How To Paint Masonite Bathroom Walls
John Campbell 
Masonite is indeed an engineered wood product that was once commonly utilized in older homes for interior structure and siding. Masonite, commonly known as hardboard, is a tough and strong material that, like most wood products, is susceptible to moisture damage.
To create a long-lasting, professional appearance, bathroom walls built of Masonite should be thoroughly prepared before painting.
1. Use drop towels to cover bathroom fixtures and floors from paint drips.
2. Using 120-grit sandpaper, sand any glossy sections of the Masonite walls until they are dull. To avoid gouging or removing too much material, use a sanding block or palm sander with a light touch.
3. Use a wood water-repellent compound to coat the Masonite walls. Excessive moisture causes mould and mildew on bathroom walls, and Masonite is water-resistant but not waterproof. For drying time, follow the product’s instructions.
4. Apply one coat of high-quality primer to the walls. Before painting, let the primer dry completely.
5. Use a high-quality latex paint to apply two coats. Two thin coats of paint will stick to the wall better than one thick coat. Let the first coat dry thoroughly while going on to the second.
Two light coats of paint produce a superior finish than one hefty application. Whenever the temperature is over 50 ° F and dew is likely to form, paint at least 2 hours ahead of time. If painting large surfaces, rather than using a paint bucket, utilize a 5-gallon container and a metal roller grid. Whenever the sun is beaming straight on the outer walls, avoid painting them.
