Hello all,
My staircase was covered w/ carpet and I am replacing it with oak wood treads and mosaic tiles on the risers. It has few steps w/ curved front. The tread is 44" wide, and the middle point is pushing out about 2" further than the ends.
The risers are made of 1/2" OSB so that they can bend to follow the tread's curve. If I put my knee against it, it flexes, and I am concerned once tiles, the grout lines will crack. I am thinking of re-enforcing them and I see 2 options.
1) Glue another 1/2" OSB in front of it
2) trace the contour and transfer it to a 2x4. put such block behind the riser. One at the top, one at bottom.
Please let me know if there are better ways to re-enforce them.
Thanks much
