Wall paint disaster

[bob w]

Hiya,
Am putting feelers out and finding threads on here about painting over wallpaper.
Would this be a good idea if the paper is boldy patterned, just to get better coverage?

One question. Why do you want to paint over the wallpaper? If it is boldly patterned wouldn't it be better to remove it first. Most paint outlets have a steam machine for about $30.00 per day and you can do an average room in about 2 hours and a large family type room in 3-4 hours. Unless you are wanting the pattern to show through the paint this would be the better option.
Cheers

hi all

phew! what a decently long thread this one has been

great reading though

was reading a few posts back about sealer/binder being used on plasterboard - just a quick note to watch out when using this as it can 'lift' the paper - not lift as it remove but just make it quite spikey (if that makes sense) which means a decent sand before next coats - it's awesome for new plaster set or powdery surfaces (providing you clean and sand as best you can)

back to the plasterboard if using dulux the Acrylic sealer undercoat (purple coloured tag) seems to be a better go (or the 1 step 3 in one)

also the nap length can affect what colour is left behind after painting

anyways a couple of quick throw in's

Took the risk (not my decision, but hubby's) to repaint the patchy ceiling in one room to see how it would come up.
Re-did in sealer undercoat and then in ceiling white.
The only result was a very sore neck and a lot of swearing!!!
Only a fraction difference improvement wise. Everyone that has a look at it, scratches their head and has no suggestions!
Had all the window treatments go in and unfortunately they only hid a little of the patchiness (deflecting the natural light).
Final decision 1: I'm not looking up as I walk around the house .
Final decision 2: If hubby wants it done again, he will be doing it himself.

Thanks to everyone for their help on this one!!

hi matrat sorry to here about the ceiling ...

was the ceiling painted before you replaired it ?

is the ceiling plaster glass or gyprock ?

And did you sand it down and use a oilbased sealer primer that you let dry ?

i have just replaired and repainted the ceilings in my place and was pleasently suprised by the outcome excepted for a few spots i did not sand enough .
i used solver plasterglass sealer and dulux once i tried the solver ceiling white but it is shocking the dulux once is worth the extra $$ ( IMO )
best of luck .

Hi Jags
Not to worry, we did the best we could with the $$ we had.
The ceiling was plasterboard and we used an oil based sealer/undercoat. No sanding was required as the ceiling itself was in good nick, we just wanted to freshen the look up as we were doing so much with the rest of the house.
As it turns out, our '1920's' evap air-con had a mini melt down and blew out a s**t load of water which ran to a lower point in the ceiling (being the study) and water damaged that part of the ceiling leaving a nice ripple effect.
Of course this had to happen after the ceiling had just been repainted
That happened following the 44 degree heat on Boxing Day when the evap just decided it didn't want to work anymore!
Anyway, another job has cropped up where we now need to replace about 40 broken roof tiles and ridgecapping before 'the rains get here'.
I keep mentioning the sale of the kidney. Check e-bay, as I am sure it will be there soon.
