im new to plastering and i was taught at college when doing a re skim to put a thin coat of bonding on the old plaster before the new plaster. can you re skim without using bonding and jus skim straight on to old skim?
 
Hes talking about backing coat.

Some re-skims can benefit from it when they are a mare, but you need to double the price, which can loose you the job.

The majority of walls can just be skimmed
 
i dont mean to be rude but are you a plasterer and are you charging people for this work? no offence but its worrying for the trade if a so called plasterer hasnt heard of PVA. if you're still learning then fair enough :)
 
I did a ceilling yesterday that was only about 12 M2 it took over 3 f*ckin bags!!!

Dont'cha love Artex

Lets be honest steve there are other people on here charging asking stupid questions so thats not really relevent also he didnt say he hadnt heard of PVA.
 
i know flynny but i just notice is more when its a new member, i didnt mean to be rude. it just makes me angry when theres people out there who havent spent years learning and perfecting the trade to be outpriced of jobs by people who havent a clue, and no thats not a jibe at you KG. i just mean in general.

Im tellin Ya man this forums a breadin ground lol
 
used to put a light skim of bonding over rough bathroom or kitchen walls before skim up, if they was a bit bumpy because of tile adhesive etc..
but pva will be ok for most!
what collage you go too?? ::)
 
done a reskim were some kid had bonded a cracked perfectly flat stud wall. even put the staight edge over the sockets, i guess that's cheaper then buying a flush plug socket.

you sure the college didn't mean to use a bonding agent i.e pva? that was the problem on this job.

also qouted £80 to cove 12m in the kitchen. to expensive
 
i have just finished college and i have heard of PVA my question wasnt about PVA it was about whether you can just skim onto old skim or if you need to use a backing coat

And nelly answered your question
 
you need pva to skim onto old walls so if you'd heard of pva surely you'd know what it was used for?
 
i know now but just dont like people jumping to conclusions. has any body used wickes bonding agent before and if so is it like PVA?

to those asking about my college i went to the national construction academy and gained Diploma Nvq Level 2 Plastering Full Route
 
shove your warning up your arse! :-*

i'm just trying to understand his question. he knows what pva is and how and when to use it. but wants to know if he can get away without bonding a wall first. thats what pva is for isnt it?
 
i meant bonding as in bagged bonding coat by british gypsum. i was always taught to use a thin coat of bonding coat before skimming it or if you can just get away with using PVA and then skim.
 
If it is just a re skim then no bonding is required unless the walls are in a really bad state.

If the walls are un painted plaster then in both cases you will need to pva to control the suction.

If the walls are artex then you MAY need to flatten them off with bonding coat first.

It is up to you to access each and every job and to make the right decision on how to go about it correctly and in an efficient way so as to not over charge the customer and to leave a quality, clean job.
 
used wba on a concrete ceiling and worked a treat. i still wouldn't use as a replacement for pva yet as it works out a lot dearer. also gotta alow 2 hour drying time. so no good if you've got one surface to skim.

They should divide the plastering section into 2. 1 for newbie questions that may come across as silly, and one for time served plasterers. that way if you don't like reading obvious questions don't go on newbie section
 
maybe its not KG's fault, more the colleges for not teaching people these things. none the less its still worrying.

cheers richard. what about if the walls are painted?

Idealy you need a bonding agent for painted walls as they lack mechanical key and suction but most just PVA and scim when tacky
