Tile Over Existing Tiles

[Paul Finn]

can't say I've ever been a big fan of tiling over existing tiles but if the customer needed a small downstairs toilet floor or something similar and were on a budget, then as long as current tiles we're firmly fixed and sound with no underling issues, then I've always agreed to do it using a flexible cement based adhesive or similar depending wether concrete or ply base, and tbh I've never had a come back although to be fair it's very few I've tiled this way. I'm a firm believer in "out with the old, inn with the new"

Here's where it gets tricky! Mapei themselves have been out, surveyed a job and told one of my customers that it would be fine to tile over existing using there adhesive.

I'm no technical adhesive expert or mathmatician, but I'm very aware that adhesive companies like to swerve from a guarantee on there adhesives.

So if Mapei have said it's ok using there products and I'm agreeing to do job to that spec, then where do I stand "if" any tiles ever pop up Due to no fault in installation?

Bearing in mind this is a 400m floor.

Do I need a Mapei rep to overlook the job for me?

As always, any help appreciated.

Thanks

Cheers for info Pete.

Guess I'll just have to spend a day or two properly preparing.

I'm glad someone else has done a few showrooms to that spec with no problems.

Do you have help?

A few lads have requested experience on the forum lately. Perhaps worth getting some free help in to get it down quick.

Yes Dan,
Myself and another tiler, both experienced, and 2 tilers labourers.

Team of 4, have it tiled in a jiffy M8.

Just more conserned about covering my own back. Maby I'll draft a contract outlining potential issues and if there still happy with spec then sign your life away

I wouldn't worry about it. One of the best surfaces to tile to are tiles. Just as long as they're fixed well themselves of course.

Whack a few up. It'll soon give you confidence. Perhaps take snaps or videos of the process and save them long term as part of your guarantee or whatever.

 

[Paul Finn]

yeah, I'll do that Dan.

Cheers

Has it always been a car showroom that floor? I'd have a strong suspicion that if it has, and there's no sign of repairs, then it has been fixed using a similar spec to what you've been given.

 

[Paul Finn]

Yep, it's luckily at the end of my road and since it's been built its always been a car showroom. Current floor been down for 4 yrs, no initial sign of cracks/loose tiles etc

Certainly looks like it!!!

 

[Paul Finn]

no idea what they are/were, they were in a corner ready to be skipped and we needed to tile the far corner so moved onto tiled area until skip came.

They are the devils invention, that's what paramount board is!!!!

Tiling looks tidy @Paul Finn

Looks smart.

Get them in a new album on their own, name the album "Car Showroom Tiling in Warrington". Post as many pictures as you have. And give the album a good description also saying "Car Showroom Tiler / Tiling in Warrington" and stick your contact details in the description too. - You might get a bit of business from that album then if somebody is looking for a tiler that does that around there.
