Why You Need a Good Waterproof Paint For Showers
Since bathrooms are damp, moisture should be your primary concern when applying a new paint job to your walls. Moisture has two effects on your bathroom walls. Damp air gathers on the walls from steamy baths and showers. And there’s water splashed onto the walls straight from the tub or sink. When moisture penetrates the paint layer and comes into contact with the drywall or plaster underneath, it can damage the paint.
This can cause paint peeling and mold formation. The less permeable the paint layer is, the less moisture can penetrate. Using high-gloss paints was the most common way of coping with bathroom moisture, even before mildew-resistant properties were introduced to the paint. The better the paint finish performs in toilets, the higher the gloss. High-gloss finishes on all surfaces are popular in older bathrooms. While high-gloss paints do not prevent mildew, wiping down those drippy, brown stains common in bathrooms is a breeze. (Read Enamel vs Acrylic Paint)
In favor of Bath Paint, several interior house products are moving away from the bathroom paint name and creating paints to combat moisture. Interior Acrylic Latex Paint, like Bath Paint, has antimicrobial properties and is suitable for trim, walls, and ceilings. A flat finish is porous in a wet setting and absorbs moisture, while a glossy finish causes water to bead and runoff.
Waterproof paints for bathrooms are more expensive than other interior paints, but you can get high-quality paint that will last in the bathroom. Since bathrooms are small, the amount of thick sealed paint you’ll need is usually less than in a standard room. If you don’t need a low-sheen finish in your bathroom, a good-quality satin, semi-gloss, or high-gloss regular paint with antimicrobial additives is washable. It has steam and a moisture-resistant finish, which should suffice.
