Chalk paint is a popular and versatile medium for DIY projects. It is easy to work with, requires minimal prep work and is perfect for achieving a shabby chic look. However, if you’re planning on using chalk paint on outdoor projects, such as garden furniture or decorative signs, it is important to seal it properly to protect it from the elements.
In this blog post, we’ll dive into the details of how to seal chalk paint for outdoor use, including step-by-step instructions, product recommendations and frequently asked questions.
How to Seal Chalk Paint for Outdoor Use
When it comes to sealing chalk paint for outdoor use, there are a few options to choose from. The most popular methods are:
Wax is a traditional and simple way to seal chalk paint. It provides a soft sheen and can be buffed to create a subtle shine. However, wax is not the best option for outdoor projects as it is not very durable and can melt or fade in the sun.
To apply wax, simply use a brush or cloth to apply a thin layer over your unsealed chalk paint. Work in small sections and remove any excess wax with a clean cloth. Allow the wax to dry for at least 24 hours before using your project.
Polyurethane is a clear, water-resistant sealant that provides a hard, protective coating over your chalk paint. It is a great option for outdoor projects as it is durable and long-lasting.
To apply polyurethane, use a brush or roller to apply a thin, even layer over your chalk paint. Allow the first coat to dry for at least 2-4 hours before applying a second coat. For best results, use a high-quality polyurethane that is specifically designed for outdoor use.
Polycrylic is a water-based sealant that provides a protective coating over your chalk paint. It dries quickly and doesn’t yellow over time, making it a popular choice for white or light-colored projects.
To apply polycrylic, use a brush or roller to apply a thin layer over your chalk paint. Allow the first coat to dry for at least 2-4 hours before applying a second coat. For best results, choose a polycrylic that is specifically designed for outdoor use.
