Today we talk about 3 reasons why your polymeric sand may be loose on a project. This is usually due to installation or environmental reasons for why it is loose. It could be that the installation instructions were not followed properly, it rained after installation, the project is in a shaded area, or improper base material was used.

"Why is my polymeric sand failing?" Because polymeric sand is garbage. If have joints greater than 1/8 in, use Easy Joint and you'll never look back. If you have joints under that, watch this. Great video, informative as always. I'd love to see you do a breakdown of a laser versus an altimeter (U-level) on a site. We've been using u-level for years and are wondering if we should switch to a laser, don't really think that's the case, but would love to see a comparison on a build.

Yes it does seem like the industry sentiment is slowly moving towards those semi-permeable jointing compounds. Appreciate the suggestion! Will definitely cover that this year at some point 👍👍

I just regrouted my patio a month ago. It felt like it hardened just fine but we got rain last night and all my polymer sand is wet, it reactivated. I'm at the end of my rope. Is this easy joint bette? Will it actually stay hard?

@PuppyStomper87 8 дней назад

@@silverrush1411 We absolutely love the product, and it does harden to grout like texture. We've used it in all of patio applications except one, and it's fantastic. Super easy to use, legions less restrictive than polymeric - add water, fill the joints, no worry clean-ups. There are a couple things to keep in mind: if your patio is a state of failure, the EasyJoint will fail (think of it as if you had tile grout, and pulled the tiles apart - what would happen to the grout?); it does not work well with tight (narrow) joints. I'd say 1/8" or greater. There are similar product to EasyJoint that is supposed to work with tight joints, but we haven't used them yet so I can't speak to them.

@PuppyStomper87 my paver patio is only 5 years old and the joints are over 1/8 ". I just don't understand how the grout could reactivate and wash out. I folled the directions and made sure not to over or under water. It started to repel water so once it did that I moved. I removed all my old grout that was done by contractor due to the same thing and moss growth. What are the cons to this?

@haydeneverett1990 3 месяца назад

Have you ever gotten a job to pressure wash and re-sand? I feel like at that point it’s always lift and relay or a full redo.

@iamahardscaper 3 месяца назад

Yes, I used to do them when I was first starting out. Only if it is just a sand problem. If it is a weed problem, its almost always a full lift and re-lay. I learned that lesson.

@g2gCthe 3 месяца назад

question for poly sand, is it require to use plate compactor or can i use a manual steel tamper?

@iamahardscaper 3 месяца назад

It’s best to use a plate compactor for the vibratory compaction and not a ramming action. In a pinch, guys have used a hand tamper. Just make sure you have something to protect the pavers

@professormeow7432 3 месяца назад

I just finished applying polymeric sand to my paver patio while it was still damp…. Now I seem to have some stains on the stone pavers. How do I remove the stains??

@iamahardscaper 3 месяца назад

I would start with a hot water pressure washing. If that does not take care of the staining, you would have to then wash with a polymeric sand haze cleaner.

@micheal4487 3 месяца назад

Hey when you use 3/4 gravel as a base do you use 3/8 1” bedding base? Most importantly what I was concerned about if you use open grade base and bedding does polymeric sand just keep falling into that base when you’re sweeping it in and compacting?

@iamahardscaper 3 месяца назад

yes, always use the 3/8 or 1/4 chip on the 3/4" base. I find that there is about 10% more use of polymeric sand in these applications, but it does not just keep falling into the base the gaps are just not large enough. Some people use non-woven geotextile in between the base and the bedding layer. I do not

@micheal4487 3 месяца назад

@@iamahardscaper ok thanks, I’ve been wanting to switch but been concerned about that.

I have limestone patio tiles where the polymeric has washed out over the years. The contractor replaced that failed poly with torpedo sand and my wife hates the color difference between the lighter almost white limestone and the brown/beige torpedo sand. It appears that most suppliers near us only have torpedo and masons sand that is beige. I’d prefer not to do polymeric again. Is there any alternative that is closer in color to limestone that I could use as a sweep in into the joints? I realize any sand without binders like polymeric will wash out and need more frequent replenishing. Thanks for any response. Love your channel!

@iamahardscaper Месяц назад

Ohh that is tough. You may be looking into a polymer modified grout. Ardex has a lot of colors available. But I don’t like using it unless they are laid on a concrete base.

@Bluebirdjunction Месяц назад

Wow, I can’t believe how fast you replied! Thank you! And yes it’s a tough spot when you don’t have a happy wife. The local hardscape supplier suggested that rather than masons sand to use finer limestone screenings but I recall your video saying that you should not use limestone screening although that was for base application. Does that critique apply to jointing as well ? I don’t expect to have much depth need as the torpedo sand is pretty well impacted in the joints. This would be maybe a 1/4 on top to get the color that the wife would approve. Thx again for any insight!!!

@iamahardscaper Месяц назад

That may be something you want to use. I personally wouldn't because I prefer something in there that will bind itself to the stones. But I also would not use torpedo sand because of this. I'd say get a handful of it from the stone yard, bring it back home, see what she thinks, then proceed. you could even do a little portion of the project to see the results first.

Thanks so much!!!
