Plasterboard over brick and studwork

[DJM]

We had a leak which has required replacing the ceiling and plaster on a couple of walls. But one of the the walls is a mixture of stdwork and brick. Currently there is lathes on the studwork and plaster went across these (see pictures)

The question is is it best to leave as is and plaster over or remove the lathes and replace with plasterboard across the stud and brickwork?

First look at the levels.

Are the laths in plane with the brick? If yes, then add a layer of plasterboard to the laths, then double board over this whilst carrying on the plasterboard over onto the masonry. Use board adhesive dabs where the board hits the masonry. Ensure that the board always carries over the join between the masonry and the wood.

If the laths are already proud, do as above but without the thickening piece of plasterboard, i.e. apply dabs to the brick, fit board, screw one side and tap level with a straight edge the other.

As Noseall says above for best solution if wall is all in line.

But also in other cases where they don't run true.

You could actually dot and dab over the whole lot of it needs taking into line.

The laths will grab the adhesive, but for belt and braces put continuous dabs along the studs , and when fully set, you can screw into the studs with long drywalls screws.

Or you could put a sheet of board on the stud wall with screws , then dot and dab over the whole lot to make one nice wall

(Or even just rips of boards first over studs to accept dabs)

Many thanks for the replies.

Lathes are a mixture of in line and slightly proud.

As it meets a corner, ad that return is short up to the door frame in similar state brick, is it worht dot and dabbing board over that to form a neat corner for the spreader. Or am I over engineering it?

Do you mean a return (reveal) into the door?

If so consider if dabbing plasterboard on will be too thick and leave you proud of the frame or interfere with architrave.

(Best bet is ask the spread.)

This could be plastered with a tight coat of bonding or Hardwall. However, this will take time to set so may extend the time of the visit, compared to just skimming all boards .
