First time laying Sandstone

[sammy j]

Hi all

I'm just about to start a job doing floor and shower area of a bathroom with 600x300 Sandstone tiles (sandstone grigio which is apparently much less porous than normal sandstone). The one box of tiles I've seen seem to be calibrated so that shouldn't be a problem.

Putting it on to Marmox boards in the shower area and plyed out floor. Was gonna use BAL Flex on the walls and SPF on floor.

Anything I should know? Different adhesives? does it need sealing?

Cheers

be care ful with the balflex in the shower area it is fantastic adhesive but it discolours Silicon dont spread the final half inch into the corners this will help

Why not use spf on the walls as well.

 

[sammy j]

Not using the SPF on the walls cos they are so large, for the extra flexibility.

I would have used SPF as well, much less hastle.

 

[sammy j]

Well maybe I'll rethink and go for the less hassle then. Any advice on a sealer?

 

[wetdec]

are they honed or riven

 

[sammy j]

Not sure to be honest...only looked at the ends of the tiles in the box! Doh.

Its a hard one without knowing as cant really help with sealers etc

BAL SPF will be ok on that format of tile..........

 

[Spud]

you have to be careful when laying large format naturalon walls make sure your substrate can take the load

As he's using marmox boards gary then it will be fine.....they can hold about 45kg a sqr mtr........... ......but as you say you do have to be careful and all these issues should be considered.......
