What You'll Learn
The number of coats depends on the paint type
The number of coats you will need to apply when using Rust-Oleum Chalked Paint depends on the type of paint you are using. For instance, Rust-Oleum Specialty Dry Erase Paint requires a couple of coats to convert a wall into a functional calendar. However, one user on Sarah Joy's blog states that Rust-Oleum Chalked Paint needs more coats to achieve decent coverage compared to Annie Sloan Chalk Paint. The user also mentions that Annie Sloan paint covers well and is very durable, whereas Rust-Oleum paint is not as good and requires more coats.
On the other hand, another user on the same blog disagrees, stating that Rust-Oleum paint is just as good as Annie Sloan paint but at a more affordable price point. This user dilutes the Annie Sloan paint with water but does not dilute the Rust-Oleum paint for their comparison.
In terms of application, Rust-Oleum recommends using a good-quality synthetic brush or a 1/4" to 3/8" nap roller or foam roller to apply their Clear Chalkboard Paint. Light, even strokes should be used to ensure an even and smooth finish. The paint dries to the touch in 30 minutes, can be handled in 2 hours, and is fully dry in 2-4 hours. It can be recoated after 4 hours and should be allowed to cure for three days before being used as a writable surface.
When applying Rust-Oleum Chalkboard Paint to a wall, one user on DoItYourself.com mentions that they followed the instructions exactly, including using a high-density foam roller, but the paint went on very thin and bubbled up. They then tried a fibre roller, which performed better and gave the wall a chalkboard-like appearance. However, the overlap strokes built up and were visibly thicker, leading the user to consider sanding down the high spots before applying a second coat. Another user on the same forum suggests that lap marks and ridges can be sanded down if they can be felt, and if they are just visible, another coat or two should make them go away.

Chalkboard paint application methods
When applying chalkboard paint, it is important to prepare the surface correctly to ensure a durable finish. The process is similar to painting with regular paint, but there are some key differences. Firstly, ensure you have enough paint for your project, as chalkboard paint must be applied in one go to keep the colour consistent. Clean the surface with a damp rag and lightly sand it with fine sandpaper until it is smooth to the touch. Use a putty knife to fill in any cracks or holes with drywall filler, wood putty, or another suitable filler. Wait for the filler to dry, then sand and wipe away the dust.
Before painting, gently stir the paint with a brush. Avoid stirring too vigorously, as chalkboard paint is susceptible to breaking down, which will affect the final finish. Start painting in the middle of the surface and work outwards, using a roller for large areas and brushes for smaller areas. Maintain consistent brush strokes and overlap all brush marks for a smooth finish. Clean up any drips as you go.
Allow the paint to dry for 2-3 hours before applying another coat. Chalkboard paint typically requires 2-3 coats for the best results, and some colours may need an extra coat. Red colours, for example, often need three coats, starting from a clean white background. After applying the final coat, leave the paint to dry for 48 hours before use.
Once the paint is dry, rub chalk over the entire surface and leave it for a few seconds before erasing. This will prepare your chalkboard for use. Chalkboard paint can be applied to a variety of surfaces, including walls, glass, cabinets, and clay pots. However, it is important to note that the smoother the surface, the easier it will be to clean. For exterior use, seal the wood as much as possible before applying the chalkboard paint.

The importance of sanding between coats
While there is no explicit mention of the number of coats required for Rustoleum Chalkboard Paint, it is clear that multiple coats are necessary for the best results. A user has mentioned that they "primed [their] piece, have one coat on and plan on 2 more." This indicates that at least three coats are needed for adequate coverage.
When applying multiple coats of paint, it is essential to sand between coats to ensure a smooth and professional finish. Sanding between coats of Rustoleum Chalkboard Paint is particularly important because of the paint's thin consistency. One user has commented that "if you're not doing a light sand between coats, you're really not going to get a smooth finish."
Sanding between coats helps to create an even and consistent surface by removing any imperfections or thick areas of paint. It also improves the adhesion of the subsequent coat, allowing it to bond more effectively with the previous layer. This results in a stronger and more durable finish that is less likely to chip or peel over time.
Additionally, sanding between coats can help to create a smoother surface for writing and drawing on the chalkboard. By removing any bumps or unevenness, the chalk will glide more smoothly across the surface, improving the overall writing and drawing experience.
It is important to note that the sanding process should be done lightly and with the appropriate grit sandpaper to avoid damaging the previous coat of paint. After sanding, it is crucial to ensure that the surface is clean and dust-free before applying the next coat of paint.

The best tools for application
When applying Rust-Oleum Chalkboard Paint, it is important to use the right tools to ensure a smooth and even finish. The paint can be applied with a brush or a roller, and there are a few options available for each method.
If you prefer to use a brush, it is recommended to opt for a good-quality synthetic brush. Avoid cheap paintbrushes, as these may shed bristles that can get lodged in the paint. A high-quality brush will ensure that the paint is applied smoothly and evenly, without leaving brushstrokes or bristles behind.
For roller application, Rust-Oleum recommends using a foam roller with a 1/4" to 3/8" nap. Foam rollers are widely available and affordable, making them a popular choice for this type of paint. However, some users have reported mixed results with foam rollers, with reports of thin coverage, bubbling, and a glossy finish. To avoid these issues, consider using a fibre roller instead, which can provide better coverage and a more authentic chalkboard-like texture. Alternatively, a short-nap roller cover may also give you the coverage you desire.
Regardless of the application method you choose, it is important to follow the manufacturer's instructions and allow the paint to dry and cure properly. Before using the surface as a chalkboard, remember to condition it by rubbing chalk over the entire surface and then erasing it. This will ensure the best writing and erasing experience.

Paint drying and curing times
When using Rustoleum Chalkboard Paint, it is important to understand the difference between paint drying and curing times. While chalk paint may feel dry to the touch within 30 minutes, it is recommended to wait a couple of hours before applying a second coat to avoid pulling off the first layer of paint. Environmental factors, such as humidity and temperature, can also affect the drying time.
Chalk paint is known for its quick-drying properties, usually drying to the touch within minutes. However, it is important to distinguish between surface dryness and complete dryness. Even though the paint may feel dry on the surface, it can take a couple of hours for the paint to dry completely before applying another coat.
To achieve the best results with Rustoleum Chalkboard Paint, it is recommended to apply a generous first coat without over-brushing or stretching the paint. This technique ensures adequate coverage and reduces the need for multiple coats. Allowing the paint to dry completely between coats is crucial to avoid any mess or paint pulling.
Additionally, curing time refers to the period it takes for the paint to be fully adhered to the surface and reach its maximum hardness. Unlike drying, curing can take significantly longer, even up to two weeks. During this time, the painted surface should be handled with care to avoid any accidental damage or paint scraping.
To summarize, when working with Rustoleum Chalkboard Paint, allow sufficient drying time between coats by following the specific instructions provided by the manufacturer. This will ensure a smooth and successful painting experience, resulting in a durable and aesthetically pleasing finish.
