They were actually used on 2 of my projects in part of the project not in our scope of work but under the landscaper who was a separate contract to the Owner - a pool deck. We had no say in what was going into that area, but did watch it going in. There were no problems and everyone has been happy with it. Then can also do patterns/stampings/scorings. Unfortunately, their web site is mostly about pictures and showing the application graphically. The do national installations. Their main location is in Dallas, TX. But they have work all over the east coast, west coast and in betwen. William Jerome J.

Both of these manuf are Florida based. Call them and ask about your dilemna. If you decide to use SunDek, provide your email and I can email you a package we received on a recent marriott project. Sraycrete has a very good website.

I just tried going there and my anti-virus app told me the site is infected with a Trojan virus. Don't know how valid the warning is, but I think I'll stay away for a day or so!

I had an Owner asphalt pave over the white cement, white sand and limestone aggregate concrete paving picked by the designer. Looked good for only a month. then there were black marks in traffic lanes that could not be eliminated Anonymous   Posted on Wednesday, November 19, 2008 - 09:51 am:    Using white concrete for vehicular paving would be like a wearing a white linen suit to change a tire...

Howard Jancy (Unregistered Guest) Unregistered guest Posted on Wednesday, November 19, 2008 - 05:26 pm:    Prepackaged cementitious overlays (sundek and spray-crete) are a good choice if thickness is a concern. They are generally applied from feather-edge up 3/16", depending on the manufacturer. A concrete topping - supplied by a ready mix company - typically is applied +/-1.5". (A local ready mix supplier should be able to supply more details about thin concrete toppings.) So, the prepackaged cementitious topping should be cheaper than the ready mix supplied material based on volume of product. Also, ready mixed concrete made with white cement, instead of standard gray cement, will also increase the cost. Also note, the cementitious overlays become very expensive if you are using them in thicknesses over +/- 1/2". (Could vary by manufacturer) The cementitious toppings require application over clean and structurally sound concrete. If this is not the case, failure is likely as the surface is subjected to traffic and temperature cycling. The thicker concrete topping would be less prone to problems. Also if you are in a snow belt climate, snow plow blades, unless rubber edged and/or riding on feet, could more easily delaminate the cementitious topping as opposed to the thicker concrete topping. On the topic of repairs, the cementitious overlays could be an easier task with regard to cost and being visually less obvious compared to a concrete topping repair.
