Long Island, NY. May 2, 2010. #1. Our paving stone pool deck and patio is nearing completion but the joints have not been filled yet. A neighbor recommended that I talk to the contractor about using polymeric sand. He said that using polymeric sand will result in a much more stable patio and will stop weeds from growing in the joints.
20x40 Inground Poo, vinyl liner Just had new work done around the pool they used polymeric sand which trickled down the wall of the pool and accumulated where the wall and the bottom meet. Now I have been able to vacuum most of the bottom clean, where the polymeric sand has accumulated, I can't...
One thing to keep in mind with polymeric sand is that there needs to be a minimum grout space of at least 1/4". Even that is quite small. If there isn't adequate gap, polymeric sand will not set and people walking on it and rain and wind and everything else will just spread it all over the place and it will never harden. It will become a big mess.
Thanks for this. Yes I mean polymeric sand in general and not a specific product. I was concerned with how well it would hold up in the joints. I wasn’t even thinking about the face of the bricks. Heres a pic of the front walk. I don’t know for sure its original to the house (built 1912 we think) but it’s likely.
The guys installing our pavers got a bunch of activated polymeric sand in the pool on top of the gunite. It's stuck there pretty good at this point. The mini pebble tec was supposed to be put on next week. Does anyone know if the stuck on polymeric sand will cause a major problem with the...
Mar 4, 2016. 205. McKinney, TX. Aug 2, 2017. #2. I'm curious about this too. Our travertine paver decking does not have mastic between it and the coping, just the polymeric sand that they use between the pavers. The builder said they do the mastic with concrete deck not pavers. It seems fine but now wondering if mastic should have been used.
It does appear you need another application of poly sand (hopefully this is what they used). That will help with the grass growing. Did you just do some re-seeding? It could just be a few seeds that caught just right in the pavers but typically you should not have grass growing in a properly installed patio using polymeric sand.
But if you do decide to replace the sand, it should simply be a matter of getting the old stuff out, inspecting/cleaning the interior, laterals, and stand-pipes, then carefully refilling with the new sand as required. If the entire multiport valve(s) must be changed, it certainly can be a DIY project. $5,300 seems like a lot of $$$ to me.
I poured sand onto the sealing compound after I finished a 10' stretch. I don't know if that is a good idea or not, but my previous installer did this and it gives a nice finish. Again, may not be worth the $5 for a bag of sand and the effort. VERY IMPORTANT! Do not let the compound set up before you remove the tape.
