Part 2: Building Stair Treads and Landing Platform

Without further, a do let’s start a custom-built stair rail. It’ll be gone a lot of fun. You can find southern yellow pine wood in South Georgia and Northern Florida if you live in a Florida Southern region. So your home will be adorned with tongue and groove pine panels that are the focal point of the interior. So let’s start it out.

First of all, if you didn’t find yellow pine anywhere, then you can import whitewood from Canada. But you can find the pine in different lengths like 2 by 4, 2 by 6, and 2 by 8.

So let’s rip down 2 by 8 pine wood to make the thickness of a three-inch stair. For this, we’ll make a 36-inch cut.

rip down pine wood to make stairs

Now rip these in half and then trim off the edges. Basically, you need to do a lot of cuts per piece; it’ll give you flush square-off edges where you need to sand and plain down to make a good-looking laminated piece.

Now after trimming all the wood as per the size you want; now run it through a planer to make each side smooth.

smoothen with planner

Gluing each wood together. However, as in the picture, wood with big lips and gashes will not stick to another wood. So run that wood to the planer again to get a smooth surface. If you’re looking for a planer, we recommend you buy through VEVOR due to their cheapest price.  

You will need twelve or eleven and a half inches of boards for this project. Firstly, you must take three pieces and glue them overnight; that way, all the edges will line up and look nice. You need to do this twice.

With the help of the applicator brush, add the glue on the surface; don’t pour the glue as it’s. Why shouldn’t I opt for running thread and screw these woods? Because by gluing this, it’ll sit on the metal surface and support it, and many people know this well.

Now after gluing the two wood pieces, glue the third one to clamp it together.

Now you need to clamp the wood strips, which edges you ripped. Glue them and tighten them up with the pile. Just stop clamping the wood when you get the real measurement. Our planer is 12 and a half inches, so we just stopped gluing the wood, and it’s now 12 inches wide. Furthermore, after a night, unclamp them.

tighten clamped wood

With the help of a chisel, remove the glue that is squeezed out on both sides.

remove excess glue

Now run your boards through the planer.

When getting the same thickness after planning them, the next step is to chop saw them, square off the ends, and remove any glue or irregularities.

Now with the Woodworking triangle, mark the edges with some knots that give bad structure to the wood.

Again glue all the pieces and leave them overnight after clamping and tightening them, and the next day, remove the glue with a chisel and sandpaper.

glue and clamp all pieces

If you get any cracks, fill the holes and cracks with the DRS material; it only takes a few minutes to dry. Then sand your board with 220 grit and clamp them.

Again you need to remove the clamps, remove the extra sand, and run it through the planer.

fill cracks with drs material

Do a finishing with the cordless router.

Now you can see this wood is as same as we bought it in its original form. Therefore, if you find yellow pine, just do a ploy coat on wood and follow the same procedure as we did.

repeat procedure

Now with the help of painter plus, we spray the boards and use a Polyurethane spray. Don’t forget the underneath area; these are floating stairs, so you can clearly see the bottom. Usually, vertical spaces need two coatings, so make sure to do an even coating on that. First, spray vertically and then horizontally, and cover all the boards carefully.

You’ll see a golden color on the board, as just you see in the picture. You can choose the base as per your house color and do a double coating if you still see spots on it once it gets dried.

The drying time is fast; you can do the second coating after three to four hours.

Part 3: Metal Work and Finishing Of Landing Platform For DIY Floating Stair

You will need to concentrate on the metalwork to construct a floating staircase. So need to consider several things, such as cutting steel with different templates and hand tools.

Before installing stairs, just remember that different quarter, space, states, and attic spaces have their own rules, so follow these before installing stairs. But here we’re, following six feet and six inches in height. Furthermore, you’ll notice the same height with a door opening itself.

If you see the post has contact with the concrete slab and go down, weld it and measure the post from the bottom. But we’re down to six feet and made an eight and a half inches line here and then put a brace in it.

You’ll not use the 45-degree brace immediately, but it adds strength. In this case, you will face the challenge of laying the thick steel where the base height is limited to a flipped-over position.

So placing the base will not comply with the regulations, so scrap the wood piece to the desired base endpoint. Take a measurement of 6 feet and 8 and a half inches. To determine the appropriate angle mark the line and create a template. Now transfer this measurement and angles to the steel for cutting. Manual cutting will be necessary if you’ve incredible tools like a chop saw and bandsaw stands.

To cut the other end of the steel, you must use a VEVOR portable band saw.

weld out metal pieces

Welded out all the metal pieces.

drill holes in plates

Let’s drill the holes in these plates and set and secure treads using lad bolts.

weld railing base

It is now time to weld the feet, or base, of the railing.

cut plates to support underneath treads

Make sure to cut the tons of plates to support the tread underneath the sides.

install metal plates

Now install these metal plates with ranch on a tread.

cut and fix small metal sizes

Cut small sizes metal pieces and fix them below the horizontal plates by welding.

drill holes from the edges

Drill the holes from the edges.

Part 4: Painting and Installing of Wood Pieces and Stair Tread

Remove the welding residues using an 80-grit flap disc attached to your grinder. To refine the surface, you’ve to shift to a 120-grit disc.

So before proceeding with painting, you need to do a polishing process and eliminate the remaining weld splatter and lingering rust. For this, you’ll need to do a sandable and high-build primer coating along with blackish rusty oleum paint. This will only need to do on highly visible parts.

Use lacquer thinner to remove oil from the metal, as it removes the extra residue.

Once you remove the metal, you will notice a thick layer of oil and nastiness. Wipe your entire metal piece.

use bondo incase of cracks

Use Bondo on the metal if you get any cracks in the metal while working. Now after this run a cordless router over a metal piece to make it smooth.

Purchase metal countersinks, as this kit includes a range of sizes to accommodate you. Using these countersinks, you can securely embed thick wood screws, such as those with concave heads, in areas that will bear weight. To ensure protection remove the material carefully so that the screw level is flush with the surface before putting the screw in.

purchase metal countersinks

By taking your friend’s help, install a landing platform. You’ll need to cut out some of the trim and flooring for this. To better contact with concrete cutting out the floor. Post if you have a three-by-two-by-four wall to bear the wall. Using long lag bolts to secure it since the two-by-fours are angled. So it’ll allow it to align with a footer on the floor.

Cut and remove the tile from the wall; you can use an old blade without teeth for this purpose. By doing this, your post will make contact with the floor and concrete.

cut and remove tile from wall

Now put your stair railing in the post and screw them after drilling the holes.

put your stair railing in the post

Pull the ladder and use it to fix the stairs bolted to it with a few people.

use ladder to fix stairs

Mounted the floor against the stairs and fix stairs feet by adding concrete anchors. As for the post, you’ll need to anchor six eight-inch-long lag bolts into the wall within a strong five-inch-deep wooden structure. The floor joists must be secured with log bolts, three sturdy wood screws, and an angle iron edge.

anchor lag bolts

Install the boards and screw them along with a stair. For your stairs not to loosen up, drill holes in the wall and add a board to them.

Part 5: Floating Stairs Railing Installation

It’s time to install the railings of your floating stairs. The inside railings can now be constructed once you have taken measurements.
