Garage floor advice...

[Olde Navy]

Back again...

Dear all,

Got a large garage floor c 40sqm+ which is going to be used for vehicles.
It'll be a new concrete floor and the customer has chosen a form of slate tile that needs to sealed (not seen them yet but think they are 300 x 300) so my questions are...

Once sub floor has fully dried out etc...

Should I require a sub floor e.g. durabase matting ?
Recommended adhesives - slow set flexible and certain brand from experiences?
Size of trowel - guessing I need 100% coverage so back buttering on a 6mm trowel ?

I'll leave one expansion joint for 'belt and braces' and use 3mm spacers
Also use a bevelled trim at the entrance

Any other suggestions gratefully accepted

Cheers in advance (as always)

for me, he's Chosen the wrong tile for that situation!

I don't think 6mm trowel + backbuttering would give you 100% you may need to go bigger

 

[On one]

Not sure of your backround.........but your thoughts on the need for a 6mm trowel on slate,on a garage floor raises a few questions.

 

[Flintstone]

I was going to comment on the 6mm but thought there were other concerns. 300x300 slate is usually riven slate, usually cheap, and usually incredibly fragile and uneven

sorry to have raised eyebrows but just hear me out ...,

Re. 6mm trowel.... I've always used 10mm or a 'tiger' trowel (so called be my independent supplier for its gauge!!!) . I saw on an earlier thread that there were concerns raised getting 100% coverage with 10mm which is clearly essential and assumed the 6mm back buttered would minimise air trap potential.

Re tiles.... as I explained I haven't seen them so maybe I've got the facts wrong but I have. Even told they are slate effect and need sealing - I guess the tile will be fit for purpose as the customer is fairly switched on

So hopefully I've clarified points and calmed concerns !!!!! Still open to advise so thanks again in advance

In what context?

 

[Olde Navy]

In what context!!!!! ?
i clearly assumed something incorrectly....smaller gauge less air potential... sounds silly now Can we now move on from the 6mm trowel comment !?

 

[Old Mod]

Can we now move on from the 6mm trowel comment !?

As you wish, I was just trying to assertain why concerns were raised over obtaining a full bed with a 10mm trowel, nothing more.
It was in no means a derogatory comment toward you.

Use your 6mm on the floor and the tile and you will probably get the coverage your after
