What do you put on epoxy after sanding? This is a common question among DIY enthusiasts and professionals alike. After applying epoxy to a surface, sanding is often the next step to ensure a smooth, even finish. However, it’s crucial to understand what to apply after sanding to achieve the best results. In this article, we will discuss the various options available for finishing your epoxy-coated surface.
Epoxy is a versatile material that can be used for a wide range of applications, from repairing cracks in concrete to creating a durable, waterproof seal on wooden decks. Once the epoxy has cured, sanding is necessary to remove any imperfections, such as air bubbles, brush marks, or uneven surfaces. After sanding, there are several options to consider for the final finish:
1. Clear Coating: Applying a clear coat over the sanded epoxy is a popular choice. Clear coatings provide additional protection against UV rays, moisture, and wear. They also enhance the appearance of the epoxy by giving it a glossy or matte finish, depending on your preference. Common clear coatings for epoxy include polyurethane, polyaspartic, and polyurethane-modified polyurethane.
2. Topcoat: A topcoat is another option for finishing your epoxy surface. It is similar to a clear coat but offers better resistance to chemicals, solvents, and stains. Topcoats are often used in industrial applications where durability is a priority. Examples of topcoats for epoxy include polyurethane, polyurea, and polyvinylidene fluoride (PVDF).
3. Polishing Compound: If you desire a high-gloss finish, you can use a polishing compound after sanding. This method involves applying a fine-grit polishing compound to the surface and then using a buffing pad or machine to achieve a smooth, shiny finish. Polishing compounds are available in various grit levels, with finer grits providing a higher shine.
4. Sealer: In some cases, a sealer may be applied after sanding to provide additional protection against moisture and stains. Sealers are often used on outdoor surfaces, such as patios and driveways, to prevent water damage and extend the life of the epoxy coating.
When choosing the right finish for your epoxy surface, consider the following factors:
– Application: Determine the intended use of the epoxy surface. For example, a clear coat may be sufficient for a decorative purpose, while a topcoat is better suited for high-traffic areas or industrial applications.
– Durability: Consider the level of protection you need. A topcoat or sealer may be necessary for surfaces exposed to harsh conditions or chemicals.
– Appearance: Decide on the desired finish, whether it’s a glossy, matte, or satin appearance.
– Maintenance: Consider how much time and effort you’re willing to invest in maintaining the surface. Some finishes require more frequent maintenance than others.
In conclusion, what you put on epoxy after sanding depends on your specific needs and preferences. By choosing the right finish, you can achieve a durable, aesthetically pleasing, and long-lasting result.
