Hi, looking for some support with first travertine bathroom. Thank you

[Beags]

Hi everyone,

I'm a couple of weeks away from beginning my first tiling job in my bathroom. I've been searching this site for several days now and have a few ideas but there's just so much to absorb and I would be really grateful for some clarity.

I'd like to be able to give something back but at the moment I'm all questions - one day I hope!

My plan for my 10ft by 7ft victorian terrace bathroom is as follows....

• full pedestal basin, close coupled toilet, bath with shower over and valves etc built behind a pertition wall, victorian style radiator & one window to tile around.
• 12mm 400mm x 400mm medium unfilled travertine floor tiles
• 12mm 400mm x 600mm medium unfilled travetine wall tiles
• Currently cermaic tiles on skimmed plasterboard which I plan to remove and replace with new plasterboard. I don't think there is a stud wall behind the plasterboard but just the old brickwork, I suspect it is bonded rather than screwed and plugged
• I believe the floor is currently ply wood which I may replace with the same to keep cost to a miniumum

I would appreciate help from anyone with a few questions which are:

1. Can I replace the plasterboard and using a dot & dab technique rather than plugging and screwing into the old brickwork?
2. What adhesive should I use for a) the floor and b) the walls? Can I use the same stuff? Waterproof for all the room?
3. Do I need to prime the plaster board? If so, with what?
4. Should I seal before laying the tiles as well as after?
5. What's a good colour grout for medium coloured travertine and leading from that question, what grout should I use?
6. When grouting, can I spread the grout over the entire tile as you would with ceramic or do I need to be more precise when filling the gaps on travertine?
7. What's a good tile spacer size for these size tiles?
8. Best notch size for spreading adhesive on walls and floor?
9. How big a gap should I leave between where the bottom wall tile meets the floor tile... and what about internal corners?
10. I'm going to get a Rubi 180 for this job. What do I need for drilling though the tiles for radiator pipes and other fixtures and fittings such as toilet roll holder and towel rail?
11. Do I need to use Silicon anywhere? If so, what would you recommend?
12. Is anyone against using Lithofin sealants? If not, what specific product should I use to keep the stone looking as natural as possible?
13. Presumably the process is... remove existing tiles and suite, temporary fit new sanitaryware, sort plumbing, remove new sanitaryware, tile walls (apart from bottom tile), tile floor, tile bottom wall tile, final for on new sanitaryware? Does anyone disagree?

I think that's it for now. Sorry to be so prescriptive but it helps me to try lay my thoughts out on paper (head's all over the shop at the minute).

Thank you very much
Chris

Captain Slow, Opticolour is a resin based grout that Mapei claim is waterproof.

If someone here knows differently please let us know.

Now, I don't know anything about the Opticolour product so I cannot advise whether it is an epoxy grout or not.
As you are a novice tiler I would strongly advise you to stay away from epoxy grouts as they are not the easiest to work with, and on un-sealed travertine you will be inviting trouble.

As I said Aqua.......:lol:

Either way, I would advise a novice to avoid epoxy and resin based grouts 'cos they are much more awkward to work with.

Captain Slow have you seen the Mapei video demo I posted on another thread. It's a piece of cake. No boiling water.

Hi Aqua,

Thanks for the vid etc..

I have just a couple of queries for you.....

You suggested to the OP that Opticolour could be used instead of tanking, and yet the third bullet point in the "Technical Notes" section of the flyer states "Use a waterproofing membrane when required". I could only find a statement from Mapei that says stain resistant, not waterproof.

Opticolour does not appear on the Mapei UK website. Any idea who stocks it in the UK, I wouldn't mind getting a quote from a UK company to see how it compares with other grouts.

TIA.

Captain Slow, I will double check with Mapei and post results.

Here, William has tested this resin based grout. However, Mapei as you rightly state suggest a membrane. ?? Worth me checking as I'm also interested in this product.

Hi,

Assuming I go with plasterboard on the walls and plywood on the floor :mad2: , would I really get away with just using primer G on them both or do I need to consider these ADP and SBR products I've heard a little about?

I may go for a hardibacker bath panel as this is probably the area at most risk. If I do this do I need to tape the joints or prime with something different?

Also, with a plywood floor would I need Primer G on both sides and what about hardibacker on the bath panel?

 

[aqua blue]

I would use primer G on the plasterboard but would not trust tiling on ply personally.
I would overboard the floor. The bath panel is less important than the floor.

Captain Slow, I have found that Mapei don't distribute Opticolour to the UK, so it's back to Kerapoxy if you like to tackle water at source.

Hi Beags, thats sounds easy when you say it fast! how much time are you giving yourself for this project.
