Working on a office stair case and is been done dot and dab. Were the steps of the stairs are I will
have to cut the board to the profile of each tread of the stairs. It's going to be a fecker to do any tips if you have done this sort of thing.
 
They usually have a piece of timber running up the stairs afterwards if not just make a profile and use it on each board.
 
I would get shot if I rolled up with a can of foam LOL. I suppose will have to get my maths books out and work out the angles.
 
It works Henry, blow the foam in, let it dry and cut it flush with the board. Scrim the joint and skim. If necessary caulk the stair/step to wall joint. I've done scores of them for Barrats etc before timber frame came in. It saves ages of precise cutting of each board and ensures no gap between board and riser
 
The stairs a pre form concrete, the stairs are not flush with the stair wall so a stud was built but the fecking joiner did not leave a space for the board to slip down the stud and just but upto the stairs tosser.

Used to work for a firm called c+g plastering in the early 2000's. Fooked me back up so they let me do a bit of snagging etc till me back got better.
anyways on the timber frame houses they had a crack that consistently kept coming back where the board (same prob as you ) met the stair string.
they kept sending spreads (well Albanian agency) to repair crac then repaint. I did a few pumping in foam so that it stuck to the back of the boad and also the back of the string. No cracks lol

Agent asked me to show them how I was getting no cracks and I said I will if you book me in twice for the same week. He agreed cos it was working out cheaper than getting agency muppets back in over and over. He was gutted when I showed him :RpS_thumbsup:
 
One word of caution. Keep your eye on the boards as the foam keeps expanding as it cures, so your boards could potentially be 'all over the place' if you tamp them and move on to the next one. Been using the Dryfix foam equivalent this week for sticking laminated insulation plasterboards to uneven stone reveals. Had the luxury of a timber stud at the front of the reveals to screw to, but no screw fix at the window frame. Obviously there is no damp transfer through the foam like you would get with board adhesive.
