What You’ll Need

Before you get started with prepping and painting, you’ll need to gather the proper materials and tools:

Painting Supplies

High adhesion primer
100% acrylic latex paint in your chosen color
Angled trim paint brush
Paint roller and tray set
Painters tape
Paint stirring sticks
Paint tray liners
Rags and paper towels

Prepping Supplies

TSP substitute or mild cleaner
Scrub brush or pad
Sandpaper in various grits
Shop vacuum
Mineral spirits
Clean rags

Safety Gear

Rubber gloves
Safety goggles
Dust mask
Drop cloths

Be sure to use high-quality primer and 100% acrylic latex paint formulated especially for tile. The paint should also have built-in mold and mildew resistance. Gather all your prepping supplies, tools, and safety gear before you begin.

Preparing the Tile Surface

Proper prep is crucial for getting paint to adhere correctly to the tile and grout. Follow these steps to prepare your mosaic backsplash surface:

1. Clean the Tiles Thoroughly

The tiles need to be completely free of grease, soap scum, and grime. This allows the paint to bond properly. Mix up a tile cleaning solution using TSP substitute or a comparable degreasing cleaner. Using a scrub brush or pad, scrub every inch of the tile and grout to remove built-up residue and sediments. Rinse thoroughly with clean water and let dry fully.

2. Sand the Tiles

Lightly sanding the tiles gives the paint something to grip onto. Use fine 120-150 grit sandpaper and gently sand in a circular motion. Make sure to hit the edges and grout lines in addition to the tile surface. Sand just enough to scuff up the glaze coating, but not enough to etch or damage the tile. Wipe away all dust with a damp rag.

3. Clean Out Grout Lines

Use a sharp utility knife or grout saw to scrape out the existing grout about 1/8 inch deep. This removes loose or cracked grout so you can apply fresh grout after painting. Thoroughly vacuum out all grout debris.

4. Wash With Mineral Spirits

Wipe down the entire surface with mineral spirits using a clean lint-free rag. This removes any remaining greasy residue and fully preps the tile for priming and painting. Let the mineral spirits dry completely before moving onto priming.

Thorough cleaning, light sanding, and washing with mineral spirits are the essential prep steps for getting your mosaic tile backsplash ready for a painted makeover.

Priming the Tiles

After thorough prep, it’s time to apply primer. Using the right primer is key for maximum paint adhesion. Look for these features when selecting a primer:

Formulated specifically for tile
Bonds to smooth or glossy surfaces
Penetrates porous grout
Mold and mildew resistant

Stir the primer thoroughly before pouring some into a paint tray. Use an angled trim brush to carefully apply primer over the entire surface of the tile and grout lines. Get into corners and crevices for complete coverage. Apply a second coat of primer if needed for a perfectly prepped surface.

Allow the primer to dry fully per the manufacturer instructions before moving onto painting. Properly primed tile allows the paint to adhere tightly for a long-lasting finish.

Painting Techniques and Application

Once your mosaic backsplash tile is fully prepped and primed, you’re ready to start painting. Follow these application tips and techniques for flawless results:

1. Use Painter’s Tape for Clean Lines

Carefully apply painter’s tape around the outer edges of the backsplash area. Also tape off any adjacent surfaces you don’t want to get paint on. This helps create super straight edges and crisp paint lines.

2. Apply With Trim Brush and Mini Roller

Use a high-quality angled trim brush to cut-in around the edges and get into grout lines. Then use a 4-inch mini foam roller and tray to apply the paint over the body of the tiles. This ensures complete, even coverage.

3. Work Top to Bottom

Paint a section at a time starting at the top and working your way down methodically. This prevents drips from messing up freshly painted sections.

4. Apply Thin Coats

Apply the paint in thin, even coats rather than globbing it on thickly. Thin coats allow the paint to fully adhere and dry properly.

5. Let Dry Between Coats

Allow each coat to dry fully according to the manufacturer directions before adding another coat. Typically 2-3 thin coats provides ideal coverage.

Take your time with the painting process for best results. Tackle small sections, use light coats, and let the paint dry thoroughly between applications.

Painting Grout Lines

For a seamless finished look, the grout lines will also need painted. There are a couple options for painting grout:

1. Match the grout color to the tile paint color – This gives a minimal, monochromatic look. Use a small trim brush to carefully paint down into the cleaned out grout lines.

2. Use contrasting grout color – For more definition, choose a darker grout color that contrasts with the tile color. After the main tile painting is complete, use a small flexible brush to paint the contrasting color down into the grout lines.

No matter which grout painting technique you choose, be sure to protect the freshly painted tiles around the grout line. Remove all excess grout paint right away with a damp rag before it can dry.

Finishing and Sealing the Painted Tiles

Once your tile painting is complete, there are just a few more finishing steps:

Let the paint cure fully for at least 24-48 hours. Avoid washing or getting the surface wet during this period.
Carefully remove all painter’s tape. Pull slowly parallel to the surface to avoid peeling up paint.
Apply a grout sealer to protect the fresh painted grout lines.
Finish up by applying a tile and grout sealer over the entire surface. This adds an extra layer of protection.

After proper curing time, cleaning, and sealing, your newly painted backsplash is ready to enjoy! Proper maintenance will keep the finish looking fresh for years to come.

How to Choose Paint Color for Mosaic Tile Backsplash

The great thing about painting a backsplash is that you can customize it to any color palette you desire. Here are some tips for selecting the perfect paint color:

** coordinate with counter and cabinet colors:** Choose a color that ties in with your existing kitchen or bathroom color scheme and materials. A shade that complements the counters and cabinets will give a cohesive look.
Consider undertones: Mosaic tiles lend warmth with their texture. Pair with cool paint tones like blues or greens to balance the warmth. Avoid going too dark or the texture may get lost.
Look at color trends: Modern backsplash paint colors include lighter shades of blue, green, gray, and taupe. These lend an airy, updated look.
Use your tiles as inspiration: Pull a unique accent color from the tiles themselves to paint the body of the backsplash. This creates a custom complementary palette.
Envision the finished space: Picture the paint color in the context of the whole room before committing. Paint large sample swatches to get an accurate impression.

Take your time deciding on a mosaic tile paint color. Grab paint swatch samples and live with the colors before making a final selection. This ensures you choose the perfect shade for your kitchen or bath.
