Dry-erase paint is a great way to add functionality to your office or classroom walls. It can transform any smooth surface into a writable area. However, it is important to consider the number of coats required for the paint to function optimally. While most dry-erase coating companies advise applying two layers of their products, there are some high-end brands that claim to provide the same results with just one coat. In exceptional cases, a second coat of dry-erase paint may be needed, for instance, if certain areas were missed during the initial application, or if the first coat was written on before it dried completely.
| Characteristics | Values |
|---|---|
| Number of coats | 2 coats are recommended by many dry-erase coating companies to achieve optimal results, but some products only require 1 coat. |
| Reasons for 2 coats | To ensure complete coverage, opacity, and a uniform colour. To make the surface long-lasting, easily writable with dry-erase markers, and erasable with standard erasers or cloths. |
| Reasons for 1 coat | Some high-end products only require 1 coat to achieve the same results as 2 coats of other brands. |
| Exceptional cases for a second coat | If areas were missed during the initial application, if the coating was too thin, if permanent marker was used on the surface, or if the first coat was written on before it dried. |
| Waiting period between coats | At least 24 hours. |
| Surface preparation | The surface must be perfectly smooth before applying paint. Any scratches or bumps should be repaired, and the surface should be sanded and cleaned with a dry cloth. |
| Base coat/primer | A base coat or primer is recommended to prevent bubbling and other issues. Some products do not require a primer. |
| Dry time | Dry-erase paint typically takes 5-8 hours to be touch dry and 1-7 days to be ready for use. |
| Ease of application | Dry-erase paint is generally easy to apply and can be applied by anyone. |
| Safety | Some dry-erase paints are safe to apply around adults and children due to low VOC and low odour. |
| Certifications | Some dry-erase paints have certifications such as LEED, Fire, Indoor Air Comfort, and M1. |
| Durability | Dry-erase coatings can last for 10+ years with proper care and maintenance. |
| Eco-friendliness | Some dry-erase paints are eco-friendly and have certifications to support their claims. |

What You'll Learn
Dry-erase paint application
Dry-erase paint can be applied to almost any smooth surface, including drywall, wood, glass, laminate, and metal. It is a great way to add functionality to your office or classroom walls, allowing you to transform any smooth surface into a writable area.
Before applying dry-erase paint, it is important to prepare and prime the surface. The surface should be perfectly smooth, and any scratches or bumps should be repaired. Spackle can be used to fill in any irregularities, and then sanded to create a uniform surface. A suitable base paint or primer should also be applied, such as a water-based enamel with a satin or eggshell sheen. It is important to follow the manufacturer's instructions, as some dry-erase paints may not require a primer.
Once the surface is prepared, you can apply the dry-erase paint. Some brands of dry-erase paint require two coats to achieve the best results, namely a long-lasting surface that is easily written on and erased. However, other brands, such as ReMARKable dry erase paint, only require one coat to create a highly resilient and easily writable surface. It is important to note that if you are using a two-coat system, you may need to wait at least 24 hours between the application of the first and second coats.
After applying the paint, it will typically take around 5 to 8 hours to dry to the touch. However, it is recommended to wait at least 48 hours to 7 days before writing or drawing on the surface to ensure optimal performance.

Optimal surface preparation
A suitable base paint or primer should be applied to the surface before applying dry-erase paint. Some dry-erase paints, such as ReMARKable, have their own tintable base coat/primer, which is specifically formulated for use with their clear and white varieties of whiteboard paint. A water-based enamel with a satin or eggshell sheen can also be used as a base coat. If the wall finish is matte or flat, a clear primer should be applied and allowed to dry for 24 hours.
When using a high-gloss dry-erase paint, such as IdeaPaint Clear, a base coat paint with a semi-gloss or gloss finish is recommended. If the wall is a deep tint, or if the sheen is unknown, two coats of 100% acrylic topcoat paint should be applied, allowing 24 hours of drying time before applying the dry-erase paint.
It is important to note that dry-erase paint should not be applied over an epoxy-based coating, as this can cause yellowing, cracking, and a strong odour.

