How to make concrete beautiful

The words beautiful and concrete don’t often appear in the same sentence and for obvious reasons.  Concrete is grey, dirty, dusty, dull and ugly.  Isn’t it?  Well not necessarily.  It is possible to make even commercial concrete attractive. 

If you are building an office block with a large atrium you might want good looking concrete. If you are building a shopping mall with large areas of flooring that will endure many millions of shopper’s footsteps then an attractive concrete floor is the perfect solution.

If you have a large showroom an attractive floor could well be appropriate.  And concrete is always going to be cheaper than marble tiles. 

So how do we make concrete beautiful?

Coloured concrete

Concrete does not have to be grey – it can be any colour you want; green, blue, red, yellow or even black!

To produce a coloured concrete simply add a pigment, usually in the form of a powder, to the concrete mix.  The pigment is usually a metal oxide and the market leader is Bayer with their coloured pigment range – Bayferrox.

The ratio of the mix is one part pigment to 25 parts cement.

The colour of the cement is critical in the final colour of the floor.  A traditional grey cement is fine for dark colours but for light colours here at BECOSAN® we recommend using a white Portland cement in the concrete mix.

Using aggregate to give texture

The selection of aggregate in the concrete mix can enhance the appearance.  There are three basic types of effect; Surface Cream, Salt and Pepper and Exposed Aggregate.

Surface Cream

The exposed surface of the concrete is made of a troweled cement paste with sufficient depth so that after polishing no aggregate is exposed.  This is very popular and will give a concrete with a uniform and consistent colour and with no imperfections.

Salt and Pepper

This finish is achieved by using a fine aggregate and only grinding down to the level of the top of the stones.  Usually, this requires only about 2mm of grinding.

Exposed Aggregate

Here we select a visually appealing stone and expose the centre of it by grinding down by up to 6mm in depth.

Care must be taken in the selection of the aggregate to expose.  It should have a regular size and have a colour inside complementary to the colour of the concrete. 

The most popular decorative aggregates are interesting coloured natural stones such as basalts, granite, quartz, or limestone. One can also use manufactured materials such as recycled colored glass.

However, stones that contain iron oxides or iron pyrites should be avoided as their colours can leach into the concrete.

Polishing and the BECOSAN® System

So you have a beautiful blue floor with coloured stones embedded within but we can enhance the floor further by using the BECOSAN® system.

The BECOSAN® system uses diamond pads to polish the floor to a high gloss finish so that it feels like glass to the touch.

However, it is still concrete and wear and tear will damage the surface and will produce dust if left untreated.  To counteract this we apply the BECOSAN® Densifier which binds with the lime in the concrete to make it resistant to abrasion and harder wearing.

Finally we apply BECOSAN® Protective Sealer which makes the floor resistant to liquid spillages.

A concrete floor treated with the BECOSAN® system will last for very many years and will give a surface comparable to any marble floor and at a fraction of the cost.

A BECOSAN® floor requires little maintenance. The increased hardness and durability mean it is less prone to becoming damaged or cracked. This means that your business processes do not need to be interrupted to conduct repairs to the floor and cleaning is rapid and at a lower cost.
