Painting Metal Surfaces to Last
Anyone who has had need to paint metal surfaces or who is a professional with working with metals, painting and such knows fully well that painting metal is way different from painting ordinary surfaces like wooden surfaces or plain walls. First off, the preparation for painting metal surfaces, especially if you want your paint job to last, involves a lot of planning and preparation. Whether you are an amateur painter doing your first DIY painting of household metal surfaces, or just trying to cut down on the cost of hiring a professional, then you should consider following these steps that we will now proceed to list out towards making your first paint job look so much like a professionally done job.
Really Clean the Surface Properly:
Preparing a metal surface for painting that is guaranteed to last is a very delicate process. Before commencing, you need to make sure the surface smooth and adhesive. To achieve this, you can apply Wil-Bond to help remove the grease and apply a rust-inhibitive primer. For previously painted surfaces which are still in fair condition, you can remove the dust with a clean and dry cloth and then de-gloss the surface of the metal with light sanding and a bonding agent for adhesion. In some cases, you may require some mild detergent to wash off stubborn dirt before commencing painting. Following this process is guaranteed to give you a smooth and neat painting job by the time you are done and the application of Wil-Bond helps with adhesion for long life.
Removing Loose Paint:
In situations where you are required or require the removal of loose and peeling paint, that is when the paint is in terrible condition, then consider removing it by the use of hand wire brush method, scraping with a mildly hard material or sanding. The one downside of this method of removing old paint peels is that it is laborious and could tire you quickly. There is the alternative of using power tools but these tools often polish the metal surfaces off and leave you with an adhesion problem. So, it’s preferable to just stick with the manual stuff.
Repair Holes and Prime the Surface:
Preparing the surface, again, is the core aspect of painting a metal object or surface. So, focus most of your time on the processes that deal with this aspect. Repair all holes in the object or surface and prime the surface. Priming goes a long way to determine how the metal would perform. As a result, you need to be careful when selecting the right primer. So, consider the type of metal to be coated, the appearance desired, environmental variables and performance parameters when choosing a primer that will last. When you have this part, pick a suitable color of paint and proceed.
Remember galvanized or aluminum metal may need “neutralizing. We have found it’s best to use a vinegar solution on galvanized metal. If your painting aluminum it’s been recommended to use baking soda to insure proper prep.
