Is it just pure cement and water? Can you help. I read about these slurrys on the BR and cheng sites what are they? Can I make it at home?

Slurry can be just cement and

Slurry can be just cement and water but weve found there are many things you can do to help.

The main thing to improve your slurry is to use an acrylic modifier instead of water. This will help bond the slurry to your counter and have less shrinkage resulting in fewer applications. We use a product from Sika that we pick up at Home Depot. This is very similar to the tile industry that uses similar product for thin set mortar and grouts.

You can also reduce shrinkage by adding a filler. We've found microspheres work the best since there spherical. You could also use marble dust or try screeded sand but we find sand too angular and doesn't want to flow into the pin holes very well.

Other things you can use to improve slurry would be admixtures such as superplasticizers to increase flow and reduce water, Metakaolin to reduce efflorescence, accelerator to speed up processing time. And of course your pigment to color. All of these should be added in the same doses you would use in your main mix based upon your reactive material.

Hope this helps...

I agree...acrylic fortifier

I agree...acrylic fortifier and sandless grout or just portland cement.

Ive always just used 50/50 acrylic/water and straight cement.

Mixing ratio

Hi MC - I have heard that a fortifier and sandless grout works well for grouting a concrete floor that is to be polished.  I had a couple more specific questions, what would the mixing ratio be for the fortifier to sandless grout?  50-50?

 

Also, at what point do you apply it?  We are thinking of grouting the floor with the mix just before our 120 grit metal grind.
