What You'll Learn
Preparing the glass surface
Start by lightly sanding the glass surface with fine-grain sandpaper. This step is important as it helps improve the adhesion of the paint to the glass. Make sure to sand evenly across the surface, creating a uniform texture. After sanding, it is essential to wipe the glass surface clean using a tack cloth. This will remove any dust or residue left from the sanding process, ensuring a smooth base for the paint to adhere to.
The next step is to apply a primer to the glass surface. Priming is crucial as it helps the paint adhere better and creates a more durable finish. Krylon offers a variety of primers, such as the Krylon Fusion All-In-One®, which is specifically designed for no-prep, one-step application. After applying the primer, you will notice that the glass will become opaque. This is a normal part of the process, and it indicates that the primer is doing its job.
Once the primer is dry, you can proceed with the painting process. Remember to follow the specific instructions on your chosen Krylon paint product for the best results. By taking the time to properly prepare the glass surface, you can achieve a professional and long-lasting finish for your project.

Using the right paint
Krylon offers a range of products suitable for painting on glass, including the Fusion All-In-One, which is a paint-and-primer in one that can be used on glass, and specially formulated paints that give clear glass a frosted or mirrored finish.
Krylon's Stained Glass Paint, for example, can add a colourful touch to any glass surface. It is important to prepare the glass before spray painting. Lightly sand the glass with fine-grain sandpaper to improve adhesion, then wipe it clean with a tack cloth. The glass will become opaque after you apply the primer.
Krylon's Looking Glass Paint is another option. It transforms clear glass into a highly reflective, mirror-like surface with a durable finish.
If you are looking for a paint that can be used on multiple surfaces, Krylon Fusion All-In-One is a good option. It is a no-prep, super-bonding paint with 5X stronger adhesion that can be used on glass, plastic, vinyl, and other surfaces. It provides a long-lasting finish and protects against rust, UV fading, and weather damage.
Most Krylon spray paints are dry to the touch in 20 to 25 minutes and ready to handle in about an hour. Be sure to wait the recommended amount of time between coats for a smooth, quality finish.

Spraying technique
Before spraying, prepare the glass surface by lightly sanding it with fine-grain sandpaper. This will improve the paint's adhesion. Then, wipe the glass clean with a tack cloth. You can also apply a primer at this stage, turning the glass opaque.
When you're ready to start spraying, wear eye protection and ensure you are in a well-ventilated area. Krylon spray paint cans feature unique nozzles that are easy to push, allowing you to spray at any angle, even upside down, to reach tight spots or coat wide areas. To spray wide areas, turn the tip of the nozzle horizontally or diagonally, and for narrow areas, turn it vertically.
For the best results, hold the can 10-16 inches away from the glass surface and spray using a steady back-and-forth motion, slightly overlapping each stroke. Be sure to keep the can in motion while spraying to avoid drips and an uneven finish.
If your project requires multiple coats of paint, be sure to follow the recommended dry times between coats. Most Krylon spray paints are dry to the touch in 20-25 minutes and can be handled after about an hour. To prevent the nozzle from clogging, turn the spray can upside down, wearing eye protection, and press the nozzle for 5 seconds until clear gas is discharged.

Drying time
When using Krylon paint on glass, it is important to allow adequate drying time between coats. The general recommendation is to wait at least 15 minutes between each coat. This gives the paint a chance to dry sufficiently before applying the next layer. However, the drying time can vary depending on the type of Krylon paint you are using. For example, the Krylon Fusion All-In-One spray paint, which is specifically designed for use on glass, recommends a longer drying time of 24 hours between coats.
Temperature and humidity play a crucial role in the drying time of Krylon paint on glass. In ideal conditions, with moderate temperature and low humidity, the paint may dry faster. A warm, dry environment is generally recommended to speed up the drying process. However, be cautious not to expose the painted glass to extremely high temperatures, as it can affect the curing process and the overall finish.
The number of coats you apply will also impact the drying time. For best results, plan to apply several thin coats rather than a single thick coat. Thin coats dry faster and reduce the risk of dripping or running. Allow sufficient time for each coat to dry before applying the next one. Depending on the project and the desired opacity, you may need anywhere from 2 to 4 or more thin coats of paint.
Once you have completed your final coat, allow for an extended drying time before handling the painted glass. This is especially important if you intend to use the glass item functionally, such as a drinking glass or vase. The recommended curing time for Krylon paint on glass is typically 72 hours or more. This extended drying time ensures that the paint is fully cured, providing a durable and long-lasting finish.
It is worth noting that factors such as humidity, temperature, and air circulation can affect the drying time. In high-humidity environments, the paint may take longer to dry, and it is advisable to provide additional time between coats. Proper ventilation and a dust-free environment are also crucial to ensure that the paint dries properly and that the finish is smooth and uninterrupted.
By following these guidelines and allowing adequate drying time, you can ensure that your Krylon paint job on glass turns out beautifully and lasts for a long time. Remember to always refer to the specific instructions provided by the manufacturer on the paint can, as drying times may vary slightly between different products within the Krylon range.

Aftercare and maintenance
Cleaning and Preparation:
Before painting, it is essential to clean the glass surface thoroughly. Use a monitor wipe or a clean cloth to remove any dust or debris. This step ensures that the paint adheres smoothly and evenly. For optimal results, you can lightly sand the glass with fine-grain sandpaper to enhance adhesion. Don't forget to wipe away any residue with a tack cloth after sanding.
Priming and Painting:
Priming the glass surface is crucial before applying Krylon spray paint. Choose a well-ventilated workspace and cover the area with a drop cloth or tarp to catch any paint overspray. Place your glass item on the covered surface and use a primer specifically designed for glass to ensure the paint adheres properly. Remember to follow the manufacturer's instructions for the primer and allow adequate time for it to dry before proceeding to paint.
Painting Technique:
Hold the Krylon spray paint can 8 to 10 inches away from the glass surface. Spray in a sweeping, side-to-side motion with slight overlap to ensure even coverage. It is generally recommended to apply multiple thin coats of paint, allowing about 1 minute of drying time between each coat. This technique results in a smoother and more durable finish.
Drying and Handling:
Allow your painted glass item to dry completely before handling it. Most Krylon spray paints are dry to the touch within 20 to 25 minutes, but it is best to wait at least an hour before touching or moving your painted glass item. For multiple coats, always follow the manufacturer's recommended dry and recoat times.
Avoiding Clogged Nozzles:
To prevent the spray can nozzle from clogging, perform regular nozzle maintenance. Wear eye protection and turn the spray can upside down. Press the spray nozzle for 5 seconds or until you see clear gas being discharged. Use a regionally compliant cleaner to wipe off any remaining residue on the nozzle. This process ensures that the nozzle is clear and will not clog, guaranteeing the performance of your Krylon spray paint.
Storage:
Proper storage is essential to maintain the condition of your painted glass items. Keep them in a safe area, away from direct sunlight or extreme temperatures. Avoid placing heavy objects on top of your painted glass, as this may scratch or damage the finish. With the proper aftercare and maintenance, your painted glass creations will retain their beauty and serve as unique decorative pieces for years to come.
