# How do you properly remove paint from a metal surface before repainting?

Removing old paint from a metal surface is an essential step in ensuring a smooth and durable new coat of paint. Whether you're restoring garden furniture, industrial equipment or decorative pieces, careful preparation is the key to success. This article will guide you through the best practices for effectively removing paint, using TIVOLY wire brushes adapted to this purpose.

1-    The importance of good preparation
Before we begin, it's crucial to understand why properly removing old paint and preparing the surface is fundamental: 

Increased adhesion: The new paint adheres better to a clean, well-prepared surface, increasing the durability and strength of the finish. 

Aesthetics: A properly prepared surface ensures a smooth and flawless finish, which is essential for a quality aesthetic appearance. 

Corrosion protection: By removing rust and old paint, you protect the metal from future corrosion and damage.

2-    Selecting the right tools
Selecting the right tools to remove paint is fundamental. TIVOLY wire brushes, designed to be effective and durable, are perfect for this job. They remove paint and rust without damaging the underlying metal. 

Types of brushes: Opt for a steel wire brush for heavy-duty work or a brass wire brush for more delicate surfaces. 

Safety: Be sure to wear personal protective equipment, such as gloves, safety glasses, and a dust mask, as the process can generate volatile particles.

3-    Cleaning & Preparation Process
The metal surface preparation process includes several key steps to ensure the best possible result. First, an initial cleaning with a strong degreaser to clean the surface of any oil, grease, and other contaminants. This cleaning ensures that nothing prevents the adhesion of the new paint. Next, using a wire brush to remove peeling paint and rust. Use smooth, even motions to avoid scratching the metal. After removing most of the paint, use a fine-grit sandpaper to smooth the surface. This helps to create an evenly textured surface that promotes better adhesion of the new paint.

4-    Applying the new paint
After the metal surface has been cleaned, degreased, sanded and all the old paint and rust have been removed, it is time to move on to the painting phase. Here is a detailed explanation of this crucial step:

Paint selection : The choice of paint is crucial to ensure both the durability and aesthetics of your project. 

For metal surfaces, opt for paints formulated specifically for metal, which offer superior adhesion and resistance to corrosion and weathering. 

If the metal is prone to rust, consider using an anti-rust paint that acts as a primer and protective topcoat. 

And finally, the choice of finish, which can be glossy, satin or matte, depending on the desired appearance and the environment where the metal will be exposed.

Paint preparation : Before you start painting, make sure the paint is well mixed to even out the color and consistency. For paints that require thinner, follow the manufacturer's instructions to thin the paint with the correct solvent, this ensures a smooth and even application. It is recommended that you test the paint on a small, non-visible section to ensure that the color and finish meet your expectations.

Application technique : Paint application must be done carefully to prevent dripping and ensure even coverage. Use a high-quality brush for edges and small details, and a roller for large, flat areas. This helps to apply the paint evenly. For larger projects or to achieve a very smooth finish, a spray gun can also be an effective option. Be sure to maintain a constant distance between the gun and the surface for a consistent application.

Layered application : Apply several thin coats rather than one thick coat. This helps prevent dripping and ensures that the paint dries evenly and adheres properly. Observe the drying times between coats, as recommended by the manufacturer. This allows each coat to dry properly before the next one is applied.

Finishes and touch-ups : After the last coat has dried, inspect the surface for any defects or missed areas. Apply touch-ups if necessary. For metal surfaces exposed to severe outdoor conditions, consider applying a clear protective varnish to prolong the durability and shine of the paint.

# TIVOLY advice:

TIVOLY recommends that you never underestimate the importance of careful surface preparation, emphasizing that this is essential to ensure a blemish-free finish and increased durability of the paint. The use of high-quality TIVOLY brushes allows for efficient preparation without damaging the metal, making it easier to remove old paint and rust. It's also crucial to take your time every step of the way, from cleaning to painting, to ensure a professional result. TIVOLY advises to strictly follow the manufacturer's instructions for each product used, including drying times and recommendations for optimal application conditions, such as temperature and humidity. The company also insists on the use of appropriate techniques for paint application, such as the use of high-quality brushes and rollers or a paint gun for large projects, to ensure a homogeneous and flawless application. Finally, TIVOLY encourages regularly checking the surface condition during the painting process to ensure that the coverage is uniform and to make touch-ups if necessary, thus ensuring the highest quality and longevity of the finish.
