Will this need undercoat or primer or something?

Post by Asian Boss »

I've stripped the wallpaper in my office so I can paint it.

One panel in the middle looks different to the others, like more of a top layer has come off during the wall paper removal.

Do you know if that means it will need undercoating or priming before I paint it?

I did the bottom stairs the other day and they all came out like the panels to each side in the image, and they painted straight to top coat fine.

Just looks like the lining paper came away with your old wall paper. But a roll of lining paper and stick a sheet back up before painting.

Just paper that one wall with some funky NYC traffic paper and paint the other walls. Feature walls are so hot right now.

I'd never heard of lining paper but I've Googled and that does sound like the thing to do.

It also sounds slightly hard to do for a numpty like me. I've never put up wall paper. Could I give it a light sand and then do an undercoat? Or primer and undercoat?

Light grey. Expcet I bought Farrow and Ball and they have 80 shades of light grey so it's called Mole Farts or something.

That's what it was - and what I'm trying to move away from.

Wallpappering is pretty easy. Fairly basic tools - brush, scissors, cutter, edge roller. A papering table makes it easier for cutting (and pasting glue if you're doing it that way)
You can get textured stuff which covers a multitude of sins (lumps and bumps). I've used some glassfibfre stuff in my auld house in some places where the walls are -really- bad. Painted as normal afterwards.

You have the option to hang lining paper horizontally to avoid the edges of the lining paper and the finished wallpaper coinciding. Generally the lining paper comes a lot broader than other wallpaper to help with this. Lining paper can be an awkward bastard to work with when loaded up with paste,but great for masking slight surface irregularities.

Thank you both.

I really don't want to use lining paper as I think I'll fuck it up.

I think I'll have a go at sanding then primer and undercoat. Or even just go straight to topcoat. There were some smaller areas like than on the stairs which I just did and two coats of topcoat did the job perfectly.

I thought so too - I'd been avoiding it because I literally haven't done any for 20 years. But pissing about with meticulous filling and sanding had begun to hack me right off.
Wallpapering with unpatterned paper is pretty straightforward, there's no pattern matching to be dealing with and yes it tends to come in wider rolls so coverage is quicker. I only intended to do a few walls but it was so easy I did the whole room in the end and I intend to do a few more now.

But yeah I can totally understand you might want to avoid it.

If you can find it the right width it should be pretty easily apart from buying all the crap you need to put up just one bit of paper. If you need to buy all the stuff or cut paper vertically then I think I'd just paint it and put up with the lines left on the wall.

Assuming this is a serious thread, you've pulled off the top layer of wallpaper, you need to get the rest off so it all looks like the bit with nothing on it. You'll need some water, a wide brush and a wallpaper scraper. Brush the water onto the remaining paper, then brush on some more, then some more, then use the scraper to remove the paper. If it's not coming off, brush on more water. You'll get the hang of it.

When it's all off, make sure the wall is smooth. Every blemish will show through on the painted surface. Once this is done, of out were me, I'd give it two or three coats of PVA (read the instructions on the can). Once all the prep is done then apply your chosen paint for a smooth, blemish free, long lasting look.

That's certainly an option that didn't cross my mind, I assumed it was lining paper used to cover up some rubbish plaster.

It's a serious thread.

My instinct is it's part of the panels, not part of the wallpaper.

I just took the wallpaper of the stairs and it was the same but without the bad panel. And it painted fine.

I bought a pot of Crown Primer / Undercoat. I'll give it a quick sand and then some of that.

I thought the Farrow & Ball paint was expensive but the Crown was £20 for a little 750ml pot. Bloody Crown goons had my pants right down there. I should get into the paint game rather than the turning-up-the-home-counties-accent-and-threatening-to-have-people-thrown-out-of-their-cottages line I'm currently engaged in.

Well it's worth making sure it's not part of the backing clinging on, the previous goon may have used mental strength glue on that bit for some reason. Hard to tell from your pic

Good paint is worth getting, fewer coats

Not that fecking one-coat stuff though. Hideous.

If you do use lining paper (we used 1000 weight in a couple of rooms), be aware that although, when dry, it's like cardboard, when soggy will conform to the surface below.

In other words, like paint, the better-finished the base surface, the better end result.
Even bland can be a type of character :wave:
