3 Expert Tips for Successfully Applying Gloss Paint Over Gloss

1. Condition of the Surface and Quality of the Paint

The most important factor to consider when painting over gloss is the condition of the surface. If it’s in poor condition, it may not adhere to a new layer of paint as well as expected.

It’s also essential to consider the paint’s quality and durability. High-quality paint is more likely to last longer and provide better coverage.

2. Type of Gloss Paint

Another factor to consider when painting gloss over gloss is the paint used. Different types of paint can have different levels of adherence and durability, so choosing a paint that will work best for your project is important.

For instance, painting over oil-based gloss requires a different approach than painting over water-based gloss.

3. Preparation of the Surface

No matter what type of paint you’re using, it’s important to properly prepare the surface before painting. This includes cleaning, sanding, and priming the existing glossy layer.

Additionally, make sure to use a good-quality brush or roller when applying the new layer of gloss paint.

How to Paint Over Gloss With Gloss Paint

Tools and Materials

  • Zinsser’s B-I-N Primer Sealer 
  • Gloss paint
  • Sandpaper (120-grit, 220-grit)
  • Sanding block
  • Tack cloth
  • Paintbrush
  • Paint roller

Step-by-Step Guide

Step 1: Clean the Surface

The first step in painting gloss over gloss is preparing the surface. Remove any decorations, nails, or other objects from the wall. Then, the surface you plan to paint should be clean and dry.

Use a mild detergent and warm water to remove any dirt or grime. Rinse the surface thoroughly and allow it to dry completely. 

It’s important to cover and protect any surfaces you don’t want to be painted. Use a dust sheet or tack cloth, masking tape, and plastic sheets to cover furniture, door frames, windowsills, and other areas near the surface being painted. 

Can I clean my walls using TSP?

It is important to note that while trisodium phosphate (TSP) can effectively clean and degloss surfaces, it may not always be the best option. TSP can strip away too much of the existing paint, leaving the surface vulnerable to damage.

Moreover, TSP can produce hazardous fumes that can be harmful if inhaled. Therefore, it is crucial to take adequate safety measures, such as wearing gloves and a respirator when working with TSP.

Step 2: Remove the Gloss Layer

When repainting an existing painted surface, one of the most important steps is removing the gloss layer of the original paint.

The new paint won’t adhere properly without proper preparation and could end up peeling or chipping off. Here are a few different methods for removing the gloss layer, each with its benefits and drawbacks.

Option 1: Sandpaper

Sanding is a classic method for smoothing surfaces, and it can effectively remove the gloss layer from paint. However, it can be time-consuming and messy, and if you’re not careful, you could remove too much of the original paint or create an uneven surface. It’s important to wear a mask and eye protection when sanding, as the dust can harm your health.

Option 2: Liquid Deglosser

Liquid deglosser is a chemical product that dissolves the gloss layer of paint, making it easier to paint over. It’s generally easier and faster than sanding and less likely to damage the original paint.

However, it can still be messy and potentially hazardous if used incorrectly. It’s important to follow the manufacturer’s instructions carefully, including wearing gloves and working in a well-ventilated area.

Option 3: Paint Stripper

A paint stripper is a strong chemical that dissolves multiple layers of paint, including the gloss layer. It’s fast and effective but can also be quite harsh and potentially damaging to the underlying surface.

It’s important to choose a paint stripper compatible with the surface you’re working on and use it carefully and according to the manufacturer’s instructions. It’s also recommended to wear protective gear such as gloves, eye protection, and a mask.

The best method for removing the gloss layer will depend on the specific situation and personal preference.

Sanding is a traditional approach that can achieve good results if done properly, while liquid deglosser and paint strippers offer faster and more convenient options that require careful use.

No matter which method you choose, always follow safety precautions and use the appropriate equipment to protect yourself and your surroundings.

Step 3: Repair Any Imperfections

Once the gloss layer is removed, inspect the surface for imperfections, such as cracks, holes, or flaking paint. If there are any visible issues, they should be addressed before painting.

Small dents and scratches can often be filled with spackle, while larger cracks may require additional repairs to ensure a smooth finish when painted over.

Step 4: Prime the Wall

Primer provides a protective seal between the existing surface and the new paint, helping to ensure that the new paint adheres properly.

It also helps to hide any imperfections or discoloration on the underlying surface, creating a more even result overall. Before painting over an existing painted surface, applying at least one coat of primer is recommended.

Step 5: Paint

Start by applying an even coat of paint and let it dry completely before adding additional coats. For maximum protection, applying two or three coats of paint is best, allowing each coat to dry completely before applying the next.

Once all the coats are applied and dried, your newly painted surface is ready for use. Remember that you should wait at least 24 hours before cleaning or touching the surface to give it time to dry and cure properly.

5 Tips for Achieving a Smooth and Even Finish

1. Choose the Right Tools

When painting over existing paint, using the right tools is important. Make sure you select the best quality brushes, rollers, and paint sprayers. These tools will help ensure you achieve even coverage and a smooth finish.

2. Clean the Surface

Before painting, it’s essential to clean the surface of the existing paint. Remove any loose or peeling paint with a scraper and sandpaper. You can use sugar soap to clean and rinse the surface with water before painting.

3. Use a High-Quality Primer

Applying a high-quality primer before painting is crucial. The primer will help the paint adhere to the surface and create a uniform finish. Invest in a primer that matches your paint type, whether oil- or latex-based.

4. Apply Paint in Thin, Even Layers

When painting over existing paint, it’s best to apply thin, even layers. Thick layers can cause the paint to crack or peel. Apply a small amount of paint evenly over the surface with a roller or brush. After it dries, apply another thin layer to get the desired color and texture.

5. Allow Each Coat to Dry Completely

It’s essential to allow each coat of paint to dry completely before applying the next layer. Rushing the process can cause the paint to become tacky and smudged, ruining the finish. Follow the manufacturer’s guidelines for drying time for best results.
