time it takes for plaster skim to cure before tiling

[Little5]

Can anyone advise the required time it takes to cure a repaired wall before tiling.
I have had to repair a wall with bonding and a plaster skim before tiling in a shower cubicle. The bonding is about 15mm and the skim 2mm.
What timescale should i leave it?
Thanks

Whats the addy instructions say?

Varys, especially in his weather, have you got any heat in the room? You can usually see when plasters dry. (standing by to be shot down on that on though)

It looks dry on the surface but at 15mm bonding not necessarily under the surface. The addy i used the other day, it WAS tubbed said 4 weeks!

I always leave the window open as well as heat if its available, the moving air will help loads.

I been thinking about investing in a damp meter for the same reasons.

I aint knocking up addy for 10 by 8's!

approx 17 days. I would leave it three weeks to make sure its dry.

or you could use gypsum based addy......

2-4 weeks for me, depending on the time of year and depending whether its skim over plasterboard or skim over backing plaster...

1 day per mm of bonding so 15 days then your good

Thanks for all contributers.
The area i'm talking about is 1/2 square metre, with 10 x 8 inch tiles. its a repair rather than a full wall, should i still wait a month?????

Thistle Hardwall


use hardwall

hi little

just read the depth of which you are patching...

right, heres some advice you should take note of.......
if you are putting on 15mm of bonding/hardwall, then because its designed to be applied by the book at 11mm and you are putting on 15mm
i would do a scratch coat of around 8mm, allow it to pick up (firm up and change to a darker colour approx 1 to 1 and a half hours and then put the 2nd 7mm coat on, then leave it to set a bit longer than normal (around 4-5 hours and then skim..

if you put too much on in one hit, it will shrink and crack!! so build up the layers and control the drying/setting/suction time...

any probs just fire away with the questions

Very true but use hardwall rather than bonding dry alot quicker

i get your point but the background denotes whether to use bonding or hardwall not the drying time because over 2 weeks it really wont come into play..

hardwall for high suction backgrounds
bonding for low suction backgrounds......
both are around the same setting time. the substrate will determine what speeds up the suction which in turn speeds up the setting time so its important to get the right product for the right surface!!

if i were you little, just apply some water to the wall with a brush, if it soaks in immediately or to hear a sucking noise then go for the hardwall, if the water just runs down the wall and the wall is not very porous , then go for the bonding. that will solve it for you

Why not use some 9.5mm plasterboard with a fair bit of adhesive behind, that should speed the job along

is this true? when I tiled a kitchen wall with someone before he had the plasterer in and then tiled next day?
