Best interior painters near Glendora, CA

You don’t necessarily have to remove all the old paint before repainting your deck, but it’s best to remove as much as possible to ensure a smooth and long-lasting finish. Prioritize scraping off loose, peeling, or flaking paint, and sand down rough areas to create a smooth surface for the new paint to bond with.

You can apply stain over peeling stain, but it’s not a good idea. Your old stain will get in the way of your new stain bonding to the wood, so you’re likely going to see the same issue again shortly after application. Your best option is to sand off the old stain and clean the surface thoroughly before applying new stain.

The biggest issue with painting your interior walls with exterior paint isn’t the way the paint looks or performs—it’s the lack of ventilation. The higher quantities of VOCs in exterior paint will have a harder time dispersing in an enclosed space, so do everything you can to direct them out—like turning on a fan and opening your windows and doors. Afterward, you can simply prime and redo your walls with interior paint, and no one will know the difference.

Yes, you can paint over old exterior paint, but success depends on the condition of the existing paint and proper surface preparation. If the previous coating is in good shape (not cracked, peeling, or flaky), you can paint over it with less prep work. However, for the most durable and professional-looking results, follow these key preparation steps:

• Clean the Surface: Thoroughly clean the exterior to remove all dirt, grime, and mildew. A pressure washer can be very effective for this.

• Scrape and Sand: If the old paint is peeling, cracked, or flaky, you must scrape off all loose paint. After scraping, sand the surface to create a smooth, even base for the new paint. Sanding is especially important for wood siding.

• Apply Primer: Using a quality exterior primer is highly recommended. It ensures the new paint adheres properly, improves durability, and provides a uniform finish. If you are painting a lighter color over a dark one, a tinted primer will help cover the old color more effectively.

Some brands offer paint-and-primer-in-one products for convenience. Taking the time to prepare the surface properly will not only increase your home's curb appeal but also help protect your siding and extend its life.
