Help!!!! Tiles falling off wall!

[Lily Swizzle]

Hahaaaaaaa!!!!!! Just tried the heat gun - it's the way to go methinks!! Here's a pic of where I'm up to so far. Taking a break now - till tomorrow. See you then peeps. x

Treated myself to a new scraper today - one with a tungsten carbide blade (thanks for the tip off Alan!). It's great!! Have nearly got all the paint off the wall by the length of the bath! Have been using a mixture of new scraper and heat gun.... marvellous!! Thanks guys, will keep you posted on further developments. x

Just found a big hairy bit in the wall!! Had visions of a human head hidden underneath - but I'm sure it's nothing that sinister!! Have bought some one coat plaster to fill up the other big holes where the plaster has disintegrated...... Never plastered before so I hope I can master it.....

Most probs horse hair Lily, how old is the house? horse hair was used to bind old lime sand mortar.

Hi Phil. The house was built in 1907 so could probably be horse hair as you say. Have nearly got the paint off the walls but in some places underneath where the paint was removed appears to be a horrible brown coating of something (doesn't look like paint to me). (See pic). Do you think I should try and get this off as well? Or will I be ok painting it with the Mapei Plaster Primer I've got when I prime the rest of the wall.... (once I've plastered the big holes....). Thanks.

Lily When you re tile try not to put the adhesive on so thick. To thick = tiles fall off. Tub adhesive is a good product if used correctly, even if its fix and grout made by Unibond.

I was trying to work out some comments from earlier "pros dont use tub adhesive" "that type is rubbish"

There must be 350 topps tiles, say 100 tile giants 30 or so tile depots, 500 tile independents and say another 100 distributor showrooms 300 BQ 150 Wickes etc (i could name many more) in the UK.

If each one only sold 30 tubs a week (most sell that a day) thats 46,000 tubs a week. 46,000 tubs is a minimum per week thats 800 pallets.

Is tub adhesive only being used by DIY people fixing tiles? I doubt it very much.

Im not saying tub adhesive is better than powder adhesive but if used correctly it will stick tiles to walls for many years.

Food for thought

The hair could be the old superstition of burying a live cat in the wall when house was being built Lily :yikes:

I think we mean proper tilers use powdered adhesive.

This in turn speeds up the tiling process , as tubbed adhesive takes a lot longer to cure/dry with it being a dispersion adhesive and also bagged adhesive is not affected by moisture ingress if that occurs.

Tubbed adhesive is fine yes, but has its limits and tile size will determine its use, 300x300 being the max size.

And most tiles are larger than that now and staff at a majority of shops need to be educated in what should and should not be used.

I dare bet an awful lot of tubbed gear is sold for incorrect use.

Haha CJ..... live cat, human head or horsehair, it's all been reburied behind some new plaster now so whatever it is it won't escape...or give me nightmares.... Quite enjoyed the plastering malarkey - for a first timer - made a bit too much though but at least I'm learning as I go along so will make a bit less next time.

And I've already bought my next lot of tile adhesive - A bagged one by Mapei - Single Part Super Flexible......

Here's where I'm up to so far: 3 pics before plastering:



1 piccie after plastering:



Just had a thought - do you think all that horrible brown stuff is old PVA from years ago? If so, will it still be active and will I need to remove it before I prime the walls with the Mapei primer? (Been reading your PVA/Primer threads and know to steer clear of PVA al all costs!!...) Thanks

Not too sure what it is Lily. You will be able to tell if it's pva by wetting it and feeling it with your finger, if it'spva it will feel slimey.
If not I'm sure it will be fine with a coat of acrylic primer (make sure you dilute it down correctly)
