Preparing old plasterboard…

[Matt182]

Hi there,

I have decided to redecorate my bedroom, so I started of removing the border that was going around the room. This in effect removed some of the old paint, so I carried on pulling the old paint off, it came off just like wall paper but I did have to use a scraper in places.

My problem is that after removing all the old paint I am left with patches of emulation on the walls, I have been told because our plasterboard has not been treated I will have to remove all the old emulation and apply a sealant so that the new paint will key.

It has taken me well over 3h just to remove a small section, so is going to take weeks to remove it all. Is there another way around this problem?

Thanks,

Matt

The best way to treat your walls is to get an Indian take-away..

You are sooooooo cruel joe.


Matt, it looks like its plastered walls, I cant get the pic to look bigger , but from I can see, it looks like there is a plaster skim.
Do you mean its a skim over existing plasterboard?

Thanks for the better pics matt.

There is a few options you can do.....

Either carry on scraping it all off, and starting again with the paint, but first put on a miscoat, then your proper coats of paint.

Or, dont scrape any more paint off, but sand down the old paint, specially the edges and some will appear jagged.
You might notice a very slight indent between the old paint and the plaster, sometimes with sanding the old paint will blend into the plaster and feel flush.
If this doesnt happen, then you get some powder filler, and just lightly fill where the old paint is meeting the plaster, when dry, lightly sand, run your hand over it, till you think the two feel flush,(also fill any cracks, nicks, holes etc)
Then you get some diluted paint, and brush this on where you have filled, a couple of times.
Then you would apply a thinned down coat of paint,(miscoat) to seal all the bare plaster.
After its dry, you can apply your proper coats.

Last option, is to give the walls a good rub down, and fill where necessary, then line the whole room and paint.
