I’m looking at cast stone bands instead of brick coursework around a brick house. Also around all the windows and doors. Anybody have experience using it in these applications? Any “heads up” on the installation? Is brick better?
And how long has this stuff been around? I know it’s supposed to be stonger than the limestone it’s made from, but I’m skeptical. Limestone crumbles and down here in Georgia we get lots of rain, humidity is a killer. So, ugly mold could be a problem too.
Thanks!

B.J. I have used the accents on arches ,door.and window corners I think we are talking about the same stuff. It is heavier than cultured stone and fairly brittle but all depending on the applacation some of it installs like cultured stone whereas some instances you have to use a form support because of the weight, on arches I have used the forms to give me nice clean lines around windows and doors ,but on corners "quions"I use whatever material i,m using as a ledge to install it. the material i have used was made out of white sand and white portland with small aggragate.
Thanks. It must be the very stuff I'm looking at using as trim in a brick house. The spiel on it goes: < Cast Stone is a masonry product made from fine and coarse aggregates, Portland cement, mineral oxide color pigments, chemical admixtures and water. Properly manufactured, Cast Stone has the same or stronger physical properties as most dimensional building stone.> etc. and it can last for decades. Brick Institute says you need to break the bond between the stone and brick because the 2 move differentially. And use a flashing above, but not below, the stone when using in a band. Sound right?
B.J. I have seen what you are talking about and yes that is what they do , as a seal between the flashing and the band use silacone chaulk or I have seen no flashing used and just silacon used which is what I do around the material I work with,might not be right but it works for me .I worked with a fellow last summer that had worked, caulking the world ball at Disney's epcot center he told me sincr then he had been called back to reinspect the work they had done to the sphere 30yrs before. He said that they had used 100% silacone chaulk and that it was still holding up with very little repair needed. I know that w. Handy and co. carries a lot of differant colors of silacone chaulk if you need tp match colors.
Great! Love that silicone.
"Brick Institute says you need to break the bond between the stone and brick because the 2 move differentially."
Hasn't brick been mortared directly to steel lintels for forever?? Doesn't steel and brick move differentially??

The more I think about it, the more I think why mess with it? Just re-read what I posted from the people who're pushing it and they're claiming it can, if properly installed, last for DECADES?? And I'm gonna substitute that for brick?I think not. Think I'll do the brick coursework everywhere and maybe use a real stone keystone over windows on the front. Enough quarries around here to get local stone. Good plan?
Where will the water go?
I recall an article in FHB on cast stone and such. Seems that it passes water to the inside and needed to be treated like stucco - with a weep screed for moisture drainage. When the need for drainage is neglected, you get rot.
Nice pix of a fancy home with a lot of this stuff - and rotted OSB behind.
There was a nice add for the stuff in current FHB - a New England field stone house. Looked very nice. Could not see what they did for drainage.
