It is not compatible with enamel or oil-based paints
When preparing Permalac for application, it is important to ensure that the surface is free of grease, dust, and moisture. The substrate should be degreased and dry, and you can use a mild soap and water solution before wiping it down with a solvent. Permalac is compatible with various surfaces, including metal, masonry, and wood, and it can be applied over certain types of paint.
However, it is important to note that Permalac is not compatible with enamel or oil-based paints. This incompatibility is due to the chemical makeup of these paints. Enamel paints, also known as alkyd or oil-based enamels, are typically made with a higher percentage of resin and have a harder finish. This chemical composition is not suitable for applying Permalac on top.
Similarly, oil-based paints, also known as alkyd or solvent-based paints, have a different chemical composition compared to Permalac, making them incompatible. Oil-based paints contain linseed oil or another similar drying oil, which gives them their characteristic slow-drying property. The oil in these paints can interfere with the adhesion and curing process of Permalac, leading to improper bonding and an uneven finish.
It is crucial to exercise caution when working with Permalac and to always test it on a small area before proceeding with a full application. This is especially important when dealing with surfaces that may have been previously painted with enamel or oil-based paints. In such cases, it may be necessary to consider alternative coatings or seek professional advice to ensure the desired results.
To avoid issues with compatibility, it is recommended to use Permalac with compatible paint types, such as acrylic, solvent-based, or latex-based paints. These paints have the necessary chemical properties that allow Permalac to adhere and cure properly, resulting in a durable and uniform finish. By following these guidelines and choosing the right type of paint, you can ensure the best outcome for your project when using Permalac.

Surfaces should be free of grease, dust, and moisture
To ensure the surface is free of grease, you can use a degreaser. Choose the right degreaser based on the contamination type and material. Water-based degreasers are suitable for light to medium contamination, while solvent-based degreasers, such as mineral spirits and denatured alcohol, are better for heavy grease and oil removal. Before applying the degreaser, protect yourself with personal protective equipment (PPE) and test the degreaser on a small area. Then, apply the degreaser, scrub the surface, rinse, and wipe it clean. Let the surface dry and inspect for remaining contamination.
To remove dust and moisture, you can use a brush or a cloth to wipe down the surface. If there is caked-on grease or heavy contamination, you may need to use a stronger method, such as mechanical degreasing. This involves using an abrasive material, such as a brush or abrasive pad, to scrub the surface. You can also use a vacuum to remove loose dust and debris. Always start with the least aggressive method and work your way up if needed.
It is important to ensure that the surface is completely dry before applying Permalac. Even a small amount of moisture can affect the paint's adherence. If you are painting outdoors, check the weather forecast to avoid rain. You can also protect your surfaces with drop cloths or masking tape to ensure a clean finish.

Use lacquer thinner or acetone to wipe down the surface
When preparing a surface for painting, it is essential to ensure that the surface is free of grease, dust, and moisture. This step is crucial to achieve a smooth and even paint application. One effective method to achieve this is by using lacquer thinner or acetone to wipe down the surface.
Lacquer thinner is a popular choice for surface preparation as it effectively removes grease, dust, and other contaminants. It is a strong solvent that can break down and dissolve these impurities, ensuring a clean surface for painting. However, it is important to note that lacquer thinner may contain different chemicals and evaporate slower than other options, leaving a residue behind. This residue can be removed by using a second clean, dry rag to wipe down the surface before the thinner dries.
Acetone, on the other hand, is a highly effective solvent that evaporates quickly and leaves no residue. It is often favoured for its ability to thoroughly clean the surface without any leftover film or streaks. To use acetone effectively, it is recommended to wipe the surface with acetone using one rag, and then follow up with a second clean, dry rag to wipe off any remaining acetone. This two-step process ensures a streak-free and residue-free surface.
When deciding between lacquer thinner and acetone, it is important to consider the specific requirements of the project and the characteristics of each solvent. While lacquer thinner is more cost-effective and readily available, acetone offers a faster-drying and residue-free finish. Additionally, it is always advisable to test a small area first to ensure the desired results.
To further enhance the surface preparation, it is recommended to clean the surface with a mild soap and water solution before wiping it down with the chosen solvent. This additional step ensures that any remaining impurities are removed, resulting in a clean and prepared surface that is ready for painting.

Permalac can be sprayed, brushed, or dipped
When it comes to applying Permalac, you have three options: spraying, brushing, or dipping. Each method is unique and effective in its own right, and the best choice for you will depend on the specifics of your project.
Spraying Permalac is a popular choice, especially for smaller jobs, as it can be easily applied using an aerosol can or spray gun. This method ensures an even and consistent coat, but it's important to remember to shake the can well before spraying or to stir the solution if using a spray gun. Thinning the Permalac before spraying is also recommended, and commercially available lacquer thinners can be used for this purpose. The mix ratio is typically four parts Permalac to one part thinner, but this can be adjusted to three parts Permalac to one part thinner if conditions are hot and dry or the substrate is porous. For spraying steel, a mix ratio of one part Permalac to one part thinner is used for the first coat.
Brushing on Permalac is another option, ideal for those who want more control over the application process. This method allows for a precise and careful application, ensuring that every inch of the surface is coated. Brushing can be a more time-consuming process than spraying, but it can be worth it for the added precision.
Dipping is the third Permalac application method. This involves submerging the object to be coated in Permalac, ensuring that all surfaces are completely covered. This method is often used for smaller items that can be easily manipulated, as the Permalac can be poured into a container and the object dipped directly into it.
No matter which application method you choose, it's important to remember that Permalac should only be applied to clean and dry surfaces that are free of grease, dust, and moisture. Additionally, Permalac is compatible with most acrylic, solvent-based, and latex paints but should not be used over enamels or oil-based paints due to chemical incompatibility. Always test on a small area first to ensure compatibility and allow sufficient cure time before exposing the coated surface to wear and tear.
