When it comes to preparing previously painted cabinets for a new coat of high gloss paint, sanding is generally the recommended method rather than using acetone as a liquid de-glosser. Acetone is primarily used as a solvent for removing paint or cleaning surfaces, but it may not be as effective in de-glossing high gloss paint finishes. Sanding is a more reliable way to create a suitable surface for paint adhesion.
Here's a suggested process for preparing your cabinets:
Remove Cabinet Hardware: Take off all the cabinet hardware, such as handles and knobs.
Clean the Surfaces: Use a mild detergent and warm water to clean the cabinet surfaces, removing any dirt, grease, or grime. Rinse thoroughly and allow the cabinets to dry completely.
Sand the Cabinets: Lightly sand the entire cabinet surfaces using fine-grit sandpaper (e.g., 220-grit). Sanding will help to roughen the surface and remove the glossiness, allowing the new paint to adhere properly. Make sure to sand evenly and remove any loose or flaking paint.
Remove Dust: After sanding, wipe down the cabinets with a tack cloth or a damp cloth to remove any sanding dust. It's essential to have a clean and dust-free surface before applying the new paint.
Prime (if necessary): Depending on the condition of the cabinets and the type of new paint you're using, you may need to apply a primer before painting. Some high gloss paints may require a primer for better adhesion and to prevent any bleed-through from the previous paint. Consult the paint manufacturer's instructions to determine if primer is recommended.
Apply High Gloss Paint: Once the cabinets are properly sanded and cleaned, you can apply the new high gloss paint using a brush, roller, or sprayer, depending on your preference and the desired finish. Follow the paint manufacturer's instructions regarding application techniques, drying times, and the number of coats required.
By sanding the cabinets, you create a surface that promotes better paint adhesion and ensures a smoother and more durable finish.
