Question
The stones outside my screen enclosure have crushed granite between the stones. This keeps washing away in the rain and I am left with mud between the stones. I saw an episode on HGTV where crushed granite was mixed with Quikrete concrete mix swept into the gaps between the stones, watered and the crushed granite and concrete hardened to create a form of "grout". What I missed was the portion or mix. Would this work to solve my problem of the granite washing away and what would the formula be? Thanks so much

Hello, Rockie ?I searched the HGTV websites (HGTV.com & DIY.com), but didn抰 find the program you were referring to on either.  I had not heard of mixing quickrete with the crushed rock to create a 損ermanent?joint.  It should work though, IF you have the correct proportions.  I would think that it may cause a bit of discoloration if not applied correctly, as the lime dust may "bond" to the actual paver surface, graying the color down in the process.

I have heard of polymer products that you can mix into the sand (or as a direct substitute for the sand), that achieves the same thing - No erosion of the mortared joints.

The definitive source on 揳ll things pavers?is the Interlocking Concrete Pavement Institute's website, ICPI.com   They have a homeowner抯 section for general installation - no mention of the quickrete method.  

If you are looking for the polymer material, I mentioned, you can go to their on-line magazine (or you can subscribe, and they抣l send you one every month!) and peruse the ads.  I'll save you some time. Here are 6 manufacturers of this polymer joint-stabilizing material I'm refering to:

Polysweep, found at sek.us.com
Super Sand, at supersandbond.com
Gator Dust, found at gatordustbond.com
For a 揼reen?method, Envirobond, at envirobond.com
Techniseal, at techniseal.com
Surebond joint stabilizer, at surebond.com

I think, from what you抳e described, you'll want the 揼ator dust?as it is designed for larger gaps in pavers. If you want to 揼o cheap?using quickrete & stone dust, then you抣l have to search yourself at HGTV.com, as I came up empty.  I'd use caution if you do go that route, because of the "discoloration" potential I mentioned - if the pavers are already "gray" colored, maybe not so much an issue.  

Hope the other info helps.
