A thin bed adhesive tile adhesive with a 'porcelain' formula is the way to go LOL. Reminds me when a team of "tilers" started at my house to lay the 60x60 tiles. They laid a bed of mixed sand and cement, wetted it, and laid the tile. When I asked them if they were not gonna apply glue, they looked at me as if they saw a man from Mars. So I explained them and then they applied. At the end of the first day I looked at the tiles they had laid, and asked them to remove all and redo, as they were not in a straight line. Same happened the next day, after which they came to pick up their stuff during the evening when I wasn't there, to never be seen again. I was already suspicious that they had all new tools when they arrived, turned out that until 2 days before they were actually window fitters, but had run out of a job Edited December 6, 2020 by Susco 1 Link to comment Share on other sites More sharing options...
Elkski Posted December 6, 2020 Share Posted December 6, 2020 (edited) There are many ways to lay tile. Some old school and some modern. It is best to use a good quality thinset. If the substrate doesn't flex and good thinset, of the proper type, the tile should never separate. 1st thing to check is subfloor flexing. Here in US we use mostly wood beams and subfloor. First thing to do is calculate the beam deflection. It should not exceed L/360 deflection. For porcelain tile. Stone needs stiffer. Natural stone is less porous and harder for mortar to stick to. Also cracks easier. https://www.tcnatile.com/faqs/30-deflection.html I have only seen crazy tile methods in Thailand and Vietnam. I love to observe building projects when I can. In Vietnam I watched a living area dining room house tile job . It was crazy. It was 4 women and 3 men to do the dry bed. The women did most of the real hard work. First they did have real survey marks in a few locations and used a water level amd caulk line to mark the perimeter of the room. The boss poured lots of powder termite killer around the outside border. This was a slab floor poured on sand fill of 1 meter depth. No compactor. They did walk on it and hand tamp it and used lots of water. I sunk in 30 cm. It was a bit harder the next morning when they stsrtedctying rebar. And Poured cement the next day. Thwy did have a day where they poured cement beams for window and door headers for the front door and windows . After the termite powder thrown, poured unevenly around perimeter the women made a big pile of sand in each room. Then they poured on 2-3 bags cement and a bit of water and all started mixing. It did have a good dry mortar consistency but I could see the cement wasn't mixed in very evenly. Then they started to toss it to one corner and side. Boss and worker screed it to the line and moved it around with hand trowels. It was proper dry bed thickness of about 3-4 cm thick.. The women were very good at tossing shovel fulls where needed. I have done mud beds . They proceeded across the room and checking with the scree board in all directions. Then they did the adjoining room. Rooms were joined by like 4-5 meter opening. Most people wait till next day to tile. But they started laying tiles right after lunch. I recall larger tiles maybe 40x40cm. They mixed up a cement slurry. I actually don't know what was in the bag since I couldn't read it. But it seemed like the same grey cement they always used. They mixed it to near water. Not even as thick as syrup. They pored a thin layer on the floor and laid the tile down. They did use a hammer on some tiles. They did have trouble where the rooms joined. It was like the dry pack was still soft enough to move with the hammer. They basically had no grout line and no spacers. I forgot to look to see if the tiles had alignment lobes. Right after they laid the first room and were on the way in the remaining area. Everyone got to grouting. It was non sanded grout . It was in different smaller bags. They poured it in dry. Using cardboard and things to get most along the lines. Then they dripped water on the lines. I was shocked. After pushing excess towards the crack they then mixed up a slurry or added more dry powder to fill the cracks. They left an excess amount on the tile maybe 4-5 cm wide 1-2mm thick. I saw in kitchen that had been done the week before that the grout was the same and had not been cleaned off yet. Not sure how they cleaned off the grout. I can't believe this tile will last.

I guess you haven’t seen that many tiles laid here. Tile adhesive is often not used. They are very commonly laid on a thick bed of sand (several cm thick) with a modicum of cement added. Certainly a percentage are laid using thinset. Link to comment Share on other sites More sharing options...

A thin bed adhesive tile adhesive with a 'porcelain' formula is the way to go, the only way to fix a loose tile is to remove the grout and take the tile up, remove 5mm or so of sand/cement bed, then stick the tile or a replacement down with the thin bed adhesive as above, that's my 2 cents worth after 40+ years as a ceramic wall and floor tiler While I have seen them use cement, most of the setters I've seen use thin-set. I like the Crocodile in the green bag, it's pretty cheap and it works great. Link to comment Share on other sites More sharing options...

