Steps to Paint Over High Gloss Surfaces

1. Clean the Surface

Use TSP or a degreaser to clean the high gloss surface thoroughly. This step ensures that there is no dirt, grease, or oils which can affect the adhesion of the primer and paint.

2. Sand the Surface

Lightly sand the high gloss finish with 220-grit sandpaper. This step is crucial to help the primer and paint adhere better. You don’t need to remove all of the gloss; just creating a rough surface.

3. Remove Dust

Wipe down the sanded area with a clean damp cloth to remove dust and debris. Allow it to dry completely before proceeding.

4. Apply Primer

Use a high-quality primer suitable for glossy surfaces. Apply a thin, even coat and allow it to dry according to the manufacturer's instructions. If the primer feels rough after drying, you can lightly sand it again with fine sandpaper (320-grit) to create a smooth surface.

5. Paint

Once the primer is dry, apply your chosen paint in thin, even coats. Depending on the color and type of paint, you might need two or more coats. Allow each coat to dry completely before applying the next.

6. Finish

After the final coat of paint has dried, inspect the surface. If needed, you can lightly sand and apply a final coat for an even smoother finish.

Create a Safe Work Space

Before starting, it’s essential to create a safe and organized work space:

Remove Furniture and Decor

Take out chairs and furniture, remove any paintings or wall art. Keep your workspace clear to avoid obstacles.

Protect Your Floor

Use plastic sheeting or drop cloths to cover the floor. Even if the area isn’t directly beneath your work, paint can drip or splatter. Cover the area well to protect it from damage.

Masking Off Areas

Apply painter’s tape to mask off areas you don’t want to get paint on. This helps protect your floor and any edges or trim.

Wear Safety Gear

Wear rubber gloves and a face mask for safety. Rubble and dust from the gloss paint can irritate your lungs and throat.

De-glossing the Paint

For surfaces that are still glossy, you can de-gloss them with a combination of sanding and cleaning:

Sanding

Sand the paint in circular motions with 180-grit sandpaper. The glossy surface needs to be removed so the new paint can adhere properly.

Cleaning

Combine dish soap, white vinegar, and warm water in a bucket. This solution helps lift dirt, dust, and grime from the surface.

Cleaning the Paint

Dip a clean sponge into the solution and wring it dry. Use the sponge to apply gentle, circular motions to the surface to clean it thoroughly.

Drying the Paint

Use a clean, dry towel to wipe away any moisture. Make sure the paint is completely dry before applying primer and paint.

Applying Your Primer and Paint

With the surface prepared, it’s time to apply primer and paint:

Applying the Primer

Use a paintbrush or roller to apply a bonding primer in broad strokes. Follow the manufacturer’s instructions for drying times and coverage.

Allowing the Primer to Dry

Wait at least 1 hour to allow the primer to dry completely. Use a fan to speed up the drying process if needed.

Applying the Paint

Use broad strokes to apply an even layer of paint. Start at the top of the surface and work your way down for even coverage. Begin with a satin or eggshell finish which are easier to apply.

Allowing the Paint to Dry

Let the paint dry for at least 1 hour. Test for dryness by lightly touching it with your finger. After the first coat, apply a second coat for complete coverage. Allow it to fully dry before inspecting the final finish.
