Painting Drywall Behind Cabinets: Worth The Effort?

Painting drywall behind kitchen cabinets is a topic that has sparked debate among professionals. Some argue that it is unnecessary as the walls will be hidden by the cabinets, while others believe it is crucial to prevent moisture and vapour penetration, which can cause odour and mould issues. While some contractors suggest painting before cabinet installation for ease of access, others recommend painting after to avoid touch-ups. Ultimately, the decision may depend on personal preference, future plans for the space, and the level of finish desired.

Priming and painting drywall before cabinet installation

Painting drywall is a relatively easy process, but it requires some preparation. It is recommended to prime and paint drywall before installing cabinets. Here are the steps for priming and painting drywall before cabinet installation:

Inspect and Prepare the Drywall

Before priming and painting, it is important to inspect the drywall for any gouges or dings. If there are any imperfections, fill them in using drywall mud or a similar paste solution. Next, use a pole sander to smoothen the surface of the drywall. Ensure that you properly clean the drywall by vacuuming and wiping it down with a damp cloth to remove any dust.

Prime the Drywall

Priming is a crucial step before painting drywall. It helps to ensure that the paint adheres well and is not affected by temperature changes or moisture. Choose a suitable primer for your drywall, such as a latex-based primer or a PVA primer. Apply the primer evenly to the drywall using a roller or a spray. Allow the primer to dry completely before proceeding to the next step.

Paint the Drywall

Once the primer is dry, you can start painting the drywall. Select a high-quality paint that is suitable for drywall, such as a premium acrylic latex primer or paint. Apply the paint in small strokes, ensuring that you cover the entire surface of the drywall. Allow the paint to dry completely. You may need to apply a second coat of paint for a more consistent and durable finish.

Protect the Surrounding Area

When painting drywall, especially in a kitchen or bathroom, it is important to protect the surrounding area. Use painter's tape to cover any cabinets, countertops, or other surfaces that you do not want to get paint on. This will help create a neat and professional finish.

Benefits of Priming and Painting Before Cabinet Installation

Priming and painting drywall before installing cabinets offer several advantages. Firstly, it provides added protection to the drywall, helping to prevent moisture absorption, odour, and the growth of mould or mildew. Secondly, it saves time and effort, as it is easier to paint a wall without cabinets in the way. Finally, it ensures a more uniform and aesthetically pleasing result, as you can paint the entire wall without having to worry about cutting in or masking around the cabinets.

Sealing drywall to prevent moisture and vapour penetration

Sealing drywall is essential to prevent moisture and vapour penetration, which can lead to mould and mildew growth. While drywall is a fantastic material for creating interior walls due to its lightweight and easy installation, it is susceptible to moisture damage. Therefore, it is crucial to take preventive measures, especially in areas like bathrooms and basements, or wherever there are water pipes, drains, or sump holes nearby.

Preparation and Materials:

Ensure your work area is clear of any furniture, carpets, or other obstacles. Gather the necessary materials, including a primer designed for high-humidity areas, a paintbrush or roller, a wall putty knife, sandpaper, and joint compound. It is also recommended to have towels and rags on hand for cleanup.

Select the Right Primer:

Choose a primer specifically formulated for walls in high-humidity areas. Read the directions thoroughly to ensure it is suitable for sealing drywall from moisture damage.

Fill Joints and Holes:

Apply joint compound to any gaps or joints between drywall boards. This step helps keep moisture out and prevents warping due to increased moisture content. Smooth the compound with a trowel or putty knife and let it dry completely before sanding down any excess with fine-grit sandpaper.

Apply Primer:

Use a paintbrush or roller to apply an even coat of primer to the entire drywall surface. Start in one corner and work your way across, ensuring each section is completely covered. Allow ample time for drying, typically around 24 hours.

Painting:

Once the primer is dry, it's time to paint. Urethane paint is recommended as it provides an extra layer of protection against moisture and an attractive finish. Use a high-quality brush or roller for even coverage, and apply at least two coats, allowing each layer to dry fully before the next.

By following these steps, you can effectively seal your drywall, preventing moisture and vapour penetration, and ensuring the longevity of your walls and cabinets.

Painting drywall to prevent mould and mildew

Painting drywall is an effective way to prevent mould and mildew, which can cause serious health issues and structural damage if left untreated. Here are some instructive tips to prevent mould and mildew when painting drywall:

Prime and Paint the Drywall:

Priming and painting drywall is essential to prevent the penetration of vapours and moisture. Even if the drywall is behind cabinets, it can still be susceptible to moisture and vapour penetration, which can lead to mould and mildew growth. Priming creates a seal that protects the surface and inhibits the growth of mould and mildew.

Choose the Right Paint:

When painting drywall to prevent mould and mildew, select high-quality, mould-resistant, or anti-mould paints. These paints contain fungicidal or antimicrobial chemicals that repel mould and create an environment where it cannot grow. Mould-resistant paints are especially useful in high-moisture areas like kitchens and bathrooms.

Prepare the Surface:

Before painting, ensure the drywall surface is clean and dry. Remove any organic matter, peeling paint, or discolouration. Treat the surface with a fungicidal wash to kill any existing mould spores. You can also use a mould remover treatment as an additional preventative step to stop mould or damp from returning.

