Wooden stairs without footrests
Wooden stairs are a decorative element in the architecture of residential interiors. The stairs are well made then, when the steps do not creak or twist.
The design solutions of the stairs are various. They depend on the spatial possibilities and creativity of the architect.
Stairs without footrests.
Solid wood stairs, without footrests, are the simplest solution. The supporting structure consists of a steel or concrete central carrier or two carriers, whose spacing is shorter than the length of the steps.
Machined logs are used for the steps. As the steps are generally wider than the logs, they are glued longitudinally from several logs. This allows all defects to be removed from the material. Always cut the closest area of the core from the middle logs, i.e.. about 3 cm.
An important element of wide machining, massive material is good drying and conditioning of the wood (for approx 1 month).
Machined steps, sanded along the grain, should have rounded top edges to the radius 4 mm. The lower edges may be less rounded, e.g.. 1 mm.
The surface treatment of the steps should be carried out prior to installation. The first coat is varnish, the next two - epoxy varnish.
Instead of solid wood, the steps can also be made of chipboard, veneered. The supporting part in this case consists of two chipboards glued together. Both boards are glued on all sides, except for the front plane, thickness veneer 1,6 mm. A strip of wood of the same species as the veneer is glued to the front surface (the figure on the right).

The method of kneading chipboard steps is as follows. First with a thick board 19 mm steps are trimmed, according to dimensions with a reserve of at least 10 mm and sticks two pieces together. One of the longitudinal sides is processed on a planer and a wooden strip of approx 5 mm. The width of the strip must be greater than by 2 mm from the thickness of the glued boards. After the adhesive has hardened, the protruding part of the bar is ground or blown apart. The lower and upper surfaces are veneered at the same time, and only then the other three side ones. After grinding and rounding the edges, the boards are varnished.
Veneered steps compared to solid wood steps, have a number of advantages. They are uniform across the width in appearance, Flawless, and mainly they are constant in volume and there is no danger of warping.
The varnish coat is always renewed before rubbing down to the wood itself. If, however, such a clash took place, then the steps must be dismantled, Remove any paint residues on a belt grinder and apply a new coating, similar to the new steps. This process is made possible by thicker veneers.
