at the seams. Any water that falls on a cut edge of the paper (along backsplashes, seams under hand towels, etc.) can wick into the paper backing and cause it to expand, which will cause the seams to curl.

To reduce the potential for seam curling, I used a special pasting process (rather than following the manufacturer’s instructions). And I ran a bead of caulk along the top of the backsplash (see 4th photo – the caulk will be clear when it’s dry) to prevent splashed water from wicking up under the wallpaper.

My trim cuts along the baseboard looked better than the homeowners’, but I still felt the baseboard was compromised somehow and that wallpaper did not have a good surface to grip ahold of. So I ran a bead of caulk along the top of the baseboards, too.

This wallpaper is by Exclusive Wallcoverings, a British manufacturer. It is a faux grasscloth, and, unlike true grasscloths, it is pretty water- and stain-resistant, and it has a pattern that can be matched. In fact, the close-up photo above shows a seam – and I’ll bet that you can’t find it! The pattern number is FD44143

Next time around, when a mom has concerns about her kids touching or splashing the wallpaper, I would suggest she consider one of the newish non-woven products. Or, better yet, a scrim-backed (woven fabric-backed) solid vinyl product, such as something from the Thibaut brand Texture Resource line, particularly Volume 4. Everything in that book is beautifully textured and realistic, and virtually indestructible. Do a search here to see my previous posts.

Mildew!

December 13, 2017


You can clearly see the mildew on the wall that was revealed when I removed the wallpaper. It shows up as the black rings / circles.

The mildew was caused by moisture trapped in the wall by both a leak in the roof or siding, and a leak from a bathroom that crept under the floor – compounded by being trapped inside the wall by a solid vinyl wallpaper that would not breathe or allow air to pass through. Another reason to avoid paper-backed solid vinyl wallpaper.

Note: This issue was with mildew. Mildew is not nearly as dangerous as mold. Still, the homeowner took the contractor’s advice and had the drywall completely removed and replaced.

Stay Away From Paper-Backed, Solid Vinyl Wallpapers

Solid vinyl wallpapers are often marketed as “kitchen and bath” papers, because they are somewhat more washable than other types of wallpaper, and because splashed water will run right off the vinyl (plastic) surface.

However, I find just the opposite with these solid vinyl papers, particularly the pre-pasted, lower-priced ones.

The seams generally never look great to begin with. Then the porous paper backing tends to absorb moisture, such as humidity in a steamy bathroom. When the paper absorbs moisture, it expands, and when it expands, it has nowhere to go but to push away from the wall – causing a curled seam. Often the top vinyl layer even starts to delaminate from the paper backing.

This is not a “loose seam,” and it cannot be “reglued.”

Humidity is a factor, but so is improper wall prep. Usually, when there are curling seams like this, the previous installer neglected to prime the walls, and just hung wallpaper on top of the bare drywall.

In the two photos with paper curling away from the top of the baseboards and from the top of the granite countertops, it is not sticking because the surface beneath it is slick – overspray of gloss paint from the woodwork, caulk used around the top of the backsplash. Again, a primer would have prevented this.

I also like to run a bead of caulk around the top of the backsplash, to prevent splashed water from being wicked up under the cut edge of the wallpaper, which would cause curling.

I have blogged a number of times about curling seams due to crummy paper-backed, pre-pasted solid vinyl wallpapers. Choose some key words and do a Search here to read more.

Killing Mildew

November 2, 2017

Yeowee … this wall has a lot of issues with torn Sheetrock (the dark brown areas), but more important – the black stuff that you see in the top photo is mildew.  Not good.  Mildew is a living organism, and it can grow and grow.  It’s powdery, and so as it spreads across the wall, it can separate from the wall (delaminate), which means that the wallpaper is at risk of falling off the wall.  Mildew can also travel right through wallpaper, creating a ghost-like shadow of dark – or sometime pink – discoloration.

Mildew is usually caused by moisture.  It’s not clear what caused the problem in this powder room in a 1957 home in the Tanglewood area of Houston.  It could be a leak in the wall (pipe, window, roof, lawn sprinkler outside hitting the wall).  Or it could be that the solid vinyl surface of the previous wallpaper prevented air from getting to the backing, and so that it could not dry out, and then it held dampness against the wall – which created the perfect breeding ground for mildew.

Getting rid of mildew requires a few steps.  First, it must be wiped and scrubbed with chlorine bleach, then rinsed clean.  Once the wall is dry, a coat of a quality stain-blocker is applied.  I like oil-based KILZ Original, but other options include Zinsser’s B-I-N stain blocker.

Once the stain blocker is dry, the wall can be coated in a wallpaper primer.

Peeling Paper Caused by No Primer Underneath

These wallpaper jobs are failing, mostly due to the fact that the previous installer did not prime the walls before hanging the paper.  With no primer, the walls are porous and will suck paste off the paper, leaving little to hold the paper on the wall.   Bathroom humidity has exacerbated the problem.

The top photo shows a paper-backed solid-vinyl paper, which are usually pre-pasted and lower-priced.  These are particularly bad for humid areas, because the paper backing tends to absorb humidity, expand, and push away from the wall.

The striped paper is a paper, which usually perform well and hold tightly to the wall even under humid conditions.  But with no primer to seal off the thirsty wall underneath, the paper has nothing to grab ahold of and is curling away from the wall.

In fact, when I went to strip the paper, it came off in whole sheets with just a gentle tug.  I had the entire bathroom stripped in, literally, about two minutes.

