Concrete Finish

Introduction

Concrete is an extremely versatile material that can vary its appearance based on finishing, forming, and other things such as additives for tinting.

One thing to always keep in mind is a timeless saying that there are two types of concrete:

• Concrete with cracks
• Concrete that is going to crack

It's because of this that many different finishing techniques and control joints have been developed to help shape the aesthetics and control the finish over time.

As-Cast Finishes

Rough Form Finish

The simple method of leaving the concrete as is when the forms are removed. This shows the formwork and joints between forms. Defects and tie holes may be left unfinished or finished. This is essentially forming the concrete with just ‘normal’ forms, while the next is more about aesthetic special finishes.

Smooth Form Finish (See Form Liner below)

Similar in that the profile of the interior of the form will be embossed in the face of the concrete. Smooth forms of wood, metal, hardboard are used and the joints and tie holes are planned so that they are symmetrical or have a nice design logic to them.
