Slaking grout

jyang949 | Posted in General Discussion on August 19, 2008 10:14am

Is it necessary to let grout slake in the mixing container? It would be easier to push the grout into crevices before it thickens, and allow more time to work. Wouldn’t the grout slake anyway, once it’s between the tiles?

I’m wondering if there’s a chemical or structural reason to slake before applying the grout.

    grout is a mixture of binders, pigments and solids to perform properly ALL the ingrediants must be "Wetted" by the water.

    some of the ingredients absorb the water slower than others, Slaking allows them to "catch up"so they can react appropriately.

    also the water will soak into any clumps and assure that they are mixed more homogeneously (hope that doesn't get the ###)

    It may help with air bubbles too. If the directions on the bag tell you to slake, then you'd better do so. Mix it just a little bit wet if it gets too thick on you.

    1. Piffin | Aug 20, 2008 02:21am | #6

      be carefull with that "little bit wet"That can make it easier to work, but most failures come from too wet.

    The instructions say so, right?

    I've never been one for just plain going by the book either without understanding why...

    So you need to see the process on a microscopic scale.

    The goodness of cementious products like this is dependent on both a chemical reaction and a mechanical one.

    Essentially the primary ingredients are the parts of microscopic sea animals from long ago. They are shaped much like small suction cups.
    Then you need to remember how surface tension of water works. Spill a couple drops on a glass surface and see how it beads up? It takes a little mechanical action for it to spread out over the surface.

    That is what is going on with mixing, then slaking off, then mixing again - you are letting the surface tension of the water break down and fill the cups of the little old seashells so there is no air interfering with proper adhesion that will hold the powder together for a lifetime.
    If you work it too quick and you have failures such as shrinkage cracks or flaking.

    if U have to ask ...

    U obviously haven't laid enough tile.

     

    or have laid the tile U have laid ... ? ....

    not fast enough.

     

     

    'cause ... if U had laid enough ... or enough fast ...

    You'd not even question the slaking.

     

    the slake ... is a wonderful time.

    it's a time to chug a bottle of cold water ...

    a time to hit the portapotty ...

    a time to wander around the job site and annoy all the other trades who aren't forced to "slake off" on a hot summer day ...

     

     

    slaking is time to stretch the knees and clear the mind ...

    zen kinda stuff ...

     

    before getting back to the hard work of laying tile.

     

    slaking is a natures way of saying ...

    hey kid ... relax for a minute ... or 10 to 15.

     

    there's plenty of hard work to do ...

    no need to rush into it all at once.

     

     

    only reason I tile is to slake.

    take that away ....

     

    and it's too much like roofing!

      You don't let your shingles slake? Maybe that's why it take me so ong to shingle a roof.

      'To slake, or not to slake: That is the question.

      Whether 'tis nobler to suffer the shame and call backs from improper grouting,Or take the time to properly slake as per the directions.

          Don't have a bag of grout to look at, but here in NW Oh I have always used the long A pronunciation.

          How is it spelled on the grout bag?

          slack

          slake?

          Don't know if grout succumbs to roberts rules of order or the marcus of canterbury's rules but "ake" is usually long A.A Great Place for Information, Comraderie, and a Sucker Punch.

            OK, I knew I had a carton of grout or two on the shelf over there, so I went to look and see how they spelled it.My grout was black BTW, so you can imagine how my keyboard and face looks now, having gotten residue on my fingertips while rotating the carton looking for the english version of the instructions....So after all that, and getting my eyeballs narrowed down to the fine print focus...The way they spell it is s-i-t as in "...allow the mix to sit for ten minutes..."LOL
