Advice on plastering

[mushypeas]

I have got the plasterboards up in my bathroom and was wondering if i could get some advice on how to plaster, i have never done it before (as some of you will already know from my previous posts ) and i was wandering if you knowledgeable people could point me in the right direction. here are my questions !!

1. mixing plaster, what am i looking for in the consistency, length of time to mix for.

2. what is the best tecneque for getting it on the wall, where to start, which way to go EG:- left to right top to bottom ect.

3. how long do i leave it before i put a second coat on

4. anything else you think might help me.

5. how do i go about doing the corners and the ceiling joins
Thanks in advance

no disrespect Mush, but i think you will make a bit of a hash of this based on your questions but hats off to you for trying i suppose:

Q1. mixing plaster, what am i looking for in the consistency, length of time to mix for.

A1. no lumps in it, i like my finish to be quite wet, if i take some out of the mixing bucket with my gauging trowel and tun it 90 degrees, the muck only JUSTslides off into the bucket.

Q2. what is the best tecneque for getting it on the wall, where to start, which way to go EG:- left to right top to bottom ect.

A2: left to right (if you're right handed) bottom to top

Q3. how long do i leave it before i put a second coat on

A3: no hard and fast rule really but when it's firm and feels sweaty to touch

Q4. anything else you think might help me.

A4: get a pro in to do it or practice on some spare board before attempting it

Q5. how do i go about doing the corners and the ceiling joins

A5: recommend you take it slowly and do 1 thing at a time and pay attention to your corners, brushing them in after each coat.

best of luck, and in return...post us some pics

A well considered reply throughout TM1.

Even coming from an amateur with a bit of exp now.... M/peas - I don't think you're yet aware what you're letting yourself in for, from the questions posted.
Full marks for having a go and I couldn't agree strongly enough about having a go on a bit of plasterboard first. You can at least practice your mix and get some basics with a finishing trowel.

TM1 - on the edges, do you clear snots that stick to the adjacent wall at the edge? I know the first coat is meant to go on quick, and I find that sometimes if a bit has stuck to the adjacent wall it can dry fast and you inadvertently drag it across on coat #2. (sorry to hijack slightly m/peas - but it will help you too )

Mushypeas.....this made me laugh as I had a go myself,took loads of advice,took the day off work,bought all the gear but had no idea..... although I am ok at most things this is one where I am not......got a plasterer in ...little guy flat cap and smoked like a test monkey while drinking lots of tea. This guy made it look so easy and quick and the job was second to none.....get a pro in as its going to be there a long time

How about ,"
Question....
I am a female, and single with my own house and lots of money and would love to learn plastering, would you like to come around to my house in the country and teach me"?

Answer ...YES!!!!!!

A2: left to right (if you're right handed) bottom to top

Bottom to top
If I'd laid a trowel full on the bottom of a wall before I'd laid the top in I'd of got my lug slapped so hard I'd of been off my feet.

 

[roy c]

Always top to bottom ...

R/hander Left corner..

L/hander Right corner...


Probably a Typo error by TM

I think TM was refering to the upwards sweeping motion you use to apply the plaster.

You will need very long arms to do a full sweep from bottom to top so do it in two halves.

Do the top first then drop down and do the bottom.

How would you explain to someone where to start plastering from islandview?

 

[islandview]

Ha Ha you have got me there!!

Its better to see it rather than explain it.

I would say if you were to skim a wall then do it in two halves, top half, bottom half.

To do the top half apply form middle to top.

To do the bottom half apply from bottom to middle.

I won’t go into any more detail about how to plaster as the others have that well covered; all I would say is don’t expect too much from your 1st attempts, you may do better to get someone in to avoid disappointment.

Here are some other factors you should consider for your bathroom project;

• It’s not necessary to skim plasterboard where your tiling. Unplastered boards will support a tile weight of 32 kg/sqm, plastered boards only around 20 kg/sqm (including adhesive & grout). This could be an important factor depending on the size/weight of the tiles you propose to use.

• Use Moisture Resistant PB in a bathroom not ordinary wall board.

• If you use PB in wet areas, it should be tanked (even MR) or better still, use a waterproof time backer board in those areas.

• MR boards require priming before plastering.

• Never use standard PVA to seal/prime areas that are being tiled onto, particularly in wet areas.

• Use only quality trade flexible adhesive & grout, not cheap DIY shed stuff.

• Heavy tiles will require a cement powder adhesive not tub mix; Gypsum plaster must be sealed when using cement based adhesive.

yes yes yes, Answer 2 wasn't too clear now was it

in answer to your snots newbie, i will wet the adjacent edge so that the plaster doesn't dry into lumps so badly, then brush the edges in as soon as i've laid it on to get rid of any nasties that may be lurking

 

[mushypeas]

Right bottled out of plastering it because the tiles r too heavy . Which tanking kit would you recomend BAL WP1 or the dunlop? does this affect the weight of tile? Thanks again for being patiente with a numpty like me .

 

[roy c]

Last tanking kit I used on a "wet room" was a Bal product, but I tend to and have used their products for years (Adhesives, different ranges for different circumstances, and their grout as well. You cant go wrong with their products in my opinion And I dont think any of the lads on here would class you as a "numpty" MP...
