DIY question- Painting

[Jeremymichael]

Hi everyone, I'm doing up my pad so that if I score my place looks good.

I've noticed that on my plasterboard walls leading to my front door the paint is flaky and blistered. I was wondering what the best way of dealing with this, should I just scrape it off and then sand?. I don't want to do the whole wall but just the bit near my front door, but after doing this I will be left with an uneven surface of bare plasterboard (where I have scraped the paint off) and the rest of the painted wall. Any ideas?, of should I just paint over the bare wall aswell as the rest of the wall, and just sand the joint after it has dried to leave an even surface?.

Many thanks and sorry for the boring question!

Get a scraper, it looks like a handle with a wide metal plate.. Scrape all paint that is flaking.. Use outdoor plaster/filler to fill and even surfaces that you have scraped.. Then sand it to make it look nice and even.. Then paint the whole wall.. Be sure to use outdoor tough weather everything.

It's flaking for two reasons, either a lot of sun, or a lot of moisture.. Depending on which one, try to get materials that resist either sun or moisture..

If it's sun, plant something there..a

Is it inside, not out? Gypsum plasterboard is called 'drywall' or 'sheet rock' in the U.S., and it is only used indoors. I have worked with it a lot. As the other poster said, you scrape, sand, fill, re-sand, wipe the dust off, and paint. They make special sanding pads that make it easier to sand level.

thanks very much for your help. I scraped of the peeling pain near my front door, it's an interior wall, sanded and repainted. Unfortunately I've notices it has blistered a bit and will eventually start peeling again. Should I have put a primer on first?, then added the imulsion?. I have plaster walls, not much I can do about a bit of ventilation coming through my letter box etc?

ok, now I know what you mean by plaster. Older houses in the US have that. Your walls are made of thin boards nailed horizontally across the studs and then coated with a plaster that dries like concrete. I have not worked with the stuff much, except to smash walls like these down with a sledge hammer, which is a lot of fun, btw.

Here is the primer I use for Gypsum sheet rock. It should work on plaster:

You might ask the guys at your local hardware store what they suggest.

Before you go ballistic sanding on that, know that there may be lead/asbestos underneath the top layers of paint. take precautions! I would lightly scrape the major stuff, then maybe hit it with Kilz. if it is a smooth wall, float the area with drywall mud, let it dry, sand, and repeat, and paint. I dont know what U.K. walls are like, though. It sounds like maybe the old paint was oil, and not sanded before latex was put on top.