Fill and Sand:

If the mould has caused any damage to the drywall, such as cracks or holes, fill them before painting. Once the filler has dried, use fine abrasive paper to smooth the surface, creating a uniform base for the primer and paint to adhere to.

Proper Ventilation and Moisture Control:

Maintain proper ventilation and control humidity levels to prevent mould and mildew growth. Use exhaust fans, dehumidifiers, and air filtration systems to reduce moisture and improve air circulation. Address any sources of excess moisture, such as leaks or poor insulation, to create an unfavourable environment for mould and mildew growth.

By following these steps, you can effectively prevent mould and mildew when painting drywall. Remember to always wear the appropriate personal protective equipment (PPE) when working with mould or paint.

Finishing drywall to the same level as the rest of the wall

Finishing drywall to a standard that matches the rest of the wall is a crucial step in ensuring a consistent and appealing final product. Here are some detailed instructions and considerations to help you achieve this:

Drywall Finishing Levels:

The drywall finishing standards, ranging from Level 0 to Level 5, provide a framework for achieving the desired finish. Level 0 indicates that no finishing work has been done beyond installing the drywall boards. Level 1 involves taping the seams, while Level 2 includes a thin coat of joint compound over the tape and filling screw holes. Level 3 involves an additional coat of compound, and Level 4, the classic drywall finish, involves another coat and sanding for a painted or wallpapered surface. Level 5, the highest level, includes a skim coat for a mirror-smooth surface, ideal for high-gloss paint or intense lighting.

Priming and Painting:

Before painting drywall, it is essential to prime it with the appropriate primer sealer. New drywall is porous, and without priming, paint may absorb unevenly. A high-quality latex primer sealer is recommended to ensure a uniform finish. After priming, use a roller or sprayer to apply two coats of high-build primer, followed by two coats of your chosen paint colour.

Sanding and Cleaning:

Before priming and painting, it is advisable to give the new drywall a light sanding to smooth the surface. Use a shop vac to remove drywall dust, paying attention to higher areas. Follow up with a damp cloth to wipe down walls and corners, ensuring the removal of all dust. Be cautious not to use too much water, as it can damage the drywall.

Lighting and Temperature:

Ensure proper lighting and an interior temperature above 60°F before starting work. Adequate lighting helps identify defects, and temperature control prevents movement in the walls and seams, reducing the likelihood of new defects.

Repair Work:

Try to make any necessary drywall repairs before painting. Repairs made after painting can create an uneven surface and an irregular finish. If repairs are needed after the prime coat, remember to seal the repaired areas again before the intermediate coat.

By following these steps and considerations, you can achieve a drywall finish that seamlessly matches the rest of the wall, creating a cohesive and aesthetically pleasing space.

Using painter's tape to protect cabinets and countertops

Painting is an important step in maintaining the durability of your kitchen. It helps to prevent the buildup of grease and vapour, which can lead to odours and mould growth. To achieve a clean and polished look, it is essential to use painter's tape to protect your cabinets and countertops during the painting process.

Painter's tape is specifically designed to prevent paint from seeping onto surfaces like countertops and cabinets. It is typically blue, can be torn easily with your fingers, and has the right amount of stickiness to adhere to various surfaces without leaving a sticky residue. When using painter's tape, it is important to use long pieces of tape whenever possible and to ensure that the tape is firmly adhered to the surface.

• Clean the surfaces of your cabinets and countertops to remove any dust or grease. A clean surface will ensure better adhesion of the tape.
• Start by lining up the top edge of the tape with the edge of the cabinet or countertop. Hold the roll directly next to the surface as you apply the tape.
• After tearing the tape just past the bottom edge, use a putty knife to create a slight crease. This will help you achieve a clean, straight edge.
• You can use the putty knife to tuck the tape underneath any wood framing or edges. This ensures that the tape is securely in place.
• For curved surfaces or intricate shapes, it is best to use shorter pieces of tape. Work carefully around the curves to ensure full coverage.
• When taping off countertops, use long pieces of tape whenever possible. This will create a straight line and protect the countertop from paint drips.
• For corners or irregular shapes, overlap pieces of tape to create a seamless barrier. This ensures that no paint seeps through.
• Press down along the tape's edge with your fingernail or a plastic card to ensure a secure hold.
• Before applying paint, test the adhesion of the tape by applying a small test strip and removing it after a few minutes. If it peels off cleanly without lifting the paint, you're ready to start painting.
• Always remove the tape before the paint is completely dry to avoid peeling or lifting the paint. The ideal time to remove the tape is when the paint is still slightly tacky.
• When removing the tape, peel it away from the surface at an angle. This will help prevent the tape from pulling up any paint from the edges.
• If you are concerned about the paint peeling, use a sharp knife to carefully cut along the edge of the tape, breaking the seal between the paint and the tape.

By following these steps and tips, you can effectively use painter's tape to protect your cabinets and countertops during your kitchen painting project. Remember to choose the right type of tape for your specific surface and always test its adhesion before starting your project.
