Introduction

Have you ever wondered whether you can put latex stain over oil stain?

As a qualified painter and decorator, I've come across this question countless times.

In this article, I will provide you with detailed information on this topic to help you make an informed decision for your next painting project.

Quick Summary

In short, applying latex stain over oil stain can be done, but proper preparation is crucial.  You'll need to clean, degloss, and prime the surface before applying the latex stain to ensure a long-lasting and durable finish.

Understanding Latex and Oil Stains

Before diving into the specifics, it's essential to understand the key differences between latex and oil stains:

  • Latex Stains: Water-based, easy to clean, quick-drying, and more eco-friendly
  • Oil Stains: Oil-based, more durable, longer drying time, and better penetration into wood

Steps to Apply Latex Stain Over Oil Stain

  1. Clean the Surface: Remove dirt, grease, and any loose or peeling paint from the surface. You can use a mild detergent and a stiff brush to scrub the area. Rinse thoroughly and allow it to dry completely.
  2. Degloss the Surface: Sand the surface lightly with fine-grit sandpaper (150-220 grit) to remove the glossy sheen from the oil stain. This step is crucial for better adhesion of the primer and the new latex stain.
  3. Apply a Bonding Primer: Choose a high-quality bonding primer that is specifically designed for adhering to oil-based surfaces. Apply the primer according to the manufacturer's instructions and allow it to dry fully.
  4. Apply the Latex Stain: Once the primer is dry, you can apply the latex stain using a brush, roller, or sprayer. Follow the manufacturer's recommendations for the number of coats and drying time between coats.
  5. Seal the Surface (Optional): Depending on the location and usage of the stained surface, you might want to apply a clear sealer for added protection.
