Ahh.. how long do i need to wait...HELP

Hi

I find myself in some trouble... Stripped off a load of old tiles around the old shower area.. Then put a 5mm coat of Thistle bonding and then a skim coat to finish.

I'm using Ceramic tiles.. tiles are about 7mm thick


I've just spoken to Thistle technical support and they have said i need to wait 5 - 6 weeks to let the bonding an plaster dry before tiling...

1) HELP --Do i really have to wait 6 weeks before tanking with BAL WP1 and tiling?...

2) could i do it in a week?

3) If i did it in a week... what could go wrong??

please help!!

thanks

Stu

yes there tech dept are correct,what could go wrong is the tiles will de bond

Bonding Plaster is a nightmare, sorry but you will have to wait, if you dont your looking at a potential disaster.

Is this your house or a customers?

If time is important (sounds like it is), is it feasible to strip off all the plaster and fix backerboard?

Hi

Thanks to everyone who replied to my post.. really appreciate it.. even if it was not the news i wanted to hear!!

Ok..so two further questions if you would mind helping some more.

1) Is it the bonding that takes the time do dry... would i still have the same problem if i had just used thistle multi finish and not used the bonding?

2) the all important question.. what should i have done???

just to give you an idea.. the walls were tiled floor to ceiling on all 4 walls, they wanted compleatly new tiles so i stripped the old ones off, which left a very messy and uneven wall... I was hoping to refit the entire bathroom and retile all the walls within a total of 3 weeks.. ( i have 2 weeks left!)

Can you tell me what i should have done so i wouldn't have to wait so long for the walls to dry

P.S.. Its my Aunts bathroom.. as you can tell.. I'm not a Pro.. just reasonable at DIY

thanks again

Stu

Its the thickness thats the main issue. Could you strip it back and dot and dab plasterboard. You could tile that much quicker

over board the wet areas with tile backer board if it is a solid wall then glue and screw. over board the rest with the green plaster board. the drying time is now 0.

wediboard would be my recommendation....the whole building industry is geared towards thermal insulation now.

I'm confused. Wet gypsum based wall substrates tend to dry at a similar rate to gypsum flooring substrates i.e. 1mm per day up to 40mm deep. Slightly quicker if on a wall that offers 2 way drying. Strength development is related to drying.

If the bonding is 5mm and the finish skim is say 4mm why does he have to wait 5 to 6 weeks. I could understand it on new walls where you have to wait for the whole wall to dry. Personally I would have dot and dabbed Gtec aquaboard but won't argue with the wedi idea. Just not sure about the 5 to 6 weeks for maybe 9 or 10mm of plaster.

Be gentle everyone I'm a screedy type not a plastery type.

you have just read my mind alan

5mm for the bonding and 2mm for the finish....?? normal recommendations are for bonding that is applied between 9-11mm with a 2-3mm finish?? i know, that that the depths mentioned in this post would be ready to tile on in a week -10 days for sure but what do you do when the tech depts dictate the gurantee's

Hi Guys

thanks again to everyone who is giving me advice.. i really appreciate it.. I'm A decent DIY'er but clearly out of my depth on this one.. Just trying to do a good dead for my aunt who is in hospital having treatment for cancer.. she'll be out of hospital in 2 weeks, hence the time issue!

SKIM THICKNESS – HAVE I SCREWED UP AGAIN???!!!

SO... I know i've cause confusion with my bonding and skim thicknesses... Again.. what seamed sensible to me may have totally backfired!! having stripped the tiles and been left with a fairly uneven wall due to some of the old tile adhesive being left behind... I thought i'd just put a very thin coat of bonding on to the wall to cover over the old adhesive and make a flat surface... so.. i recon this coat of bonding is between 3mm-5mm thick.

Then.. having been told that i can't apply BAL WP1 to bonding, and that it must be applied to a finishing plaster skim... so I duly skimmed over the bonding.. Just 1 coat of skim.. aprox 2mm - 3mm thick at most.

I probably have a total thickness of between 5mm -8mm of bonding and skim.

HAVE I SCREWED UP AGAIN!! ?????

thanks again to everyone... I keep my fingers crossed that the answer to this post wont be bad news!

cheers guys
