To stop the oxidation process from continuing, it’s crucial to remove all of it. You run the risk of your rust spreading. This is why covering rust by merely sanding and painting isn’t the best option.
- Close up all gaps
Use car body filler or similar metal-specific bonding solution to repair any holes in the door. Use fine-grit paper to sand the area once the filler has dried. After that, sand the whole door. When finished, use a brush or dry towel to remove any dust.
3) Clean the door
Prior to painting, the door must be completely cleaned since grease and debris will prevent the paint from adhering. Additionally, painting over any pieces of debris may create lumps on the surface, so avoid doing so. Warm water and dish soap will work just fine, but trisodium phosphate in warm water will provide the greatest results (TSP). Follow the instructions on the product’s package to calculate the TSP to water ratio. Finally, give the garage door a good cleaning with your hose before letting it air dry.
4.) Paint the entrance.
Your garage door needs primer and paint. Make sure you use rust-resistant primer and paint made specifically for metal garage doors. Always verify if the garage door’s maker suggests using certain painting supplies and methods.
A paint sprayer is the most effective tool for painting a garage door. The slots in the door panels make it possible that paintbrushes and rollers will leave dripping marks. It may be necessary to use two coats of paint. Alternatively, you might decide to use a paintbrush rather than a sprayer to apply primer and paint just to the areas where the rust was removed, followed by a final coat to cover the whole door. Always let the primer and paint fully dry in between layers.
It is advised that you paint the whole door rather than only using primer and paint to fix up the damaged sections. Otherwise, flashing is likely to happen, which will make the door suffer since the freshly painted parts will show out against the rest of the door.
Only paint your garage door while it’s warm outside; painting it when it’s chilly outside can only end badly. Additionally, before you begin, check the weather to ensure there won’t be any rain for at least a few days.
