Aggregates used in OUTWEST CONCRETE'S decorative range are natural products and can vary in size, shape and colour without notice. These variations can/could also change the shade and effect of the concrete mix.
The finished surface appearance is also influenced by concreters’ techniques and workmanship. Our samples are indicative of the colour and finish likely to be achieved. We do not guarantee the finished product will conform to these samples.
The method of exposing the aggregate of fresh concrete can generate wash of water that contains cement and other particulate matter. All wash water must be contained on site and disposed of in an environmentally responsible manner. Never allow wash water to enter any drainage system or natural waterway.
OUTWEST CONCRETE recommends, after exposing the aggregate, a light acid wash and saw cutting of concrete as soon as practically possible. A minimum of two coats of a suitable sealer be applied to reduce the risk of any staining occurring on the concrete surface.
- For your Exposed Aggregate to continually look great a high pressure water wash is recommended from time to time and resealing be carried out periodically.
- Minerals in aggregate can cause staining. An approved sealer will reduce the likelihood of this condition occurring.
- Please refer to the Cement and Concrete Aggregates Association recommended practices for placing decorative concrete.
- Our decorative mixes are designed to be placed directly “off the chute” from concrete agitators. Please consult with us if you require placing these mixes via a concrete pump as mixes may have to be altered.
- If on site water addition takes the concrete slump beyond specification colour variation and aggregate segregation may occur.
- OUTWEST CONCRETE recommend viewing exposed aggregate and polished samples at your nearest OUTWEST CONCRETE display center, to ensure your aggregate selection meets your expectation.
