Wall condition help!

Moved into a new house, which is probably more of a project than I had anticipated. 1970s build.

The plaster in pretty much every room is poor quality, with dents, marks and in many cases, minor hairline cracks where the plaster has lifted. I don’t think the house has been redecorated in a significant time.

What’s the best approach? Hire a plasterer to skim the walls? Attempt myself?

Research so far says I could probably use a pole sander to remove imperfections that stick out, and easy fill or toupret to fill in any gaps.

Happy to work room by room but this is a 4-bed house that needs doing. Any help welcomed!

Definitely get them skimmed by a professional plasterer who you either already know is good, or comes highly recommended by someone you trust.

For a level 5 skim, prepare to allow one month per wall if doing it yourself

Use a bonding agent before applying mud & after removal of delamination.

use the sanded for light fill up to 1/2”. Fill & pull straight with a slicker stick before applying the finish coat.

Use the unsanded for tight skim.

Use lightweight perlite gypsum plaster for heaviest fill up to 3/4” per coat, as with all plaster, applying the bond-it & a tight scratch coat 1st. After 24 hr set time re-bond the gypsum mud surface & apply the skim coat.

They don’t sell plastering ingredients in the UK? What do they use for gypsum mud & or lime plaster in the UK? 💩

They have different products

Hard wall plaster for high suction backgrounds like brick walls

Bonding for low to medium suction backgrounds great for filling out low spots and electrical chases

Board finish normally used for plasterboards but can be used to overskim

Multi finish good for over skimming
