Can You Sand Concrete?<\/h2>\n

Considering the nature of concrete and how hard it is, you may be asking the question, can you sand concrete with regular sandpaper? While it is possible to sand concrete, both ceramic and aluminum oxide sandpaper are less than ideal for concrete sanding. Ideally, you want to use diamond sanding or polishing pads. These pads are available as a concrete hand sander as well as grinder attachments. Diamond cup grinding wheels are available for angle grinders. These are effective when it comes to concrete sanding.<\/p>\n

Reasons for Sanding Concrete<\/h2>\n

It comes as no surprise that one of the most frequently used building materials is concrete. It has been used for centuries and has remained a trusted material for exteriors as well as interiors. There are a few reasons why one would want to sand concrete. Let us take a look at the main reasons for sanding concrete.<\/p>\n

\"Need<\/p>\n

 <\/p>\n

Salt and Pepper<\/h3>\n

This finish requires some extra work. To reach this look one will have to remove about a 1\/16 of an inch layer of concrete. The goal is to remove as much concrete without exposing the aggregate. This will leave behind a black and white speckled, salt and pepper look that resembles polished granite. This finish is ideal for countertops and floors alike.<\/p>\n

 <\/p>\n

Removing Imperfections<\/h3>\n

Concrete is an extremely hard-wearing substance that is made by mixing coarse gravel (sometimes called aggregate) with water and cement. After the concrete has cured there are often sharp edges or imperfections such as aggregate that protrudes or high spots. These issues can be fixed with some sanding.<\/p>\n

It is a good idea to smooth down sharp edges or jutting aggregate, as these can cause injury to persons or damage to car tires.<\/strong><\/span><\/p><\/blockquote>\n

 <\/p>\n

Stain or Coating Removal<\/h3>\n

Oil or glue stains and even old coats of paint can usually be removed with detergents or paint strippers. However, sometimes a stain or a coating can prove to be extremely difficult to remove even when using some of the strongest chemicals on the market.<\/p>\n

\"Concrete<\/p>\n

It is in this case that one would look to more abrasive methods such as sanding. When sanding over a stain or old paint one is essentially removing a layer of concrete that will take with it the stain or paint leaving you with a fresh clean surface.<\/p>\n

 <\/p>\n

Sanding Post-repair<\/h3>\n

Old cracking and pitted concrete can be repaired with various filing methods such as crack filler. Once the repairs have been made to the concrete surface there may be high spots or imperfections in the filling medium. Sanding over these areas will help remove any high spots by leveling the surface. It is important to note that the concrete crack filler<\/strong> <\/a>might differ from the color of the concrete even after standing.<\/p>\n

Applying a concrete stain or paint will solve this issue <\/strong>.<\/span><\/p><\/blockquote>\n

 <\/p>\n

Finishing<\/h3>\n

The most common reason for sanding concrete is sanding to achieve the desired look. It is common practice to sand concrete before applying a stain or coat of paint. This helps to achieve the desired surface profile that will increase the adhesion of the coating or stain.<\/p>\n

\"Sanding<\/p>\n

However, this can also be done through the application of an acid wash. There are also a few looks that one can achieve depending on how much sanding is done. Let’s take a look at them.<\/p>\n

 <\/p>\n

Smooth and Polished<\/h3>\n

A smooth finish can be reached with light sanding and polishing by hand or with a random orbital sander. This finish is the easiest to achieve as you are essentially just polishing the surface of the concrete without removing much concrete at all.<\/p>\n

This polished, shiny finish is ideal for countertops and other work surfaces.<\/strong><\/span><\/p><\/blockquote>\n

 <\/p>\n

Exposed Aggregate<\/h3>\n

Taking it one step further, as you might imagine, will require even more sanding. To accomplish an exposed aggregate finish on concrete you will need to remove up to a quarter-inch layer of concrete. This is a near-impossible finish to achieve by hand.<\/p>\n

You will need a power tool to achieve this finish. This is an ideal finish for driveways and garage floors as it provides greater traction.<\/strong><\/span><\/p><\/blockquote>\n
