Hello, I'm having some work done in my Victorian house. The walls are mostly the original lath and plaster. Although I've employed a largish company I have some questions about the plaster work being done. Most of the original Lath and plaster is sound but it has some old repair and damage. The plasterers are using 3 materials, bonding compound, Joint filler (and tape) and finishing off with Arrow-lite Joint cement. They are then sanding the Joint Cement back to a smooth finish. My question is, is this normal sound practice?
You don't mention boards, but I assume they are dry lining the holes, filling the gaps with filler & sort of skimming it with the Arrow?
Not exactly sympathetic to a Victorian house, infact dog rough if you want my honest opinion.
If it were my house I would be expecting all patches on external walls to be filled with Thistle Hardwall, and all stud/ceiling to be boarded & plastered out flush with the existing using Thistle Bonding Coat. I would then insist the whole wall was treated with PVA, SBR or Thistle Bond-it, and re-skimmed with Multi Finish.
The taping/filling techniques you are experiencing are more at home in shop fitting or office blocks.
But as said before, a picture would say a thousand words!
