Benefits of DTM Metal Painting
Monday, 25 May 2020 | Admin
In the past, painting metal was difficult. The key to paint staying on a surface and covering it requires the surface tension of the metal be greater than that of the paint being applied. If it is, then the paint spreads nicely and evenly, but if not, it won’t adhere to the surface. We refer to this as “wetting out”, and is essentially the paint following the shape of the metal being painted, and interlocking with it forming a strong bond.
This is why direct to metal paints were created. They remove this issue and spread easily and evenly on clean metal surfaces. Buzzweld has the DTM paints you need for painting automobiles and other surfaces. We’ll discuss why DTM painting could be the best choice for you.
The Problem with Painting Metals
We discussed a little about what makes painting metal a problem. It’s a matter of surface tension. The problem with most paints is they don’t have what it takes to properly coat the metal- Stonechip is notorious for this problem, as well as poorly applied powdercoat. The only way to remedy this is to increase the surface tension of the metal through preparation- sanding or sandblasting and the use of a primer.
Since this is your automobile, odds are you’re not a big fan of that idea (unless this is a full restoration). It eliminates the protective coatings on the metal. The other option is to lower the surface tension of the paint, which is how direct to metal painting came about through improved wetting out ability removing the need for a primer all together, whilst incorporating the benefits of a top coat.
The paint adheres to the surface without the need for a primer. It’s ideal for automotive applications and is considerably more cost-effective than other methods like using a primer and top coat as separate products.
How to Use Your DTM Paints
Prepare your painting surface by making sure it’s dry, clean, and has no grease, dirt, or other particles that could interfere with the painting process. If you have rust or scale, then it must be removed to a level minimum of ST3. Use a rust Converter like Rust-Prime on rust. By preparing the surface you are reducing the surface tension, and allowing DTM to wet out and form a correct bond.
Now that your surface is prepared, carefully coat the surface, and then wait for a few hours before continuing with a second coat if not using an airless sprayer.
Benefits of Direct to Metal Paints
Buzzweld DTM Direct To Metal Satin isn’t just any DTM paint, but the best available. Unlike many other DTM paints that required multiple applications, ours is Glass Flake Impregnated and only requires a single coat when using an airless spray or other similar methods.
It’s known for its high durability and resistance to common rust causes such as seawater, shipping, and corrosion. It provides a high level of adhesion and is long-lasting. You can use it on your car, boat, and other applications in extremely aggressive environments.
There are even colour tinting capabilities to make sure it matches the surface. Our DTM paints are compatible with most cured paint systems and are ideal for chassis, underbody, axles, and body.
DTM Painting Doesn’t Have to Be a Hassle
You love your car and want it to look it’s best and using Buzzweld DTM Direct To Metal Satin makes sure that happens. Don’t trust your metal surfaces to anything else.
