Exposed Aggregate vs Coloured Concrete? 11Jul 24, 2012 6:36 pm Getjason Gotta laugh at some advice but all good if your going to add oxide ( colour ) to your mix design be prepared for it to A fade quick and B be inconsistant , if your lucky you will get neither , When choosing your sealing element dont go to a high solids content ( glossy ) finish as this will become very slippery on the smooth stone when wet . Remember to retain the colour if chosen you will need to replace the sealer every 1-2 years, ThankYOu mr UV only issue with living in this part of the world , make sure when you seal its not too soon or to much moisture causing delamination and peeling . God i love CONCRETE , here all year try the fish just got to pipe up again re the above, It sounds like this advise relates to a bad job you have had done? If done properly there will be no inconsistency in colour. Wet concrete is a much more intense colour than the final product hence fading quickly as it cures is normal. If it fades too much then not enough colour oxide has been used or a cheap brand that is not iv resistant has been used. Or your concretor has not properly prepared you as to the final expected colour for your dosage. If slipperiness is a concern exposed is the most suitable surface and can give great grip on steep slopes. Sure your not talking about polished concrete being slippery? Re: What is better?

Rory , you saying that colour thru concrete is the right colour everytime and all the varibles that come into play when placing doesnt effect the overall look ? UV resistant pigments ? If you can give a 100% consistancy warranty on colour thru i can get you so much work for Mirvac , i see more coloured sealers trying to fix failed colour thru than good consistant job and i dont make the failed jobs i fix them :) Re: What is better?

Because the finished surface is not seen until the concrete is exposed the day after the pour it hasnt been trowelled (which lightens the colour) or seen the elements during the pour. And no I dont get variation in my regular colour through as I have made all the mistakes in my youth (and never again fingers crossed). I havent had to reach for the colourseal for many years. Last time it happened the day was hot and windy and the concrete a double dose of black. All was going to plan when the owner let his chiuaua out. We had to fix hundreds of little chiuaua footprints before we could stipple. Anyway these days no more taking risks incase the unexpected happens. Its all about consistency. Same doses, same slump, not trowelling bleed water into the surface, not throwing water onto the surface when the concrete is getting too hard to trowel. Not letting the concrete get too hard to trowel! Having an evenly moist subgrade, not pouring half in the shade half in hot sun, having a capable crew with enough hands on deck. Not pouring on a windy day, finding a reliable concrete supplier, reminding the customer to keep the dog inside, and the list goes on. There is always the potential for disaster in concreting with so many variables hence why your fixing so much. And builders tend to hire the cheapest subcontractors and use the cheapest materials they can find. Which is great for the kids who are learning. (thats how I learnt the trade) Not so good for the customers. And even the good concretors they hire they are not paying them enough to fund a proper size crew and use the better materials so they have to cut corners and get through jobs quicker, hence the difficulties. They would probably not want to pay the extra $5 or $10/sqm for me. But yes I do guarantee my jobs. And I could guarantee colour consistency as my jobs are consistent in colour. Although Its good they are using colour through. I cringe when I see a new house go in with a plain concrete driveway and 1 coat of colourseal on top. Re: What is better? Exposed Aggregate vs Coloured Concrete? 14Jul 28, 2012 9:15 pm I am hoping you guys might be able to help me... which is more expensive - in colour concrete driveway or an aggregate driveway. Or alternatively, is a crushed pressed rock driveway cheaper than either of these? Thanks Re: What is better?

Or alternatively, is a crushed pressed rock driveway cheaper than either of these? Thanks Aggregate costs more. I have an aggregate on the driveway, and some coloured concrete in the alfresco. I could have saved some money by downgrading to coloured concrete for the driveway, I'm glad I didn't Re: What is better? Exposed Aggregate vs Coloured Concrete? 16Jul 31, 2012 8:57 pm Another option to consider perhaps which I have seen done very successfully is to have poured limestone which has a coloured oxide or something through it. The colour I have seen is a dark charcoal which has faded slightly over the last 5 years but still looks lovely...
