This handy how-to guide will walk you through the basic steps of making concrete countertops!
DIY Concrete Countertops | Covering an Existing Surface
The simplest way to DIY concrete countertops is by using the countertop you already have as the base. This method works very well over Formica, a solid surface product, or even tile.
Important Note: For best results, remove drop-in sinks, faucets, and cooktops before you begin.
Step 1: Prepare the Surface for the Concrete Countertop Mix
Using an orbital sander or a palm sander, scuff up the surface of the old countertop. If the countertop is too smooth or shiny, the concrete countertop mix will not adhere properly. Take your time, and be sure to sand everywhere. Don’t forget the sides and edges. Run your hand over the surface, and with the sander, knock down any smooth places that remain.
Step 2: Protect the Surrounding Surfaces
To keep the concrete mix off of the surrounding surfaces, be sure to cover the cabinets, floor, and backsplash with plastic sheeting.
Step 3: Prepare and Apply the Concrete Countertop Mix
There are many concrete countertop formulas on the market that float well over an existing countertop. Two popular brands are Ardex and Henry’s. While it’s possible to make your own from a regular bag of basic concrete mix, we recommend using products specifically designed for skim-coating for two reasons. First, you’ll have less waste since these products are available in smaller packages (leftover dry concrete mix does not keep well). Second, all of the large particles and gravel are filtered out of these formulas which is critical for skim coating.
Prepare the concrete according to the package directions and apply a thin first layer with a putty knife.
