Protecting Your Painted Clay Pots: Best Spray Finishes

what protective finish to sray on painted clay pots

Painting clay pots is a fun and easy DIY project that can be done in an afternoon. Clay pots are often painted to add a personal touch, vary the look of the pot, or as a thoughtful gift. To ensure that your painted design lasts longer and doesn't easily chip or scratch, it is important to apply a protective finish. There are several options for protective finishes, including sealants, shellac, and spray acrylics. Sealants can be applied before or after painting and help protect the paint from water and soil staining. Shellac and spray acrylics are applied after the paint has dried and create a smooth finish that seals the paint and protects it from scratches.

Using acrylic paint as a base layer

Painting clay pots is a great way to add a personal touch to your garden or indoor space. If you're using acrylic paint as your base layer, there are a few things to keep in mind to ensure a successful and long-lasting finish.

First, it's important to prepare your workspace and clay pot. Lay down a drop cloth or spread out some newspaper to protect your work surface from paint drips. Then, clean your clay pot to remove any sticky, oily, or powdery residue that may prevent the paint from adhering properly.

When using acrylic paint as your base layer, consider thinning the paint with a small amount of water, especially if your clay pot is unsealed. Terra cotta is very porous and tends to absorb paint quickly. Thinning the paint will make it easier to apply the base layer evenly and quickly using a foam sponge brush. You don't need to paint the very bottom of the pot or the entire inside, as these areas will not be visible once you add your plant.

Allow your base layer to dry completely before moving on to the next step. This may take longer than you think, as acrylic paint can take up to 24 hours or even several days to dry, depending on the thickness of the paint layer. It's important to be patient at this stage, as the pot should not feel sticky or tacky before proceeding.

Once your base layer is completely dry, you may want to consider sealing it with a clear water-based spray acrylic or an acrylic spray sealant. This step is optional but will help protect your paint from scratches and water damage, ensuring your design lasts longer. If you choose not to seal your acrylic base layer, be aware that the paint may blister or peel over time.

Finally, you can add your chosen design on top of your dried and sealed base layer. Get creative and let your inspiration flow! Once you're done, you may want to apply another coat of sealant to protect your design and ensure its longevity.

Applying a sealant before painting

To apply a sealant before painting, start by cleaning your clay pot to remove any sticky, oily, or powdery residue that may cause the paint to look lumpy or fail to stick properly. Once your pot is clean and dry, you can apply a water sealant or a clear sealer to the inside of the pot. This step is optional, but it can help extend the life of your plants by retaining moisture in the soil. Tape off the top edge of the pot before applying the sealant, and follow the directions on the product for proper application. Allow the sealant to dry completely before moving on to the next step.

If you plan to use acrylic paint, thinning the base layer of paint is recommended. Mix a small amount of water with your acrylic paint to thin it out, making it easier to apply quickly and evenly using a foam sponge brush. You can then apply a coat of sealant before painting your design. If you are using spray paint, you may want to apply a base layer of white primer in light, even coats to prevent the paint from running or pooling. Allow each layer to dry completely before applying the next.

It is important to note that not all sealants are suitable for use with acrylic paint. While you can use oil-based paint on top of acrylic paint, doing the reverse may cause issues. Additionally, while Mod Podge can be used as a sealer for acrylic paint, it may not be the best option for terracotta pots as it is water-based and may dissolve due to the clay's properties. Instead, consider using a marine varnish or a sealant specifically designed for outdoor applications.

Sealing with spray shellac

Sealing clay pots is an important step to ensure that your design lasts longer and does not chip or scratch. Shellac is a natural wax that comes from beetle secretions mixed with alcohol. It is a popular choice for sealing painted clay pots and can be purchased pre-mixed or as flakes to be mixed with high-percentage ethanol alcohol.

If you are using Zinsser Shellac Spray, it is recommended to seal the inside of the clay pot twice, waiting 2-3 hours between coats. After the second coat, wait another day or two for the shellac to dry completely. Then, you can paint your clay pot. Once the paint is completely dry, put two coats of shellac over the paint, waiting 2-3 hours between coats. It is important to follow the directions on the can and ensure you cover your entire design.

Shellac is best suited for indoor pots as it cannot hold up to water immersion or being under the soil. If you are looking for a sealant for outdoor pots, you may want to consider a natural oil-based sealant, a non-toxic penetrating sealer, or an acrylic sealant.

Additionally, if you are using acrylic paint on your clay pots, it is recommended to seal the inside of the pot before painting the outside to prevent water from migrating through and damaging the paint over time.

Using oil-based paint on top of acrylic paint

Painting clay pots is an easy and inexpensive way to dress up your garden or personalise a plant gift. Clay pots are usually painted with acrylic paint or spray paint.

If you're using oil-based paint on top of acrylic paint, it's important to note that the pot must be completely dry before applying the oil-based paint. Acrylic paint should be waterproof once it's dry, but applying an additional sealant can provide extra protection. Allow the acrylic paint to dry for at least 24 hours, or until it no longer feels sticky or tacky.

Before applying oil-based paint, consider sealing the acrylic paint with a clear water-based spray acrylic or a clay pot sealer. This will help protect your design and prevent chipping or scratching. You can then apply the oil-based paint on top, following the directions on the paint container.

It's worth noting that some sources suggest avoiding painting the inside of the pot, as it may interfere with drainage. Additionally, if you plan to use vinyl lettering or decorations, sealing both before and after applying the vinyl is recommended to prevent it from coming off.

Adding vinyl to clay pots

When it comes to decorating clay pots, there are various methods to consider, from painting to adding vinyl. Here are some detailed instructions specifically for adding vinyl to clay pots:

Preparing the Clay Pot

Before adding vinyl to a clay pot, it is essential to prepare the surface. Start by cleaning the pot, ensuring there is no sticky, oily, or powdery residue on the clay as this can cause the paint or vinyl to look lumpy and may affect its adhesion. Once the pot is clean, you can apply a water sealant to the inside, which can help extend the life of the plant by retaining moisture in the soil. Tape off the top edge of the inside of the pot before applying the sealant, and follow the directions on the product for the best results.

Designing and Cutting the Vinyl

When working with vinyl, it is crucial to measure the surface area of the pot accurately and create your design accordingly. If you plan to add text, consider the font size and style to ensure it fits well on the curved surface of the pot. Use a cutting machine to cut through the vinyl, being careful not to cut the backing sheet. If you are working with multiple colours of vinyl, you can create registration marks to ensure the layers align perfectly.

Applying the Vinyl

Applying vinyl to a curved surface can be challenging and may require some practice. One suggested method is to use transfer paper to apply the vinyl to the pot, lining up the design with the top of the pot and smoothing it down gradually. Another technique is to use the "taco" bend method, where you hold each side of the transfer sheet and bend them upwards, starting with the centre and then continuing with the sides from the middle to the edge.

Sealing the Vinyl

To protect your vinyl design and ensure its longevity, sealing is essential. You can use a clear water-based spray acrylic or a spray sealant to create a protective barrier over your design. Allow the sealant to dry completely before handling the pot to avoid any smudging or unwanted stickiness.

Additional Tips

When working with vinyl, especially on curved surfaces, it's normal to encounter some challenges. One trick to removing small pieces of vinyl from the backing sheet is to use a sharp tool to jab through the vinyl and the backing sheet, carefully pulling out the pieces. Additionally, when working with multiple colours, you can conserve vinyl by strategically positioning your design within the cutting window.
