Help prepping treads and risers on external steps

[JLM Tiling]

Yeah that sounds like an identical situation! How did you do it? I can do the maths part easy to work out what each one SHOULD be but how do I get it there?!

 

[Spud]

there are several ways of doing it the top rise height being larger isnt a major issue ,what type of tile will you be using on the stairs

 

[JLM Tiling]

Porcs, not sure how thick

 

[JLM Tiling]

The top one is 179mm, the rest are around about the 174mm mark with the very bottom being 160mm. What is the tolerance according to BS do you know? Cheers for all your help with this one Gary it is starting to click me thinks!

what size 60x60?

 

[JLM Tiling]

I think they're 600x600. Bigger than the steps, thats all i need to know! And the customer wants to have one full tile centre and then a cut either side of it just to make it even more complicated!! Loving it

if its outside, than you do 2-4mm fall for water to run off. so you can win some mm. on than and some on risers. As Gary said , work on average. I know stairs sometimes hard, when they are diferent sizes and not paralel etc.

I would cut a gauging template and start from the bottom ,which i know is counter intuative but works for me when tilng stairs that are badly out, the guaging template is cut to the height of 2 step heights and the depth of one step cut away to form right angle which you can use to set each riser at exactly the same height and spacing away from one another once the riser are set you can back fill these with sand and cement and slurry the treads on here as picture of one i did like this a few years ago

I like the gauge idea, very nice. Only problem is getting around the curve. I'll take a photo tomorrow so I can show you what I mean. I'm gonna have to come up and out by at least 10mm to get past that in itself. I'll do that first so I've got a square angle to work from and then do it the way you say. Props for the advice mucker, helped clear it all up in my noggin. I'll take pics tomorrow and show you how it comes together. Might even go for JOTM!
