If you have old metal corral panels that you want to paint so that you can make them look new again and get more life from them, you will need to know how to prepare the panels for painting. Also, you can use a few tips and tricks to make painting the panels easier and cause the paint to adhere better. With that in mind, here are some tips that will make painting the old metal panels easier and more effective.
1. Get Rid of Rust
Before you can paint your metal corral panels, you need to make sure that they are free from corrosion and rust. In order to remove rust buildup on the panels, use a wire brush to aggressively scrub areas where rust or corrosion damage appears. This will help paint better adhere to the surface of the metal panels and also help reduce additional rust and corrosion damage in the future.
2. Use a Home Made Sealant Mixture
After you scrub away rust and corrosion, you can use an excellent homemade sealant to further protect your metal horse corral panels. Take a mixture of half turpentine and half linseed oil and brush it on to the metal surface of the corral panels. Allow the mixture to sit on the panels overnight and you will have created an excellent protectant for the panel that will help to resist rust and corrosion.
3. Always Prime the Panels
Even if you use the special homemade sealant to seal your metal panels, you should always use a high quality exterior primer before applying a good enamel or oil-based paint. Primer will help to create a better bond between the metal surface and the paint. Primer will also help reduce chipping and cracking in the paint on your metal corral panels.
4. Use Rust Resistant Exterior Paint
When choosing a paint for your corral panels, always use a quality rust resistant exterior paint. Because the panels are used outside, you will naturally want to choose an enamel or oil-based paint. However, spend a few more dollars and buy a paint that also has a rust and corrosion prevention additive included.
5. Reduce the Cost of Polyurethane with Linseed Oil
You can reduce the amount of polyurethane clear coat that you will apply over the painted surface of your metal corral panels by brushing on a couple of coats of pure linseed oil. Linseed oil has excellent protective properties and will also help to fill the pores in the paint on the surface of the metal corral panels. In fact, a couple of coats of linseed oil will help reduce the amount of polyurethane clear coat you need to use by about 75 percent.
6. Always Seal with a Clear Coat
After applying a couple of coats of linseed oil, choose a good quality polyurethane protectant. The clearcoat will protect the paint finish on your corral panels and also help them to resist rust and corrosion. A good clearcoat finish will also make the panels much easier to clean.
