What is White Set Plaster?

An internal wall system known as white set plaster has the following materials:

  • brick wall (also known as ‘substrate’)
  • cement render layer
  • lime plaster layer (also known as ‘white set’)
  • coat of sealer
  • two finished paint coats

The Master Plasterers answer, What is white set plaster?

White set plaster construction and finishing consist of three skilled trades—painting, plastering, and bricklaying. When done right, the finished product results in a durable, hard, and extremely smooth surface. For guaranteed results you should use an expert bricklayer, plasterer and painter.

Unless all painting, plastering, and bricklaying are done correctly, tradespeople will fail at plaster construction and finishing. This can lead to the project being delayed or the need for the project to be redone entirely.

Lime plaster layer usually provides a better finish to topcoat/basecoat. It is harder and the trowelling works to polish the plaster and give it a durable and dense finish.

Lime plaster layer is usually applied on cement render.

The Master Plasterers are experts at whit set plaster

Among solid plasterers, “Boral hard plaster” is the most used brand.

Before applying hard plaster, solid plasters must first dampen the render. This is effective at bonding the material and preventing the moisture of being sucked out rapidly. Applying white set has some difficulties such as timing and knowing how much to apply in a mix.

It tends to set very quickly and having it accumulated in the wall can end up in messy results.

    What would you suggest i do if a wall is at its scratch coat ( an old white set plaster wall)
    the plasterer removed the major chunks of plaster and the bricks had not yet been exposed. I’m looking for the finest and fastest way to deal with this delayed project. i’ve had to wait for so long to get these walls done right, and i will also call them back to add a smoother finish to the new plastered wall as its it’s left on the rougher texture.
    Is it possible to seal the left over scratch coat and start painting it. Will it take longer to expose the bricks and clean them well. or is it not overall, a good idea to leave a brick wall behind a shower and what i paint the bricks? i’m confuse because i got man options so it seems. i dont like how the plastere have done the job so far. these walls are old and only one wall had water issues under them. I’ve read that white set plaster and especially lime has good benefits for old walls , against mold and insects etc.
    Also i’ve noticed that in any wall of the house any screw hole would take off the lime plaster layer ts powdery and could be easily exposed to the cemet render. what is best way to patch the cracks and holes?

    what is best choice if you please.

    thank you
