Can I use self-leveling concrete for countertops?
In addition to flooring, self-leveling concrete is popular for concrete countertops. The product is highly fluid and pourable, reducing installation time frames. The end result is a concrete countertop with strength and low permeability. It is compatible with limestone aggregates.
How do you fix uneven concrete countertops?
There are several ways to repair rough/uneven surfaces. The first and most common method is to grind and polish using a wet polisher and diamond polishing pads (and possibly a diamond cup wheel, depending on the severity of the imperfections). You would begin with the lowest grit necessary and work your way up.
Is self leveling cement strong?
It is obvious that the strength which is required for a floor is different if you are in a warehouse, a grocery shop, an office or a house. To follow this need, every self-leveler reaches a specific compressive strength. Today, you can find self-levelers going from 3,000 psi to more than 7,500 psi.
Can you pour concrete countertops on plywood?
If they are cast in place, then the answer is yes. The plywood for cast in place concrete countertops is a permanent portion of the formwork. The plywood simply serves only as a form bottom, to keep concrete out of the cabinets, and it ceases being necessary once the concrete cures.
What type of concrete is used for countertops?

How thick can self leveling cement be?
QUIKRETE® Self-Leveling Floor Resurfacer (No. 1249-50) can be installed from 5/8 inch (16 mm) thick to a feather edge. For areas deeper than 5/8 inch (16 mm), apply QUIKRETE® Self-Leveling Floor Resurfacer (No. 1249-50) in layers no greater than 5/8 inch (16 mm) each.
Do you need primer for self leveling cement?
Self-leveling underlayments require the use of a primer prior to installation (like the TEC Multipurpose Primer). Failure to use product recommended primer may result in installation failure. Primer retains the moisture within the self-leveling underlayment to allow proper curing.
How thick should I pour a concrete countertop?