Yeah, sorry I was talking about cutting tile and concrete. What kind of wheel do you use? I can't find one thin enough. The grout remover scrapers work pretty good but they take a bit of work...

No problem, and to be honest I have never cut into grout with a grinder, I was just suggesting to the other poster to have the wife or someone else hold a vacuum cleaner there when cutting, the reason being is, when I have drilled holes into walls in the past, I have the Mrs stand there with the vacuum cleaner hose to catch the dust.

I tried the grinder on grout once, takes a lot more control than I have. Once you get it going it's not too bad, but one little slip and the tile is dicked up. Bought a Makita multi-tool (vibrating-cutter/saw) and tried that but it was a pretty good PITA as well, although damaging the tile was not really an issue with it. For my money the grout-scrapers work pretty well, particularly if the grout is in bad shape. 1 Link to comment Share on other sites More sharing options...
impulse Posted December 6, 2020 Share Posted December 6, 2020 Word of caution. There's epoxy resin available on Lazada in 1/2 liter cans. It is way too thick (viscous) for what you're planning to do. The price is right, but it's not good for any projects where you need the epoxy to flow. Suck it up and pay for marine epoxy if you're in Thailand. Here in the USA, I buy tabletop epoxy on Amazon for around $50 (USD) per gallon. Maybe they can ship to Thailand? Link to comment Share on other sites More sharing options...

Wish i just bought it at the local marine supply store. If the lazada product is too thick, can I buy epoxy at the boat builders and use the hardener from lazada? IIRC the epoxy is cheap but the hardener is v expensive? Link to comment Share on other sites More sharing options...

A few years back when I bought mine they only had one type that showed up under a search for "epoxy". In red and yellow and black cans. Very viscous. In fact, too viscous for my boating related project. Glad to hear the selection has improved over the years.

I've seen some crazy things in LOS. My Thai BIL made an outside bathroom, but the sink wasn't draining. I dug up the outlet pipe and found it stopped before it got to the drain. He also omitted to put a pipe through the wall before he tiled it for the toilet water tank. Making a hole in tile is really difficult without a proper tool, which I could not find, and had to use masonry bits. In the end I had to replace the entire tile.

Since nail polish remover is often 60% acetone and the pure version is much cheaper, though not so good for cuticles and skin, that’s not surprising.

TopDeadSenter Posted December 14, 2020 Author Share Posted December 14, 2020 Update on repairing loose floor tiles without removing. 1)these tiles were virtually undrillable, not sure what material, went through 2 bits so 290B per hole and that was using copious amounts of H2O and not drilling for more than 5 seconds at lowish RPM in one go. Took an hour per hole. 2)epoxy ordered from lazada, lovely stuff clear and nice flow. 3)tested by blowing air with a straw through the hole in tile - sealed with some dinnamman- to make sure it was all hollow underneath and ready to pour resin, but there was no space under tile, couldn't suck or blow any air at all, both holes the same, so gave up and painted balcony wooden furniture with the epoxy - looks great! Steve the professional was right. Do it the proper way. Link to comment Share on other sites More sharing options...
JeffersLos Posted January 20 Share Posted January 20 A few floor tiles have become squeaky over the years, some of them have a corner that will move up and down a millimeter or so when pushed. The spacing is around 1mm. The grouting has some gaps etc at this stage. https://www.lazada.co.th/products/50-1000ml-i4963780323-s20913537552.html? Has anyone used a product such as this to stop the movement and sqeaking? Link to comment Share on other sites More sharing options...

Will B Good Posted January 20 Share Posted January 20 Haven't read the thread!!.....but our guy put a tiny drill hole into the grouting and then squirted in a very watery cement mix......worked like a dream.....about 40 plus tiles had to be done..... 1 Link to comment Share on other sites More sharing options...

Yellowtail Posted January 20 Share Posted January 20 Acetone will not dissolve polypropylene. Acetone will dissolve polycarbonate. Most syringes are polypropylene and will work fine. Syringes that are polycarbonate will not work. It is pretty easy to tell the difference between the two. Link to comment Share on other sites More sharing options...
Yellowtail Posted January 20 Share Posted January 20 Incidentally, you can buy acetone in polypropylene jugs. Link to comment Share on other sites More sharing options...