Before hanging the new paper, I will be sure to prime the walls.  The last photo (bottom row) shows two of the primers I will use.  The Pro 977 works on walls that are clean and have been previously sealed.  The Gardz is a penetrating sealer that is good for porous walls like flat paint, new drywall, or newly skim-floated walls.  It will also work on walls that have a bit of residual wallpaper paste because it seals it and makes it inert.

 

Mildew Found Behind Wallpaper

September 20, 2017

I removed a strip of paper-backed solid vinyl wallpaper from the wall over a shower in a room used by two teenagers.  The type of paper (one of my least favorites), the humidity from the hot and heavy shower usage, the  lack of primer used by the previous installer, and an exterior wall that most likely had some moisture problems, all added up to a recipe for mildew.

I used bleach and then another mold / mildew product to kill and remove the mildew, then went over it with an oil-based stain-blocking sealer called KILZ.

Over the KILZ, I added a coat of wallpaper primer.  The two primers that I use most are the large cans in the last photo, and they each are used for different circumstances.

 

Homeowner Tackled the Wallpaper Install – So, How’s That Working Out for You?

The homeowner tried tackling this wallpaper installation herself, without even consulting so much as a YouTube video. She didn’t do an all-out bad job, and the paper is still stuck to the wall after three years. But there are a number of things that were done incorrectly.

1. Walls were not primed with a wallpaper primer

2. Caulk should have been run around the top of the backsplash

3. Paper was wrapped around the edge of door moldings and not trimmed.

4. Seams were overlapped

5. Overlapped areas were not secured with a “vinyl-over-vinyl” adhesive.

6. Pattern was not matched.

7. And, last but very important – a poor choice of wallpapers.

I am not a fan of paper-backed, solid-vinyl wallpapers, especially the pre-pasted, lower-end products. Do a Search here on various terms, and you will learn a lot about the material and its poor performance. IMO

In the meantime, when I take on this job, I will remove all the old paper, scrub the walls to remove paste residue, fix any dings in the walls, prime with an appropriate primer, hang the paper properly, by matching the pattern, butting the seams, and trimming correctly along baseboards and door moldings, etc., and, when finished, I will run clear caulk along the top of the vanity and other key areas, then give the family my “lecture” about leaving the door open and using the exhaust fan and avoiding long steamy showers.

Stripping Off The ’90’s To Reveal – The ’70’s

July 20, 2017

Today I stripped paper off the walls of a typical entry in a typical ’60’s / ’70’s-era home.

The paper I removed was a pre-pasted, paper-backed, solid vinyl in a striped design. This is a typical pattern, and a typical type of material, for that time.

Under it was the original paper from when the home was built in the ’70’s. If you remember, that was back in the days of Harvest Gold, Avacado Green, orange, and Flower Power. This vintage paper has three out of the four!

After all these years, and despite having been covered up by the vinyl wallcovering, the orange paper was in perfect shape – tight to the wall, and brilliantly colored. The vinyl paper, on the other hand, was curling at the edges and was discolored.

This is partly due to age, but mostly due to having been improperly installed… previous installer did not remove the old wallpaper, and did not prime the walls, plus these pre-pasted, paper-backed, solid vinyls are just not good papers.

This home is in the Kirkwood / Briar Forest area of Houston.

Brightly Nautical Wallpaper in a Master Bathroom

I didn’t get pictures of the original wallpaper, but it was a pre-pasted, paper-backed solid vinyl (my least favorite kind) and had been poorly installed on un-primed bare drywall. Over the 12 years it was up, humidity from the bathroom had penetrated the seams and caused the paper to curl.

This paper (not vinyl) wallpaper, hung over properly primed walls, will cling tightly to the wall and perform well for many years to come. Plus, it’s bright and pretty and adds a lot of life to the room.

One shot shows the oceanic paper in the main room, looking into the potty / water closet, which has been papered in a coordinating yellow striped pattern. I really like using two papers this way. See tomorrow’s post for pics of the potty room.

This home is in West University Place (Houston). The wallpaper pattern is #839-T-6701 by Thibaut Designs, and was bought at below retail price from Dorota Hartwig at Southwestern Paint on Bissonnet near Kirby.

Spring Time in a Powder Room

I forgot my camera yesterday, the day I stripped off the old paper and prepped the walls, so I cannot show you the 15 year-old wallpaper with its curling seams, due to 1.) being an inexpensive paper-backed solid vinyl wallpaper (my least favorite kind – do a Search here), and 2.) the previous installer did not prime the walls but instead hung the wallpaper directly on the new home’s bare Sheetrock, and 3.) age, heat, and humidity. The pattern, however, was not too dissimilar to this one, being a sort of “impressionistic painting” design in the same blue, pink, yellow, and green color scheme.

Anyway, the new powder room looks fantastic. The colors are similar to what the homeowner had before, but this wallpaper should hold up much better. The material is paper (not vinyl), and will hug the wall tightly. I removed every scrap of old paper and sealed the walls with a penetrating sealer named Gardz, and then primed with a wallpaper-specific primer called Roman’s Ultra Prime Pro 977.

On top of this good foundation, the new wallpaper is a pre-pasted, raised-ink paper by Thibaut, and is one of my favorite products to work with, and I also love it’s dependable performance down the road. The pattern is #6936, and is very similar to their “Augustine” hummingbird design (Do a Search here). I love the barely-discernible texture of these raised-ink papers. A unique printing process results in this effect.
