Select the suitable stairs finish is a hard mission, especially for homeowners. There are a variety of finishing materials, details and style. Marble is the common use material that is strong and has a nice appearance despite it classic style. Personally as much as I love marble but i struggle to find a modern details. The shadow line detail is a method to get a modern appearance, that is suitable for the most type of marble. The shadow line has flush clean look with no overhang nosing to have a modern appearance. With a thin black granite underneath the riser, it shows each step by itself individually.
when to use the shadow line detail
As mentioned before the shadow line detail is suitable with many kinds of marble. It’s the best choice with marble that have different tones like Flower Beige marble as shown in the below photo. The shadow line detail will separate each step by its own, then people will not easily notice the difference in marble tones. Also it’s suitable with marble that has many veins, it displays the beauty of each step. On the other hand, it’s not nice with clear marble that look similar tone and doesn’t have veins. It’s not a bad choice but it won’t add much to the marble and stairs.
Installing shadow line marble stairs
The shadow line detail is simple and cheap detail comparing to another marble details. Because its regular straight steps with a 2cm black granite underneath the riser. Granite is prefer to used and not marble, because it’s thin we need a plain black color. Also granite is more rigid material to avoid the break the 2cm piece through cutting process. Personally I prefer black shadow line to be thinner than 2cm but then it will become weaker. There are three types of black granite, beside artificial stone read How to Select Black Granite article for more information. Artificial stone is not suitable because it will efflorescence and appear with with grey and white spots. The craftsmen need to cut the granite using saw cutting machine at marble factory, and then to glue it with the riser according to floor and riser height.
In conclusion, It’s not the only modern marble stairs detail, but it’s suitable for marble that has variety of tones or density veins. The shadow line detail is cheap compared to another modern marble stairs details. Also it’s well-designed, the design is avoiding water collecting and has no fine details that could break in the future.
Selecting proper tiles for stairs is a hard mission, because stair is in high traffic area. Designers choice a high strength cladding material like granite because it’s solid. Due to high price of granite, usually people choose the cheapest granite type. Rosa Beta, has a low price because it doesn’t look nice, traders says “Rosa Beta is granite in marble price”. Using marble is the next option, but marble surface will scratch and fragment due to stairs’ high traffic. However marble is weak and nice, but could maintenance easily by grinding and polishing it surface. after maintenance and renovation marble will look as it’s installed yesterday. Porcelain tiles is economical choice, it’s artificial material where tile body could be different from tile’s face according to different types. This post will cover how to select tiles for stairs, what are riser and tread connections types and how to install stairs’ tiles.
How to Select Porcelain Tiles for Stairs
Selecting the proper stair tiles is a sensitive mission. Take in mind few things while choosing stair’s tile: the tile’s classification, the size of the tile, the glossiness, and finally choice anti scratch tile.
Do not use ceramic tiles, ceramic body is weak and stairs has high traffic. Also ceramic’s body color usually is red and this doesn’t fit the connection between step’s riser and tread. Even for porcelain’s tile Choice full body tile or color body’s tile.
Choose proper size tile’s to fit stair’s width. In market, there are tiles in size of 120*40 cm and 120*60 cm. These tiles size fit with stairs’ in width of 120 cm or less. Using small tile’s size isn’t recommended because tiles will be weak and easy to break.
Choosing matte tile’s or high glossiness, depends on the context design. Personally i don’t like glazed porcelain, because glaze layer is usually wave. Matte tile’s is a better choice especially for riser and step tread connection as we will discuss in the next paragraphs.
One last thing to take in consider especially for high glossiness glazed tiles. Due to stair’s high traffic, tile could scratch, it’s recommended to choice anti scratch tiles. Also you can test scratch resistance at material lab.
Stairs Tile’ Edges Types
The difference between marble and porcelain, marble’s edge could polish to have safe edge in nice finish. This due to marble’s body and surface are the same material. When it comes to tiles, even full body tiles, tile’s polished edge glossiness won’t appear as nice as the surface glossiness. Therefore designers look for special edge details for riser and step treads that fit porcelain material. There are several types for edge details either by installing tile trim or polished porcelain tiles: bull nose type, straight riser, or to use advanced details like Costa Retta or Gradone types.
This by installing a porcelain, metal or stainless steel tile’s trim at the connection between riser and step tread. The tile trim will have a hard edge however it doesn’t have a high aesthetic value.
This type of stair’s tile, by cut and polish the edge of step tread in round or semi-round end. The edge will be safe and hard to break. On the other hand, the tile has to be full body or color body, to allow edge polishing. Another disadvantage of this type that not all tiles contractors could implement it, because it requires special machines.
Straight or Angled Riser
Simplest way to install stair tiles. Where riser installed at right angle or acute angle to improve the safety of the staircase. In case of acute angle, craftsmen create a template to install riser, this makes the job easier and aligned. In right angle, tread lay over the riser, and 45 degrees edge use when tile’s body difference than the surface. It depends on the quality of tiles, remember that 45 degrees edge connection is weak.
Straight Nose (Costa Retta)
This by creating a detailed step nose from several tiles pieces. Implement this type require an experienced craftsman. The void of nose is filled with cement mortar. Costa Retta is Italian word mean straight nose, this type has a high aesthetic value.
Large Step (Gradone)
This method also has a step’s nose but it’s simpler to implement than Costa Retta. This by gluing a tread as shown in the following photo. Gradone mean long step in Italian, also this type has a nice appearance.
Installing Tiles on Stairs
Installing stair tiles need a professional, he needs to also calculate the height of stair’s risers. Then making few millimeters slope at step’s tread toward downward. Tread slope is necessary to prevent water from collecting on each stair tread, for long periods of time. Tiles laid over cement mortar, and below the mortar a mix of sand and cement in 1:1 ratio. The cement and sand mix, will be a concrete when water reaches it through tiles or tile’s grouts. The last important thing to implement is anti slip lines at each step, this is necessary for outdoor and glazed stairs.
Conclusion this, installing tiles at stairs is economical but has to choose the right tile and install it the correct way. The following photo is porcelain tiles’ stairs installed 13 years ago in high traffic outdoor restaurant. Thousands of people pass through this staircase daily, the stair situation still good compared to it low price.
The staircase is the focal point inside any space, designers like to make staircase the aesthetic element of the space. Staircase is expensive because it large scale especially when cladding with marble or granite. Also designers like to enhance the beauty of the staircase by adding some elements and design techniques. Stairs Lighting is one of the most important techniques. Lighting could be target on the steps or hidden inside the steps, other designs depend on handrail lighting. This topic will discuss stairs hidden lighting type and its construction details.
