Top 7 Varieties of Paint for Bathroom Ceilings and Comparison of the Best

The paint for painting the ceiling in the bathroom should have an environmentally friendly composition, that is, it should not emit toxic substances in conditions of high humidity. This type of paints and varnishes used in damp rooms, after application to the surface, should create a moisture-resistant film. Before painting, the ceiling should be treated with disinfectant primers to prevent the development of mold.

bathroom paint requirements

For painting the ceiling in the bathroom, choose moisture-resistant paints and varnishes (painting materials), which create a strong and durable coating. In a small area, the top is usually painted white. It is important that the paint, after a long period of application, does not turn yellow, crack, swell, crumble.

Characteristics that paint materials must have to paint a bathroom ceiling:

• impermeability;
• vapor permeability;
• strength;
• sustainability;
• color fastness, light fastness;
• excellent adhesion to the base (concrete, wood, plaster, plastic, plasterboard);
• elasticity (resistance to periodic increases in temperature and humidity);
• resistance to wet cleaning;
• environmentally friendly composition.

The paint used for painting the ceiling should be viscous, not flow during painting, set quickly and dry in natural conditions (at room temperature). The paint layer after application and hardening must not emit toxic fumes.

Suitable formulation varieties

To paint the ceiling, you can buy water-based or solvent-based paints and varnishes. Each type of paint has its own advantages and disadvantages.

Acrylic

The most suitable paint materials for the ceiling in the bathroom are acrylic dispersions based on polymers and water. These paints, after application and drying, create a durable film on the surface. Acrylics are usually sold in white and can be tinted in a variety of shades. They are applied to the surface with a foam roller, synthetic brush or spray gun.

Silicone

Water mixable silicone resin paint is perfect for painting ceilings. This type of paint is unique: it penetrates the pores of the surface, protects against water penetration, allows water vapor to pass through, creating a breathable coating. It is applied by brush, roller, spray gun.

Silicate

Water-dilutable paint based on liquid potassium glass. Creates a durable, waterproof coating. Suitable for concrete, plaster surfaces, bricks. Available in white, tinted in any shade. It is applied by brush, roller, paint gun.

PVA-based

PVA (acrylic) based paints are usually used for painting ceilings in dry rooms. Such paint materials can be applied to concrete, plaster, wood, plasterboard, a surface pasted with wallpaper.

Latex

Water-dilutable latex paints are suitable for painting ceilings in wet areas. Paint materials can be applied to concrete, plaster and brick substrates.

water-based

A water-based emulsion creates a durable, moisture-resistant coating on the ceiling. In the composition of these paint materials, in addition to water, there are various resins.May have names: acrylic, latex, silicone, polyvinyl acetate, silicate water-based paint.

E-mail

Unlike water-based and water-dispersed paint materials, enamels contain resins and solvents with a pungent odor, which evaporates after the paint layer dries. These paints and varnishes create a more durable and moisture-resistant coating. Types of enamels for the bathroom ceiling: alkyd, nitrocellulose.

How to paint correctly

Painting the ceiling in a room with high humidity should consist of two main stages: preparation and the painting process itself.

Preparation of tools and materials

Before painting, you need to purchase the following tools and materials:

• paint sprayer (for uniform and even coloring);
• a roller on foam rubber (for water-based paints) or on a fur coat (for solvent-based paints);
• synthetic or natural brushes;
• sponges, rags;
• solvent for removing stains;
• a primer adapted in composition to the surface and to the painting materials;
• putty, spatulas, floats (for leveling the ceiling);
• painting based on the surface of the painted surface.

Before buying paint materials, you need to calculate the paint consumption.To do this, you need to calculate the area to be painted in meters. This value is found by multiplying the width of the ceiling by its length. Usually one liter of paint materials is enough for 5-10 m². meters of area.

How to prepare the surface

Before painting, the ceiling must be carefully prepared: remove the crumbly layer of the old coating, give the surface an even appearance, putty the cracks. The enamel can be applied over an old adherent layer of paint. Water paint materials require a rough coated surface, such compounds will flow from a smooth ceiling.

It is recommended to apply a special antiseptic primer before applying any paint and varnish materials. The ceiling in a damp room should be treated with fungicidal and antibacterial agents. For better adhesion of paint materials, it is advisable to paint the bathroom top with a deep penetration primer.The type of primer must match the type of substrate (for concrete, plaster, wood) and the type of paint.

It is impossible to paint the ceiling treated with an alkyd primer with an acrylic compound, and vice versa.

Paint application

The ceiling is painted with a spray gun or a long-handled roller. Joints and corners are pre-painted with a brush. The paint is applied in uniform, wide strips that overlap by 2 centimeters. You need to paint the ceiling quickly. Painting the top in a bathroom usually takes no more than 30 minutes. The paint is applied to the ceiling in a thin layer. Before painting, the optimum viscosity of the composition is achieved.

In order to paint evenly on the surface, it is recommended to apply 2-3 coats of paint to the bathroom ceiling. It is imperative to respect the intercoat interval for the drying of the paint. After applying the topcoat, it is advisable to visually assess the result. The coat of paint should evenly cover the entire surface of the ceiling.

Final works

At the final stage, it is necessary to remove all paint stains from the walls and floor. Fresh drops of paint can be wiped off with a sponge and plain water. Thinner is needed to remove dried paint. After painting the bathroom ceiling, you should wait at least 24 hours for the paint layer to dry and undergo the polymerization process. It is advisable to use the bathroom for 7 days after the renovation.

Common Mistakes

It is strictly prohibited:

• apply paint to a wet surface (the paint layer may swell);
• paint the collapsing ceiling (the paint will not last long);
• Dilute water-based paint and varnish with solvents (the chemical composition of the mixture will change).

Additional tips and tricks

A few tips to make the process of painting the ceiling easier:

• it is better to prime the surface before applying the first coat of paint;
• after applying the primer, you need to wait at least 24 hours;
• it is desirable to paint the ceiling with a sufficiently viscous solution, too liquid paint will flow;
• a uniform and uniform coating is achieved when using a paint sprayer;
• ceiling paint is applied in thin layers;
• before applying each new coat, wait a few hours for the paint to dry;
• The paint material should dry with the doors open at room temperature.
