Hi everyone,
I've never been busier with work than we are at the moment. Any free time I've had has been spent watching the World Series...so I haven't gotten the TLS review in for you yet.
I did take a bunch of photos with my phone, but the quality was terrible and I've deleted all of them.:mad2:
Here's a few thoughts about TLS to get us started:
What I don't like/what bugs me/minor issues:
1. Availability-there is only one retailer that I know of in my area that stocks TLS supplies. I've run short on straps and then had to race home in traffic to get the retailer before they close and get straps for the next days' work. I could buy them online, but always prefer to go local if I can.
2. The caps-the springs in the caps can either be defective from the factory or get worn out. What then happens is that the cap can be intially tightened securely, but then it will loosen within some number of minutes or even hours. This has caused problems because we missed this on various caps, and then the strap loosened and the
tile didn't stay tightly bound with the neighboring
tile, which then caused it to shift slightly. Our method is to now check multiple times the caps that we have tightened. When we find some that have loosened up, we tighten it again and if the cap is defective or worn out--we add another cap on top of the one already in place and tighten the two together.
As long as you catch all the ones that are loose, it's not a big deal and it doesn't take that much extra time. But it is a bit worrisome knowing that if something happens after the
tile is set, then you might be looking at cutting out a piece or two to reset them.
3. Placement of the caps and straps-as per the instructions of TLS, straps and caps need to be placed ~2" from the corners. I'm guessing that they think if the straps are placed any closer to the corner there is a risk of cracking the corner of the
tile when you break the straps out. For some stone, I'm sure this is a real concern. For some hard porcelains, probably not.
The placement of the straps and caps, in general, is a hassle because it forces us to change our usual habits of using levels and straight edges to check along grout joints. The thickness of the straps is 1/32", so if you want a grout joint thicker than that you must use spacers or wedges to hold the tiles apart. All of this stuff gets in the way and make the use of straight edges difficult.
We've had to adapt and and do more layout lines, and we now fire up one of the lasers to lay a line over the work to check for alignment. This takes time, especially when you have to get up, turn off the lights, turn on the laser, calibrate it, etc.
4. Keeping the joints clean-this is maybe the biggest PITA with the TLS. We use sponges, brushes, tuck pointer, margin trowels, pieces of cardboard, spacers, matches, shims and anything else that will do the job and try to meticulously keep the joints clean as we go.
Even with this effort, there is always thinset oozed in places that you can't get to, such as under the caps. We just used three Laticrete thinsets to set
tile (220, 253, and 254). The first two are fairly easy to clean out of joints. The third one (254) is like steel once it has cured and is a real :mad2: to try and clean up.
This "ooze-up" problem is important to remember when you choose the setting material for the job.
5. Added time to prep and use TLS materials-this might well NOT be a negative but simply a trade-off with time gained with faster production.
The straps need to be soaked prior to use. The instructions say it's a one-time only requirement, but we have noticed that the straps seem to behave better when we soak them before each installation.
It takes time to assemble the straps with caps.
It takes time to place the straps, tighten the caps, clean the thinset, break the straps and clean everything up and inspect and put the caps away.
6. When you come to a point where you are stopping for the day, it is imperative that you CAREFULLY prepare small voids under the tiles so there will be spaces to slide straps in the next day. Alternatively, you can set straps under the last tiles and make sure they aren't sitting in such a way as the prevent the tiles on the next day from sitting in place properly (ask me how I know of these problems :incazzato: ).
It's important to ensure that there is thinset around the strap's base, even if this means adding some mortar directly in place with a margin trowel. This takes more time, and it's a bit more difficult to get the notched trowel to spread thinset in and around all the caps and straps that have been placed in position on surrounding tiles.
7. "Whoops"-If you over tighten a strap, it will break. If this strap is in the field of
tile that is already set, then you have to either do without a strap or pull the
tile up to get another strap in place. (Ask me how I know about this. :mad2: )
How will you know if you are overtightening a strap? Easy--it breaks. :lol: But with experience and getting used to the gun and the feel of the straps, you'll avoid accidental breakages after you use TLS for a while.
8. The "salespitch"-TLS has changed their marketing somewhat since they debuted ~3 years ago.
TLS
will not:
1. serve as a remedy for bad substrates
2. compensate for a
tile setter that doesn't knows what he is doing
3. fix tiles that are warped (ie: not flat)
By now, this sounds really negative...but wait until I talk about some of the positives. All-in-all, I like using TLS and will continue to do so. I'll have more later.
Dinner is ready. :smilewinkgrin:
