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.
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. | |||||||||
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 for the quick response. Is the acrylic fortifier taking place of water or is it in addition?
It should be ok but I don't think it has as high a solids content so you may dilute with less 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.
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.
