SWagar Posted August 6, 2009 Report Share Posted August 6, 2009 This afternoon I had the great pleasure of attending a discussion group organized by the MVMA Masonry Veneer Manufactures Association, Owens Corning and Pumalite (a local distributor). The MVMA is new trade organization that is attempting to set some standards for the installation of Masonry Veneer, aka Faux stone. One of the many things that came out of that meeting was their installation standards that were introduced in Jan 2009. Their goal is to first create an ASTM standard and then get the installation standards (or part thereof) codified. That should be a few years before that will happen. These standards are very close to the Owens Corning Best Practice Guide but are now intended for all manuacturers. Here is a link to the document .... http://www.masonryveneer.org/pdf/mvma030909.pdf Happy reading. From my perspective, this is a great thing! I can now point to some industry wide standard not just OCs Best Practice Guide. This helps when I can't figure out who made the stone I'm looking at.

resqman Posted August 6, 2009 Report Share Posted August 6, 2009 The last paragraph page 11, they do wrong everytime. Requires a 2 inch gap at the bottom and at least 4 inch above grade. "Verify that all flashing including roofing kickout flashing has been properly installed. Although roof flashings are not part of the wall cladding system, they are necessary for proper moisture management. Flashing material should extend above horizontal terminations, roofing material, and drainage planes or vent mat products. Weep Screeds and other base flashings should be held a minimum of 4â⬠Quote Link to comment Share on other sites More sharing options...
SWagar Posted August 6, 2009 Author Report Share Posted August 6, 2009 I don't think I get what you are saying. But, if you are saying there is a requirement that the gap over hardscape is exactly 2 inches. That is not the case. Quote Link to comment Share on other sites More sharing options...

Rocon Posted August 6, 2009 Report Share Posted August 6, 2009 It is straight out of ASTM C 1063 I do not understand your point. The last paragraph page 11, they do wrong everytime.

resqman Posted August 6, 2009 Report Share Posted August 6, 2009 I am saying that almost every house I inspect that has adhered manmade stone does not provide adequate space above hard surfaces and there is never a weep screen at the bottom. The documents provide a source to show the builder that his subs did it wrong. Quote Link to comment Share on other sites More sharing options...
StevenT Posted August 7, 2009 Report Share Posted August 7, 2009 The documents provide a source to show the builder that his subs did it wrong. Just like EIFS, and so many other installed materials. Quote Link to comment Share on other sites More sharing options...

Thanks Scott, this is a great resource Seems Just cause it is a dryer climate in our area, builders think they don't need flashings and kickouts or raise bottom edges out dirt, or they pour the driveway apron up over bottom edges.... guess I'm preaching at the choir, though Quote Link to comment Share on other sites More sharing options...
hausdok Posted October 8, 2009 Report Share Posted October 8, 2009 Hi, A few weeks ago, I inspected a very nice custom house that was about 11 years old where the guy that applied the cast stone didn't use any flashings between the veneer and the siding, where no kickouts were used, where no through-wall flashings or weeps were used over overhead doors and foundation vents, etc.. The walls were rotting on the front of the house and the clients stopped the inspection and walked. Yesterday, I inspected a very nice new custom-built house where the faux stone guy did exactly the same thing; hell, I dunno, maybe it's the same contractor who is still in business. Anyway, this guide has been included as an attachment to the report. It'll be interesting to see what this custom builder's response will be. ONE TEAM - ONE FIGHT!!!
