Rendering a wall

[Terry-La-Tiler]

Hi Guys,

I'm hoping that a few of you might be able to help me out and give me some advice on the follwing. I'm hoping too that a few of you might have lots of patience because I suspect that this first question will most certainly not be the last and you can probably expect many more from me in the weeks and months to follow.

I'm attempting to tile my first bathroom at a friends and have come up against a number of problems before I've even thought about sticking tiles to the wall.

Firstly, I have begun to bash the existing tiles off the wall with a hammer and bolster and even though I expected some plaster to come off with them. I really didn't expect all of it to come off with them! :whatchutalkingabout
The walls now consist of a sandy cement constitution and there is a very small area (bout as big as a tennis ball) that has come off too and is down to the brickwork behind it.

On a course recently, we were shown how to render a wall and 'make good' using a dark grey / black plaster type mixture.
Can anyone here tell me what this stuff might be called, where I might buy it, and whether I would be likely to be able to make good these walls prior to tiling.
I really hope that I'm not going to have to get a plasterer in or consider dry lining. I got enough on me plate as it is!

Secondly, I also intend to tile the floor, as the floor is made up of floorboards and I realise that I will need to board it with ply and use a flexible adhesive and grout. I'm wondering though whether any of you might be able to tell me the name of the boarding that is supposed to be much thinner and stronger than ply, and where I might be able to buy it?

Thanks very much.

Terry.

floor -hardi backer boards come in various thickness'

walls -fill them with rapidset adhesive once you have got rid of ALL loose pieces of plaster and primed wall with acrylic primer.

you could also dot and dab new plasterboard on to wall concerned and this will give you a new clean surface to tile....

it sounds as though walls were originally dubbed out with 2 coats of sand and cement render, sounds as though top coat has perished and I wouldn't be suprised if first coat has as well. Hate to sound pessimistic but if this is the case it all needs to come off. I appreciate it's at a friends but it really needs sorting bottom up so to speak.Being a time served plasterer it would be a walk in the park for me to re render but I'd suggest you dot and dabbed plasterboard onto brickwork. The grey/black plaster you queried is probably bonding plaster.
good luck,
doug

I take it you mean the finish came off leaving sand and cement backing, Is it old and soft or quite strong, If tapped does it sound hollow or firm...?

a couple of months ago i did a bathroom and one wall (outside wall)was really bad and had to have all old render and crap off and rerendered,got a builder friend in to redo it payed him to do the job,then a week or so after went in to start job then found out that customer had bought a semi pedistal basin which wasn`t a real problem just had to chase pipes in to wall,low and behold shed loads of the render came off, so as i was on the job was a bit up the s**t creek with out a paddle to say the least,so rang the tech guys at BAL and they suggested there quick set render so as no BAL stockist near me has heard of it let alone ever stocked it so ordered it online got it delived to my house (which came AM the next day) never rendered before so was new to me but did as per instructions on bag,builder still a friend,but will never ever get any work from me again,loved the stuff and the ease of use that i`ll always do my own rendering from now on

They would do......:lol:..fortune.....better just to use a quick setting cement and some sand from builders merchants.......much much cheaper and dose the same job..

Can't say I agree with you there Dave - like BDS I had limited experience of rendering but like you, I used to use a cement & sand but can confirm that the BAL Quick Set render is so much easier to work with. Have you tried it?
