DIY Rust Repair
One of the most common repair works at home that can leave a hole in the wallet is rust repair. Rust is found usually on items and places that are exposed to moisture, air and salt very frequently. Metals like iron and steel develop rust as they react easily with moisture and air. The rust leaves a brown patch or spot on the metal and it looks very unpleasant, old and thus eroding the material´s strength. One of the most important aspects of household cleaning is stain removal from metal items in the home. After reading this article, anyone with limited resources should be able to do rust repair at home.
Step 1 – Identification of Rust Spots
The initial step involves identifying all the spots that have rusted or are currently undergoing the process of oxidation. For this use a small knife or paint remover tool. Gently try to remove the paint from an area that is easily accessible. Use a small headed, but light, hammer to tap and identify the weak spots on the metal. Use the marker to draw a small square shaped box around the rust spot.
Step 2 – Remove Rust
Place paper beneath the metal. Now start removing the rust from the identified spot using the sand paper. Remove all the dust by blowing air over the spot. Take care so that this rust dust is not spread to other items in or around the home.
Step 3 – Fill the Holes
If there are any holes left back in the metal surface after removing the rust then these holes need to be filled to prevent further problem. Use repair substances such as Bondo, which is used to fill up small holes and patches. Wait for the Bondo to dry up. Check if the hole is closed.
Step 4 – Primer Coating
It is necessary to place a primer coat to the old rust spot to make it rust proof. It is one essential step that must be performed or else the rust repair is incomplete; moreover, the rusting will start again very soon. Apply the primer coat in and around the area of the rust zone and let it dry completely. Sometimes applying 2 to 3 coatings of the primer is beneficial.
Step 5 – Paint the Spot
Generally, the rust spot is painted in the same color of the metal item. However, sometimes the whole piece of furniture or metal accessory is painted completely in a new color. The purpose of painting is to enhance the life of the metal by protecting it from oxygen and moisture. It saves the metal from becoming brittle and weak. It may also be an opportunity to improve the aesthetic value of the item.
If the holes in the metal surface are small, then Bondo works well; however, if the holes are large enough then it might require welding. For welding, use a rectangular piece of metal strip larger than the actual hole and weld. Weld to close all the gaps and cover a larger zone including the rust spot. The purpose is to cut out the rust agents completely. This is not recommended unless the welder is experienced.
