fella rung me sunday ,wants to price a job, 21m2 of travertine

he says the floor is half concrete ,the other half is concrete but stepped down,a chippy has made the level marry up with ply ect...

so regarding a movment joint, if he dosent want a metal or plastic strip schutler type ,down the centre of the room,could i use coloured mastic?

or am i talking from my unmentionable

any other ideas boys?

cheers steve

it definately needs an expansion joint where the 2 different floors join. you can use coloured mastic as an expansion option but a nice trim will look more appealing imo,

decoupling membrane might be another option aswell as the cold joint.

hi brian

when you say another option, do your mean the decoupling membrane instead of the expansion joint where the 2 different floors join?