Primer and base coat
When applying dry-erase paint, it is important to prepare the surface properly to ensure the best results. The surface should be smooth, with any scratches, bumps, or irregularities filled and sanded down. This can be achieved by using spackle, drywall mud, or a similar compound, followed by sanding with fine-grit sandpaper (around 240-grit). It is especially important to avoid "orange peel walls", which have a rough texture that will need to be smoothed out before applying dry-erase paint.
Once the surface is smooth, the next step is to apply a primer and base coat. A primer is important because it helps the dry-erase paint adhere better to the surface and can improve the durability and longevity of the finish. It is recommended to use a high-quality primer specifically designed for use with dry-erase paint, such as the ReMARKable tintable base coat/primer or one of the preferred primers listed by IdeaPaint, including IdeaPaint Clear Primer, Zinsser BIN Clear Primer, or Kilz Klear Primer. The primer should be allowed to dry completely before proceeding to the next step, which typically takes around 24 hours.
When choosing a base coat, it is important to select a product that is compatible with the dry-erase paint you are using. Some dry-erase paints, such as IdeaPaint CREATE Clear and Crayola Take Note! Clear, perform best over a latex base coat with an eggshell, satin, semi-gloss, or gloss finish. If the surface has a matte or flat finish, a clear primer should be applied first, followed by a coat of the recommended base coat. The base coat should also be allowed to dry completely, following the manufacturer's instructions, before applying the dry-erase paint.
In some cases, a second coat of primer or base coat may be necessary, especially if the first coat is too thin or uneven. However, it is important to follow the specific instructions provided by the manufacturer of your chosen products, as different brands may have varying requirements for primer and base coats. Additionally, it is worth noting that some high-end dry-erase coatings, such as ReMARKable, claim to only require one coat of their product to achieve optimal results, eliminating the need for multiple coats of primer, base coat, and dry-erase paint.
Overall, by taking the time to properly prepare your surface with a suitable primer and base coat, you can ensure that your dry-erase paint application is successful and long-lasting.

Number of coats
The number of coats of dry-erase paint you need to apply depends on the specific product and the surface you are painting. Some products, such as ReMARKable dry erase paint, only require one coat to create a highly resilient, impermeable, and easily writable surface. Other brands of dry-erase coatings generally require two coats to achieve the same results.
It is important to prepare the surface before applying any type of dry-erase paint. This includes filling any holes or imperfections and sanding the surface to create a smooth finish. A suitable base coat or primer should also be applied, especially if you are using a low-end whiteboard paint, which may require a longer drying time.
The manufacturer's instructions should always be followed when applying dry-erase paint. Some products may require a specific number of coats, while others may recommend a minimum or maximum number of coats depending on the surface and the desired results.
In general, two coats of dry-erase paint are usually recommended to obtain optimal results. This is similar to standard types of paint, such as interior and exterior latex house paint, which typically require two coats to achieve a completely opaque, uniformly coloured, durable, and cleanable surface.
However, there are exceptions where a second coat of dry-erase paint may be needed. For example, if certain areas were missed or the coating was applied too thinly during the initial application, if someone wrote on the coated surface with a permanent marker, or if the first coat was not given enough time to dry thoroughly before use.

Drying time
The drying time of dry-erase paint varies depending on the brand and type of paint. Some dry-erase paints can take up to seven days to dry completely, while others may dry within 24 hours or even less. For example, ReMARKable dry erase paint is known for its rapid drying time, allowing users to have a usable whiteboard surface in as little as one business day. Similarly, Smart Whiteboard Paint is advertised as being touch-dry in 5 hours and ready to use in 7 days.
The drying time can also depend on the type of surface being painted and the number of coats applied. For instance, applying dry-erase paint over a base coat or primer may require a longer drying time. Some primers or base coats can take up to 24 hours to dry before the dry-erase paint can be applied. Additionally, multiple coats of dry-erase paint may be necessary for certain brands, which will extend the overall drying time.
It is important to follow the manufacturer's instructions for drying times, as they can vary. Some paints may require a longer waiting period between coats, such as 24 hours or more. In some cases, a second coat of dry-erase paint may be needed if the first coat was not allowed to dry thoroughly before use.
To ensure the best results, it is recommended to prepare and prime the surface properly before applying dry-erase paint. This includes repairing any scratches or bumps and sanding the surface to create a smooth finish. Following these steps will help create a high-quality, long-lasting dry-erase surface.
Additionally, the environmental conditions can also affect the drying time. Proper ventilation is important, and factors such as humidity and temperature can influence how quickly the paint dries. Therefore, it is always advisable to refer to the manufacturer's guidelines and recommendations for specific drying times and application instructions.
