plastering - advice needed!!

bernlyn

i need some advice. the plaster + bonding on the lounge wall has come away all the way back to the bricks. the wall area is about 2.4m x 5meters[i have no idea what it is in feet]. but the problem is, how can i ensure that the finished wall is level [even] in every direction.

a friend of mine had his wall done but there is bumps and lumps all over the place as the plasterer struggled to get it even.

any advice given will be much approved

If the plaster is coming away, then the wall was too dry, when it was applied.

If you are thinking of DIY, then you can either batten the wall out, or spot and dab it.

Plaster can also blow away from the wall when there is dampness on the wall.

A good plasterer will get it straight, but it is much easier if the wall is drylined.

The Direct bond method is one of the easiest and cheapest ways of doing this.

my two pence worth on this problem of yours,

choice 1

take of all the plaster and start again!
Choice 2
bond, plaster, and hope for the best
choice 3
plaster hole and then a thim layer over whole wall to level out
choice 4
dryline wall and loose 1 inch of space
choice 5
buy a very big picture and cover hole with that

it is not just a patch that has come away. the whole wall is back to brick now but how do i get the bonding on even. because if the bonding is not even/level then the plasater will be out aswell [wavy]

You could fit temp timber battens to the wall at 1mtr intervals use a leval and spacers if needed, then plaster bond every other one, then when set remove battens, the fill in the missing sections.

thanks

any ideas on how wide and thick the battons should be

20mmx45mm battens are good

Are you attempting this job yourself?

If so I strongly recommend you dryline instead, its much easier less stressful, cleaner and far easier to acheive the desired result especially for a 1st timer

i agree with the above the dryline method is the only option open to you if you are doing it yourself. you will not as a novice be able to float and set a wall your self and get it plumb, flat and smooth,it takes years of practice im affraid, speaking as someone who learnt.
you could do a small area yourself but not on this scale.
A good plasterer should get it straight just using there straight edges, without the need for batterns of any kind so it shouldnt have been bumpy in you freinds case.
