Sealing chalk paint with wax to protect and preserve
Sealing chalk paint with wax is a great way to protect and preserve your paintwork. Wax not only protects your finish but also helps the colour last longer. It creates a strong, durable finish that can withstand normal wear and tear.
Chalk paint is a decorative paint with terrific sticking power and can be applied to most surfaces. However, it does need protection to withstand general wear and tear. Chalk Paint® Wax was developed together with Chalk Paint® to create a beautiful, long-lasting finish. Applying a coat of clear wax over chalk paint will deepen the colour of the paint and create a matt finish. It will also protect against fingermarks and stains.
To seal chalk paint with wax, first, make sure your paint is completely dry. Then, using a brush or cloth, apply the wax in large areas without too much pressure. The wax will lightly darken the paint, so check for any areas that are still paler and apply more wax as needed. If you want a matt finish, you can leave the wax as is. If you prefer a more shiny look, you can buff your finish the day after waxing to create a glossy sheen. Use a rag or polishing cloth and rub it over the surface in circular motions.
While Chalk Paint® Wax will be dry to the touch within 24 hours, it can take up to 2 weeks to fully cure and harden. During this time, you can use the piece with a little caution. Once fully cured, your waxed finish should last a very long time. If any areas of wax start to thin over time, simply re-wax and leave to cure again.
Chalk Paint® Wax offers enough protection for most applications. However, for projects that need extra protection, such as flooring, skirting boards, or outdoor furniture, you may want to use a polyacrylic varnish like Chalk Paint® Lacquer. Lacquer will completely seal your piece so no water can get in and damage your paintwork.

Using lacquer to seal chalk paint
Sealing chalk paint is important to protect your paintwork and ensure that your hard work does not go to waste. Lacquer is a great option to seal chalk paint, especially if your painted item will be subjected to daily wear and tear, or if it will be touched and cleaned frequently. Here is a step-by-step guide to using lacquer to seal chalk paint:
Prepare the Lacquer:
Stir the chalk paint lacquer well before starting and continue stirring regularly during use. The good stuff tends to sink to the bottom, so make sure it is well mixed. If you prefer a more matte look, choose a matt lacquer. For an even stronger finish, go for a gloss lacquer.
Apply the First Coat:
Use a brush or roller to apply a thin coat of lacquer to your painted surface. Work methodically to ensure that every part of the surface is coated. You can dilute the lacquer with 10% water to help it go on more evenly. Allow the first coat to dry for 1-2 hours, depending on the climate.
Apply the Second Coat:
For added durability, apply a second thin coat of lacquer in the same manner as the first. Make sure to seal your piece completely so that no water can get in and damage the paintwork. Allow the second coat to dry before using the item.
Buffing (Optional):
If you prefer a more shiny look, you can buff your finish the day after applying the lacquer. Use a rag or polishing cloth and rub it over the surface in circular motions to create a glossy sheen.
Curing:
The finish will be fully cured within 2 weeks. Once fully cured, your lacquered finish will be long-lasting and will withstand normal wear and tear.
By following these steps, you can effectively seal chalk paint using lacquer. Remember to consider the desired finish and level of protection before starting, as this will impact the type of lacquer you choose and the number of coats you apply.

Applying a sealant to protect from sun damage
Chalk paint is a popular choice for home decor, but it is a little more fragile than acrylic or latex-based paints and can be prone to chipping and staining. To prevent this, a sealant can be applied.
The sealant you choose will depend on the desired finish and the location of the painted piece. If you want a matte finish, you can use a wax sealant. Wax will give your surface a smooth, satiny finish and can be buffed to a subtle sheen. It does take a little more work to apply than other sealants, and it may need to be reapplied periodically. If you want a high-shine finish, you can use a lacquer or varnish.
If your painted piece will be kept outdoors and exposed to sunlight, it is important to choose a sealant that will protect it from sun damage. Polyurethane is a durable topcoat that can be applied with a brush or spray, but it has a strong odor and tends to yellow over time, even when used on indoor furniture. Polycrylic is another option, which provides a hard finish and is water-based, so it goes well over acrylics. It cures to a smooth surface and can be easily cleaned with a damp cloth.
If you are sealing chalk paint on plastic, there are a few options. You can use a wax sealant, such as Fiddes Supreme Wax Polish, or a lacquer or varnish. If you want a matte finish, you can use a clear spray paint or a matte topcoat.

Sealing chalk paint with polycrylics
Sealing chalk paint is important to protect your paintwork and ensure that your hard work does not go to waste. Polycrylic sealants are the most durable choice for sealing chalk paint and are very resistant to scratches and scuffing. They are ideal for chalk-painted surfaces that will be handled frequently or come into contact with other objects.
Polycrylic sealants are sold in cans, similar to paint. Before applying, it is important to stir the sealant thoroughly and ensure that your surface is clean and dry. Apply the sealant with a paintbrush, moving in one direction, and ensure that it gets into any small spaces. Apply a thin coat of the sealant and let it cure fully before applying a second coat. The curing time will vary depending on the brand, so always check the label.
It is important to note that not all polycrylics are compatible with chalk paint. Some products labelled as "polyurethane" or "oil-based" can cause white chalk paint to turn yellow. Water-based polycrylics may also have this effect. Therefore, it is recommended to test the polycrylic on a small area first before proceeding with the sealing process.
If you are looking for a sealant that will preserve the smooth, chalky look of your unsealed chalk paint, opt for a matte finish. A satin finish will also provide a similar look to furniture wax but with less effort.

Using oil to seal chalk paint
While oil can be used to seal chalk paint, it is not the most popular option. Chalk paint is a popular choice for decorating indoor and outdoor furniture, walls, ceilings, and even floors. It is eco-friendly, with low volatile organic compounds (VOCs) and virtually no smell.
Chalk paint can be sealed with wax, lacquer, varnish, glaze, or oil. Wax is a popular choice as it is designed to nourish and protect wood and can be applied over any finish. It can also be buffed to create a glossy sheen. Lacquer and varnish are also common options, providing a protective layer to the paintwork and helping the colour last longer. Glaze is a liquid product that is applied and then wiped off to achieve an aged look.
Oils are more commonly used with milk paint but can also be used with chalk paint. Oil-based sealants tend to yellow over time, so it is not often used, especially over light-coloured paint. However, if you are using black chalk paint, an oil-based poly can be a good option as you won't notice the yellowing. Fusion Mineral Paint's "Stain and Finishing Oil" is a durable and easy-to-apply option that won't leave a cloudy finish.
