I used Fibolite blocks on inner skin of my kitchen extension. 150mm cavity filled with Knauf mineral wool batts, outer skin is brick.

Would like to get internal block skin wet plastered rather than dot and dab.

Is wet plaster OK with such block types?

Will need to get cavity closure fitted for the door and window reveals.

Any ideas on how to tackle wet plaster on cavity closures?

Thanks

It’ll likely be prone to cracking. I’d dot & dab it tbh, same then with the reveals, but I’d use insulated boards or Marmox insulated backer boards there, as you may not have much thickness available for insulated PB.
