I recently wrote about a 120m floor i'm doing and forgot to mention the staicases are being done aswell. We've had the strings templted and cut and each staircase is to be done with 2 strings each over 2m x 0.5m and 20mm thick limestone. Will a good cement based adhesive be strong enough to hold them up. The stairs are concrete and were cast in the position they are. They are sriously heavy and i don't know what weight traditional cement based adhesives can hold.

As long as you solid bed fix then no probs.....what nosing profiles are you going to use...schljuter do some very good ones..

The stringers i think he means which are the sides are the treads and risers being done ? :Pete

So are the stringers exposed..?...you might need to mechanical fix as well......

Pete isn't this your field of expertise.?...you do a lot of stairs..

Thanks guys, yes it is stringers, rises and treads. They are 2 big concrete staircases fixed to the back wall. There has been no mention of nosings so far. The supply said something about getting all the edges polished afterwards but i doubt this will be enough. Doesn't take much to chip these edges.

the treads and risers have to be of a constant size so take that into account if the stringers have been templated wouldn't mater to much as you are tiling treads & risers you have 20 mm to play with any good SPF should be ok but if you have to pack any depth of adhesive i would use nanolite also you would need to polish the edges first as it will be very hard to do it when fixed :Pete
