Travertine

[jimbo]

Hi I am tiling a bathroom with 300/600 travertine tiles. I intend to use hardiebackerboard on two of the walls and was wondering whether Iwill be able to tile straight onto the other walls walls that have been plasterboarded and skimmed some time ago. Also will i be able to tile the floors with travertine onto 3/4 inch marine ply/

[brian c]

the backerboards will be fine,are you going to tank the walls?What Travertine is it..ie is it honed and filled etc?need to watch the weight ratios of the tiles on the skimmed walls.Iwould back butter the tiles and serate the floor then fix the tiles.The tiles will probably require sealing.


welcome to the forums m8.

in addition i would use a white flexible adhesive(cement based )on the floors and a white cement based adhesive for the walls.

Cheers for the info
The tiles are honed and i intend to tank the walls with a mapei kit the customer has supplied
I have used one of these kits before and it seemed ok
How many times do you think i need to seal the tiles?

[doug boardley]

as with Brian

[brian c]

twice...once before grouting and once after grouting.

[grumpygrouter]

You def be careful with the trav on the skimmed walls. Check your tile weights first before proceeding.

[whitebeam]

I do it after grouting but work clean

[jimbo]

Will i be able to tile over the tanking paste i intend to put on the floor? Will they adhere ok?

[brian c]

as long as its not PVA.

[mozzy]

you should be ok to tile onto the walls with hardibacker as it hold 45kg per m2 but you may have a problem with the plasterboard that has been skimmed as the weight issue is about 20kg per m2. also prime your plywood with acrylic prima n use a flexi sticky n grout

It's a bit picky, so sorry Bri, but I would "back skim" (i.e. a flat very thin skim of adhesive designed to fill any voids) and not "back butter" (i.e. a coating of ribbed adhesive on the back of the tile) so as to keep adhesive weight to an absolute minimum.

Seriously though, watch your weight limits on the skimmed plasterboard.

Oh and BTW, welcome to the forums

[inspiredandy]

defo with the others on this one. The skimmed walls will be a no no.

i did a lt of travertine on skimmed walls and all are still fine

no worries Daz but read it again..its on the floor ...

They may be fine, but as weight limits are set for a reason, it would be irresponsible of us on the forums to recommend to the general public that they are exceeded. Did you actually weigh your tiles before you fixed them and did they fall within the accepted weight limit criteria?

[sg tiling]

well... i think you are right Grumpy ..it should not be recommended and i do not do it either .I laid it on a site where everything was prepared before I started tiling. ( even worse -new plasterboards they skimmed with plaster??!!) I noticed it to them as that is wrong , but people on site do not care too much. Of course I primed the walls and used good adhisive ( mapei white keraquick) and as i know for now is ok.
HOPEFULLY FOR AGES

[jimbo]

Thanks everybody for your responses. I have used Bal 2 Part flexible before and was wondering whether Keraquick flexible was comparable in price. Who stocks this?

[brian c]

ctd,tile giant

[jimbo]

Dont think there are any branches near manchester

[sg tiling]

white keraquick £19 - in my local shop in seaford near brighton .not too far?

[jimbo]

Bet its not raining neither
