Yes, after applying two coats of Kilz as your primer, you can proceed to paint the wood toy box using acrylic craft paints. Acrylic paints are a great choice for this project as they provide vibrant colors, good coverage, and adhere well to a variety of surfaces, including primed wood. Once you have finished painting with the acrylic craft paints and allowed them to dry completely, you can seal the toy box with a clear coat to protect the painted surface and give it a glossy finish. When choosing a clear coat, opt for one specifically designed for acrylic paints to ensure compatibility and durability. Additionally, make sure to follow the manufacturer’s instructions on application and drying times for both the acrylic paints and clear coat to achieve the best results. Overall, by following these steps, you can create a beautifully painted and protected wood toy box that will stand the test of time while showcasing your creative skills.
