Concrete mix with no sand?

[proton]

Is something like Quikrete available here where you just add water to mix it? It's only a large crack in the patio that needs filling, rather not bother with bags of sand as it does not need to be that strong

Homepro carry saveral Ferro products such as:

I've used this one to make outdoor light pedestals and its perfect. Already contains sand and cement, just add water.

Just the job thanks

Look for a concrete yard on the edge of town.

One selling pipes and cinderblocks.

They should have a variety of bagged concrete mixes, some just add water.

use hot water for a rapid set

I'm thinking you need a cement mix, not concrete. Concrete has a gravel aggregate mixed into cement to add structural strength. as you are only wanting to patch a crack , you need some thing that is more flexible.. Cement mix is a sand and motar mix. To make the mix a little more workable when applying, squirt a little dish washing liquid into the mix.. Its more like a thin putty then.

 

[The Theory]

How wide and long is the crack ? If does not need any cement just use ready wall patch.

Hijacking the thread.....soz.....what do people use to fix 'hollow' tiles?

 

Just had the local village idiot do about 90 sq m and half are hollow sounding.

I would be interested in answers to this also. I have a couple of hollow tiles and was thinking i will have to remove them and replace with new tiles, only this time apply the adhesive to the whole area under the tile.

We had some fixed by the original builder, but I didn't pay much attention.

 

I think he drilled into the grouting and then just squeezed in what I suspect was a very sloppy cement/water mixture from a washing-up liquid bottle.....worked well.

That is the only way unfortunately, and its quite difficult to achive good results if its a tile surrounded by others as there is no way for any excess mortar to be squeezed out

Thinking back....I have a feeling he scraped a section of the grouting out...not drilled???

 worth a try but its not guaranteed to work if the void is surrounded by hardened mortar

Yes...of course.....I was assuming (stupidly) that the void would be up to the edges.

[Bday Prang]

The op could consider buying a small bag of premixed tile adhesive  it contains sand , cement and some sort of glue , just add water its commonly called "poon gao"  and crocodile is one of the popular brands less than 300 baht a bag last time I bought some

You are unlucky to have had problems , most Thai builders are pretty good tilers

The couple who did the inside tiling ran away at the end of the job????.....the builder had to pay for...I would guess, 6 man days, to correct their work.

 

We then employed another local 'builder' to tile 1000 sq ft outside.......and he was worse than the couple who ran away.

 

Of course I was not allowed to say a word as he was a local.

Bad luck indeed, and I fully understand your frustration regarding the inability to criticise. I tend to do as much as I can myself, and only hire in assistance when absolutely necessary.  The need to walk around as if on eggshells for fear of hurting somebody's feelings is very difficult for me to accept, especially regarding sub-standard workmanship.  

A Thai or god forbid a chinese Thai,  employing a builder would not exercise any  such restraint. it seems to be a peculiar trait common to the wives of farangs

Yes indeed......... wives of farangs...........I guess they know what retribution might be wrought for a farang stupid enough to "have a go". Plus it can leave them in an awkward position  if a dispute arises.

Yes, in HomePro and Global House or like stores, for example Best Bond Repair Mortar. The moderns times you don't add water but the enclosed liquid only, as it's a "two-component" A-B mix. The same type of mix is now also used for high quality tile grout. It actually works very well...????

5 metres and about inch deep, caused by previous 'builders' not using re bar and inferior hard core. If it looks too bad when done will cover it up with artificial grass, not worth having it all torn up and done again

Fill it by spray foam and cut extras that pop out and then paint it. It will look good .

Did that before, it was far too soft, ripped it out the other day.

You can't, they sound hollow as there is no mortar bed completely covering the underside. They can Crack very easily. Only correct way is to pull them and replace them

If the crack is not very wide you can use a caulk made for concrete. It's flexible and has the texture of sand and Grey color. If the crack is wider than 1/4 " they make a backer bead made from foam like a rope. Stuff that down into the crack and them the caulk has something to press against as you caulk the crack. You need something flexible or if you patch it with mortar mix it will just crack again

that is an incorrect answer. Certainly some will be unfixable, however there are thin, virtually as thin as cream compounds that are inserted with a syringe that will fill all the voids. The possible problem with these are that they are anything but cheap so pulling out and replacing may be preferable.
