Your on the right track.  Basically your simply slurring or grouting the voids.  Since your not going to see it a topping mix would work or make your own...

The acrylic polymer is the key for adhesion and curing.

Thanks for the quick response. Is the acrylic fortifier taking place of water or is it in addition?

	Grout / Slurry mix
		Weight Grams
	Cement	800	Total 1000 grams cementitious.  Can be just Portland
	CSA	200
	Microspheres Sm(.1-.3mm)	200	bulk filler/ shrinkage reducer/acts like ball bearing filling in pin holes
	Pigment (optional)	%	Is usually the same % as main mix
	Acrylic Slurry Liquid Admix		can be made using 1 part KongKrete Liquid polymer and 4-5 parts water
	mix to desired consistancy.
	Dry ingredients(you can mix up as much dry and store in buckets until ready to use)
	Wet ingredients(Mix up as much as you want and store in sealed container until ready to use)
	Lightly dampen surface then mix slurry into a peanut butter consistency using polymer and water solution then spread into voids. Make sure the slurry is packed into the entire void using hand, grout float, sponge or whatever works.

And is the sika concrete bonding adhesive and acrylic fortifier ok. What ratio should be mixed?

Anthony...I put our slurry mix below.  The acrylic is in addition.  We use one part Kong Polymer (50% polymer solids) to 4-5 parts water.

Thanks so much Tom. Is that Sika brand bonding adhesive and fortifier ok to use? It's what I was able to find locally.

It should be ok but I don't think it has as high a solids content so you may dilute with less water....

Hi Anthony,

I believe the Sika fortifier is about 12% solids.  To get the same amount of solids using Sika, using Tom's ratio of 5:1 or 6:1 water to Kong Krete, you would use 2 parts Sika, 1 part water.  

I've used the Sika for a slurry and it works, but when you look at economics the Kong Krete is a better product.  It takes over 4 gallons of the Sika to get the same amount of solids as in one gallon of Kong Krete.  So to equal the 5 gallons of Kong Krete at $125, you'd need to buy 21 gallons of Sika.  At $12 each, that is about $250 + tax.  Even with the cost of shipping Kong Krete, the Sika ends up costing you more.  It seems cheap at first because you can grab a bottle at home depot, but in the long run you end up paying way more for the Sika.
