Exposed Aggregate Vs Stamped Concrete

Exposed concrete is a very decorative style of concrete design that also gives a non-slip texture to the structure. The aggregate particulate matter of the concrete is remarkably visible in the top layer of the concrete giving an impressive attractive finish to the concrete structure. It is used in various places such as driveways, patios, and sidewalks.

The exposed aggregate concrete mix is ​​essentially the same concrete mix that is generally used. The concrete top surface must be worked well enough to create a good cream layer on the top surface. Without water on the top surface and concrete thick enough to allow for a ½ “thumb depression, the colorful gravel / pebble granules or your choice of aggregate should be spread evenly across the surface. The top layer of cream would not be adequate. Soft enough to hold onto gravels / pebbles, a damp mixture of sand and cement (3: 1/4: 1) should be applied over the spread pebbles / gravels. The gravels / pebbles should be pressed into the concrete with a uniform and medium pressure using a wooden float so that the flat surface of the gravels is facing up and the full shape of the gravels is visible.The top surface should be finely brushed and then cleaned to expose the shiny aggregate.

Exposed aggregate concrete is slip resistant, strong and withstands extreme conditions. This surface requires very little maintenance other than resealing and flushing annually. Adding coarse aggregate to the top of the concrete and towel mix makes the wear surface very thin and that is a disadvantage of this design.

Stamped concrete is a decorative style to give stamped concrete Greenville sc structures a unique look. The concrete mix is ​​repeatedly stamped with various molded shapes to give a uniform stamped appearance. This variety is used on sidewalks, driveways, patios, or sidewalks.

The concrete mix is ​​poured into the construction area, spread and leveled. Excess bleed water is allowed to evaporate from the concrete surface. When the concrete surface is firm enough to allow a ½ “thumb depression, it is ready to be stamped. Stamps are widely available in the market as rubber stamps, wood stamps, etc. The first stamps should be placed in the concrete surface and be pressed just enough and not too hard by hand alone. Other stamps should be placed snugly on the first and once in a row to fully cover the area and be handled by hand. Once all stamps have been placed , seals should be removed from the first placed seal very carefully without disturbing the other seals, concrete sealers can be added for durability.

It is really economical to apply stamped concrete as stamps are readily available and any shape can be used as stamps. Gives a great look to concrete pavements and patios with ease. Single or dual tone colors can be made in this type. This type of concrete is very susceptible to antifreeze agents and deteriorates very easily. It also loses shine and luster more quickly than other types.
