If you’ve ever had plaster fail to stick, crack, or peel away, chances are the surface wasn’t properly prepared. Whether you're skimming over painted walls, bonding to concrete, or tackling plasterboard, surface preparation is the key to a flawless finish and avoiding costly callbacks.

The Common Challenges Plasterers Face

 

Across the UK, plasterers are under pressure to deliver perfect results, fast. But tricky substrates and tight timelines can make that tough.

Here’s what you’re up against:

  • Low-suction surfaces like paint, concrete, or plasterboard that resist bonding
  • Time constraints on busy sites with multiple trades working at once
  • Unreliable bonding agents like PVA, especially in cold or damp conditions
  • High client expectations - flawless finishes, no excuses

Sound familiar? You’re not alone. Trade forums are full of stories where plaster has failed to adhere, often due to poor prep or the wrong bonding agent.
