Bathroom Skimming Prep With Pva Before Tiling (wet Areas)

[Crumbs]

Hi, i am looking to re tile my bathroom and have got rid of all the tiles. Unfortunately some plaster damage has occured, i want to skim the damaged areas and use PVA between skim coats.

I know using PVA is a big mistake before the tiling in a wet area, but is it okay to use PVA before a skim coat when its in a wet area (shower above a bath)?? Does the same apply or is it safe?

Much appreciated 🙂

Yea i got that Andy, thanks bud

I did consider tanking it but its confusing what products to buy. This is only a shower above a bath setup, would good quality water proof adhesive and grout not suffice?

Money is on the tight, i did look at the Bal WP1 but seemed just a component of a kit, could the WP1 on its own be applied, would that offer good protection? Any other products you guys could recommend? Cheers

I do, I buy a fleece from B&Q for stopping plants getting sunburned (Truth) and it costs me about £3 for something like 6 m2. Cut strips for the corners and fold onto shower tray.

The correct advise here is to either do it correctly or don't do it at all. Gypsum skim is probably one of the worst substrates to tile on because of its limited weight tollorence, the fact that it causes chemical reactions with powdered adhesive and that its most certainly moisture sensitive. To answer your questions in this instance BAL APD is more suited to what your doing, SBR is more suited to sealing the back and edges of plywood etc. You say your budget is tight, but if you don't tank the walls your simply wasting your money long term anyway and it will end up costing you additional money to fix the damaged that will occur from not having tanked your walls. Spend the extra £50 or so and tank the walls, it'll be the best money you'll spend on this project. You also need to make sure that you've dealt with the joint between the bath and the tiles properly also. Here's some of the materials you should consider
Classi Seal ® Flexible Waterproof Upstand
Or if the bath is already fitted
All About Sealux Shower and Bath Seals for UK and Ireland
Then over lap either with this

Hope this helps 🙂

Thanks alot bud for the info, much appreciated. Your right and think i will tank the walls.
Yea skim is proberly not the best idea ive had but its my 1st tiling attempt and i've been told skimming it to make a flat surface will be easier for me. My tiles are around 11kg per m sq before addy so hopefully ill be ok on the weight, if i had time where i could pull the walls down id put in tile backer boards in but its a heavily used room and i dont want my head on a plate. 😱

I like the look of the sealux seal, where do you get yours from as i cannot find where i can actually buy it. I think thats where water got in before, the link between the bath and the tiles.
What addy / grout would you recommend Lee? prefer tubbed, Cheers

Online Crumbs, try this site
PVC Trade Shower Bath Trim Five Pack All UK

You can't use tubbed addy with tanking suystems, the adhesive will not cure, it would remain like it does in the tub.
Get yourself any c2 rated adhesive to be on the safe side from any reputable brand: Tilemaster setaflex and grout 3000 get good reviews on here or any BAL, Mapei powdered products etc.

Make sure you install the Sealux trims before you tank the wall though 😉

Sorry I have been away, coming back to finish this job now, thanks for the info bud, much appreciated.

I think I will go with this tanking product http://www.screwfix.com/p/mapei-shower-waterproofing-kit/78484
What do you think of this product? Can you tell me do I have to start tiling in a certain time frame once its applied?

As for the addy - I could do with one that doesn't require to be applied quickly as I am a novice to it all. I am struggling to know if bagged ones are suitable for waterproofing products or not, or are they all suitable if they are in a bag? Sorry bud for all the questions, much appreciated 🙄

No trouble at all Crumbs.
The Mapei tanking kit is perfect, just make sure you follow the instructions and use the primer etc.
The following adhesive is a good one to use, but as with all these products you'll get them cheaper in a tile outlet.
http://www.screwfix.com/p/mapei-keraflex-tile-adhesive-white-5kg/42841
This is a standard set adhesive and will give you a few hours to work with it, just mix up small batches and use this grout
http://www.screwfix.com/p/mapei-ultracolor-plus-grout-white-5kg/71681
Make sure you also follow the instructions on this grout and make it up in small batches
There's no time frame in which you have to tile on the tanking kit, so long as its cured it's ready to go when ever you are.
When you spread your walls also back butter the back of each tile with the flat side of the trowel
Remember once you have installed the Sealux trims, overlap the vertical edge of the trim that's against the wall with a length of the tanking tape running horizontally around the bath first, then put a vertical piece in the internal corner overlapping the horizontal piece of tape, this is pressed into your first coat of paste with a small roller or a trowel edge, once thats dried give the whole area a second coat of paste let it dry and tile it when you want.
Hope this helps 🙂
