[evertonl36]

doing 14m of bathroom walls for a customer 3/4rs are skimmed the other 1/4 were the shower is going is not problem is the plumber has built a wooden frame 3 inches off the wall to accomadate a new shower which is being fitted on the frame has plasterboard against the frame the plumber is trying to tell me if i pva/prime the plasterboard i can tile straight onto it i think hes wrong but am not 100% now because he is adament you can any relpys would be helpful thanks.

hi dont use pva to prime///// you should waterproof or membrane the shower walls first is plasterboard normal or water resistant i would use acrilic as primer waterproof then tile hope that helps

[Fekin]

Plasterboard is perfect for tiling straight onto, but do not use PVA, give the plasterboard a good coating of acrylic primer and away you go, though tanking the walls is always a better idea if the customer is willing to stand the cost.

same as Fekin from me everton

same as ,but as belt and braces tank it out then,no come backs

with the others on this mate, primer NOT PVA...most of the good tubbed stuff contains acrylic primer but it's bound to be dusty,,tell the plasterer 'respectfully' things are done differently now.
Try to persuade the customer to have it tanked, worth it for peace of mind..imo

unskimmed plasterboard is one of the best substrates to tile on,
but i would recommend a tanking system in wet areas..
i know it an extra expence but, if the benifits are clearly explained to the customer most will take you up on you sensible offer!

[whitebeam]

Agree with all the above

[trevortine]

Me too, i tank nearly every job i do!

[dagger]

as a company we build in tanking into meterage rate, it makes no sence not to do it!
its quick, simple and lasts!!!!
you can paint the first coat on, tile an opposite wall then paint the second coat on...easy peesy..and no real labour cost, just the materials!
IMO.

and i am talking over baths and basins, not a full tanking job!

dagger - amortizing the tanking cost into the sq mtr cost in wet areas is so blinking obvious when you say it ... a no brainer idea! ... nice one dagger ... thx

[dagger]

its easy when someone tells you, almost all of my advice is second hand..
all i have learned over the years.....someone told/showed me!!!

thanks
Dagger.
