Spray sealers are best held at least 8 inches from the rock
Spray sealers are an effective way to seal painted rocks. They are easy to use and provide great coverage. Popular brands of spray sealers include Krylon and Rust-oleum. Spray sealers are also available in different finishes, such as glossy and matte.
When using a spray sealer, it is important to hold the can at least 8 inches away from the rock. Holding the can too close will result in uneven coats of sealer on the rock. It is recommended to start with a light mist coat first and then build up thicker coats. It is crucial to avoid spraying too much sealer, as it can cause dripping or running on the rock's surface.
Before applying the sealer, ensure that the painted rock is completely dry. It is suggested to let the rock dry overnight before sealing. Additionally, choose a calm day with no wind to avoid wasting sealer and to prevent accidental spraying of nearby plants or structures.
To achieve the desired finish, it is advisable to test different sealers on a spare rock. This will help determine the best product and application process for your painted rocks.
Overall, by following these instructions and holding the spray sealer at least 8 inches from the rock, you can effectively seal your painted rocks and ensure their longevity.

Avoid brush-on sealers with Posca pens as they can cause smearing
Sealing painted rocks is a great way to prolong the life of your artwork. There are many different options when it comes to sealing rocks. Sealers come in paint-on, pour-on, or spray-on variants.
Posca pens are perfect for painting on rocks as they allow you to control the application of rich, opaque water-based paint. They dry rapidly, and you may write over them with other Posca products without worrying about smudging, smearing, or bleed-through. However, it is important to note that some brush-on sealers may cause Posca ink to smear.
To avoid smearing when using Posca pens, it is recommended to use a spray sealer to set the ink first. A spray sealer, such as Krylon acrylic sealer, can be held at least 8 inches from the rock to create a light mist coat. This will help to prevent the ink from running or smearing. Once the light coat has dried, you can then apply a heavier coat at an angle to hit the sides of the rock.
If you prefer to use a brush-on sealer, it is crucial to test the product first on a small area or a separate rock. Apply a thin coat of the sealer with a bristle or sponge paintbrush and allow it to dry thoroughly. If the Posca ink does not smear, you can continue with this sealer. However, if smearing occurs, it is recommended to switch to a spray sealer or find an alternative brush-on sealer that does not cause smearing.
By following these steps and being cautious about the potential for smearing, you can ensure that your painted rocks remain beautiful and well-preserved.

Paint-on sealers are applied with a bristle or sponge paintbrush
Sealing painted rocks is a great way to protect your artwork from the elements and ensure it stands the test of time. Paint-on sealers are an excellent option for this, offering precise application and economic benefits.
Paint-on sealers, as the name suggests, are applied with a brush directly over your painted design. You can use a bristle or sponge paintbrush to apply a thin layer of the sealer. This method allows for greater control over where the sealer is applied compared to pour-on or spray-on alternatives. It also tends to be more cost-effective, as a little sealer goes a long way.
When using a paint-on sealer, it's important to start with a light coat, building up the layers gradually. This helps prevent smudging or running of the paint. A nice thin coat first, followed by a heavier coat at an angle to hit the sides of the rock, ensures complete coverage.
Paint-on sealers come in various brands and finishes, so you can choose the one that best suits your needs. A popular brand is Mod Podge, which offers some water resistance. However, for outdoor rocks, consider Mod Podge Outdoors, designed to withstand the elements. Other brands to look out for include Micador, Dulax, and Boyle, which offer different finishes like matte, glossy, or satin.
While paint-on sealers provide precision and economic benefits, they may not be suitable for all types of paint. For example, some users have reported that paint-on sealers can cause Uni Posca Paint Pens to smear and run. In such cases, a spray sealer is recommended first, followed by a paint-on sealer for added protection and decorative effects.

Spray sealers are available in different finishes like glossy and matte
Spray sealers are a popular choice for sealing painted rocks. They are available in different finishes, such as glossy and matte, allowing you to customise the look of your rocks. Spray sealers are easy to use and provide great coverage. They are also economical, as a little product goes a long way.
When using a spray sealer, it is important to follow a few key steps to ensure the best results. Firstly, always ensure your painted rocks are completely dry before applying any sealer. This is crucial, as applying sealer to wet paint can cause it to run or smear. It is recommended to wait at least 24 hours to ensure the paint is fully cured.
Once your rock is dry, you can begin applying the spray sealer. Hold the can at least 8 inches away from the rock to ensure an even coat. Start with a light mist coat, and then build up with additional coats as needed. Be careful not to oversaturate the rock, as this can cause dripping or running.
Spray sealers are a versatile option, suitable for various types of paint, including acrylics and paint pens. They are also a good choice for sealing temporary tattoos applied to rocks, as the tattoos are typically water-soluble and require proper sealing.
When choosing a spray sealer, consider the finish you desire. A glossy finish will give your rocks a shiny, vibrant look, while a matte finish will result in a more subdued, elegant appearance. You can also find spray sealers with a satin finish for a subtle sheen.
Popular brands of spray sealers include Krylon and Rust-Oleum, which can be found at your local craft store, hardware store, or online. Always be mindful of the strong fumes that spray sealers produce and use them in a well-ventilated area or outdoors.

Sealing painted rocks is a great way to protect your artwork and ensure it stays beautiful for longer. There are various types of sealers available, but for rocks painted with acrylic paint, a spray sealer is the best option.
Spray sealers are easy to use and provide great coverage. They are also versatile, as they can be used on rocks with different types of paint, including paint pens and 3D paints.

Before applying a spray sealer, it is important to let your painted rocks dry completely. Place your rocks on a surface with enough space to spray them from different angles. When you are ready to seal the rocks, hold the spray can at least 8 inches away from the rock and start with a light mist coat to avoid drips and runs. You can then build up the coat thickness gradually.
If you are sealing rocks with Sharpies or Posca paint pens, it is recommended to use a brush-on sealer like Mod Podge first, followed by a spray sealer. This will prevent the ink from smearing or running.
By following these steps and using a spray sealer, you can effectively seal your acrylic-painted rocks, ensuring they are protected from the elements and maintain their vibrant colours.

Frequently asked questions
Sealing painted rocks helps to preserve the artwork and protect it from the sun, rain and the passage of time. There are different types of sealants available, such as paint-on, pour-on, or spray-on. Spray sealants are the most popular and easily available option.
Before using a spray sealant, ensure that the painted rocks are completely dry. Hold the spray can at least 8 inches away from the rock and start with a light mist coat. Once that coat dries, spray a heavier coat at an angle to hit the sides of the rock. Rotate the rock to ensure that all sides are covered.
Similar to spray sealants, brush-on sealants should be applied in thin coats first. Once the first coat dries, apply a heavier coat.
Spray sealants are recommended for rocks painted with Posca pens as brush-on sealants may cause the paint to smear and run.
If the tattoo has a metallic finish, apply a coat of Mod Podge first. Once it dries, apply a spray sealant. If the tattoo does not have a metallic finish, you can skip the Mod Podge and directly use a spray sealant.
