What is the benefit of using the organic sand stabilizer over a polymeric?

Most people believe that joiunt sand stabilizers are basically all the same. Not True.... There are a few Big differences:
1- SandLock is able to be applied much easier without fear of washing out the binding properties. If you look at any polymeric website, you'll see that the activation process requires numerous light mistings to fully activate the joints. You also need to wait 5-10 minutes in between mistings. Huge waste of labor hours! If by any chance you put too much water at one time, the acrylic beads (in ALL polymeric sands) will flow to the top of the joint and wash away. At that point, you would have no more benefit than regular sand in between your joints. With SandLock, you are able to fully SATURATE the pavement at one time. Big time saver!!

2- The most important aspect of ANY stabilizer is the ability to repair itself over and over. Polymeric stabilizers have a lifespan of 3-5 years..and that is if you activated the joints properly (not easy) SandLock's binder properties have been around for almost 20 years, and have yet to lose its' binding characteristics. When joints dry up, they will crack. The job of the stabilizer, is to continue to effectively repair itself time after time.

All I can say, is give SandLock a try. I myself have done numerous tests, comparing polymeric sands to SandLOCK. I can honestly say that the difference isn't even close.

Got to go, the Hardscape of North America Trade Show is soon to begin!

Another great thing about organic joint sand stabilizers is they are environmentally friendly and safe for plants, animals and people.

Polymers do not harm the environment. No plant, animal or person was ever harmed by use of a polymeric sand.

Is there any problem with sealing over an organic sand with a solvent acryilic sealer?

Someone said the lifespan of polymeric sand is 3-5 years. Is that what everyone else is finding?
How about for organic sand, what is the lifespan. I know 20 years was mentioned but manufacturers of polymeric sand will say 10 years, thats how long we've been testing the original sample for. Any real life time frames not from ideal lab conditions?

Does anyody blow out old sand and install organic or "Sandloc"

Thanks for the info!

Any organic material needs to breathe, so using any type of solvent acrylic sealer will prevent that. But, if you are using an acrylic sealer, there is NO reason to use any stabilizer, organic or polymeric, as the acrylic sealer will provide excellent joint stabilization along with great protection to the surface. Yes, polymeric sands are lucky to last 3 years...especially if you mess up at all during installation. The fact that you have to mist polymers numerous times, in order to activate the entire joint and not wash the binder out is ridiculous. With sandlock, you only have to 'saturate' the pavement thouroughly ONCE, and you're done. Pave tech says they don't have a lifespan yet, because the binding characteristics have yet to fail in almost 20 years..??..

If the pavement has poor drainage (water sits on the surface for a long time keeping the joints wet) it will shorten the life of both poly and organic stabilizers.

Thanks for responding. Any body have thoughts or opinions on joint stabilizers liek Surebonds 1300 or Techniseals JS?
