As you can see from this photo, the treads were just plywood. I took this photo after installing the trim down the sides of the stairs last weekend. When I did that, I made templates for both the tops and bottoms out of cardboard then scrap plywood. They helped a lot by giving me the opportunity to fuss with the plywood rather than the $40(each!) 1x10s I was using for the final trim. With the prep, template making, and installation, it took the better part of a day to get these installed.
I bought the rest of the supplies yesterday from the Home Depot. I used pre-cut pine treads and 1x8 pre-primed trim. I urethaned the treads outside yesterday so that they'd be ready to go today. I spent almost an hour this morning getting the materials, tools, etc. laid out before I started and boy, am I glad I did. By the time I started, everything was at hand, which made the work go much quicker than I thought it would.
Here are the steps I followed for each tread/riser pair.
- Measured the tread and cut it to length.
- Measured the riser and cut it to the correct length and width.
- Drilled two pocket holes on the bottom of the riser.
- Attached the riser to the tread with pocket screws. This basically made them into a single unit.
- Removed the tread/riser pair and applied a healthy dose of construction adhesive to the stringers.
- Put the tread/riser pair in place.
- Screwed the tread to the stringers from below with two pocket screws per stringer. This really drew the tread down.
- Nailed the riser to the stringer (from the front) with finish nails.
- Repeat
There were 12 steps. The whole thing took about 5 hours, which I didn't think was that bad.
Here's the final product. I'm quite happy with how it came out.
