How To Paint Tile Backsplash in 6 Easy Steps

Before starting your project, clear your countertops of everything possible and cover the horizontal surfaces with painter's tape, plastic, or a drop cloth. 

Check the condition of your existing caulk between the backsplash and the countertop. If it's cracked or peeling, use a putty knife to remove damaged sections. 

Finally, remove any outlet covers and apply painter's tape over the outlets. Be extra cautious when performing this step and when painting near the outlets later, as the live electrical is exposed. 

There's no shame in turning off the electricity to the kitchen circuits at the breaker panel if you feel uncomfortable working with the outlet covers off.

While you don't have to follow the precise steps for cleaning tile and grout when painting your tile backsplash, it's essential to do a thorough job of it. Put on your protective rubber or latex gloves. Use a degreaser solution to remove any built-up grime. Phosphate-free TSP also works well for this purpose. Pay particular attention to places where you'll need to repair the grout after removing it earlier. Use rags or a sponge to rinse the surface.

While you can repair cracked tiles with epoxy, when the plan is to cover them with paint, you can perform an abbreviated version using caulk if they're present on your backsplash. Use a putty knife to force a small amount of acrylic or latex caulk into any tile cracks or chips. Wipe away the excess with a rag and allow it to cure for an hour or so. Check the crack to see if you can feel it with your finger. If so, apply more caulk in the same manner to fill the gap completely. 

Repair any grout inconsistencies using a damp finger and acrylic or latex caulk to mimic the existing grout lines. Run a bead of caulk over the missing grout area, slide your finger over the area, pressing the compound into the space. Wipe off the excess with a rag. 

Finally, run a bead of the caulk where it needs repair between the backsplash and the countertop.

Just as if you were prepping any other kitchen walls for paint, the preparation is key for success. As such, scuffing shiny surfaces with sandpaper is crucial to help the primer coat stick. Put on your sanding mask and eye protection. Then, use an orbital sander with sandpaper or a sanding block to achieve this. Any grit between 150 and 220 will work. The goal is to simply scuff the surface rather than make it smooth. Wipe off any sanding dust with a damp sponge before moving forward. Also, double-check your tile repair work and touch it up if necessary.

Applying paint primer is crucial to making your backsplash painting job a masterpiece. Working in small sections, use a smaller paintbrush to apply the primer to the grout lines and cut in the edges. Immediately follow up by using a roller to apply primer to the tile surfaces in the same small area. Repeat until the entire backsplash is complete. If your backsplash and paint color differ drastically, consider adding a second primer coat.

Using the same technique of painting the grout lines and cutting in the edges with a brush, and then the tile surfaces with a roller, apply your epoxy paint or enamel paint. Allow the first coat to dry completely before applying a second coat. After applying the second coat, you can add designs or stencil work if desired.
