Milk paint can be made to stick to plastic with the addition of a bonding agent
Milk paint is typically used on porous surfaces such as raw wood, unprimed drywall, concrete, brick, and terracotta. However, with the addition of a bonding agent, milk paint can be made to stick to plastic and other non-porous surfaces.
A bonding agent, such as Ultra Bond or MilkGrip, can be mixed with milk paint to help it adhere to challenging surfaces like plastic, glass, metal, and varnished items. These bonding agents are water-based, concentrated acrylic emulsions that can be combined with milk paint or used as a primer. They are also non-toxic and almost odourless.
To use a bonding agent with milk paint, it is recommended to mix one part bonding agent with four parts milk paint. For an even stronger grip, equal parts of each can be combined. It is important to note that the ratios of bonding agent can be adjusted depending on the type of surface. The bonding agent should be mixed with all coats of paint for optimum adhesion.
Before applying milk paint with a bonding agent to plastic, it is crucial to properly prepare the surface. The plastic surface must be clean without any wax or silicone. It is recommended to clean the surface with Tri-Sodium Phosphate and scuff it with sandpaper to create a rough surface for better paint adhesion. Always test the adhesion on a small area before proceeding with a full application.
By following these steps and adding a bonding agent to milk paint, you can successfully make milk paint stick to plastic and other non-porous surfaces.

Prepping the surface is the most important step to ensure paint sticks to plastic
If you are painting plastic, it is important to wash, sand, and prime the surface. First, scrub the plastic piece with soapy water and a sponge. Rinse the piece and let it dry completely. Next, use a fine-grit sanding block to rub the entire surface. The idea is to roughen up the surface a little so the paint has some texture and more surface area to cling to. Once you are done sanding, wipe the plastic with a paper towel or microfiber rag to ensure that any dust or debris is removed.
If the plastic is new, wipe it down with paint thinner for the best results. If the plastic has a glossy finish, lightly sand it and remove dust with a tack cloth. If the plastic has set-in stains, pour rubbing alcohol onto the stain, let it sit for 10 to 20 minutes, and then scrub it away. You can also use an ammonia-based cleaner or an adhesion promoter to wipe down the plastic and get rid of any silicones.
Once you are done prepping the surface, you can start painting the plastic. Use spray paint that is specifically made for plastic. Hold the canister 6 to 8 inches away from the plastic and spray in thin, even layers. Let it dry completely before adding a second coat.

Milk paint is best applied to porous surfaces like raw wood, unprimed drywall, concrete, and brick
Milk paint is a versatile paint that can be used on a variety of surfaces, but it is best applied to porous surfaces. These porous surfaces include raw wood, unprimed drywall, concrete, and brick, as well as other materials like terra cotta, unglazed tile, and cinder blocks. The paint can be applied to these surfaces without the need for a primer or a bond coat, making it a convenient option for many projects.
Raw wood is an excellent surface for milk paint as it absorbs the paint well and creates a beautiful finish. The paint can be applied directly to the wood, or you can choose to add a bonding agent to enhance its adhesion. When using milk paint on raw wood, it is important to consider the type of wood and its condition. For example, if you are using plywood, which is not truly raw wood due to its composite nature, you may need to apply a bond or prep the surface before painting. Additionally, if the wood is particularly knotty, it is recommended to use an outdoor additive to prevent the knots from showing through the paint.
Unprimed drywall is another porous surface that milk paint can be applied to. However, it is important to note that achieving an even finish on drywall can be challenging. The SafePaint formula is specifically designed for use on drywall and can help improve the evenness of the paint application. When using milk paint on drywall, it is recommended to test the paint on a small area first to ensure that it adheres properly.
Concrete and brick are also ideal surfaces for milk paint as they are naturally porous. The paint can be easily applied to these surfaces and will create a strong bond. Additionally, milk paint can be sealed with a finishing oil, cream, or wax to provide extra protection and enhance its durability. This is especially important for exterior applications, as sealing the paint will provide better resistance to the elements.
While milk paint is typically applied to porous surfaces, it can also be used on non-porous surfaces with the addition of a bonding agent or Ultra Bond. This allows the paint to adhere to surfaces such as plastic, metal, glass, and latex paint. Proper preparation of the surface is crucial when using milk paint on non-porous materials to ensure the best results.

Milk paint will achieve the strongest bond when applied fresh
Milk paint is a versatile and safe paint option that can be used on a variety of surfaces. It is made from natural ingredients and is even safe for children's toys and furniture. While milk paint can be applied to a range of surfaces, it is important to note that it will achieve the strongest bond when applied fresh. Here are some key points to consider when using milk paint and ensuring a strong bond:
Fresh Milk Paint Application
Freshly mixed milk paint will result in the strongest adhesion to your desired surface. Milk paint has an extensive shelf life in its dry powder form, lasting three years or more. However, once mixed, it is best used immediately to achieve optimal results. If stored in a sealed container, milk paint can last for about two weeks to a month.
Surface Preparation
Proper surface preparation is crucial for a strong bond. Ensure your surface is clean and free of any dirt, oils, or foreign substances. A product like Tri-Sodium Phosphate (TSP) can effectively clean the surface without leaving an oily residue. It is important to note that if you intend to use Extra-Bond, a bonding agent specifically designed for milk paint, you can avoid extensive surface preparation, such as sanding.
Bonding Agents
If you are painting onto challenging surfaces like glass, metal, or plastic, consider using a bonding agent like Extra-Bond or Ultra Bond. These agents improve the adhesion of milk paint to non-porous or previously finished pieces. When using a bonding agent, follow the recommended ratios provided by the manufacturer. Typically, a 1:1 ratio of paint to bond is suggested, but you can adjust the amount of bond depending on your desired level of chipping.
Application Technique
When mixing milk paint, use a milk frother and rest it on the bottom of the container while applying pressure. Mix for a maximum of 20-30 seconds to avoid over-frothing. Let it sit for a few minutes, allowing the water to absorb into the powder, and then give it another quick mix. If foam forms, skim it off before adding the bonding agent. Stir to combine, and remember to mix occasionally during use to prevent settling.
Multiple Coats
For the best colour and coverage, it is recommended to apply two coats of milk paint to your surface. When calculating the required amount of paint, consider the total square footage, including multiple coats. For example, a 10' x 10' wall with two coats would require 200 square feet of coverage.
By following these guidelines, you can ensure that your milk paint achieves the strongest bond when applied fresh to your desired surface. Remember to properly prepare your surface, consider using bonding agents for challenging surfaces, and apply multiple coats for optimal results.
