How To Expose Aggregate

Exposed Aggregate Concrete Patio and Steps in London ...

There are several ways to expose the aggregate in concrete. And a general rule of thumb is to remove the surface cement paste at a depth that is no more than one-third the diameter of the aggregate.

Brushing and Washing

This method requires washing away a thin layer of the surface cement paste by spraying it with water and scrubbing it with a broom until the desired depth of aggregate is exposed.

This method is best for small jobs and can begin as soon as the surface cement can be removed without dislodging or overexposing the aggregate. To test if the concrete is ready, lightly brush away a small area of the surface cement paste using a stiff nylon-bristle broom.

Using a Surface Retardant

After placing the concrete, the top layer of cement paste is kept soft by spraying on a surface retardant to slow down the curing process of the surface as the underlying concrete hardens, locking in the aggregate and reducing the risk of dislodging aggregates.

After several hours, once the underlying concrete sets, the top layer of cement paste is rinsed off with a pressure washer or garden hose or is scrubbed off using a broom and water.

Abrasive Blasting

Once the concrete has set and hardened, you can expose the aggregate using abrasive blasting, such as sandblasting or shot blasting. This method is not recommended if you want to preserve the colour and shape of the exposed aggregate since it can fracture and dull the appearance of aggregate.

Types Of Exposed Aggregate

There are several methods for creating exposed aggregate concrete, including:

Standard

This is the most common method for exposed aggregate. It involves mixing or batching the aggregate in the concrete mix at the concrete plant first before delivering and laying the concrete at the project site. Pea stone is one of the most common aggregates used in the standard method.

Topping

Also known as a concrete overlay, this method is used to upgrade the look of existing concrete that is still in good condition. Aggregates are mixed into a concrete overlay batch and applied to an existing concrete slab in a thin layer that is 1 to 1.5-inches thick.

Seeded

For the seeded the method, the decorative aggregates are placed by hand or broadcast on the surface of the freshly-poured concrete and then floated into the concrete by hand.

Polished

The polished method is the most common method for exposed aggregate concrete inside homes. This method is similar to the standard and topping methods. But instead of leaving the aggregate exposed with a textured, slip-resistance surface, a grinder or sander is used to work the top layer down.

Several clear coats of sealer are applied to create a shiny, polished surface. But if you want a matte finish, this step can be skipped.

Types Of Exposed Aggregate Concretes

There are two basic ways of constructing an exposed aggregate finish to a concrete the first, Surface Dressing, acheives the effect by pressing the decorative aggregate into the body of the freshly poured concrete, whilst the second, Washed to Expose, which is preferred for heavy-duty or commercial use, is brought about by stripping away the from the top 2-6mm of the concrete to reveal the constituent aggregate.

Resurface Exposed Aggregate Concrete Patio

Is it possible to resurface an exposed aggregate concrete patio? My current patio surface is about 20 years old, and the aggregate has deteriorated a bit and is pretty ugly looking and painful to walk on. Here’s a picture:

  • How much room you got to raise the slab? Can you add a couple inches without interfering with anything ?

If you don’t have to make the overlay “very thin” and the patio is structurally sound, there’s not a whole lot of “bonding” needed – a 1-1/2 – 2″ thick overlay on a sound, solid concrete substrate will happily sit there, unless it has voids to encourage spalling in the winter. As it happens, that looks like a pretty good bet for bonding to though it would probably be advisable to pressure-wash it to remove any loose material, and probably also acid-etch it to improve bonding and further clean it up.

Thin is generally harder to do well with masonry materials.

Avoid resurfacing with new. There is no way to make a permanent chemical bond, water will get in and it will crack out at any thickness that will not interfere with your use of doors and so forth. Don’t let anyone tell you otherwise. This is regardless of climate. Don’t believe me? Call your local cement supplier and ask them.
