Concrete Countertop Slurry Mix

Product Detail:

Concrete Slurry Mix for filling in any imperfection or holes in concrete surfaces.

Contains a blend of Portland Cements, Cenospheres, and Pozzolan. Cenospheres act as miniature ball bearings, allowing the slurry to fill small pinholes easier, and act as a bonding surface for the cements to reduce shrinkage and cracking of the slurry.

Just add water. For a stronger slurry and better bonding, replace water with a water mixture consisting of 1 part Polyplex to 5 parts water.

Slurry mix can be pigmented before application, or stained once applied and cured.

Product Specifications:

Size: 64 oz. (2 quart) container. 3.4 lbs. by weight.

Color: Natural cement grey.

Coverage: Coverage rates vary depending upon size and number of voids to be filled. 64 oz. of slurry will usually cover around 100 sq. ft. of concrete surface with minimal pinholes and voids that need to be filled.

Contains Portland Cements, Cenospheres, and Pozzolan.

Application:

Preperation: Polish, grind, or sand the concrete surface to open any voids in the concrete that may have just a super thin covering of cement over them. Wet concrete surface before applying the slurry, but do not over do it. Just keep the concrete damp as you work- no standing water.

Coloring: If coloring the slurry, mix the color into the slurry in the same ratio as was used on the concrete mix.

Mix: Put a small amount of Slurry Mix into a mixing container, and add small amounts of water until the mixture looks like peanut butter. Optional: For a stronger slurry, and better bonding, consider using a mixture of 1 part Polyplex to 5 parts water instead of just straight water. If a superplasticizer/water reducer (such as SP-7000) was used in your concrete mix, you may also want to add a tiny amount of this to your mix water.

Apply: Using a putty knife or your fingers (use Rubber Slurry Gloves) on uneven surfaces and edges, work the slurry into the concrete. Use a spray bottle with just water in it, and keep the concrete damp before you work the slurry into it. Usually working the slurry in one direction with a putty knife, and then pulling across the same area in a different direction will ensure the best fill. On large voids, the slurry should be left a little thicker, as it will shrink down as it dries.

Finishing: Allow slurry to dry at least a few hours before attempting to sand. Usually using 200 grit sandpaper by hand, or on a palm sander, will work well. If wet polishing, allow the slurry to dry a few days first. Once sanded, determine if another slurry coat is needed. Multiple coats of slurry are often necessary to obtain a completely flat concrete surface.

Staining and Sealing: Slurry should be allowed to dry at least 24-48 hours before staining or sealing. Most stains react to the cement in concrete, so areas of high cement content, such as a hole filled with slurry, will generally stain darker than concrete around it that usually have a lesser cement ratio. With all color and staining, doing a test batch or area is recommended.
