    Hi,

    Is there are a primer paint / something similar that will even out slight bumps on a wall caused by old paint that has chipped off?

    e.g. like below.

    Last time I sanded it down with an electric sander but still as you can see the second picture the surface is uneven at an angle. Would like to try and avoid plastering as it's a large area and my plastering skills aren't great!

    1400 grade lining paper should hide the imperfections.

    If you go for 1000 grade then may need to use filler such as Easifill first.

    Tips for hanging lining paper- use a roller to apply the paste. Use something like this as a smoothing tool.

    https://www.amazon.co.uk/Coral-69500-Paperwiz-Wallpaper-Paper-Hanging/dp/B00O60CORW

    Butt the joins and use the tool to wipe away air bubbles. Wipe the joins clean with an absorbent cloth, use something more like a bar towel than a J-Cloth.

    Buy a decent snap off blade to cut the ends and use a thin, long filler knife as a guide to run the knife along.

    Olfa make the best blades. Get the black blades they are much sharper than the silver ones.

    https://www.amazon.co.uk/Olfa-XA-1-...eywords=olfa+9mm&qid=1581784063&s=diy&sr=1-10

    and the spare blades

    https://www.amazon.co.uk/Olfa-XA-1-...eywords=olfa+9mm&qid=1581784063&s=diy&sr=1-10

    At the skirting, corner joins and ceiling. push the paper into the join with your wide filling knife and then run the run the Olfa knife parallel along it to get a clean cut. If the paper rips then the blade is too blunt (snap a section off) or you haven't applied enough pressure on the wide filling knife. If the walls joints aren't very straight, use a smaller filling knife.

    Here is an example of a wide filling knife

    For the sake of convenience I have linked to amazon. Your local decorators' merchant might be cheaper.

    Thanks!

    I didn't think about lining paper.

    There are several door frames to go around and corners. Having watched a few YouTube videos I'm a bit worried my seams/edges aren't going to be great.

    I might contact a few decorators and see how much they'd charge to line them, I'm sure it's going to be a lot cheaper than plastering, I hope!

    Internal corners, you just butt the paper into the corner and cut away the excess, caulking once dry.

    External corners can be a tad trickier, especially if things aren't straight or out of plumb. I normally run about 5cm around the corner and then lay another sheet over it and use a long straight filler knife to cut through both to create a new butt join. I then fold back the second sheet and remove the wanted cut through excess from the first sheet. Apply a bit more paste and but the sheet upto the first sheet. If the return on the first sheet tries to crease because the wall isn't straight, you may need to cut a subtle V where the crease wants to form.

    I try to ensure that all of my joins butt up tightly but sometimes you will end up with minor gaps, there are limits to how far you can stretch lining paper. Those gaps I fill with Toupret RedLite and sand with 180 grit paper.

    Timewise, assuming that the room is empty, a decorator could do the "average" square room in a day. The more doors, windows frames, sockets and radiators, the longer it will take. Some will drain down radiators to remove them, others will tuck the paper behind them. Really bad decorators will cut around power sockets, respectable ones will unscrew them first.

    Over the last few years the quality of work that I have seen has dropped substantially. In part I think it might be the result of those online sites who claim to be able to find you quality tradesmen. Whilst there are some good tradesmen on those sites there are a lot of rubbish ones. My advice would always be to get quotes from decorators that have been recommended by close friends.
